Shouchun City.

Today, Shouchun City is no longer as easy as the catastrophe. As a former important city of Chu State, it is also the city of hope during the catastrophe. At this time, Shouchun City has become the center of siege of giants.

The stone walls and fortresses that had been built outside the city had already been destroyed and broken.

At first, Fan Li would organize people to repair it, but later as the number of giants increased and the frequency of appearance became more and more frequent, Fan Li simply stopped repairing these outer walls.

Anyway, it will be destroyed after repairing it, so it is better to concentrate on maintaining the internal city wall.

For more than half a month, three or four different kinds of giants appeared outside the city every day. They seemed to grow out of the ground, neither knowing where they came out nor why they were so persistent in Shouchun.

From sheep's head to cow's head, from dog's head to rabbit's head, from eagle's head to crane's head, in short, the heads on the neck have their own advantages, but the body is still the same body, and it has never changed. Occasionally, I will change my equipment on my body, holding an axe, a mace, or something, full of primitive and bloody breath.

As for the ability... I don't know at all.

Because every time, without exception, Zhao Zhen, who is almost "Sky Sword", will be directly cut off with one sword.

Zhao Zhen's sword was so fast that it could not be captured by the naked eye, so fast that it was almost "divine punishment".

Every time you swing, a large number of electric sparks will appear because of the cut-out of the air. After each slash, people standing on the city walls to watch the battle always see the giant split into two by an electric spark, and then hear the roar like thunder.

Like thunder!

"Which one is this?" Sun Wu asked while standing on the wall, looking at the giant's fallen body.

Fan Li took out a roll of bamboo slips, carved another one on it, and said, "This is the fifty-first one."

"It's been half a month since I was trapped here by these giants..." Sun Wu stretched out his bones and showed a lazy look.

"Yes, and... although Xiao Zhen'er's strength is enough to protect Shouchun, it's not a big deal to stay so many bones outside the city." Fan Li said, frowned at the skeletons in front of him, and sighed a long time.

After the giant was killed by a sword, the flesh and blood on his body would melt away like spring snow, but it would leave his own bones.

It's like using bones as a bracket and then sticking snow to the bones.

If there were only one or two of these bones, Xue Zhu would definitely be very excited and would have to make some new weapons no matter what he said. But now so many bones are left outside the city, even if Xue Zhu had eight arms, she would not have time to make weapons.

Not to mention that he had four fingers missing.

There is no way to keep the bones outside the city, so the military and civilians can only be organized to remember to take them in first, and Xue Zhu first classified them: the best bones will be made into the best weapons, and the medium ones will be simply processed into the soldiers' weapons.

The most senior one is harder than ordinary stone skulls, so Fan Li and others turned it into materials to reinforce the city walls and pressed them one by one on the city walls.

Even so, there were still many of the fifty-one bones left outside the city. The places that could be placed in the city were already full and there was no place to be placed.

"The giants are just small matters. The thunder and fire bombs that Xue Zhu and I invented are enough to kill them." Changsangjun walked over and groped in front of the wall and said, "When my apprentice went to the mountains to pick herbs, they found some strange creatures and some weird plants."

"A strange creature? Have you ever caught it?" Sun Wu asked.

"No, because my apprentice is too hideous and terrifying, my apprentice doesn't dare to provoke the other party." Changsangjun shrugged helplessly, then took out a small flower from his pocket. "Although they are relatively timid, they are not too stupid. At least they brought some things back."

"What is this?" Sun Wu frowned and asked as he looked at the flowers in Changsangjun's hand.

This flower is not big, small, with pink petals, but if you look closely, you will find that the stamens of this small flower are different from ordinary stamens, or it has no stamens at all.

"Can I do it?" Fan Li looked at Changsangjun.

With the other party nodding and permission, he stretched out his hand and took off all the petals of the flower. This strange plant finally revealed its true appearance.

It was a small creature like a green snake. The stem like a tail behind it was cut off and picked off, so it looked wilted. The little green snake twitched from time to time, looking like a zombie.

"It seems to have mutated." Changsangjun said, "The original position of the stamen turned into a snake's head, which seemed to be to prey on some small insects or something."

"You really become a sperm? You know you've preyed on something and eaten?" Sun Wu raised his eyebrows and couldn't help but say.

"In fact, there are not only these plants that are 'shen', but also some other scattered things, small animals, wild animals, etc., and some kind of changes have occurred." Changsang Jun said,

"Unlike what we saw in the North Sea before, this kind of change is not chaotic, irregular, and orderly. Every striking change in the creatures we see now has a reason."

"In other words... this kind of change is actually the result of the 'evolution' chosen by these creatures themselves, rather than being forcibly reversed by something, right?" Sun Wu guessed.

Changsangjun nodded: "It should be. I saw it in Beihai before, like the worst 'failure' of the Creator, but now, although it is a bit strange, at least it is a successful person it naturally selected."

The soldiers guarding the city side heard the conversation between several bigwigs, such as "mutation", "distortion", "evolution", and a bunch of words that they couldn't understand, making them feel overwhelmed.

I only know that the most ordinary soldiers of guarding Shouchun are actually just decorations and really have no special function.

