Doctor Ji waited until Mu Qingge left before coming over with a box of things.

"Mr. Ji, what good things did you take?" Shang Qirui was in a good mood, and when he saw Doctor Ji, he took the initiative to joke with him.

Unexpectedly, Doctor Ji actually handed over the box, but Shang Qirui was stunned for a moment: "I'm joking with you, where can I ask for your things." ”

"This thing was originally for His Highness." Doctor Ji looked a little strange.

"What?" Shang Qirui opened the box with doubts, and looked at the gray sand-like thing inside, which was even more inexplicable, "What is this?" ”

"I don't know." Doctor Ji also stretched his neck to look at it, and then explained, "This was given by Qin Ge, and it was said to be of great use." ”

"Qin Ge gave it?" Shang Qirui was even more strange, "He just left, why didn't he give it to me directly?" ”

How would I know? Doctor Ji secretly wondered in his heart, and he didn't dare to say it explicitly, so he only asked people to find water, and changed the topic: "Since Qin Ge said it is useful, let's see if it is really useful." ”

According to what Mu Qingge said, mix the sand with water and apply it to the two stones.

"Qin Ge, that kid, has a good brain, and the things he came up with shouldn't be bad. However, I still don't see what's so special about this thing. Shang Qirui didn't bother Doctor Ji's movements, but he still couldn't hide his curiosity.

"Qin Ge said, when it's done, you can see its magic." Doctor Ji said according to Mu Qingge's explanation.

"What's this thing called?" Shang Qirui simply didn't leave, sat down and waited.

"Qin Ge said, it's called cement." Naturally, Doctor Ji couldn't go, so he sat down.

"Cement? Is water made of mud? It's funny. Shang Qirui looked at Doctor Ji, "Where did you get such an interesting apprentice?" ”

"Back to Your Highness, Qin Ge, this kid...... In fact, life is very bitter. Doctor Ji also had his own plans, and carefully told about the situation of his encounter with Mu Qingge, "At that time, I went to the mountains to collect medicine. When he met Qin Ge, who was recovering from a serious illness, his body was very weak, and it was difficult to take two steps. But he had to collect medicine alone, he didn't understand medical science, so he went to study medicine in order to treat himself. That day, he encountered a poisonous snake in the mountains, and his body was inflexible, and he was bitten by a poisonous snake. Seeing that he was dying, he just happened to run into me. Actually, I don't know how to save him, but he told him which herb can cure the snake venom. Later, he insisted on worshipping me as a teacher, saying that he was repaying the grace of saving his life. But in fact, his medical skills are much better than mine. Looking at Qin Ge's appearance, although he is an orphan, he also looks like a ...... from a good background."

"That's right, that kid doesn't look like an ordinary person in terms of courage or insight." Shang Qirui listened to Doctor Ji's words, and became even more curious about Qin Ge, secretly thinking that he must ask how he became an orphan in the future. If you can, you must help him.

"Your Highness, Weichen has a sentence, I don't know if to ask." Doctor Ji hesitated for a long time and then spoke.

"If Mr. Ji has anything to say, just ask." Shang Qirui was still immersed in Qin Ge's story.

"Your Highness, And, the fifteenth miss of the Mu Mansion, do you have any grudges?" As soon as Doctor Ji finished asking, he came into contact with Shang Qirui's cold gaze, and the hatred and anger contained in it made Doctor Ji Jun tremble.

Xu noticed his gaffe, Shang Qirui retracted his gaze, took a deep breath, and his eyes became extremely profound: "What she owes me is more than just a life......

Doctor Ji didn't understand this, and he didn't dare to ask more. But he sighed in his heart, owing someone a life is already a big enough hatred, and Mu Qingge owes Shang Qirui more than just a life. This made Doctor Ji deeply worried about Mu Qingge's future situation, and he didn't know how Shang Qirui would react if he knew that Qin Ge was Mu Qingge?

"Why did Mr. Ji mention her?"

Shang Qirui asked calmly, but Doctor Ji felt the pressure: "I suddenly thought of it, she is also a poor child." ”

"Humph......"

Shang Qirui snorted lightly, and before he could say the rest of the words, he was interrupted by Doctor Ji: "It's done." ”

Shang Qirui was cold for a moment, and only then did he understand that what Doctor Ji was talking about was the "cement" given by Qin Ge.

"It doesn't seem to be anything special......" Doctor Ji muttered to himself as he looked at the two stones in his hand.

"I'll take a look." Shang Qirui went to get the stone, but accidentally fell to the ground.

Suddenly thinking of something, Shang Qirui's eyes lit up.

He tried hard to break the two rocks apart, but was unsuccessful. He threw stones on the ground and struck them with other stones, but he did not succeed.

Doctor Ji's face was also getting more and more surprised, and he glanced at Shang Qirui, and the two sighed at the same time: "Great! ”

With such strong cement, there is no need to worry about the construction of the embankment for a long time.

"Qin Ge also said that this cement is waterproof, and it will not disperse no matter how long it is soaked in water." Doctor Ji worked hard to express the characteristics of Mu Qing's cement.

"So good?" Shang Qirui's joy can no longer be described in words, "Where did this thing come from?" ”

"Qin Ge gave the recipe for making cement." Doctor Ji handed a piece of paper to Shang Qirui.

"Great!" Shang Qirui excitedly took the recipe, "It's not very difficult, send someone to repair the kiln immediately, go quickly!" ”

Hu Li was the first to get the news and rushed over, and he also sighed loudly when he saw the success of cement. Shang Qirui hurriedly dispatched people to repair the kiln and find materials. Everyone was busy for a while, but everyone was happy.

"Mr. Ji, where is Qin Ge? I'm going to see him! Shang Qirui's search is still in a state of excitement, and he hasn't been so out of shape for a long time.

"That ......" Doctor Ji said with sweat on his forehead and hesitation, "Qin Ge said, Your Highness, the most important thing for you at the moment is to hurry up and build the embankment. The rainstorm may come suddenly, and the sooner the embankment is repaired, the sooner the people of Wucheng will be safer. He said that when His Highness repaired the embankment, he would come back to congratulate His Highness. ”

After saying that, Doctor Ji was a little afraid, after all, the other party was a high-ranking prince. In case he was unhappy and had to go to see Qin Ge, he couldn't stop it.

Shang Qirui suddenly calmed down when he heard this, he didn't expect that he had lived for so long, but he was not as far-reaching as an eleven or twelve-year-old child. The emergence of such a thing as cement is gratifying, but more importantly, it is necessary to repair the embankment.

"I see." Shang Qirui actually hugged his fist at Doctor Ji and said, "Thank you, Mr. Ji." ”

Doctor Ji almost jumped up, avoiding Shang Qirui's salute: "This, this has nothing to do with Weichen, this is all Qin Ge, Qin Ge said and did it." ”

"What did he teach you?" Shang Qirui was a little amused and asked casually.

"I taught a set of acupuncture methods to treat the banker's little boy." Doctor Ji had a headache when he thought of this, it was highly poisonous, but Mu Qingge said that it was inconvenient for her to go out, and Doctor Ji was also very helpless.

"Oh? Is he leaving? Shang Qirui wanted to leave, but at this time, his steps were paused and he was a little anxious.

"No, it's not. He said there was something else going on these days. Doctor Ji had no choice but to continue to lie for Mu Qingge.

"Oh." Shang Qirui left slowly, but there was a trace of doubt in his heart, what is the origin of this Qin Ge? At a young age, there are so many things, and their whereabouts are also mysterious.
