Luo Lei obeyed Niu Zhiyuan's order and immediately checked his personnel, there was no redundant personnel, and there was no one less.

"It shouldn't be! Is it really just a chance power outage? After Niu Zhiyuan listened to Luo Lei's report, he did not relax, but frowned tightly.

"Brother Chen, is there any ...... in the monitoring" Niu Zhiyuan asked Chen Lele through the headset before he finished speaking, and suddenly remembered that there was a power outage, and the monitoring naturally didn't work. And then he remembered that the elevator would not be used, the enemy would not be able to reach the underground research room at all, and even if he reached the bottom, the metal door would not open.

No, judging by the actions of the enemy today, their goal has changed, and they no longer want to grab the research results, but want to destroy the underground research room and kill all the researchers, so as to directly block this research in our country.

This thought flashed through Niu Zhiyuan's mind, and he became more and more sure that the enemy might have somehow passed through the blockade of the armed police force and entered the No. 2 office building in the first ten seconds after the lights were turned off.

Thinking like this, Niu Zhiyuan went down from the roof to the third floor, and then walked silently to the second floor.

Suddenly, he heard an almost inaudible voice, and his heart sank, and he quickly hid behind the wall in the corner, holding a pistol in his right hand and the extremely sharp dagger that Section Chief Yu had given him in his left hand, staring at the stairs on the second floor. The sniper rifle was not good for close combat, he did not bring it down, and put it on the roof of the building.

As he listened intently, the faint voice became clearer and clearer, but he could not see anything in his field of vision.

For no reason, Niu Zhiyuan felt that something was constantly approaching him, this kind of strange thing was the first time he had encountered it, the unknown was frightening, this is human nature, so Niu Zhiyuan couldn't help but feel chills in his heart at this time.

Suddenly, Niu Zhiyuan's heart moved, and he put on the multi-functional glasses that the section chief gave him, and then he saw a figure wearing a gray tight leather coat and his face wrapped in a gray mask following him

The stairs move slowly upwards.

"Could it be that this garment has some stealth effect under the gray light?" Niu Zhiyuan gasped, some strange inventions designed by the Japanese people are famous all over the world, and they are indeed worthy of their reputation. And the person's movement is also extremely strange, as if the whole person is sliding on the stairs.

If you can't see that this is a figure, you think this is some kind of monster.

Suddenly, he saw the man in gray take out a disc the size of a baby's fist out of nowhere, and put it under the handrail of the staircase, and somehow fixed it there, this disc-shaped object was so small that if he didn't look down at it, he wouldn't have found it at all.

"This ...... This is a high-energy bomb. Niu Zhiyuan was horrified, looking at the appearance of the invisible man in gray, coming up from the first floor, it is estimated that a lot of high-energy miniature bombs have been installed.

Niu Zhiyuan forcibly suppressed the horror and murderous intent in his heart, held his breath, and waited for the gray-clothed invisible man to be about ten steps away from him, and suddenly dodged out of the hiding place, and shot the gray-clothed invisible man three times in succession.

Almost at the moment when Niu Zhiyuan shot, the gray-clothed invisible man lay on the stairs, and then like a snake, rolling left and right, moving up and down, the speed was chilling, at such a distance, with Niu Zhiyuan's marksmanship, the other party actually dodged three bullets in this weird way.

Niu Zhiyuan was taken aback, and immediately stopped shooting and stopped wasting bullets.

After a little observation, he decisively changed the way of shooting, and according to the law of the gray-clothed man's dodge, he instantly found the advance amount, and shot three times again.

"Poof", Niu Zhiyuan was overjoyed when he heard it, this was the sound of hitting the other party, but the speed of the gray-clothed man was not affected at all, and he still rolled and slid downstairs at an incredible speed, and the speed became faster and faster, like a puddle of sliding liquid.

"Could it be that this gray leather jacket still has the effect of bulletproofing?" Niu Zhiyuan had a realization in his heart, the pistol kept shooting again, and all the bullets were shot out in one go, he was sure that the man in gray was shot twice, but the speed of the man in gray was still unabated, and at this time he had even slid to the hall on the first floor, and was moving towards the door of the office building, but it was just possible

I was worried that the sound would be too loud and I would be discovered by the armed police at the door, so the speed slowed down a bit, and without the multi-functional glasses that Niu Zhiyuan was wearing, I couldn't see anything at all in this dark night without lights.

"Squadron Leader Luo, shoot at the door of the office building, hurry up immediately, don't ask me why." Niu Zhiyuan gave an order to Luo Lei through the headset, and at the same time, he did not advance but retreated, and rushed to the roof.

As soon as Luo Lei heard Niu Zhiyuan give the order in a stern tone that he had never seen before, although he didn't see any enemies at the door of the office building, he also heard the gunshots inside just now, so he didn't dare to slack off in the slightest, and immediately ordered his armed police soldiers to fire at the door of the office building.

"Da da...... " Countless automatic rifles fired, and immediately hit the man in gray who had just moved to the door of the office building, because there were more than 20 guns firing at the same time, forming a terrifying barrage, although the man in gray tried his best to dodge, but still hit a lot of bullets.

At this time, Luo Lei led the armed police soldiers to find that the bullets they fired seemed to hit something, one by one as if they had seen a ghost, and there was a look of fear on their faces, but the automatic rifle in their hands did not dare to relax, and they shot at the door of the office building like crazy, but after the gray-clothed invisible man was shot several times, the speed suddenly accelerated, and when the second round of shooting came, he had already slid to the side of the armed police blockade line, and drilled through the gap between the two armed police soldiers. Only a group of armed police soldiers were left shooting, and they kept shooting at the door of the office building like madmen.

Luo Lei first noticed that something was wrong, and immediately ordered to change direction and shoot in as many places as possible, but there was still no sound and phenomenon that obviously hit a physical object just now.

"The second and third squads turned around and shot backwards." Luo Lei's face suddenly changed, reacted, and gave a decisive order.

The armed police soldiers of the two squads quickly obeyed the order and turned around and opened fire from the back, but it was too late, and the gray-clothed man had already taken precautions, and after passing through the defensive line, he immediately changed direction and came to the side of the No. 2 office building.

Niu Zhiyuan rushed to the roof of the building, wearing multi-functional glasses and hurriedly looked down, the armed police soldiers in front of the office building kept shooting, but the gray-clothed invisible man had disappeared, he immediately looked into the distance, and still found nothing.
