If it had been before, he wouldn't even face more than a dozen rats head-on. The reason is very simple, two fists are hard to beat four hands. If it's a few, maybe it's nothing, but if it's a dozen, maybe you'll get hurt.

But now, it seems to be easy and enjoyable.

Stopping his body, Liu Fei didn't go to Li Hai's side, but instead used the giant rat to train the qi in his body. How can you kill a giant rat at the least cost; how to make glaucoma a weapon; Precise control of the movement of qi in the body, many things.

Liu Fei even found that Qingguang could condense a green sword or green knife in his hand, and with the three-foot Qingfeng in his hand, he didn't feel the slightest strength at all, but he was blowing and breaking his hair.

Although Liu Fei really wanted to use this to replace ordinary swords, Qing Feng's consumption was huge, and with the qi in his body now, it could only last for more than an hour.

It's enough to deal with a fight, but don't forget, qi is equal to his physical strength. If he runs out of gas, he will fall into exhaustion, and then he will be slaughtered.

Generally speaking, he will only enter weakness when he has only ten percent of his qi left. So he deliberately set aside 15 percent and set it aside, while the rest of the qi was invoked at will.

Liu Fei was exercising himself, but Lehi on the stone wall was suffering. The city's ammunition has basically been depleted, and many backup means have been used, but the rat tide has not subsided.

"Nai's, why are there so many rats this time?" Li Hai scolded. With a single punch, he knocked out a giant rat that had climbed up the wall.

But more giant rats rushed up, like waves of red slapping on the other side.

Rats can bend their fingers as nimble as humans do, and they are able to climb near-vertical rock walls, which are no problem.

The rats were like a tide, and in an instant, they flooded the high wall, and countless giant rats piled up. The soldiers on the stone wall are like boats, ready to capsize at any moment.

The soldiers all took out their weapons and swung them at the giant rat. These scarlet rats are only slightly larger than normal rats, but their claws are so sharp that a single bite can take away a piece of meat from a soldier.

Lehi couldn't help it, and he stimulated the qi in his body, and his whole body was white. There are white edges on the fists and feet, and the edges are only a few inches long, but when it comes to harvesting giant rats, it is extremely not weak.

A giant rat a few points bigger than a house cat bit him, he didn't look at it, and with a punch, the giant rat flew dozens of meters away and smashed into the rat tide.

The number of giant rats is terrifying, and even some ordinary people can kill them. This punch Lehi didn't even use his breath, and he used pure strength.

After understanding the 'weakness' of the mouse, Liu Fei didn't get angry anymore, and when it came to punching and kicking, his strength was not weaker than Li Hai at all.

Collapse fist was used by him, it used to be just a practice of boxing, but now it is a real battle, Liu Fei's understanding of collapse fist has reached a higher level.

Each punch only knocked the giant rat flying. However, when the giant rats fell to the ground, it was discovered that these giant rats were all bleeding. It seemed like a simple punch, but in fact, Liu Fei used the strength of the collapse fist to directly shatter the giant rat's internal organs.

After a few rounds, the little rats were basically killed, and the remaining giant rats were generally the size of domestic cats, and their strength was low-level ordinary. There are also some giant rats that are a few points bigger than the earth dogs, and their strength has reached the low-level elite.

These giant rats are already a threat to the soldiers, and if they are not careful, the soldiers may be pounced on by the giant rats. The rat's minions can easily tear through the flesh of a soldier.

Soon, there were casualties in the army, not a few, but a large part. Because of the long-term training, most of the soldiers' strength is in the second grade. However, the second level has not been separated from the scope of physical combat, 'two fists are hard to beat four hands', and it is inevitable that several giant rats will be injured under the siege.

Liu Fei, who was observing, quickly noticed a hint of abnormality, and his eyes could see qi. There are about twenty or thirty Grade A powerhouses in the army, which is quite a high percentage. However, there is also a white qi far away from the stone wall, if it weren't for Liu Fei's amazing eyesight, I'm afraid he wouldn't be able to see it.

The qi of this organism is relatively simple, with only a dozen branches, unlike the qi in the human body, which is as dense as the roots of a tree.

Liu Fei suddenly became interested, the giant rat was no longer enough for him to use qi, he had to find a high-level fierce beast! Isn't that the goal?

