A few days later, Lu Kun's body recovered to its peak, his internal organs had been tempered many times, and his life strength exceeded the extreme of his current realm, and the damage caused by the spiritual shock wave was limited.

On the contrary, in the refining process, the consumption of essence blood is not small, but fortunately, he has stored a lot of it this year, and after replenishment, he can also cope with the next refining.

And Hong Yuntian's qi and blood magic power, in this land of the magic pool, also recovered very quickly.

At this point, everyone looked into mid-air, where only three things were suspended in mid-air.

The five-element blade body intertwined with silver blood light and multicolored spiritual light, the demon knife body exuding a purple-black glow, and the lilac blood sac inner tank full of spirituality.

"Hei Yan, your main task is completed, then stay in shape, and wait for me and Brother Hong to successfully complete the next step, and then come to refine the knife handle. ”

The three of them nodded, and sat honestly in the spiritual qi pillar.

At this time, Lu Kun stretched out his palm, and a large amount of silver blood gushed out from his fingertips, like countless long threads, weaving between the Five Elements Knife Body, the Demon Knife Body, and the brand-new inner tank.

His blood only temporarily connected these parts, and when it was in the late stage of bone transformation, he used the new blood that could transform bone to refine and partially transform the blood inside into bone, and the sword body of this war treasure would really take shape.

The biggest purpose of this is to make the formed Tongtian Battle Treasure equivalent to a part of the physical body, in addition to the magic energy that can circulate in it, and the body can cultivate its own physical source power, it can also radiate on it.

Back then, in the Holy Demon Sect, Lu Kun injected a large amount of essence blood into the Demon Dragon Blade, temporarily regarded it as a part of his body, and through the special magic pattern of the Demon Knife, he radiated two million catties of source power, which was the only way to use the extremely condensed Demon Yuan Qi Blade.

That time, it mainly relied on the power of one yuan, the Void Condensing Yuan Divine Power, and the Demon Dragon Blade only helped the Yuan Qi condense the knife shape and activate a blockade technique similar to the Yuan Shen Chain.

And the other people control the Demon Dragon Blade with the help of the magic power containing qi and blood to activate the magic intent inside, so as to play such a magical power.

If Lu Kun succeeds in smelting the Crazy Demon Intent, he can not only let the Instrument Spirit Mind attract the Demon Yuan Qi Sword, but also use the physical body source power to assist.

Moreover, his frenzied demonic intent is different from the intent of slaughter, and it is likely that he has taken into account the attributes of the demonic spirit vitality at the same time to control the two heaven and earth vitality.

If on this basis, he exerts the magic power of one yuan power, and the power of the Heavenly Battle Treasure will definitely exceed that of the Demon Dragon Blade.

Thinking in his heart, the thing in front of Lu Kun had already taken shape.

It was a huge blade that was five feet long, close to his height, and its blade was extremely broad, without sharp blades, and exuded a heavy aura.

It's not so much a knife as a giant piece of iron.

At both ends of the dark silver blade, there is a hollow with the thickness of two palms, and there are flashing smart thoughts inside, and the inner tank of the machine spirit is inhabited.

Lu Kun waved with one hand, the thick blade fell on the palm of his hand, holding a huge weapon, and his appearance looked a little strange.

He felt the weight of tens of thousands of catties in his hand, and said with a straight expression: "Brother Hong, we are ready to start." ”

Hong Yuntian nodded, walked side by side with Lu Kun, walked to the central demon pool, and then he jumped lightly and jumped directly into the real demon pool.

Lu Kun stood outside, turned his wrist, handed the other end of the blade to the past, and said with a solemn expression: "Brother Hong, you are responsible for conveying the true demon intent, and I will activate the frenzied intent in the bloodline." ”

Hong Yuntian held the end of the blade with both hands, and said with a solemn face: "Okay!"

Lu Kun said again: "Xue'er, you are the body of the machine spirit, you will not be attacked by the will of the true demon like the divine soul, the blood smelting is equal to the second refining of you and the inner tank, if you succeed, you will become a combination of will and machine spirit." ”

"Buzz ......"

The blade trembled, and a heavy roar came out.

Lu Kun took a deep breath, the blood in his body tumbled, and a bloodline aura exuding a powerful coercion rose up, and in his hands holding the blade, clumps of dark silver blood condensed and injected into the gap.

Thanks to the bloodline separation method researched by him and Hong Yuntian, Lu Kun was able to extract the origin of the true dragon's bloodline, and naturally he could also isolate the frenzied meaning of the bloodline of the giant ape.

