The two gardeners were quickly brought down with two shots – at this crucial moment, even knowing that these people were likely to be completely innocent, but still had to kill them for the sake of insurance.

"Something is wrong...... Everyone, be vigilant! ”

Cheng Yanqiu held the tactical flashlight in his left hand, held a pistol on his left wrist with his right hand, and rushed into the villa with swift and silent steps.

After Cheng Yanqiu rushed into the villa, the light source system in the villa immediately turned on the lights after sensing that someone had come in, and the originally dark villa instantly became brightly lit.

"Who?!"

As soon as the two fully armed guards ran down the stairs on the second floor, they were immediately knocked to the ground by a strafing shot, and after Cheng Yanqiu and the others killed the two guards, they each found cover in the house and aimed their guns at the staircase.

However, three minutes passed, and there was no movement...... It was as if only these two guards were left in the entire villa.

"That's not right...... Not right......"

Cheng Yanqiu's face was full of suspicion, no matter how much Cheng Su trusted the defense system of this villa, it was impossible to just bring such a little guard by his side, and if Cheng Su was in the villa at the moment, the alarm should have sounded the moment Cheng Yanqiu turned off the defense system, but now, there was still no movement.

"Here...... Could it be a trap? Thinking of this, Cheng Yanqiu instantly felt a chill down his spine - but even if it was a trap, they still ...... There's no turning back!

"Give me the shield! Rush up! Cheng Yanqiu took the bulletproof shield from the hand of an evolutionary, and rushed upstairs in the lead, and they followed closely behind Cheng Yanqiu with loaded firearms.

Restaurant on the second floor, no one.

The reception room on the second floor, there is no one.

The storage room at the end of the corridor on the second floor was also empty.

Then came the third floor, where the office, study, second bedroom, master bedroom – all empty.

Cheng Yanqiu searched all the way to the bathroom attached to the master bedroom, and kicked open the bathroom door, but in the luxuriously decorated bathroom, there was only a girl in a tulle costume squatting tremblingly in the corner.

"What about Cheng Su? Where are the others? ”

Cheng Yanqiu grabbed the girl's slender and white wrist, picked her up from the ground, and asked sharply.

"Home, head of the house...... The head of the family and the directors are out, out......" The girl's whole body trembled violently, and her frightened eyes kept sweeping over Cheng Yanqiu's guns, and she said with some slurred speech.

"Out? Where did it go? ”

"I ...... I don't know ......."

Just when Cheng Yanqiu was about to continue questioning, a violent explosion suddenly came from outside the villa, followed by the sound of firefighting between the two sides-

"Oops!" Cheng Yanqiu let out a low sigh, threw the girl on the ground, and rushed to the study on the third floor.

Behind the second bookshelf on the left side of the study is hidden the terminal of a villa's defense system.

Cheng Yanqiu immediately activated the villa's defense system again, and used the background authority to remove everyone except him from the whitelist of the defense system.

"The villa's defense system can buy us time for a while, but don't leave this house during this time, otherwise you will also be attacked by the defense system." Cheng Yanqiu said to the ghost face, at this moment, the people brought in by Cheng Yanqiu counted nineteen people including himself, and the remaining people who were guarding the courtyard had already been extinguished by the people outside with absolute superior firepower in the first round of firefighting.

"My dear nephew, I didn't expect you to arrive so soon, how is it, how does it feel to be home?" Cheng Su's voice came in from the outside of the villa through the loudspeaker, Cheng Yanqiu turned on the computer on the desk, and the monitoring screen showed that the entire villa had been surrounded by a large number of troops, but Cheng Su did not show up in person.

Knowing that Cheng Yanqiu had snipers under him, Cheng Su naturally would not appear in the other party's field of vision, but Cheng Yanqiu was sure that Cheng Su was definitely watching here at this moment when a surveillance camera could not see the screen.

"Yanqiu, I know, you must be in there—do you feel like you've stepped into a trap? Hahaha, it's a pity, it's unfortunate that I just had a meeting with the directors at Fort No. 1 on an improvised basis, but I didn't expect that as soon as I got home, I found a group of guests at home...... Oh no, we're a family, how can you be considered a guest? You're right, hahaha-"

The villa's defense system can block it for a while, but it can't stop it for a lifetime, if Cheng Su decides to attack the villa at any cost, it won't take him an hour, and he can sit on the position where Cheng Yanqiu is sitting now.

Cheng Yanqiu thought for a moment, then turned on the radio and said: "Cheng Su, since you have completely torn your face, then I don't bother to say anything more to you, if you want to get the ruins of Vault 909, then please feel free now." ”

"Ruins? What do you mean?! Cheng Su's voice immediately sounded, although the speed of speech was normal, but Cheng Yanqiu heard a trace of surprise in it.

"You shouldn't know yet, in order to deal with all kinds of situations that may occur, Vault 909 was built with a self-destruction system, and the control button of this self-destruction system is in this villa, so that when the Cheng family is in a desperate situation, they can have a chance to burn jade, as long as I press this button, the entire Vault 909 will be blown up in an instant, burying everyone alive here." Cheng Yanqiu said word by word.

"You...... You're lying, what a self-destruct system, it's all you made up, I've never heard of Vault 909's self-destruct system! Cheng Su shouted.

"I don't have to lie to you, this self-destruct system is only known to me and my father, if you don't believe it, you can try it - oh, by the way, if I'm not mistaken, you were in charge of the most oily cement and rebar procurement project when Vault 909 was built, right?"

"Yes...... That's right, Vault 909 was built when I saw it built, and there was no self-destruct system at all! You're empty, you're bluffing! Cheng Su said.

"Then you can check the original purchase bill, although this thing requires a lot of authority, but it shouldn't be a secret to you, you can find it, when the 909 Vault was built, there was a purchase order for 8,000 tons of TNT explosives, which was personally handled by my father, and the 8,000 tons of TNT explosives did not appear in the warehouse of the Cheng consortium, do you know where they went?"

Cheng Su was silent for more than ten minutes, and during this time, he obviously sent someone to verify the authenticity of the purchase order that Cheng Yan said in his words...... 8,000 tons of TNT is not a small amount, and the "little boy" who destroyed most of Hiroshima in World War II was only 150,000 tons of TNT equivalent.
