"Are you sure you want to use it now? There's still a wave of monsters coming! The doctor hesitated.

Chen Li nodded and said, "Use it now, otherwise I don't think it will last until then." ”

The number of contractors is still too small, and Chen Li knows that the space-time research center is also very rare for energy, otherwise there are at least hundreds of contractors in this one state.

"Help me get through Colonel Buxie, I'm Dr. Guderian."

The Doctor used the phone to call the operator on the military side.

"I'm Colonel Buxey!"

The doctor said, "Colonel, let's make a long story short, now, give us air support right away!" This is the Space-Time Energy Research Center, as long as you don't blow up into the building, blow it up! ”

He hung up the phone in a hurry, and did not give the colonel time to react.

A group of people are fighting monsters in the sky while waiting for fire support from the air.

After about half an hour of waiting, a special and striking engine hum sound came from the distant horizon.

The voice was full of power, roaring, roaring, almost tearing the black night in half.

Chen Li poked his head out of the cracks in the building, and under the frenzied aero engine, several sci-fi bombers flew above the monster group.

Dense small black dots immediately fell from the open belly under the plane.

Immediately after, a continuous burst of explosions completely surrounded the monster horde.

"Beautiful!"

Dr. Guderian snapped his fingers, and the erupting flames almost lit up the heavens and the earth, and the originally dark night became distinct, and the red and bright colors like the sun made it impossible to look at directly.

Charred corpses fell from the sky in flames, and a smell of burnt and gunpowder filled the building's surroundings.

This wave of bombardment passed, and the thousands of monsters above instantly decreased by more than half.

There is also a flying squad!

The bombing was divided into two batches of three bombers each, and the bombers erupting with blue flames came again.

Just as the bomber was about to open its belly and drop the bomb, a huge body suddenly attacked in the opposite direction in the midst of the monster group.

It stands to reason that although the technology of the ancient invasion of the world is not as advanced as the real world, the flight altitude of the bomber is at least more than 10,000 meters, but because it is necessary to avoid bombing the space-time energy research center, it has to reduce the flight altitude in order to attack more accurately.

Chen Li saw it clearly, and he felt a sigh in his heart.

The Anemo Pterodactyl took advantage of the air flow of the explosion below to attack from the opposite side of the bomber, and then in a staggered moment, it spit out thunderous sound waves, destroying the two bombers in just a moment.

"To die!"

A downed bomber happened to crash into the building closer to the building, and there were explosives inside!

Chen Li retracted his head, grabbed the two girls and threw herself to the ground.

A torrent of heat burst through the walls and swept into the building.

All the people who were standing in place just now were sent flying, and several contractors with relatively little blood exploded their heads into blood foam on the spot.

With a sound, the walls were unstoppable, the ears were heavy, and the seven-foot body was invincible.

Because of the explosives, the ground has now begun to shake terribly, and the power is several times stronger than the previous attack of the earthquake dragon.

As the blast of the explosion passed, a truly terrifying blazing flame struck the outer walls of the research building with thousands of degrees of flames, burning the concrete walls to black and peeling off pieces of rubble in a matter of seconds.

The flames burned past Chen Li's back, and with a light lick, it left a scar the size of a palm.

He was now about to be roasted, and he spat out a mouthful of blood, all steaming hot.

The heat wave rolled, the stone was like water, the iron was like mud, and it collapsed in an instant, and the red flame struck again, the flesh and blood withered, the white bones and embers, and there was no armor left in an instant.

When the fire slowly passed, Chen Li dared to raise his head in pain, and when he saw it, the walls of the one-meter-thick building collapsed, and there were few living people around.

Dr. Guderian's life is also great, and he will not die.

"Which bastard threw this! I'm going to Colonel Buxey to hang him! ”

Chen Li shook his head and went out to watch the situation.

About 500 meters away from the building, there was a huge deep crater with a drop of about 10 meters, and the overflowing water from the pipes kept filling the place.

The ruins of the surrounding buildings were basically swept away, and the height of more than one meter was gone.

He looked up at the sky again, and the bombers had already returned, and there were only a few hundred monsters left in the sky, and the rest had been reduced to powder in the explosion just now.

Wait a minute! And what about the Anemo pterosaur?

Chen Li searched around, but he couldn't find the shadow of this guy in the sky.

Didn't you get killed by the bombing?

He had some pain in his flesh, it was an orange item, and now it was the highest level thing in the Nightmare Space.

Finally, in the ruins next to the research center building, a lot of tile fragments suddenly crackled and fell, and Chen Li fixed his eyes to see that the Fengshen pterosaur with only half of its wings was dying there.

Did it!

Chen Li said to the two women: "Cover me and kill that Fengshen Pterodactyl!" ”

The three of them jumped out of the building that was almost indistinguishable from the ruins, and hurried towards the location of the Aeolian Pterodactyl.

Galloping all the way, the Aeolian Pterodactyl also knew that it was at the end of its rope, and no longer struggled to continue to fly, but opened its mouth, and with a strange scream, the last few hundred remaining flying creatures in the sky swooped down.

It's black again, the two sides have been fighting for so long, since the early hours of the morning, and now it has been more than two hours, and the sky is slightly lit up with a halo.

Chen Li took advantage of this brilliance to punch the monster above his head, and the monster in a straight line was immediately crushed into pulp.

These monsters didn't have much blood originally, and they had also experienced bombardment, and at this time, they were hit by his soul fist, and they dissipated in the air in an instant.

"It's useless!"

Although the explosion just now also affected Chen Li, but as an authentic MT, his blood volume has long exceeded 2,500 points, and the blood recovery speed is more than 30 per second, and he is scorched by the flames across the wall, but there are only a few minor injuries, and the two girls are protected by Chen Li, and they also have guardian skills, so it is not a big problem.

With a single punch, these last monsters scattered around the three of them, and launched a desperate attack.

Although the damage is only a few points each time, the frequency of such a dense attack is also quite terrifying, and every second, Chen Li has to withstand the attacks of dozens of monsters.

Zhang Xiaoxin in the rear pulled out an ice arrow, shot it with a bow, and froze several monsters with one arrow, Luo Yun also danced the moon blade, cutting vegetables back and forth in the middle of the monster group.

The three of them fought to the death in this ruin.
