While the others were temporarily isolating Remas, Chi Nan didn't change his policy in the slightest. With the continuous fighting, the territory of Remas has basically returned to its previous calm by this time.

On the occasion of the arrival of spring ploughing, Chi Nan began to organize the civilian planting of the entire Ruimas. If you use your own improved seeds, the yield will definitely be greater. And everywhere there are manors centered on the mother tree of the home. The jujube trees are abundant in these estates, and life is better now than before. Civilians who have experienced the disaster again easily accepted the leadership of Chinan.

Civilians are as simple as that, whoever can give them a better life, they will support whomever they want.

As for the former aristocracy, who knows who they were. Especially those nobles who took refuge in the bugs and put the beetles in, after propaganda, became the object of disgust and spurning of the people.

In order to deal with the bugs, Chi Nan began to carry out targeted modifications to his plant weapons. The best way to deal with bugs, of course, is those beetle toxins, but the previous toxins are still not enough.

After Chi Nan broke through the silver, he had the ability to mutate in a directional way, so he made these toxin plants into enhanced mutations. Eventually, two new toxins were selected from dozens of mutated toxins.

A toxin, a poison gas that, as before, is able to volatilize quickly. But the evaporation time is longer, the range is larger, and the effect against bugs is stronger. The damage to humanity itself is almost gone.

There is no need to worry about being exposed to toxins for a long time, which will also cause harm to the person itself. Chi Nan directly replaced all the beetle poison bombs with this new toxin. Along with it, Chi Nan also made a large pea cannon.

This kind of pea cannon was deliberately enlarged by Chi Nan and turned into a shape like a rocket, the shell was larger, but the range was closer. But the shells used in it are all this kind of toxin shells.

On the battlefield, this kind of thing works even better for infantry than pneumatic guns and tanks, because it is more flexible.

The second toxin mutates and becomes not volatile, but will adhere to the surface of the object, but the toxicity of the beetle is even stronger than the first, which is an adhesive toxin.

This toxin appeared, and Chi Nan immediately used it in melee combat. Soldiers each have a copy that they can apply to their weapons to increase the damage to beetles.

This is not the most critical, the most critical thing is that Chi Nan has added this toxicity to some of the bush warriors. Previously, Bush Warriors could only kill beetles by spinning with their ultimate, attacking continuously, or hitting vital points with a pinprick in the past. But now you don't need to, just wave it casually and you can hurt the beetle.

This toxin, which the bush warriors themselves secrete, is then naturally applied to the leaves and needles. As long as the strong beetle toxin comes into contact with the blood of the beetle, the beetle will die within a short time.

Because of the use of this new toxin, the beetles in the three underground labyrinth areas are dying and injuring faster and faster. In a short period of time, most of it has been cleaned up by Chinan, and it seems that the entire underground labyrinth area is about to be cleaned up.

Similarly, this adhesive beetle toxin, Ikenan also applied it to the surface of ordinary artillery shells. The airship's cannons now fire shells with this special venom.

This venom is of no use to ordinary people and creatures, so the effect shown by the airship is still no different. However, after this cannon shell hits the beetle, as long as it can be injured, it can basically kill the beetle.

In addition to the transformation of the toxin itself, Chi Nan also transformed the spider tank. In the past, the spider tank, with a few legs like maces, was covered with flying sand and rocks, and the ground was full of messes.

Later, Chi Nan thought of a new method based on the principle of spike telecontraction, so the spikes on the legs of the spider tank became a shrinkage type. When you usually walk, you don't stick your spikes out, so you can walk on the normal path without destroying the road. In those places that are difficult to walk, the spikes will stick out to improve the grip.

Using the instinct of the plant brain, this spike can also control the length of the spike, and it is not necessarily completely unfolded as long as it is stretched out. After the transformation, the Spider Tank's damage to the ground was finally eradicated.

Moreover, this mace-like spider leg can also play a huge role on the battlefield. When Chi Nan attaches the adhesive beetle toxin to these spikes, the Spider Tank becomes a massive killer on the battlefield.

Once, when dealing with beetles, a spider tank formation directly stretched out its spikes, and without using shells, it just walked over. After walking by, all the beetles were pierced with spikes and covered in holes.

Although beetles have strong defenses, most of them are only injured and do not die, but after the toxin penetrates deep into the body. These beetles just hold on for a while and then die cleanly. Since then, this new method of fighting has become the main means used by the Spider Tank to deal with the beetles.

The Spider Tank has also completely become one of the main armies in the north against the beetles.

The toxin-based changes have turned the war contrast between beetles and plant weapons upside down. This didn't change until they encountered some bronze beetles.

The higher the beetle's level, the more resistant it is. Bronze-level beetles are already very resistant to this toxin and will not die for a short time. However, in the face of the terrifying number of enemies, there was still no wave.

Chi Nan was even sure that even if a silver-level beetle appeared, it would be impossible to be completely immune to this toxin, and a large number would have a great impact. Thus, the horn of the counterattack on the north sounded.

While several other fortresses were still re-establishing their defenses, Giant Wood had already had a surplus of troops and began to attack north. By the time several other fortresses had regained their offensive capabilities, the Giant Wood City side had already regained a large amount of land. Chi Nan also relocated a large number of civilians from Remas to settle down there.

Because the population of Remas is getting smaller and smaller, the south still thinks that its side is becoming more and more dangerous.

In the beginning, there were indeed some beetles near the Blackstone Fortress that came to attack. But after two times, the ones that come and attack again are not beetles. Rather, it is the plant weapons that some experiments in Kenan have failed.

On the one hand, it was sent here to be destroyed, and on the other hand, it was also to create the illusion that beetles frequently attacked the Blackstone Fortress. Kea never dreamed that his intelligence department would send him such a false piece of information.