The extremely frenzied will rushed into the blade along Lu Kun's bloodline and essence blood.

He has a top-notch demon beast bloodline, although the madness contained in it is strong, but after all, he has not entered the god transformation stage, and the bloodline will is a rootless source, and it will disappear when it is used up.

Fortunately, the Body Refining Pavilion has a special mountain of oaths, and the stone fetus transformed by the Lingming predecessors will gradually produce a sense of madness, and the lost thoughts can be replenished.

As for Hong Yuntian on the other side, the lower half of his body was soaked in the purple-black pool water, his hands were stuck at the end of the blade, and his palms gradually softened into black liquid, and after a while, the entire forearm fused to form a black flesh ball, which was blocked at the knife edge.

At the same time, strange lines appeared on the surface of the body, like some kind of totem, and the cruelty in the True Demon Pool surged towards his hands along these lines and injected into the blade.

The inner tank inside is like a special flesh and blood furnace, Lu Kun's essence blood, Hong Yuntian's flesh and blood essence, conveying two special willpower into the furnace.

While controlling the bloodline, Lu Kun communicated with the machine spirit, and according to the method of the Holy Demon King, in the special pattern of this inner tank, the two minds were in contact little by little.

......

I don't know how long it took, the aura and demonic qi in the Rongyuan Demon Cave suddenly tumbled violently, and circles of black and white light emerged from it, and the terrifying vitality was permeated all around.

"Manifestation of Vitality!"

Heiyan Daojun stared at this scene with wide eyes, the Yuan Infant in his body trembled slightly because of this coercion, his cultivation in the late Yuan Infant was still like this, not to mention Qin Yushu and Yu Lin.

So the three of them leaned closer to each other and joined forces to sacrifice a shield to protect their bodies, and the pressure of the surrounding vitality was reduced a little.

The aura of vitality manifested around them converged towards the location of the demon pool, and the white spiritual vitality surged towards Lu Kun, and the demon vitality was absorbed by Hong Yuntian's body, and the two vitality continued to drill into the blade body through their physical bodies.

As time passed, the aura of vitality became thicker and thicker, even submerging Lu Kun and Hong Yuntian's bodies.

At this moment, the thick and huge blade trembled violently, and two special thoughts rose from it, and the power of crazy and brutal thoughts intertwined.

Hong Yuntian was immune to the true demon's intent, but he couldn't resist other thoughts, and a layer of pale silver crystal armor quickly appeared on the surface of his body.

The three of Qin Yushu, who were not far away, even sacrificed their soul protection beads, but even so, their divine souls were under great pressure.

"Boom!"

After a long time, it seemed that in an instant, in the center of the Rongyuan Demon Cave, a special thought full of crazy anger suddenly appeared.

More demonic vitality converged in the direction of the demon pool, and in this dim demon cave, a glimmer of dazzling light appeared.

The black and white demonic spirit vitality fused with each other, and in the outer door of the heavy blade, a pale golden thick sword light appeared.

As the vitality converged inward, the sword quickly condensed, and the power of the vitality in the demon cave rose wildly, gradually gushing out a breath like destroying the world.

Under this invisible pressure, the Rongyuan Demon Cave rumbled and shook, and the walls were forbidden, dimming at a speed visible to the naked eye.

Qin Yushu and the three of them were all terrified, this coercion completely exceeded their imagination, and the mana frantically shrank into the dantian yuanying, and the shield outside the body became more and more dim.

"Black Flame Daoist, is there a way to help resist it, this power is too terrifying, mana can't be mobilized at all, if it continues like this, we are likely to be hit hard. ”

When Heiyan Daojun heard Qin Yushu's transmission, his face was solemn, and he directly activated the origin of the Yuan Infant, and the shield outside the three of them blessed a layer of black flames, protecting them with the help of the power of different fires.

Still, from the fluttering aura and flickering flames, it was clear that they couldn't hold on for long.

"Click......"

At this moment, a crisp sound suddenly came from the roar of the cave's vibration.

Everyone looked intently, only to see a crack on the thick and heavy knife body, and at some point, the crazy and angry thoughts seemed to have been vented and became more intense.

On the side, Lu Kun's eyes were red, his face was full of anger, and his body trembled, and on the other side, the blood crystal armor outside Hong Yuntian's body was also rapidly dimming, and they seemed to be forcibly supporting it.

And the first crack on the knife body seemed to have a head, like a spider's web, and spread rapidly......
