After a long time, Xuanqi walked out of the depths of the cave, and then poured out a pile of garbage from the portable space in Yechen's surprised gaze, well, garbage!

"Master, this is ......" Looking at the pile of ores and materials on the ground, Yechen looked up at Xuanqi in confusion.

"Didn't I say that the armor soul can only show its value after returning to the underworld, and now these things are for you to use to build the Horcrux Kai. After giving a faint glance at Yechen and explaining, the latter lowered his head and began to find the materials he needed in the pile of ore on the ground.

Looking at Xuanqi who was burying his head in jingling bells and shining on the materials, Yechen pulled the corners of his mouth speechlessly, he was not surprised by this, but surprised when Xuanqi had so many things, judging from the other party's depths, these ores have been piled up in it, but he didn't see it last time, but, before he could figure it out, the latter's next sentence gave him the answer.

"Playing Lao Tzu, it's all broken copper and iron! Taiyi, you can do it, you really can, Yechen, you wait here, I'll find someone." After the irritable words, Xuanqi's figure dissipated.

Looking at Xuanqi who disappeared, Yechen raised his eyebrows, the feelings were all scavenged from Taiyi, and looking at Xuanqi's expression, these things are still useless garbage, are they really garbage. Looking at the unknown ores and materials everywhere, now Yechen is the first two big, and he can't wait for Xuanqi to come back for a while, the former simply sat down and tempered his body to start a boring time.

On the other side, looking at Yechen who was refining his body, Jin Ling's eyes flashed with a hint of determination, he looked down at a blood-red mark on the palm of his hand, the corners of his mouth raised slightly, and after a wicked smile, he returned to normal, and looked at the pile of minerals that Xuan Qi called broken copper and iron boringly.

I don't know how long later, a dull explosion directly woke Yechen from meditation, and after opening his eyes to see the scene in front of him, he was stunned for a moment, and then burst into laughter without any image.

"Hah...... Master, you, what are you doing here? This hair, and your face, are black like this......" What caught Yechen's eyes was Xuanqi's face that had been blackened by carbon more than ten degrees, and an explosive hair that seemed to have been cultivated by a wild boar, and there was still green smoke on his head from time to time.

Hearing Yechen's laughter, Xuan Qi glared at the other party, spit out a puff of white smoke from his mouth and shook his head.

"If it weren't for the fact that you were practicing, did you think Lao Tzu needed to refine this thing in person, damn it, I haven't practiced for too long, and my hand feels rusty, and I almost blew myself up. With that, Xuan Qi turned around and slapped away the pile of ashes as high as a hill behind him, revealing a dark Qikai shirt with a faint coercion inside.

After complaining in his heart, it was obvious that it had been blown up, Yechen's eyes looked behind the other party, and after seeing the pitch-black shirt clearly, the former's eyes suddenly lit up.

"It's ......"

"The Qi Kai that helped you refine it, it's okay, it's okay, it looks like this is a success, otherwise, this piece of Nine Heavens Meteorite Iron will be scrapped, and it will be difficult to find another piece. Hearing Yechen's question, Xuan Qi didn't look back, just looked at the Qi Kai over and over again, and after a long time, he breathed a sigh of relief, explained lightly, and at the same time turned around and threw the Qi Kai in his hand to the other party.

"The main material is the Nine Heavens Meteorite, the strength and toughness are the highest standards in the human world, among which there is also a point of anti-magic stone, which can make up for the lack of magic resistance, but the forbidden spells should not be hard to resist, add a little 10,000-year-old ice ice pith, it should have been able to use a better ice heart, but the old man said that it was used up, although it was not as good as the ice heart, but the ice pith can also strengthen the ice ability of the beast after you possessed the body, and added a little blood essence stone and obsidian, which strengthened the strength of the original Nine Heavens meteorite a few points, and then the scorching Brahma stone, which can make you not feel hot in an extremely hot place, but there is a Tianji who adds it to this stone, which is equivalent to not adding, There are eight beast cores, but the resources are limited, there is only one divine beast core, the fire core of the twin flame dragons, and the others are all high-level spirit beast cores, but there are really few spirit beasts in the spirit system, so there is only one low-level, these can greatly improve your combat power, you can collect it when you have time in the future, and then replace it all, so that your combat power can be improved again, as for now, let's return to the underworld first. ”

Listening to Xuanqi's analysis, Yechen only has one feeling now, that is, he has heard a lot, but he still doesn't understand, he hasn't heard of what kind of stone or stone, what kind of ice pith and ice heart, the only thing he can understand is the last sentence, let him pay attention to collect the core.

Shaking his head bitterly, Yechen picked up the Qi Kai that the other party threw to him, but suddenly found something.

He won't!

Looking at the instrument Kai in his hand for a long time, Yechen looked up at Xuanqi speechlessly, touched his nose and said with some embarrassment.

"Master, that, return to the underworld, I won't. ”

Hearing Yechen's words, Xuan Qi was stunned for a moment, and then closed his eyes speechlessly.

