"Tucker, fly closer, scan it and see if there's a core. ”

After saying a few words, Xu Sheng recovered a little, endured the discomfort, and instructed Tucker to fly closer.

"What is the Spirit Core?"

Tucker asked, did as he said, increased the power of the electromagnetic spiritual force field, and probed the spiritual electromagnetic force into the mouse's body. This has a maximum range of 1.2 meters, so there is no need for a puppet to hold on to the target.

"A small thing, is the condensation of a lot of psionic energy...... Can you see what's going on inside it?"

What the spiritual force field scanned, Xu Sheng didn't know.

"Yes. ”

"What do you see?"

"Some different colored dots of light, clusters of light, and some strange things. ”

"Those points of light, clusters of light, are psionic energy?"

"Yes. ”

"Is there a large amount of spiritual energy that gathers and condenses?"

"It doesn't seem to be there, it's all scattered. ”

"Those strange things, are they the heart, the blood vessels, the cells or something?"

"What is the heart, what are the blood vessels, what are the cells?"

“...... We'll talk about it later, now you start collecting these psionic powers. ”

After a while, Tucker said, "Your Excellency, it's done." ”

"How much psionic power?"

A small part of this collected spiritual energy is injected into the spiritual arc reactor to generate electricity to make up for the consumption of reserve power, and most of it is injected into the core of the primordial tire and converted into growth energy. However, in the information of the primary fetus, there is no change in the value of growth energy...... The magnitude is too small.

“...... I don't know. ”

Well, can't be too demanding of a five-year-old.

"Okay, Tucker, let's keep fighting! You will observe the living rats and dead rats with the electromagnetic spiritual force field, they have different physical states, and after getting acquainted with them, you can accurately determine whether they are dead or still alive. At the same time, pay attention to whether there is a spirit core, I have a lot of use. ”

"Yes, Your Excellency. ”

Soon after, a second mouse appeared, slightly larger than the previous one. Having learned his lesson, Xu Sheng instructed Tucker to strengthen his dodge.

It's not that hard.

Looking at the output power, the speed of the puppet is between 7 and 36 meters per second. The speed of the rat per second, which used to be about 8 meters at the time of the outburst, and even now that it is strengthened, it is generally no more than 15 meters, and the puppet can run over it.

However, the power of the energy ray moved Xu Sheng.

It's too weak.

It can cause a thin blood hole, and it should not be deep, but it stimulates the rats to squeak wildly and chase endlessly. After more than a dozen hits, the latter lay down and did not die. The puppet flew close and struck it twice in the head before turning it into a corpse.

You can't do that!

Whether it is the burst speed or the excitation of energy rays, it needs to output electrical energy with high power, which is actually more expensive. In this way, the collected psionic energy may not consume as much electricity as it does - after the reserve energy drops, most of the collected psionic energy will be preferentially filled into the reactor to generate electricity.

"Tucker, we have to change our tactics, and the next time we fight, fly over and choke it and shock it. ”

"Your Excellency, aren't you afraid?"

"I'm not scared...... Anyway, just do it. ”

Dolls are Xu Sheng's biggest reliance now, so he has a ruthlessness in his heart, and has decided to follow him for a long time, guide him to grow, and let the doll improve as soon as possible. At this moment, electric shock is the best tactic, and it is necessary to overcome the psychological effects such as fear and disgust, and weakness is just waiting for death.

The puppet has the speed to crush the mouse (unless the opponent's speed changes), and when it encounters the third one shortly after, it flies over so smoothly, and at some point suddenly bursts into speed, and catches it at once.

Then, electric shock!

Dead, dead.

In the sewers, sometimes two or three of them appear together, so Tucker adopts a double-kill strategy, grabbing one and then flying over to press one.

After killing 6, the spirit core has not been found, but the growth energy has changed, increasing by 0.1 degrees.

The unit of "degree" is based on the setting that the spiritual energy that can generate 1 kilowatt-hour of electricity in the spiritual arc reactor is set at 1 degree of spiritual energy generated by putting it into the primordial tire.

In this way, you need to kill about 60 to have 1 degree of growth energy. To upgrade the 50 degrees of the level 1 body, you need to kill 3,000 of them.

Not much...... Right?

Come on!

As the exploration continued, Xu Sheng's psychology improved a lot, and the trembling feeling gradually disappeared.

The ecology of the sewers is also gradually emerging, first of all, rats are not as many as expected, they are slightly sparse, they will hunt their own kind when they are hungry, and secondly, mosquitoes and some kind of carnivorous black beetle are active.

The insect is elongated, six-legged, and has double pincers on its tail. The largest is knuckle-sized.

Kill people when they see them.

But the harvest of psionic energy is too slow, and there is not a single spiritual core, which makes people a little irritated.

A rat is choked again, and the puppet violently outputs electricity.

But after ten seconds, Tucker shouted, "Your Excellency, it's not dead yet!"

It is not surprising that many people have taken the action of using electricity to kill rats, and it is true that many of them have been killed by placing wires and turning on electricity, but there are also a small number of rats that have successfully gotten rid of them after being electrocuted, which may improve their resistance to electric shocks. Also, some abilities are resistant to electric shocks.

"Is it so tenacious?"

Xu Sheng was surprised, "Then press it against the side wall, continue to electrocute it, and then clench your fist with your other hand and hammer its head!"

Bang, bang......

The puppet's fist was small, but it was better than metal, and after more than ten punches, there was a click, and the rat's skull shattered and died.

The surprise came, when Tucker collected the spiritual energy, Xu Sheng felt that the spiritual energy had a "surging" trend, and the growth energy that was finally transformed was 0.4 degrees!

Terrible!

This is clearly a mutant rat!

However, there is also no spirit core.

"Tucker, well done! This is a mutant rat with strange abilities, and accidents can occur in battle, so be a little vigilant. Well, go ahead. ”

"Roger!"

Tukchon replied with a twisted sound, and continued to fly forward with a body of filth, grabbing, and lightning, leaving a few corpses every other way.

Rats multiply quickly, and if you want to get rid of them completely, you'll have to invest a lot of resources in renovating the sewers and clearing the city of clutter. Few cities dare to make such a bold effort, and most of them clean up on a small scale and on a small scale, and put forward higher requirements when developing new urban areas.

As for the means of poisoning, after three years, their resistance to poison is already very strong, and the changing toxins make them more likely to mutate.

So, it didn't take long for the puppet to encounter a second mutant rat. It has sparse hair, tumors, pus, and is extremely disgusting. Its abilities are most likely related to poison and disease, but it doesn't have the ability to be experienced by Iron Puppets.

It's dead.

Go on!

At home, Xu Sheng's body lying on the bed once again changed like last night. After he had been attached for a while, wisps of spiritual energy began to seep into his head.

After the revival of the Heaven and Earth Vitality, in fact, many vegetative people woke up, and it was the spiritual energy that infiltrated and repaired the damage in their brains. Now that Xu Sheng has withdrawn his consciousness for a long time, it is like forming an empty pool, and the spiritual energy of the outside world is like water, which naturally fills in!

It's just that the filling speed at this time is far less than last night.
