After dinner, the old grandson took Li Rui into the study, pressed a hidden button, there was a slight sound of the machine, and the wall automatically turned into a door, the old grandson motioned for Li Rui to follow, and the two walked in, inside was a secret room, a row of iron shelves with all kinds of exquisite boxes, I couldn't see what was inside, and there were some antiques such as porcelain, and there were some years at a glance.

Li Rui was not interested in these things, he glanced at Lao Sun Tou and said, "Old Sun Tou, I didn't expect you to have this kind of secret room, this thing is worth a lot of money, right?" What did you bring me in here for? ”

"Many boxes contain tools handed down from the previous generation, and I will open your eyes when I turn around, in addition, I have to prepare, get you some herbs, you can soak it all night, completely eradicate the hidden dangers of the body, stimulate qi and blood, and improve the strength of the body, which will be of great benefit to you in the future." The old grandson said.

"Okay, you can dispense the medicine first, and we'll talk about the tools later." Li Rui smiled gratefully.

"It's okay, don't want to leave this time, familiarize yourself with the various tools of the master, you will definitely be able to use it in the future, in addition, this place is closed, suitable for you to soak in the medicinal bath, it will be a little painful for a while, however, you can shout casually here, the sound insulation effect is good." The old grandson smiled.

"How much does it hurt?" Li Rui keenly noticed that there was something in Lao Suntou's words and asked.

"It doesn't hurt, you can bear it, don't worry." The old grandson smiled evilly, and did not explain too much.

Li Rui knew the character of the old grandson, once the decision was made, no one could change it, nodded helplessly, and watched the old grandson open a few boxes, take out some herbs from them, bags of them, sealed very well, and then put them in an iron bucket, the barrel is as tall as a person, and the charcoal can be burned below.

Dozens of herbs were thrown into the iron bucket by the old grandson, and then poured water into it, Li Rui didn't understand the herbs at all, and couldn't see what the category was, but he believed that the old grandson would not harm himself, and waited patiently, not long after, the iron bucket was filled with more than half a bucket of water, and the old grandson took out a big bag of charcoal, threw some charcoal into the iron tong, and then poured oil, scratched and threw it on the match.

The fire burned all of a sudden, and the charcoal also burned, and the old grandson smiled with satisfaction: "The craft has not fallen yet, you can prepare it, and go down when the water temperature rises." ”

"Prepare what?" Li Rui asked in surprise.

"Of course, I took off my clothes, and also, move on the spot, relax my muscles and bones, and let the qi and blood flow faster, and it is best to sweat a little and let the pores open, so that it is more conducive to the body's absorption of the medicinal liquid, how to move without me teaching you, right?" The old grandson smiled.

Li Rui smiled, took off his clothes, and moved up wearing only a pair of underwear, a hundred push-ups, a hundred frog jumps were just done, a fine sweat broke out on his body, and the water temperature in Tietong also came up, the old grandson hurriedly stopped, signaled Li Rui to go in, Li Rui was not hypocritical, moved a stool over, stepped on the stool and climbed up, held the edges of both sides of Tietong and supported it hard, and his body fell into Tietong, and the water just had no neck.

"Old grandson, this water is a little hot, you won't burn it again, right?" Li Rui reminded worriedly.

"Don't worry, I'll control the water temperature, and you can soak in it with peace of mind." The old grandson smiled, stepped on the stool to test the water temperature, and added: "The water temperature is just right, keep it, and tell me immediately if it's high or low, we have to spend the night here tonight." ”

"Then you have to stay with me all night?" Li Rui said in surprise.

"What do you think? This medicinal bath can only be soaked once, it must be in place, otherwise it will be a waste of my good medicinal herbs, do you know how much these medicinal herbs are worth? They are all rare natural treasures in the world, ginseng is more than a hundred years old, and the whole medicine is all added up, and it is definitely worth more than five million planet coins, you have to pay me back. The old grandson scolded angrily.

"Okay, I promise to pay you back." Li Rui smiled gratefully, no matter whether this medicine is worth the price or not, the kindness of teaching the door thief stunt is not shallow.

"It's pretty much the same, take off your underwear, it's all men, no one looks at you, remember, it starts to hurt right away, you have to hold on, don't waste the medicinal materials, in the future, Lao Tzu won't be able to take this medicine anymore, it's not a matter of money, it's that some medicinal materials can't be bought in the market." The old grandson said earnestly uneasily.

Li Rui in Tietong already felt the pain, like countless ants biting, but he could bear it, quickly took off his underwear and threw it out, and he felt that the pain began to increase, and soon, Li Rui found that there were countless knives in Tietong cutting his own flesh and skin, and the pain was pumping.

"Huh? Is it a little painful? Li Rui shouted, frowning in pain, but desperately endured.

"You've survived all the difficulties in the black prison, are you still afraid of this?" The old grandson smiled evilly, with a successful expression of his plan, and threw a few pieces of charcoal under the iron bucket.

As soon as the fire was strong and the temperature was higher, it didn't take long for Li Rui to feel that his skin and muscles were about to melt, countless knives began to scrape his bones, and the monstrous pain filled his brain, and he couldn't control his screams anymore: "Ah-old grandson, did you mean it, it hurts!" ”

"This is just the beginning, it's good to get used to pain, if you want to become a master, you have to endure hardships, what is this pain? Divert your attention, think about your great enemy, think about the enemy, and you will not be in pain. The old grandson hurriedly reminded, looking at Li Rui in Tietong, for fear that Li Rui would not be able to help but rush out.

As soon as Li Rui heard that it made sense, he immediately thought of the enemy, the herdsmen who were killed on the night of the rainstorm, the soldiers of the Black Tiger Squadron, the Uncle Anli who wanted to be killed, and the sneak attack on the base of the hunter special combat team.

"Ahh Li Rui in Tietong felt that his soul was trembling in pain, and he screamed miserably, his voice was weak, revealing a little weakness, just like the cry of a dying person before he died, and then, Li Rui felt that his bones were melting.

"You have to hold on, don't give up." Old Sun Tou reminded worriedly, for fear that Li Rui would climb out.

"I want to persevere, I want to become stronger-" Li Rui believed that Lao Sun Tou would not harm himself, and subconsciously cheered himself up, and soon his eyes were dark, he couldn't see anything, and fainted with the obsession of revenge.

Seeing that Li Rui had fainted to death, Lao Sun Tou was not in a hurry, but breathed a sigh of relief, his cloudy eyes began to shine, with a happy expression, and muttered to himself: "It's good to survive until you faint, it's done, it's done." Happily, he quickly got a few pieces of charcoal out to reduce the fire and cool down the water in Tietong.
