Zhao Hanzhang attached great importance to spring plowing and repeatedly warned: "This land has been opened for you, so you must not delay spring plowing."
Pingxun agreed and was stunned for a moment when he saw Zhao Hanzhang mounted his horse, "Is the envoy about to leave?"
"I was passing by and stopped by to take a look. You guys should be busy."
Ping Xun could only watch them riding away with regret. He also wanted Zhao Hanzhang to visit the Yushan Hall.
However, there is a long time to come. The Yushan Hall has just been built a few days ago, and the results cannot be seen yet. Once they have finished the fields, built the school, and the children have achieved success in their studies, you will be able to see them when you return.
’s achievements.
Zhao Hanzhang and Fu Tinghan came out today to test explosives.
A group of people went into the mountain, a stone mountain. Most of the stones for building houses in Luyang City were collected from here, but now it is difficult to mine, so they changed to a different mountain.
The mountain was deserted, and Zhao Hanzhang had people surround the mountain to prevent idlers from approaching. Then he brought Fu Tinghan over to test it.
Qiu Wu brought two wooden barrels up, put them down and saluted, "My lady, I have brought everything."
Fu Tinghan opened the lid of the barrel, and inside there were bamboo sections as thick as a child's arm.
He carefully took it out and motioned to Zhao Hanzhang to look at it, "It's just filled with gunpowder. I haven't tried it. I'll take a look at the effect today and then prepare the formula."
He took out a box from the bottom of the barrel and opened it. Inside was a roll of wire.
Qiu Wu felt his fingers hurt when he saw this rolled thread. He twisted the thread using paper, not a very big strip of paper. He wrapped it with a little saltpeter powder, then rolled it up carefully, and then brushed it again.
After the rice is pureed, it is dried.
This long roll of thread was all twisted by him. Qiu Wu didn't understand why he, the head guard, would do such a thing.
Fu Tinghan's hands were quite dexterous, and he put the thread into the bamboo joints lightly, and then twisted the bamboo joints together.
Qiu Wu counted and found that there were twelve bamboo knots in total.
Fu Tinghan looked at the mountain, finally chose the side of a big rock and put down the bamboo joint, and then began to pull the wire outward.
After pulling it out a long way, he cut the thread.
Seeing that he was ready, Zhao Hanzhang ordered: "Let everyone retreat, stay away from this mountain, and squat down to watch."
Qiu Wu: "Ah?"
Zhao Hanzhang glanced at him.
Qiu Wu immediately responded: "Yes."
He immediately told the soldiers and guards to retreat.
Seeing that they all retreated to a safe area, Fu Tinghan took out the fire stick, blew it, and when the fire came out, he squatted down and lit the fuse.
The fuse made a clicking sound, and then quickly burned all the way...
Zhao Hanzhang picked up Fu Tinghan and trotted out. After running far away, he covered his ears and squatted on the ground.
Several guards of Qiu Wu saw it and hesitantly touched their ears. They were hesitating between covering or not covering their ears. Suddenly there was an explosion and everyone's heart jumped. Qiu Wu subconsciously drew out his sword, and his heart almost jumped out.
, when he raised his head, he was shocked to see the stone mountains in the distance with smoke rising into the sky.
"this……"
The guards and soldiers panicked for a moment, and then they and Qiu Wu stared at the rocky mountain that made a loud noise.
When the smoke and dust dissipated, the mountain of rock that had been difficult to mine collapsed, and the blasted stones were scattered all over the ground.
Zhao Hanzhang was very excited, so he grabbed Fu Tinghan and rushed up to take a look.
Seeing that the exploded area was quite large and was filled with falling rocks, she nodded with satisfaction, "This is quite powerful. Is it because of the good formula you used, or because of the large amount used?"
Fu Tinghan also looked at the stones on the ground and felt that the power was too great. "Try again. Try it with only six bamboo sections later."
Zhao Hanzhang nodded.
They re-selected the blasting location.
Qiu Wu couldn't calm down for a long time, let alone other guards and soldiers. This... seems a bit powerful.
Qiu Wu began to follow Zhao Hanzhang and Fu Tinghan step by step. Seeing Fu Tinghan tying the thread again, he couldn't help but lower his voice and asked, "Da... Da Langjun, did you make this thing?"
Fu Tinghan tied the thread and handed it to him, "You have just seen how to light it. You can try it now."
Qiu Wu took it nervously, and Fu Tinghan patted him on the shoulder and said: "Don't be afraid, this thing will not explode unless there is a violent collision or fire."
Qiu Wu became even more nervous.
No wonder the great man asked them to carefully escort the contents of the bucket when they went out this morning. They must be careful to escort them.
Qiu Wu carefully carried the gunpowder up the mountain, placed it on the position chosen by Fu Tinghan, and then put the thread and walked down.
Naturally, it is impossible to pull the line down the mountain. The remaining mountain road is rugged and not easy to run.
So Zhao Hanzhang didn't let Fu Tinghan come forward, and went up to light the fuse himself.
Seeing that the fuse was heating up rapidly, Zhao Hanzhang turned around and jumped down the mountain with Qiu Wu. The two of them were flexible and jumped down the mountain in three or five steps. Then they ran a long way and jumped into the gully dug before.
When she and Qiu Wu fell down, there was a loud bang on the mountain. Fu Tinghan kept counting the time in his heart and raised his hands to cover her ears when she fell.
He knew that her hearing was sensitive, and loud noises were uncomfortable for them, let alone her.
Qiu Wu had been paying attention to protection, and when he saw the young man holding their girl in his arms and covering their ears, he frowned and leaned obediently in the ravine, waiting for the explosion to pass.
This time the explosion was much less powerful, but a lot of rocks were thrown out.
Zhao Hanzhang was very satisfied with what he saw, "It seems that this formula is very successful. It is just the first trial and there is no need to modify it at all."
She asked Fu Tinghan curiously, "Do you usually study this?"
Seeing Fu Tinghan frown slightly, he asked, "Why, can't you say it?"
Fu Tinghan's brows widened and he shook his head and said: "In the past, this was kept secret, and it really couldn't be said. But now it doesn't matter."
He said: "I have participated in military industry research before, mainly helping them calculate some parameters. Some laboratories contain early arsenal data. Because it is a confidential project, sometimes it takes several months to get out. I
I was bored, so I read all the information available in the laboratory."
Those things can be regarded as historical materials, and the weapons and equipment have been improved many times, so they are only used to understand the hardships and struggles of our ancestors, and do not prevent people in the laboratory from borrowing them.
"I have a good memory, so I chose a formula from it. It was just a preliminary try. I didn't expect it to be so successful."
Zhao Hanzhang said: "After all, it is a mature formula."
Fu Tinghan nodded, this research is very labor-saving, because everything that should be available is available in this era, and it does not require a lot of effort.
Qiu Wu ran over excitedly, "Girl, Da Langjun, do you want to blow up the remaining six tubes?"
Fu Tinghan thought for a while and then said: "This one-tube, two-tube, or three-tube explosion is just a test of their power."
Qiu Wu was eager to give it a try, "Girl, this is too dangerous, let me leave the rest to my humble position to lead the way."
Zhao Hanzhang nodded, waved his hand and said, "Go, be careful."
