On the second day alone, new classes appeared on the battlefield. A golem with a long-range bow and arrow appears on the golem's side. Able to kill the little tree spirits that rush at them from a distance.

However, it didn't take long for them to be happy, because a large number of Scorpion tanks also appeared here. The Scorpion Tank's defenses are much stronger than those of the Little Tree Spirits, and the thickness of the wood is very scary.

Destroying a Scorpion Tank is not an easy task, although it takes much longer for a Scorpion Tank to spawn than a Dryant. However, the rear is no longer producing bush warriors at this point, and bush warriors are temporarily withdrawn from the battle sequence. Now a large number of Scorpion tanks have been born, and the number is also very terrifying.

As long as the Scorpion Tank receives more attacks, it will rush out, and then under the calculation method of the Plant Brain, the corresponding artillery will be mobilized to attack the area around the Scorpion Tank.

That's right, as the battle continues, the two-in-one plant brain learns and thinks, even if it's more wooden.

At this time, the plant brain already knows that when attacking, do not use your own target as the target of attack, but attack the surroundings. Perhaps after the shelling, the Scorpion tank will still be able to survive with strong defensive capabilities.

The most important thing is that this attack method can maximize the loss of the opponent's puppet. So the two sides began a battle of abnormal attrition of each other, and there was still no way to break the deadlock.

On the side of the Maro Kingdom, all kinds of combat fortifications are becoming more and more perfect. From the rear, it is clear that the magic tower has been built. Once the mage is stationed, the tower will unleash terrifying powers. The Maro Kingdom built so many magic towers at one time, and it seems that the entire kingdom's treasury has been moved.

In fact, they didn't know that it was precisely because of the system on their side that all the nobles of the Maro Kingdom were resisting them with all their might. Everyone knows that there is no such thing as a nobleman in the Sacred Tree Realm.

Those who have a noble name just a little more privilege, a little more respectable status, that's all. They are high up, but they are not willing to give up the power and territory in their hands.

So in this battle, the nobles from all over the Maro Kingdom can be said to have someone who has made a strong contribution and gone all out. The kingdom of Maro is united as one, and it is unprecedentedly united. This situation made the Maro royal family cry and laugh.

If they had been able to do this for the sake of the kingdom before, I am afraid that Rusyala, and even the other kingdoms around them, would have become part of their Maro Kingdom long ago, and this kind of thing would not have happened today. But even if they go all out like this, the war can only be defensive, it can only be stalemate, and this has been done to the best.

They were preparing in the rear, and Chi Nan was not idle. After receiving the news, Chi Nan knew how to solve it.

If you can't see the enemy, then you can install eyes, and if you have eyes, you can see them.

As for the eyes, there was no way for Chi Nan to make them before, but now it's different. Isn't there a monitor, the plant brain can read and understand the meaning of the various pictures in the monitor, so isn't this thing a ready-made eye? Moreover, if you want to upload some pictures with the monitor, the most convenient way is to read the real picture with your eyes.

So Chi Nan began to study and experiment with the freshly baked display. At the same time, through the variant of the nerve vine, artificial modification of animal eyeballs began to be carried out for research.

Eyeballs are not as complex as brains, so in less than a day, Chi Nan completed the imitation. Two days later, the artificial eyeball was basically made. After the third day, Chi Nan finally revised the research to what he needed.

It's the size of a little finger, but it's not a simple eyeball. There is a hard film on the surface, which is as hard as ordinary steel. And the eyeball inside is not a whole eyeball, but is made to look like an insect compound eye.

There are many small eye lenses inside, and the whole eyeball is protruding, and it can see everything around it in a large area, and can see the entire battlefield from close to full angles. Moreover, with the analysis of plant brain, the field of vision can be easily utilized.

The connected display is for soldiers to use, through adjustment, you can see the details of any angle and any place on the battlefield, which is convenient for the command to control the overall policy.

"Haha, as long as we have this eye, then our plant weapons can see the real picture. No longer only has the previous sensing ability, even the puppeteer of the Maro Kingdom has no way. ”

"It's great that it worked, and I don't have to continue the stalemate. Hemira said with a smile.

Sophia pursed her lips: "First of all, the puppeteer is not from the Maro Kingdom, but a classification of mages, this classification is the best developed in our Rusyara Kingdom, but now it is picked up by the Magic Association." ”

"Second, I'm afraid it's not easy to make this eyeball, do you want to use it all over the army? ”

Seeing Sophia's two fingers erected, Chi Nan stepped forward and gently held it in his hand: "The first one is that I said it wrong, but it's okay, don't care about these details." As for the second point, this eyeball is bronze-level, of course, it can't be made by the whole army, as long as it is placed on the airship and tank. ”

"Through the plant brain, all plants are basically a whole, and as long as one is seen, it is equivalent to everything else can be seen. "Chi Nanke is very confident in this.

The analysis and calculation ability of plant brain is better than that of a computer, and some basic calculations and controls are much more powerful than humans. In particular, the plant brain, which is united together, is simply a huge computer group.

"Well, that's fine. Sophia nodded slightly, no more doubts.

"Besides, whoever told you that those low-level plants won't be able to sense low-level golems. ”

Chi Nan smiled strangely in the puzzled eyes of the two of them: "Just before, one of our boring subordinates researched a plant that can mimic the eardrum. Using this, it can be used as a plant ear. ”

Chi Nan took out a thin film of something: "See, this is it, through air vibration and analysis, plants can have strong hearing." And the level is not very high, just add the plants. ”

This thing, in essence, is not even at the level of black iron, and Chi Nan was also taken aback when he heard the report of the plant brain, he really didn't expect that someone would study this kind of thing. Sure enough, developing a territory is not something that can be done by oneself.
