Yuwentu saw the words on Yang Fan's paper, his face suddenly changed, and he continued,

"Xianxu rest assured, Miss Qi Yan is all right now, when you finish making the soil mine method tomorrow, the old man will let you meet the two of you, but Xianxu don't forget, Bingyan is your wife!"

Yang Fan nodded, and then left the City Lord's Mansion.

Returning to the humble bedroom where Yuwentu gave alms, Yang Fan felt bitter in his heart, because the distress letter sent out to deliver to Li Yuan's father and son was politely rejected by Li Yuan, and Li Yuan refused to snipe Yuwentu halfway on the grounds of lack of military food, which made Yang Fan's design of the abacus fail.

"Li Yuan's father and son are also selfish, and the alliance they said was left alone, in this troubled world, it seems that no one can be relied on!"

Yang Fan was helpless, sighed and lay on the bed.

Although Yuwen Tu said that Yuwen Bingyan was his wife, he didn't even give himself a chance to meet her, and even the room was separated from him.

Fortunately, Yang Fan is accompanied by Wei Chi Jingde, who can protect Yang Fan and transmit outside news for him.

At dawn the next day, after a simple breakfast, Yang Fan was called away by Yuwentu's soldiers.

According to the material formula provided by Yang Fan last night, Yuwentu has already arranged for the next person, and yesterday he ordered someone to find saltpeter, sulfur and other things overnight.

Yang Fan made it according to the drawings he designed, and then handed the closed earth mine to Yuwentu, who came to supervise the work.

Yu Wentu looked at the black pimple in his hand, padd its weight again, and returned it to Yang Fan, signaling him to show the power of the earth mine!

Yang Fan didn't dare to slack off, wrote down the use of soil mines on a piece of paper, and then threw it to the soldier he didn't like.

However, Yang Fan deliberately set the ignition line of the soil mine to a fast-burning line, and shortened the length of the line by two-thirds.

The soldier who walked to the big pit not far away with the earth mine trembled his hands at this moment, and his body couldn't help but tremble.

Yu Wentu was a little impatient, and hurriedly urged,

"Don't grind, hurry up and show the old man the power of the earth mine!"

Hearing Yuwentu's urging, the soldier had no choice but to pick up the fire fold on his body and light it.

However, the fire excerpt seems to have made a joke with him at this time, and he didn't blow a little spark after blowing for a long time.

He blew more than a dozen breaths in a row and finally blew the fire fold, and he didn't dare to slack off at the moment, and immediately went to the fuse!

"Boom! ——”

A violent explosion was heard, and before the soldier could throw away the earth mine in his hand, he was shattered by the earth mine's body!

Yuwen Tu and Yuwen Bingyan were both taken aback, naturally they didn't expect this little black bump to be so powerful!

"This ————"

Yu Wentu looked at the little soldier who sacrificed for the experiment, and his heart was surprised and happy, without the slightest pain and frustration.

Yang Fan pretended to be helpless and wrote on the paper,

"This mine needs to be improved, remember to be careful when using it!"

Yu Wentu looked at it, nodded again and again, and then asked Yang Fan to try it out and teach those soldiers to make soil mines.

Yuwentu's madness surprised Yang Fan a little, this guy got saltpeter and sulfur from almost every place, and the entire Lu City was piled up with saltpeter and sulfur like a mountain.

……

At the right night, under Yang Fan's repeated requests, Yuwentu finally agreed to return Qi Yan to Yang Fan.

When Yang Fan saw the distressing Qi Yan who was covered in scales and had a weak figure, he felt deep guilt in his heart.

Qi Yan's face was still cold, she just glanced at Yang Fan and turned her head.

Yang Fan secretly swore in his heart that he must rescue Qi Yan from Yuwentu's territory, and how he treated Qi Yan, he would definitely make him repay ten times or a hundred times.

Yang Fan picked up the pen guiltily and wrote on the paper,

"I'm sorry to make you suffer!"

Qi Yan didn't speak, and fell silent again.

Yang Fan knew that Qi Yan must have regretted following him, otherwise there would never be a bad situation now.

Yang Fan picked up the pen again and wrote on the paper,

"I promise you, I will definitely do it, unless I, Yang Fan, die!"

Yang Fan's eyes were red, and he put the content on the paper in front of Qi Yan.

Qi Yan looked at the above content, her eyes were a little surprised, and finally she opened her mouth,

"It's not your fault, you don't need to feel guilty......"

Qi Yan's words were weak, Yang Fan lost control for a while, and suddenly hugged her in his arms.

"You, what are you doing......"

Qi Yan didn't have the extra strength to push Yang Fan away, and her tone was pale and weak.

Yang Fan just hugged her tightly, and for some reason, he couldn't control it for a while.

Fortunately, Qi Yan's weakness made Yang Fan have to let go of his hand, and then helped Qi Yan to the side of the bed and lay down.

Yang Fan picked up the pen again and wrote on the paper,

"You can sleep with me tonight, don't worry, I won't take advantage of others."

Yang Fan's words made Qi Yan stunned for a moment, and then nodded weakly.

……

This night, Yang Fan stayed in the prescription of the City Lord's Mansion, and thought of the secret recipe of Pei Yuan Guben in the Xuanhuang Baolu, and began to make it.

In the middle of the night, Yang Fan walked to the bedside with a lantern and a hot decoction, looked at Qi Yan, and picked up the words that had already been written in his hand.

"I'll drink the medicine later, don't worry, I'll definitely let you recover as before!"

Yang Fan looked at the sunken scar on Qi Yan's face, and there was a trace of bitterness at the corner of his mouth.

Qi Yan looked at Yang Fan with a rare smile,

"I know you're going to cure me! I believe you! ”

Yang Fan and Qi Yan's eyes were intertwined, and in an instant, Yang Fan's heart gave birth to the idea of taking Qi Yan for himself.

"Marry me, Qi Yan!"

Yang Fan blurted out, and he actually spoke at this moment.

Qi Yan was stunned for a moment, looked at Yang Fan and said in surprise,

"You, what did you say? How could you ......"

Yang Fan didn't know what was going on, he really wanted to say this sentence in his heart just now, but he knew that it was impossible for his vocal cords to say this sentence at this time, so he deliberately said it, but he didn't think that his voice was inexplicably better, and he was a little embarrassed for a while.

"I, I ......"

Yang Fan really wanted to find a crack to get into at the moment, this kind of explicit and domineering confession was not his intention, and he didn't know how to explain it in the face of this embarrassing situation at this time.

Qi Yan still opened her mouth and said,

"Although I have some crush on you, we can't, and I don't want to regret it later!"

Qi Yan's categorical words made Yang Fan's heart cold, such a tragic situation of being thrown home was really unbearable.

Yang Fan scratched his head and said,

"Okay, just let me say it!"

Qi Yan suddenly laughed, she looked at Yang Fan, her eyes were full of tenderness,

"Unless, unless you can restore my looks, then I'll ......"
