"Come in!" Liu Xingyu's loud voice echoed in the tent, and he sat up in good spirits, expecting the adjutant to bring good news. Pen "Fun" Pavilion www.biquge.info

Chen Jun walked up to Liu Xingyu, gave a standard military salute, and said: "Report! The second echelon has been prepared, and the soldiers are eager to fight and ask for action! Please instruct!"

After the first echelon went down to the pit, the second echelon had already entered a state of preparation, and more than 80 young men who were alive and well, loaded with guns and ammunition, were gearing up, just waiting for an order.

So far, there has been no news from the first echelon, and the wireless signal under the sinkhole has been inexplicably swallowed, and it is impossible to get in touch with them. The adjutant did not bring hopeful good news, and Liu Xingyu, who had been on the battlefield for a long time, was very disappointed.

This special battle is different from the past, because they are not facing living humans, but unknown creatures and people who have come back from the dead.

On the battlefield, the enemy's thousands of troops are not terrible, but the unknown enemy is terrible. You don't know when it appears, you don't know its weaknesses, you don't even know what it's fighting for.

Liu Xingyu's brows furrowed again, and he suddenly raised his arm with green muscles, and was about to give an order to act, when suddenly a sentence that Professor Zhao had advised appeared in his mind: 'Facing the fear of the unknown, it's just because we don't know enough.' ’

The first echelon is the elite of more than 60 dragon sword brigades, which can be described as one of the most elite troops in China, and their life and death are uncertain.

Liu Xingyu is not Zhao Kuo who talks on paper, his mind is racing in an instant, and he has made up his mind that he will resolutely not send a soldier or a pawn until he understands the weaknesses of those creatures.

He slowly lowered the arm that was parked in the air: "Pass my order, the second echelon will stand by in place, and strengthen the vigilance at the edge of the sinkhole!"

Chen Jun was immediately deflated when he heard this order, but he couldn't show it on his face, he stood up and said, "Yes!" and turned around and walked out of the tent.

Liu Xingyu added: "Arrange a helicopter brigade to airdrop a battalion's supplies and equipment to the bottom of the sinkhole!" He said in his heart, hoping that these can help you!

In the past few days, reconnaissance planes and drones have been dispatched to reconnoiter in sinkholes, and every time they fly 50 meters below the ground, that is, at the signal shielding point, the plane loses contact. Therefore, the underside of the sinkhole was listed as a forbidden area by the flying troops.

The terrain below the sinkhole is basically the same as the last time Long Lei Yan went down, with large mounds like steamed buns, mud pits and puddles all over the place.

The courtyard wall in the thick fog stood next to the bottomless ravine, and through the thick black liquid in the misty ravine, it overflowed outward, and in the huge black vortex, it kept drilling outward, the living dead and dark creatures.

Inside the courtyard walls, however, the outer building area of the laboratory was transformed into a blazing battlefield.

Countless chains of fire erupted from the windows of the buildings, and bullets flew from the rooftops from time to time. Li Xiaojian stood on top of one of the tallest buildings, using a high-powered telescope to observe the surroundings.

Thousands of living dead in kimonos slowly approached the buildings. In the main building of the laboratory, there were also scattered living dead people in white coats surrounding them.

The chain of fire swept over the living dead at the front, and their bodies trembled, and in an instant, they shattered into countless pieces like ripe watermelons. There were also living dead people who were interrupted by the waist, dragging a purple-black intestine, slowly crawling forward.

Small dark creatures, using the living dead as meat shields, lurk underground, between the legs and feet of the living dead, and once they approach the building, they burst out like black lightning, revealing their sharp claws, and pounce on the team.

At this moment, they can only be repelled by a dense rain of bullets, these dark creatures are extremely durable, and often a few bullets on their bodies can make them retreat.

The operation was mainly reconnaissance, so the weapons of the squad were all small-caliber weapons that they carried. At that time, biological scientist Wu Zhen did experiments and found that a steel-core warhead at close range could shoot through the skin of dark creatures.

Thankfully, the team was equipped with a large number of steel-core warheads, otherwise they would have suffered all casualties at this point.

The situation in front of him made Li Xiaojian's face full of solemnity, he put down the binoculars, leaned against the fence on the roof, and recalled what happened today.

The team of thirty-two people descended to the sinkhole without any danger, and the team immediately divided into ten combat teams to reconnoiter the terrain, and there was no danger except for finding some bones.

After sampling the bones, a three-person team was left behind to guard the elevator cables. They continued to explore, almost as if they were training on a regular basis, and reached the wall with great success. Some brothers even joked: "This time, it is too hard to see us from above, and give us a holiday for sightseeing!"

This time, in order to cope with the complex terrain under the sinkhole, they borrowed four jet motorcycles from the brother unit Giant Crocodile Special Brigade.

With the powerful impact of the jet motorcycle, he crossed the bottomless ravine and came to the bottom of the courtyard wall.

There were no living dead or dark creatures on the ground, and there was no whirlpool under the ravine that Professor Zhao said, and there was a dead silence around the entire sinkhole except for them.

Teams 1 and 2 jumped over the fence and advanced towards the lab. Most of them had worked in the laboratory and were very familiar with the terrain inside and outside the walls, and after a while, one by one safety reports reached Li Xiaojian's ears.

Li Xiaojian acted very steadily, and left a team outside the wall to respond, and the other eight teams all entered the wall to clean up the laboratory.

At this moment, the anomaly protruded, and the pathfinder team opened a bungalow, and suddenly a human in a white coat burst out.

The team leader had worked in the laboratory, and he actually knew this person, so he subconsciously said hello: "Li Gong, you are not dead! I am Xiao Liu!" The other two team members also relaxed their vigilance.

Suddenly, Li Gong pounced on the captain, bared his sharp teeth and bit down on his neck.

The team leader was agile, lifted his knee against Li Gong's lower body, took advantage of the gap between the other party's pauses to throw off his arm and turn behind him, and grabbed his arm with a grappling technique.

One of the two team members guarded the surroundings, and one stepped forward quickly and tied Li Gong's arms with a capture rope.

The two of them breathed a sigh of relief, thinking to themselves that this is the legendary living dead? Suddenly, Li Gong twisted vigorously, and his two arms snapped like the arms of a doll.

Li Gong opened his big mouth and gnawed the captain's leg. The captain roared angrily, aimed at Li Gong's neck and opened fire, a string of sparks, Li Gong's head was separated, and his body lay on the ground and never moved again, but his head was still hanging on the team leader's leg.

As if it had been agreed in advance, the fog in the bottomless ravine gushed outward, and a huge black vortex appeared out of thin air, blocking the way for a moment. (To be continued.) )
