"What a sound!" The soldiers standing on the city wall were all in a panic, and with a loud bang, the city wall under their feet shook.

"What's going on, listen to how the sound is coming from inside the city walls. Some of the soldiers poked their heads out and looked but found nothing.

But the sound kept coming.

"What's going on!" Zhou Shu stood at the west city gate, he also heard a noise in the distance, and then saw the soldiers on the city wall become riotous.

"Your Excellency, the walls are shaking, as if someone is striking them. A soldier said.

Zhou Shu was stunned for a moment, then thought of Wu Xiu, and secretly said that it was not good.

Sure enough, soon there were soldiers shouting.

"The walls have been breached, and someone has run out!"

Zhou Shu hurriedly opened the city gate and rushed outside the city, and with a sweep of his eyes, he saw that in the distance, a big hole had been broken in the city wall, and at the same time, a figure was constantly hitting the protective shield, causing the protective shield to vibrate continuously.

"Wu Xiu!" Zhou Shu didn't need to know that that figure must be Wu Xiu who had escaped.

Immediately no longer hesitated, and with the force under his feet, he rushed towards the figure.

Although he was confident in the defensive power of the shield, it didn't mean that he just let Wu Xiu smash it.

"I found Wu Xiu, he was hitting the shield me, I'll go over to stop it first. While running, Zhou Shu used the bracelet to contact Fang Bai and the others.

"You be careful of Wu Xiu's body, he seems to have mutated!" Fang Bai's voice came, making Zhou Shu stunned.

It wasn't until he got close and saw Wu Xiu clearly that he understood what Fang Bai meant by the body mutation.

Isn't that thick right arm mutated, swinging and smashing again and again, some cracks have appeared on the surface of the protective shield, which shows how powerful this arm is.

"If you don't want to die, stop me!" Zhou Shu took out his battle knife and slashed directly at Wu Xiu's head.

"Huh...... Heh......" Wu Xiu let out a heavy breathing sound, his bloodshot eyes glared at Zhou Shu, and he raised his right arm to parry the battle knife that Zhou Shu had chopped.

With a crisp sound, Zhou Shu only felt his knife slash against the incomparably hard metal.

Not to mention cutting off Wu Xiu's arm, even the blue and purple skin couldn't be cut a bit, which shows how strong the defense of this arm is.

With a flick of his arm, Zhou Shu was thrown away directly.

Zhou Shu was also a fourth-order evolutionary, needless to say how natural the power of his one slash was, but Wu Xiu was able to withstand one of his slashes unharmed with just this strange arm.

This is simply not possible for the body of a fourth-order evolutionary to be able to do.

Wu Xiu glanced at Zhou Shu coldly, and then smashed his fist on the protective shield again, obviously he also knew that his first task now was to break through this protective shield and then escape from here.

"Dare to ignore me!" Zhou Shu was annoyed in his heart, and the war knife in his hand began to fluoresce, and he took a step forward and slashed again.

Wu Xiu had no choice but to turn around and stretch out his right hand again, this time he directly grabbed the blade cut by Zhou Shu, although he took two steps back because of the impact attached to the blade, but the palm was still unharmed.

"What!" The shaking in his heart could not be concealed on the face of the tree next week, he had mobilized his own energy to attach to the knife, but he still couldn't break through the defense of this arm.

The energy fluctuations emitted by Wu Xiu, he was sure that it was only at the level of the fourth order, but why could this arm withstand the full force of his own energy.

"A member of Group Z!" Wu Xiu's face was awe-inspiring, and with the force of his palm, he directly twisted the knife into a twist, and then punched Zhou Shu.

Zhou Shu's heart was beating wildly, and he retreated suddenly, but he was still hit in the chest by Wu Xiu's fist style.

As if being hit by a high-speed train, Zhou Shu's body flew out one or twenty meters away and fell to the ground, his brows furrowed, and he looked very painful.

Wu Xiu didn't care about Zhou Shu's life and death, he turned around and hit the protective shield one after another, he wanted to escape before Fang Bai and the others arrived.

This arm seems to be strong, but he can't last long, and it has great side effects on his body, so he must break this shield as soon as possible.

Without Zhou Shu's obstruction, Wu Xiu's fist smashing speed continued to increase, and the cracks on the surface of the protective shield continued to deepen.

Finally, at a certain moment, the protective shield was completely shattered, and Wu Xiu turned around and showed a smile towards Zhou Shu, which looked particularly strange under his blue and purple face.

"I'll be back!"

......

When Fang Bai and the others arrived, they could only see Zhou Shu lying on the ground struggling to get up, but there was no trace of Wu Xiu.

"What about the others?" Guan Ping asked as he picked up Zhou Shu.

"Run, I couldn't keep him, that arm ......" Zhou Shu briefly said about Wu Xiu's changes, as well as that weird arm.

"How long has it been, and where did you run from?" Fang Bai asked.

"About three minutes, in that direction. Zhou Shu raised his hand and pointed in a direction to the west and said.

"Guan Ping, you stay here and watch Zhou Shu, and the others follow me to pursue. Fang Bai said in a deep voice.

Three minutes is enough time for a fourth-order evolutionary to run several kilometers away, and it will be difficult to catch up if you continue to pursue, but you always have to try.

Looking at the shattered protective shield above his head, Yang Shi knew that maybe Wu Xiu had really managed to escape.

"Is a fourth-order evolutionary really that strong?" Yang Shi said darkly.

What he didn't know was that he was able to break the protective shield in such a short period of time, not by relying on Wu Xiu's fourth-order strength, but by his strange arm.

"Forget it, even if Wu Xiu escapes, it is Fang Bai's business to pursue him, and finally there is a clue, I believe they will not give up so well. Yang Shi shook his head, he seemed much calmer, and returned to the room to continue sleeping.

Next, without Wu Xiu's Open Source City, the major forces will inevitably begin to stir.

Even the gathering place of Open Source City is likely to be completely out of the control of the state and officially taken over by a certain force in the city.

However, this has nothing to do with him, if you have to hope that any force will occupy the position of city lord, it is naturally the Bass family where Hayes is located.

After all, he had a close relationship with Hayes, and it would have helped him a little if they had become the official rulers of the Gathering.

The next day, Yang Shi learned from Fang Bai that Wu Xiu had indeed escaped, and their follow-up pursuit had failed to catch him.

The main reason is that Tianfeng happened not to be in the open source city yesterday, which allowed Wu Xiu to successfully escape, otherwise with Tianfeng's strength, Wu Xiu would not have a chance to escape.

Later, they also said that they would take Li Hu back to Longhu City, the headquarters, and as for Wu Xiu's whereabouts, they would continue to be tracked down by other Group Z teams.

As for the vacant position of the city lord in Open Source City, their attitude was indifferent, as if it was just a trivial matter, and they didn't bother to care about it at all.
