Shi Lei Yin recalled the origin of his part of Lemut's spider tooth gene. That was when he hadn't come to the Polar Continent yet, and was still on the Pan Continent. The group was attacked by a pitch-black Lemut spider, and as a result, they devoured the Lemut spider and obtained the genetic sequence.

Although Shrayin can confirm that this is not some kind of trap, the fact that the Lemut spider, which is famous for its vegetarian diet, will leave its permanent habitat, the Lemut vine, and run into the forest, and actively attack and hunt other creatures is enough to explain the problem of this Lemut spider.

Carefully recalling the original memories that he had almost forgotten, Shi Leiyin was shocked to find that the Lemut spider at that time exuded this black qi now. At the same time, the Lemut spider showed a very similar situation to the clawed lizard that pounced on him when he had just fallen into a killing state and still had a little sense. Especially the black gas that wraps around the head, and the scarlet eyes.

As soon as this situation was confirmed, Shi Leiyin hibernated all the genes of the Lemut spider, and then actively separated them. Genes that have been phagocytosed and fused are usually dormant, and unless they have a more powerful equivalent gene, the existing genes will not be eliminated but will become gene imprints and remain in the cells after dormancy. Genes in a dormant state do not manifest themselves in any way, nor do they wake up due to special circumstances such as injury or loss of consciousness. Unless Shi Leiyin falls into an instinctive rampage, and all genes are automatically liberated, the dormant state is the safest way to preserve it. However, in Shi Leiyin's opinion, although when he fell into killing mode, Lemt spider teeth were in a state of gene activation, but since there was a risk of causing consciousness to fall into killing mode, even if the dormant state was not necessarily the safest mode, the best way was to actively isolate and directly reject this risky gene.

Active detachment is an ability that Shi Leiyin discovered by chance after reaching a certain level of control over his body. Although it is a natural ability, Shi Leiyin was still surprised and very happy at that time. After all, the reason for the active isolation of the gene sequence at that time was that he accidentally absorbed a very disgusting ability - self-explosion. At that time, Shi Leiyin was too diligent in collecting biological genes, and as a result, he accidentally absorbed an insect-like creature called a blastworm by Shi Leiyin. This creature is about the level of a first-class monster, and its strength is not high, and it looks a bit like a cabbage worm that is three times fatter, round and fat. Burstworms are parasitic creatures, generally parasitic on some large herbivorous monsters, which is why Shi Leiyin accidentally absorbed its genes. After completing the Devouring Fusion, Shi Leiyin discovered the existence of the Burstworm on the corpse of the herbivorous demonic beast. And that's why Shi Leiyin knew that this bug would self-destruct. Because when those bursting worms, which were about the length of an adult human finger, came out of the corpse of the demonic beast, they exploded immediately. The splash of liquid melted the entire body of the beast into a puddle of green water. Then, something even more terrifying happened, from this puddle of green water, countless bursting insect larvae appeared, and then absorbed the entire puddle of green water at a speed visible to the naked eye, and then burrowed into the ground and disappeared. Apparently, this self-detonation is a form of reproduction by blastworms, in which after the death of the parasitic subject, the mother is sacrificed and then rapidly reproduces larvae that are able to move quickly, in an attempt to replace the new parasitic subject.

After imagining the situation where he also exploded into a ball of green water, and then turned into countless tiny individuals, Shi Leiyin only thought about how to reject this gene. Although this gene is almost one of the best life-saving abilities of phagocytosis fusion organisms. But Shi Leiyin still instinctively rejected, when human instinct and slime instinct conflicted, Shi Leiyin found that he had the ability to actively isolate some genomic sequences that he did not want to exist.

However, even if genetic isolation is to be carried out, Shi Leiyin still needs to conduct some experiments. Absorbing some of the magic power on the cage, the two low-level clones were split by Shi Leiyin. One of them has been injected with all the isolated Lemut spider genes, and is in a non-dormant state. The other is a doppelganger that splits again after the completion of active separation, and most of the genes are in a non-dormant state.

Shi Leiyin did this, firstly, to see how those unexplained black qi induced the killing state, and secondly, to check whether his other genes were also contaminated with black qi. The super infection ability of the dragon virus made Shi Leiyin have to be on guard.

Stopping to replenish energy, Shi Leiyin began to carefully induce the clone. The killing state directly acts on the consciousness, and the doppelganger itself is not conscious, which means that even if he activates the black qi on the doppelganger, it is still possible to make the consciousness fall into the killing mode and thus affect the body.

Shi Leiyin didn't know how to induce the Lemut gene sequence with black gas on the doppelganger, so he could only try little by little. First, the gene sequence was completely activated, making it completely dominant, but even if the doppelganger had completely changed into the shape of a shrunken Lemut spider, the black qi still only existed in the inside of the cell, faintly and emergingly. So Shi Leiyin had to try to increase the amount of consciousness that entered the clone, and pay close attention to the changes in the black qi. However, even though Shi Leiyin had sent more than eighty percent of his consciousness into the clone, the black qi still did not change in any way.

This was actually expected by Shi Leiyin, because Shi Leiyin's previous state itself was carrying the Lemut spider gene in the activated state. Even if all consciousness enters the doppelganger, it is only the same state as the previous oneself.

In the end, Shi Leiyin could only try a relatively dangerous possibility. After withdrawing most of his consciousness, he began to indoctrinate the doppelganger with negative thoughts of killing, anger, and so on.

Shi Leiyin's attempt was successful, and almost at the moment when these ways of thinking entered the clone, the black gas erupted violently as if it had been splashed with fuel. Shi Leiyin, who was paying close attention to the clone, immediately cut off the consciousness connection with the clone.

The entire body of the Lemut spider state doppelganger began to glow with black gas. Shi Leiyin discovered the specific composition of this black qi. Previously, when the black qi was attached to the gene sequence, it was too small, and this kind of near-molecular-level existence Shi Leiyin naturally couldn't feel its composition. But now that the black gas had erupted in large numbers, although it was also very threatening, it gave Shi Leiyin a chance to perceive its specific composition—the black qi composed almost entirely of negative emotions.
