Yang Jing looked at the dark cave behind the stone tablet and for a moment he really didn't know what to do.

Joy, that is definitely the case. The last time the imperial seal was seen in history was when Li Congke, the last emperor of the Later Tang Dynasty, set himself on fire in the Xuanwu Tower, and the imperial seal eventually disappeared. Obviously, this stone tablet carved more than a thousand years ago once again proves that Li Congke did throw himself into the fire holding the imperial seal.

But everyone knows that the Xuanwu Tower of Luoyang Palace in Luojing is made of wood. The temperature of the open flame formed by the wood is only 700 to 800 degrees at most. You should know that the combustion temperature of coal is only about 1,000 degrees, and the combustion temperature of hydrogen is only 1,400 degrees. The imperial seal is made of Lantian jade. The melting point of ordinary jade is more than 1,700 degrees. Even the gold corner of the imperial seal is made of gold, and the melting point of gold is more than 1,000 degrees.

Therefore, the theory that the Seal of the State was burned together with Li Congke is very incorrect. Even if the fire in the Xuanwu Tower was very fierce, at most it would melt the golden corner of the Seal of the State, but it would never melt the main body of the jade seal.

Wood is wood and can never become charcoal. The burning temperature of wood is not that high!

But the imperial seal just disappeared, and it has been missing for thousands of years. During the reign of Emperor Zhezong of the Northern Song Dynasty, a farmer named Duan Yi found the imperial seal while ploughing the field and sent it to the court. After thirteen university scholars conducted extensive research based on the records of the previous dynasty, they determined that it was the imperial seal made by the First Emperor.

But this is probably a lie, or it was simply a play written and directed by Song Zhezong himself. How could the imperial seal fall into the fields of ordinary people? Moreover, when Song Zhezong ascended the throne, it was a full 140 years after Li Congke threw the seal into the fire. How could the imperial seal be left in the fields of ordinary people for more than 100 years without being discovered?

This is pure deception!

Many knowledgeable people in and outside the court of Song Zhezong also suspected that it was a fake, especially in the late Northern Song Dynasty, when Huizong was fond of elegance and added ten seals. People at that time criticized him for adding unnecessary details, but in fact, Huizong seemed to have the deep intention of downplaying the status of the imperial seal.

It is almost certain that the seal of the state was found by someone after Li Congke threw himself into the fire, but it is not known who found the seal of the state.

Now, the answer to this mystery, which can be regarded as the greatest mystery in Chinese history, has finally been revealed. Li Congke did throw the imperial seal into the fire, but he was found by Yue Chengzi, the eunuch of the Later Tang Dynasty, after the fire was extinguished. He was secretly taken out of the Luoyang Palace and finally hid in the cave behind the stone tablet.

Moreover, it is clearly written on the stele that Yue Chengzi met Li Congke after he left for his apprenticeship. No matter when he met Li Congke, it is estimated that Yue Chengzi must have been a man of real ability, otherwise Li Congke would not have invited Yue Chengzi from this remote Taoist temple to Luojing to serve as the Zhongguanzheng of the Sitai after he obtained the throne of the Later Tang Dynasty.

You should know that the Zhongguanzheng of the Sitai is equivalent to an official of the fifth rank. The most important thing is that the Sitai is not under the jurisdiction of anyone except the emperor. It is a unit directly under the jurisdiction of the emperor alone. Therefore, although the Zhongguanzheng has a low official title, he is definitely the emperor's confidant.

This is also the reason why Li Congke called Yue Chengzi to ask about withdrawing troops when Shi Jingtang's troops were at the gates of the city. It was obvious that he valued Yue Chengzi very much.

Moreover, before his death, Li Congke summoned all the ministers. Although Li Congke had been deserted by his friends and relatives and did not have many ministers left at that time, some ministers, including Yue Chengzi, were still given poisoned wine by Li Congke. This clearly showed that Li Congke wanted these trusted ministers to be buried with him.

But this Yue Chengzi was really capable. The poisoned wine did not kill him on the spot. Instead, it allowed him to take advantage of a big opportunity and retrieve Li Congke's imperial seal.

That is to say, the imperial seal, which is said to be as important as the Nine Cauldrons of Yu the Great in Chinese history, is actually hidden in the Heibulun Cave in front of us.

This joy is definitely big enough.

While feeling happy, Yang Jing was also shocked.

This Yue Chengzi is really not a simple character. To be exact, he is definitely a ruthless and cruel guy. If he were to sit in Li Congke's position, Shi Jingtang would probably have no chance.

If nothing else, the fact that he dared to drink the poisoned wine knowing it was poison was enough to prove that Yue Chengzi was cruel. He was cruel not only to others but also to himself. Because Yue Chengzi knew very well that if he didn't drink the poisoned wine, he would definitely be chopped into pieces by Li Congke's guards.

Although the stele only mentioned that one sentence, Yang Jing could imagine the critical situation at that time. Even the emperor was about to throw himself into the fire and burn himself. You ministers, why don't you follow me? Are you staying here to surrender?

Therefore, it is certain that when Li Congke summoned these ministers, he had already made up his mind to kill them. Only after seeing that all the ministers had drunk the poisoned wine would he, the emperor, drag his mother, wife, and son into the fire together.

Yue Chengzi probably saw through the emperor's cruelty. The emperor could even drag his own mother, wife and children into the fire, so what were these ministers? That's why Yue Chengzi drank the poisoned wine.

However, Yue Chengzi was proficient in medicine and had probably prepared an antidote for himself long ago. Although the antidote was not very effective, it ultimately saved Yue Chengzi's life.

Of course, according to Yue Chengzi himself, the antidote was not very effective. At least the residual poison of the poison wine had not been eliminated. Yue Chengzi himself knew that he would not live long, so he put all the imperial seals he had picked up and the things rewarded by the emperor when he was the chief official of the Secretariat into the cave, sealed the door outside the cave, and set up four kinds of traps inside.
