Mr. Zhang carefully opened the ribbon on the box and then lifted the lid. He found that there was an exquisite steam locomotive in the box. To be precise, it should be a model, but the workmanship was extremely exquisite, almost no different from the steam locomotive they rode on before.

"What a delicate car!" The third apprentice quickly picked up the car in the box at this time, but found that the wheels of the car could still turn, which made him scream.

"Let me see!" The second apprentice snatched it at this time, but he felt his hand sinking, and then shouted in surprise, "Master, this thing seems to be copper, after all, iron is not that heavy?"

Mr. Zhang was also afraid that his apprentice would snatch it, so he immediately reached out to take the model of the car and weighed it. He was an old blacksmith. When he weighed the metal material in his hand, he could immediately feel the difference.

"The weight is like copper, but it seems to be heavier!" Old Dad Zhang said, lowering his head and carefully looking at the material of the car. He found that the metal used was white and bright, not like pure copper. So he quickly judged, "There should be something else to this copper, so the color is so white and bright. Only by looking closely can you see a little yellowing."

Mr. Zhang's words also made the three apprentices closer to observe. Sure enough, they found that the material of the car was very unusual, with white light and transparent, looking like silver, but it was brighter than silver, and much harder than silver.

"Master, copper sten is bronze, and this thing weighs like copper. What do you think is added to it?" The eldest disciple who had not spoken before also asked curiously.

"This thing is heavier than copper, which means that the things added inside should be heavier than copper. You can usually see things heavier than copper, that is, silver and gold. This thing looks like silver. Could it be that silver is really added?" Mr. Zhang said this and weighed the weight of the car model again, and found that it weighed at least three or four kilograms.

"Master, if such a heavy thing is really silver, wouldn't it be worth the old nose money?" The third apprentice asked with wide eyes when he heard this.

"Idiot, didn't the master just now? This thing is mainly copper, and there may be silver added to it, not pure silver." The second apprentice slapped the third apprentice and said.

"Copper is also valuable. Such a large piece of copper can be cast a lot of copper coins even if it is melted!" The third apprentice said excitedly again.

"Stern, you really know how to pick up sesame seeds and watermelons. This car is so exquisitely cast. Just for this craftsmanship, it is more valuable than these coppers. What's more, this is the reward given to the master by His Majesty. If it were me, I wouldn't sell it no matter how high the price others paid!" The eldest disciple also smiled at the third disciple at this time.

"That's right. I'll hide this thing behind the ancestor's tablet and use it as our heirloom. From now on, whoever has the best skills of you three will give you this heirloom!" Old Daddy Zhang waved his hand and made a decision.

Mr. Zhang may never dreamed that it was his decision that made the souvenirs for the first trial of the train of the Zhang family's well-preserved train hundreds of years later, and were auctioned for a sky-high price of tens of millions of yuan, becoming one of the highest-priced souvenirs in history.

At the same time, Li Jie also returned home with his souvenirs. The souvenirs for the first flight of the train were actually divided into three levels. The most common one was the train model made of copper and silver alloy, which was mainly distributed to civilians and craftsmen. The better one was the train model cast by copper and gold alloy, such as the one in his hand.

The only one of the highest are the train models made of pure gold, which were only given to Zhu Yunyu and were taken to the palace to collect. Moreover, his professional and professional model not only had the wheels moving, but also had various parts removed. It was simply a miniature steam locomotive. If it weren't for the high cost, Li Jie would also want to build one for himself.

"Dad, what gift have you brought back?" As soon as Li Jie entered the inner house, he saw a terrifying little guy running towards him. It was his son Li Chonghe, nickname Maruko. Behind him, there were two little followers, all of them were girls, one of whom was his and Zhu Yuning's little daughter, and the other was the daughter who had with Zhu Xueqing.

"Forget it, go play with my sister, don't mess it up!" Li Jie threw the gift to his son and said, "There are some fun and toys in the souvenir, just to make a gift for the child."

Maruzi took the gift and shouted excitedly, then ran into it with the gift. The two girls ignored Li Jie and turned around and ran away with Maruzi. While running, they kept shouting "Geeh~Geeh~" and the maid behind them followed closely, for fear that they would fall.

Looking at the three children who ran away, Li Jie couldn't help but smile. As he got married and had children, he felt more and more that he belonged to this era. As for the past life, he regarded it as a relatively long-term dream.

It was already dark. Although Li Jie had already had supper on the train, Zhu Yuning still asked someone to prepare a midnight snack. So when Li Jie returned to the inner house, Zhu Yuning immediately sent someone to send the midnight snack, and then the couple ate and chatted.

"Husband, I've finished the steam locomotive business this time. Can I rest for a while?" Zhu Yuning couldn't help but ask with heartache as he looked at Li Jie's thin face.

During this period, Li Jie had no time to be idle. She had gone to Nanjing to handle the case before, and she encountered an attack on the way back, which made her worry that she could not sleep or eat. She finally returned to the capital and was busy dealing with the steam locomotives. Sometimes she slept on the railway side and did not go home for several days.

"Don't worry, madam, I have nothing else to do after I finish this matter, so I will stay at home with you and never go anywhere!" Li Jie immediately promised that he had indeed neglected to take care of his family during this period. Although he had returned from Nanjing and rested at home for a while, he still could not make up for his debts to Zhu Yuning and the others.

"You said this by your husband, don't go back on your word then!" Zhu Yuning also happily picked up a chopstick for Li Jie. The children at home are still young, especially their young daughter. Because Li Jie is always away from home, the children almost no longer know him, the father.

"By the way, the fourth uncle is delivering a letter today. I'll put the letter in your study. Don't forget to read the letter later." Zhu Yuning suddenly thought of something again, so he reminded him casually.

Although Zhu Di was in Goryeo, he often kept in touch with Li Jie. The letters between the two were very frequent. One letter would be delivered almost ten days and half a month, and occasionally some overseas specialties would be given, so Zhu Yuning got used to it.

Li Jie didn't care either. After dinner, he came to the letter alone. Sure enough, he saw a letter from Zhu Di on the desk. When he opened the letter and took a look, he quickly frowned.
