After going up the mountain, Qin Laohan said to Yang Xuan: "How much of this oil mine should we make?"
Yang Xuan couldn't decide how much quantity to take at the moment: "You can do it first and then talk about it."
"I still lack some materials. If I want to make more, I will have to look for materials."
"Go ahead and write me a list of materials you need, and I'll buy them."
Yang Xuan is pursuing efficiency in everything at this time.
According to Prince Hui, His Majesty the Emperor is still in a critical period. It would be fine if he gets through it safely, but what if...
Once His Majesty the Emperor dies, the situation will deteriorate instantly.
At this moment, those princes are probably already mobilizing manpower to plot secretly.
This prosperous dynasty may change at any time.
In comparison, the third prince, who has no foundation, is like a lamb waiting to be slaughtered.
Except for the crown prince, no matter which prince takes the throne, he will not let anyone else go. Since the third prince has no soldiers and power, he will probably be the first to suffer.
Yang Xuan, who was part of the Third Prince's party, could not survive the overthrow of the nest.
Early the next morning, the No. 7 high-strength steel jar that Yang Xuan wanted had been sent to the mountain.
But Qin Laohan hasn't made many oil mines yet.
Yesterday, because it was already night, the required materials were not purchased, and some materials were rarely used by anyone. I didn’t know where to buy them for a while, so early in the morning, Yang Xuan took Qin Laohan to look for materials.
went.
At this time, in Yingtian Mansion, a strange atmosphere filled the officialdom.
Officials who came to attend the court early in the morning were told that the morning meeting was canceled because the Holy Emperor was ill.
His Majesty the Emperor has always been diligent in political affairs. Last time he vomited blood in court, he went to court as usual the next day, but today the morning court was cancelled.
Thinking back to some gossip that came out yesterday, it was said that the princes secretly met with some officials overnight, so the officials began to speculate.
However, no news came out from the palace, and even several princes who asked for an audience were stopped by Wang Daban.
Wang Daban only said that the dragon was ill and needed to rest.
After struggling for a day, Yang Xuan and Qin Laohan finally gathered enough materials and returned to the Secret Armory. They were originally planning to work on it overnight, but Qin Laohan said that this thing cannot be exposed to open fire, and it is best to make it during the day tomorrow.
The next day, I watched Qin Laohan, mixing collodion soaked in yellow oil with a kind of soil mixed with several ingredients, and he breathed a sigh of relief.
"These should be enough."
Yang Xuanxin said, is this big lump of mud-like stuff a high explosive that is more powerful than fireworks and firecrackers?
Qin Laohan used tools to carefully fill the sludge into large, medium and small jars, and finally added leads and sealed them.
This lead has also been specially treated, and after many experiments, the intercepted ones can burn for five breaths of time.
On Qingliang Mountain, Yang Xuan took Dong Zhang Liangbao and Qin Laohan to a forest.
"Senior Brother Tianbao, watch carefully. After a while, you can light the fuse with a torch, and then throw it out immediately. The farther away the better, do you understand?"
Dong Tianbao looked at the fist-sized jar in his hand, nodded and said, "I understand."
"Don't be careless. Once this thing explodes, its power is hard to estimate. Even if you don't have a whole body, it's considered a light thing."
Dong Tianbao nodded again, with a solemn look on his face.
After Yang Xuan and others lay down behind a small slope nearby, Dong Tianbao lit the fuse, waved his arm round, and the jar flew far away.
Seeing this scene, Yang Xuan quickly called Dong Tianbao to come over and lie down behind the slope, while counting silently in his mind.

'boom!'
A loud noise was accompanied by flames spurting out, bringing up a large area of soil, branches and leaves at the same time.
After Yang Xuan waited for a while, he led the three of them to climb up from the slope, took three steps at a time and then flew towards the explosion site.
A large crater about one meter in diameter opened on the ground, and a tree as thick as an arm nearby was bent and crumbling by the shock wave.
Yang Xuan picked up a triangular piece of iron from the ground: "Look for this kind of iron piece nearby and see where the farthest iron piece is."
After some inspection, Yang Xuan was not satisfied with this small grenade.
In his opinion, this small-sized grenade is a bit too weak. It should be lethal enough to people, but not enough to have a deterrent effect.
Next, Yang Xuan directly tried the large one. Looking at the large pit with a diameter of five or six meters on the ground and several broken trees, Yang Xuan nodded with satisfaction.
The last medium-sized one was also ordered by Zhang Junbao, who was beside him with itchy hands. The effect was as expected.
Zhang Junbao exclaimed: "We have been sleeping together with this thing for the past two days?"
Only then did Yang Xuan react, and he couldn't help but feel a chill in his back.
Yes, where they sleep these days, there is only a brick wall away from these dangerous items.
With the weight of those materials, if it exploded, let alone the four of them, the Secret No. 1 yard would probably cease to exist.
"This matter is top secret and must not be spread to outsiders." Yang Xuan said, "This matter is not only related to our lives and fortunes, but also related to the safety of the entire world."
Although the three of them didn't understand what this had to do with the safety of the world, Yang Xuan's attitude still made them nod cautiously.
When they returned to the secret courtyard, they found that the entire courtyard was surrounded by soldiers from the Beijing camp. Shopkeeper Qian was confronting a hundred households at the entrance of the courtyard, and his roar could be heard from a distance.
"This is the No. 1 secret courtyard of the Technology Research and Development Department. No one can enter without Mr. Yang's words."
The 100-year-old man said: "Mr. Qian, I am also following orders. The superiors asked us to protect this place. There was such a big movement just now, if something unexpected happens..."
Seeing this situation, Yang Xuan breathed a sigh of relief. His nerves had been tense these past few days, and such a big mistake had happened. If those sergeants went in, saw those strange things, and took them away directly, I don't know what would happen.
What happened.
Fortunately, shopkeeper Qian blocked it.
"Master Baihu, I'm really sorry. I was doing technical research in the back mountain just now, and the noise was a bit loud."
Shopkeeper Qian and Baihu breathed a sigh of relief when they saw Yang Xuan.
"Since Mr. Yang is here, it's okay. I'll take my leave now."
"It's all my fault that I didn't explain it clearly in advance. I'm really sorry that I have to drag so many brothers on this journey." Yang Xuan said, taking out a banknote and handing it over: "I'll use this little money to give the brothers tea. After all, I'm tired."
One trip.”
The Baihu wanted to refuse, but Yang Xuan said again: "It is expected that there will be such movements tomorrow. Please bear with me, brothers. Please don't refuse, Mr. Baihu."
Seeing this, the hundreds of households accepted the banknotes and said goodbye.
Yang Xuan praised Shopkeeper Qian again. If it hadn't been for him, the secret would have been leaked.
On the third day, Yang Xuan made some improvements to these jars.
For example, the large grenade was a bit heavy. Dong Tianbao could throw it far enough, but ordinary soldiers might not be able to throw it that far at all.
So an iron chain was added to the large jar.
The lid of the jar mouth has also been improved to increase the sealing and avoid moisture as much as possible.
That night, Yang Xuan went down the mountain. This was the last day of the three days agreed with His Highness King Chun.
He left Dong Tianbao and Qin Laohan in Secret Courtyard A to keep these grenades.
The first thing after coming down the mountain, Yang Xuan found Prince Hui and told him that he was going to convene a board of directors, and that all directors must be present in person at the board of directors this time.
