After Cold Tide left, Mu Ge said to Xin You: "Alchemy, alchemy, this kid of Cold Wave is not only unable to see the depth in terms of strength, but also knows a lot in other aspects, and I can't understand him more and more." ”

Xin You also said: "It's really a little incomprehensible, I won't be surprised if anything happens to him." ”

Mu Ge thought for a while, and suddenly asked curiously: "Xin You, you said, if you start a life-and-death battle with this guy Cold Wave in the wild, are you sure to defeat him?" ”

Xin You thought seriously for a while, shook his head and said: "I don't know, the cold wave is too mysterious, I don't know what hole cards he will have, there is too little information to deduce." ”

Mu Ge said again: "So, plus that dragon cub, the two of you deal with him, are you sure to defeat him?" ”

Xin You thought seriously for a while, and still smiled bitterly: "I don't know, I don't know." ”

When it comes to Xin You's strength, there is a little red dragon to fight with him, even if he is against Yu Geso, who has the defensive forbidden spell 'Jingyan Shield', Xin You will not be intimidated, and he is sure that he will win the battle, but if the enemy is a cold wave, Xin You is really bottomless in his heart.

"I think this cold wave guy's previous life was either born in the flood plane or in the god and demon plane, and only in this super demon plane will a monster like him be born, what do you think?" Mugo Dao.

Xin You nodded in agreement, and said slowly: "I think that Hanchao is very likely to be a certain demon god in the god and demon plane......"

About 2 hours later, the cold wave returned to Xinyou's private territory.

He began to set up his small private workshop in the corner of his private domain.

Large and small utensils, crystal bottles, glass pipes, alchemy equipment, etc. were piled up on the ground.

Metal blocks, unknown minerals, unknown liquids, and unknown powders as auxiliary materials are scattered everywhere.

In the gray mist, one by one the Yin soldiers were summoned by him, and under the control of his mind, they began to help him sort out the scattered objects on the ground.

Nearly half an hour passed, and these things scattered everywhere and piled up like mountains were put away in different categories, and all kinds of equipment were assembled, and from a distance, it looked like a small laboratory that was very common in the 303rd universe space-time.

During the whole process, Xin You and Cold Wave were watching curiously.

After putting all kinds of materials in large and small utensils, and adjusting the instruments slightly, the cold wave began to make a fire in a special stove, and the fire was made with something called a fire stone, which was expensive, and when it burned, the flame was smooth, and the flame was not red, but dark cyan.

The Fire Yuan Stone is one of the specialties in the Heavenly Dao Base, and it is said that the flames produced by the burning of the Fire Yuan Stone are comparable to the True Fire of the Earth Veins in the Xiuzhen World!

The cold wave also stuffed another thunder rough stone with a faint glow of electricity on the surface into a groove of the instrument.

The alchemy equipment began to operate, and in those large and small vessels, the metal pieces began to melt, and various materials began to mix in different proportions, and magical reactions continued to occur, until about 5 minutes later, drop by drop of pale golden liquid was generated, dripping into a specially made silver vessel engraved with runes.

This golden liquid looks pure and flawless, without the slightest impurity, like the top elixir jade liquid, and even exudes a refreshing fragrance.

"This smell, this smell is really good, this color is ...... I really want to go over and take a sip and get a taste of what it will be like. Mugo watched from a few meters away, and after taking a deep breath, couldn't help but swallow his saliva.

Cold Wave just stared at the row of complex instruments in front of him, and didn't even look at Mu Ge, he said calmly: "This is called melting spirit liquid, it is used to melt the innate spirit treasure, the innate spirit treasure is very tough, you must prepare a special liquid to smelt it, do you want to drink a little?" ”

"That...... Don't be, I was just joking. Mugo hurriedly covered his mouth.

Cold Wave nodded and said no more.

When the golden melting liquid dripped into the special silver vessel, Han Chao took the full basin of golden liquid aside, took out another special silver vessel, and continued to take the drops of golden melting liquid as he said, "Mu Ge, give me that fragment of your innate spirit treasure." ”

Mu Ge hurriedly took out his Space-Time Blade fragment, and with anticipation on his face, handed it to Cold Wave.

Cold Wave took it and threw the fragment of the Blade of Time and Space into the golden molten liquid that filled the vessel.

Xin You took a few steps closer and looked forward, and he found that after the Blade of Time and Space was placed into the golden vessel containing the melting spirit liquid, it was like a black stone being put into the clear water, without any reaction.

No, if you look closely, there is still a reaction, on the fragments of the Blade of Time and Space, small bubbles began to emerge, and there were more and more small bubbles, gradually covering the surface of the fragments of the Blade of Space.

Obviously, the Space-Time Blade fragment is reacting with the Space-Time Blade Fragment, but this reaction is quite slow, and looking at this trend, it should take a long time for the Space-Time Blade Fragment to completely melt away.

Sure enough, Han Chao spoke: "If the Melting Spirit Liquid wants to completely melt the fragment of the Innate Spirit Treasure, it will take about 3 days, you don't have to wait here, Xin You, just leave your Seraphic Sword fragment here." ”

Xin You nodded, he took out his Seraphic Sword fragment from his storage ring, and placed it next to Cold Wave, after that, he and Mu Ge retreated.

Mu Ge began to practice his concealment and attack skills, while Xin You continued to practice the killing move 'Sword Roaring Thunder' in Sword Mastery.

The space of the private territory was limited, and in order to avoid disturbing the cold wave, Xin You and Mu Ge both moved their cultivation place to the other side of the private territory.

A day later.

The air was filled with the sound of wind and thunder, and a dark red flying sword shuttled flexibly in mid-air like a fish, if there was nothing, it was like an illusory illusion, and it was difficult to be locked.

It's done!

When the thunder dissipated and the flying sword trembled and landed on Xin You's shoulder, Xin You wiped the beads of sweat oozing from his forehead with his hand, and a smile appeared on his face.

After his unremitting efforts, the first killing move in "Sword Fighting", 'Sword Roaring Thunder', was finally completely practiced by him!

The prompt sound from the Heavenly Dao sounded in his ears on time: "Congratulations, your Sword Control has reached the mastery level!" You have taken another step forward on the road to the strong. ”

'Sword Roaring Thunder' was completely practiced, allowing Xin You's "Sword Technique" to break through from the rough level to the proficient level.

Xin You's eyes froze, and he once again entered a state of relaxation, this time, he did not use the killing move 'Sword Roaring Thunder', the flying sword cut the air in mid-air again and again, causing ripples visible to the naked eye to appear in the air in front of him.
