The true immortal Wufeng can travel outside the sky, and naturally he can travel underground. His divine thoughts pass through countless soil layers and rocks, as simple and easy as swimming.

Wufeng Zhenxian snorted coldly and said, "Tang Letian, are you trying to treat me as a slave?"

Tang Letian hurriedly said, "True Immortal, why did you have such an idea? You see, how many times I called you, which one did it without having to do it? This time I really don't have much time to search here little by little, and for you, it's easy to dive into the underground to find an underground space."

The True Immortal Wufeng snorted coldly again. Tang Letian waited for a while, but did not hear the answer from the True Immortal Wufeng. Just as he was about to speak, a loud noise like a mountain shaking came suddenly from afar. The ground at Tang Letian's feet began to tremble.

Tang Letian was delighted and immediately ran towards the place where the sound came.

Sure enough, a big hole appeared on the ground, and the True Immortal Wufeng took action to break open a hole that penetrated into the underground space.

Tang Letian praised in his heart, it was so easy to use. It was so convenient to have such a baby who could be ordered by him at will. If he was himself, it would take at least several days to find the entrance to the underground cave. It would have to be lucky. Now, in just a moment, he found the cave. Wufeng True Immortal also deliberately exploded an entrance. It was not bad, so I really should reward Wufeng True Immortal.

But Tang Letian didn't dare to do this, after all, she didn't want to die young.

Tang Letian looked towards the dark underground. There were various tall giant trees around the entrance of the cave, each with a huge tree of 10 meters. Under the cover, there was no sunshine here, covered with moss, and countless huge rotten fallen leaves covering the entire ground.

It can be said that even without the steep boulders, this place is still an extremely hidden place.

Tang Letian jumped into this underground space.

Tang Letian threw out several balls of fire, instantly illuminating the underground space.

This is an underground cave. Although the situation on the ground is completely different from that in Tang Letian's memory, the situation on the ground is completely consistent with Tang Letian's memory. It seems that thousands of years have not changed anything in this underground cave.

Tang Letian fell in the cave but was exactly the same as the bottom of the cave. This was cold groundwater that was waist-deep. The entire underground cave was more than 30 meters high. Water dripping dripping from the four walls of the cave. When it hit the groundwater, it made a tinging sound, which made the entire cave seem to be playing a wonderful music, and walking through it makes people feel pleasant and comfortable.

Of course, if a mortal came here, I'm afraid there wouldn't be the feeling of Tang Letian.

Tang Letian wanders in this underground cave. Where the fire shines, snakes and insects often crawl, quickly avoiding and disappearing into the cave.

Tang Letian searched in this cave for a moment according to his memory and found a unique location with fluctuations. Behind it should be the crystal ore vein. This ore vein is relatively small, but it is enough for thousands of people to use it for a period of time.

With these crystal mines, Tang Letian can prepare some necessary equipment for the alchemists of the Demon-Destroying Alliance.

In the future earth civilization, crystal stones are the pillar of the entire civilization and the foundation of the entire civilization. It can be said that without crystal stones, the human race will not be able to defeat the puppet demon, and without crystal stones, the human race will only be in a dominant position.

Tang Letian could feel that the crystal vein was not deep. He took out the short blade and slashed it in the air. The huge stones peeled off from the stone wall one by one, smashing into the groundwater, splashing everywhere.

Tang Letian dug about 10 meters, and the short blade slashed on the stone wall began to spark.

Tang Letian knew that this was the digging of the companion ore. The companion ore of crystal stone was different, but most of them were very hard. These companion ore were also good things. Whether it was used to refine magic weapons or build alchemy furnaces, any item that used crystal stone as its energy was inseparable from the companion ore.

Tang Letian continued to dig, and a companion mine fell down, and a faint light flashed in front of Tang Letian's eyes.

Digged.

Tang Letian dug out a crystal with a faint fluorescent light and put it in his hand to watch it. The purity is OK, so it is okay to use it as you make do.

At this time, a phantom appeared beside Tang Letian, looking at the stone in Tang Letian's hand and asked curiously: "What is this? What's the use?"

Tang Letian didn't find it strange. He was talking about the True Immortal Wufeng. It was obvious that the True Immortal Wufeng did not leave.

"This thing is called crystal, and it is of great use."

As he said that, Tang Letian molten the crystal stone, squeezed the entire crystal stone into a long strip, and then opened the dark grid on his arm guard, where the original crystal stone had been consumed.

Tang Letian pressed the crystal stone into the dark grid.

Then he stretched out his middle finger at the True Immortal Wufeng.

Wufeng Zhenxian frowned slightly: "What are you doing? Your handprint looks very impolite."

A beam of light suddenly shot out from the protective wall and headed straight for Wufeng True Immortal.

