Cheng Qiheng heard this, nodded and said: "That's right, I have also bought a gold object with sulfide attached to it before, using conventional methods, like any acid, alkali, complexing agent can not remove the rust." ”

"Then how did you solve it?" Wang Menghan asked.

Cheng Qiheng smiled: "How else can it be solved, just let it go." ”

Wang Menghan glanced at him: "You won't ask others, or use your brains to check some information?"

Cheng Qiheng smiled and said: "When I was in school, I didn't study chemistry well, and I had a headache when I saw chemistry. The point is that there are not many attachments on that gold object, and it doesn't really have any effect if you put it away, so I didn't get it. ”

"You're just lazy!" Wang Menghan turned his head and asked, "Dad, do you have a way?"

Wang Zhixuan didn't answer, and asked Meng Zitao with a smile: "How do you think it's better to deal with it?"

Meng Zitao thought for a while and said: "I remember that sulfide can oxidize the sulfur ions produced in the dissolution reaction into elemental sulfur when the oxidant is in place, so that the dissolution balance is destroyed. So, if the dissolution reaction continues, will it be possible to finally dissolve all the sulfides on the surface of the gold?"

Cheng Qiheng said a little incredulously: "No, you even know this? Don't tell me, this is also in the information that Zheng Lao gave you." ”

Meng Zitao shook his head: "It's not, it's just that I'm not taking the self-examination now, so I turned over some basic chemistry materials." ”

"Uh......" Everyone then remembered that Meng Zitao had said that he would take the self-examination before, but then there was no movement, and he never heard Meng Zitao mention it, so he forgot about it, but he didn't expect it to be put into practice.

"You're amazing. Cheng Qiheng gave Meng Zitao a thumbs up, and then said: "By the way, I remember that our city's self-examination has already passed the exam in April, and you didn't take the exam?"

Meng Zitao said: "This time I didn't know the bottom of my heart, so I didn't go and reported for July." ”

Cheng Qiheng laughed and said, "Then do you want to wave the flag and shout for you then?"

"Okay, I'm not afraid of being embarrassed anyway. Meng Zitao said with a smile.

Cheng Qiheng touched his nose: "Uh, then I'm really going." ”

Meng Zitao laughed teasingly: "Then go, and no one is stopping you, you must remember to bring a banner then." ”

"That's fine. Cheng Qiheng felt that he had jumped into the pit, and immediately changed the topic: "Let's talk about your golden bowl." ”

Wang Zhixuan laughed and said, "I think Xiao Meng's opinion is very good, you can give it a try." ”

Meng Zitao said: "Uncle Wang, then please do me a favor." ”

Wang Zhixuan said: "Okay, you can go to Shanghai with peace of mind, and I will help you deal with it." ”

Meng Zitao arched his hand with a smile: "Thank you, Uncle Wang." ”

…………

"Zitao, here!"

As soon as Meng Zitao came out of the exit of the train station, he saw Yu Weigang waving to him, and Meng Zitao walked over with a smile.

After getting into the car, Meng Zitao asked, "Shall we go to the hospital now?"

Yu Weigang nodded and said, "Do you want to go to the hotel to settle down first?"

"Okay, buy some gifts by the way. Meng Zitao then asked, "How is the work here?"

Yu Weigang said: "The jewelry store is still in preparation, so the work is like that, basically just need to follow the steps." ”

"No one is stumbling with you, is there?" Meng Zitao asked again.

Yu Weigang laughed: "Villain, there will always be some, but I haven't dared to jump out for the time being." You can rest assured, they are all clowns, and there is nothing to be afraid of. ”

Meng Zitao smiled: "If there is anything you need my help with, just say it." ”

Yu Weigang smiled: "Then I will definitely not be polite." ”

After going to the hotel to put away their luggage and buy gifts, Meng Zitao and the others took the car to the hospital where Mu Yueze was treated.

After asking the location of the nurse's ward, the three of them went to the elevator of the inpatient department to wait for the elevator.

While waiting, a delicate and lovely young woman in her early twenties stood next to them carrying an insulated box.

In the middle of the ring, I saw a middle-aged couple walking over quickly, and the woman scolded the young woman with an annoyed face: "You are really here!"

The young woman looked a little flustered, but immediately calmed down: "Dad, Mom, why are you here?"

The woman said angrily: "You still have the face to ask, we still want to ask you, you don't work hard, why did you come here?"

Seeing that everyone around her looked at her and the others with curious eyes, the young woman felt very ashamed, and said to her parents, "Let's go outside and talk about it!"

"Hmph, it depends on what you say!"

Seeing the family of three leaving, Yu Weigang pushed Meng Zitao with his elbow: "What do you think is going on?"

Meng Zitao said: "Why do you care so much about other people's affairs?"

"Idle is idle, curious. ”

"Okay, the elevator is coming, so don't gossip. ”

"You're boring enough. Yu Weigang and Lao Song followed Meng Zitao into the elevator.

Meng Zitao smiled: "It's not that I'm boring, it's just that you're too gossipy, and you don't know each other, why do you ask so much?"

