I only have passive skills, so I'm extremely cautious

The term "survival mode" was given by later generations, and it was a rule that was summarized after more than a dozen large-scale deaths.

The two days of closure were actually the automatic repair of the maze formation, and of course, it also became the killing day for monsters!

The monsters seemed to have agreed to launch a magic tide and ravage the maze. Some killed people, and if no one was there, they killed each other, venting the violent emotions brought by magic.

Generally speaking, before the survival mode is turned on, self-aware adventurers will hurry out, and those who stay behind are either rookies or real strong men.

"There must be something wrong when things are abnormal. Today's incident may be the beginning of some major disasters!" Bai Qi kept slapping out palm winds mixed with ice chips.

The ice chips were like steel balls, piercing the heads of monsters one by one.

"It is necessary to hold a summit meeting after returning and report to the hall master and others!" Lang Yue replied seriously, "A comprehensive inspection of the formations of the five major mazes and the movements of the magic cave!"

Uh...

Chen Zhong, who was standing behind Lang Yue, rubbed his face and wanted to tell them that there was no need.

Coincidence!

Everything is a coincidence!

Gradually, the small demon tide stagnated, and no more demons poured out of the passage.

"Please pile up the corpses of the demons at the entrance of the cave, leaving only three so that someone can escape."

"I hope everyone can take out some spiritual stones. I need to set up a spiritual array to defend against a stronger demon tide!"

"Everyone check the remaining supplies and make reasonable arrangements on your own to ensure that there are enough trump cards to deal with the collapse of the defense line!"

Lang Yue has considered the worst case scenario, and he started to arrange it after giving the order.

The first people who took out spiritual stones for him were the members of Tianyan Academy and Tianyan Hall, then the major sects, and finally those shy and independent adventurers.

Lang Yue did not blame them, he could understand their thoughts, and besides, they probably couldn't take out much resources.

It's okay to show some expression, as long as it's not for free!

Chen Zhong took out ten spiritual stones. As a freshman, this is already a lot, but compared with his reserves, it's a drop in the bucket.

Everyone took action, life and death depended on everyone.

"Don't rush to take out the magic cores, the first thing now is to build a defense line! Otherwise, everyone will have no blessing in this life!" Bai Qi shouted in a deep voice, and he found that many adventurers were smashing the heads of monsters.

This was too time-consuming!

If the attitude was not firm, these old-timers would not take it seriously at all!

Hearing the impatience in his tone, a bunch of people became much more honest.

Chen Zhongcai was not so honest.

While piling up the monster's bones high to block the cave entrance, he quietly took out the magic cores. In such a short time, he had already harvested fourteen first-level magic cores and one second-level magic core!

The cave entrance was very high and large, and the corpses were exhausted, only half of each cave entrance was covered.

But it was enough.

Lang Yue began to set up the formation, turning the monster's bones into part of the formation, becoming indestructible, and a natural cornerstone obstacle.

Fifth-grade defense formation!

Fourth-grade reinforcement formation!

Fourth-grade light formation!

Time was in a hurry. Just as he was about to set up the fourth spiritual formation, a huge and noisy sound of footsteps turned into a sound wave and came from all directions.

Lang Yue's expression changed unnaturally. His powerful soul had already swept over and roughly saw the demon tide that was ten times more terrifying than before pouring out from the first and second floors of the stairs!

They smelled the breath of humans, were attracted by food, and awakened the desire of their taste buds.

"Rise!" Lang Yue pinched his hand seal, and three spiritual formations rose.

In an instant, the monster corpse barrier was hit hard, but with the blessing of the spiritual formation, it resisted. The monsters behind roared unwillingly and then had to withdraw.

Gu...

Chen Zhong swallowed a mouthful of saliva. This did not mean that the monsters retreated. They would run out from the three wide-open exits in a while.

Lang Yue's consideration was very thorough. He did not block all the holes. Doing so would only cause him to lose sight of the overall situation and disperse the energy of the spiritual formation.

