Yang Kang didn't know that the ancient people had already understood the chemical knowledge he mastered, although the ancients couldn't tell the reason and didn't understand the principle of chemical reactions, but it did not prevent them from recording this phenomenon and passing it on from generation to generation, which was the accumulated experience.

At this time, Wanyan Honglie, who was far away in Kaifeng City, came with the news, the sixth prince was very angry when he heard the methods of the Great Sect Zhengfu, which had touched his bottom line, if Yang Kang's life experience was exposed, then Bao Xiweak would also be suspected, and Zhao Wangfu would be shrouded in scandal and discredited.

But he can't tell Yang Kang directly, you are not my biological child, leave quickly, it will be too late to be discovered.

"Hurry back!"

This is the message from Wanyan Honglie, concise and to the point, it seems that he didn't say anything, but Yang Kang understands that even if he is speculated for a lifetime, it is better than being confirmed, once it is confirmed, there is no chance of turning the tables, if it is just a guess, as long as Wanyan Honglie finally becomes the emperor of the Dajin Kingdom, those speculations will naturally disappear without a trace.

At the same time, news came from the palace that it was ready, and Yang Kang couldn't leave even if he wanted to.

Two days is a very short time, but it is so long, in these two days, Yang Kang opened his eyes wide, his ears pricked up, and received news from all sides, this time he can only succeed, not fail, if he fails, he will die in the main hall of the palace.

Two days later, the Imperial Palace of the Kingdom of Jin.

Emperor Wan Yan Jing sat high on the dragon chair, looking down at the ministers below, he enjoyed this feeling of control, which is a right that only an emperor can have.

In the past two days, Li Shi'er has been giving him drugs to help him with excitement, which has put Wan Yanjing in a state of excitement, and he feels as if he has returned to his youth, where he can whip and leap horses and pull bows and carvings in the mountains.

There are no foreign ministers in the hall, all the royal relatives who come from the Jin Kingdom, they are very familiar with each other, Yang Kang knows these people very well, he used to memorize the list of these tribes and family members but took a lot of effort, as a royal child, there will always be endless relatives.

Today, these people are just here to see the excitement, and the protagonists are two people kneeling in the main hall, one is the Zongzheng official of the Great Sect Mansion, and the other is the little prince of the Zhao Palace, which can be said to be a life-and-death contest.

If Yang Kang is verified to be not of royal blood, the end will be to be killed on the spot, if it is verified to be royal blood, this Zongzheng official will not only be dismissed, but also may be executed by the angry Wan Yanjing, after all, slandering the royal family is also a big crime.

After bowing to Wan Yan Jing, the two stood up, and the Zongzheng official began to tell the clan relatives the reason for the incident, and gave a detailed account of the investigation results of the Great Zongzheng Mansion, and concluded that Wan Yankang was a child of the Han people of the Southern Song Dynasty, not the blood of the Jin royal family.

This did not cause an uproar among those clan relatives, they had already learned about the cause and effect through various channels, and they just came to see the highlight of this time, which was the blood test.

After the third prince, Yan Hongxi volunteered to do another blood confession with this nephew, he was full of confidence and did not hesitate, which added a lot of points to Yang Kang, and those clan relatives supported Yang Kang in their hearts after seeing Yan Hongxi doing this.

Zong Zhengguan Yīn smiled deeply, and did not stop, or even search Yang Kang's body.

The plan of the crown prince's family is to let Zhao Wangfu and Concubine Yuan perform to their heart's content, and then debunk their yīn scheme, at this moment in front of Emperor Wan Yan Jing, this is a big crime of bullying the king, no one can save them, since this third prince is bent on looking for death, then let him go.

The blood test went very smoothly, and the chamberlain in the palace brought a bowl of water, Yang Kang and Wanyan Hongxi dripped blood into the water at the same time, and the two drops of blood dissolved together in the water, which was a perfect verification that Yang Kang was indeed a royal bloodline.

The royal family began to accuse the Dazong Zhengfu of abusing their power and slandering the children of the royal family at will, Wanyan Hongxi also looked at the officials of the prince's family proudly, but Yang Kang felt that it was very inappropriate, the officials of the prince's family and the Zongzheng official reacted very strangely, they did not panic, but as if they were watching a play.

"Zongzheng, what else do you have to say?" Wan Yan Jing asked in a deep voice.

