"After eating, don't forget what I told you! Let's go down first."

After successfully tricking He Meng, Yang Yu took Bai Jin to cross the deformed iron gate. He was not afraid that He Meng would not work after he had eaten. After all, He Meng still liked him very much, but he just felt upright and a little arrogant. After he had eaten, he would definitely work for him.

Following the winding stairs, spiral downwards. After a period of time, Yang Yu and his team arrived at a metal gate. There were many claw marks of steel dragon wolf on the door. For safety reasons, the Drug Research Office provided double insurance here.

The way to unlock the door is to put together a puzzle. Yang Yu put together the picture in three or five steps. Suddenly, the front suddenly became clear, the door opened wide, and the white light illuminated every corner here.

The Drug Research Institute is slightly smaller than the football field, and the workbenches of all sizes are arranged indiscriminately, but they do not feel messy. On the contrary, they are very simple.

There are various herbs and utensils on the workbench, and the air is filled with a faint fragrance of medicine. After careful observation, the tools for preparing medicines are not only common beakers and test tubes, but also many complex metal instruments, which have a faint smell of steampunk.

Since a long time ago, Yang Yu has felt that many RPG technologies in different worlds are fascinated by the technology. Although his cultural level is still in the Middle Ages, there are many things and settings that have only been found in modern times.

Even when Yang Yu's level is upper limit, the system actually gave him the option to build a machine.

Sure enough, is it common sense to be able to drive Gundam in another world...

Yang Yu only hopes that the devil who descends from the arrival system is not driving Gundam and bringing airplanes and cannons to attack the world, and it will definitely reduce the dimensionality and even fart.

I won’t mention whether the Demon King is flying a plane. Now, what makes Yang Yu most strange is that the Drug Research Institute is empty and there is not even an ant.

Where did people go?

Maybe they hid early when they heard the alarm, but they could not rule out the possibility of their rest after get off work.

It's impossible that I was scared to the point of hearing the explosion, so I went to take refuge together, right? That's too timid, right?

Obviously, Yang Yu was ready to catch several researchers and ask about the racial essence and the resurrection potion, but he had to do it himself.

"Bai Jin, I'll go from here, you'll go from there. You take what you can, I'll take what I can. Find the potion of resurrection, don't be polite, just drink it."

"I will look for what you said, too."

After looking at each other, Bai Jin and Yang Yu began to sweep the entire research institute separately.

The sweep speed is much faster than they imagined. It is not that they are faster, but because it is a research here, it looks very large, but there is actually not much to take.

Mature technologies have been put into production on the first floor or other places on the ground. Here, they are more trial and error and make better new drugs.

Of course, Yang Yu looked down on the semi-finished products and medicine residues that had too many negative effects or insufficient effects, and could only sweep away all the valuable herbs.

Finally, the two met in front of a workbench.

"How is it, have you found what you want?"

Bai Jin brought a bag of herbs to Yang Yu and shook his head, "No, have you found it?"

"It's a coincidence that I didn't find it either."

Yang Yu searched for a long time but couldn't find the racial essence he wanted.

"Can't we find the wrong place?" Bai Jin tightened his staff, his face pale. He clearly hoped was right in front of him, but he couldn't reach it. "Did all the previous efforts be wasted?"

The messy hair blocked Bai Jin's face, but it could not stop her swaying gaze.

"Don't give up in such a hurry." Yang Yu put his ear on the wall closest to the workbench and knocked it. "There is no finished product or sample here at all. In addition, no one is here. There are probably secret passages in this room that allow them to take shelter or store some more valuable things.

What exactly is self-evident.”

Yang Yu's words made Bai Jin regain the hope in her heart, and a ray of light ignited in her empty eyes.

"Tell me what I should do and how to find those secret passages."

Yang Yu frowned.

It’s not because he doesn’t know how to do it, but he knocked on the wall several times, and the sound he heard was no difference at all.

Just knocking on the wall in the movie can determine how thick the wall is. Can normal people really do it?

Resting against this smooth wall, Yang Yu couldn't help but fall into deep thought. The wall was cool and comfortable. Perhaps it would be nice to lean against the wall like this to make a salted fish.

"Walking in the secret passage, you naturally need a mechanism. Institutions are generally placed in places where ordinary people don't often touch them, such as a brick, a painting, or a book.

The way to turn on is also extremely simple. For example, toggling a switch, rotating a button at a certain angle, or pressing it directly. In short, it is generally not too complicated.

After all, if you run away, it will be embarrassing if you accidentally forget the method of opening the secret passage.

Most mechanisms will have certain traces after being turned on, and a few precision ones will return to their original state after being turned on. That kind of mechanism is also the most difficult to find."

"Did you mean that?"

Bai Jin gently pushed the smooth wall, revealing a red knob.

"Well, if you twist the switch like this, you will probably have a secret passage. Time is tight, so you can look for suspicious places as I just said, and then check them one by one. Nothing is a carpet-style search...it can't solve......"

When Bai Jin gently twisted the knob, the wall beside Yang Yu trembled. At the joint between the wall and the ground, a hole slowly expanded, moving Yang Yu's face upward, causing his voice to change shape.

Um?

Um--?

Um???!!!

Yang Yu tilted his head and showed a surprised expression that had not been revealed for a long time.

Damn—I found it so simple. Is there such a big difference in luck value of nine points?

Originally, Yang Yu thought it would take a long time, but in the blink of an eye, Bai Jin found the machine button lid that was not completely closed on the wall, and successfully opened the hidden space of the drug research institute.

The black wall beside him rose higher and higher, and a unique room gradually appeared in front of Yang Yu and Bai Jin.

The room was only the size of a classroom, with dark blue lights flickering, and various potions were placed in the glass cabinet at the innermost side of the room. However, at this moment, Yang Yu and Bai Jin's eyes did not stop in the glass cabinet filled with potions.

Pipes of all sizes on the ground are intertwined and inserted on a metal base, which carries a transparent glass cylinder filled with golden liquid, emitting a faint golden glow in the dim room, which is extremely conspicuous.

The transparent glass cylinder is sealed by a metal instrument, and a tube continues to inject traces of green liquid into it. The green liquids quickly merge with the golden liquid in the transparent glass cylinder.

And this is not something that really attracts Yang Yu. What really takes away Yang Yu's gaze is...

In the golden solution, there was actually a person sleeping in it.

That moment.
