There are still four days left before Ling Yi and his son publicly executed. Bai Xiao’s relationship with relatives has been discovered. Bai Xiao currently has a mother, two sons and one daughter, and he originally had three sons. One of them was just killed some day ago.

It turned out that after Bai Xiao killed King Shi, he once seized the opportunity to kill one of Bai Xiao's sons to avenge King Shi. However, this subordinate was still caught by Bai Xiao and the cruel Lingchi was executed.

Therefore, Bai Xiao has arranged all his relatives to live in the palace, and the guards of the palace have also been replaced by his own confidants, and the focus has been on protecting them. It will not be easy to catch these people again.

Qian Xiaoxing fell into despair after listening to the report. Unexpectedly, this method would not work. His hopes were shattered, which brought great disappointment.

Everyone sat around the table, and there were still four days to make a rescue plan. Everyone was silent and seemed very serious. Ling Shan could no longer help but worry in her heart and cried, "Brother Xing, you must save my brother and father!"

Li Ting also begged: "Qian Xiaoxing, save him, think of a solution."

Shi Yeying hurriedly said, "Don't worry, Xiaoxing must have a solution."

Qian Xiaoxing shook his head in pain and said, "This time, I'm afraid everyone will be disappointed."

Ling Shan immediately burst into tears when she heard this. Li Ting said excitedly: "Qian Xiaoxing, aren't you very good at inventing things? Why don't you invent submachine guns and kill them?"

"Submachine gun?" Qian Xiaoxing smiled bitterly and said, "Not to mention submachine guns, I can't afford to even gunpowder guns. Not to mention gunpowder guns, I forgot how to do it!"

"Ah!" Li Ting screamed in surprise and said, "I really don't know what you learned in school. I have forgotten all the four great inventions of ancient times."

Qian Xiaoxing said helplessly: "I only remember that gunpowder is made of three kinds of things, one of which is charcoal, and I really can't remember the other two. By the way, do you know?"

Qian Xiaoxing always wanted to invent gunpowder, but he just forgot the formula. Now Li Ting has also traveled through time. If she knew, that would be great. Qian Xiaoxing could only place all her hopes on her. Li Ting said excitedly: "If you forget, you should say it earlier. Gunpowder is made of saltpeter, sulfur and charcoal. I remember the ratio of three items is 75 to fifteen to ten."

"Wow! That's great!" Qian Xiaoxing was excited and said, "I have invented the four great inventions, papermaking, compass, and printing books. I forgot this gunpowder, and now I've got it all."

After hearing the conversation between Li Ting and Qian Xiaoxing, the others didn't understand at all. Shi Yeying asked curiously: "Xiao Xing, what is the gunpowder you are talking about?"

Qian Xiaoxing felt much more relaxed. With the huge killing weapon of gunpowder, there was no task that could not be completed. Qian Xiaoxing replied: "Gunpowder is a very powerful weapon. With it, it will no longer be difficult to save Ling Yi and his son."

"Really, it's great." Ling Shan said happily when she saw Qian Xiaoxing finally had a solution: "Let's take a look at gunpowder."

"Okay, I'll give it to you immediately." Qian Xiaoxing called the soldiers of the guard company and ordered them to go out to purchase these three items. Saltpeter and sulfur are still for sale in traditional Chinese medicine stores, but the number is not large. Qian Xiaoxing also sent some other people to the surrounding cities to purchase them.

After buying back a few packs of materials from Yidu, Qian Xiaoxing immediately arranged them, mashed the three materials and mixed them together in proportion. He didn't use much for the experiment, and only mixed them with a small bowl.

Seeing that the gunpowder that Qian Xiaoxing said was ready, everyone watched. Qian Xiaoxing poured the gunpowder in the bowl to the ground, and the black powder formed a black line. Then he lit a piece of paper with a lighter and threw it at one end of the black line.

The paper burned wildly on it, and the fire gradually decreased after a while, but the gunpowder did not react at all. The more Qian Xiaoxing looked at it, the more nervous he became. Could it be that the formula of this gunpowder was wrong? Or were the materials impure?

The others also sighed, the powerful weapons they were looking forward to were useless at all. Suddenly, a "boom" sounded, and a stream of white smoke burst into flames along the line, and instantly burned all over, leaving only the black powder residue.

Everyone was so fumigated by the choking smoke that everyone coughed. Shi Yeying covered her mouth and waved the smoke, saying, "Although this thing burns very quickly, I can't see a particularly powerful part."

Seeing that the first experiment was successful, Qian Xiaoxinghuan jumped up and said, "Now it is placed on the ground and burned. If it is placed in a bottle, it will explode. Its power is quite powerful, like thunder."

"It's so powerful, Brother Xing, let's take a look." Ling Shan was looking forward to it.

Qian Xiaoxing thought about it and said, "You can't test it in Yidu City. The explosion sound is too loud and it will easily cause suspicion. Let's go out of the city."

After mixing all the materials in his hand, there were about ten kilograms of black gunpowder. Qian Xiaoxing spread out a piece of paper, then introduced a little gunpowder and rolled it up, and it could be used as a fuse. After everything was done, it was dusk. Qian Xiaoxing went out of the city regardless of the darkness.

A group of more than ten people rode a fast horse and stopped about ten miles away from Yidu City. After getting off the horse, they walked into the path. There was a hillside next to the path and there was no one around. Qian Xiaoxing decided to conduct a blasting test here.

