With the injection of the black elixir, the tongue of the student began to expand continuously, becoming thicker and thicker, at least one meter thick and three or four meters long, and the color became dark black, and the tongue fell to the ground with a bang, which was so big that it dragged to the ground!

Such a strange picture, Aya Xiaocheng is the first time to see it, and using the tongue as a weapon is really a very "innovative" idea.

"Puff puff!"

Aya Xiaocheng fired several shots in a row, this was his test method, and when he flicked his tail, the bullet crackled and fell to the ground.

It seems that there is still something about this black thing, at least this defense has reached the level of steel.

However, someone rushed over one step ahead of Aya Xiaocheng, and the stone demon ran and jumped into the air, smashing his arms like Mount Tai pressing the top, and the huge black tongue was thrown violently by the research force, and the two collided, making a loud "boom" sound!

"Yes, yes, yes! That's the battle! This is a showdown between men! ”

The stone demon threw a few punches in a row, and the force was so great that it was like the impact of a small train speeding from a distance, but Sheng Yanyan was not to be outdone, his black tongue was like an iron wall, constantly colliding with his fist, producing bursts of white air shocks!

"It seems that this opponent is really suitable for him."

Aya Xiaocheng saw that they were fighting back and forth, and he didn't bother to go over and intervene, so it was better to mend the knife, and Man Ruyan, who was lying there dying, probably didn't know that someone was "spying on her body".

"Damn narcissist, tell you to wait for me to come along, don't wait for me, you deserve to be killed now."

Sheng Yan said so, but in an instant, he increased the intensity of his throw, knocked the stone demon back, and then ran in front of Man Ruyan, aiming at Aya Xiaocheng is a tongue flat press!

Aya Xiaocheng didn't choose to hit it hard, but took a small step back, and with a "bang", the floor began to crack, and he quickly slashed several times in succession, and several cracks were scratched on his black tongue, which made Shengyan want to cry out in pain.

I couldn't stand it anymore, and a "Thomas whirlwind" on the spot forced Aya Xiaocheng to stop attacking and retreat backwards, but this is like a wheel battle, one ends, and the other is connected, and the stone demon has already raised his arm that turned into a rock giant hammer and smashed it down!

Seeing this scene, Sheng Yanyan once again "cordially greeted the whole family of Man Ruyan", and then took out a dark green needle and inserted it into the tongue, and with the injection of liquid, the black tongue began to squirm strangely.

"Bang!" A violent thud.

The wind is blowing!

The stone demon felt his arm tremble, as if he had hit something unusually hard, and even his body felt the pain of the shock, and then he looked forward, and the black tongue did not know when a crack appeared... No! These are dark green lines!

The whole body of the student is covered with dark green lines, like a reinforcer, the whole person is a little bigger, the original delicate body is convex and different from ordinary muscles, and the black tongue full of dark green lines is even more inflated!

"Man Ruyan, I took out a protopsy that I didn't make easily to save you, and you have to forget about the perfume, by the way... Give me a few more bottles! ”

It doesn't matter whether Man Ruyan heard it or not, anyway, he said it, and she didn't deny it, so it was regarded as a tacit acquiescence.

Sheng Yanyan stepped on the floor, the floor was cracked out of thin cracks, he dragged his thick tongue and threw it over, the stone demon did not choose to defend, of course the real man wants to use the attack to defeat the attack!

The rock fist slammed out, and the two collided again, this time the stone demon took a step back, and the strengthened tongue was really much stronger, and the scene that was originally evenly matched just now immediately tilted.

The silver cold light flashed, and the dark green pupils of Sheng Yanyan moved to the side, and his left arm was quickly raised, and a blood mark instantly rushed out of blood, and the left arm covered with dark green lines was much harder, and Aya Xiaocheng didn't cut off his arm with a single knife.

However, his attack method "tongue" has been restrained by the stone demon, and now he is undoubtedly a slightly hard stone, Aya Xiaocheng kicked his left foot, held the handle of the knife with his backhand, and the tip of the knife showed the breath of death and rushed straight in!

At this time, a huge stone pillar drilled out from under the ground, and although the silver blade pierced the stone pillar, it was still slowed down.

The silver blade flicked and landed on the stone demon's throat, and Aya Xiaocheng asked coldly:

"Give me a reason not to kill you."

This time, the stone demon facing death did not tremble and beg for mercy as before, but said in a deep voice with firm eyes:

"Give him to me, you go first, and I'll stay here."

Aya Xiaocheng's writing wheel eyes moved to the left, and he glanced at him deeply with his afterglow, then put down the silver blade and said to Luo Musheng behind him:

"Luo Musheng, let's go."

After Aya Xiaocheng finished speaking, he quickly swept past the research institute and ran forward, Luo Musheng quickly followed, and at the same time glanced back at the stone demon, only to see him showing an excited wild laugh and... Endless fighting spirit.

"It's troublesome, the Heart of Huangyu is unguarded, if they take it, their free research room will be gone..."

Cold sweat dripped from time to time on Sheng Yanyan's face, as if it was very hot, but in the middle of them, a purple five-pointed star pattern appeared.

……

Aya Xiaocheng acted quickly and shuttled through this dark road, there were many doors next to him, but he didn't have time to open them one by one, and he didn't think that the heart of Huangyu would be in this kind of place, and after reaching the innermost, it was another iron door.

Something like some ID is required to open.

Aya Xiaoguo broke off and chose to "break the door without unlocking", brushed a few times, cut the door in half, and the inside was still a familiar elevator, he and Luo Musheng sat up, after the door opened, after chopping the iron door blocking the front, it was a dark passage.

Again? Is it difficult to walk several times? In this case, there will definitely not be enough time!

By the time they finished, it was estimated that the enemy's reinforcements had already reached the door of the last level, and they were waiting to open the door with machine guns.

Luo Musheng worriedly pulled Aya Xiaocheng's clothes, and his big snow-blue eyes were full of worry.

However, Aya Xiaocheng seemed to have expected it, and said lightly: "Let's move on." ”

Well, seeing Aya Xiaocheng continue to move forward without hesitation, Luo Musheng had no choice but to follow, after all, with her understanding of Aya Xiaocheng, he would not die like this.

"Two, this way doesn't work."
