The other set was bought for Gu Anlei, but because of her poor physique, he only bought models one through six, spending a total of 500,000 merit points. Although it wasn't perfect, after the genetic modification of models one through six, Gu Anlei's own talent had already reached a terrifying level.

"I'm really looking forward to modifying the Demon God's body!"

Jiang Yuan stared into thought as he looked at the nine gene serums of different colors. These serums were not exactly mature technological products, as they were still full of uncertainties.

Let's begin!

Jiang Yuan took out Gene Agent No. 1 from the container. When he opened his chest, Gene Agent No. 1 extended many tentacles like a bacteriophage and then pierced into his chest, injecting the agent directly into his heart.

"hiss!"

Jiang Yuan took a deep breath, feeling a warm current enter his bloodline, eventually taking root in every corner of his Demon God Body for final genetic modification.

This set of potions is suitable for human bodies. If he takes it with his demon god body, it will inevitably cause great drawbacks, but he has no choice.

Ten minutes later, the first gene serum took full effect, and the demonic runes engraved on every corner of the body gradually became imbued with another kind of power.

"Again!"

Genetic modification is a very long process, but that's for others. For Jiang Yuan, however, drastic measures are the only way to achieve good results.

The second gene serum was also injected into his heart. After the dark blue liquid disappeared completely, Jiang Yuan's body began to convulse uncontrollably.

The Demon God Body's own immune system was activated. It identified these foreign genetic modification factors as invading factors and began to use Jiang Yuan's power to kill the gene-modifying agents.

"Just stay put!" Jiang Yuan's will was extremely firm. No matter how much the Demon God Body resisted, he remained unmoved.

The third, the fourth, ... all the way to the eighth branch, Jiang Yuan finally faced a slightly bigger challenge.

Genes are selfish. The previous gene serums could be considered minor, but Jiang Yuan's actions now directly modify the Demon God Body. How could the Demon God Body be happy about this? Therefore, the rejection reaction caused by the gene's self-protection is unprecedentedly intense.

Jiang Yuan was quite familiar with this situation, because he had replaced the Three Emperors' genes into his body a long time ago. At that time, he didn't even know anything and dared to do this operation. Now, he would not hesitate to use gene serum.

The eighth dose took a full three hours, longer than the previous seven doses of gene therapy.

"call!"

Jiang Yuan exhaled a breath of stale air to adjust his state and prepare to continue with the ninth dose of the medicine. Replacing his original genes all at once now would save him a lot of trouble in the future. After all, if he replaced them now, he could start metabolism tomorrow and complete a complete transformation from the inside out.

"I wonder if this No. 9 potion will be effective!"

Jiang Yuan looked at the last, deep red, blood-like ninth potion. When he exchanged for the ninth potion, Tianfu had solemnly warned him not to use it indiscriminately if he was not a perfect human, and even if he was, he should use it with caution, because the ninth potion itself was unstable.

The No. 9 drug uses a semi-synthetic technology. What is semi-synthetic technology? It means that the No. 9 drug is not simply a laboratory product. Part of its drug components are unknown genes, which are gene pools left on Earth by the Godfall Battle. However, modern technology uses certain methods to screen and combine these gene pools to obtain the optimal gene sequences, and finally, this No. 9 drug, which is not yet fully mature, is made.

"The rich rely on technology, the poor rely on mutation!"

Jiang Yuan had this thought pop into his head, but when it came to him, he not only had to rely on technology, but also on mutation.

"open!"

The No. 9 potion hovered in the air, its red color creating a stunning visual effect. Then, drop by drop, the potion entered his bloodstream, and Jiang Yuan's consciousness began to blur, as if he were falling into a wondrous, intoxicating sensation.

"Damn it, I've run into a counterfeit..."

Before Jiang Yuan could finish complaining, his entire consciousness shrank back into the Soul of Mending Heaven.

The Nine Spirits Bloodline, carrying the power of the gene-based medicine series, roamed within the Demon God's body. Wherever it passed, the Demon God's body underwent slight changes, and even the Demon God's markings, which had once leaned towards demonic cultivation, began to return to normal.

Moreover, the hidden power of the eight gene serums from before suddenly surged forth, turning Jiang Yuan's body into a chaotic arena.

However, in this arena, only those with strong genes can survive.

So, an interesting scene unfolded: the once incredibly lazy Demon God Body took the initiative to compete, and eventually even cooperated with the Nine Spirits Bloodline, with the two joining forces to integrate other weak genes.

He didn't know how much time had passed when Jiang Yuan suddenly had an introduction to the integrated Demon God Body in his mind.

Nine Spirits Demon Body (Human Race, containing a demonic soul): Quality: Mythical, Potential: True God, Passive: Nine Spirits, Active Skills: Nine Spirits Demon Heart, Nine Spirits Demon Body.

Passive - Nine Spirits: Amplifies skills and talents of the nine attributes, increases immunity to damage of the nine attributes, and enhances the compatibility of the nine attributes.

Active - Nine Spirits Demon Heart: Activating the Nine Spirits Demon Heart will grant you half an hour of unlimited divine power, influenced by your bloodline and demonic soul.

Active - Nine Spirits Demon Blood: Under the circulation of the Nine Spirits Bloodline, two extremes are formed. After activation, the attack and defense multipliers are inversely proportional. The multiplier limit depends on the changes in the bloodline and the demonic soul. The current multiplier limit is 22.

A single gene integration brought together the Nine Spirits Bloodline, the Demon God Body, and the True Soul of the Demonic Path. From that moment on, he began to have real confidence.