"Your Majesty, there is something wrong with this water. Zong Zhengguan replied unhurriedly, "Please also ask the imperial doctor to come and check whether there is alum in this water, and you will know it at a check." ”

"Alum stone?" Wan Yan Jing asked.

"As far as the minister knows, the alum stone can be dissolved in the water so that the blood of people who are not close relatives can also be dissolved with each other, if there is alum stone in the water, it is a big crime to deceive the emperor, and the emperor is invited to send the imperial doctor to come to check. Zong Zhengguan explained.

"You're talking nonsense!" King Rong scolded Wanyan Hongxi.

Yuan Concubine Li Shi'er forced her composure, looked at Yang Kang, and was thinking about a way to get out in her heart, she could shift the responsibility to the palace maid who sent water, or she could beg for Yan Jing's forgiveness with years of grace, but that was only an expedient measure, as long as it was confirmed that the child was not of royal blood, Zhao Wangfu and her would be completely finished.

Yang Kang finally understood the problem, he thought that the ancients didn't know the effect of alum, but he didn't expect them to know it for a long time, this is the consequence of not having knowledge, he can be regarded as a cocoon this time.

He knelt on the ground and explained the role of alum to the emperor and the clansmen, and dipped his fingers in the water in the bowl and tasted it, the alum stone tasted sour, and the water had a sour taste after being dissolved in the water, which is the proof.

Wan Yan Jing looked at Yang Kang who was standing below, looked at Li Shi'er beside him, and looked at the royal family relatives, and a sense of anger gathered in his heart, and just when he was about to have a seizure, a voice sounded.

"Grandpa Huang, my grandson has never read a medical book, so naturally he is not better than this imperial doctor, but since it involves his grandson's reputation, I have to reason with this imperial doctor. Yang Kang said calmly, "The imperial doctor said that the blood of anyone who is added to the water can be dissolved, so the grandson and the imperial doctor will try to drop two drops of blood into the water with alum stone to see if they can be dissolved, and then they will know the authenticity of the records in the medical book, or the imperial doctor is telling the truth." ”

"Your Majesty, the ministers don't dare. The Imperial Doctor said respectfully.

"Since it's your idea, why don't you dare?" Yang Kang said lightly, "I also ask the imperial grandfather for permission to take another bowl of the same water, and the grandson and this imperial doctor will know it as soon as they try it." ”

This matter is really full of twists and turns, even Wan Yan Jing can't tell who is telling the truth, but since this kid still wants to try again, then try again.

The water was ready, the imperial doctor confirmed that this was indeed the water with alum stone, in order to show respect, the imperial doctor first dripped his own blood into the bowl, Yang Kang also dripped the blood into the bowl, the imperial doctor's blood began to spread, but Yang Kang's blood has always been in the state of blood beads, and it has not spread.

"You, you used ......," the physician shouted, pointing to the blood beads in the bowl.

At this critical moment, Yang Kang stared at the eyes of the imperial doctor, and he decisively used the soul transfer **, but the imperial doctor practiced the five bird operas handed down by Hua Tuo since he was a child, although he had no internal strength, but his mind was clearer than ordinary people, and it was not easy to control, and he still said a few words under the effect of soul transfer.

Immediately, the imperial physician fell to the ground, and he fainted by the jīng god of soul transfer.

What the doctor wanted to say was that Yang Kang used clear oil, that is, rapeseed oil, Yang Kang applied rapeseed oil to the inside of the clothes, and touched the clothes with his fingers for a while before dripping blood, ensuring that there was a layer of oil on his fingers, and slowly squeezed out the blood beads when dripping blood, and the oil on his fingers was wrapped in the outer layer of the blood beads, which was not easy to spread in the water, even if it was to spread, it would take a while.

If you don't get closer and take a closer look, you can't see a layer of oil flowers near the blood beads, the palace hall is very wide, and the royal family can only see the approximate appearance of two drops of blood.

Yang Kang prepared the clear oil just in case, the court dramas he watched always mentioned alum and clear oil in the section of dripping blood to recognize relatives, alum can make blood dissolve, clear oil can not make blood dissolve, anyway, there is no big mistake in being careful, it is always good to prepare more.

"Grandpa Huang, it seems that the records in the medical books are not accurate, or this imperial doctor deliberately framed his grandson, and asked Grandpa Huang to investigate. Yang Kang knelt on the ground and said sadly. (To be continued.) )