When facing a living zombie, at most, it is to use a crossbow to shoot. Now, the living zombies have been almost extinct with several major cleanings. The only enemy they face is this terrifying tall giant. No matter how powerful these giants have cold weapons, they are just tickling the giants.

Forget it and do your own thing well.

After all, I am not useless. At least I can keep a watch for everyone and promptly remind the attacking giants to reduce the losses in Shouchun City.

The soldier thought silently, encouraged himself, then opened his eyes wide and looked outside the city wall, unwilling to let go of any clues.

"Huh?" The soldier was stunned for a moment. In a trance, he seemed to see his own shadow.

Mirror?

He couldn't help but stretch out his hand to touch the city wall in front of him, and murmured to himself: "What is this?"

"Oh no! Mr. Sun Wu! We seem to be surrounded!" The soldier who immediately noticed something strange shouted.

"Mr. Sun Wu, an invisible wall appeared on the city wall!"

"Mr. Fan Li! So is here."

"Hisser Changsangjun! There is also an invisible wall here!"

An anxious voice sounded on the city wall. Changsangjun and Sun Wu immediately left behind the mutated flowers and checked the abnormalities of the city wall.

They reached out their hands and touched the originally empty place on the city wall. Now it is a transparent, invisible, but real, physical wall!

"Open the door quickly!" Fan Li shouted immediately.

"No, Mr. Fan, the city gate is blocked by something!" The soldier guarding the city gate responded immediately.

"No, is it? Trapped?" Fan Li raised his eyebrows, looked at the "transparent wall" in front of him, and looked at Sun Wu. Then, a "bang bang" sounded on the city wall.

Sun Wu's long halberd collided with the "transparent wall" one after another, but did not cause any damage - at least it seemed.

"Trouble." Fan Li looked at Sun Wu and asked, "How is it?"

"What's wrong? You're blind, I can't do anything if I didn't see it." Sun Wu said angrily without results when he attacked several times.

"I'm not asking the result, I'm asking the process." Fan Li rolled his eyes.

"What process? The process is that I am very angry with such a thing! Humph!"

General Sun Wu threw away the long halberd, rolled up his sleeves, revealing his strong muscles: "This thing is very evil. It is obviously invisible, but it just cannot be broken."

"What does your long halberd feel when it hits this 'transparent wall'?" Fan Li asked.

"Um... it doesn't feel solid..." Sun Wu narrowed his eyes, picked up the long halberd and waved it.

"Bang bang bang!"

A few more waves hit the "transparent wall" and made a deafening sound.

"How is it?" Fan Li asked.

"Yes, it's not that solid." Sun Wu nodded and said, "You can feel that this wall is not a stone wall, but a wooden wall or rammed earth wall. And every time you hit the wall, it's a wall

The hit points on the top are different, some are deeper inwards, some are not that deep, and the difference is within an inch!"

"Is this 'transparent wall' alive?" Fan Li said his assumption.

"It's not alive, it should be some kind of strange magnetic field." Changsangjun stood up, holding a drill bit in his hand that looked very cunning, "I tried to break the surface with a point. It was indeed a kind of magnetic field. Only the magnetic field would form such a tough barrier."

"Magnetic field?" Sun Wu frowned, trying to think about it, but couldn't help but sigh, "You have some new nouns emerging. Is it new knowledge?"

"Don't worry, new knowledge will be in your mind right away."

As soon as Changsangjun finished speaking, Sun Wu and Fan Li looked at each other and instantly learned about the new knowledge Changsangjun said, as well as some other knowledge along with it.

"So that's it. This invisible and intangible force is the force of the magnetic field, right?" Fan Li said, touching the "transparent wall" in front of him.

"Simply put, that's about it." Changsangjun nodded.

"All things in the world have yin and yang, and they are mutually generated and restrained." Sun Wu stood up and threw his long halberd hard on the "transparent wall".

"Zheng--!"

The long halberd pierced into the "transparent wall", as if it was floating in the air. The long halberd hung in the air, neither falling down nor moving at all.

"In other words, we just need to find an opposite magnetic field and offset it?" Sun Wu looked at his long halberd that he could no longer get back, turned around and looked at Changsangjun and asked.

"Uh...yes, that's the theory." Changsangjun spread his hands and showed a helpless expression, "But we don't know what the opposite force of this magnetic field is."

"No." Fan Li suddenly said, "Isn't the key to the problem? Shouldn't it be to find out who made this magnetic field wall? And Zhao Zhen hasn't come in yet!"

"Well, Xiao Zhen'er is much safer than us outside." Sun Wu said to his long halberd hanging in the air, "If this kind of magnetic field wall is made by man, then you don't have to think about it. The other party must want to catch us in the jar, right?"

"Ahem... I'm right, but I feel uncomfortable no matter how I think about it." Changsangjun's eyes twitched and protested.

"Bang!"

The city wall suddenly seemed to be attacked by something heavily, and a violent tremor occurred, which made the people on the city wall feel a little unstable.

"What's the situation?" Fan Li was stunned for a moment, and then saw Zhao Zhen who was preparing for the momentum and then preparing to wave his sword.

"Bang!"

A sword light with electric sparks slashed on the city wall in an extremely conspicuous manner, making a dull sound, and then the entire city wall trembled violently.