The distance between Wufeng Zhenxian and Tang Letian was too close. Even she could not avoid such a close beam of light without any preparation.

This beam of light directly penetrated the divine thought of Wufeng True Immortal, and then set it on the stone wall in the distance and extended it all the way. I don’t know how deep the distance I drilled.

The True Immortal Wufeng will not be injured. With her realm of wandering, her divine thoughts can penetrate everything or be penetrated by everything without any damage. Various attacks basically have no effect on his divine thoughts.

Wufeng True Immortal said in surprise: "What? You actually used only a little bit of true energy to activate such a powerful force?"

After all, it is the existence of the Nascent Soul realm, and you can see through Tang Letian's cleverness in arm protection at a glance.

Tang Letian smiled and said, "This is a piece of equipment I have created, which can be used by any monk. Even monks in the Qi Refining Stage can easily control it. This is a piece of equipment that changes the world and changes all rules."

"Equipment? This name is a bit meaningful. This thing is different from magic weapons."

As Wufeng said, the arm guard on Tang Letian's arm suddenly dismantled it on his own, then flew to Wufeng's arm and tugged it together.

Tang Letian was really shocked when he saw this scene.

This arm guard is actually very complicated. Even Tang Letian tried it many times before he created it. The most important thing is that Wufeng True Immortal silently took away his equipment. He could not resist at all, and he didn't even feel it. When Wufeng True Immortal brought the arm guard in his hand, Tang Letian suddenly realized that the arm guard had been taken away.

From this point of view, it can be seen that if Wufeng True Immortal wants to kill him, Tang Letian, it would be a matter of breathing. Tang Letian was a little scared at this time. Did he deceive Wufeng True Immortal too much? If he fails to reach the level of Wufeng True Immortal's cultivation level in five years, with Wufeng True Immortal's small-mindedness and aggravation, he might be fragmented.

Wufeng True Immortal stretched out his middle finger toward Tang Letian. When Tang Letian saw this, he immediately avoided and shouted, "You can't face people."

True Immortal Wufeng looked at his middle finger and said with some confusion: "No matter how you look at this handprint, you will feel a dirty smell."

A beam of light suddenly appeared on the protective wall of Wufeng Zhenxian, and hit the stone wall with a whoosh and stretched out, leaving a small, burnt, bottomless hole on the stone wall.

"Yes, this little thing is really interesting. If you give the Qi Refining Cultivator equipment, you might accidentally kill the alchemist. However, it is not very useful for the infant."

The wrist guard on Wufeng Zhenxian's arm was disassembled and flew away from his arm.

As soon as Tang Letian stretched out his hand, his arm guard flew back to his arm, and then he clamped it tightly.

"You mean, these crystals are the energy source of this arm guard? If this is the case, can we also create some more powerful equipment? Use 10 times the power of the crystal to bloom the light beam, and that will make it stronger."

Tang Letian nodded and said, "I also have this idea to create a real cannon. Even the Nascent Soul Infant can't stand that thing. It's very useful to deal with the puppet demon."

Wufeng True Immortal suddenly said: "Tang Letian, I know you are the reincarnation of a baby, but who are you reincarnated? Did I know you before?"

Tang Letian quickly glanced at me and said, "It shouldn't be known. When I was reincarnated, many memories were lost. Sometimes a little memory popped up suddenly, but they all met some familiar things and people. I have never had any familiar memories after meeting you. I think we have never seen each other before."

Wufeng Zhenxian nodded: "Don't summon me casually if you're not lucky. If you meet me with a bad temper, maybe I will kill you directly."

Tang Letian shrank his neck.

Tang Letian could hear that Wufeng's True Immortal was scaring him, but scaring was also a warning. With the realm of Wufeng's True Immortal, Tang Letian couldn't take what he said without taking it seriously.

Tang Letian hurriedly said, "True Immortal, please help set a ban to isolate the divine consciousness to investigate, so that the Dao site of our Demon-Destroying Alliance can be placed here without hiding around."

True Immortal Wufeng frowned and said, "You guys have so many requirements."

Then Wufeng's true immortal disappeared without a trace.

But then a ban completely wrapped the underground space, like a huge bubble.

Tang Letian looked at it and found that this ban could last for about a year. In a year, Wufeng Zhenxian would like to ask him to set the ban again.

At this moment, the stone wall on the top of the cave suddenly began to fall, and countless pieces fell into the river.

After a moment, Tang Letian looked up and saw 8 big characters engraved on the top of the cave. Those who follow me will prosper and those who go against me will perish. There are four small characters "Wufeng Zhenxian" next to it.

Tang Letian kept shaking his head when he saw it. Wufeng's true immortal is so fond of a false reputation. He has to make a mark wherever he goes.

However, from this point of view, Wufeng True Immortal is indeed full of love for the eight words "those who follow me will prosper and rebellious against me will perish!"