"Summoning your soul. Then enter the contract of the soul into the machine. ”

Hearing this, Yechen didn't say anything more, but summoned the unknown instrument soul in his body, and at the same time re-recalled the contract that had been integrated into the body, and put it into the black weapon Kai in his hand, the moment the contract entered the Qi Kai, the Brahma King who had been suspended in front of Yechen since it was summoned seemed to have been summoned by something, and floated towards the Qi Kai on the side, and when the body of the instrument soul completely poured into the Qi Kai, the light on the body of the instrument soul gradually faded, and at the same time, the Qi Kai itself also underwent a huge change.

Originally, there were no patterns on the body of the original ink-black Qi Kai, but at the moment when the machine soul merged with it, a black rosette covered with the entire blouse appeared, and at the same time, the original waist-length blouse also became a robe, flanked by inverted barbed shoulder pads, covered with strange black lines, and the mechanical texture that originally looked very cumbersome also dissipated in an instant, turning into a soft velvet like ordinary clothes.

"True, Instrument Soul, Unknown Rank, Brahminat's Upper Vestment, Return to the Underworld, Instrument Spirit, Unknown ......"

Before he could take a closer look, a sudden text appeared in Yechen's mind.

"Unknown machine spirit? and, this is it?" his eyes widened in disbelief, he couldn't believe that returning to the underworld was so easy, and besides, what did the last machine spirit mean by the unknown in that words?

On the other side, looking at the suddenly changed instrument soul, Xuan Qi's eyebrows wrinkled suddenly, and this time, the familiarity brought to him by that instrument soul was even stronger.

"Damn, King Borneo, King Borneo, this name, this appearance, so familiar......" Xuanqi, who had been thinking for a long time and had no clue, couldn't help but feel irritated in his heart.

"Master, is this done?" didn't notice Xuanqi's strange expression, and now Yechen just wanted to know if his return to the underworld was completed.

Hearing Yechen's question, Xuan Qi came back from his thoughts and looked at the former.

"No, you're one step away from signing a contract with him again, smearing the blood of your fingertips on it, and completing the blood traction. After shaking his head and negating the other party's words, the latter explained.

Hearing this, Yechen didn't talk nonsense anymore and directly cut his fingertips, smearing the blood overflowing from his fingertips on the black robe in front of him, and suddenly, the connection between the sea of consciousness and the disappearance of the soul in front of him was established again.

"True, Instrument Soul, Unknown Rank, King Borneo Jacket Contract Signed, Covenant Master, Yechen. ”

Looking at the extra information in Zhihai, Yechen breathed a sigh of relief.

On the other hand, Xuan Qi fell into deep thought again, and suddenly, his head was raised suddenly, and his eyes were full of disbelief.

"King Borneo, it's her!" Xuan Qi's body trembled obviously, a glimmer of fear flashed in his eyes, and after calming down, he turned his head to look at the night that looked down at the soul that had returned to the underworld.

"I wanted you to take a piece of soul to cover your luck, but I didn't expect you to sign this, King Borneo...... Is it providence?" muttered softly, and Xuan Qi pursed the corners of his mouth.

"Yechen, you should remember one thing, don't use this artifact soul until you have to do it as a last resort, unless you have found all the other Bharat's suits, then you can use it wantonly, otherwise, the former can only bring you death. ”

While hearing Xuanqi's suddenly solemn words, Yechen was stunned for a moment, and then looked up at the former in confusion, but after seeing the solemnity in the other party's eyes, he pursed his lips and nodded, although he didn't know why, but since Xuanqi didn't say it, he wouldn't ask more, anyway, the other party wouldn't hurt him.

Looking at Yechen who nodded, the latter was stunned for a moment, but quickly reacted back, with a hint of approval in his eyes, and nodded at the former.

"Put it away, you must collect the souls of other Brahmanas, as for this blouse, when you have time in the future, change the original eight cores on it, it is best to all of them are ancient beasts, only the cores of ancient beasts can give full play to the strength of this soul." With that, Xuan Qi waved his hand and said no more.

Listening to Xuanqi's instructions, Yechen nodded again, but then he thought of something and turned his head to look at Jin Ling on the side.

"Master, what about Jin Ling, can you make a weapon for her?"

Hearing Yechen's sudden question, Xuan Qi was stunned for a moment, followed the other party's gaze at Jin Ling, frowned slightly and shook his head, "I'm sorry, refining the weapon Kai for you just now has consumed a lot of my energy and aura, and it is difficult to refine another one." ”

"But, isn't it necessary to use the instrument soul to cover the medicinal fragrance on her body?

A rhetorical question made Xuan Qi stunned again, considering that he was not incapable of refining another instrument Kai, but, because Jin Ling's instrument soul was a true red armor, although he looked at the former, but it was what Tsukasa Ling said, so he had to guard against it, and for the sake of Yechen's future safety, he would say that he no longer had the energy to refine, but now after Yechen mentioned it, he remembered the original intention of letting Yechen and them go to the instrument soul mound, and found a weapon soul for Jin Ling to cover the medicinal incense, and Yechen's armor and soul was secondary, but now, the situation is just the opposite。
