Over the past month, he and Huangfu Nitian had a deep relationship. Huangfu Nitian guided him with harsh and patient guidance on his combat skills, as well as how to use the terrain and the enemy's psychology to defeat the enemy. Although these have nothing to do with martial arts and practice, they have a fundamental role in the victory or defeat of the battle.

"This..." Huangfu Nitian pondered for a while, and then said, "If you have any urgent matters, go to the training camp to find my grandfather! Please tell me that he will tell me. But if there is no urgent matter, don't look for me!"

"Okay!" Jiang Chen said reluctantly.

"Let's go! We're back!" Huangfu Nitian said with a little sadness. Then he put his fingers on his lips and blew hard, and the whistle sounded throughout the sky...

After a while, the sea eagle Huanhuan also flapped its wings and slowly landed from the air.

...

Jiang Chen was floating above the sea outside the misty waters, and he was flying towards Ziwu Island. Huangfu Nitian had already rode his Huanhuan Sea Eagle away. Before parting, he gave himself a book called "The Killer's Guide", which mainly introduces some basic skills of the Killer and how to practice assassination.

In fact, this book can also be borrowed in the Sutra Library of the training camp, but Huangfu Nitian put forward his own opinions on the assassination and fighting methods on the title page of this book. However, Huangfu Nitian repeatedly reminded Jiang Chen that it is best not to practice the two methods of ghost path and thunder system until the Golden Elixir stage.

Jiang Chen then recalled the scene before parting:

"Why can't I practice thunder-type martial arts now?" Jiang Chen, holding the "Killer's Guide", stared at Huangfu Nitian, who was still wearing a mask, and asked in confusion. He told Huangfu Nitian that he wanted to practice thunder-type martial arts immediately, but Huangfu Nitian rejected it.

He explained: "If the Foundation Establishment Stage is considered a true immortal cultivator, then the Golden Pill stage has a real foundation on the road to immortal cultivation. You told me that you are an alchemist, so although you are a mixed spirit root, the cultivation speed is not slow because you have a large amount of elixirs to take. Then you should know that if the alchemist reaches the Golden Pill stage, you can generate elixir fire in your body, and you can refine elixirs without using earth fire. And mastering elixir fire is easier than that of earth fire. This is why all alchemists above the fourth level are cultivators above the Golden Pill stage, but there is no foundation establishment stage cultivator."

After pausing, Huangfu Nitian said again: "And the natal magic weapon, a crucial thing for cultivators, can only be sacrificed and refined in the Golden Elixir stage. The combat power of the cultivators with powerful natal magic weapons is far from comparable to that of the foundation-building cultivators. Moreover, after the dantian of the golden elixir stage is solidified into the golden elixir, the accommodation and condensation of the magic power has reached a new level. Even if you practice two completely opposite techniques, you still have enough magic power to mobilize. However, in the foundation-building stage, even in the late stage of foundation-building, or even the Great Perfection of the Foundation-building stage, it is difficult to achieve this!"

Speaking of this, Huangfu Nitianfang said with some emotion: "So, after Jiang Chen, after you reach the Golden Elixir stage, you may have improved your understanding. But now you only have the foundation-building stage cultivation, and you are still young. It is the golden time for your cultivation, so you should just practice one kind of exercise with peace of mind."

"How many thunder cultivators dream of becoming a ghost cultivator... After all, many of the skills of ghost cultivators are very powerful! But I didn't expect that you, the ghost cultivator, always want to be a thunder cultivator..." Huangfu Nitian's voice sounded in Jiang Chen's ears.

"It seems that I have to work harder after going back to the training camp. Try to break through to the Golden Pill stage as soon as possible." Jiang Chen thought to himself while flying towards Ziwu Island.

After arriving at Ziwu Island, Jiang Chen handed over all the demon pills he obtained to the Shang League branch and showed his identity as a disciple of the Demon Sect Training Camp. This made the maid in charge of receiving the Shang League awe.

He actually brought more than 560 demon pills in total, ranging from fourth to ninth level monsters, which surprised the monks in charge of the identification of the Shang Alliance.

After conducting a full appraisal, Fang said to Jiang Chen: "Fellow Daoist Jiang, after we have identified these demon pills, you can exchange for a total of 4,760 points of military achievements. You can also exchange them for 4,760,000 spirit stones. Do you think you want to exchange for military achievements or spirit stones?"

