Three days before the attack on the A-11 laboratory.

In the southwest corner of the mainland, three kilometers north of the SW0304 safety zone, the former high-speed rail tunnel is located here.

A few months ago, Wu Qi followed the mercenaries of the Black Gun Mercenary Group led by Wang Sheng to this place and completed a super-level exploration mission. They encountered a large number of mutant monsters in the high-speed railway tunnel, which had already been occupied by the plague species, and on the way back, they ran into the "Colossus of Destruction", and escaped from the lair at the tragic price of the death of most of the team members.

Later, Wang Sheng reported the mission report of the exploration mission of the high-speed rail tunnel to the Sirius Group. Because they didn't explore the high-speed rail tunnel thoroughly, this mission was upgraded to a B-level exploration mission, and after updating the mission information, it returned to the mission release column of the Sirius Group, and was picked up a day ago.

A convoy is traveling between tracks hundreds of meters outside the entrance of a high-speed rail tunnel. The convoy consisted of two armored combat vehicles, one armored truck, and a total of 30 people, 28 of whom were heavily armed mercenaries and 2 were pioneers.

This team belongs to the newly promoted sixth-level mercenary group, the Hell Lion Mercenary Group!

Sitting in the co-pilot of the first armored combat vehicle was a man with an angular-shaped face, three-dimensional facial features, fair skin, and dark eyes. His appearance is the type that is not easy to distinguish when thrown into the sea of people, but he has a powerful name, Lei Weiming.

Lei Weiming is the captain of the second team of the Hell Lion Mercenary Regiment, and he has the second-order ability "Electric Current", and most of the cells and organs in his body have mutated into a body with the same principle of electric eel discharge.

The all-black combat suit on his body is a special low-resistance power guidance suit. Because Lei Weiming, like the electric eel, can only discharge at full strength in the water, and on land, the resistance of the body is lower than that of air, and the discharge will be electric to itself; And wearing this low-resistance power guide suit, he can discharge at all times and at any time, and the highest record release is 1400 volts.

Powerful abilities and advanced equipment have combined to make Lei Weiming's terrifying combat effectiveness, and thousands of mutated animals and plague species have been killed by Lei Weiming in the past four years. He himself is the most powerful mercenary of the Sirius Group, and is even known as the top of the fifth-level mercenaries - because only a pioneer with a third-order ability can become a sixth-level mercenary.

Originally, Lei Weiming belonged to another fifth-level mercenary group, but later that mercenary group was seriously injured in an A-level mission, and only an empty shell remained, so Lei Weiming found another owner and hit it off with Charlotte Leroy, who was looking for a "cadre"-level role. Charlotte did not hesitate to give Lei Weiming half of the mercenary group to command, and the combination of the two also pushed the overall strength of the Hell Lion to the peak of history.

Now Lei Weiming has taken over the B-level task of exploring the high-speed rail tunnel, and has taken all the members of the second team of the Hell Lion Mercenary Group to the mission destination.

"Captain, the mission destination is ahead, drive in or stop?" The driver asked.

"Drive in." Lei Weiming said lightly.

As the convoy drove into the high-speed rail tunnel, the light of the environment was instantly reduced, and the bright lights replaced the sunlight to illuminate the road ahead in the darkness.

The high-speed rail tunnel is no longer what it used to be, and it is full of potholes. There are two reporters on the team who take photos and take notes, and write down everything they see and hear during the mission.

After a short time, the convoy reached 3,000 meters from the tunnel entrance, and from 2,000 meters, the concrete wall at the top of the tunnel had a large cavity at every distance, as well as on both sides. Through the entrance of the cave, the mercenaries discovered that the high-speed rail tunnel had already been opened by unknown creatures and the nearby mountains.

"The lair of the plague species......" Lei Weiming carefully observed the environment of the tunnel, and said silently.

If you remember correctly, the former Black Gun Mercenary Group was attacked by a large number of first-order plague species "humanoids" when they reached 2,000 meters, and the humanoid beasts came prepared to ambush them.

Could it be that in that battle, the second-level Black Gun Mercenary Regiment killed all the living forces of this plague seed lair, and left no pieces of armor left?

Lei Weiming doesn't think so, if that's the case, they will come in vain, and the remuneration is only guaranteed. Lei Wei shouted "stop", and the entire convoy stopped at his command, and more than 20 mercenaries got out of the car one after another, holding rifles to guard the surroundings.

The deputy captain walked to Lei Weiming's side as soon as he got out of the car. The vice-captain was a good-looking but not beautiful female pioneer, with the face of an oriental woman, pale yellow skin, and black hair. She is a pioneer of long-range combat, and no life form that appears at the end of the bottomless dark tunnel can escape her "infrared vision".

"See?" Lei Weiming asked.

The vice-captain said, "No." ”

"Why don't you throw a sonic bomb and blow up all the plague species?" Lei Weiming came up with an idea.

For tasks with a difficulty lower than A-level, Lei Weiming has always led the team to uphold the "reckless style". His so-called "reckless man" is not a reckless action, but a radical and efficient method supported by keen observation, decisive execution, and strong combat effectiveness.

"Then do it. All the staff listen to the order, and prepare for the use of blast bombs! ”

Lei Weiming asks a mercenary to use a sonic bomb, and the mercenary takes one out of his tactical belt, pulls the ring, and throws it towards the end of the tunnel!

All the mercenaries immediately covered their ears and opened their mouths wide. A second later, a sharp and loud explosion filled a radius of ten meters centered on the sonic bomb, and the sound spread through the rock wall and soil, awakening the plague species in the depths of the lair!

Lei Weiming lowered his hands from the sides of his ears, and he suddenly had a premonition that a large number of plague species were approaching them!

"It's coming! Many, many, at least hundred! The vice-captain said solemnly. Her vision is not only at the end of the tunnel, but also under the tunnel, behind the concrete walls on both sides, there are a large number of "red light sources" that suddenly appear.

Infrared vision cannot see through very thick walls, and these "red light sources" that can be seen mean that they have reached a very close place.

This group of plague species entrenched in the high-speed rail tunnel is moving so fast!

Bang! Bang! Bang! Bang! The continuous sound of breaking ground sounded, and a large number of humanoids broke through the concrete wall and drilled out from both sides of the tunnel and the ground, forming a black crushing patch in an instant!

"Free fire! Suppress these brutes! Lei Weiming ordered indifferently. He also grabbed a fully automatic rifle and fired at the approaching humanoids.

The rain of bullets trampled on the flesh and blood, and the team combat quality of the mercenaries of the second team of the Hell Lion was extremely high, and a mixed firepower battle line was formed in three seconds, and the black pressure of the humanoid beast group was absolutely suppressed, and at 18 seconds, the first batch of humanoid beasts that broke through the ground were all wiped out, and none of the mercenaries were injured.

PS: There is a red envelope plus more today, three more.

Xishan didn't add red envelopes for the time being after thinking about it. The line of 400 should be the last time. I didn't save the manuscript and probably added more Buddhism, mainly because I was tired o(╥_╥)o.

In the future, I will participate in the Explosion Week activities, which is equivalent to a recommendation... After all, the leaderboard has dropped, so you have to work harder!
