Siheyuan: Forgive me!I Xu Damao is willing to support the whole hospital

Chapter 168

Suddenly, he touched a deep groove in the wall.

Xu Damao was pleasantly surprised, he stroked nearby, and at the bottom right of this groove, he touched another groove!Immediately afterwards, he reached down with his hand and drilled into the platform made of chairs on the next floor. Sure enough, there was also a groove at the lower left of it.

No wonder I didn't touch the ladder. It turned out to be a groove like a climbing rock, and it was set high and out of reach!

In order to prevent being touched, the lowest level of the climbing slot is also deliberately set within the reach of one's own arms.Even if you hold your breath and feel around the room, you can't find anything!

This shows from the side that people who use the climbing trough should be quite agile and can jump from a height of 2 meters without difficulty.

Xu Damao was overjoyed, stepped on the climbing trough with one foot, and put his right hand on the hole above, and was about to continue climbing up. The hole leading to the ceiling mezzanine must be right above!

However, Xu Damao suddenly felt dizzy, as if he was about to collapse.

what happened!No, the other party has increased the dose of paralyzing gas!I can't even metabolize this reply speed!
At some point in the air, a thicker smell began to fill the air!
Xu Damao hastily closed his eyes. He had an [-]% recovery rate per hour, but he didn't know how effective the restoration of his eyes would be.

"No, seal the hole!" Xu Damao shouted down at the risk of inhaling too much paralyzing gas.

"Are you okay?" Hu Bayi rushed over when he heard the shout.

"Don't worry, it doesn't matter to me, you all listen to the movement on the ceiling!" Xu Damao said.

In a critical moment, Xu Damao used his 3D printing skills to bring back a goggle with 300 spiritual power and a gas mask to wear on his face.

Your uncle, you want to use dirty tricks, right? You made the wrong idea, and I will fight you to the death today!

Xu Damao put on goggles in the fog,

Fortunately, it is winter now, Xu Damao was wearing a green coat with electrician's gloves in his pocket, and now he hastily put it on, but he was well protected.

The sudden appearance of the paralyzing gas made Xu Damao calm down and think.

For this inexplicable fog that lingers no matter what, he was filled with awe from the bottom of his heart. Subconsciously, he had already determined that something supernatural was causing the trouble, and he didn't want to be too offensive and forced to create the reason for this fog.

But looking at it now, the composition of the fog can change. Obviously, it doesn't look like the work of some monster. On the contrary, it is certain that the other party has used some science and technology to play tricks!

Xu Damao activated his paparazzi skills, his eyes were burning, and under his infrared and ultraviolet vision, he quickly discovered that there seemed to be five or six circular areas at a height of 2 meters above his head, and the temperature was lower than other smallpox.

This can only be seen by standing at a height of 4 meters. Even if I turned on the infrared vision on the ground, I couldn't find it.

Xu Damao withdrew a few chairs from the lower floor, set up a higher ladder under those circular areas, and finally reached the ceiling there.

The temperature here is the lowest and the fog is the heaviest. It is several times heavier than other places, and you can't see anything at all, but Xu Damao knows it is a hollowed-out manhole cover by the feel of his hand!
I understand, these circular areas are likely to be several air outlets!These lingering fogs are emanating from there!

These air supply outlets are just like the air supply outlets of centralized air conditioners in shopping malls and offices!
With Xu Damao's strength, the manhole cover of the air outlet was removed, and hundreds of ice cubes fell from it like hail.

The ice cubes turned into gas, and the fog became thicker.Xu Damao picked it up and saw that the temperature was slightly higher than ice.

I know, it turns out it's dry ice!
Dry ice is solid carbon dioxide, which will slowly turn into gas at room temperature. The smoky scenes in film and television dramas are made of it!

The tuyere was still sending out another gas, and Xu Damao almost fainted when he encountered this gas!

Damn, this is the source of the paralyzing substance!
Xu Damao climbed towards the inside of the wind tunnel against the violent paralyzing gas. The diameter of this thick wind tunnel was more than 1 meter, and it quickly turned horizontally.

After climbing for a short time, I suddenly felt a circular iron plate sealing the flue, probably a flange for changing the diameter between the thin air duct and the wide air duct.

On the other side of the flange is an air duct with a diameter of less than half a meter.

Can't climb over.

But Xu Damao was not in a hurry, he couldn't stop hitting the air duct with his right hand, because the iron air duct had long been corroded by the gas, it was already vulnerable at this moment, and it would be penetrated soon.

There was no fog in this room. Xu Damao poked his head out and found a small room under the air duct, where he could clearly see two men adding something to the blower.

When they heard the sound of metal breaking and saw Xu Damao coming out of the hole, they couldn't help being startled. They picked up the screwdriver and shovel beside them respectively, and rushed towards Xu Damao.

Xu Damao saw clearly that both of them were in their 40s and [-]s. They were ugly, with scars on their faces and necks.
Xu Damao didn't dare to be negligent, he took out a few stones from his pocket with his right hand, and lifted them lightly, the two of them were hit by the stone bullets and fell down on their backs.

"Who are you? Tell me the truth?"

"Humph!" One of them suddenly pulled out a long knife from his body, and used the Ditang knife technique on the spot, almost cutting off Xu Damao's feet. Fortunately, Xu Damao's nerve reaction speed has surpassed the limit of human beings, and this escape is extremely fast, which is worthy of the name. can be avoided.

In the other person's hand, a little bit of cold star also flashed, Xu Damao knew it was a hidden weapon, his body turned sharply in the air, avoiding one dart, but another dart hit his shoulder.

Xu Damao suddenly felt a numbness in his shoulder and lost consciousness partially.

The darts were drugged!

Xu Damao secretly rejoiced that he had just bought all kinds of antidotes to hide on his body at the Bamiancao specialty drug store across the road, that is, the store with various snake antidote formulas.

Seeing that Xu Damao was injured, the two felt at ease and retreated quickly, waiting for Xu Damao to be poisoned.

But Xu Damao decided to fight quickly, and there was a sound of piercing through the air with one punch, forcing the two martial arts masters to retreat quickly.

Xu Damao continued to pursue and kept driving them towards the hole in the wind tunnel.

Suddenly, one of the two covered his nose and said, "No, shut up, this idea has broken the wind, if we stay any longer, we will be anesthetized!"

"Withdraw!" There was another flash of cold light in another person's hand, and an Emei thorn flew straight towards Xu Damao, Xu Damao lowered his head to avoid it, the two had already opened a secret door on the side of the room and fled in.

How can a hidden door stop me?Xu Damao kicked down the door, and saw a room full of various weapons, such as knives, guns, halberds, axes, hooks and forks, whips, maces and hammers, all kinds of ancient weapons, and they are antique, as if they were all imitated from unearthed objects old.

There are two other people in this room who are practicing lifting the stone lock. When they saw the previous two fleeing, they hurriedly stopped them.
