Nie Tian didn't think much after listening to Mu Xi's words. The elder should be careful. If something goes wrong, he will lose a lot. Nie Tian knew that without this artifact, his martial arts could not achieve his peak effect.

Therefore, he could only wait for Muxi to start quietly. After a while, Muxi walked to the stove with the Dragon chopping sword and lit the cauldron.

Then the two palms put some energy into the cauldron. Fire is a kind of special material burning, its temperature is very high.

A few minutes later, everyone in the room felt the heat and began to sweat slowly. Muxi looked at the temperature almost, and quickly threw the soul crystal stones from the table. They fell into the Dan Ding accurately.

The purpose of this step is obviously to melt the soul crystal at ultra-high temperature, and then import it into the Dragon chopping sword, so as to make the soul of the sword gain more powerful power.

This process seems easy, but it's a little distracted. When the soul spar is injected, the fire and uneven injection may cause local overheating, and the Dragon chopping sword will be destroyed by high temperature.

Therefore, Muxi is also worried about this. If it's an ordinary sword, it's not very worried, but it's just an excellent sword. It's worth a lot. It's an artifact against heaven.

Once destroyed, I don't know how many souls will go out. Over the years, dragon chopping sword has made great contribution to guarding the dead.

In this way, after half an hour, Muxi began to put the Dragon chopping sword into the charcoal, in order to raise the temperature of the Dragon chopping sword, and then wait until all the soul stones melt, and then inject them into the Dragon chopping sword.

After entering the charcoal pile, the blade of the Dragon chopping sword began to show and became a real sword, which was also the action of the Dragon chopping sword when it resisted burning. At this time, the soul of the sword suddenly felt a burst of heat, looked up and felt the fire burning.

"Master, master, what's the matter? How could it be so hot? "

A burst of sound waves spread to Nie Tian's brain through brain waves. He was stunned at first, and then he continued to listen: "master, I am the soul of dragon chopping sword. Now I use brain waves to communicate with you, and it's OK to communicate directly through the brain."

"Yes

Nie Tian thought about it in his mind, which was equivalent to answering. He was a little excited. "The soul of the sword, you can bear it. It's our need to strengthen the forging of dragon chopping sword outside. Now the Dragon chopping sword is in the charcoal, so you will feel hot."

"Ah? No, it's in charcoal. Will it cook me up later? " The soul of the sword thought and said.

Nie Tian is speechless. It's strange that your soul can still be burned. I feel that there must be a burning, but there will be no burning in the real sense.

So Nie Tian said: "you don't have a body. Where can you burn it? It's just that you have this feeling. If it doesn't get in the way, you can bear it. When the Soul Crystal merges with you, you will become more powerful."

"Wow, I'm so happy. Hurry up. I'll wait. Master, I'll get ready first." Then the soul of the sword disappeared.

Nie Tian wry smile for a while, this also too pull, a soul will feel hot, there is no mistake.

After about half an hour, I saw Mu Xi began to be a little nervous, and the sweat on her forehead slowly seeped out.

A few people on one side also became tense with the atmosphere, obviously strengthened to the high fever stage, ready to enter the integration stage.

After a short time, Muxi took a deep breath, pulled the Dragon chopping sword out of the charcoal, and then quickly put it into the designated entrance of the sword casting furnace.

The next step is to grasp the appropriate temperature, and then slowly open the gate of the space containing the soul crystal. In a moment, the melted Soul Crystal slowly flows into the Dragon chopping sword.

At the same time, Muxi quickly uses two fingers to inject energy into the handle of the Dragon chopping sword. The purpose is to evenly distribute the flowing soul crystal solution to all parts of the Dragon chopping sword. Don't let it be destroyed because of local heat.

At this point, as long as a little inattentive, the temperature will be uneven, eventually leading to failure.

So, Muxi was very nervous at the moment, he even began to lower his breath, trying to keep himself stable. And the beaded sweat on his forehead flowed slowly along his neck.

Nie Tian is more nervous, looking at Mu Xi sweating, he is also worried about whether Mu Xi can withstand.

Half an hour later, suddenly he turned pale. He could only cry, "no, I have too much physical strength to maintain their temperature, but I can't replace them, because you don't know how to balance the temperature."

"What about that?"

Nie Tian's heart is cool after hearing this. Is the Dragon chopping sword going to be destroyed? Is the soul crystal stone that he has been looking for gone?

No, we must not let the Dragon chopping sword have problems. Otherwise, we should fight with Tiandan gate and open the five elements array.Thinking of this, Nie Tian's head began to run at a high speed. All of a sudden, Nie Tian got a flash of inspiration, suddenly patted his thigh and thought, "by the way, why didn't I expect that my physical strength can be restored by running the secret? Can it help people recover? "

This Nie Tian is also holding the attitude of try, although some risk, but this is now the only way, isn't it?

