"This catty of 10,000-year-old stone milk should be enough for the Chaos Divine Tree to give birth to the power of chaos. ”

Back in the advanced cultivation room, Ye Chenfeng immediately took out the 10,000-year-old stone milk that he had traded from Senlei.

Although directly taking the Ten Thousand Year Stone Milk has limited improvement to the realm, according to the previous experience, the Ten Thousand Year Stone Milk can accelerate the Chaos Divine Tree to give birth to the power of Chaos, which is also the real reason why Ye Chenfeng traded the Ten Thousand Year Stone Milk.

Once the Chaos Divine Wood gives birth to the power of Chaos, then he will master a major hole card, even if Sen Lei refines the Demon Heart Crystal and improves his strength, he will not be afraid.

Moreover, Ye Chenfeng didn't believe that Sen Lei had the strength to refine the Demon Heart Crystal in two days.

The magic power contained in the Demon Heart Crystal far exceeds that of the Demon Crystal Bone, and if Sen Lei forcibly refines it without knowing the Demon Heart Crystal, it is likely to backfire and damage the body.

Therefore, trading the Demon Heart Crystal to Sen Lei gave him not a chance, but an unknown invisible bomb.

"Chaos Divine Tree, Devour!"

Ye Chenfeng raised his head and poured a large amount of milk-like, very viscous, and fragrant 10,000-year-old stone milk into his stomach, controlling the rapid devouring and absorption of the Chaos Divine Tree parasitic in his heart.

Just when Ye Chenfeng controlled the Chaos Divine Tree and devoured the refining of the Ten Thousand Year Stone Milk, Sen Lei, who had most of his body soaked in the blood pool, was preparing to refine the Demon Heart Crystal that he had traded from Ye Chenfeng.

"Ye Chenfeng, I found that you are so stupid and cute, you actually traded such a precious energy stone to me, I really don't know how to thank you. ”

Feeling that the powerful magic power contained in the Demon Heart Crystal was extremely beneficial to him, Sen Lei showed a Sen Ran smile, he had no doubt that if he refined these two Demon Heart Crystals, his cultivation of magic skills would be upgraded to a higher level, and his own realm would also be raised to the peak of the first-level Reverse Beast King.

"Whew!"

Time was limited, Senlei did not waste time, took out a sharp dagger, cut his chest, and directly pressed a demon heart crystal into his body.

Contaminated with Sen Lei's blood, the Demon Heart Crystal immediately released a majestic magic power, and the rolling magic power poured into his body like a wild horse, scurrying around his body.

"Yama Jue, refining!"

The reason why Sen Lei dared to directly integrate the Demon Heart Crystal into his body refining was to rely on the Sen Luo Hall to inherit the soul recipe Yama Luo Jue.

He believed that the supreme divine power of Yama Jue could completely restrain the Demon Heart Crystal, refine it, and transform it into energy and melt it into his body.

Yama Luo Jue was running at high speed, and a black vortex appeared in his body, frantically devouring the magic power released by the Demon Heart Crystal.

Seeing that the Demon Heart Crystal was restrained by Yama Luo Jue, suddenly, a terrifying demonic energy gushed out from the Demon Heart Crystal, which instantly condensed into a hideous demon face, directly attacking Sen Lei's soul.

Caught off guard, Sen Lei's soul was damaged, and his head seemed to be cracked, and the pain was unbearable.

"Break it for me!"

The soul was constantly attacked by the demon face, and Sen Lei endured the severe pain in his soul and constantly mobilized his soul power to attack.

With this distraction, the magic power released by the Demon Heart Crystal broke through the devouring of Yama Jue and surged in his body, destroying the meridians and flesh of his body.

"Damn, how could this be. ”

Sen Lei never dreamed that refining the Demon Heart Crystal would be so dangerous, and both his soul and body were injured for a while.

As a last resort, he quickly took out the Demon Heart Crystal that had melted into his body, and fought against the Demon Face gathered by the Demon Heart Crystal with all his might.

When he forcibly eliminated the demonic energy contained in the Demon Heart Crystal and dispersed the hideous Demon Face, a day had passed, and not only did he not improve his strength, but his body was also severely damaged by the magic power released by the Demon Heart Crystal, and there were not a few days before he could recover.

This made him mad with anger, vomiting blood in anger, and his hatred for Ye Chenfeng became even stronger.

