Just as Xu Tian had just entered Lop Nur, near the research institute, a huge eye was suspended in the air, looking coldly at the desert below, beside it, three demons stood quietly, for a long time, that eye made a dull voice: "I have raised your level to the middle of the four-star stage, no one on the entire earth is your opponent, if you fail again, you don't have to come back alive." ”

The three demons did not speak, but quietly looked at the research institute in the distance, and the eye snorted, "Hmph! I'll go first, good luck to you." ”

With that, a circle of ripples appeared on that eye, and after a second, it disappeared into the ripples.

One of the three demons said, "What is the origin of this guy, and why did he order us?"

Another said: "I'm afraid no one knows its origin, I only know that the three great earth kings have to give it face, and we can only listen to it." ”

The third person said: "It can actually raise our level at will, this ability is really terrifying, I don't know what level it is?" Forget it, let's start acting, otherwise it will make that guy unhappy, and it will be easy to kill us." ”

Professor Zhou Kai sent Wang Feng into the laboratory, and he was observing the situation in the laboratory through the big screen, at this time Wang Feng had fallen into a coma, he was lying on the bed, the metal part of his body had been opened, revealing the flesh and blood and various mechanical mixtures inside.

Wang Feng's muscles are knotted, he looks very strong, I am afraid that there are not a few such people in the world, the conditions for becoming an adjuster are very harsh, this has nothing to do with high technology, and the requirements for physical fitness are very high if you want to become a high-level adjuster, which is why there are so few adjusters, if there is no good physical fitness, no matter how clever scientific and technological means can not transform it.

Zhou Kai has undergone strict screening, and there is only one person who is suitable for using photon force technology, and whether he can succeed depends on Wang Feng's will, this experiment is also crucial, if it fails, then this technology cannot be used on earthlings, because it is difficult to find someone with better physical fitness than Wang Feng, if it succeeds, then there will be an invincible warrior on the earth.

Just when Professor Zhou Kai was intently looking at the screen, the alarm suddenly sounded, and Bing's anxious report came from the communicator: "Professor, the demons are here, there are three people in total, and after scanning, it is confirmed that they are all four-star demons in the middle stage." ”

Zhou Kai's brows furrowed, three four-star mid-stage demons, such a lineup may not be able to stop a large number of troops coming, after thinking for a while, Zhou Kai said to the communicator: "All the soldiers in the base are dispatched, all the weapons in the base are fully opened, there is no need to defeat the enemy, as long as the time is delayed, we have two chances, one is the arrival of reinforcements from the central government, and the other is that Wang Feng's experiment is successful, as long as we hold on until that time, we will win." ”

"It's the professor, my subordinates understand. The soldier ended the communication, and then conveyed Zhou Kai's order downward.

The three demons came to the sky above the research institute, flapping their wings and spitting out lightning bolts from their mouths to attack the research institute.

A group of soldiers walked out of the research institute, and the soldiers standing at the front opened their protective shields to intercept the lightning emitted by the demons, and at the same time covered the soldiers behind them, while the soldiers behind began to shoot with various weapons.

At the same time, countless fighters rose into the air and surrounded the three demons, and bullets rained down from the demons' bodies, and the three grinders had electric currents constantly flashing, blocking the bullets that were fired.

A golden light lit up around the research institute, and the golden light shrouded the research institute like an umbrella, which was a photon power shield, and it would take a lot of trouble to break it.

At first, the three demons didn't pay attention to the army of the earthlings, they just released lightning at random, thinking that they could easily destroy the research institute.

But after a long time, the research institute was still intact, but the lightning protective film on their own bodies was about to be broken, and the three of them began to get serious.

"I'm going to get rid of the flies in the air, and you're going to continue to attack the Institute. ”

As one of the demons spoke, he flew towards the group of fighters, spitting out a jungle of lightning from his mouth, killing more than a dozen fighters in an instant.

The commander of the fighter group said into the communicator: "All the units are scattered, we just need to delay the time, there is no need to die." ”

Under the flexible command of the commander, the fighter group played guerrilla warfare with the demon and successfully trapped him in a circle.

The other two demons also began to split up, one continuing to attack the institute and the other to deal with the ground forces.

Although the number of ground troops is not too much, they all use photon power shields, and at first they also tried to attack the demons, but the strength of the opponent's mid-four-star is not fake, and in the end they can only give up and use all their energy on defense, anyway, as long as they can drag the other party, it will be fine.

And the grinding man who attacked the research institute was not comfortable, no matter how powerful the lightning he unleashed, it would be bounced back when it hit the photon power shield, and a few times it even hit his own body, and he was attacked by his own lightning, which was not very good.

