Pick up a female emperor as a wife

If Qin Chuan wanted to soak in the hot springs, why did he have to look for a cave?

The two are not related!

Even though she was doubtful, Ouyang Ronger had a sinister plan in her mind.

Going to find a hot spring, right?

I've poisoned you!

So, she replied: "Sir, there is a mountain outside the imperial capital called Tangshan. There are several hot springs in this mountain. There are caves in the mountains. Rong'er doesn't know the exact location, but if you look for it patiently, you should be able to find it."

"That's a good answer. I'm very satisfied!" Qin Chuan nodded.

Ouyang Ronger sneered in her heart. There were indeed hot springs in Tangshan, but there was a yellow poisonous gas around the hot springs. After inhaling the poisonous gas, one might feel dizzy and bedridden for days at the very least, or even lose one's life at the worst!

If Qin Chuan went there, inhaled the poison gas and became bedridden, how could he deal with her? !

So, she urged, "Sir, since you asked where the hot spring is, go there immediately."

"There's no rush for this matter. I still have some things to prepare in advance. You should just do what you need to do now." Qin Chuan's attitude towards Ouyang Ronger was unusually nice.

"Hmm? Is this guy scared? Does he know there is poisonous gas near the hot spring?"

Ouyang Rong'er thought about this and asked tentatively, "Sir, why don't you go now?"

"Didn't I tell you? You need to prepare in advance. If you ask any more questions, I will punish you according to my family rules!" Qin Chuan became ferocious.

Ouyang Ronger was so scared that she covered her chest and dared not say anything.

"Why are you covering it? There's no breast at all!" Qin Chuan said disdainfully.

Ouyang Ronger was so angry that she wanted to explode, but she suppressed it, which made Qin Chuan laugh a few times and then he walked away.

After arriving at the backyard, Qin Chuan ordered Tian Tianci to go to the street to buy charcoal, dried pigskin and sheepskin, wood, nails, hammers, copper pipes, and kettles.

Although Tian Tianci didn't know why Qin Chuan did this, he knew that as long as he obeyed Qin Chuan's orders and did his job well, he would get benefits.

Sure enough, Qin Chuan gave him one hundred taels of silver. After he bought what he wanted, he gave him the rest as traveling expenses.

Niu Dali was arranged to stand in front of the door to the backyard. Without Qin Chuan's permission, no one else could come in.

An hour later.

Tian Tianci bought everything Qin Chuan needed.

He spent thirty taels and kept the remaining seventy taels in his pocket.

Qin Chuan asked him to put the things in the yard and sent him out, asking him and Niu Dali to guard the backyard door well. No one could come in without his order.

That's why!

This is because Qin Chuan wants to make gas masks and gas gloves.

Ouyang Ronger thought that he didn't know there was poisonous gas near the hot spring, which was really underestimating Qin Chuan.

Undeveloped natural hot springs almost always have toxic gases nearby, and the toxic gases produced are what Qin Chuan wants to get.

sulfur!

Why do you want this?

Of course he wanted to make explosives!

Only in this way can there be enough firepower to deal with the assassins who want to assassinate the emperor.

Qin Chuan also thought about making guns, cannons and so on, but iron tools were not very popular in the Daqian Kingdom, and the smelting technology could not be compared with modern ones.

Although Qin Chuan studied chemistry, he could still make some simple instruments in ordinary experiments. However, if he was asked to make guns and cannons, it would be a bit difficult for him.

Explosives do not require such a strong level of craftsmanship as a basis; they can be made as long as gunpowder is produced.

To make gunpowder, three things are important: sulfur, nitrate and charcoal.

Most sulfur mines are found in areas where there was once volcanic activity or hot springs, which is why we need to look for hot springs.

Most caves contain saltpeter soil. After the ancients discovered the function of saltpeter, they would boil saltpeter in the caves and extract the saltpeter from it.

It can be found on the exterior wall tiles of some old houses, in the soil near pig, sheep and chicken pens, and even on some saline-alkali land.

It’s just that these are just exposed on the surface and the quantity is not much.

The cave had accumulated minerals for hundreds of millions of years before it was discovered, and the content is very considerable.

When Qin Chuan was in Qingtian Village, he was able to make ice in the summer by using saltpeter.

