Chapter 230 (1/2)

asement.

The body wall is not used to block anything, but to deliberately.

The purpose is to have only one point.

This kind of corpse wall is used to create the atmosphere of ”underground cemetery”.

Increasing the total amount of Yin Qi in underground area, better pathogenic fungal environment, and conducive to the cultivation of ghouls.

It's not just the homes of Han Dong and others.

The basements of other buildings have similar structures, but the underpass structure will not be found until the excavation is deeper.

Han Dong's residence here is just separated by a wall.

In addition, the basement passage has a heavy pollution smell, and most people don't know where to go. Without enough information, no team will go into it rashly.

Han Dong comes to the basement alone.

The original wall was cut open again to reveal a passage full of pollution.

”Sure enough There is a direct access to the ghoul factory. ”

When Han Dong walked to the end of the passage filled with bacteria, a hard to break solid stone wall sealed the road, leaving a keyhole.

If a man destroys the stone wall with brute force, it will be devoured by ghouls like tide.

As for Han Dong.

Dong Dong Dong Dong!

Just knocking on the stone wall.

After waiting for no more than two minutes, the stone wall immediately turned over and opened

the ”swelling doctor”, whose head is about three times the size of an ordinary person, is standing in the internal passage, slightly lowering his head and rubbing his small hands to welcome Han Dong's arrival.

When an intruder was detected by a detection device and further confirmed as a ”messenger in yellow”, Dr. swelling immediately left his work at hand.

Get on his Ghoul mount and rush to Han Dong's knocking position.

A ghoul mount with tubes in his skull and a chain around his neck is holding him.

”The Lord is not below?”

”Not in Messenger, please come in. Go to my private lab and talk, so that the walls don't have ears. ”

The remodeled Ghoul mount is quite good, adding a cushion at the back groove as a seat, and climbing speed is comparable to that of ordinary horses

in a laboratory strengthened by multi-layer iron doors, the legend of human body analysis is drawn on the large blackboard, and each area is extended through dotted lines, and the detailed description of the apparatus and tubes is made, which constitutes a systematic system Human body diagram.

The table was full of conical flasks, alcohol lamps, funnels and beakers.

The glass display cabinets on both sides store all kinds of experimental drugs and related living samples.

Dr. swelling's desk is full of documents and drafts Most of them are about ghouls.

However, there are some limitations in this way.

You don't think of some things that you are familiar with before.

”Is the messenger also proficient in experiments?”

Han Dong did not answer directly, but pointed to one of the distillers.

”There are some problems with your simple distillation device. The distillation separation effect should not be very good, right? Purity is very important.

You can make a multi-stage distillation unit by using a crucible, a distillation furnace and two or four U-tubes. In addition, a uniform heat transfer layer is added to the whole unit to maintain a constant temperature.

In this way, the distillation and purification efficiency can be greatly improved

”You, my Lord!”

Han Dong points out the key to the problem.