There was an accident in Senlei's refining of the Demon Heart Crystal, and the Chaos Divine Wood in Ye Chenfeng's body absorbed a catty of 10,000-year-old spirit milk, but he successfully gave birth to a wisp of chaotic power as thin as a cow's hair.

"Whew, it's finally working. ”

The Chaos Divine Tree successfully gave birth to the power of chaos, Ye Chenfeng showed a faint smile, with this wisp of chaos power, Ye Chenfeng was fully confident that he would kill Sen Lei at a critical moment.

"There is still one day left, which should be enough for me to refine this chalcedony stone. ”

In order to further enhance his strength, Ye Chenfeng took out the chalcedony stone that he had traded from Sen Lei, and used the Soul Devouring Technique to devour the power of the chalcedony contained in it, refining his own bone marrow.

"Well, sure enough, Senlei did something in this chalcedony stone. ”

When Ye Chenfeng was running the Soul Devouring Technique to refine the chalcedony stone, his keen soul perception sensed a wisp of deadly toxin in the chalcedony stone.

If ordinary people are accidentally eroded into the bone marrow by this toxin, their lives will be in danger.

However, Ye Chenfeng, who possessed the Chaos Divine Tree, was not afraid of the erosion of the toxin, and when the toxin hidden in the chalcedony stone burrowed into his body, he immediately controlled the Chaos Divine Tree to absorb it, without causing any damage to his body.

Breaking Sen Lei's secret hand, Ye Chenfeng put his mind at ease, quickly absorbed the chalcedony stone, and tempered his bone marrow.

As a large amount of chalcedony power poured into his bone marrow, Ye Chenfeng immediately had a feeling of being pierced by thousands of silver needles, and a huge pain spread throughout his body.

A large amount of jet-black blood flowed down his open pores, staining him into a bloody man.

The impurities in the bone marrow were constantly discharged, and the bone marrow fused with the power of chalcedony began to form new blood, once the bone marrow of Ye Chenfeng's whole body completed the blood exchange, he would be able to cultivate the marrow refining realm to the consummation realm.

However, marrow refining is the last realm of the Six Veins Shengang, and it is also the most difficult realm, and the energy required exceeds the sum of the first five realms, and a single chalcedony stone can cultivate the marrow refining realm to the Xiaocheng realm at most.

Time passed minute by minute, and Ye Chenfeng relied on his powerful and incomparable willpower to endure the pain of quenching the marrow, running the six veins of Shengang over and over again, refining his bone marrow.

"Dark gold, my bone marrow has finally changed color. ”

The human bone marrow is dark red, and after quenching the marrow, the color of the bone marrow will turn dark gold, and feeling that his bone marrow is beginning to change color, Ye Chenfeng, who has been struggling to endure the severe pain, finally showed a smile.

"There is still half of the power contained in the chalcedony stone, which should allow me to cultivate the marrow refining realm to two percent. ”

Ye Chenfeng took a deep breath, continued to endure the pain caused by quenching the marrow, quickly devoured the chalcedony power contained in the chalcedony stone, and continued to refine the bone marrow.

Finally, at dawn, the chalcedony stone in Ye Chenfeng's hand was shattered, and all the chalcedony power it contained was swallowed into Ye Chenfeng's body and quenched into the bone marrow.

After refining a chalcedony stone, Ye Chenfeng cultivated the marrow refining realm to two percent as he wished, and his pure physical body reached nine hundred thousand catties, coupled with the physical strength of the realm enhancement and increase, his own strength reached an astonishing one million catties, comparable to a fourth-level heavenly beast.

"It's time to go to the martial arts arena. ”

Ye Chenfeng glanced at the faint light outside the window, took a shower in the room, washed off the dirty blood on his body, changed into clean clothes, and went to the martial arts arena.

And in the two days that Ye Chenfeng was in retreat and cultivation, the entire fifth layer of the Killing Tower was rumoring about his peak duel with Sen Lei, and many people directly bet on the outcome of the game.

Although Ye Chenfeng had a great reputation for killing Lion Fire, and was known to more people because of the 300,000 Killing Points bounty, Senlei was the absolute king of the fourth layer of the Killing Tower, and his terrifyingness penetrated deep into the hearts of the fourth-layer martial artists.

Therefore, almost no one is optimistic about Ye Chenfeng, in their opinion, Ye Chenfeng challenged Sen Lei as soon as he came to the fourth layer of the Killing Tower, which was undoubtedly looking for death.
