The three imperial doctors got into the car and left.

Leaving Zhao Donglai, Ji Yunchang, and Zhang Dingfeng standing at the door.

Zhao Donglai is nothing, Zhang Dingfeng and Ji Yunchang are very uncomfortable looking at Zhao Donglai and smiling bitterly with some guilt.

"Doctor Zhao, I'm sorry." Zhang Dingfeng said apologetically.

The disdain of the three imperial doctors just now would be unbearable for anyone, let alone the young and vigorous Zhao Donglai.

"To become an imperial doctor, naturally he has his qualifications there, in medicine, I do have a lot to learn, if Mr. Ji is sure that he can let me come to see him, let me know, I will come back then."

Ji Yun often saw that Zhao Donglai was easy to speak, and immediately nodded after being relieved: "Okay, Doctor Zhao, Lao Zhang will arrange food and accommodation for you during this time." ”

Zhao Donglai nodded, and then followed Zhang Dingfeng out.

In Yanjing, it was like going back to his home, Zhang Dingfeng drove Zhao Dong to visit Yanjing, Zhao Donglai has not been here, there seems to be no place to visit, he said to Zhang Dingfeng: "I need to make nine needles with pure gold, I need three sets of different sizes, a total of 27, the density of pinholes is not the same, the specifications are very high, it may cost some money." ”

Zhang Dingfeng nodded: "No problem, then I'll take you to the gold and silver jewelry store to have a look?" ”

Zhao Donglai said: "Do you know anyone?" I want pure gold to be at least 99.9 kind, are you sure about the degree of general jewelry stores? ”

Zhang Dingfeng understood: "I have someone I know, I'll take you there." ”

He directly took Zhao Donglai to a gold and silver jewelry store in the city, and when he saw Zhang Dingfeng's license plate number and others coming down, the store manager came out to greet him personally, and then took him to the VIP area on the second floor.

It didn't take long for the owner of the shop to come over.

"Mr. Zhang, a rare guest."

Zhang Dingfeng said to him bluntly: "I need a material with a pure gold density of 99.9% to make something, do you have it here?" I don't want the stuff in your store, I want to refine the fresh stuff, you know? ”

"Yes, Mr. Zhang, how much do you want?" The shopkeeper asked.

"Not much, less than 300 grams." Zhao Dong said.

"Then Mr. Zhang has to go on a trip in person? A phone call, I'll have someone send it to you, and that's it. The boss smiled.

Zhao Donglai said to him: "Call your technicians, you don't understand some data, I'll tell him." ”

The boss looked at Zhao Donglai: "Who is this?" ”

Mr. Zhang said: "Listen to him, do what he wants, do it." ”

The boss nodded and asked the manager to call the technician in the background.

After the technician came, he stood aside respectfully, and Zhao Donglai had already drawn the data manuscript paper of the thickness, density and slenderness of each of the 27 needles, handed it to him and said, "Can you make it?" ”

After the technician looked at it, he frowned: "Sir, these are smaller than needles, judging from the softness of gold, there is no way to guarantee straightness, and it will bend if you bump it casually, if you have to do it, I suggest adding some copper and iron to ensure its hardness." ”

Zhao Donglai said: "Can you do it?" ”

Technician: "Do it." ”

Zhao Donglai: "That's good, make one and put it on it immediately, remember that I want the purest gold, if it is mixed with a little other ingredients." ”

Zhao Dong came here, looked at Zhang Dingfeng and said, "You came to smash this store." ”

Zhang Dingfeng looked at him very cautiously, and asked curiously, "What will happen if it is mixed?" ”

Zhao Donglai said: "The whole silver needle will penetrate the blood vessels, because gold is the softest metal substance that can pierce the blood vessels of the pores, I just want its softness, once it is mixed, it will pierce the blood vessels, and the consequences are very serious!" I'm not kidding, one doesn't pay attention, do you think about what happens if you heal the brain, a blood vessel ruptures? ”

Zhang Dingfeng swallowed his saliva and understood why Zhao Donglai was so cautious.

He looked at the boss and said solemnly: "I said, I want the kind of gold that is refined with the highest density, you want to get me 300 grams to make these specifications of needles out, and then use high-quality mahogany to package it for me, a density or purity is not enough, I will ask you, you either don't take my list, if you want to take it, I said ugly things in front, mixed with a little water, I let you don't say that in Yanjing, the whole country can't mix!" ”

Seeing Mr. Zhang's serious appearance, the boss became very cautious, he gritted his teeth and said, "Okay, Mr. Zhang, since you are looking for me, I will help you get it, can you give me three days?" ”

Zhang Dingfeng looked at Zhao Donglai and asked, "Is three days enough?" ”

Zhao Donglai glanced at him: "This should be asked to yourself, do you think Lao Chang can let me see it for three days?" ”

Zhang Dingfeng smiled bitterly: "Difficult! ”

Zhao Dong looked at the boss and said, "Then three days." ”

The boss nodded: "Okay, I promise to call Mr. Zhang when I am ready." ”

After Zhang Dingfeng left the gold shop with Zhao Donglai, Zhang Dingfeng asked Zhao Donglai curiously: "Doctor Zhao, I remember that you used to give me silver needles when you gave me needles, why did you turn into gold needles today?" ”

Zhao Dong said: "The density and hardness of silver needles are not good, and most of the other diseases of your kind and ordinary can be used, because it does not involve internal problems in the human body, this time I heard you talk about the old man's situation, I feel that most of them are still in his internal organ problems, this problem is very serious, after all, a handful of old men, an old man can't afford to toss at all, not to mention that the success rate of today's organ replacement surgery is extremely low, I estimate that the old imperial doctors also know this, so I dare not bring it up, who wants to be careless, Protect yourself from ruin! ”

Zhang Dingfeng said: "But I also heard from Chinese medicine people that the tiny needles made of gold can pierce the skin layer of blood vessels?" ”

Zhao Donglai smiled mysteriously: "It depends on who uses it, I think you should come and catch this workmanship yourself, you won't understand how fatal it is for that fragile blood vessel if they are mixed with a little iron or silver to produce too high hardness!" ”

Zhang Dingfeng saw that Zhao Donglai had been admonished twice, and he didn't dare to be careless, after all, the object of treatment was not an ordinary person, so he couldn't be careless.

"If it's okay, send me back to the hotel, and call me again when you can see the old man in the next few days." After Zhao Donglai got out of the car, after saying to Zhang Dingfeng, he turned around and went to a five-star hotel.

On the other side, when Zhang Lan, who had returned to Yanjing, was eating, he saw the grandfather sitting opposite suddenly put down his chopsticks and put them on the table, glaring at Zhang Lan and saying, "What? You say that bastard kid won't come? Does he still want to restore his party membership and position? ”
