Only children in Siheyuan make choices. I want them all.

Upon hearing this, Wu's father shook his head repeatedly and firmly rejected his son's proposal.

"No! Absolutely not! If you use a gun, the nature of this matter will change, and there will be no way to end it. You can just bring a few more people and steel pipes!"

The eldest brother, Wu Lingyu, nodded: "Dad! Leave this matter to me. I will arrange the manpower today and take them directly to his house in the evening."

Father Wu patted his eldest son on the shoulder and nodded with satisfaction: "I'll leave this matter to you. Your brothers are too impulsive and prone to bad things. Okay, let's do it this way. Let's act together in the evening."

After the four members of the Wu family finished their discussion, they all went back to find helpers. Zhang Jianjun also returned home and prepared the medicines needed for body training.

"Take off all your clothes! Use this iron sand to rub your skin all over your body until your skin turns red." Zhang Jianjun took out a basin of iron sand from the space and handed it to Lawrence.

"Ah! Why do you do this? Isn't this self-harm? Can you tell me the principle?" Lawrence was holding a basin of iron sand, a little at a loss.

"Stop talking nonsense? Just rub it when I tell you to! This can speed up the blood circulation in your skin. I'll give you a medicinal bath later. Hurry up!" Zhang Jianjun urged and took out the big wooden barrel from the space.

"Okay!" Lawrence could only nod helplessly and began to rub the iron sand on his skin.

"Use more force!" Zhang Jianjun urged.

"Okay!" Lawrence increased his strength and began to rub with iron sand until his skin all over his body turned bright red. Only then did Zhang Jianjun let Lawrence stop.

"It will be very painful to soak in the medicinal bath now! If you can hold on, you can continue to practice martial arts. If you can't hold on, I can't do anything. It means you are not suitable to learn my kung fu. Do you understand?" Zhang Jianjun asked seriously with a dark face.

"I understand! Don't worry, Master. I will definitely persevere." Lawrence was full of fighting spirit and answered with gritted teeth.

"Okay! I believe you." Zhang Jianjun nodded and motioned Lawrence to soak in the medicinal bath.

Lawrence took a deep breath and went directly into the wooden barrel. As soon as his skin touched the medicinal bath, he screamed: "Oh my god! Fuck! Shit!"

Lawrence struggled to climb out of the barrel. Zhang Jianjun saw that the situation was not good and simply held down his head forcibly.

"What? Do you want to give up? Are you all cowards in the Lawrence family? I trained like this in the beginning! If I can persist, why can't you? Hold on! Hold on! For the honor of the family."

Zhang Jianjun knew that the stupid foreigner valued the family honor more than his own life, so he deliberately provoked him.

"Yes! I will persist. I will not bring shame to the Lawrence family. Come on! Master, give me a stick and I will bite it in my mouth!" Lawrence said with gritted teeth, as if he was ready to die.

"That's not necessary! As long as you hold on for two or three minutes, you will slowly get used to it. Everything is difficult at the beginning! If you persist, you will be able to practice to the level of being invulnerable to swords and guns." Zhang Jianjun smiled and shook his head. He felt that Lawrence was exaggerating a bit.

"Okay! I'll listen to you." Lawrence could only grit his teeth and persevere. Sure enough, after two or three minutes, the burning pain gradually subsided.

Lawrence also regained his composure. The power of the medicine slowly invaded his meridians. Lawrence felt sleepy and slowly closed his eyes and fell asleep...

Seeing this, Zhang Jianjun quietly stepped back. He wanted to talk to Qin Jingru about life and ideals, and also ask her what was missing at home.

"Brother Jianjun, why are you here? Where is your apprentice? Has he gone home?" Qin Jingru, who was preparing lunch in the kitchen, greeted Zhang Jianjun warmly when she saw him.

"No! He is taking a medicinal bath, so don't disturb him. By the way! Is there anything missing at home? I'll go buy some now." Zhang Jianjun asked with a smile.

"Oh! We need nothing. You just need to go there. Why do you need to buy anything? Brother Jianjun, you just wait in the house for dinner. Leave the cooking to me." Qin Jingru pushed and shoved Zhang Jianjun out of the kitchen.

"This girl! Really! Forget it, I'll just buy some rice, flour, grain, oil, etc. Rural people are simple and unpretentious. If you buy them high-end cigarettes and alcohol, they will be reluctant to eat and drink."

Zhang Jianjun, who came from a poor family, knew very well what the lower class people needed. Instead of buying them Moutai liquor or Zhonghua cigarettes, it would be better to buy them something practical.

Qin Jingru quickly prepared lunch, which consisted of four dishes and a soup. Although the taste was not as good as Zhang Jianjun's, it was not bad either, and it tasted like a home-cooked meal.

"Brother Jianjun, where is your apprentice? Ask him to come over for dinner!" Qin Jingru asked curiously.

"Are you talking about him? He will probably sleep until night. Don't worry about him. Let's just eat first." Zhang Jianjun said, and started to show off his food with big mouthfuls.

After lunch, Qin Jingru blushed and said a little embarrassedly: "Brother Jianjun! Why don't you not go back to sleep at noon? I want to have a good chat with you."

Zhang Jianjun knew what Qin Jingru was thinking, so he didn't refuse. He smiled and nodded: "Okay! Jingru, I won't go back at noon. Let's have a good chat about life."

Nine thousand four hundred and fifty-three words are omitted here...

Time passed quickly and it was night. Lawrence woke up slowly and saw Zhang Jianjun staring at him.

"Master, why are you looking at me? Let me tell you, I'm not gay. You can't have any improper thoughts about me." Lawrence crossed his arms across his chest, pretending to be resisting.

Zhang Jianjun was so angry at his apprentice that he started to curse: "Fuck! What the hell are you thinking? I'm watching how your skin absorbs the medicine. How do you feel now?"

Lawrence then realized that he had misunderstood and scratched his head embarrassedly: "It feels good. I am full of strength now. I can kill a cow with one punch."

Zhang Jianjun nodded: "Not bad! It seems that your physique is very good and it fits well with this medicine. I estimate that in about ten days, you will be able to achieve some success."

Lawrence was a little confused at this time: "Master! Can I really practice to be invulnerable to swords and guns like you said? Is this scientific? I always feel like you are lying to me."

"I believe you when you say it can strengthen my body, and I also believe it can increase my strength several times. But as for making it invulnerable to swords and guns... I really don't believe it." Foreigners are like this, they say what they think and never know how to beat around the bush.

Seeing that Lawrence didn't believe him, Zhang Jianjun picked up the fruit knife on the table and handed it to him: "Stab me with the knife! Stab anywhere! It doesn't matter if it's my arm, thigh, or body."

Lawrence waved his hands hastily: "No! I dare not, this is illegal."

Seeing that he refused, Zhang Jianjun took the fruit knife from Lawrence and stabbed himself in the chest.

There was a crisp "ding" sound, and the fruit knife seemed to have stabbed into steel, and even the tip of the knife was broken.

"How about it? Do you believe it now?" Zhang Jianjun handed the half-broken fruit knife to Lawrence.

Lawrence's eyes widened. "Fuck! Master, are you serious? I believe you, I really believe you this time! Master, I surrender. I will practice martial arts with you in the future."