Yu Weigang said: "So you are too boring, don't you know that gossip can make you happy? I don't believe it, you don't like to listen to gossip." ”

Meng Zitao said: "I also like to listen to gossip, but I am not as interested in gossip as you are. By the way, I didn't think you liked gossip so much, did you?"

"Ding. ”

When the elevator reached the floor, Yu Weigang walked out first: "My life is too boring, and I don't have many friends, so I can only watch some gossip news and entertainment." ”

Meng Zitao said with a smile: "You won't find some hobbies by yourself? For example, piano, chess, calligraphy and painting, cultivate your sentiments, maybe after a while, your wife will be impressed by you." ”

Yu Weigang waved his hand: "Come on, my family's family used to let me learn some vassal and elegant hobbies, but I am not this kind of material." ”

"I don't think you can calm down. Meng Zitao said with a smile: "In this way, I will make you learn the tea ceremony or incense ceremony, which is beneficial to both body and mind, and can also cultivate sentiments." ”

Yu Weigang thought about it for a while, and was a little moved: "These two things are indeed quite suitable, and it is not difficult to learn, are you proficient in them?"

Meng Zitao smiled: "I'm sorry, I'm only a little familiar with these two things, and I'm not proficient in them. ”

Yu Weigang was speechless and said: "Damn, I still want to ask you for advice, but I didn't expect you to understand." ”

Meng Zitao smiled: "I'm not an immortal, I know everything." ”

Yu Weigang said: "Hey, I said that the tea ceremony and the incense ceremony are also very closely related to the antique industry, why aren't you proficient in it?"

Meng Zitao said: "I have a lot of things to learn, and I can't take care of these two for the time being." ”

Yu Weigang was about to make a joke about Meng Zitao, when he heard Meng Zitao point to the door number of the ward and say, "It seems to be here." ”

"Yes, that's it. ”

Since it was an isolation ward, Meng Zitao knocked on the door first, and after a while, a woman who looked a little haggard opened the door, it was Mu Yueze's mother, Zhuang Yedan.

Zhuang Yedan looked a little surprised: "Hey, Xiao Meng, why are you here?"

Meng Zitao said with a smile: "I happened to come to Shanghai to have something, let's take a look at Yue Ze, this is Yue Ze's classmate, Yu Weigang." ”

Yu Weigang smiled and said, "Hello Auntie, I have been to your house before, I don't know if you remember?"

Zhuang Yedan thought for a while and said, "I really can't remember." ”

Meng Zitao said with a smile: "He was only one hundred and forty or fifty catties before, so it's strange that you will remember it." ”

Yu Weigang laughed at himself: "No way, I have eaten too many cakes in the past few years, and I have become like this." ”

Zhuang Yedan smiled and reacted: "Look at me, I'm patronizing and talking to you, come, you come in." ”

Zhuang Yedan invited Meng Zitao and them into the house, and said to Mu Yueze on the hospital bed with a smile: "Yueze, who do you see coming?"

Because of his illness, Mu Yueze was wearing a mask, and when he saw Meng Zitao and them, his expression was very surprised: "Zitao, why are you here?"

Meng Zitao repeated the reason just now, pointed at Yu Weigang and said, "Yue Ze, do you still know him?"

Mu Yueze asked with some confusion: "Are you Yu Weigang?"

"It's down there. Yu Weigang smiled.

"Why haven't you seen you for a few years, you're so fat?" said Mu Yueze.

Yu Weigang smiled: "No way, if you are not careful, you will be so fat." ”

Mu Yueze smiled: "If you hadn't come with Zitao, I might have recognized it right away." ”

The three of them talked about the old for a while, and Mu Yueze thanked: "Zitao, I really thank you for the antiques of my family." ”

Meng Zitao waved his hand: "Yue Ze, this is something I can do, we are both classmates and friends, what is there to thank for, you can recuperate with peace of mind, don't worry about money." ”

Mu Yueze smiled bitterly: "To cure my disease, at least more than one million, do you think I can not worry? The key is to be cured, I can't be like a normal person, I can only do some simple work." ”

For patients with acute leukemia, before the condition is in remission, due to the disease itself or the impact of chemotherapy, the patient's ability to live and work will be greatly affected. At this time, the patient is not fit to work. But when the condition is in complete remission. The patient's body allows, and some work can be considered.

Meng Zitao smiled: "Hey, what do you have to worry about this, with our two bosses here, and you are worried that you can't find a suitable job?"

Yu Weigang patted his chest and promised: "That is, the work is on us, and your main task now is to work with peace of mind." ”

After listening to the words of the two, Mu Yueze asked curiously, "What kind of business are you doing now? Are they all antiques?"

Yu Weigang said: "I am now in the jewelry business, as for Zitao's name, there are many industries, antique shops, auction companies, foundations, and real rooms, or he will have to set up a factory in a short time, there is always a suitable job for you?"

Mu Yueze looked very surprised: "I didn't expect that I haven't seen you for a few years, Zitao, you have actually changed so much." (To be continued.) )
