However, Lan Zhi soon thought that in the world of technology, photolysis is the last step in solving the problem.

Before photolysis, it is completely possible to perform physical adsorption.

The intrusion of filthy gases is in some way the equivalent of a toxic chemical spill from the tech world.

In the aftermath of a toxic chemical spill, the most environmentally friendly methods are physical adsorption, recycling, and UV irradiation.

If it is a simple small leakage, it should be adsorbed or absorbed with sand or other non-combustible materials.

If a large amount of leakage is encountered, a levee or pit is dug to contain it, covered with foam to reduce evaporation, and then pumped to a special collector for recovery.

The rest was really pumped with a pump, so it was handed over to the sun for photolysis.

The filth on the courtyard can be treated as a small leak.

There is no doubt that the preferred option is physical adsorption.

The filthy abyss can refer to the plan of a large number of leaks, first build an embankment to prevent it from spreading outward, and then make a device to collect the filthy gas and burn it with the fire of the golden crow.

The rest can't be collected, and then photolysis is carried out.

Thinking about it like this, I instantly felt that Yan Yuan was not a big deal.

However, it is too early to talk about the matter of Yan Yuan.

The top priority is to solve the problem of filth in the courtyard first.

After solving the problem of the Ruling Court and the Pinglan Star Academy, it is not too late to move the Filthy Abyss.

Lan Zhi slapped his palm with his fist and set off to find a material that could absorb filth.

She rummaged through her collection and found the stone.

It's just that the stone alone is not enough.

It would be better if it was paired with a material that can actively absorb filth gas.

Lan Zhi searched in the encyclopedia of medicinal materials in Zhihai and found five or six possible suitable materials, two of which were common medicinal materials, she ran to the Medicine Repair Pavilion to get the materials, and immediately started making them.

It's just that the filthy beast can't enter the Pinglan Star Academy, and she has no way to test whether it works or not, so she can only hand it over to Yu Siji to try.

Yu Siji looked at the flat and flat thing the size of a jade pendant: "How to use this?" ”

Lan Zhi didn't think about this problem when he did it, and thought about it for a while: "Do you want to put it in your mouth?" Take it out tomorrow and the day after tomorrow to see if there are any changes. ”

This question reminded Lan Zhi.

Lan Zhi immediately thought of a more effective way of adsorption - swallowing.

Swallow the adsorbent material in the shape of an elixir, absorb the filthy gas in your stomach and then pull it out.

She told Yu Siji about her thoughts and calmed Yu Siji on the spot.

What the hell is this idea?

But if you think about it, it doesn't seem impossible.

Yu Siji had thought of many ways in the past, but he was always limited to the habitual thinking that the pill would be absorbed by the body, and only thought about what pill could be used to resolve the toxicity of the filthy gas, and never thought that the pill could be used in reverse.

After Lan Zhi brought it up, she suddenly realized that the reason why she had been unable to solve the problems of the head of the courtyard and herself for so many years was because her way of thinking was imprisoned.

- She unknowingly fell into a mental trap.

At this moment, Yu Siji completely understood why she was able to pull up the Pinglan Star Courtyard, and also understood Yi Wengui's shock.

Because, Lan Zhi's thinking has no walls!

After Yu Siji's mind opened, he quickly thought of several spiritual plants that could absorb filthy qi.

She's a doer and thinks of doing it right away.

Lan Zhi sat next to her and suggested that if she wanted to discharge it safely and harmlessly, the pill should not be too big, it was best to make it into a long strip, and it should not expand after absorbing filthy gas and body fluids, and it should not be absorbed by the body......
