Qian Lao, Ahn Young-cheol, and Thomas join up with Nakai and engage in a fierce battle with the puppet creatures parasitic by Gurok.

Ahn Young-cheol discovered the mystery. He looked at the otter Yuanjun curled up in a ball on the side, and understood that the freezing gas it had unintentionally released was the key to stopping the invasion of the ancient rocks. He excitedly went over to pick up Yuanjun, but he was shivering from the cold and had to let go of his hands.

The pressure on the positions of Qian Lao and the others is getting smaller and smaller, and the beast can hardly form a threat. Once again, he shouted to Nakai, suggesting the use of liquid nitrogen.

Nakai has been indifferent, gritting his teeth and leading the soldiers to the death. In desperation, two or three more soldiers were manipulated by Gu Luoke, screaming and raising their guns to strafe in the center of the position.

At this point, one of Nakai's soldiers could no longer stand the slaughter of the Gurok soldiers, and he secretly fired a shot at the liquid nitrogen tank. Only a "bang" was heard, and the entire liquid nitrogen tank exploded, and under the white fog, the temperature of the entire position dropped sharply. The movements of the Gurok soldiers, who were killing with impunity, slowed down suddenly. Its head began to grow and shrink strangely, and a gray substance escaped from its mouth and nose.

"Look! That's the essence of Ancient Rok! Although Ahn Young-cheol and the others were still far from Nakai's position, they also saw this terrifying scene.

"Sergeant Nakai! Spray that monster with freezing air! Qian Lao couldn't help but remind loudly.

Nakai turned his back to everyone, and everyone couldn't see his expression, but they all sweated for him.

Thomas frowned and said, "This guy is a little strange, why is he delaying his move?" While reminding his mercenaries not to relax, he said to Qian Lao: "I don't understand what Nakai is waiting for, won't he be manipulated by Gu Luoke?" ”

Qian Lao was also stunned when he heard this. Before he could answer, An Yingzhe on the side preemptively said, "Impossible! Zhifei said about the situation of this Sergeant Nakai, although he did not become a complete source field force, he had a strange physique that would not be controlled by Gu Luok's parasite! ”

Qian Lao nodded and said, "Thomas, you take your people to cover me, and Xiao An and I will go over there to support." ”

Thomas stopped talking. He instructed the mercenaries to hand over two powerful weapons to Qian Lao and An Yingzhe, and then concentrated their firepower to clear a passage for the two.

Qian Lao took An Yingzhe through the battlefield quickly to Zhongjing's fortifications, only to see that the situation here was worse than it looked from a distance. Everywhere were badly wounded and groaning soldiers, and several liquid nitrogen cylinders had long since been buried by layers of beast corpses and soldiers' corpses.

Ahn Young-cheol couldn't help but vomit when he looked at the tragic situation in the position. Qian Lao said to him: "Xiao An, cheer up! I'm going to rush over to support Nakai, you dig up the liquid nitrogen bottle here and open it! ”

Ahn Young-chul cried and cried, he had never experienced such a scene, and cried out in a broken heart: "No, no! I can't! ”

Qian Lao said loudly: "It's too late to be hypocritical!" You'll have to move away from the corpse and find the liquid nitrogen! Otherwise, everyone here will die! As he spoke, he grabbed Ahn Young-chul's hands and glared straight at him.

An Yingzhe gradually calmed down, he took a few deep breaths, and motioned for Qian Lao to let go of his hand. "Old Qian, go and help! I'll help when I find liquid nitrogen! As he spoke, he unleashed a large cloud of flame from his hands and burned towards the corpse

"I don't dare dig up the body, but I can put a torch and burn the cylinder buried in it until it explodes!" Ahn Young-chul said.

Qian Lao nodded approvingly, patted An Yingzhe's shoulder again, and turned around and ran towards Zhongjing's position.

An Yingzhe looked at Qian Lao's back, and an uneasiness suddenly rose in his heart. He didn't think much of it, and turned around to shoot a hot flame at the cascading corpses.

Qian Lao's skills were extremely agile, and while he was dodging the beasts that had come to him, he was able to help other soldiers break the siege, and gradually approached Nakai's location. He found Nakai just out of reach of the liquid nitrogen bottle that had exploded, and he was struggling with a puppet soldier manipulated by Grok. The soldier was so powerful that he could easily grab Nakai's body with one hand and drop it to the ground. The surrounding soldiers wanted to shoot to help, but they didn't dare to throw a rat trap.

Qian Lao was anxious, he saw that Zhongjing seemed to be at the end of the crossbow, but he was lucky not to be hit by the point.

"Quick! You guys go over there as soon as you can and help find the liquid nitrogen! I'll take care of it here! Qian Lao said to the few soldiers around him who were only slightly injured, he stabilized his body and aimed at the head of the Gu Rok soldier to shoot a few points.

"Whew!" The Gu Rok soldiers, whose heads were almost shattered by bullets, finally gave up on Nakai and turned to pounce on Qian Lao.

Qian Lao stepped back calmly. He smashed the guns scattered on the ground one by one as he shot at the joints of the Gruk soldiers. To his surprise, even if his knee joint was shattered, the Gurok soldier was still able to move quickly and was completely unaffected.

"Oh no, that's a problem." Qian Lao was secretly frightened. In desperation, he could only use the terrain of the fortifications to constantly play hide and seek with the ancient Rok soldiers. In this way, the Gurok soldiers had no way to take the money for a while. But Qian Lao's bullets were also unable to pose a threat to the Gurok soldiers.

Suddenly, as if realizing something, the Gurok soldiers stopped chasing Qian Lao and turned their heads to run towards Nakai, who was still gasping for breath on the ground.

Seeing this, Qian Lao was very anxious, and hurriedly shot at the pillar of the fortification on the side of the Gu Luo soldier. The pillar fell with a bang, crushing it right under him. Qian Lao quickly ran past the ancient Rok soldiers towards the unknown Nakai.

"Sergeant Nakai! How are your injuries? Qian Lao looked at Zhongjing who fell to the ground with concern, but found that his face was strange, and he didn't seem to be hurt except for some stains on his body.

Nakai slowly sat up and said slowly, "I'm fine." I don't need you to come and help. ”

Qian Lao also felt that Zhongjing's words and deeds were weird, but he only thought that he was troubled by his self-esteem and couldn't let go of his face.

Suddenly, the Ancient Rock soldiers, who were crushed in the rubble, suddenly broke out of their trap and rushed towards the two of them with a strange scream.

Qian Lao raised his gun to shoot, but found that the bullets had run out. He hurriedly pulled up Nakai and said, "Run!" ”

Nakai also seemed to finally realize the urgency of the situation, and followed Qian Lao to run wildly. But the speed of the ancient Rok soldiers was even faster, and without the harassment of firearms, they gradually narrowed the distance between them and the two. And Nakai didn't know why his pace gradually slowed down.

Qian Lao noticed that Nakai was lagging behind, thinking that he was injured, so he had to slow down to answer him. Unexpectedly, the Gurok soldier suddenly exerted his strength, jumped up, landed on the two of them, and smashed his fists the two of them.

Qian Lao and Nakai were thrown up by a huge force and fell to the ground again.
