Shouchun City.

Today's Shouchun City is no longer as easy as the original cataclysm, as the former important town of Chu State, but also the city of hope during the cataclysm, Shouchun City at this time has become the center of gravity of the giant siege.

The stone walls and fortresses outside the city, which had been built with a lot of manpower and material resources, have long since been destroyed to pieces.

At first, Fan Li would organize people to repair it, but later, as the number of giants increased and the frequency of appearances became more and more frequent, Fan Li simply did not repair these outer city walls.

Anyway, it will be destroyed if it is repaired, so it is better to concentrate on maintaining the inner city walls.

For more than half a month, three or four different kinds of giants appeared outside the city every day, as if they had grown out of the ground, and they didn't know where they came from, nor why they were so obsessed with Shouchun.

From the head of a sheep to the head of a cow, from the head of a dog to the head of a rabbit, from the head of an eagle to the head of a crane, in short, the head on the neck has its own merits, but the body is still the same body, it has never changed, occasionally changing the equipment on the body, holding an axe, holding a mace or something, full of primitive and bloody atmosphere.

As for ability...... I don't know.

Because every time, without exception, it will be directly cut down by Zhao Zhen, who is almost a "Heavenly Sword".

Zhao Zhen's sword is very fast, so fast that it is impossible for the naked eye to catch it, and it is so fast that it is almost "heavenly punishment".

With each swing, there will be a large number of electric sparks because the air is slashed, and after each slash, the spectators standing on the city wall will always see the giant split in two by a spark, and then hear a roar like thunder.

Like thunder!

"How many are these?" asked Sun Wu, standing at the top of 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." ”

"It's been half a month since this group of giants were trapped here......" Sun Wu loosened his bones, and the whole person showed a tired expression.

"yes, and...... Although Xiao Zhen'er's strength is enough to protect Shouchun, it is not a problem for so many bones to remain outside the city. Fan Li said, looking at the skeletons in front of him and frowning, and sighed long.

When a giant is slain with a sword, the flesh and blood on his body will melt away like spring snow, but his bones will be left behind.

It's like using a skeleton as a scaffold and sticking snow to the skeleton.

If there were only two of these bones, Xue Zhu would definitely be excited, and he would have to make some new blades anyway. But with so many bones left outside the city right now, Xue Zhu wouldn't have time to make weapons even if he had eight arms.

Not to mention that he's missing four fingers.

There is no way to leave the bones outside the city, so they can only organize the soldiers and civilians to think of bringing them in first, and Xue Zhu will classify them first: the best bones will be made into good weapons, and the medium ones will be simply processed into soldiers' weapons.

The most inferior is also harder than ordinary stone bones, so it was turned into a material for strengthening the city wall by Fan Li and pressed on the city wall one by one.

Even so, many of the fifty-one skeletons were still outside the city, and the places that could be put in the city had already been piled up, and there was no place to put them again.

"Giants or something is just a trivial matter, with the thunder bomb invented by me and Xue Candle, it is enough to kill it. Chang Sangjun walked over, groped for the big bone in front of the wall and said, "When my apprentice went to the mountains to pick herbs, he found some strange creatures and some strange plants. ”

"Have you caught any strange creatures?" asked Sun Wu.

"No, because his appearance is too hideous and terrifying, my apprentice does not dare to provoke the other party. Changsangjun shrugged helplessly, and then took out a small flower from his pocket, "Although they are relatively timid, they are not too stupid, at least they brought a little something back." ”

"What is this?" Sun Wu asked, frowning, looking at the flower in Changsangjun's hand.

The flower is not large, small, with pink petals, but if you look closely, you will see that the stamens of this small flower are different from ordinary stamens, or rather, it does not have stamens at all.

"Can I do it?" Fan Li looked at Chang Sangjun.

With the other party nodding in approval, he stretched out his hand and plucked all the petals of the flower one by one, and this strange plant finally revealed its true face.

It was a small, small green snake-like creature, and the tail-like stem at the back had been cut off and plucked off, so it looked wilted, and the little green snake twitched from time to time, looking like a zombie.

"It seems to be a mutation. Chang Sangjun said, "Originally, the position of the stamens became the head of a snake, which seems to be to prey on some small insects or something." ”

"Is it really a refinement? knowing that you prey on something to eat?" Sun Wu raised his eyebrows and couldn't help but say.

"In fact, there are more than these plants that are 'becoming essences', there are also some other bits and pieces, small animals, beasts and so on, all of which have undergone some kind of mutation. Chang Sangjun said,

"Unlike what we've seen in the North Sea before, this mutation is not chaotic, irregular, and disorderly. The creatures we see now, every staggering change in them, has a reason. ”

In other words...... This kind of mutation is actually the 'evolution' of these creatures' chosen by themselves, and not the result of being forcibly reversed by something, right?" Sun Wu guessed.

Chang Sangjun nodded: "It should be." What I saw in the North Sea before was like the worst 'failure' of the Creator, and now this one, although it is a little strange, is at least the one it has naturally selected to succeed. ”

The soldiers guarding the city on the side heard the conversation of several bigwigs, what "mutation", "distortion", "evolution", and a bunch of unintelligible words, which made their heads big.

I only know that guarding Shouchun now, these most ordinary soldiers are actually just decorations, and to be honest, they really have no special role.

When facing the living corpse, the most is to use the crossbow to strafe, and now the living corpse has been cleaned up almost extinct with several major cleanups, and the main enemy is only this terrifying tall giant, and these giants, no matter how powerful the cold weapon, are just tickling the giants.

Just do your own thing.

After all, he is not useless, at least he can keep watch for everyone, remind the attacking giants in time, and reduce the losses of Shouchun City.