Jumping a few feet away, Liu Fei rushed out hundreds of meters in a blink of an eye, and even regardless of his feet, several giant rats were directly trampled into meat paste by him.

This high-level fierce beast was about two kilometers away from Liu Fei, but in Liu Fei's eyes now, two kilometers was not a distance at all. With the blessing of Qi, his speed could exceed one hundred and fifty meters per second, and before half a minute, he could see the source of Qi.

A bloated giant rat, a 'giant rat' in the truest sense of the word, the size of an elephant.

The giant rat found Liu Fei, and a sharp sound came out of his mouth, which actually made Liu Fei's mind a little swollen.

Liu Fei immediately blocked his ears with air, and the feeling of swelling subsided.

The giant rat screamed, but its body moved. Naturally, he didn't attack Liu Fei, but fled!

Timid as a mouse, timid as a mouse! Even if the rat's guts become a high-level fierce beast, it is too small.

Finally came over, how could Liu Fei let this giant rat go? Don't look at the huge size of this giant rat, but it is not slow, and it must have a speed of 200 yards to run and race a car!

However, Liu Fei was faster, chased after him, and spit out a mouthful of green mang, shooting directly at the giant rat's huge body.

This ability to spit out green mangs is learned by incarnating a giant ape, this thing kills people invisibly, and spits out a mouthful of green mangs, who can guess?

Of course, because it is a mouth spit, naturally there will not be too much, only slightly stronger than the snap of a finger.

This 'mouth belly honey sword' was just about to hit the giant rat, but it was blocked by a white light shining from the giant rat, which was naturally useless.

The giant rat was huge, and the qi content in its body was three or five times more than that of humans, and it ran wildly all the way without stopping, and in a blink of an eye, a large black hole appeared in front of it.

Liu Fei immediately stepped forward and grabbed the giant rat's tail and pulled it hard. The size of this giant rat was not in vain, so Liu Fei pulled the giant rat, but was pulled into the burrow by the giant rat.

In the final analysis, Liu Fei is still too confident in his own strength, even with the help of qi, the gap in size is there. The giant rat weighs at least four or five tons, while Liu Fei is no more than a hundred kilograms at most, a difference of dozens of times.

Liu Fei, who entered the cave, burst out of his hand with a stream of blue light, directly cutting off the rat tail on his hand.

The giant rat didn't care, and ran away!

Liu Fei rolled a few times on the ground because of the buffer, but when he got up, he found himself in a small three-pronged opening, and the direction he came from was long unrecognizable.

This place is underground, although Liu Fei reacted the moment he entered the cave just now, but the speed of the giant rat is also sixty or seventy meters per second. In just a few seconds, Liu Fei was afraid that he would be hundreds of meters deep into the hole.

Even if you use qi to help your eyes, you can only see your surroundings clearly. Liu Fei's eyes also did not have the function of penetrating the wall, so naturally he could not see the open path clearly.

After a while, a squeaky sound sounded all around, and small mice with fists rushed towards Liu Fei. These rats were fleshy, and they looked like they had just been born, but they opened their fangs and sharp mouths, and rushed towards Liu Fei one by one to defend their immortality.

Liu Fei's whole body flashed blue, and the surroundings were emptied. Just now, he put his qi out a few meters and directly killed hundreds of little mice.

However, there were countless little mice surrounding him, and these mice could not harm Liu Fei at all. Only use a small part of the qi to cover the whole body, and let this group of little guys bite it, and it won't break the defense at all!

No matter! It's still important to find an outlet!

There are three intersections, and one seems to be uphill. Liu Fei couldn't tell the difference, so he walked this road directly.

However, the forks are getting more and more, and Liu Fei has encountered as many as eight forks along the way. After walking for nearly an hour, Liu Fei began to get confused, and he couldn't find this way at all!

The rats at his feet were like a tide, and several giant rats the size of wolf dogs rushed out, all of which were killed by Liu Fei. There were not only rats on the ground, but also many skeletons, which were so messy that no one could tell who it was! However, there are some skulls that are particularly noticeable, and that is the human skull.

In the end, Liu Fei simply used the old method, which was to sit on the rock wall in the corridor to sign that he had been there.
