Although Yang Jing already knew the origins of the thirty-six treasures of the ancient spring and the Dongbi sword, he still had to go through some expert research.

Antiques are not antiques just because you say they are antiques. Antiques are about inheritance. An old object with inheritance and an old object without inheritance not only have a big difference in value, but the most important thing is that sometimes if the old object in your hand has no explainable origin, many people will not recognize it!

What do you call an antique that is not recognized? It is a fake!

This is why Yang Jing clearly knew the origins of many old objects through the holy ring, and he could even tell the year in which the original owner made the old object.

But knowing this is far from enough. He needs convincing evidence to prove the origins of these old objects to more people.

"Yes, if we knew it was the work of this prince, then let alone this Dongbi Sword and the Thirty-Six Treasures of Ancient Spring, I wouldn't be surprised even if he came up with something even more sensational!" Cai Yi said with a smile.

Old Liu also nodded and said, "Yes, only the last regent king would be so generous. Tsk tsk, Li Shizhen's Dongbi sword, made of thirty-six ancient coins to make a golden sword. It seems that what is recorded in history books is indeed true. This prince really likes Taoist things."

After a pause, Mr. Liu continued, "If it is really the work of this prince, then the time when these things were buried can also match. During the Xinhai Revolution, this prince was in charge of the military and political power of the world, and the revolutionary army suffered a lot in his hands. The most important thing is that at that time, this prince had a bad relationship with Yuan Datou. Yuan Datou was dismissed and sent back to his hometown by this prince. Later, Yuan Datou took advantage of the momentum of the revolutionary army and forced this prince to resign as regent. It is estimated that this prince was also afraid at the time, so he buried some things. If you count the date, when this prince retired, it was more than a hundred years ago, right?"

Cai Yi nodded and said, "If we follow our inference, it should be like this. But we don't have any definite evidence."

Old Liu smiled and said, "Why is there no definite evidence? Didn't Old Yang say that this Dongbi Sword is the favorite golden sword of that prince, and it is indeed collected by that prince. As long as this is there, the origin of these treasures can be determined."

Cai Yi nodded and stopped talking.

Old Liu turned to Yang Jing and said, "Xiao Yang, what are you going to do with this Dongbi sword and these thirty-six ancient coins?"

Yang Jing smiled and said, "Mr. Liu, didn't we just agree on this? I don't know how to maintain these things, and you are an expert in this area, so you should do your best to help them! I will stay in Yanjing for another week, and during this time, please take care of these treasures. I will listen to the cost. When I return to Tianqu, I am sure that Grandpa Yang will also like to see these well-maintained treasures."

"Haha, Xiao Yang, you have a conscience. Don't worry, the things are with me, and you can't leave them without them. A week is enough for me to take good care of these treasures, and you can come and get them when the time comes. Oh, by the way, remember to remind me to sign an agreement when you leave, so that you won't always worry."

"Look at what you said. How could I not trust you? How could a man of your high moral character and prestige keep such a small thing? Besides, my uncle Cai is here too. If you still let me sign an agreement with you, wouldn't that be a slap in my face?"

Old Liu pointed at Yang Jing and said with a smile: "Don't try to trick me with that. We may be friends, but we still have to abide by the rules. Xiao Zheng, give me that maintenance contract."

"Mr. Liu, this..."

Cai Yi waved his hand at Yang Jing and said, "Listen to Lao Liu. Signing an agreement is good for both parties. We should abide by the rules of the industry. The agreement has been signed, and the amount of money should be paid. Lao Liu, you can't refuse to accept this money."

Yang Jing then nodded silently and stopped talking. Old Liu also pointed at Cai Yi, shook his head, and finally nodded.

As the most powerful museum in China in terms of cultural heritage protection, the Palace Museum not only protects cultural relics within the museum, but also accepts cultural heritage protection commissions from sister units and does cultural heritage protection work for them. Of course, ordinary individuals cannot invite the cultural heritage protection experts of the Palace Museum, but Yang Jing has connections, right? Besides, the things he has produced today are indeed worthy of the personal efforts of cultural heritage experts like Mr. Liu.

Not to mention the Dongbi Sword. The value of the sword itself is not high, but when it involves the Medicine Saint Li Shizhen, the value of this sword immediately skyrocketed countless times, approaching the status of a national treasure.

As for the thirty-six ancient coins, it goes without saying that the sudden appearance of thirty-six ancient coins is extremely rare even in the Palace Museum, not to mention the legendary treasure of the Da Qi Tong Bao.

Just for these treasures, let alone Mr. Liu, even if someone from the museum came, they would definitely decide to take up the commission.

Cultural heritage protection work is not as simple as repairing or maintaining cultural relics. In the process of repairing or maintaining cultural relics, cultural heritage workers can gain a lot of experience. At the same time, they can also carefully study these precious cultural relics and add more content to our country's cultural heritage.

How did China develop over the past 5,000 years? This is not told by words, but by historical books and precious cultural relics.

Why have bronze ware with inscriptions always been a national treasure? It is because the inscriptions on those bronze ware are the inheritance of China's historical culture, which cannot be measured by money!

After handing over these treasures to Old Liu, it was almost five o'clock. Yang Jing said that there was a party tonight, and made an agreement with Old Liu and Cai Yi that when he came to pick up these things, he would treat the two of them and Old Liu's disciples to a good meal. The two elders agreed with a smile.

After coming out of the museum, Yang Jing did not take a taxi. Taking a taxi at this time would only make things uncomfortable for himself. It would be faster to take the subway.

Anyway, the museum is not far from Line 1. After coming out of Xihuamen, you can reach the subway station by strolling along Nanchang Street for a few minutes. After getting on Line 1, whether you transfer to Line 4 from Xidan or Line 10 from Gongzhufen, you can reach the Crowne Plaza Hotel in a very short time.

It was 5:50 when Yang Jing finally arrived at the hotel. When he arrived, Wang Jiazan was talking with the fourth and sixth brothers with two strange pretty girls. The eldest brother was nowhere to be seen, and he probably hadn't come back yet...
