All the Linhai Kingdom has been searching for the mother plant of the disease and insects, but nothing suspicious has been found. Instead, many mutated sea monsters that have never been seen before have been found. Most of the time, they have to explore the seabed under the pursuit of mutated sea monsters, which is slow and dangerous. Now with the addition of the demon hunting system, the probability of finding the mother plant has been greatly improved.

Si Xu did not lead the team out again, and completely handed over the task of finding the mother plant to Lu Yu, and he took Lu Jiu to act alone.

The two of them took a flying vehicle to move on the seabed. Since they had the energy stone for making energy capsules, Si Xu was more confident in the use of flying vehicles. He could make energy capsules by himself, and he didn't have to worry about running out of energy.

The two have been searching on the seabed for several days. The detection range of the Demon Hunter System is very wide, and the speed of the aircraft on the seabed is not slow. They have already circled their own waters and found no mother strain. Other coastal countries have not found it in their own waters either. There is only one possibility, that the disease and insects are brought out by marine life, and the real mother strain is likely to be hidden in the sea where no one has set foot.

This guess was soon confirmed. The Demon Hunter System tracked the infected marine life and tracked it to a bottomless trench on the seabed. Even though Lu Jiu is a mermaid, she dare not go to such a bottomless trench.

[The marine life that comes up from the trench carries disease and insects in its body. The mother strain should be down there. Do you want to go and take a look? They

must go down. There must be a lot of dangerous marine life hidden in this dark sea trench. Even if they know there are dangers, they must explore it clearly, otherwise the whole ocean will be destroyed by pests.

The headlights of the aircraft broke through the thick darkness and slowly dived down.

The aircraft has its own sensing system. From the display of the console, Jiu Jiu can see that there are many large red dots swimming slowly in the trench. Those are giant sea monsters hidden in the trench. The outlines of the red dots are strange and bizarre. Even if Jiu Jiu has not seen their true appearance, he knows that they look very arbitrary.

Si Xu controlled the aircraft to carefully avoid those large red dot outlines. The aircraft's speed became slower the further it went down.

"Is this it?" Lu Jiu suddenly pointed at a red outline on the monitor.

The huge outline was very similar to the green creature that Si Xu had pulled out, except that the one in the trench was very huge. The original filaments on this monster had turned into something comparable to tentacles, so dense that it made people's scalps numb.

Si Xu stopped the aircraft and did not continue to dive. He turned off all the lights. In the dark trench, silver-green tentacles danced with the sea water. The large area of ​​silver-green looked very beautiful. In fact, Si Xu and Lu Jiu, who saw this scene, all had their hair standing on end.

They did not approach it rashly. They used the aircraft's built-in camera to take pictures of the scene in the trench and quickly returned.

Lu Jiu asked the system: Did it detect anything?

[It is full of diseases and insects. Be careful when destroying it, and don't let its juice leak out.]

Lu Jiu: Is there any good way?

[Artificial destruction is very dangerous. Once the tentacles are cut off, the juice that flows out will be full of diseases and insects, and all marine life will suffer.]

Now at least a small part of the mutant seafood is infected. If all marine life is infected, there will be no hope for mankind.

Lu Jiu and Si Xu returned to the South China Sea and handed over the coordinates of the trench, as well as the photos and videos taken, to the person in charge. They decided how to solve it. This matter concerns the safety of the entire earth. Countries big and small will participate and overcome this difficulty together.

The mother plant of the disease has been found, and those who are still looking for it at sea can come back.

Si Xu accompanied Lu Jiu to a rehabilitation hospital. The Demon Hunting System had just come back, and Lu Jiu wanted it to take a look at these "awake ones". It didn't matter whether the Demon Hunting System had a solution or not. It would transmit the test results to the Demon Spirit Main System, and the Demon Spirits would provide a solution. When he

saw the awake ones again, they were more natural than the last time he saw them.

Lu Jiu walked along, and the awake ones were busy with their own things, reading books, watching movies, playing games, and sleeping. There was also a awake one who was chatting with a nurse. The nurse's face was stiff, and it looked like she was going to run away at any minute.

In the end, they were no longer as empty and dull as they were at the beginning, and they became more and more like humans.

Lu Jiu found a sober person who was sleeping and asked the system to check his brain.

The system no longer requires magic points for everything. It knows that Lu Jiu will not let it sleep due to lack of magic points. When magic points are really needed, Lu Jiu will provide them. The system does not need to worry about collecting magic points.

After the inspection, even the demon hunting system was surprised.

[This kind of disease is quite interesting. Even my inspection was almost fooled by them. They pretended very perfectly.]

Lu Jiu: Can they be saved?

[There is no hope. What can be saved if the brain is gone?]

Lu Jiu is very worried. These sober people can run, jump, talk and laugh now, just like normal people. Many of their family members think that they have recovered. If they died suddenly, the family members would be the first to not accept it and would definitely make a fuss.

Moreover, it sounds bizarre that the pests eat the original brain tissue and then disguise themselves. It is hard to explain and it is difficult for the public to believe.

Rujiu took the Demon Hunting System to see the infected people who were still going crazy. This period is called the early infection stage by researchers, and the awake ones are in the middle infection stage. Since the middle infection stage is hopeless, is there still hope in the early infection stage?

