Traveling through time and space to become a child, supporting the family by catching fish and shrim

Chen Lang's letter was naturally written to Li Xiaohu and his wife, asking them whether they were interested in developing in Linshui. As for the related business in Nanhe County, they could be handed over to Zhao Chunhua's family.

Zhao Chunhua has several brothers.

If the couple is willing to come, let them find Xu Fei and come to Linshui together.

After finishing the letter, Chen Lang took another piece of white paper and wrote down the relevant materials that Xiaoqi needed to purchase.

These materials are used for thermal reactions.

But to be honest, Chen Lang didn't know whether these materials could produce thermal reactions.

He wrote the list of materials entirely based on the little chemistry knowledge he had left in his mind.

Perhaps most of these materials are not used for thermal reactions.

After Xiaoqi left, Chen Lang came to the laboratory and began to rack his brains to think of the chemical formula for the thermal reaction.

"Sodium metal, potassium permanganate, calcium...hiss, what else? Copper? Gold?"

"God, please give me a high school chemistry textbook."

……

In the next few days, apart from accompanying Li Xiuzhi for walks, Chen Lang spent all his time in the laboratory.

Unfortunately, chemistry is a rigorous subject that Chen Lang cannot easily understand. After several days of experiments, none of the thermal reaction experiments were successful.

Just when Chen Lang felt desperate, Xiao Qi's unintentional words made him suddenly realize.

"Sir, I heard that the refugees outside the city dug up an ancient tomb from a previous dynasty, and there are many valuable things inside."

Chen Lang said: "There are also many talented people among the refugees, including tomb raiders."

"Wait...Tomb Raider...Nanpai Third Uncle...Zhang Qiling...Tattoo..."

“This seems to be okay.”

Xiao Qi was stunned: "Sir, who is Zhang Qiling?"

Chen Lang didn't have time to explain and said, "Xiao Qi, go buy some pigeon blood and cinnabar immediately."

"The best ones are white jade pigeons with red eyes... Ask the pigeon seller, they will definitely know."

"Go to the brewery again and bring back a jar of the strongest wine."

"That's all, hurry up."

In the book "Grave Robbers' Chronicles", Zhang Qiling's tattoo will appear when exposed to heat. This is actually a thermal reaction, and tattoos and embroidery have similar functions.

At the same time, Chen Lang also thought of one thing, that is, the Black Miao people in ancient times would tattoo a special tattoo on their children. Once the child's body overheated, the tattoo would appear. This was a method used by the Black Miao people to check whether the child had kala-azar.

The material for this tattoo is pigeon blood and cinnabar.

Of course, both of these things are "anecdotes", and whether they are feasible or not can only be known through experiments.

After Xiaoqi brought back the materials, Chen Lang immediately started the experiment.

Towards evening, Chen Lang walked out of the laboratory laughing.

"It's done! It's done!"

However, before Chen Lang could tell the good news to his whole family, urgent bells and gongs were heard outside the yard.

When the sound became smaller, the whole Linshui County seemed to become much quieter, but an invisible sense of oppression also descended over Linshui.

Then, the faint sounds of noise and chaos began to grow louder.

Chen Lang immediately ran towards the gate of the courtyard.

As soon as the gate of the courtyard was opened, a carriage was seen parked at the gate. Li Xiaohu's family, and Sun Sizhen and her apprentice got off the carriage.

Chen Lang's worry immediately turned into surprise, and he said, "You're here!"

"Hurry, please come to the yard."

"Xiao Qi, ask Ninth Sister to tell Madam that her brother and sister-in-law are here."

"Go to the Duke's Mansion and tell the old lady that Divine Doctor Sun has arrived."

Chen Lang led a few people into the yard and told the maids to make tea.

After not seeing each other for a long time, Li Lanlan not only grew a lot taller, but also felt a sense of unfamiliarity with Chen Lang. She felt a little uneasy sitting on the stool.

Fortunately, Guoguo and Cuicui appeared in time and resolved Li Lanlan's embarrassment.

The little girls held hands and went to play nearby.

At this time, the maids also brought hot tea.

Chen Lang said, "Have a cup of hot tea to relieve your fatigue... Uh, why don't you look so good?"

Li Xiaohu smiled bitterly and said, "Brother-in-law, we were almost stopped outside the city."

Chen Lang said, "Oh, right. I just heard gongs and drums everywhere in the city. What's going on?"

Li Xiaohu said, "There are too many refugees, and the city gates are closed."

"We mentioned your name to the soldiers guarding the city, and they made an exception and let us in."

"But I guess if it's any later, even if I mention your name, brother-in-law, it won't work."

Chen Lang has been busy doing experiments these days and has paid little attention to the outside world.

I didn't expect the refugee crisis to be so serious.

Sun Sizhen sighed, "Although closing the gates can protect the people in the city, what should we do with the people outside the city?"

"Are we going to watch them starve to death outside the city?"

Chen Lang said, "Doctor Sun, don't worry too much. The magistrate of Linshui County, Lord Chang Anmin, is a good official. He will definitely come up with a perfect plan."

Xu Fei said, "Yes, teacher. There are so many people here, we can't save them all. We can only leave it to fate and do our best."

Sun Sizhen nodded slightly and said, "Mr. Chen, you asked us to come in your letter, but you didn't say why. Now that we're here, can you tell us?"

Chen Lang said, "Doctor Sun, please wait a moment. My mother should be the one to talk about this."

Xu Fei knew that Chen Lang had found his biological mother when he came to Linshui last time. He also mentioned it to Sun Sizhen after returning, but Xu Fei did not know the identity of Chen Lang's biological mother.

At this time, Li Xiuzhi came out supported by her ninth sister.

"Xiaohu, Chunhua!" Li Xiuzhi shouted excitedly.

Li Xiaohu hurried over, took Li Xiuzhi's hand, and called out "sister" in a choked voice.

Zhao Chunhua held Erwa in her arms and said with a smile, "Xiaohu was worried all the way, afraid that something would go wrong with you while you were pregnant."

"I told him not to worry, my brother-in-law will take good care of my sister."

"Now I see it, it proves that I was right. My sister is rosy-cheeked and in good health."

Li Xiuzhi pinched Erwa's cheek and said, "The second child has grown so big."

Zhao Chunhua put the second child on the ground and said, "In a few months, I really won't be able to hold him anymore."

"By the way, sister, the second child doesn't have a proper name yet."

"I'll have to trouble my brother-in-law later to pick a name for the second child."

Li Xiuzhi smiled and agreed on Chen Lang's behalf, saying, "Don't worry, if he can't get up properly, I'll strangle him!"

Li Xiaohu said, "Sister, don't stand there. Sit down and take a rest."

Li Xiuzhi said: "No, now is my time to walk, you two can walk with me."

"Mother will be here soon. Erlang and his mother need to talk to Doctor Sun. We shouldn't disturb them."

Zhao Chunhua asked curiously, "Sister, who is my brother-in-law's mother?"

Li Xiuzhi said, "I can't tell you about this matter, and you guys shouldn't ask around."

"Just treat her as an ordinary woman and respect her."
