The next moment.

Old Yao suddenly turned around and looked at Chen Ji: "What is so strong and domineering!"

Chen Ji: Huh?

No, old man, are you really wrong?!

Chen Ji didn't know the meaning of this hexagram, but old man Yao said "strong and domineering", wasn't that the characteristic of gunpowder?

Old Man Yao stared straight at Chen Ji: "I didn't expect you to have such ability to make such a thing. Why are you making this thing? Do you want to rebel?!"

Chen Ji quickly said: "No, no!"

But I heard Old Man Yao say: "Do you know that if this matter is revealed, you will die without a burial place? Don't say that I won't protect you, even the Ning Dynasty will not tolerate you."

Chen Ji was silent. He was not sure what Old Man Yao's stance was. If the other party really wanted to report him, he would have no choice but to escape.

It's a pity that he has just established himself in this medical center and thought he could settle down and live here.

Chen Ji raised his head and said, "Master, I didn't think about it..."

Old Man Yao interrupted: "The hush money is six taels."

Chen Ji: "?"

…

…

The main hall of the medical center was dim, and a cool autumn night breeze swept through the windows, causing the flames of the oily lamps to sway, and the light and shadow cast on Chen Ji's face.

"I've said so much with you, just for hush money?" Chen Ji said calmly.

"No," Old Yao said calmly, "I'm not doing it to make money, I'm doing it to save your life."

Chen Ji was heartbroken: "Did you know that six taels of silver can buy a lot of things?"

Old Yao stroked his beard: "I know, I can buy you to build a ladder for Princess Baili."

Chen Ji: "..."

The co-author knows everything, so no wonder the amount is exactly the same as the two tolls!

Old Man Yao sneered: "The hospital is my hospital. The prince and the princess pass by me. Is there anything wrong with paying the toll to me?"

Chen Ji said: "Then I also worked hard, I moved the ladder for them!"

But he saw old man Yao return to the main room, and actually brought a bamboo deck chair out and placed it on the corridor between the main hall and the backyard: "I am here to let you relax, and I have also done my work. Pay me six taels."

, you can do what you want to do with peace of mind, as long as I am watching over you, no one can find out."

The huge bamboo lounge chair was as light as a toy in the hands of the ninety-two-year-old man.

Chen Ji: "...Is this still possible?!"

Old Man Yao didn't care about that, he just stretched out his hand firmly: "Where's the silver peanut?"

Heartbroken, Chen Ji took out the six silver peanuts from his sleeve and patted them on Old Yao's hand.

Old Yao happily put it into his sleeves, hummed a little tune and lay on the bamboo couch with his eyes closed to rest: "Abiding by the law makes you depressed in the morning, but Qiangliang sings joyfully every night..."

Chen Ji looked at the other party in silence for a long time, confused as to what to do with the old man.

Finally, he gritted his teeth and said: "Master, don't say I didn't warn you. If you accept the money, you will be an accomplice in the future!"

Old Man Yao chuckled softly: "Threaten me? You are still young, I want to see what you can make."

Chen Ji stopped talking. He added white water to the pottery bowl and placed it over an oil lamp to slowly heat it until the water temperature rose to about seventy-five degrees.

There was no formal way to measure temperature in this era. Chen Ji only knew that when the water reaches 80 degrees, the bottom of the bowl will start bubbling. Once it starts bubbling, remove the oil residue lamp and wait for the water temperature to slowly cool down for five minutes.

The temperature he wants.

Chen Ji also took soil saltpeter and plant ash, put them in a pottery bowl at a ratio of 8:1, stirred them slowly with a bamboo skewer for a quarter of an hour, and then filtered them slowly with rice paper.

Old Yao didn't know when he got up, but he stood aside and watched attentively.

Chen Ji ignored him and boiled the soil and salt water again until only one-third of the water was left in the bowl.

He removed the oil residue lamp and concentrated on waiting for the thick liquid in the bowl to slowly cool down.

When the liquid in the pottery bowl dropped below human armpit temperature, Chen Ji took a drop of the liquid in the bowl with a bamboo skewer and tapped it gently on the counter.

But when the drop of liquid met the cold counter, it instantly condensed into transparent crystals, just like pouring water into ice!

Old Yao's eyes suddenly widened.

Chen Ji breathed a long sigh of relief: It’s done!
