When Ling Fei used the flashlight to look over, the ninjas had already left. They indeed had an advantage in the darkness and could be said to have come and gone without a trace.
At the same time, several ninjas had passed through the slings and arrived at the top floor of the research institute, ready to break in.
Not only that, there were seven or eight others who entered through the window. They did not choose to attack all at once but were divided into three teams.
A group of security personnel gathered in front of the door of the research room. The two rows just now used flashlights to shine on the corridor in front, and at the same time, the stun guns in their hands were ready to fire at any time.
"Everyone must be careful," the security captain said.
Now they have learned who their opponent is, a ninja who comes and goes without a trace, so they must maintain a high degree of concentration.
Time passed by second by second, and it was a lie that they were not nervous. After all, no one would have guessed that their opponent would be the legendary ninja.
The corridor in front of them was very dark. I don't know if it was because they were dazzled or something else, but they seemed to see dark shadows moving quickly in their eyes.
But the flashlight that shined through it didn't reveal anything unusual.
The security captain squinted his eyes tightly and slowly raised his hand.
Just when everyone was nervous, a ninja could be seen appearing in the flashlight range.
"shot!"
The security captain waved his hand, and all the security personnel immediately opened fire, but ninjas are ninjas and can fly over walls and walk on flat ground.
A jump means moving quickly on the ceiling. Fortunately, there are security personnel in the second row who can shoot.
The effective range of the stun gun is within five meters, although if the ninja is hit, it will cause paralysis for a long time.
Sizzle...
As the electric gun was fired, several ninjas were hit and stimulated by the released electric current.
The ninja fell to the ground and kept twitching, but he had other companions. When the three ninjas approached, the poison darts in their hands flew out immediately.
"careful!"
The security guard standing in the second row immediately took out his blocking shield and stood in front of everyone.
Because the opponent is a ninja, they must be prepared to defend with darts, and the shield can be used at this time.
Dang Dang Dang!!!
The darts hitting the shield had no effect. Instead, the two ninjas were hit by the stun guns.
The strong current made them shake like sieves and fall to the ground weakly.
Because the electric gun can only be fired once, everyone can only change the gun in time. They only need to hold on. As for the life and death of the ninja, they are not in charge of it.
A total of five ninjas fell in front of them, and the security captain let out a breath.
Fortunately, he listened to Ning Fan's advice and made special preparations, otherwise they would have died under the ninja's darts.
"Don't take it lightly."
"yes!"
The ninjas at the back also found that it was difficult for them to break through this defense. The ninjas who also sneaked in from the top floor were blocked by the security personnel.
They won't be able to come down to support them for a while. It seems that this mission will be difficult to complete in one go.
But they only have this chance. They must get all the information about the serum tonight.
"It's time for you two to take action."
Two ninjas came out, they took out their samurai swords in unison, and walked step by step towards the security guards' defense.
"Everyone, be careful." The security personnel were on standby.
Woohoo!!!
These two ninjas were obviously much stronger than the previous ones. They moved very fast, and the darts in their hands had already arrived in front of the security personnel.
The security personnel immediately lowered their heads and hid behind their shields, then immediately stood up and started shooting.
