Underground city.

On the empty ground stands the upper part of the artificial magnetic pole. On a yellow sandy land, it looks like a magnificent tombstone.

This place has an excellent geographical location. The tall mountains on all sides block the storms and cold currents, and there is a flat plain in the middle. The geological structure is stable and solid, enough to support the construction of incredible underground fortifications. The area and capacity of this underground city can be compared with the metropolis at the peak of human development.

At the beginning, when the human base began to take shape, people predicted that if humans could resist it, then the underground city base would be the last to fall.

But now, this open plain is covered with blood. Monsters, aliens, humans, bloodstains are covered with broken limbs, severed hands, and the remains of heavy weapons.

A black fighter plane flew over the ground quickly, dropping several high-yield bombs, dull explosions sounded, and the monsters howled deafeningly, but they were soon drowned in the rolling dust.

The fighter plane rose high and circled steadily in the sky. Lu Xun held a walkie-talkie in his hand and said, "The monsters on the ground have been cleared."

Next to him was Hubbard, the legendary mercenary captain of the outer city, looking at the entrance to the underground city in the distance and said, "It's very difficult inside."

Lu Xun looked there without saying anything, tacitly agreeing with Hubbard's point of view. In the past few years, he and this captain have cooperated in commanding air battles and have established enough tacit understanding - not to mention that they were originally the kind of people who went deepest into the front line of the abyss, and no one understood the habits and lethality of those things better than them.

The dungeon is easy to defend but difficult to attack. It is a strong and safe fortress, and it has the advantage of preventing radiation. However, its structure determines that once it is breached by aliens, it will be a mess.

Now it has been breached.

"What we lack most is firepower. The birth rate is high and the troops are insufficient. We can only increase the consumption of military equipment. We overdraw too much in advance, and now we can't defend effectively." Hubbard narrowed his eyes like a falcon: "We brought enough things and arrived in time, so we still have a chance of winning."

At this time, a voice came from the intercom.

"The Underground City thanks you for your generous support," the operator said in a trembling voice, "but, out of humanitarian principles, we must inform our compatriots in the Northern Base: Currently, no contact infection has been observed inside the base, and infection can be predicted at any time and anywhere..."

"Northern Base received," Lu Xun interrupted the operator directly, "Please prepare for ground support."

Hubbard frowned.

Lu Xun said: "The flight formation will be temporarily suspended, I will take the people down."

"I'll go." Hubbard said: "According to you, it's more dangerous inside than we thought, and I'll come back after going down.

"You have no such obligation."

"But I don't have any worries. "

Lu Xun said calmly, "I didn't."

Hubbard smiled and asked, "You didn't?"

Lu Xun looked at him, and there was no emotion in his cold green eyes, but he didn't say anything this time.

"When you are asleep, you will look at the porthole for a long time." Hubbard said.

"I will leave one person at the base," Lu Xun leaned against the porthole with his arms folded, "with a bullet shell hanging around his neck that I used to kill people."

"Who did you kill?"

Lu Xun did not answer.

"Well, it's you," Hubbard said, but he seemed to remember something: "I met a boy who took a bullet shell from you and asked me if I knew where it came from."

Lu Xun hooked his lips.

Hubbard said: "Then your relationship is very complicated."

"Maybe." Lu Xun walked out: "The relationship between all my people is very complicated."

With a cold voice, he said to the navigator: "Prepare to taxi."

This time Hubbard did not stop him, but looked at Lu Xun's back, thinking.

——Under the huge, blood-red sunset in the west, the flight formation landed, the cabin door opened, and Lu Xun walked down PL1109 and headed for the city that stretched underground and was in a pool of blood.

Northern Base.

At the moment when he was about to stick the ID card on the sensor, An Zhe heard footsteps behind him. He turned around and saw that it was a routine patrol soldier led by a familiar judge.

The judge saw him and said, "Why are you here?"

An Zhe lowered his eyes slightly: "Help Dr. Ji get something."

"Is the doctor still doing research?" The judge said.

An Zhe said "hmm" softly and said nothing more. The judge did not ask any more questions, but said, "Go back early, there is military work today."

An Zhe said, "Thank you."

As they walked over, An Zhe took a deep breath and stuck his ID card on the sensor. Fortunately, the access control system was not closed yet. With a click, the door lock opened.

An Zhe pushed the door open, and the door hinge squeaked due to friction. He closed the door immediately after entering. In the dim light, the huge instrument was dark. In the center of the room, a cylindrical glass box stood quietly. A faint light illuminated the glass box from below, and a cluster of small bubbles was emerging from the ground and floating to the surface.

Anzhe held his breath and prepared for the worst before opening the door: being caught, the spores had been transferred, and others in the laboratory... At this moment, his heart completely stopped beating.

——Until his eyes passed through the glass water tank, through the light green culture medium, and saw a small white ball suspended alone in the center.

Anzhe's breathing trembled, his lips curled up, his heart beat heavily, and he wanted to rush over immediately, but because of his excessive emotions, he could hardly move.

The snow-white little thing seemed to be swimming in the deep sea in the liquid under the dim light. Anzhe blinked and looked at it.

At this moment, he saw the spores, which were originally suspended quietly, suddenly paused, and then the mycelium suddenly stretched out, or it would be more appropriate to describe it as exploding.
