Outside the confinement room, the guards hurried to the control room where Long Xiaotian was, and Long Xiaotian was watching the training of the students in the control room.

"Dragons. The guards rushed in in a panic.

"What's going on?" Long Xiaotian asked, and if he looked closely, it was the guards guarding the confinement room, presumably something was going on in the confinement room.

"That'...... The students had strayed into the nightmare rat's lair. ”

"What? "Long Xiaotian didn't expect Chen Yan and them to actually enter the nest of the Green Nightmare Giant Rat, although the Green Nightmare Giant Rat's evolution has not yet been completed, and its combat effectiveness is not very high, but it has a great advantage in numbers, Long Xiaotian knows that the nest of the Green Nightmare Giant Rat is near the confinement room, but he doesn't know why there are Green Nightmare Giant Rats in the confinement room.

"I don't know what's going on lately, but the blue rat seems to have opened a passage to the confinement chamber, and often appears in the corridors of the confinement chamber. ”

"Then why didn't you report it?"

"I wanted to report it, that is, the day you went out on a mission, I wanted to wait for you to come back and report it, but then I forgot about it. ”

"You...... Is there a way to get them out?" Long Xiaotian knew that the guards couldn't be blamed entirely for this, he also had a certain responsibility.

"The space they're in now, we can't get into, we have to let them come out on their own. ”

"Chen Yan depends on you. Long Xiaotian said silently in his heart, he knew that he would not lock them in if he said anything, but now it was too late to say anything, and he could only pin his hopes on Chen Yan.

Seeing that his subordinates were actually destroyed by Chen Yan's move, the green mare giant rat was immediately furious and began to howl, the cry was extremely harsh, and everyone covered their ears.

After the scream, a rumbling sound was heard from far and near, the same as the sound of the green mare giant rat group running before.

In an instant, Chen Yan and the others were already surrounded by the group of green monster rats.

"Chen Yan, save us. Fang Jin and the others had nothing to do, they had already shrunk into a ball and begged Chen Yan for help.

The space they could stand in was getting smaller and smaller, and Fang Jin was already hanging on his little brother like a koala.

"It's a nuisance. Chen Yan said in his heart, these people are really a burden to him.

The eyes of the green tare giant rat looked directly at Chen Yan and the others, approaching step by step, but they did not attack, as if waiting for some instructions.

Suddenly, the largest of the nightmare rats roared, and the other nightmare rats pounced on them as if they had received an order.

Seeing the situation, Chen Yan took a step back and hit the fireball into the ground, and suddenly pillars of fire poured out from the ground, surrounding Chen Yan and the others, causing the group of green giant rats to be unable to get close, and they also burned a few to death.

"It's hot. Fang Jin and the others stayed inside the barrier formed by the pillar of fire, like a steamer.

Chen Yan couldn't stand it anymore, the temperature here was getting higher and higher, and if it continued like this, it was estimated that this pillar of fire would not last long, even if it wasn't bitten to death by the blue monster rat, it would be roasted in the barrier.

The Blue Nightmare Giant Rat had stopped attacking, as if waiting for Chen Yan and the others to kill themselves in the pillar of fire.

"You make the circle bigger. Liu Yao shouted to Chen Yan that he was already too hot.

Chen Yan was woken up by Liu Yao's words, why should he fence himself, just surround the blue mare giant rat and shrink the circle.

Pillars of fire appeared on the ground again, surrounding the Pillar of Fire, and their barrier of Pillar of Fire continued to expand, while the outer pillars of fire continued to shrink, and the Pillar of Fire had nowhere to escape, and was burned to ashes by the pillar of fire.

"Finally out of danger. Chen Yan put away the pillar of fire and sat on the ground, the attack just now consumed a lot of his physical strength.

But the crisis has not been resolved, the largest green monster giant rat actually burrowed into the ground when the pillar of fire attacked just now, dodging, and now it sees that the pillar of fire has disappeared and jumps out from under the ground.

It looked at the corpses of its own hands on the ground, and now it was the only one left, and it couldn't care so much, and it wanted to break the net with Chen Yan.

"It also has 2,000 ability points?" Chen Yan suddenly felt the ability points of the green monster rat, a mouse actually has ability points, which made Chen Yan a little surprised, he had only heard of people having ability points before, and when he went out, he would ask Long Xiaotian.

"Is that an exit?" Suddenly, Liu Yao saw a hole behind the blue mare giant rat, and some sunlight leaked in from this hole.

"I'll hold him back, and you guys will find a chance to get out of the hole over there. Chen Yan stood up from the ground again, he made the Green Giant Rat suffer heavy losses, and this boss would definitely not let him go.

In the blink of an eye, the Green Nightmare Giant Rat had already rushed over, Chen Yan once again used a fierce flame spray, and the pillar of fire poured out from the ground, but the speed of the Green Nightmare Giant Rat was extremely fast, and the pillar of fire couldn't hit the Green Nightmare Giant Rat at all.

The green mare giant rat collided directly with Chen Yan, and Chen Yan was immediately blown out, and before Chen Yan could land, the second attack of the green mare giant rat was picked up.

Chen Yan threw a fireball at the Green Mouse Giant Rat, and the Green Nightmare Giant Mouse had no way to dodge because it was in the air, and the fireball hit the center of the Green Nightmare Giant Rat's eyebrows.

The green mare giant rat screamed, the position where the fireball just hit was its weakest position, and the fireball just now also had a certain lethality, and the painful green mare giant rat screamed wildly.

At this time, Chen Yan also landed, and without any hesitation, he directly launched an attack on the green monster rat.

Fang Jin and the others took advantage of the fight between Chen Yan and the Green Nightmare Giant Rat, and had slowly come to the entrance of the cave, although there was still some distance from the ground, but the visible sunlight had already made them see hope.

The exit is vertically upward, and one can barely pass through, but it is very difficult to climb up, and it is impossible to use one's hands and feet at all.

"This hole dug by rats is really not accessible to ordinary people. Fang Jin complained, he couldn't climb up this hole, his body was too burly.

Chen Yan and the Green Nightmare Giant Rat were both defeated, and now they didn't dare to attack rashly, but they both stared at each other, as if they were on guard against each other's attacks.

"It's really tough. Chen Yan wiped the blood from the corner of his mouth, he had to think of a way, if he continued to be entangled like this, it would only be more detrimental to them.

The most serious injury of the green mare giant rat now is the eye, Chen Yan several fireballs smashed on the eye of the green mare giant rat, the green mare giant rat can no longer see clearly, can only see Chen Yan's blurred figure.

If Chen Yan launched an attack now, the Blue Nightmare Giant Rat would definitely not be able to dodge, but Chen Yan no longer had the strength to attack.