However, this demon also discovered that as he continued to attack, the photon power shield was also weakening, and as long as the energy was exhausted, the shield would disappear, so this demon continued to attack, while dodging the lightning that rebounded back, and played a war of attrition.

Time passed minute by minute, Professor Zhou Kai's heart also hung up, the reinforcements from the central government were delayed, Wang Feng's body transformation had not been completed, he was still in a deep coma, and he didn't know if the army and protective shield outside could hold on, and now he could only expect a miracle.

The two sides were deadlocked for half an hour, and the military of the research institute was already a little unable to support it, and the fighter brigade in the air withdrew first, there was no way, the fuel of the plane ran out, but the abrasive magic power did not diminish at all, as if he didn't know that he was tired at all, and he was still secretly refreshed in his heart: "The middle of the four-star is really extraordinary, even if I fight until the end of the world, I won't be tired!"

The ground forces are no longer good, and their photon power energy is also exhausted, but as soldiers, they refuse to retreat, and still shoot into the sky with their weapons, but the death toll is rapidly increasing with the attack of the demons.

And the research institute's photon power shield energy is also not much left, the golden protective shield has turned into a translucent color, which is a sign that the energy is about to run out, the demon saw the color of the protective shield, his eyes lit up, and the frequency and power of the attack increased.

Zhou Kai sighed and said in his heart: "It's over, it's over, my experiment, the future of mankind, hey!"

At this moment, three figures approached rapidly from the far distance of the desert, their speed was so fast that even the radar of the research institute could not detect it, and by the time the radar found it, they had already arrived at the battlefield.

The soldier in charge of monitoring the radar reported to Zhou Kai: "Professor, we have found three unidentified people, two people and one dog to be exact, they have arrived at the battlefield, but we can't confirm their identities. ”

"Contact the other party and ask who they are?" Zhou said.

"There was no way to get in touch with each other, and they didn't seem to be carrying communication devices. ”

Zhou Kai thought for a while and said: "Observe first, if they are their own people, fully cooperate with their actions, if they are enemies, activate the self-detonation device of the research institute, even if they are dead, I will take them to the funeral." ”

"Professor, don't be rash, there will be another way. ”

Zhou Kai showed a resolute expression: "At this point, there is no other way, once the self-reporting system is activated, you can leave." ”

"What about you, Professor?"

"Everything I have is in this laboratory, it's gone, and there's no difference between me living and dying. After speaking, Zhou Kai ended the call and no longer gave the soldiers a chance to persuade him.

The three figures who came to the battlefield were Xu Tian, Yuan Ziye and Xiaobai, and they saw the situation on the battlefield from afar, so the two of them and a dog quickened their pace and rushed over.

Before they got close to the battlefield, Xu Tian and Yuan Ziye saw that the level of the three demons was not low, and Yuan Ziye asked, "Brother Tian, what level do you say they are? Could it be the three-star stage? Looking at their combat strength, they should be worthy of this level." ”

Xu Tian smiled and said: "It seems that your actual combat experience is still too little, those three people obviously did not use their full strength, if they play with all their strength, they can definitely scare you, I guess they are all four-star mid-stage." ”

Yuan Ziye's cherry mouth opened widely: "Three masters in the middle of the four-star stage, how is this possible, there are not many such people in the entire earth, how can a demon send three at once?"

Xu Tian showed a bitter smile: "I don't know, I only know that we probably won't have a good life in the future." ”

The three intermediate-level Meteor Venerable level opponents, even if Xu Tian is against him, I am afraid that he will only be beaten, Xu Tian began to rejoice, fortunately he brought Yuan Ziye and Xiaobai, otherwise he would be really in trouble.

Yuan Ziye said: "Why doesn't the research institute prepare more defensive measures?"

Xu Tiandao: "The defense of the research institute must be very sufficient, but no one would have thought that they would meet so many demon masters, and in the face of three such masters, it is useless to have many troops, so Chen Qiao will think of me." ”

They ran as they talked, and soon came to the center of the battlefield, Xu Tian shouted to the soldiers who were stubbornly resisting: "I am Xu Tian, leave the rest to me, you can rest first." ”

Hearing the name Xu Tian, the emotions of all the soldiers suddenly rose high, there must be those who have not seen Xu Tian, but those who have not heard Xu Tian's name must not, he is the first person on the earth, and his girlfriend is the first person on the earth to succeed him, such a reputation, if someone has not heard of it, then he can clean up and die.
