Yang Yi flew to the left flank and ran seven or eight hundred meters to an open area without trees, and the helicopter was less than a kilometer away from him.

Without the slightest hesitation, Yang Yifei bought nine large pieces of steel of one cubic meter from the system mall, although the steel of the Qing Dynasty could not be compared with modern times, but the thickness of one meter was not something that a 20 mm cannon could shoot through.

These steels are 1 point and 1 cube, and Yang Yifei only spent 9 points to build a solid bunker with a shooting hole in front of him.

There were four blocks on the ground side by side, three of which were spaced apart, leaving a shooting hole 1 meter high and 50 centimeters wide on the left and right, and the remaining two pieces were placed on top of the shooting hole, and a bunker stronger than any pillbox was formed.

Immediately, Yang Yifei took off Barrett from behind, knelt on one knee, put the gun in the shooting hole in a kneeling shooting position, and quickly put on the first helicopter on the left wing with the crosshairs.

Distance, 612 meters, wind speed, 1.6 miles per hour, wind direction, southeast to northwest......

Very good, this wind speed is no different from no wind, Yang Yifei did not fire rashly, and waited for the helicopter to fly 500 meters, and then slowly pulled the trigger.

"Bang"

"Boom"

This shot hit the fuel tank, and after the high-explosive bomb penetrated the shell, the spark of the explosion detonated the fuel, and after firing this shot, Yang Yifei decisively withdrew Barrett, and the whole person lay down.

Sure enough, the next moment the guns of the other helicopters spun around.

"Aggressive ......"

"Jingle ......"

A dense crisp sound suddenly sounded on the outside of the bunker, sparks flew everywhere, and countless bullet holes the size of a dense fist instantly appeared on the large steel block, but this bullet hole was only large, but it did not penetrate much.

But the kinetic energy of the bullet pushed the steel block located above outward little by little, Yang Yifei saw this, and decisively bought nine more steel blocks, rolled it a little distance inside, and stacked another layer inside, so that the cannon bullet could no longer push the steel block above.

Yang Yifei was lying behind the bunker with the gun Shi Shiran, and he was not afraid that the other party would come around, so it was a big deal to build another bunker on the other side.

After a brief pause in the helicopter, he immediately rebounded and mounted Barrett.

This time he fought more easily, because the helicopter was already close to 200 meters away from him, and almost only fired directly after the slightest aim, and even the pilot did not react.

Even if the other party reacts, it is useless, even if the cannon button is pressed immediately, the cannon has a two-second pre-rotation time, and the bullet will shoot out after two seconds, Yang Yifei seized this time difference and easily killed the second helicopter.

"Boom"

Another helicopter was reimbursed, but this time after Yang Yi retracted back, the helicopters did not fire again, but pulled up and turned around one after another and flew back.

Yang Yifei took a look at it, Nima, this situation is not in vain! Just as he set up his sniper rifle and was about to take down another helicopter, a sound sounded from the tablet in his pocket.

"A kung fu master from Huaxia, you deliberately opened the hot spot to talk to me, right? I'm giving you this opportunity now. ”

"Whew"

Exhaled, Yang Yifei reluctantly put down Barrett, and took out the tablet from his pocket, at this time the tablet was in a state of video call, and the face on the screen, who was it not Isaacs?

"Hello, Ambrera executives, what shall I call you?" Although he knew who the other party was, he understood that he "shouldn't" know.

The more he shows that he knows, the more the other party will not let him go easily, and when it is time to pretend to be stupid, Yang Yifei will never be brainless and strong, and increase the other party's attention to himself for no reason.

Isaacs clearly had no intention of reporting himself, "You can call me Doctor." ”

"Okay doctor, I suppose you've sent an army against us with great fanfare, right?" Yang Yifei said as he took out the test tube containing Alice's body fluids from the storage space and shook it in front of the camera.

Isaacs' eyes narrowed slightly, and he said, "What is this?" ”

Yang Yifei said: "Alice's genes. ”

Isaacs stared at him and said, "What do you know?" ”

Yang Yifei smiled and said: "Alice has told me everything she has experienced and everything she knows, and through some analysis by myself, I have come to the conclusion that Alice ...... It must be the biochemical warriors you made, right? ”

Isaacs's heart was relieved, it turned out to be just like this, but his face was silent, but he said with a gloomy face: "You are very smart, but sometimes it is not a good thing to be too smart." ”

Yang Yifei's face also sank, if you want to play, I will accompany you to race, "I will also tell you that I was just an ordinary person who didn't know anything, liked cospy, and liked kung fu." ”

"It's all this that you brought out, dragging me into a crisis, I just want to live well, and I choose to resist in order to protect myself."

"If you want to get Alice's genes and continue your research, I can fulfill you, but the condition is, don't provoke us again, otherwise, I will let you know the consequences of provoking a Chinese ancient martial arts inheritor."

Looking at Yang Yifei, who looked more and more angry, Isaacs's mood became more and more relaxed, his eyes flashed slightly, and he smiled: "I'm sorry for the trouble caused to you, I don't know if you are interested in cooperating with me?" Your ancient martial arts are valuable for research. ”

"If you are willing to cooperate with me, I can make you a senior of Ambrera, and you will gain unimaginable wealth and status."

Yang Yifei said mockingly: "Don't think about this, I don't have a hobby for people to study, not to mention, although Huaxia's technology is not as good as the United States, it is not much worse." ”

"If the ancient Chinese martial arts are something that can be analyzed scientifically, the world hegemon will not be the United States, but Huaxia, and it will be your turn to play the prestige of your biochemical warriors?"

Isaacs suddenly said, it is true, the ancient martial arts of Huaxia are originally more idealistic things, at least with the current technology, it cannot be analyzed, otherwise with the ability shown by Yang Yifei, as he said, Huaxia would have dominated the world a long time ago.

Isaacs said: "Even so, I still hope to cooperate with you, you know the practice method of ancient Chinese martial arts, which is already very valuable in itself." ”

The irony on Yang Yifei's face was even stronger, and he said: "If you want to learn ancient Chinese martial arts, you must first have an in-depth understanding of Chinese culture, especially Taoist culture. ”

"After understanding all this, it will take more than ten or twenty years of uninterrupted practice to see results, you foreigners don't have to think about it, even if it is taught to you, you can't learn it."

This is naturally Yang Yifei's excuse, it is undeniable that what he said makes sense, some advanced exercises do require the conditions he said, but the external kung fu of Mixed Yuan Zhang is not among them, as long as he is willing to teach, he can basically learn it.

After all, this exercise is already a modern thing, and there is no esoteric reason, it is just that the external exercises are combined with a specific breathing and breathing method, and the most glorious time of Chinese martial arts is the martial arts world of the Middle Ages.

Yang Yifei didn't trust Isaacs at all, he knew very well that he just wanted to use himself, if he really taught martial arts to the other party, the first thing the other party would do after practicing was to kill himself.

Do you have to be a brainless person to do this kind of thing that teaches your opponent the hole cards that you can endure to survive?
