Lu Yu was so busy watching the show in his spare time, but didn't stop it.

Bang Bang Bang, a few shots in a row, except for a few cracks in the glass jar, nothing happened.

The hardness of this glass jar is beyond imagination.

"Hehe, it seems that Mao Ziguo has nothing to gain."

Lu Yu smiled when he saw it, and motioned to Zhao Fei not to waste his efforts.

Bulletproof glass can be so strong that it is indeed rare in the world.

Unless you use a heavy machine gun to attack it all the time, it is impossible for the glass to be broken.

This technology is not so much self-developed by Maozi, but rather it is the technology they extracted from the alien spacecraft technology.

Although the alien spacecraft here is more complete, in terms of specifications, it does not seem to be as high-level as the alien spacecraft described in the fifth area data.

"I'm going! What glass? Why can't it break?"

Zhao Fei rubbed his eyes in surprise, as if not believing in evil, he approached and fired several shots.

But it's still itchy and it doesn't cause much harm!

"Okay, it can't run today, don't waste bullets here, let's quickly discuss how we can break through!"

Lu Yu reminded that the latter took the gun back unwillingly.

You don't have to guess, the outside must have been surrounded by the guards of the institute.

When the two want to go out, it is impossible to attack from the front. Basically, they have to become people to **** the souls of the dead.

The only possibility is to find a way from this huge internal space.

Lu Yu and Zhao Fei inspected each week, hoping to find a breakthrough.

Generally, in a large laboratory like this, there will be ventilation ducts leading to the outside world, which may be another matter if they cannot be found.

After looking for a long time, the effort paid off, and Lu Yu found out the location of the ventilation duct.

And by coincidence, it was just above the liquid glass jar.

To go up, you have to step on the glass jar.

but……

The five- or six-meter-high glass jar is straight like a pillar that supports the sky. It is extremely smooth and without any focus.

Nima's fly up?

When Lu Yu frowned and worried about it, Yu Guang caught a glimpse of Zhao Fei, throwing a small iron ball up and down.

Ok?

His eyes lit up and immediately thought of a good way.

Isn’t there a small iron ball? It just happens to be available!

Getting up and coming to Zhao Fei's side, Lu Yu snatched the small iron ball and placed it under the glass jar.

"What are you doing? That's my ball!"

Zhao Fei complained and wanted to take it back.

Lu Yu said angrily: "Do you still want to play? Right now, the surrounding water has long been blocked. Only the ventilation light above can let us escape! We can't climb up with our hands. Only this iron ball can help us. Go up."

What?

Zhao Fei didn't understand, but he didn't bother Lu Yu anymore.

Turning on the iron ball magnetic field, he was ready to jump up with the force of the rebound.

"Fuck!"

Zhao Fei slapped his forehead fiercely, grinning at the corners of his mouth to the back of his ears.

"Hehe, it's still your brains..."

"Stop talking nonsense, get ready to jump!"

Lu Yu stepped back two steps, approached forward, and jumped onto the force field.

Immediately, his body was bounced back vigorously, as if jumping on a trampoline, flying into the air.

Lu Yu felt like spreading his wings and soaring, but before he could understand it carefully, people had already bounced on the glass jar and hugged firmly.

drink!

As soon as he exerted his limbs, he easily jumped to the top and stood firmly.

"Come up." Lu Yu waved to Zhao Fei.

"okay!"

Zhao Fei learns everything, approaching, using the iron ball force field to rebound and jump.

However, there is a limit to the height at which the force field can fly a person, at about three meters, so there is at least a two-meter drop from the top of the glass jar.

"Wow ha ha ha ha ha! Fuck? Fun and fun!"

Zhao Fei bounced around in the force field just like this, playing very happy.

Lu Yu held his forehead and met a pig teammate, which was really troublesome.

He took off the two jackets, tied them together, and threw them down: "Stop playing, grab it."

Zhao Fei jumped forward and threw it high with the help of the force field, grabbing the sleeve of his jacket.

"Grasp it!"

With a soft drink, Lu Yu pulled him upward and Zhao Fei flew up and rushed to the top of the glass jar.

The two shook, holding each other steady.

Untied his clothes and put them on again, Lu Yu drew his dagger, removed the railing of the ventilation duct, and threw it on the ground.

Looking inward with the probe, Lu Yu supported the vent with both hands, and when he sprang up, he easily got into the vent duct.

Zhao Fei followed Lu Yu into the pipeline.

The line of sight in the ventilation duct is dim, but fortunately it is not narrow, enough for two people to walk side by side, and there is still a lot of space around.

"Go along the pipeline first and see where it leads?"

Lu Yu bowed his body and walked forward slowly groping.

The dust in the pipe was heavy, Zhao Fei covered his nose and muffled and said, "His grandmother, I didn't expect that one day I would actually have my turn to drill the pipe... These grandchildren, I will never let them go!"

Lu Yu squinted at him, and it seemed that the tasks this guy had done before were all relatively easy and real.

Regardless of how bulletproof vests can block ordinary bullets, if a PGD comes over, no bulletproof vests will work.

In order not to be bombarded into scum, the two can only avoid their sharp edges.

The pipes are full of all kinds of unpleasant smells, what kind of alcohol, the rancid smell of animal carcasses, and other strange smells mixed together.

If it weren't for the two of them being extraordinary and determined, they would have been smitten by this smell.

Seven or eight minutes later, they came to a vent.

"Shh!"

Lu Yu made a silent gesture.

Lie on the vent and look down.

Looking at the furnishings below, it seems to be an office, the environment is quite clean, surrounded by various experimental equipment and instruments.

Behind the desk, sitting a man in a white coat, was furiously reprimanding the people in front of him.

"Tank! Are you all a group of people eating dry food? I don't know that the institute was invaded. Do you want me to die again?"

The man slapped the table hard and roared: "The laboratory data is still inaccurate, and I take a big risk in doing this. If I fail, I don't have a second chance to resurrect!"

The few people in front of them were reprimanded just like grandsons, but they only dared not speak out.

This voice...

Lu Yu frowned, why did he always feel a little familiar?

His attention suddenly stopped on the words in the white coat.

resurrection? What the hell? !

Lu Yu adjusted his gaze. Due to the angle, he could not directly see the face in the white coat behind the desk.

"Return...return to Doctor, the guards have surrounded the spacecraft laboratory, they will never escape!"

Someone answered.

Hearing the words'Doctor', Lu Yu's heart suddenly froze.

Following that, an incredible thought arose...

As if to confirm his conjecture, the man called the doctor got up and walked out from behind the desk and stood in front of a few hands.

Ok?

Lu Yu flashed his eyes, took advantage of this opportunity to get close to the vent, and quickly cast down.

When he saw this person's face, Lu Yu was stiff as if struck by lightning.

"He, he is...?!!!"
