What Xu Han designed was a set of pulleys.

The pulley is simple to make, because Zhao Yan is very good at this aspect, and Bai Yan is very fast as long as he has drawings. If the pulley method is feasible, it is fixed at the top of the cliff, and the iron raw material at the bottom of the cliff is transported by iron cable, so that the time of the intermediate travel is greatly reduced, and the number of transportation is greatly increased.

"Shinu, is this thing really useful?" Bai Yan was a little unsure, after all, although they had used this thing before, they had never used it on such a high cliff.

"Try it." Xu Han saw that after the pulley was installed, he walked over and asked the guards to move some things into the iron frame, which was surrounded by railings all around, even if the iron frame was toppled over, the things put in it would never be poured out because of this.

Hearing an order, the guard standing in the distance waved the flag in his hand, and the guard standing at the top of the cliff saw that the flag moved, and immediately repeated the actions of the guard at the bottom of the cliff. After some reincarnation, the guards in charge of operating the pulleys immediately became operational.

Before half an hour, there was a clattering sound from the top of the cliff, and the flag on it moved, and they received it!

"Great! This method really works! Zhao Yan, who was standing next to her, excitedly grabbed Xu Han's shoulder and was overjoyed, "The tiger mother has no dog girl, and the daughter of the world is worthy of being the daughter of the loyal and righteous marquis!" Sure enough, the wisdom is unparalleled! ”

Xu Han also showed a relaxed smile on his face: "Since this method is feasible, then this iron raw material is easy to do." She looked at the iron frame slowly lowering on the cliff and added, "This thing is too heavy, they still have to be more careful when lifting it up, in case there is an accident, and it will be difficult to fall from it." ”

Zhao Yan immediately nodded in response, and then emphasized the precautions again to all the guards who were responsible for transporting the materials.

With the help of pulleys, raw materials from Wonju were quickly transported in a steady stream.

On weekdays, the blacksmith shops extinguish the fire in the stove to save some firewood. But here, the iron furnaces in each room do not stop, and as long as it is time to enter the furnace room, you can start working immediately.

After the problem of raw materials is solved, Xu Han is most worried about the quality problem. Although she had repeatedly emphasized that she should not cut corners, she and Bai Yan had been together for a long time before she realized that many times the things made could not be completely accurate.

So she simply ate and lived with Bai Yan and them every day to supervise the daily progress.

Just as they were rushing to make weapons day and night, Lu Guo was about to move.

"Where are you going to go?" Out of the dragon tent, the eldest princess saw that the eighth princess sister she hated was carrying a bow and arrow, and she didn't know where she planned to go, so she stopped her.

Bazana looked at her expressionlessly: "What the hell is going on with you?" ”

"You!" Mu Sha glared at her hatefully, and said coldly, "Don't think how great you are, in a few days, I will let you cry in front of me!" Hum! ”

Bazana still stood there expressionless, not looking at her the whole time.

After Makusha left, she raised her feet and walked out. He didn't go far before someone stopped him, and it was the military advisor Zhuo Yila.

"The Eight Princesses' actions are inappropriate."

"Get out of the way!" Bazana's voice was resolute.

"Eight princesses, I believe that you must also want to let Yan Kingdom divide the river and rule, but now you have seen it. Ever since the princess designed to kill Xu Liuzhou, the king has lost confidence in you, and instead began to pamper the princess. If it goes on like this, I'm afraid that the princess will be embarrassed. ”

"Then you don't have to worry about that. Hongu will figure it out. ”

"I know that the princess is not afraid, but have you thought about it, is Yan Guo still willing to reconcile now? Even if someone advocates reconciliation, then Xu Han, the daughter of the loyal Marquis Xu Liuzhou, is she willing to reconcile? As far as the minister knows, the relationship between this Xu Han and the regent is not ordinary! Maybe she's the one behind the manipulation! ”

Bazana thought of the woman who had broken into the court that day and rejected her with a faint smile, and was silent. The woman did have a demeanor and momentum that she didn't have, but ......

"What do you want to do?"

Zoira smiled and leaned closer to Bazana's ear and said, "It's better for us to find the black oil first, and then treat others in their own way." In the last battle in Zhuzhou, the king is still heartbroken! ”

Bazana's eyes narrowed.

"How?"

"The minister has already found manpower, as long as the princess nods, she can set off at any time!" Seeing that Bazana was so happy, Zoira immediately said excitedly.

"Okay, let's go now!"

Just as Bazana and Zoira are busy looking for black oil to solve the present? Huan Cheng Bao? Qian _ has already dealt with the affairs in the capital, and brought a team of guards to Zhuzhou to inspect the production process of the crossbow.

It was a small soldier in the outer circle who led him into the mountain, and when he reached the village through the layers of protective rings, Xu Han was debugging the completed crossbow in the backyard.

It is said that it is a backyard, but in fact it is an empty field, and the original trees have been cut down to make a house, and the open space that has been split up can be used for practice. Because of the long range of the bed-running crossbow, the arrows they used were rudimentary.

"Miss Report, this time the range is one thousand and twenty-three meters!"

Xu Han frowned, and did not speak to the smiling expression of the guard, but lowered his head and played with the bed crossbow in his hand. She remembered that the crossbow could be adjusted, and now that she had adjusted it to the farthest range, it was only one thousand and twenty-three meters, which was not enough.

"Did you shoot?"

The guard with a smirk was stunned, shook his head, and said, "Miss Report, I didn't shoot!" ”

She gave her a blank look: "What are you stupid about if you didn't shoot?" ”

The guard immediately scratched his head and muttered, "Miss Report, although you missed the shot, it hit a tree next to the target." ”

Xu Han immediately lowered his face and reprimanded: "In case you shoot the people next to the enemy again, are you still happy?" ”

At this time, I listened to a rough thanks? walked out from behind her and said lightly: "The world girl is really getting more and more like a general." ”

When Xu Han heard this, he was stunned, and he was stunned for a while before coming back to his senses, but he didn't take his words, just frowned, lowered his head and continued to do his own thing.

Seeing her react differently than she usually sees herself, thanks? Her eyes narrowed slightly, and her heart turned slightly, guessing her thoughts.

The guard didn't know how to thank you? But the one who can come here naturally can't be an idle person, so he retreated very interestingly, pretending not to hear the conversation between the two.

The open space was huge, leaving only the embarrassed two.

"You ......"

Thank? The heart is exquisite, but after a while, I guessed why she was awkward with herself.

"Bang!"

A cacophony interrupted his words.
