A man travels through time and becomes a widow, only wanting to pursue a career

County Magistrate Bai and Chen Changsheng walked around and arrived at a yard on the outskirts of the city.

The young man dismounted first and knocked on the courtyard door rhythmically. The person inside heard the sound and opened the door, revealing a head.

After seeing the person clearly, the courtyard door was opened completely, and the waiter in black said respectfully, "Your Majesty the County Magistrate."

Bai Xiao and Chen Changsheng then dismounted and entered the courtyard, which was quite large.

As he walked, he said, "This workshop was specially built by me for Dr. Xu to experiment with black powder."

Chen Changsheng saw a lot of charcoal and other materials piled up in the yard, and people dressed as craftsmen were busy. Looking at Mr. Xu in the hall in the distance, he was pacing back and forth in the workshop, and the lumps of earth under his feet were almost broken by him.

"Master Xu, County Magistrate Bai is here." The waiter in black announced.

Xu Tan walked out with a sad face, "Brother Bai, you're finally here!" Seeing Chen Changsheng beside him, he said with a smile on his face, "Mrs. Chen is here too? This time you have brought me something good. News?"

Another news came from Shangjing, saying that the border country of Yue was becoming more and more troublesome, and the Holy Emperor ordered Xu Tan to make the black powder within one month, otherwise he would never want to return to Shangjing again.

In the past few days, he couldn't eat or sleep because of this incident. He lost five pounds and no longer looked as handsome as before.

Bai Xiao nodded in affirmation, "Mrs. Chen came with the formula of black powder. We are here specifically for testing this time."

"Okay, okay, let's do the test now."

Xu Tan immediately removed the rest of the people in the workshop, leaving only two personal guards standing guard outside the workshop door to prevent anyone from breaking in.

Chen Changsheng spread a piece of tissue paper on the table, took out a mask and put it on his face.

Xu Tan looked at what Chen Changsheng was wearing on his face and asked dumbfounded, "What is Mrs. Chen doing?"

"This is called a mask." Chen Changsheng slowly poured the nitrate and sulfur charcoal powder prepared in advance onto the straw paper, then slowly folded the paper, rolled it tightly, and finally tied it tightly with a rope.

"These powders are too fine and can easily injure the spleen and lungs if accidentally inhaled into the nose, so I put on a mask to isolate myself."

Xu Tan said in confusion, "I have only seen women wearing veils and hats when going out in Beijing to prevent outsiders from seeing their faces. I have never seen Mrs. Chen wearing a mask like this."

Chen Changsheng glanced at him.

Xu Tan also wanted to ask why Chen Changsheng's mask was blue, and whether it was made of some kind of silk or some new product, but he was interrupted.

"Master Xu, Magistrate Bai, the gunpowder is ready. Let's go to the open space and try it out."

Xu Tan was dumbfounded again, "Is the black powder ready now?"

Was it done as quickly as they spoke?

So simple, so casual?

Why couldn't his craftsmen figure it out after months of research?

When he was stunned, Bai Xiao and Chen Changsheng had already walked out of the back door of the courtyard.

Behind the yard is a soil slope, with more than a dozen soil pits of various sizes. Some of them still have residual black marks, presumably from previous experiments.

Chen Changsheng carefully held the bundle of gunpowder, and then took the long string used to detonate the gunpowder, "Let's go, let's go to that slope to test it."

Xu Tan and Bai Xiao followed.

She first placed the gunpowder bag on the pit as she did the first time, then found a few larger gravel blocks and pressed them on top of the gunpowder bag. Then she applied a layer of wax oil to the string and stuffed one end of it into the pit. In the gunpowder bag, he took the other end and slowly moved back and unfolded it.

After all the fuses were extended, Chen Changsheng and his party were about five or six meters away from the black powder bag.

She looked at Xu Tan and Magistrate Bai, "Master Xu, Magistrate Bai, after lighting this fuse, all of us must run back immediately, as far as possible."

Xu Tan said nonchalantly, "The black powder bag is two feet away from us. It should be enough for me to retreat here."

He only took a few more steps back.

So far, Xu Tan still doesn't believe that the formula given by Chen Changsheng can be successful.

Chen Changsheng kindly persuaded, "This pack of black powder weighs about half a kilogram. The power of the explosion can kill a wild boar. The lethality is no joke. Master Xu, are you sure you don't want to retreat further?"

Hearing that it could kill a wild boar, Xu Tan's mouth froze slightly, and he immediately retracted what he had just said, "I'd better retreat further. My life is much more important than the wild boar."

Its skin is not as thick as the wild boar and cannot withstand frying.

Bai Xiao, who was on the side, frowned slightly. After thinking for a moment, he said in a deep voice, "Mrs. Chen, please step back as well. I'll provide the lead."

He believed that his skills and movements were more agile than Chen Changsheng's, and he could wait until the fuse was lit before retreating further away in time.

Besides, how dare you let a woman risk her life to light the gunpowder while he and Mr. Xu were two grown men hiding behind.

Chen Changsheng was not polite to Magistrate Bai. After all, her life was also her life. And there are no big rocks to hide from this time. Let men do such a dangerous thing.

After explaining the precautions to Magistrate Bai, she took out a mask from her sleeve and gave it to Bai Xiao, and then immediately stepped away.

Bai Xiao imitated Chen Changsheng's example and put on a mask. After confirming that Chen Changsheng and Xu Tan behind him were within a safe range, he lit the fuse with a fire stick, and then quickly retreated.

When he had just retreated and stood still, he heard a loud "boom".

When the thick smoke slowly dissipated, the pit was instantly blown into a deeper pit.

Xu Tan was overjoyed and patted Magistrate Bai's shoulder vigorously, "Success! Brother Bai, we have really developed black powder! Ahem!"

Because he was so excited, he took a few puffs of thick smoke and coughed several times.

After taking a breath, he realized that Bai Xiao was also wearing a mask, and he was the only one with a bare face.

"Mrs. Chen, why am I the only one without a mask...ahem..."

"Sir, you retreated too quickly just now. The civilian woman didn't have time to..."

Xu Tan said carelessly, grinning his big white teeth at Bai Xiao and Chen Changsheng, "The black gunpowder has been successfully developed. Brother Bai and Mrs. Chen are the two of you who take the lead. I, Xu Tan, will write a letter to explain the situation. I will definitely Let the Holy One reward you well."

This time with black gunpowder, I am no longer afraid of the Moon Kingdom.

"By the way, we also need to arrange those masks! No wonder those craftsmen used to cough all the time. They must have hurt their bodies from breathing powder all day long. I want to give these masks to my craftsmen and those in the mine. All arranged.”
