"I aimed at that 'mouth' at first, but it was useless." The Hound's head shook slightly on the helmet. "The bullet was like hitting cotton... I guess it was melted by the acid secreted."

"Then there is only the first way." Ke Lan said, "I'll let Zhuo Ligetu cooperate with you. The shotgun has a larger impact area, and it will be easier for you to catch up."

"Okay." The Hound nodded and raised his arm.

"Zhuoligetu! Aim at the chest and abdomen of the one in front and shoot, three-shot mode, try firing two rounds first!"

"Understood!" The sturdy Mongolian man took a step forward and placed the heavy gun shield directly on the ground - "Bang! Bang! Bang!" The dull gunshots unique to the heavy shotgun continued to echo in the tunnel, and hundreds of steel balls poured out from the muzzle in less than two seconds!

The densely packed steel balls hit the "Anemone Head" with terrifying kinetic energy. It staggered back two steps, and a large purple-red "bruise" suddenly appeared on the part hit by the bullet.

But just when Zhuo Ligetu was about to launch a second round of shooting, it actually lay down with its front legs on the ground and its waist lowered - in this way, the frontal area exposed to bullets suddenly became about one-fifth of that in the standing state.

Ke Lan couldn't help but frown. Just as he had expected, these guys' IQs were definitely not low, especially in terms of fighting skills.

"At this angle, I can't hit the same place as before. What should I do?" Zhuo Ligetu loaded three new rounds of ammunition into the magazine and pulled the gas pump hard.

"Change to shooting at the right shoulder, still two rounds of six shotgun shells." Ke Lan said. Although the three shots just now also caused that kind of purple-red "bruise", the color was much lighter than that caused by the electromagnetic bullets used by the hound, and there was no change to pink during the "fading" process.

It seems that this defense mechanism can also adjust itself according to the strength of the attack. Although the power of the shotgun shooting looks amazing, the kinetic energy of the ammunition is much weaker than that of the electromagnetic bullet in the steel needle style when it is distributed to each steel ball... It's like boxing. A lightweight boxer hits the opponent with multiple jabs in a row. As long as the opponent defends properly, it is difficult for the attacker to find any opportunities, and even fall into a disadvantage due to excessive consumption of physical strength. But if it is a heavy punch that gathers the whole body strength of a heavyweight boxer, even if the defender successfully blocks it, he will have to recover for a while. During this time, he will definitely not be able to take a second punch of the same strength.

That strange purple-red color should be some kind of connective tissue gathered under the skin, which can absorb the powerful kinetic energy of the bullet. However, Ke Lan believes that no matter how fast this thing is generated, it will definitely have a limit. As long as the intensity of their attack can exceed this limit, they will be able to break through their defense.

"Bang! Bang! Bang!"

The roar of the heavy shotgun sounded again, and the shoulder of the "Anemone Head" lying on the ground suddenly turned a sudden purple-red. But at this time, those "Anemone Heads" that had been spitting acid at a distance suddenly rushed towards Ke Lan and the others as if they had received some orders!

"Are you planning to engage in hand-to-hand combat?" The Hound growled, stopped shooting, and pulled out from behind a thermal heavy sword specially equipped for close combat with power armor. With the infusion of crystal energy, a dark red light appeared on the blade.

But before he could rush forward, the energy shield in front of him began to flicker unsteadily, as if it would disappear at any moment...

"We have to retreat now!" Layton saw this and shouted loudly to Ke Lan and Hound standing in front, "The energy shield is about to overheat and explode! Ke Lan! We don't have time!"

"Retreat! The hound and I will cover you, those who are not wearing armor retreat first!" Ke Lan did not hesitate and threw two grenades directly at the "Anemone Head" that rushed up -

The grenade was hit by acid in mid-air before it fell into the monster pile. Two balls of fire exploded in mid-air, with almost no blocking effect.

"Ke Lan, signal the people outside to send reinforcements in, otherwise, we will all die here!" The Hound retreated while shooting at the monsters that were getting closer and closer. His energy shield had shrunk to the point where it could only protect the vital parts of his body. The right arm armor exposed outside the shield was hit by the acid sprayed by the anemone head two seconds ago. Fortunately, he reacted quickly enough to cut off the connection between the arm armor and the torso in time and pulled the arm out.

"I know, I'm doing it... Hello, this is the No. 7 Mine Exploration Team, communication code 001, we are attacked by unknown creatures, requesting reinforcements, we-"

"Why did you stop? Keep calling!" The old dog turned around in confusion, only to see Ke Lan's face was pale, which made him feel depressed for no reason...

He grabbed Ke Lan's arm and asked, "What's wrong?"

"The communication was cut off just now." Ke Lan said word by word.

"…Is there something wrong with the line?" The hound still held on to a glimmer of hope.

"No." Ke Lan shook her head. "There was no problem with the communication, but right after I said the words 'request for reinforcements', the communication was cut off."

"Damn... No way..." Before the Hound could finish his words, several explosions suddenly came from far behind, and then the entire tunnel began to shake violently!

Ke Lan didn't say anything, but he and Hound had already guessed the source of the explosion...

Manstein betrayed them and used siege tanks to blow down the entrance of the tunnel, burying them alive in the mine along with the group of "Anemone Heads"!

"Cyka blyat!!" Even Dr. Ivan, who rarely swears, couldn't help but swear.

"What should we do? What should we do now?" There was a hint of panic in Leighton's tone. He looked at the hound and then at Ke Lan.

"Let's retreat to the mining area first." Ke Lan made a prompt decision. At this moment, the "Anemone Heads" in the front had already closed the distance to less than 30 meters despite their fierce firepower. Ke Lan could even see the densely packed flesh teeth in their "mouths". These flesh teeth kept wriggling, as if they were craving for fresh flesh and blood...

"Keep the original retreat plan... Damn it, could Liao Zilang have been killed?" Hound didn't really care whether the female secretary Yui was dead or alive at the moment, but he knew that if Liao Zilang was still alive, he would definitely not watch Manstein order his men to seal the mine. So it seemed... this old subordinate of his was probably in danger.

"Old dog! Now is not the time to think about this!" Ke Lan shouted at the hound, "If you want to avenge him, at least we have to get out alive first!"