However, the areas near undeveloped hot springs and sulfur are poisonous. If you don't take precautions, even if you are not poisoned on the spot, you may live many years less because of the sulfur entering your body.

Therefore, he must wear a gas mask and gas gloves before going to look for sulfur.

The most important part of a gas mask is the poison gas filter, and activated carbon is the best material for filtering poison gas.

It is also quite troublesome to make. The charcoal needs to be crushed first, the finer the better.

Then two furnaces are needed.

Connect the kettle to the charcoal stove with a copper pipe so that the water vapor in the kettle will enter the charcoal stove.

As the water vapor continues to be injected, the charcoal will turn into activated carbon after at least two hours.

However, the process requires continuous high temperature, and the temperature of ordinary carbon furnaces cannot meet the requirements. At this time, the help of bellows is needed.

Let Tian Tianci buy wood, sheepskin and pig skin to make bellows.

Qin Chuan doesn't want anyone else to come in, naturally because he wants to protect his intellectual property rights.

If everyone else knew about his modern knowledge, it would be worthless.

Qin Chuan did not waste any time and started making it immediately.

In a blink of an eye, two days and two nights passed.

Tian Tianci and Niu Dali were indeed loyal. They ate, drank, and slept in front of the backyard door, and they took turns going to the toilet.

The servants in the mansion were no longer surprised to see Qin Chuan busying around in the backyard, and they had no intention of going in to find out what was going on.

Ouyang Ronger, on the other hand, often wanted to come over during the past two days.

She didn't want to know what Qin Chuan was doing, she wanted to know when Qin Chuan would go to the hot spring?

She really wanted Qin Chuan to be poisoned and unable to take care of himself.

In this way, she would have the opportunity to escape back to the Ouyang family.

Just when he was about to ask Niu Dali and Tian Tianci to go in and ask Qin Chuan when he would go to find the hot spring.

Qin Chuan, who had not been out for two days, finally came out.

Qin Chuan's face was covered with dust, as if he had just come out of a coal mine.

Before Ouyang Rong'er could speak, Qin Chuan ordered, "Are you a maid without vision? This young master needs to take a bath, why don't you go and boil some water!"

"Young Master, are you still going to the hot spring?" Ouyang Ronger asked bravely.

"Of course I'll go." Qin Chuan replied.

Ouyang Ronger showed joy on her face. Even though she disliked Qin Chuan very much, Qin Chuan was about to go find a hot spring. Once she was poisoned, she would be able to escape from the suffering. How could she not be happy?

She said with a smile: "Sir, Rong'er will go and boil some water for you."

To Ouyang Rong'er's surprise, when she boiled hot water for Qin Chuan to pour into the bathtub, she saw Qin Chuan taking off his clothes on the ground in front of her without even saying hello...

See Qin Chuan naked.

Ouyang Ronger was stunned!

This was the first time in her life that she had seen a man's body.

Even though she is a lady from a wealthy family and even though she looks down on most men, the law of opposite sexes attracting each other still applies to her.

She instinctively looked down and saw something she shouldn't have seen...

When she was about to take a closer look, she found Qin Chuan was staring at her and smiling.

She was so scared that she immediately closed her eyes and said, "You, you are so vulgar, you took off your clothes in front of Rong'er without even saying hello."

"Haha, you secretly looked at me without even saying hello, isn't that a bit too much? You have ruined my innocence!" Qin Chuan laughed.

"I wasn't looking at you!"

Ouyang Ronger turned around and ran out of the room.

When she heard Qin Chuan's laughter getting louder and louder, she felt extremely ashamed and angry, and her face became very hot. She ran out of the house in one breath, and only then did she feel a little better.

Thinking of the scene just now, Ouyang Ronger stomped her feet in anger!

"Humph, disgusting Qin Chuan is so vile! This time I will definitely poison you and make you unable to take care of yourself!"

An hour later, Ouyang Ronger finally returned to the mansion.

At this time, Qin Chuan had already washed and changed his clothes. Niu Dali was carrying a huge bamboo basket, and Tian Tianci also picked up a shoulder pole. Because it was covered with cloth, she couldn't see what was in it at all.

She didn't care what was in the carrying pole and the bamboo basket. She only knew that Qin Chuan was ready to go.

This time, she will take Qin Chuan to the place with the most poisonous gas!

She took the initiative to become enthusiastic: "Sir, let Rong'er lead the way for you!"
