Chapter 175 (2/2)

The red and black eyes were the same as before he left. It seems that she has been used to the life of an abnormal creature in her body.

”Because you need to eat.” Sighed. Jiang Chenli said of course.

He was a little tired of that humiliating expression. But this chick seems to like it or not?

”I said,” have you been bullied out of a sense of block? ” Looking at Lin Ling, whose face began to write and draw on the touchpad, Jiang Chen said helplessly.Obviously, she has a face that is not inferior to that of a beautiful girl. She has to show such a bad expression.

”Go to hell.” After drawing the last stroke with her finger, Lin Ling gave Jiang Chen a fierce look and made a face with her tongue out.

”What is this?” Jiang Chen ignored her action and approached the edge of the touchpad and asked.

”Ha ha, stupid --” Lin Ling raised her chest and raised her mouth.

”Cough.”

”Ah! That's enough! Well, I'll say it She pouts out her mouth in frustration. Lin Ling points her finger on the screen. ”The first step is neutralization of pH value, the second step is to remove heavy metal ions with ion filter, and the third step is”

”and so on. What is an ion filter screen?” Jiang Chen stopped her words and asked.

”Something that can easily filter out a specified relative atomic mass should be common.” Lin Ling said casually.

I've never heard of it.

At this time, Jiang Chen suddenly recalled that Lin Ling had been staying in the Research Institute, or she would not have no idea about the situation of the last world. In this way, what she said was common in the laboratory.

”Let me first ask, how many steps do you need in these processes?” Jiang Chen asks with black lines all over his head.

”Not much, not much, just 24 processes. I have sampled and tested the soil here, and the pollution level is 68. I can't believe that such poisonous soil can still grow weeds. ” As soon as she was good at the field, the expression on Lin Ling's face also became excited.

”Don't you think about the cost when you're in the lab?” Jiangchen make complaints about it.

”Cost? Of course I will Lin Ling didn't think so.

”After more than 20 processes, can you tell me what the cost is?”

Lin Ling took a strange look at Jiang Chen.

”Have you misunderstood something? ”Eden Project” is not a ”soil purification project”. Since it is a sub project of space colonization, why do we have to study how to control the pollution of the earth. With organic matter and minerals from other planets, we can make soil. It's too much of a hassle to purify

”Making soil?”

”Yes, it's not difficult to make soil, at least much easier than washing. However, there are already contaminated ”finished products” everywhere. It seems that it is not easy to find pure raw materials for soil synthesis. ” Lin Ling sighed.

Making soil? Other planets?

Jiang Chen suddenly patted his head and swore in his heart.

I didn't think of it. Why is it so troublesome? I can cross both sides! Grain can be moved back. How hard is it to get hundreds of cubic meters of mud?

Now that the problem has been solved, Jiang Chen does not intend to continue with this problem, so he digs the topic.

”Well, let's not talk about this. By the way, have you finished the task assigned to you?” (to be continued.).. )
