135: Smoky crystal bullet!

As they spoke, a crisp beep sounded, followed by the sound of rushing air from beneath the ground, and the door began to open slowly from the middle.

"This is actually a pneumatic door!"

As the door opened just enough for one person to pass, Ling Chao was the first to crowd forward.

"Boss! Inside is a tunnel!"

After confirming it was safe, Ling Chao ran in first, followed by Li Xiao, who crossed the door second.

Just as he had guessed, the door was half a meter thick; it was definitely nuclear-proof.

Everyone filed in, while the enemy's bullets pattered against the wall behind them. Zhou Shuang entered last, having closed the door again before doing so.

The tunnel seemed to be in an emergency state; the emergency lights on the walls were all red. Everyone turned on their tactical flashlights and moved forward.

Just after turning a corner, two Gatling heavy machine guns suddenly opened fire. Ling Chao and Chen Hu were immediately knocked to the ground by the inertial force of the dense bullets.

At this moment, Li Xiao was quick-witted; he pulled out a rocket launcher and fired a shot, immediately silencing the heavy machine guns.

Chen Hu charged ahead, only to find that besides the corpses of two Black Hawk soldiers, the tunnel was blocked by another electric gate.

However, this did not dishearten them. Zhou Shuang, who had already successfully breached the base's firewall, opened the gate in just two minutes.

Behind the gate were three elevators. According to Ling Chao's judgment, the three elevators should all be universal. He pressed the down button, the elevator door opened, and what met their eyes was a massive elevator nearly twenty square meters in size.

At the elevator entrance, Li Xiao noticed that there were actually six underground levels in total!

They opened the middle elevator and went straight to the first underground level.

Ten seconds later, with a "ding," the elevator door slowly opened, but the first thing they saw was not the scene of the first underground level, but dozens, if not hundreds, of dark gun barrels.

"Fire quickly!"

Chen Hu shouted, but it was already a second too late. In an instant, they were subjected to a rain of bullets, and the entire Shadow Squad was driven back into the elevator by the gunfire.

Ling Chao saw that things were going poorly and casually pressed the elevator close button. Countless bullets were soon blocked by the alloy elevator doors.

Li Xiao hurriedly checked everyone's health status and found that in this half hour, their health had been depleted to around five million.

"Everyone, get your grenades ready. Watch me!"

Li Xiao took out a quad-barrel rocket launcher. In this situation, only a heavy weapon could break through their defense.

The elevator door opened again, and those outside were already eagerly firing to suppress them. When the door opened half a meter, the six of them, including Ling Chao, simultaneously threw a grenade.

But they didn't expect that the Black Hawk Unit had the same idea; instead, dozens of grenades flew into the elevator.

Two seconds later, a violent explosion occurred inside and outside the elevator. Li Xiao was blown up by the grenades on the spot so badly that even his own mother wouldn't recognize him.

Fortunately, the pain was only temporary. After the explosion, Li Xiao angrily grabbed the quad-barrel rocket launcher and fired wildly outside.

The explosive power of the rockets immediately scattered the surrounding Black Hawk Unit. Chen Hu rushed out first, holding his long-thirsty squad machine gun and sweeping wildly.

However, these Black Hawk Unit soldiers in the base were clearly better equipped and had higher ranks; even after firing all 150 rounds, they had only killed a dozen or so people.

But when it came to trading health, Li Xiao had never backed down. Everyone stood their ground and fought, and within a few minutes, they had wiped out this group of Black Hawk Unit soldiers.

Stepping over the blood-soaked corpses, Li Xiao finally saw the structure of the first underground level clearly.

He didn't know until he looked; one look and he was shocked. The Black Hawk Empire had actually excavated a space here as large as a main stadium and four meters high.

They had set up a complete equipment manufacturing assembly line here, and countless robotic arms and robots were still running at this moment.

Li Xiao carefully examined the equipment on the assembly line. They were sci-fi-looking and peculiar new rifles. Li Xiao was certain they were completely different from traditional weapons.

The efficiency of this production line was very high, basically producing more than two rifles per minute.

"Tsk tsk... As expected, a military factory operated by a state machine is fierce."

Without giving them much time to breathe, the elevator door opened again, and another group of Black Hawk Unit soldiers rushed out. This time, they could calmly deal with the remaining enemies.

After dealing with the enemies on the first level, they immediately went to the second underground level.

The second level was still a factory as large as the first, but the difference was that this was an ammunition production line that had stopped running.

The automated assembly line had no staff, only robots. Li Xiao came to the terminal of the assembly line, where there were boxes of packaged ammunition.

With sharp eyes, he suddenly discovered that these bullets were a bit strange. Traditional bullets consisted of propellant and a warhead, but the bullets in front of him had no casings; instead, they were compression-molded with an ink-colored crystalline substance wrapped around the warhead.

This reminded him of a new type of caseless ammunition that had long been available on Blue Star; these two types of bullets were made in the same way.

However, the Blue Star type was compression-molded solid gunpowder, while this one was an object shaped like a black gemstone.

"What kind of bullet is this?"

Li Xiao picked up a bullet and soon discovered he could open its information panel.

5.8mm ink crystal rifle bullet: A new type of ammunition that uses energy-rich ink crystal as the propellant energy.

Special: Using ink crystal bullets can greatly increase the range and accuracy of firearms, while also providing powerful warhead kinetic energy.

Attribute: Fired using a specialized crystal energy gun, effective damage is 350 points.

"Damn!"

Seeing the damage of the ink crystal bullet, Li Xiao was stunned. 350 points of damage per shot! Almost five times the damage of the QBZ series rifles!

"Oh my god..."

He held the ink crystal bullet in front of his eyes and looked at it: "350 points of damage, how can heavy machine guns even compete?"

Li Xiao didn't hesitate to immediately load all 50,000 ink crystal bullets on the scene into his backpack. He hadn't noticed earlier on the first level, but now it seemed that those rifles were specifically designed to fire this kind of bullet.

"Go to the third level!"

Seeing the appearance of the ink crystal bullets, Li Xiao immediately felt that this trip might have been the right choice, but that didn't mean he would be satisfied with just getting 50,000 ink crystal bullets.

As soon as he entered the third level, Li Xiao immediately felt something was wrong, because on the five-meter corridor at the elevator entrance, countless intertwined red light beams were constantly and orderly rotating.

Li Xiao had seen too many such laser arrays in movies; it was rumored that touching the laser beams would sever arms and legs.

He casually took an AK rifle out of his backpack and reached out to test it. The result was that these laser beams were just ordinary laser rays.

But just as he thought this, the next second, a jet of water suddenly sprayed out. Before Li Xiao could react, he saw that the AK had already been half-melted, both the steel and the wood.
