The new plot of the TV series "The Case of Di Gong of the Tang Dynasty" starring Zhou Yiwei and Wang Likun can be said to be really exciting, in the previous plot, we can see that "* Case" was opened, Lieutenant Envoy Liu and Hou Yu were ordered to come to Penglai County to investigate the Baekje Gold case, and Empress Wu issued a secret decree to let Di Renjie investigate the truth of the ** case, but I didn't expect that there would be a breakthrough point in this case soon. 
With the appearance of the ghost ship, Di Renjie and others found a thin man hidden below the deck on the ship, and after "translation", this thin man confessed everything he saw on the ship, and said that he saw that everyone on the ship was tattooed with black flames, and this black flame undoubtedly became a thorn in the hearts of those who knew it. It wasn't long before the thin man died, he was strangled to death, and the person who gave him so much to eat was none other than Master Yi of the Ship Division. 
It was only not long after that another sailor was brought to Yamen, this sailor's name was Jin Sang, and he claimed that he had been taken down from the ship, and that Wang Lide had killed everyone by himself, and that the whole ship had died, and that his confession and the thin man's confession had the same place, but there were also differences, the difference was that all the sailors did not have tattoos on their bodies, and as for the same, they all said that there was an island on that route. 
Di Renjie and Lieutenant Envoy Liu, Master Yi, Jin Sang, Gu Mengbin and others all went to sea and went to the island, but there was a heavy fog on the sea, and soon Lord Yi was hanged on the mast, followed by Bai Kai to kill Yusu, it turned out that Bai Kai was also from Baekje, with the investigation of the case, Di Renjie had certain clues, but what people didn't expect was that from the preview, Hou Yu, Di Renjie's good brother, directly and without hesitation, ordered Yu Linwei to shoot Di Renjie, which was very surprising, but in fact, this didn't need to be so unexpected, because Hou Yu is this**. 
To be precise, Hou Yue is**case**, that is, Gu Mengbin and the people above Master Yi, so Lord Yi will be killed defenselessly, the reason why Hou Yue is **, the main evidence has two aspects, one is that there are ghosts on the whole ship, it is obvious that it is not Lord Yi nor Gu Mengbin, and Hou Yu's uncle is the secretary of the Criminal Department, and he is a member of the DPRK, so he naturally has the qualifications to participate in this matter and is the backer behind this matter. 
The second and most important point is the "music score", when he was on the boat, Di Renjie wrote to Hong Liang for help, and he asked Hou Yue how he could make a new tune, and at that time Hou Yue said that there was a new tune in the capital, and said that the "music score" was a new way to memorize the score, Di Renjie never forgot it, so Hou Yue directly put away the score and changed the topic, obviously this score is very problematic.
In the later dialogue between Yusu and Cao An, she mentioned one thing, that is, Wang Lide can actually play the piano, and he plays it very well, and he also has a "music score". This should be the biggest secret that Yusu knows about Wang Lide, but she doesn't know that this has anything to do with the case, so she hasn't told Di Renjie about it, and this score is the code for Wang Lide and Hou Yu.
To sum up, Hou Yu is undoubtedly the **case**, and he is Wang Lide's seller, it is he who resells ordnance, obtains Baekje gold from Baekje, and then uses it to buy **, the reason why Hou Yu wants to do this is most likely because it has something to do with "Black Flame", and it is likely that Hou Yu's back is "Black Flame", and it is precisely because of this that he will use this ** case to resell Mo knives and crossbows.
In the preview, although Di Renjie was forced to fall into the sea and disappeared with Cao An, of course they couldn't just die, Di Renjie and Cao An should have been rescued, and they finally arrived on that island and finally succeeded in solving the case.