The soldier thought silently, encouraged himself, and then opened his eyes wide and looked out of the city walls, unwilling to let go of a clue.

"Huh?" the soldier was stunned for a moment, and in a trance, he seemed to see his own shadow.

Mirror?

He couldn't help but reach out and touch the city wall in front of him, the place where the air was, and muttered, "This is...... What?"

"Oops! Mr. Sun Wu! We seem to be surrounded!" shouted the soldier who immediately noticed the oddity.

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

"Mr. Fan Li! ”

"Your Excellency Changsang-kun, there is also an invisible wall here!"

An anxious voice sounded on the city wall, and Chang Sangjun and Sun Wu immediately threw down the mutated flowers to check the abnormality of the city wall.

They stretched out their hands and touched the original empty place on the city wall, which was now a transparent, invisible, but real, solid wall!

"Open the door!" Fan Li immediately shouted.

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

"Isn't it?, trapped?" Fan Li raised his eyebrows, looked at the "transparent wall" in front of him, and glanced at Sun Wu, and then there was a "bang" knocking sound on the city wall.

Sun Wu's halberd slammed into the "transparent wall" again and again, but it didn't do much damage - at least it seemed like it.

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

"What's the matter? You're blind, you can't do anything without seeing me. Sun Wu attacked several times without results, and said angrily.

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

"What process? The process is that I was made very angry by this thing!

Sun Wu threw away the halberd, rolled up his sleeves, and revealed his strong muscles: "This thing is very evil, obviously you can't see it, but you just can't break it." ”

"Then what does your halberd feel like when it hits this 'transparent wall'?" asked Fan Li.

"Hmm...... It doesn't feel like it's porcelain......" Sun Wu narrowed his eyes, picked up the halberd again, and waved it.

"Bang bang bang!"

A few more swings, hitting the "transparent wall" with a deafening sound.

"How's that?" Fan Li asked.

"Yes, it's just not that porcelain. Sun Wu nodded and said, "I can feel that this wall is not a stone wall, but something similar to a wooden wall or a rammed earth wall. And each time you hit the wall, the hitting points are different, some are deeper, some are not so deep, the difference is within an inch!"

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

"It's not alive, it's supposed to be some kind of peculiar magnetic field. Chang Sangjun got up, held a drill bit in his hand that looked very penetrating and said, "I tried to break the surface with a point, it is indeed some kind of magnetic field, only a magnetic field can form such a resilient barrier." ”

"Magnetic field?" Sun Wu frowned, wanting to think about it, but couldn't help but sigh, "You have some new terms coming up again." Is it new knowledge?"

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

As soon as Chang Sangjun finished speaking, Sun Wu and Fan Li glanced at each other, and instantly knew the new knowledge that Chang Sangjun said, as well as some other incidental knowledge.

"I see, this invisible and untouchable force is the force of the magnetic field, right?" Fan Li said as he touched the "transparent wall" in front of him.

"To put it simply, that's pretty much it. Chang Sangjun nodded.

"All things in the world have yin and yang, and they are mutually reinforcing. Sun Wu got up and threw his halberd at the "transparent wall".

"Zheng ——!"

The halberd plunged into the "transparent wall" fiercely, as if it was floating in mid-air, and the halberd just hung in mid-air, neither falling nor moving.

"In other words, we just need to find an opposite magnetic field and cancel it out?" Sun Wu looked at his halberd that he couldn't get back, turned his head, looked at Chang Sangjun and asked.

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

"It's not. Fan Li suddenly said, "Shouldn't the key to the problem be to find out who made this magnetic field wall? And Zhao Zhen hasn't come in yet!"

"Well, Xiao Zhen'er should be much safer than us when she's outside. Sun Wu looked at his halberd hanging in the air and said, "If this kind of magnetic field wall is artificially made, then you don't have to think about it to know that the other party must be trying to catch us in the urn, right?"

"Ahem, ahem...... That's true, but it's very unpleasant to think about it as a turtle. The corners of Chang Sangjun's eyes twitched in protest.

"Bang!"

The city wall suddenly seemed to be hit hard by something, and there was a violent trembling, which made the people on the city wall a little unstable.

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

"Bang!"

A sword light with electric sparks slashed at the city wall with great condensation, making a dull sound, and then the entire section of the city wall trembled violently.

"Bang!"

Another sword light slashed at the city wall.

"Bang!"

"Bang!"

"Bang!"

One by one, one by one, countless sword lights fell on the city wall.

Every time he was about to touch the city wall, there was always an invisible force that separated the sword light and blocked it, so that the sword light could not really touch the entity of the city wall.

"Bang!"

"Click!"

"Roaring ——!"

Zhao Zhen swung out another sword light, this time it seemed that the force of the sword swing was too violent, so that a crack appeared on the surface of the city wall because of Zhao Zhen's too strong force.

The soldiers on the city wall instantly cheered.

As long as there is a crack, then it means that after a few more clicks, they can be rescued from this strange "transparent wall".

But to the surprise of countless people, Zhao Zhen actually put away the long sword in his hand and turned around and left Shouchun City after carefully examining the crack for a while.

"Hmm......" Sun Wu looked at Fan Li and asked puzzledly, "What do you think this means?"

"I think I received the knowledge of the magnetic field and knew that I couldn't break the magnetic field wall with brute force, so I gave up. Fan Li thought about it for a while, and then understood the reason for the matter.

"Where is Xiao Zhen'er going?" At this time, Xue Zhu walked up to the city wall with a bunch of weapons on his shoulders and asked.

Fan Li, Sun Wu and Chang Sangjun glanced at each other, and said a name in unison:

"Ouyang!"
