The violent roar of the six-barreled aviation machine gun resounded throughout the laboratory, and the tongue of flame ejected from the barrel was one meter long. In just a short moment of firing, hundreds of bullets blasted towards the only door of the laboratory like a torrential rain. Shoot the rock spiders that keep pouring in until they are smashed into pieces.
The five-story laboratory has only one door, and the others are solid walls, so it is not afraid that the rock spider will come out from other places. This restrictive secret room terrain is the favorable environment for aviation machine guns to exert their greatest power. It's just that the bullet chains from the Tyrannosaurus continue to decrease, and this advantage cannot last for too long.
The fire suppression of the machine gun was very good, but after all, it could not achieve all-round suppression, so some lucky rock spiders passed the barrage. However, if it is placed in the frost area at the entrance early in the morning, the rising cold air will greatly weaken the rock spider's mobility. So a long sword was as fast as thunder, and every time a white light flickered, the head of the rock spider was dislocated.
The long and narrow blade precisely cut through the black jelly between the rock spider's chest and abdomen, cutting them into pieces one by one.
The woman holding the long sword, after several quick and accurate slashes, made a high-position slash gesture. Her slender arm raised the long sword high, and then swung it down instantly. A sharp wind whistled in the air immediately, and invisible fluctuations swept towards the gate, and even a white dust smoke was dragged out from the ground, and the rock spiders at the gate were silently split into several pieces. Fluffy yellowish-brown blood burst out, and the ground was a fragmented corpse.
Su, who specializes in fifth-tier cold weapons, used her unique skill "wind pressure cut", showing her master-level strength. This invisible skill of the sword made Zero who was hiding on the exhaust pipe and watching the battle through the fence feel palpitated.
"What an amazing woman, she can already use the unique skills of weapon specialization. Her specialization ability on that long sword should have reached the fifth level." Ben's affirmation explained from another aspect toxin hazards.
And after sending out a wind pressure slash, Su's face remained unchanged, but his back movement was obviously slower. It can be seen that this technique also consumes a considerable amount of her physical strength.
Seeing the rock spiders that were still rushing towards the laboratory, Su had already started to regret.
Originally, she and the other two men were only drawing a map, finding the rock spider's nest, and at most capturing a few living specimens to bring back to Remut. But the three of them walked together, and the combination of different abilities made the rock spiders who met them not spared. As a result, the original self-confidence began to swell. When self-confidence turned into arrogance, the three decided to try to wipe out the rock spiders in the entire university city.
But they didn't expect that there were too many rock spiders. After they started the battle, more and more rock spiders appeared from the shadows, and they joined the battle circle, consuming the physical strength and other abilities of the three of them infinitely.
Now, they are in crisis. Although the number and movement of the rock spiders were restricted by using the terrain of the laboratory, the ammunition of the Tyrannosaurus rex was almost exhausted. With the continuous fighting, Raff's mental strength has also reached a critical point. As for Su, although she saved the strength of each shot, her beating heart like a bellows told her that her physical strength had almost reached the bottom.
"No, we'll die of exhaustion if we continue like this!" The Russian shouted: "Tyrannosaurus, Su and I temporarily suppress the spider group at the gate. You blast the wall behind, we have to go, get out of here immediately! "
The tyrannosaur didn't talk nonsense, the gun head turned around, and it slammed towards the rear wall.
Laf and Su acted at the same time.
Frost visible to the naked eye formed above the spider colony at the door, and the frost continued to condense into ice cones, and then fell towards the spider colony one after another. The sharp ice cones pierced the rock spider's hard shell, and after the impact and explosion, the released frost gas was not lethal, but it greatly slowed down the rock spider's movements. This five-meter-diameter "frozen field" is the biggest ultimate move that Raph can use at the third level of water element proficiency. It has both killing and auxiliary abilities, and temporarily makes up for the fire suppression vacated by the Tyrannosaurus rex.
And Su also rushed forward at the same time, with the long sword in his hand under the influence of the second-level strength and agility mastery, he continued to make powerful and rapid slashes, killing the rock spiders that were trying to crawl in from the frost field.
The sound of the wall collapsing came from behind, and Su knew that the retreat was imminent. The cold light rose in the eyes, the long sword flickered twice in a row, and the two wind pressure cuts crossed and blasted towards the entrance of the gate. Amidst the sound of the wind and the explosion, an "X"-shaped crack suddenly appeared on the wall opposite the door, and a dozen or so rock spiders exploded into pieces silently.
The invasion of the rock spider was temporarily prevented, and Su knew it was not suitable to stay for a long time. The slender feet stomped on the ground, and they had to use their strength to back up. However, two frost spears suddenly rose from the ground, stabbing out from the lower abdomen of her thigh in an instant, stopping her movement.
Su Su's pupils contracted, and he looked in disbelief at the person behind him who he called his "companion" a second ago.
"Sorry, we need enough food to hold back these greedy things. We will remember your sacrifice." Raff said sorry, but there was no apology on his face. He quickly jumped out of the gap in the wall blasted by the Tyrannosaurus, and an icy road appeared out of thin air, supporting him to fall towards the open space downstairs.
As for the tyrannosaurus, it jumped directly out of the building, then shrank its body, hugged the machine gun tightly and fell to the ground like a shell. After smashing a shallow hole, the man stood up as if nothing had happened, and then ran towards the outskirts of University City with Raff.
Su withdrew his gaze, and the frost spear on his body had already melted. The ice water mixed with the hot blood in her body flowed all over the floor, and the strong smell of blood stimulated the rock spider's senses. She knew she couldn't go anywhere, the blood would attract countless rock spiders, and the penetrating damage to her feet and lower abdomen made her not have enough strength and speed to leave this place.
As a result of being out, the only way to end is death. Su wasn't surprised that anything could happen in the wilderness, even if Raff didn't betray her. When necessary, she would not hesitate to use those two men as shields in order to survive. The difference is that she was betrayed by the other party first.
The long sword was received in front of the chest, reducing the radius of the slash to increase the power of the attack. Although she couldn't see any hope, Su didn't intend to give up. Born in the wilderness, it has long been instinctive for her to fight against fate.
Zero, who was hiding on the exhaust duct, looked at this scene, and his heart moved slightly.
