Resisting a hard blow, shooting out, waving his wings, Yang Dongqing made a few moves in one go, and instantly killed the white yellow spring.

"It's so sharp!" cut the white yellow spring into more than a dozen pieces at once, and Yang Dongqing didn't expect it. He knew that the weapon worn by the mecha itself was very sharp, more powerful than a dagger, but he didn't expect it to be so sharp, it was estimated that it was a line higher than the seventh-level weapon of the Storm Gun, and he didn't even feel any resistance to this blow.

Thinking about the electric turn, Yang Dongqing didn't stop, with a wave of his hand, his spiritual power was released, and the chopped pieces of Huangquan were put into the space at once. This is all energy, of course, it can't be wasted, and now the space is short of energy. This time refining those essence blood, the functions of the hall on the first floor were closed.

As soon as he received the white yellow spring, Yang Dongqing did not run up the steps, but flapped his wings and flew up, the sound of the metal feathers rubbing was like flowing water, and a white streamer rushed straight up.

Now he can't continue to probe below, time is pressing, he needs to get back to Sin Star as soon as possible.

The wings flapped and rattled, and a circle of white air came out from behind the metal mecha, and the rumbling sonic boom that exceeded the speed of sound shook the stairs and corridors. It took him half an hour to come down, but it didn't even take five minutes to fly up.

Coming out of the stairwell, Yang Dongqing saw the huge transparent bottle at a glance, and the Huangquan essence blood inside was still full.

"It's strange, the liquid inside keeps dripping, why hasn't it decreased at all?" In the question, Yang Dongqing rushed to the huge glass bottle with a dodge and pressed one hand on it. Of course, he will not let go of this huge wealth, and he will not waste time by moving these into the space. As for the reason why Huangquan's essence blood would not decrease, he didn't think much about it at all.

"Huh~" The next moment, the entire bottle and the equipment above it disappeared without a trace. And Yang Dongqing paused for not even a second, and rushed out of the factory gate.

But at the moment when he left the factory, there was a loud bang, the space shook, and the factory collapsed suddenly, and the entire ground was sinking downward.

"Huh?" Yang Dongqing was stunned for a moment, and then he thought that this might be the reason why he took the huge bottle.

After a glance, Yang Dongqing didn't pay attention to it anymore, even if the entire space collapsed, it didn't matter, as long as he could open the closed metal door and leave

However, as soon as he raised his head and was about to return quickly, a large pale yellow color appeared in his sight.

"Four-winged Yellow Spring, so many?" Yang Dongqing was shocked, there wasn't a single Yellow Spring when he came in just now. And what made him wonder was that Huang Quan should have attacked Blackreef Fort, how could it appear in an enclosed space.

"Could it be the reason for killing Bai Huangquan?" Yang Dongqing turned his thoughts, stared ahead, took out the transparent liquid droplet and drank it. The attack power of the mecha is naturally speechless, but the physical strength and energy consumed are also huge, and in just a few minutes, his physical strength is almost exhausted.

Pouring the transparent droplets, Yang Dongqing shook the rainstorm gun, his wings flapped, and his body exploded forward, making a bang.

At this moment, a large area of four-winged yellow springs suddenly dispersed, occupying a larger area, no matter how Yang Dongqing flew, it was impossible to bypass it.

In the blink of an eye, Yang Dongqing rushed into the Yellow Spring Group. This time it was like pouring cold water into a hot oil pot, and the whole sky was in chaos.

The bright silver glow flickered in the air, puff puff...... A series of muffled sounds, and in just one shot, five four-winged Huang Quan were stabbed to death by spears.

"Wow~" Huang Quan's roar was also incessant, impacting the mecha from all directions. Yang Dongqing wanted to rush all the way over, but he didn't want to entangle with the other party. But the four-winged Huangquan was not afraid of death, and rushed over like a tide, wave after wave.

This was a complete slaughter, the strength of the mecha crushed the four wings of Huangquan for several streets, and a large number of Huangquan corpses fell from the sky...... However, there were too many Four-Winged Yellow Springs, Yang Dongqing finally had to slow down, even if he was anxious at the moment, there was no way but to kill the Four-Winged Yellow Springs as soon as possible, reduce their number, and when the density was not enough, he could get out.

This kill is half an hour, and the rainstorm gun is urging to kill souls, and each hit can kill more than three. But he was moving as fast as a turtle. Faced with such an overwhelming scene, he only understood the helplessness of those sixth-level masters guarding the city in the face of the four-winged Yellow Spring. In this half an hour, he consumed nearly ten drops of clear liquid.

Finally, there was a gap in the attack of the four-winged Yellow Spring, Yang Dongqing immediately increased his speed, his wings swung hard, and a silver light split a passage in the Yellow Spring, only then did he break out of the encirclement and accelerate towards the metal door, if he continued to entangle, it would really be too late.

The mecha definitely exceeded the speed of sound, but the speed of the four-winged Huangquan was not slow, and it was in hot pursuit in the rear. At this time, the ground around the wreckage of the ground spaceship turned upside down, and one by one the super huge yellow springs crawled out, looked up at the sky, and screamed at the mecha.

Yang Dongqing frowned, there are so many yellow springs in this closed space, obviously they are coming for themselves, and there should be no few on the metal door.

Thinking in his heart, the metal door was already in sight, just as he had judged before, a large yellow spring stood in front of the door.

Yang Dongqing squinted, drank a transparent droplet again, his wings contracted, and he fell from the sky to the ground, and then he erupted vigorously, and a wave of energy erupted from the feet of the mecha, using the starry streamer.

If he wants to open the gate, he must lower the height, and he will definitely be attacked by the four-winged Yellow Spring and the super large Yellow Spring, so it is better to fall down and face a kind of Yellow Spring directly.

The moment "Hum~" landed, the rainstorm gun in the mecha's hand trembled, and a streamer seemed to split the air. The gun was as fast as lightning, and the oversized Huang Quan in front of the door raised his claws to block it, but it could be blocked there, and there was a series of popping sounds, and Huang Quan was stabbed continuously.

"Get out of here!" Then Yang Dongqing shouted, the spear shook left and right, and the body of the spear actually made a sound like a bowstring.

"Papapa......" The oversized yellow spring in front of him was photographed by the body of the gun and flew out sideways. From the beginning to the end, he didn't even have a chance to fight back, which shows how fast Yang Dongqing's moves are now.

With one move, Yang Dongqing had already arrived in front of the metal door and shot out.

"Knock~" There was a muffled sound like a drum, and there was a noticeable fluctuation on the door.

"Energy protection, this door actually has energy protection!" Yang Dongqing exclaimed in his heart, and sent out without reservation. The mecha's right hand was raised, the spear was raised high, and it slammed down against the metal door, and a huge energy erupted from the body of the gun.

"Boom~" was like an explosion, the energy protection of the metal door shattered, and the body of the gun slammed on the door. The next moment, the metal door shattered.
