Yang Dongqing finally knew why he had come to open the fortress with so many white yellow springs, because these dots on the virtual screen had to be hit at the same time. In the range of 100 square meters, if you want to hit these dots at the same time, let alone one or two people, three or five may not be able to do it at the same time.

But others can't do it, but Yang Dongqing can, his big silk can send out multiple forces at the same time, as long as it is controlled, hitting these dots at the same time is not a problem at all.

With a flick of both hands, hundreds of strands of energy flew out from between the mecha's fingers and hit the dots.

"Huh~" The dots lit up, and then the line segments connected these dots together, and Yang Dongqing was surprised to find that the originally chaotic dots were actually a wolf's pattern.

Then colors appeared on the holographic screen, and an unusually handsome giant wolf gradually took shape. Dressed in long cyan hair, with a tail mopping the ground, looking up at the sky, as if howling at the moon.

"Boom~" Yang Dongqing, who was looking at the giant wolf in a trance, suddenly felt a shock under his feet, and suddenly came back to his senses and found that the hall was jolting up and down.

"The base is open!" Yang Dongqing said secretly, turned around and ran out the door. Although the base is open, the operation has to go to the control center on the upper level, and the base must come out of the underground before he can put it into space. Otherwise, even if he emptied the energy of the space, he would not be able to bring into the space the base buried in the ground with a diameter of thirty kilometers.

The bump continued, and at the same time as Yang Dongqing flew out of the gate, the stabbing ball rolled out of Yemen.

When I came, it was all the way uphill, and now it's all the way downhill, Yang Dongqing is flying in front, and the thorn ball behind is also rolling rapidly. However, Yang Dongqing didn't have the heart to pay attention to the situation behind him, the entire passage was shaking violently, and rocks were constantly falling, and he was worried that this passage would collapse.

"We have to hurry to the fork, it should be the edge of the fortress!" Yang Dongqing thought to himself, took out a bottle of transparent liquid droplets and drank it, controlling his wings to flapp quickly.

Seeing that the fork was getting closer and closer, just as he was about to turn the corner, the passage ahead of him twisted. Then the wall collapsed, and a pitch-black hole appeared in Yang Dongqing's front. Behind him and on both sides, the entire passage collapsed.

Yang Dongqing saw that the surroundings were collapsing, and he had no choice but to fly into the cave that collapsed. Immediately following him, the thorn ball rolled in.

After plunging headlong into it, Yang Dongqing's vision was pitch black, and he could only hear the constant roaring sound behind him.

Flying forward for a while, his vision gradually adjusted, it was not dark here, there was some faint light. Looking around, he found that this was an even larger underground space, except for the cliff behind him, there was no end in sight to the left, right and front.

The roar behind him continued, and Yang Dongqing could feel that the space seemed to be shaking as well. He stopped, standing still in the air, unsure of which way out he was going, and he wanted to wait for the collapse to stop.

After a while, the roar finally quieted down, and then faded away. Yang Dongqing immediately turned around and flew back.

When he returned, he found that the place where he had come out was a huge stone wall, with no end in sight. And that hole has long been blocked by the collapsed passage.

"It's almost impossible to dig out, and a lot of the passage has collapsed. Yang Dongqing showed a hint of anxiety, he was now trapped here.

"How can opening the fortress still cause the underground to collapse, and it is not officially operational. Yang Dongqing was a little depressed, this was a completely unexpected change.

Taking a deep breath, Yang Dongqing forced himself to calm down, it was useless to be anxious now, he had to find a way out first.

After thinking about it, he waved his wings and flew up, first he had to find out the situation of this underground space. He estimated and calculated, and flew about 5,000 meters and touched the rock.

Then he flew down again, returned to the collapsed entrance, and flew down more than 3,000 meters, landing his feet on the ground.

"This underground space is more than 8,000 meters high, which is really not small. Yang Dongqing said secretly in his heart, waved his wings and flew up, and flew forward against the ground.

"Huh?" Flying forward for more than three hundred meters, Yang Dongqing suddenly saw the thorn ball in the rocks.

"This guy has fallen too!" He didn't even look behind him when the passage collapsed, so he didn't pay attention to the stabbing ball.

Yang Dongqing thought about it, prepared to ignore it, and continued to fly forward to find a way out. This thing is too powerful, he doesn't dare to throw it into the space, even if the root system can handle it, who knows how much energy it will consume, and if it collapses again, he will collapse.

I made up my mind to pay attention, and Yang Dongqing was about to fly over to it. But just as he was about to make a detour, the thorn ball suddenly clicked softly.

Yang Dongqing was startled, and hurriedly flew out more than thirty meters upside down, keeping watch and being vigilant, if the black lava came out again, he would not fight hard.

"Click...... The sound of trees cracking constantly sounded, and it looked eerie in the silent underground world.

Yang Dongqing stared at the thorn ball, motionless, and his body was still slowly retreating.

After about three minutes, the clicking sound suddenly stopped, and the whole spike ball split into four petals.

Yang Dongqing was startled, and his figure immediately pulled up and jumped up more than two hundred meters.

Looking down from the sky, it was not clear in such light, but Yang Dongqing could still see that there was no black lava flowing out of the thorn ball.

"No?" Yang Dongqing thought for a moment, and slowly approached downward, and the qi energy circulated rapidly in the qi veins.

The line of sight gradually became clear, and Yang Dongqing found that there was indeed no black lava, and the thorn ball was like a durian that had been cut and the flesh had been dug out, evenly divided into four petals.

"What's the situation?" Yang Dongqing flew closer and closer, and finally landed next to the cracked thorn ball.

"If you fall from a height of three thousand meters, you won't fall to your death, right?" Yang Dongqing said secretly, and then shook his head again, this guy was smashed by all his strength and was not damaged at all, how could he fall to his death, this is an interstellar plant.

Reaching out and touching it slightly, the thorn ball was left with a shell. It feels like being sucked out by the roots of space.

"Really dead?" Yang Dongqing was extremely surprised, where did all the black lava go. After eating so many star-level weapons and a rainstorm gun, why is it gone?

As soon as he thought of the rainstorm gun, Yang Dongqing couldn't help but feel pain, and when he threw this weapon, he was equivalent to losing his right arm.

After turning around the thorn ball, Yang Dongqing suddenly found that there seemed to be something at the bottom of the cracked thorn ball.

He immediately squatted down and leaned over, and then there was surprise in his eyes, it was actually three seeds, the size of a thumb, full of spikes, exactly the same as the seed that Tianya had given him back then.

"I see, it was cultivating and breeding offspring before, I said why is the black lava gone, it turned out to be transformed into energy and turned into seeds!" Yang Dongqing said, reaching out and pinching the three seeds.