"Of course it's a military achievement! I'm a disciple of the Demon Sect Training Camp! I can't use too many spirit stones in the training camp!" Jiang Chen said in a voice.

"Okay! Please take down your jade pendant and give it to us. We will help you enter the military merit points into it!" said the appraiser.

Jiang Chen took off the jade pendant and handed it over. After the appraiser entered the military merit point, he handed it to Jiang Chen and said, "It has been charged, you can penetrate the spiritual sense into the query at any time!"

Jiang Chen nodded, took the jade pendant and looked at it for a while, then went to the place where the teleportation array was located. Then teleported back to the Holy Island.

After returning to the Magic Sect Training Camp, he looked at the time. It was the 29th day and the month was over.

"I'll go to the trial tower to measure the potential index on the last day. I'll practice sword technique again today!" Jiang Chen thought to himself.

At this time, Zi Xi, who learned that Jiang Chen had returned, saw that he had experienced the trip to the Purple Misty Sea, was indeed much more mature and steady, and his temperament made people feel a sharp murderous aura.

Zi Xi was also very happy. She did not criticize him for conducting potential index tests in the future last month, so she began to conduct devilish training on him again...

"Jiang Chen! The sword technique realm is divided into four levels: basics - specialization - perfection - perfection. You can lay a solid foundation for me now! Now I will practice swords for these four hours! In the sword technique training room, practice well against those puppets! How can I do if my foundation is not solid?"

"When practicing, you have to use your brain and think carefully! How can you make the sword technique continuous like flowing water! You can't deal with moves by chance! You can split each move, do you understand?" Zi Xi shouted.

"Yes, Xi'er!" Jiang Chen kissed her pretty face, and then said that he would work harder.

All day long, Jiang Chen was obsessed with practicing sword techniques, and also used his spiritual sense to sense the trajectory of the flying sword flying out. With the careful sensing of the spiritual sense, as well as his perception and experience on the edge of life and death in the mist waters, Jiang Chen was also constantly improving his sword technique realm and practicing hard.

"It seems that Chen'er came back from the Ziwu Sea. The progress is really scary, but there are many perverts entering this Magic Sect training camp. I heard that Hu Xuesong is even more abnormal." Although Zi Xi was shocked, she had higher requirements for Jiang Chen. She did not have a chance to talk about him because of his intimate relationship with him.

She kept adding various training methods to Jiang Chen without any relaxation.

On the next day, the last day of the month when I entered the trial tower to test the "Potential Index" finally arrived.

Since many people have the same idea as Jiang Chen, they have to test their potential index this month on the last day of a month. After all, this is the time of the strongest strength in a month.

So many people gathered before the trial tower and lined up in a long queue.

After it was his turn, Jiang Chen handed the jade pendant to the guard at the entrance of the trial tower.

The guard recorded it for a moment, then waved his hand to let him in, and then asked the next person to come up and register...

Jiang Chen knew that this trial tower was also a virtual space. It was a bit like the demon lock tower he experienced in the finals, but the trial tower was very small, and each floor was just a hall.

However, the trial tower is thirty stories high, much higher than the Demon Locking Tower. If you participate in the "Potential Index" test, you need to climb up one by one, and every time you climb to another, the potential index will increase a little.

After Jiang Chen stepped inside, a mysterious figure with a golden mask appeared in the first floor. The mysterious man held a hundred ghost banner in his left hand and a soul-breaking sword in his right hand. Under the golden mask, he stared at Jiang Chen and said, "I am your opponent. If you defeat me, you can enter the second floor! Start the battle!"

"A opponent holding the Hundred Ghost Banner like me and using the Soul-Breaking Sword?" Jiang Chen's pupils shrank, and his mind moved. The Hundred Ghost Banner immediately spewed out a ball of black mist, condensing into a black dragon. He rushed straight towards the golden-faced man, and then waved his sleeves, and purple flying knives flew out from his sleeves, and a total of six thunderous flying knives flew out.

Although the number of thunder flying swords controlled by Jiang Chen has not changed, his spiritual sense and magic weapon control ability have been surprisingly improved during the trial of the Misty Waters in the past half month.

"Kill!" The golden-faced man roared and rushed over.

The Hundred Ghost Banner in his left hand also spewed out a mass of ghost mist, condensed into a black dragon and Jiang Chen's Hundred Ghost Banner to fight.