[There is hope, but it is too difficult. It is too difficult to exceed the reproduction rate of the pests and eliminate them all.]

Rujiu simply said: You transmit the data here to the Demon Spirit Main System, and let them help think of a solution.

The Demon Hunting System is also very simple-minded. Since there is a big boss system over it, it does not use its brains and directly throws the problem to the big boss to worry about.

The big boss system is worthy of being a big boss. The solution was quickly fed back to the demons.

They can be saved in the early stage of infection, but they need to change their minds to save them in the middle stage.

The treatment method in the early stage of infection is also very simple, kill them with medicine.

When there are pests in the body, the first reaction is to take anthelmintics, but these pests not only reproduce quickly, but can also combine, separate and mimic. Once they mimic human tissues, if they are not careful, the pests will not be killed, but humans themselves will be killed by the medicine. This is also the reason why countries have not yet developed effective medicines. This kind of pest is really difficult to deal with.

The demons may have been stuck for too long and don’t want to wait a moment. They don’t need Lu Jiu to urge them, they will rush to solve this matter.

The solution was given, and soon the formula for the killing potion was also sent over. The Demon Master System even asked the Demon Hunter System to urge Lu Jiu to solve this problem quickly so that they could find an energy depot.

The Demon Hunter System dutifully converted it into the formula of the Earth plane. As long as the potion was produced, the early infected people would be saved.

The Demon Hunting System also knows that time is life, and it transforms the formula as quickly as possible. Unfortunately, there is a kind of magic material that cannot be replaced on the Earth plane. In order to make this killing agent, Lu Jiu and Si Xu have to go to the Demon Sea plane to find this magic material.

When Golofitz heard that they were going to the Demon Sea plane to find magic materials, he was so angry that he almost drilled out of the plane cracks.

What are you still looking for? What do you want in the universal warehouse? Just take it directly from the warehouse, as much as you want, for free!

So, Lu Jiu got a batch of magic materials without spending magic points.

Si Xu personally made a batch of killing agents and went to test the drugs accompanied by researchers.

The researchers were actually very confused. They studied day and night, but the results were not as fast as a non-professional.

The insecticide has been tested briefly in the research institute, and its killing effect on pests is surprisingly good, so we dare to use it on the infected.

There are only ten people in the first batch of people who use the drug, and we will wait for their results to judge whether the drug is effective.

After the injection of the insecticide, the infected people struggled very hard, and they struggled for almost an hour before they slowly calmed down. Their eyesight returned to normal, and they could speak, but their mental state was very poor and their bodies were very weak.

While killing pests, the insecticide also had an impact on the human body.

In the subsequent inspection, the pests were not found again.

The pests were really killed.

Lu Jiu handed over the formula of the killer to the research institute, and also handed over the magic material that was not available on Earth, and asked them to arrange people to make the killer. Lu Jiu and Si Xu did not mix it.

What they needed to solve was the problem in the sea. How could they destroy it without harming the mother plant?

After the location of the mother plant was announced, other countries also sent people to check it out. After returning, they all shook their heads and said that they couldn't do it. Not to mention that they couldn't destroy the mother plant, even if they could destroy the mother plant, it was a question whether they could defeat the mother plant.

Si Xu said: "I actually have an idea."

Everyone looked at him.

Si Xu only looked at Lu Jiu, "If my ability is strong enough, I can separate the mother plant from the outside world, drag it out directly from the trench, and then send it to the crater, throw it into the magma and burn it."

The idea is good, but it is too difficult to implement.

Lu Jiu understands what Si Xu means by "strong enough ability". He wants to use advanced gene enhancers.

The system became a mouthpiece between them.

Lu Jiu: No, your body is not strong enough. Forcibly using it will be life-threatening.

Si Xu: I have been eating magic meals, and my physical foundation is good. Nothing serious will happen.

Lu Jiu: I can't let you take risks. Since you have the ability, then mine can do it too. I will use the water prison to drag the mother plant up.

Si Xu: What I mean is that with your help, otherwise it will be difficult for me to complete the whole thing by myself.

Lu Jiu hesitated, and simply said: Ask Golofitz if there is any safe and effective method.

Golofitz: "..."

Thank you so much, what safe and effective method, just tell me if you want the medicine!

So before Golofitz got the energy depot, he lost another medicine to enhance his body strength.

Golofitz issued an ultimatum.

[After solving the mother plant, I hope you will find the energy depot immediately! ]

Even with the medicine to enhance his body strength, Si Xu was still very dangerous when using the advanced gene enhancer, which scared Lu Jiu and kept harassing Golofitz, asking him to find a way to reduce Si Xu's pain.

Golofitz was so annoyed by Lu Jiu that he simply cut off contact and turned a blind eye.

In Golofitz's view, pain was nothing, as long as he was not dead, it was not a big deal.

After Si Xu completed the full awakening of the Demon Clan genes, his eyes and blood turned completely silver. Before the Demon Clan genes were fully awakened, Si Xu's pupils would only turn silver when he used the Demon Clan bloodline. Now his pupils are silver in color as usual.

Si Xu became a real Demon Clan, and the aura around him became mysterious. No one knew how strong he was.

Just when everyone was ready to go out to sea to drag the mother plant out of the ditch, Lu Jiu and Si Xu received bad news at the same time.

Vera and Song Mozhi were missing.