The three holes are only so wide, and there are only so many monsters coming out at once. The thousands of them can completely sustain consumption, kill one if one comes out, kill ten if ten come out!

When the dozen charging monsters rushed into the hall, the light array in the hall immediately started, and the beams containing a large amount of light spiritual power burned through their bodies, and also slowed down the speed of the monsters behind.

"This is not appropriate." Chen Zhong frowned. They are actually passively defending now, and they are easily defeated when supplies are insufficient.

Moreover, who dares to guarantee that the door will be opened in two days?

What if this is not the so-called survival mode at this moment?

"Dean, I have contacted the college. All forces are now gathering outside the maze hall and are trying to find a solution." Wu Feifei put down the phone with poor signal and reported to Lang Yue who was controlling the spirit array.

There is a signal tower in the maze, and the maze is the middle point between the lower world and the other world, not a completely other world, so a very poor signal can be received.

"Okay, since they are already thinking of a solution, we just need to hold on." Lang Yue said, but his twinkling eyes were full of worry.

The second wave of demons was just that strong.

Are there really no fourth-level or even fifth-level monsters?

Under normal circumstances, monsters of that level would not bother to climb up the first few levels, but that was the normal situation...

The battle continued, and most of the ammunition was consumed.

The corpses in front of the three caves were piled up like a mountain, and many close-combat adventurers had been torn apart and turned into food.

"Damn it!" Wang Taiping yelled, "Why are we so unlucky? This is the first time we come to this maze and this kind of unlucky thing happened!"

"Who says it isn't?" Tang Sui smiled bitterly.

These new students, in the past, close combat was a dead end, and they could only contribute a little bit with some long-range weapons.

In other words, Lang Yue and the others were completely protecting them!

Otherwise, they don't need to defend at all. They would go directly deep into the maze, engage in guerrilla warfare or hide, which would be better choices!

"We...are a burden!"

As the fighting became more brutal, many students began to choke.

Whether it is a monster or a human, this moment can be described in one sentence - life is like grass.

"Die to me——"

Suddenly, a hearty roar sounded from the entrance of the cave.

I saw a man wearing the uniform of a Tianyan Academy instructor rushing towards a huge creature.

The man was already covered in scars and was dying, but he still rushed over and pulled the tab, revealing a dozen spirit stone fragment grenades hanging on his body.

boom--

Fire exploded.

The mentor and the monster blocking the entrance of the cave were shattered into pieces.

"Old class!!!" His students all screamed with tears in their eyes.

That was the head teacher of the third class of the freshman class.

With the blockage of that huge monster, another channel is free from the monster's intrusion.

The other two cave entrances gradually calmed down, and the second wave of magic stopped.

The ground is in shambles, and the ground is in pieces.

Everyone was silent.

Chen Zhong also fell silent, with mixed feelings in his heart.

Maybe this raging demonic tide will happen sooner or later, but the function of the magical skills of the rules makes it happen now.

Lang Yue didn't say anything, nor did he take the opportunity to educate the students like in the TV series.

Preparing for the third wave is more important than giving a tearful speech.

Half an hour later, everyone was still resting.

Lang Yue, who was repairing the spiritual formation, suddenly stood up and roared, "Alert!"

In full view of everyone, a large and long afterimage quickly jumped out of the hole.

It knocked down the white chess piece that was cleaning up the mess, and bit it down with its big mouth. The body of the white chess piece on the ninth level of Xiaocheng Realm was separated, but it didn't react at all.

The monster chewed its mouth that occupied the entire cheek, and white liquid flowed out from between its teeth.

It has a snake-like soft body with countless spider legs on both sides. Its head is a smooth ball with no eyes or nose, and only a big mouth that can tear the head into four pieces.

"The fourth level peak monster! The gluttonous giant ghost!"

Chen Zhong was so frightened that he no longer cared about the consumption of spiritual power, and directly activated the Divine Movement Escape and Xuanwu Body tenfold.

The fifth-grade spiritual engraving pen is held in the right hand, and ten third-grade spiritual talismans are held in the left hand.

The situation has worsened, prepare to run away!
