What is different from the rest of the secret palace is that the protective secret array is not opened, and the door d is directly open. Instead, a large chimney is built on one side, and fireworks are constantly coming out. From time to time, the sound of "ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding ding

"Master, we are here." Qian Lei and Fengcheng said respectfully in unison.

There is no sound inside.

"Master, Qian Lei, Fengcheng is here to worship!"

There was still no sound inside, only the "ding ding dangdang" sound came intermittently.

The two smiled awkwardly at Chen Feng: "The master's temper is a bit strange."

After a while, there was finally a response inside. This was a hoarse and old voice: "Come in."

In the middle of the secret palace is a huge stove. The stove is extremely ordinary, with a blazing fire. It is surrounded by various hammers, pliers, clips, anvils and other tools.

What surprised Chen Feng was that the master beside the stove was not the strong or unfathomable appearance he imagined, but a thin old man over 60 years old. He held a black hammer as big as an exclamation mark with his thin arms and slowly hit him. It can be seen that it was difficult for him to raise the hammer head in his hand, with his steps floating, and sweat as big as beans fell on his face, as if he could fall down at any time. But the old man did not fall down and still kept his natural frequency of beating.

Under the hammer is an iron block that Chen Feng can never guess what shape it will be in the future.

The old man didn't say anything, Qian Lei and Fengcheng stood solemnly on the side. Even Qian Tong, who was always reckless, didn't say a word.

"I brought what I want." The old man finally stopped the hammer, glanced at Chen Feng, let out a light whisper, and then asked the two of them.

"Bring it." As he said that, Qian Lei took out a red iron piece from his arms. This iron piece was much smaller than Chen Feng's one, so it could be hidden in his arms.

Lieyang Iron! Chen Feng immediately recognized what this thing was.

"The weight is OK, and you are also determined. According to what I said before, I will take one-third of this piece of Fiery Sun Iron to add to your secret weapon, and the rest will be left to me as a reward."

"nature."

"Okay. You are waiting aside, and you need to inject secret power later." After saying that, the old man took out a sword and a sword from the secret mansion.

This sword and one sword only had its first appearance, and there was no special thing.

The old man took out a dark pliers and pulled two pieces from the Lieyang Iron. Only then did Chen Feng notice that the old man's strength was unexpectedly great. Chen Feng himself had tried Lieyang Iron, but he couldn't be beaten up by himself. This image was completely different from what he had just now.

Next, the old man attached the two pieces of Fiery Sun iron to the sword and stuffed them into the stove. Then he took out two pieces of white charcoal and put them into the stove. The temperature in the stove immediately became hot.

The old man pointed to the three holes in the stove and said, "You three just need to instill secret power in it. The speed does not need to be too fast, it is equivalent to using the secret technique of fire bombs."

"I understand." Qian Lei, Fengcheng and Chen Feng each took a hole and began to input secret power into it.

It's strange that this stove looks extremely ordinary, but Chen Feng's secret power will be immediately sucked away as soon as he left his body.

The three people carefully controlled the output of secret power as required. The old man used a huge tong tong to not rotate the sword.

A quarter of an hour later, Fengcheng was the first to be able to hold on, so he took out the secret stone and started to absorb it. After a while, Qian Lei also took out the secret stone and looked at Chen Feng at the same time: "Can Chen Feng still persevere?"

Chen Feng didn't want to be too shocking. After all, even if the secret power of the fire bomb secret technique is very small, if it is used continuously for so long, the secret power of ordinary secret soldiers will not be able to keep up. Even though his body is full of secret power, he still took out the secret stone.

In this way, the three of them kept changing the secret stones in their hands, and gradually their faces were pale, and sweat was flowing out from their foreheads. Of course, Chen Feng's appearance was pretending.

Finally, the old man said "Okay", which made the three of them feel relieved and quickly sat down to restore their secret power.

The sword secret weapon is out! The Fiery Sun Iron has been completely integrated into the secret weapon.

The old man picked up the smallest hammer and kept beating it. Gradually, the hammer became faster and faster, and finally turned into a afterimage. Chen Feng could no longer see the hammer. What is most renowned is that the landing point of the hammer is different almost every time. Without decades of dipping, it would be impossible to achieve this step.

When the hammer finally fell, the old man was slightly tired and said expressionlessly: "Okay."

When Chen Feng looked at the sword again, there was still no light, and he still looked very ordinary. Even the weapons in the hands of the thugs were slightly worse than those of the thugs.

"Is it done?" Qian Lei hesitated and asked.

"Just go back and find your master to carve the secret array. As for what secret array is engraved, it depends on your preference."

"It doesn't look like a secret weapon." Qian Tong couldn't help but say.

The old man snorted, "Is it because I am afraid that the opponent will not see that his secret weapon is powerful? The secret weapon is used to kill people, not to show off." After that, the old man picked up the knife casually, and gently knocked it against a piece of bluestone on the ground. The bluestone shattered in response to the sound. There was no trace left on the back of the knife.

Then, the old man took out a lot of hard objects to test the sharpness of the sword. After a try, everyone was surprised again. The sword almost reached an extremely sharp and invincible level. No matter how strong or hard it was, it would be left with a hole by the blade and sword edge.

Finally, the old man solemnly took out a few extremely tiny pieces of silver metal from a box. The metal piece looked very luxurious and shone with a faint luster. The old man scratched it a few times with a sword. This time, the silver metal piece was not damaged as much as the previous items, but left a scratch. Of course, the sword was unscathed from beginning to end, no matter what the sword was in contact with any object.

The old man explained: "These metals are called Yueyin, which are materials used to refine secret treasures. They are very tough. The pair of sword secret weapons I have created will not be deformed even if they are against ordinary secret treasures. For the upper and lower grade secret weapons, you can directly cut them hard."

Qian Tong opened his mouth wide and was shocked. Qian Lei and Fengcheng were overjoyed and thanked him repeatedly.

"Give me the Lieyang Stone, I will help you make this secret tool. The transaction is fair, and there is no need to thank you."

Qian Lei and Fengcheng came to thank Chen Feng again: "I don't know what Brother Feng wants to pay."