At the same time, the soul-breaking sword in his right hand also drew several sharp sword lights and attacked Jiang Chen.

Both of them rushed towards each other quickly at the same time, but one side controlled eight thunderbolt flying knives, and the other side controlled a golden soul-breaking knife.

"Hmph, I have never relaxed in practice this month. Compared to the selection competition, I am much stronger! Let you test my current strength!" Jiang Chen's eyes were full of fighting spirit, and the golden sword in his hand seemed to be very skilled in an instant. They cooperated with each other and directly pressed and strangled them!

"Clang! Clang! Clang! Clang!"

In the air, the purple flying knife in Jiang Chen's hand and the soul-breaking knife in the golden-faced man's hand carried out crazy attacks and impacts again and again.

"What's going on?" Jiang Chen was slightly shocked.

Before entering the Magic Sect Training Camp, he could control six thundering flying knives to attack the enemy at the same time. Now he could control seven thundering swords for attack.

However, to be on the safe side, Jiang Chen chose to only use the six-handled flying sword main attack, because he was very familiar with some of the combat methods of the six-handled flying sword joint attack.

However, what he didn't expect was that his opponent actually blocked the attack of the Thunder Flying Knife.

"I actually blocked it, I don't believe it!" Jiang Chen's eyes turned cold. Then the spiritual power in his hand activated, increasing the transmission of magic power.

The thunder flying knife in his hand immediately dispersed again, attacking the golden-faced man from six different directions, as if cooperating with the wonderful six masters, advancing and retreating from each other, very perfect. After repeated attacks, he attempted to break through the obstacles of the thunder flying knife in the golden-faced man's hand and kill the enemy.

However, several attacks failed. Although the golden-faced man controlled the soul-breaking sword, it had a special artistic conception, as if this big sword was a perfect whole! It sometimes gives people the feeling of endless tsunamis and waves oppressing! Sometimes it looks like a towering mountain that makes people feel unshakable!

"How is this possible?" Jiang Chen said in shock: "I controlled six flying knives. He only controlled one soul-breaking knife. Why can't I gain any advantage?"

He tried every means to make the six flying swords cooperate exquisitely, but the opponent was still floating far away, and he could easily resist it by just controlling a big sword.

"Silly, I don't even understand this." A pair of eyes exposed under the golden mask of the golden man showed a hint of sarcasm: "At this level, I'm trying to pass the first level, die!"

With a "swoosh", he began to turn from defense to attack.

The soul-breaking sword controlled by the golden-faced man suddenly flashed by golden light on the blade, as if it turned into a giant scimitar that wanted to break through the sky, and rushed towards Jiang Chen.

Jiang Chen was secretly shocked and even controlled six flying knives to stop them. With a loud "boom", Jiang Chen's six purple flying knives were all knocked back.

"How could this happen?" Jiang Chen, who was in the air in the distance, was shocked.

At this time, he gritted his teeth, a cold light flashed in his eyes, and he shouted in a low voice: "Cracking the Sword Formation!"

With a loud "boom", one purple flying knives after another flew out of Jiang Chen's sleeves, forming a purple knife array composed of thirty-two flying knives around his body.

The six thunder flying, which had been knocked back before, also circled back again and stayed in front of Jiang Chen.

At the same time, a dazzling golden light burst out from Jiang Chen's body. The golden light spreads around like waves, and then quickly wraps around the six thunder flying knives in front of him. The six flying knives rushed towards the golden-faced man like a six-pointed star array!

There are golden threads connected to each other between the six purple flying knives. The purple arc bursts out toward the surroundings with the six purple flying knives as the center.

For a moment, in the semicircular space with Jiang Chen as the center and a radius of 30 meters, a dazzling world of sword energy instantly became, with countless golden sword energy and arcs wandering vertically and horizontally in this semicircular space.

"I admit that you are very strong, but you still have to lose in front of me trying my best!" Jiang Chen controlled six thunderous swords and rushed towards the golden-faced man in front of him like lightning.

With a loud "boom", the golden-faced man's soul-breaking sword was finally destroyed, and his chest was also shattered by six purple flying swords, and he fell to the ground and died.

At this time, a voice sounded in the trial tower: "You have defeated the guardians on the first floor, and your potential index is one, so you can enter the second floor! Will you continue to challenge?"

"Continue!" Jiang Chen replied without hesitation.
Chapter completed!
