The anti tank mines in Tieshan town are all powerful, because now all kinds of armored personnel carriers and some advanced tanks adopt V-shaped armored chassis. If the power of anti tank mines is not strong enough, it is difficult to penetrate the armored chassis and kill internal members.

This kind of anti tank mines with increased power are just in use after the great change of heaven and earth. They have considerable lethality to medium and low-grade monsters, because these mines will explode only after the monsters step on them, and will not give the monsters a chance to escape.

However, it is precisely because of this that the weight of these anti tank mines is also considerable. The weight of an anti tank mine reaches 10 kg. Coupled with the problem of volume, a soldier can only carry 20 anti tank mines at most.

Any more would affect the operation. One hundred soldiers carried almost 2000 anti tank mines.

"Keep quiet and move quickly. Once you find a monster, try not to make a noise and find a way to ask us for help. We will try our best to ensure your safety!"

"But this is a battlefield. I hope everyone is mentally prepared!"

"Let's go!"

Li Mu glanced at everyone and then ordered in a deep voice.

The whole team was silent and began to set out immediately. In this team, all the martial friars of Wudao University who could fight went, and Mo Lingyu and Wu Kun were also in the team. Only Zou Ping claimed to be injured and didn't start with the team.

A small door was opened on the side of the fence of Tieshan town. The whole team rushed out and walked quietly along the secretly closed minefield.

The minimum weight of these anti tank mines is generally 100 kg. It would have been OK for ordinary people to step on them, but now soldiers are carrying heavy anti tank mines. If the mines in this minefield are not closed, once someone steps on anti tank mines, the consequences are unimaginable.

In the minefield in the southeast, there was the smell of demon corpses and gunsmoke everywhere. The whole team was silent. Li Mu led the way vigilantly. Everyone tried to walk lightly and move forward quietly.

"Roar!"

Soon after, the dark silence was broken by low animal roars, and there was a slight commotion in the team.

Li Mu stretched out his hand and motioned for the team to stop. With the faint moonlight, his eyes swept through the team. The commotion soon calmed down. Then Li Mu motioned to move on.

Those monsters are still far away. They all have wisdom and know that the minefield is dangerous. They won't easily get close to the minefield unless they are driven by a big demon.

Soon after, Li Mu motioned the team to stop and start laying mines. The soldiers took out Engineer shovels and began to work immediately.

The sound of "rustling" excavation soon sounded in the minefield. Monsters can't clear the mine. These anti tank mines don't need to be buried deep, just don't need to be seen easily.

"Let's go forward and guard in front!"

Li Mu motioned more than 30 friars to separate in a fan and continue to walk outside. Doing so can make the soldiers who are burying mines safer. If the monster wants to get close to those soldiers, it must pass through their guard.

In this way, in case a single monster accidentally breaks in, they can solve the monster with the smallest movement as far as possible to prevent soldiers from being suddenly attacked and making a big movement.

"That ape demon should be there!"

Li muyue went up a half collapsed tree, and Mo Lingyu followed, took out the night vision telescope and looked ahead.

Outside the minefield, those dense monsters are also distributed according to the strength class. The core position is the great ape king. On the outside layer, there are a few shadow blood cats. Vaguely, some snake demons, cow demons and huge bear demons can be seen.

More peripheral are many shadow blood cats, flying red tigers, and even the most peripheral are iron backed wolves, pig monsters and other low animal level monsters.

These monsters are also divided into classes like people.

"If you can drop a large equivalent thermobaric bomb on the head of the great ape king while he is sleeping, it should be very possible to kill the great demon instantly!"

Mo Lingyu whispered.

There are thermobaric bombs in Chengdu fortress. Even the most common individual rocket thermobaric bombs can instantly destroy four meter thick concrete fortifications. The larger the volume, the more terrible the power of thermobaric bombs. Among them, the representative is the mother of bombs in North America and the father of bombs in tsarist Russia, which is known as a conventional weapon inferior to nuclear weapons.

However, ordinary individual rocket thermobaric bombs or small and medium equivalent thermobaric bombs can not kill the great ape king at all, while large equivalent thermobaric bombs need to be dropped by air.

But airdrop requires transport planes, and there are no transport planes in Chengdu fortress, not to mention even if there are transport planes in Chengdu fortress.

"Miss Mo, look at the top!" Li Mu whispered.

Mo Lingyu raised his night vision telescope and immediately looked into the air. In the air, several dark strange birds were circling.

"The general level monster is just like the human officials. In most cases, there are guards around, on the ground and in the sky. The plane can't get close to the top of the ape demon!"

"These monsters are more and more like people!" Mo Lingyu said anxiously.

"It is said that some big demons can become human after they are transformed. At least in terms of wisdom, they are no different from people!" Li Mu whispered.

"These monsters are powerful and have human wisdom. I don't know where our human future is!" Mo Lingyu said anxiously.

"The future of mankind lies in its own hands. It depends on itself in the future!" Li Mu looked at the time and whispered, "let's go. It's almost time. It seems that we're lucky. No monsters found us!"

Mo Lingyu nodded. Li Mu sent a signal to everyone to start retreating. When they retreated to the soldiers who laid mines, they immediately returned to Tieshan town together.

According to the plan, the operation was completed within one hour. The soldiers had 40 minutes to mine and 20 minutes to go back and forth. Once the time came, they had to return whether the mines were arranged or not.

Figures appeared quickly and returned quietly. It seemed that only slight footsteps were ringing on the ground. At this time, a large dark cloud in the sky slowly obscured the moonlight and made the last glimmer of light disappear.

Li Mu Meng stopped.

"Do you smell it?"

"What?" Mo Lingyu was stunned and looked at Li Mu.

"There is a faint smell!" Li Mu's eyes were cold and suddenly looked in the direction of the faint fragrance. There was a fine fragrance that had burned half in that direction.

"It's demon fragrance!"

Li Mu waved his fist in the air and smashed the fine fragrance silently.

"Count the number of people!"

"Three of us are missing!"

The people's faces changed greatly. They immediately counted the number. When they came, there were more than 30 people, but now there are three less.
