In the emerald green night vision device, Situ Kong could clearly see that in the hall on the ground floor, there were more than a dozen armed guards wearing chemical protective suits and gas masks!

And those three elevators, which are powered by the backup power distribution room and can lead directly to the underground laboratory, are still sending the armed guards in the underground laboratory up!

Luo Hao looked at the armed guards in the hall on the ground floor, who were nearly five times the number of people around him, his eyes locked suddenly, and he grabbed Situ Kong and dragged him up the stairs.

"Dada......"

Dense bullets landed on the wall behind where Situ Kong was standing just now! Looking at the walls that had been torn off by bullets in an instant, cold sweat instantly soaked Situ Kong's back.

"Is this a drug laboratory or an android factory underground, why are so many people suddenly popping up!" Situ Kong scolded.

Troops!

Inoue Oka has increased the garrison of the Chida Medical Research Institute, and it is a secret increase in troops in a way that is unaware of the ghost and evades the monitoring of the members of the special service team!

"Master, let the meridian instructor check if there is any other entrance to the underground laboratory, the number of armed personnel in the Qiantian Medical Research Institute has exceeded our expectations!" Luo Hao contacted Zhao Tianyu through the headset.

"I'll get back to you in five minutes!"

"Damn, there are so many people, it's hard for each of us to rush through even if we have three heads and six arms!" After Zhou Bai shot out several armed guards approaching the stairs with a long shot, he said to Luo Hao.

"Don't think about it, but you can try my new gear!"

Lin Xiaoyang handed Luo Hao two cluster grenades that were screwed on the basic module, with a steel ball-type expansion module and a manganese steel nail-type expansion module respectively, "Give them something fun!" ”

Luo Hao threw the HK416 in his hand behind him and yelled at Situ Kong and Zhou Bai: "Fire cover!" ”

"Da Da Da ......"

"Da Da Da ......"

Under the cover of the fire of the two HK416 automatic rifles, Luo Hao took advantage of the cover of darkness to jump down the stairs like a cheetah, and at the moment when his body landed, his legs kicked the ground, catapulted behind a marble pillar on the left side of his body, pulled away the cluster grenade in his hand, and threw the cluster grenade towards the armed guards in the hall with his hand, and then tightened his body and hid behind the pillar.

"Boom!"

"Boom!"

The base modules on the two cluster grenades exploded first, covering the more than twenty armed men in the hall with the first round of steel ball fire.

The two expansion modules installed at the tail of the base module were directly shaken out by the impact of the explosion of the base module, and then in the crowd that had already caused a riot, they paused for less than a second and exploded!

"Boom! Rumble! ”

"Boom! Rumble! ”

The steel ball-type expansion module and the manganese steel nail type expansion module, screwed on the tail of the two base modules, exploded almost simultaneously!

Two thousand six hundred thin steel balls with a diameter of two millimeters, mixed with more than a thousand manganese steel nails, radiated to the entire hall at an astonishing high speed, carrying out a new round of fire coverage.

Although these armed guards all wore gas masks on their heads, how could that thing resist thin steel balls and manganese steel nails moving at three or even four times the speed of sound?

The moment the gas mask on the face of the armed guard was hit by the thin steel balls, it was broken by the steel balls, and several thin steel balls left several deep blood holes on the faces of the armed guards, and after a few seconds, dark red blood gushed out of those blood holes and poured into the coveralls.

Behind the marble column, Luo Hao tightened his body and leaned on the pillar motionless, for fear that if he moved, he would also be hit by thin steel balls or manganese steel nails

When the firelight from the explosion of the cluster grenade dissipated and the hall on the ground floor returned to darkness, all that filled the ears of Luo Hao, Situ Kong, Zhou Bai, and Lin Xiaoyang was the scattered spitting of the armed guards.

"Boom! Boom! Boom! ……”

The power supply in the main building of the Institute of Medicine has been restored with the work of the power supply system in the backup distribution room, and the entire hall on the ground floor is as bright as day.

Luo Hao walked out from behind the marble pillar, and when he saw the armed guards who fell to the ground, he suddenly felt his scalp tingle.

The armed guards who had been gathering in the hall on the ground floor had all fallen in a pool of blood at this moment, and their chemical protective suits were stained with blood, some of which were their own and those of others. Of these, only a few can still make snorting sounds in their mouths.

In the explosion just now, only a very small number were killed by the blast wave of the grenade explosion, and the vast majority died under the thin steel balls and manganese steel nails.

Although Luo Hao had already anticipated the explosive effect of the grenade in his heart before throwing out the cluster grenade, Luo Hao was still shocked when he saw the actual killing effect of the cluster grenade!

Two cluster grenades directly knocked nearly thirty armed guards to the ground, and such a lethal effect can no longer be explained by two "1+1+1=3". This is killing, merciless killing!

"Dada! Dada! Dada! ”

When Luo Hao walked to the underground laboratory, he bent down and picked up an AUG assault rifle from the ground, and shot at several armed guards who were embedded with dozens of thin steel balls and more than a dozen manganese steel nails all over their bodies, but died instantly because they were not hit in the fatal parts.

For these armed guards who have been injured by steel balls, and even manganese steel nails have entered their veins, and they no longer know which corner of their bodies they have drilled, Luo Hao's supplementary gun shooting is more like a relief.

At least when Luo Hao pointed his gun at the armed guard at the elevator entrance, Luo Hao saw a relieved smile on his face.

"Dada!"

Luo Hao pulled the trigger with a cold expression, and sent the last two bullets from the AUG assault rifle magazine in his hand into the eyebrows of the armed guard.

"Silly boy, the matter you want to investigate has a result!"

Zhao Tianyu's voice suddenly came from Luo Hao's headset, "Your guess is right, there are indeed other entrances that can lead to the underground laboratory of the Qiantian Pharmaceutical Research Institute, I will send the model map to your PDA!" ”

"The core of the Chida Pharmaceutical Research Institute is this underground laboratory, so when this underground laboratory was built, two tunnels were left that could directly lead to the underground laboratory. If the underground laboratory is attacked by armed forces, the Neon Nation military can use the rail train to send reinforcements directly to the underground laboratory through these two tunnels! And the entrance to these two tunnels is on the other side of the mountain! This is also the reason why Inoue Oka was able to conceal the surveillance of the special service team and increase troops to the underground laboratory! ”

Situ Kong looked at the two tunnels connecting the mountain and the underground laboratory on the PDA, and couldn't help but smack his lips: "It's really an incomparably huge project!" ”