Thinking about this, Nie Tian walked over slowly, and then said to Mu Xi, "master, I have a way. I don't know if it's feasible. Let's try if we want to?"

At this time, Muxi was about to run out of energy, so she quickly said, "if you think it's OK, just try, I can't stand it."

This is the first time that Muxi, as a sword maker for so many years, has encountered the situation that her physical strength is overdrawn. At this time, because the strengthening of dragon chopping sword is different from other artifact, Muxi didn't expect that it needed so much physical strength.

It seems that there are still about 30% to be completed, but he can't do it.

In the past, no matter what sword strengthening was, it only took half of his physical strength to complete. This not only drained her physical strength, but also Mu Xi felt that the more physical strength she consumed in the later stage.

Now he is still worried, even if Nie Tian's method is effective, whether he can reach the end is still a key.

At this time, Nie's palmprint was so strong that he couldn't get up quickly. This time, Nie Tian has to use all his strength. Otherwise, the Dragon chopping sword will be damaged, and that will be the end.

Saw a pure energy suddenly into the body of Muxi, suddenly, Muxi felt a lot of spirit, physical strength in the rapid recovery, which makes Muxi surprised.

The young man in front of us, who he will be and how powerful he is, has only heard that he can transmit strength to others, but he has never heard that he can transmit strength. Obviously, the young man has already done it.

This is also the more and more advanced mental method of Ning Jin Jue. It will be more and more obvious to recover physical strength and heal injuries.

At this time, Muxi was very happy. Now her physical strength has recovered to 7788. As long as she continues to insist, the artifact will be strengthened.

Nie Tian also can see that Mu Xi's face starts to be ruddy from pale, and has obviously returned to normal. And Nie Tian's mood is gradually relaxed, sweat drops down his face, cold Qiuyan on one side looks good is distressed.

However, the situation inside the furnace is not optimistic. Because of the lack of physical strength just now, the temperature obviously began to differ. Therefore, at present, the best way is to reduce the temperature of the relatively higher part. However, how to reduce the temperature is that the fire in the furnace is evenly distributed. It is impossible to change this suddenly.

"No, there's something wrong with the Dragon chopping sword. Due to the local high temperature, the temperature is unbalanced. You can't distribute the soul crystal solution to every corner. In this way, you may destroy the Dragon chopping sword blade. Even if you don't destroy it, the attack power will weaken. Instead of strengthening, it will weaken."

At this time, Muxi frowned and said the situation.

Nie Tian finished listening to Mu Xi's words, frowned, and began to think of a way, this is imminent, can't delay more, his hard work, can't be so wasted.

"So what? Master Muxi. " Nie Tian asked and answered in a hurry, but he didn't think of a way.

"You need to find a way to cool the Dragon chopping sword, and it must be cooled by me. You can't control the position of the sword." When Muxi said this, she felt that she couldn't come up with this method, but everyone didn't want to give up at the last moment.

Nie Tian wry smile, this is obviously impossible thing, how to cool down, and can't be controlled by others. Suddenly a familiar voice came from behind, "Nie Tian, let me have a try!"

Nie Tian looked back and saw Leng Qiuyan slowly come over, carefully walk to Nie Tian's body, and then said, "Nie Tian, do you remember that I absorbed a lot of cold air in my body, if my strength was introduced into the body of master Muxi, and then controlled by him, would it be able to adjust the temperature to balance?

At this time, Nie Tian is very happy. He also wants to think about it. It seems like a good way to say that according to Leng Qiuyan. So, Nie Tian quickly nodded his head happily and said, "OK, Qiuyan, try it. Don't be too nervous."

Leng Qiuyan nodded, and then said to master Muxi in a soft voice: "master, I'll give you some energy later. It contains the ice energy I inhale. Then you can use it flexibly."

Just now, the conversation between Nie Tian and Leng Qiuyan was heard by Muxi. Although he was very surprised, he didn't dare to neglect them at this critical moment.

In a hurry, all of a sudden, Muxi felt a cold energy injected into his body, which made him shiver and almost overturn the Dragon chopping sword.

Fortunately, he was full of determination and quickly stabilized himself.

Now that there is cold, that wood Xi also did not have much time to delay, directly to adjust the temperature, after more than ten minutes of adjustment, the temperature has been basically balanced.Nie Tian looked at Mu Xi and calmed down. He was so nervous that he let go. He wanted to know what this dragon chopping sword meant. Nie Tian's family knows his own affairs, and a lot of his attack power comes from the Dragon chopping sword.
