They don't have any qi in their bodies, all the qi is gathered in their heads and circulates in their heads.

Is this what makes their heads so powerful that they can even break through stone walls?

Another round of impact, the crack was even bigger, and it could even be stuffed into a finger.

"Hurry up, blow up those big guys with a grenade." I don't know who roared, and countless grenades were thrown at the side of the round-headed giant rat.

The successive explosions sent the round-headed rats west, but some of them were very close to the stone wall, and the explosions were also near the stone wall. The stone walls, which were already cracked, were even more overwhelmed, and the cracks were large enough to fit into the palm of your hand.

Fortunately, the round-headed giant rats were all wiped out.

But Liu Fei was surprised inexplicably, the round-headed giant rat turned out to be a high-level fierce beast, which made his head a little short-circuited. Because the Rat King he killed was also a high-level fierce beast, there should not be much difference in the strength of the two. So...... Judging from the principle of the animal kingdom, these round-headed giant rats are also rat kings?

This is definitely impossible, a rat colony naturally has only one rat king, then! Liu Fei's previous judgment was wrong, and inside the intricate rat hole, there were more and more powerful giant rats.

Liu Fei was taken aback by his thoughts and hurriedly left them behind. At this stage, the rat tide makes the Anqing City military a little difficult, if there is more......

The cost of bullets is intense, but the giant rat can see the end. In the darkness, there were several pairs of big eyes staring at this side.

These giant rats are as big as elephants and look like mountains of meat. He ran extremely fast, and in the blink of an eye, Ben Darkness rushed to the stone wall, and opened his mouth to bite.

Those soldiers were obviously no match for the giant rat, whether it was the giant rat's attack, it was the huge body. Being touched next to each other may cause the soldier to fall into a piece.

This kind of giant rat is the last time Liu Fei met the 'Rat King' in the rat tide, and now it seems that he is just a 'rat general'. There was no rat general in the rat tide last time, and judging from the performance of the soldiers, it is likely that they have never encountered it, but I didn't expect so many to appear this time, and the round-headed giant rat is also a high-level fierce beast.

Compared to the round-headed rats, these rats seem to be weaker, and despite their large bodies and thick fat, they are also fatal when they are hit in the head by bullets.

The second wave of rats quickly receded, leaving behind many larger giant rat corpses, but also the lives of many soldiers.

This time, the soldier did not easily step out of the stone wall, and stood straight on the stone wall, holding the gun in his hand without the slightest relaxation, and held on until dawn.

Many of the soldiers collapsed from exhaustion, but some officers urged them to pick up the corpses.

The bodies of the dead soldiers will be buried on a hill not far from the barracks, where gravestones are neatly arranged.

The top brass of the military were speechless around a square table!

"What's wrong? It's all dumb, let's talk about it, how to deal with it! "The response that Master Li said is naturally to deal with the next rat tide.

The rat tide comes once a month, and this time there are such large casualties, and the military losses are immeasurable.

"I thought that the five-meter-high fence would stop this group of rat cubs, but I didn't expect it to be." A deputy division commander shook his head.

"Lao Fang, I didn't tell you to shake your head, I wanted to find a way. Almost every rat tide we consume millions of ammo, so soon, we run out of ammo. What can be done to stop the rat tide? ”

The deputy division commander was silent!

"The only way to do this is to continue to raise and strengthen the wall." A brigade commander spoke.

"That's one thing, this time it's ten meters high and five meters thick. Brigadier Chen, it's up to your soldiers to do it! Do it now! ”

"Yes!" Brigade Commander Chen stood up and commanded loudly.

Senior Commander Li turned his head, "That was just one aspect just now, there are many variants in this rat tide, what do you think?" ”

"That kind of giant rat with an exposed skull is very powerful, and its head can actually break through a wall, and a weapon should be developed against this giant rat."

"Then you can do it!"

After the nervous assignment, Division Commander Li rubbed his temples. Now the military in Anqing City is seriously lacking in intelligent talents! What has just been discussed is a palliative, not a cure.