Qian Xiaoxing brought a jar the size of a basketball, then filled it with gunpowder and compacted it. The fuse was placed in the mouth of the jar and sealed it with soil.

In order to test the power of the explosives, Qian Xiaoxing asked the soldiers of the guard company to dig a hole on the earth slope, which was about one meter deep. Qian Xiaoxing put the jar in and slowly unfolded the fuse, which was about two meters long.

Everything is ready, only the fire is not needed. Qian Xiaoxing waved his hand to let everyone retreat. Qian Xiaoxing still didn't know the power of this black gunpowder and explosives. For the sake of safety, everyone retreated for more than 20 meters.

"I count to five and then ignite the fire!" Qian Xiaoxing asked everyone to prepare and began to shout: "Five!"

The night was already dark, and the lighter flint flashed in the darkness, and the burning flames ignited the fuse. Qian Xiaoxing immediately turned around and ran quickly.

The fuse flashed with Mars and was burning forward quickly. Qian Xiaoxing didn't expect the fuse to burn so quickly. Fortunately, it was quite long. After Qian Xiaoxing ran more than ten meters, he heard a loud noise behind him, and a wave of air pushed Qian Xiaoxing to the ground. Then the mud in the sky splashed down and hit Qian Xiaoxing.

Everyone else was scared by the loud noise. Although they were prepared, they still didn't expect it to be so loud. Seeing the angrily black smoke rising into the sky after the explosion, the mud all over the sky flew over and let everyone avoid it.

Qian Xiaoxing was thrown into a dog and had a dog's shit on his face. He spitted out mud and sand in his mouth, and climbed up and said to everyone: "How do you feel about this explosive?"

Shi Yeying said: "It's very loud. I wonder how the pit was blown up?"

Everyone walked to the edge of the pit that had just been blown up and saw that the hole that was only enough to put down the jar was blown open about two meters wide, and a large pit like a pot appeared in front of them.

Smelling the familiar smell of fireworks, Qian Xiaoxing said: "It seems that the effect is OK if you just use such a little gunpowder to blow up such a big pit."

Shi Yeying asked in confusion: "Can this explosive only blow up the pit? It's only useful if it can blow up people."

"Of course, it can also be fried. I told you that as long as you add some iron beads to these explosives, there is no stone added, then it will kill people if it explodes." Qian Xiaoxing explained.

Shi Yeying replied: "This explosive is so amazing, it's much more powerful than refining bombs."

The ultimate goal of explosives is to kill the enemy on a large scale, so the explosives that add stones are what Qian Xiaoxing finally needs. Qian Xiaoxing said: "Time is tight, start the second test immediately!"

The soldiers of the guard company cut down some trees, put their coats on them, stuffed them into branches and dead grass for temporary replacement, preparing to conduct an explosion experiment.

In an open space, a circle of tree stumps were filled with explosives. The stumps in clothes stood up like scarecrows. A black pot of explosives in the middle had been equipped, and dozens of small stones had been added to it.

Everyone retreated fifty meters away, and this time Hu Suoyuan was responsible for ignition. In the dark night, Hu Suoyuan ignited the fuse and ran back immediately. Qian Xiaoxing immediately shouted: "Everyone is lying down!"

"Boom!" A white light flashed, bringing a strong wind.

Everyone couldn't wait to walk towards the explosion site, but saw that the stumps were already tilted and the clothes they were covered with torn. Qian Xiaoxing carefully checked and found that there were many small stones on the clothes that had been penetrated by the explosion. If they were replaced with iron beads, the power would be even greater.

The rest of the people were stunned when they looked at this super weapon. Needless to mention how much lethal it was, even its explosion was enough to scare the enemy.

"The experiment was successful, but we want a lot of black gunpowder. We just hope that these raw materials can be bought." Qian Xiaoxing waved his hand and asked everyone to go back to Yidu City first.

There were three days left to leave the public execution. The soldiers who purchased gunpowder raw materials from around Yidu City came back one after another and brought back some saltpeter and sulfur. However, these two materials were only sold by pharmacies, and the pharmacies usually don’t use much medicine, so there is very little inventory.

Qian Xiaoxing saw that the raw materials he bought were only enough to make twenty kilograms of black gunpowder. Even if a 10 kilogram explosive pack could only be made two. This was still too few. At least ten kilogram explosive packs were needed. Qian Xiaoxing felt confident.

"There is too little gunpowder!" Qian Xiaoxing said with a disappointment, "It's too late to buy it in other places, so it's really troublesome."

Originally, everyone thought that with this explosive, they could save people smoothly, but they didn’t expect that there was an explosive, but there was too little. Is it really impossible to rescue Ling Yi and his son?

Ling Shan walked out and said, "Brother Xing, I'll think of a solution!"

"What can you think of?" Qian Xiaoxing asked back.

"Did you forget that our family is doing business? Our family's business also involves these medicinal materials. I just hope there will be them in our Ling family's warehouse." Ling Shan said.

Qian Xiaoxing slapped his forehead and said, "Yes, why did I forget this? Those pharmacies were also purchased by you. You are the big owners. You can do this quickly."

"Okay, I'll do it now!" Ling Shan turned around and went out.

About two hours later, everyone was waiting anxiously. Ling Shan finally returned to the courtyard. Qian Xiaoxing hurriedly stepped forward and asked, "Shan'er, are there any goods?"
Chapter completed!
