Space at hand: Pick up a prince to farm

Chapter 256 Discovery of Nitre
This should have been the entrance to a cave before, but now there is a large piece of ice around it.

These ice blocks have blocked most of the entrance.

Cang Er stood here and watched for a long time.

I finally discovered why there is such a big piece of ice here.

There was a stone not far in front of him, as well as some leaves and other random things scattered on the ground, and the entrance to the cave seemed to be covered with a layer of hoarfrost except for the areas that were not covered by ice.

But it's not actually frost.

He remembered that his master had said before that in addition to making gunpowder, saltpeter could also make ice.

This ice should be formed by the condensation of saltpeter when it encounters water.

When Song Chen and Cang Liu came over, Cang Er was still carefully studying why the saltpeter would freeze into ice in such a natural environment.

"Have you noticed anything after looking at it for a long time?"

When Song Chen saw these ice cubes, and then saw the environment here and those hoarfrost-like things, he almost understood.

He asked Souji with a smile.

Cang Er turned around when he heard Song Chen's voice and felt a little embarrassed when he saw the teasing look in Song Chen's eyes.

"Miss Song, I really don't understand."

Cang Er touched his head and continued, "I heard my master say something before that in order to get usable saltpeter, we need to refine it. I really don't know how these things can be found here."

Song Chen stepped forward and scraped a little on his hand, "The ice here probably only appeared in the past few days. It was not discovered before. It is probably related to the previous explosion."

Song Chen couldn't be sure and could only make his own guess.

"These stones and weeds should also be a kind of proof. I have encountered something like this there before. It was a stone extending out. I thought it was very solid, but after I went up, I found that it was loose. , after jumping down, the stone had already fallen into the mountain stream."

Song Chen originally didn't plan to talk about this matter, but now that he saw this situation here and made this guess, he brought it out.

Sure enough, Cang Er and Cang Liu's reactions made her dumbfounded.

The faces of the two grown men turned pale with fright. Before, she was just frightened, but now looking at them, she felt like they were surviving the aftermath.
"I tell you this not to surprise you, but to make it clear that this situation is not accidental."

If the rocks were loose in only one place, it would be considered normal, but they encountered two places in succession, which is something to ponder.

"Let's collect these hoarfrost-like things here first and take them back, and then ask your master to find someone to mine them. There is probably a saltpeter mine here."

Song Chen felt that the saltpeter powder must have slowly seeped out from the inner layer, and then just in time for the rain, it exploded on her side.

Shaking away the stone that originally blocked the entrance to the cave was equivalent to taking away the umbrella above a person's head to protect him from the rain.

It is normal for pure saltpeter powder to freeze when it meets water.

Cang Er and Cang Liu quickly followed Song Chen's words and took out the small porcelain bottles they had on them.

The previous contents were ginseng pills, which had been eaten by them long ago, so they were reluctant to throw away the bottle.

Song Chen is not the kind of person who only talks and doesn't do anything.

Cang Er Cang Liu was collecting saltpeter powder there, and Song Chen also found a place to start doing the same work.

It took them almost half an hour to collect all the white frost-like things they could see.

This work is really very delicate. They have been working for so long and scraped off everything they can collect here. In the end, each person has not collected a full bottle.

"When you put these things on your body, don't expose them to open fire for the time being." Song Chen warned them after putting away his share.

If there is an accident, it means that someone has some flammable items with him, and the saltpeter burned on the fire will cause big problems.

Cang Er and Cang Liu carefully put their things away and followed Song Chen back.

The sky outside has darkened. It is said that it is easier to go up the mountain than it is difficult to go down the mountain. Now they are going to take the path down the mountain.

After dark, dangers lurk everywhere on the mountain, and wild beasts like to come out at this time.

The target of the three of them is too big at the moment, and they may have been targeted long ago.

"Cangliu, I am in front and you are behind."

Cang Er had already sensed a hint of crisis and quickly adjusted his way forward.

The two of them planned to protect Song Chen in the middle, so that they could respond promptly no matter where the situation occurred.

"No need, you go, I'll stop you."

Song Chen rejected Cang Er's kindness, "I always carry medicine with me. First of all, poison cannot get close to me. If I encounter a beast, I also have medicine to buy time."

Everyone knows that she can make medicine, and she can also use medicine to deal with beasts, insects, and snakes.

Song Chen's words were no longer lying.

Although she planned to slowly fall behind and then quietly release the white tiger.

They are still in the hinterland of the mountainside, which is the most dangerous place.

Although Cang Er and Cang Liu didn't doubt Song Chen's words, they didn't want Song Chen to cut off the queen. This really didn't make sense.

"How about, Miss Song, share some of the medicine on your body with us? This way, Miss Song, you don't have to terminate your pregnancy."

Song Chen: "." Why is it different from what she thought? This Cang Er is a bit crazy!
Others have asked for it, so why don’t you give it to me?

And as you said before, these medicines are useful. .

Song Chen silently took out two medicine packets from the space and handed them to the two of them, "These are anti-poisons. You can also wear them on your body in the future. The effect of the medicine can last for ten days."

She originally made this medicine bag for herself, so the outermost layer of cloth still had some small patterns on it. The two of them looked at the lumps on it and felt a little funny. They really didn't know whether they should hang it on their waists. .

In the end, the two of them thought about it and decided to hang it on their waists. For the time being, they would hang it on their waists under their coats.

"Um, Miss Song, please wait here for a moment, and we'll be back as soon as we go."

After saying that, the two of them ran to hide behind a big tree nearby to hang the medicine bag.

The distance is about four or five steps, as long as the tree is big enough.

Song Chen looked at the two people's actions, his eyes flickered, and he quietly hid behind a few nearby trees, and quietly released the big white tiger.

When she was in the space, she had already communicated with the big white tiger, came out quietly, and then quietly protected them.

After leaving the space, the big white tiger jumped out like lightning.

Cang Er noticed something was wrong and turned his head suddenly.