However, to cure the root cause, it may be necessary to use missiles! Bombed the rat's nest with one shot, wouldn't it be a disaster?

Belch...... This method seems to be more violent and mindless! The current Anqing City is fed by the rat plague, and if there is no rat plague, these people may all starve to death.

In short, left and right are not!

But Liu Fei and the others ate hot rat meat, to be honest, Liu Fei hasn't eaten a serious meal since he became a monster. The first is that all the organs in his body are made by him, and it is just a façade, and the second is that he does not feel hungry.

However, when the food entered his body, the cells in his body seemed to come to life, and they rushed frantically towards the food that had slid into his esophagus. Fortunately, Liu Fei controlled it in time, otherwise he would have staged a big change in front of others.

The cells quickly absorb energy from the food, and before a second arrives, there is no residue left in the food that has just been eaten, as if it has not been eaten.

Liu Fei was stunned for a moment, and hurriedly ate another mouse. The same is true this time!

It's like having hundreds of millions of mouths all over your body, and the owner of each mouth is a big stomach, and you can't feed it.

With more than a dozen giant rats in a row, Liu Fei still didn't have the slightest sense of satisfaction. The other soldiers looked at him with some surprise, they had never seen anything so thin and so edible.

Liu Fei also realized that something was wrong, and left pretending to be full.

Liu Fei still didn't feel any change in the lower abdomen of more than a dozen giant rats, which surprised him very much. He felt it was time to study his body, he wasn't just not like it now, he wasn't a human at all.

What exactly is the ace elixir, Liu Fei still doesn't understand.

The hospital in Anqing City was very sparsely populated, and Liu Fei found a more sophisticated instrument, a microscope.

This thing was put in a pile with a pile of dried blood, which was supposed to be used for a blood test.

Liu Fei didn't need a knife, and directly separated a drop of blood from the surface of his body in a glass dish and placed it under a microscope for observation.

After looking at it for a long time, he found that his blood was composed of a lot of diamond-shaped cells, like a beehive, connected one by one.

Liu Fei knows a little bit, that is, the morphology of human cells is incomplete, some are fragments, and there are half-moon-shaped oval cells and so on, but his cells are diamond-shaped, and they are very closely arranged.

But other than that, Liu Fei didn't find anything. The best way to know more is to get other people's blood.

Fortunately, it's not difficult here, there are many gangsters in Anqing City, just find a random one to beat out a nosebleed. Liu Fei is not a reasonable person, and the gangster on the other side who dyed yellow hair and looked very hung had not yet reacted, and was smashed by Liu Fei with a punch and broke the bridge of his nose.

"You TM ......"

I don't know what he was scolding, he covered his nose with one hand and pointed at Liu Fei with the other. However, Liu Fei was more concerned about the blood of the gangsters, who knew that the nose of the gangsters was quite firm, and there was no nosebleed this time. No, do it again!

Boom!

The yellow-haired gangster walked away without reacting, and the dark-looking uncle in front of him pulled his hand away and smashed it down with another punch mercilessly.

This...... It hasn't even flowed out yet, it's not scientific!

Liu Fei punched him again.

After four or five punches, the gangster finally bled out, and it was the kind that couldn't stop.

Liu Fei filled some in a test tube, felt that it was okay, and left. Leaving only the thugs who collapsed on the ground, 10,000 grass and mud horses galloped past.

Gangster: Isn't it just a few drops of blood, as for it? Give me a knife, I'll cut it to you, uncle! Do you need to make such a big move?

Liu Fei: If you didn't say it earlier, it would have taken me effort and time.

Gangster: ......

Getting back to the point, after Liu Fei looked at the blood of the gangsters, he made another discovery. There are also many diamond-shaped cells in the mixed blood, accounting for a considerable proportion of the total number of cells, but compared to Liu Fei's cells, the individual is several times larger, and it is not so uniform, many of them are crooked. There are also different forms such as quadrilateral, pentagonal, hexagonal, etc.
