Several students were frightened.

This is the periphery of the battlefield, so there are not many high-level barbarians.

The level 3 barbarian was probably just pa.s.sing by.

But once other high-level barbarians come, they will be dangerous!

“then what should I do? !”

Zhong Yihan was also thinking. At this time, the second rescue team returned to the roof with more than a dozen survivors. There were a teaching a.s.sistant teacher and Shentu Xuan in the team.

Zhong Yihan hurriedly said, “teacher, I may attract high-level barbarian here. help me block a wave of attacks, and I'll set up a formation!”

The teacher was shocked: “formation? What happened? ”

“It's too late to explain,” Zhong Yihan hurriedly said, “Shentu, you can help me hold it for a while!”

Shentu Xuan believed in Zhong Yihan 100% and immediately shouted, “ok!”

Zhong Yihan jumped off the bus and began to layout formation.

At present, there is no formation plate for him to carve patterns, and there is no ready-made altar to use.

So he can only pour the spirit into the Tang knife and then use the Tang knife to engrave the matrix pattern on the cement floor on the roof.

This is a matter that consumes one's spirit and must be very focused. The teaching a.s.sistant teacher immediately sent two people to guard Zhong Yihan to protect him from the barbarian's influence.

It was not long before Zhong Yihan published 12 formation papers. Of course, Shuimu students did not question his formation level.

They had never seen such a thing before, so they had a big question mark in their hearts.

This time, Zhong Yihan is going to arrange a level 2 fog formation.

There is only one core material required by the formation, but it is a bit troublesome to arrange, but it can be done in more than ten minutes at most.

As long as the low-level barbarians lose vision, he can concentrate on dealing with level 3 barbarians, and the fighting will be much easier!

Shentu Xuan held a s.h.i.+eld at the front and shot down several flying barbarians, demonstrating strong battlefield control.

The teaching a.s.sistant teacher also joined in and stood by the side of the building to meet barbarian.

With the two men, Zhong Yihan's pressure suddenly eased a lot. He set his mind at ease and drew lines on the ground.

However, just half of the pattern was depicted, suddenly two loud voices sounded not far away, such as half of the eagle's crow.

The crowd was frightened and looked inside. two barbarians with huge wings like goshawk were flying towards here at a rapid speed. Judging from the pressure they brought and their size of over two meters, it must be two level 3 barbarians!

“All archers, step back three steps and don't come near the edge,” shouted teacher, shocked. “Shentu Xuan, you and I are at the forefront. Others, give Zhong Yihan time! ”

The teaching a.s.sistant is also the strength of big Kung Fu fighter and can stay in Top Four. among big Kung Fu fighter, he is also an elite.

His momentum broke out with all his might, and in an instant, he shocked the two level 3 barbarians.

However, unfortunately, the teaching a.s.sistant teacher is only good at close combat and can't attack from afar, so he can only stand on the edge of the high platform to deter and can't catch up with the two level 3 barbarians.

Shentu Xuan's pressure is also great. This is the first time that he has personally faced two level 3 barbarians.

Although the two level 3 barbarians were careful not to rush up directly, the momentum alone had already forced him out of breath.

Zhong Yihan focused on depicting the formation lines as if everything around him had nothing to do with him.

Ten minutes later, he finally carved the pattern.

At the same time when the last point of the array was engraved, he took out a fist-sized stone from the s.p.a.ce ring and activated it in the formation eye.

For an instant, a gray fog immediately enveloped the entire roof, especially the fog within the scope of formation, with a view of at most one meter.

“yes!”

Originally, low-level barbarians started flying around like a headless fly as soon as they entered the fog. a level 3 barbarian in the sky, was about to fan the fog away with wings. However, it was just about to approach when a kinetic energy arrow suddenly emerged from the fog, almost killing it.

This made the two level 3 barbarians dare not make any move at all, only flying around anxiously in the sky.

Zhong Yihan has five formation cards in his hand, leaving one for himself and distributing the other to other archers. With the formation cards in hand, the fog has no effect.

The crowd has put the second group of survivors on the bus, and the rest of them have gathered together.

The crowd praised the formation one after another. With the fog, even the level 3 barbarian would not dare to break in at will.

The teaching a.s.sistant teacher also laughed: “it's really Zhong twelve. with this formation, we can relax for the time being.”

“Zhong twelve?”

The a.s.sistant teacher laughed: “You shocked the whole formation world by publis.h.i.+ng 12 papers of the formation. of course, you are Zhong twelve.”

Zhong Yihan wry smile, when did he get such a nickname?

But now is not the time to joke, Zhong Yihan said: “Since the formation array has been successfully deployed, it is enough for us to keep watch here. teacher, Shentu, you still need to find survivors as soon as possible and try to save more people before the fog formation fails.”

“Fog formation will fail? How long will it last? ”

“Up to six hours, once this time is exceeded, we can only take the survivors who have been saved away.”

The fog formation upgraded to level 2 after being improved by Zhong Yihan is a consumptive formation. Although the core of the formation is only 100,000, one can only last for two hours at most. Zhong Yihan has only three pieces of stones, which means sticking to it for six hours at most.

“Six hours is enough, Yihan, you must be careful.”

“Don't worry, I will.”

Zhong Yihan took out another 100-pound bow and arrow and looked back at low-level barbarians that crashed west into the fog formation. In his eyes, these barbarians were waiting for him to harvest.

However, after being shot two arrows by Zhong Yihan, the two level 3 barbarians in the sky became more cautious and timid and did not dare to approach easily.

The other four archers, who had won the formation cards, became arrogant at the moment.

As members of the Top Four archery Department, their shooting skills are naturally excellent. Compared with Zhong Yihan's shooting skills, they only have a gap in strength and experience.

However, their close combat strength gap is big, so before there was no cover on the roof, they must allocate more than half of their energy to prevent barbarian's attacks.

Now that they are protected by the fog formation, they are much more relaxed immediately. All they need to do is hide in the fog and shoot low-level barbarians.

In this way, efficiency is greatly improved.

some low-level barbarians were killed, and their dying cries attracted more barbarians.

As a result, the pressure on the shooters in several other buildings in the area was immediately reduced.
