"This microorganism uses organic matter as a nutrient source. It needs organic matter for its growth and prefers organic compounds of iron and manganese. When the organic matter is used, the iron and manganese will be excreted as waste and attached to the filaments of the bacteria."

A lot of concepts of chemically mixed organisms are thrown around, and many people are a little confused.

【I understand, what about you?】

[I understand, it’s very simple. Isn’t it just a kind of microorganism? You don’t even know this? 】

[Scratching my head, am I the only one who doesn’t understand? 】

[Did you listen carefully when Teacher Fang was in class? You will be punished by copying a hundred times!]

[Copying and copying]

"It's a little dark now. I guess it may rain next. Let's fish them all out now. Otherwise, it will be inconvenient to fish them out when the river rises. There is also the possibility of being washed away. Let's look for them nearby next.

, there should be quite a few more.”

Iron bacteria generally live in slightly acidic water that contains less oxygen but more dissolved iron and CO2. An alkaline environment is not conducive to their survival. The surrounding environment should be acidic.

All the yellow mud was fished out. The back part had turned brown and was accompanied by a peculiar smell, but Bifang did not stir it up at all and fished it all out.

The entire bark frame sank.

After pulling out all the iron bacteria in the small holes, Bi Fang looked in other directions, not missing every small hole, and actually found two more places.

Before the third spot was dug, little ripples began to appear on the water.

It's raining.

Bi Fang wiped away the water droplets that were about to drip from the tips of his hair and accelerated his digging speed.

"The rainy season is really annoying. It rains every three days. It may be sunny when you go out during the day, but within an hour, it will rain heavily. Fortunately, this rain does not seem to be very heavy."

After all three holes were dug, Bi Fang was also soaked.

Fortunately, almost one-third of the bark frame is filled. With this amount, it is more than enough to make an iron sword.

[It feels very confusing. Can you practice so many things? 】

"That's enough. You don't know how heavy they are, and they feel exactly like iron sand. That's more than enough."

Bi Fang covered the bark frame with leaves to prevent rainwater from entering too much and flowing out through the gaps, then he carried the big frame on his back and chased in the direction of the white-legged bison.

Entering the rainforest, the rain becomes much lighter.

"If I had known better, I should have made a raincoat in advance." Bi Fang ran around with his head in the woods, searching everywhere, and finally found an arched structure full of vines.

Thick vines grow in a curved way, leaving a large space inside.

Bi Fang lifted it up and looked around for large leaves to cover it. He simply tied it and drilled it inside, and the wind and rain were immediately isolated.

"Unfortunately, the situation is a bit urgent. The leaves are not tied up and may be washed away when it rains. I hope this rain can end soon."

Bi Fang wiped the mud on his body and sprinkled it, then grabbed a large number of palm leaves stained with iron bacteria from the bark frame and began to weave.

"To nip it in the bud, we should prepare a raincoat in advance so that the temporary shelter will not be washed away and I will have to run around again."

"Many people should have heard of coir raincoats, lone boatmen and coir raincoats, fishing alone in the cold river snow. In fact, many coir raincoats are made of palm leaves. Of course, the effect is not as good as those made with authentic coir raincoats, but it is enough for us.

used."

Palm leaves can be used to weave a relatively simple coir raincoat. The process is fast, but it is relatively thin and has poor rain protection effect.

The coir raincoats made of coir raincoat are relatively thick and have sleeves, which are very effective in keeping out the rain and can also keep you warm.
