Zhong Qinghan sat in his study, looking at the information collected by the Zhong Family's Secret Investigation Division, and constantly analyzing the recent events.

Lian Feng walked in from outside with a teacup, put a cup of fragrant high-grade Yuqian Longjing on Zhong Qinghan's desk, and said softly: "Miss, the tea is ready." ”

"Put it there." Zhong Qinghan didn't raise his head, he kept flipping through the information in his hands, and coughed a few times from time to time.

Seeing this, Lianfeng persuaded him: "Miss, you have been reading the information for more than two hours in a row. I haven't even eaten lunch, why don't you take a break and finish your meal before you continue? ”

Zhong Qinghan tightened her collar, and when it came to the autumn equinox, because of her physique, she was obviously more prone to chills than others. The body was a little weak, and he shook his head with a pale face: "I don't have much appetite, I can't eat, and I'll talk about it when I feel hungry after a while." ”

Lian Feng said worriedly: "Miss, if you continue like this, your body will ......"

Zhong Qinghan smiled freely, "I know my body, even if I eat well and rest well, it is only the past few years." When I was in the school palace, Sun Saijiu once helped me diagnose it, saying that it was difficult for me to live past twenty with this Nine Yin Absolute Vein. I'm nineteen this year, and I'm just over a year away from turning twenty......"

"Miss ......" Lianfeng's eyes were red and her nose was sour, and she wanted to comfort her, but she didn't know how to start.

Sun sacrificial wine is the sacrificial wine that the Jixia School Palace is responsible for teaching medicine, and it is a miraculous medical skill, and it can also be ranked in the top ten in the entire continent. What he says can basically be said to be the final sentence.

If it weren't for that, Zhong Qinghan would not have never returned after returning from the Jixia School Palace. She wants to take advantage of the last few years to spend more time with her family and parents.

Zhong Qinghan raised his eyebrows, his phoenix eyes glared at Lianfeng slightly, and said coldly: "Okay, Lianfeng." It's not a day or two for you to follow me, don't make such a childish gesture to dislike Miss Ben. ”

Lianfeng sucked the upturned Qiong nose, pressed the sadness in his heart, and said a soft "um". Just pay attention, and you can still hear the choked sound in the voice.

"Is there any news about Ji Xiaoxiao that I asked you to check?"

When it came to business, Lian Feng suddenly seemed to be a different person, and said with a serious expression: "Miss Hui's words, although I haven't fully figured out her origin, but according to the results of the current investigation, it seems that her origin is not simple. ”

"This Ji Xiaoxiao appeared in Nuanxiang Pavilion two years ago, and after hearing that he was a criminal official, he was proficient in piano, chess, calligraphy and painting since he was a child, and he was also proficient in singing and dancing. However, the slave maid has investigated the criminal officials surnamed Ji in the imperial court in recent years, but she has not found anyone who matches her identity. ”

Zhong Qinghan said lightly: "In this way, her motive for appearing in the Warm Fragrance Pavilion is very suspicious. By the way, did you find out what she's been doing lately? ”

"This ......" Mercy Feng hesitated for a moment.

"Say!"

"Yes, Miss!" Lian Feng hurriedly said: "The secret investigation department recently found that Ji Xiaoxiao has been in contact with the second son for the past few days, and the two often go in and out together. ”

Zhong Qinghan frowned slightly, and said suspiciously: "You said that Ji Xiaoxiao has been with Midsummer for the past few days?" Isn't she very close to Su Gongzi, how could she be with Xiao Er again, can you find out what they did? ”

Lian Feng lowered his head and said in a lost tone: "Ji Xiaoxiao seems to have someone guarding him, and according to the news reported by the secret investigators, he was almost discovered several times. Due to the identity of the second son, the people of the secret investigation department did not dare to get too close. So ......"

The Secret Investigation Department is a secret agency created by Zhong Gang of Xiliang Gong to collect intelligence, and when it was first established, Zhong Gang had ordered that without his personal order, the Secret Investigation Department was not allowed to investigate anyone related to the Zhong family.

Zhong Qinghan nodded and said, "I know, don't worry about Xiao Er, just keep an eye on Ji Xiaoxiao." I want her every move not to be revealed, and no matter where she goes, she must record them one by one. ”

"Yes, miss, the slave knows. By the way, according to the report of the Black Crow Army spies, Su Gongzi escorted more than 1,000 stones of grain and grass out yesterday, and he had already returned home at noon today. All the grain and grass escorted with him were gone, and when he returned, he brought back a woman. ”

Zhong Qinghan asked with interest: "Oh, it's really interesting to bring a woman back." I wonder what his fiancée will think when she finds out? ”

Lian Feng was surprised: "Miss, didn't you say that Su Gongzi and Zhao Wan'er are just acting?" Why would she have other ideas? ”

Zhong Qinghan took out one from a stack of notes full of dense information, and suddenly smiled: "Don't you know that there are fake dramas in this world?" ”

"According to the report of the Secret Investigation Division, Zhao Chengwen, the owner of the Zhao Firm, has secretly sold many of the properties of the Zhao Firm, or replaced them with properties located in the Jiangnan area. This fully shows that the Zhao firm wants to withdraw from Xining to his hometown, Jiangnan. And in the name of seeking medical treatment, Zhao Chengwen left Xining yesterday, leaving only Zhao Wan'er to preside over business affairs. ”

"I heard that before Zhao Chengwen left, he had met with Su Ziheng, presumably to entrust Zhao Wan'er to him. If Zhao Chengwen's old fox has no intention of making the fake come true, I absolutely don't believe it. ”

Lian Feng echoed on the side: "Su Gongzi has great talents, and it is not surprising that Zhao Chengwen plans to do this. ”

Zhong Qinghan's green jade fingers tapped lightly on the desk, his pretty eyes were half-closed, thinking of a series of things that Su Ziheng had done recently, and sighed secretly in his heart: "If it weren't for his terminal illness, a person like him would not let it go no matter what." ”

"Mercy Feng, tell Tieshan to prepare the car, and we will go to Sujiazhuang."

……

……

As soon as Su Ziheng put down the dishes and chopsticks, Mao Boyi from the workshop rushed over, saying that he had tested several cement formulas and asked Su Ziheng to confirm whether they met the requirements.

For the understanding of cement, no one in the entire workshop is more authoritative than Su Ziheng. Although he didn't know much about this in his previous life, he had seen a lot of it. And the encyclopedia has a lot of information about cement standards, so he is the best person to test the results.

Su Ziheng saw that Zhang Wanqing and Zhang Wanru, who had just confessed their relatives, were fighting hotly, so he temporarily extinguished the matter of arranging for Zhang Wanru to go to Bailu Academy. Let the two sisters spend more time together, anyway, the future will be long.

Just when he went to the workshop, he still had some things to do with Mao Boyi and Zhong Xinde. Cement has been invented, and the rest of the test of high-standard cement only needs to arrange a few people to do the test constantly, and there is no need to take all the craftsmen to do the test, which is too wasteful of manpower.

Su Ziheng's next thought is how to make steel by soil method, reinforced concrete building, how to make cement without steel bars?

And if you want steel bar, the first step is to make steel. Steel is a very important strategic material in his plan. Whether it's crafting weapons or machines, it's indispensable.

In addition, since the furnace has been built, it is a bit wasteful to simply use it to burn cement, and you have to test how to burn glass. If you can make glass, it is a good thing, and if you want to create your own peach blossom source in the future, money is indispensable.

Without a stable source of income, how can you achieve your dreams? It's just that this glass, it's good to study it secretly by yourself, and there is no need to reveal it to the Zhong family.
