Yuwen Xiao shrugged helplessly, and looked at Yuwen Xiao who was going crazy with a worried look on his face.

"What can I do? Seeing big brother like this, I am also very sad, but I really can't do anything."

Just like Jiang Shi's reputation as a "straw beauty" and a "sickly child" in the capital of Wanjin Kingdom since childhood, Yuwen Xiao's reputation in Tianqi is similar, with "mediocrity and incompetence" being the most prominent label on him.

Among the many princes of Tianqi Kingdom, the second-ranked Yu Wenxian has the least presence, because his mother, Concubine Hui, his in-laws, and himself are all very mediocre. The only outstanding thing is his handsome face, but there are many princes who are more handsome than him.

But it was such a mediocre and incompetent prince who gained the loyal following of Lin Xiangru, the youngest martial arts champion in Tianqi.

Yuwen Xiao suddenly became a thorn in the eyes of all the princes.

Yuwen Xiao knew that Yuwen Xian brought him to Wanjin State this time without intending to let him return alive and safe.

It was expected that a few people, even a prince, would die when returning from the enemy country.

What's more, he is just a prince with mediocre qualifications. The Emperor Tianqi will not be sad, and the civil and military officials will not feel sorry. They may even take the opportunity to claim compensation from Wan Jin and declare war.

The most ruthless are the imperial family.

Yuwen Xiao is not a fool, he would not let Yuwen Xian plot against him in vain.

He seemed worried, but in fact he looked indifferently at Yu Wenxian who was slashing at people with a sword, with the corners of his lips slightly raised.

"Fairy! I'm going to kill you!" Yu Wenxian suddenly rushed towards Yu Wenxiao with a sword.

Lin Xiangru immediately drew his sword and stood in front of Yuwen Xiao to protect him.

Yu Wenxian's guards immediately shouted, "Lin Xiangru, stop! How dare you draw your sword against His Highness?"

Lin Xiangru said calmly: "I am just protecting the Second Prince."

The guard was just as arrogant and unreasonable as his master: "You can't point a sword at His Highness. If you hurt His Highness, how many lives do you have to atone for your sin?"

Yuwen Xiao patted his chest with a lingering fear and said, "What happened to Big Brother? Why did he suddenly become like a different person? Even I can't recognize him. Is he still my big brother?"

Tianqi's imperial physician sighed, "His Highness is still His Highness, but he was accidentally poisoned and lost consciousness, so he couldn't recognize us."

Yu Wenxiao speculated, "What kind of poison did Big Brother get? How come I've never heard of such a poison that can drive people crazy? He looks more like the reaction to being poisoned in a book."

"Gu?" Tianqi's imperial physician frowned, his expression gloomy. "Your Highness, are you talking about the Gu poison from Miaojiang?"

Yuwen Xiao nodded. "Yes, I've been wandering around the capital of Wanjin these days, and I've heard some news. It seems there are people from Miaojiang in the capital. Could it be that someone from Wanjin wants to murder Big Brother, so they've asked the Miaojiang people to put a curse on him?"

There are books in various countries that record the poison of Miaojiang, but they are not detailed. Even as the imperial physician of Tianqi, he is not sure how the poison of Miaojiang is made and how to detoxify it.

But everyone knows that once you are poisoned by the Miao people, at best you will become a puppet, and at worst you will die without a complete body.

The Tianqi Imperial Physician frowned and said, "But everyone around His Highness is from Tianqi. Even the food is tested for poison with silver needles and by humans before being presented to His Highness. There's no way the Miao or Wanjin people would have a chance to take advantage of it."

Yuwen Xiao said, "But Big Brother still ended up like this. The silver needle didn't detect any poison, and the person who tested it was fine. Doesn't this further prove that Big Brother was poisoned by the Miaojiang Gu poison?"

Tianqi's imperial physician suddenly realized, "Your Highness's words make sense, but this is in the capital of Wanjin. How can we possibly find the person who dared to poison Your Highness?"

"This is what you have to do. I can't do it." Yuwen Xiao spread his hands, looking helpless.

Yu Wenxian was still going crazy, making a mess in the room and even cutting off several people's braids.

Seeing the crown prince in such a state, the Tianqi envoys dared not let him go out and see people. They could only use the excuse that he was seriously injured and unconscious to refuse the visit from Wanjin's officials.

They were busy trying to find a way to appease Yu Wenxian and find him an antidote, so they had no time to continue their plot to frame Jiang Shi.

Yuwen Xiao was not one of Yuwen Xian's men, so naturally they did not tell him about their plan. Therefore, no one cared about him and allowed him to wander around the capital of Wanjin State all day long.

Others didn't know why Yuwen Xianwen went crazy, but Yuwen Xiao knew it clearly, and he even helped.

Although Tianqi and Wanjin were neighboring countries, their capitals were not located in the same place. The capital of Wanjin was in the north, while the capital of Tianqi was in the south. Therefore, everyone from peddlers to nobles loved to eat mushrooms between May and September every year.

There are also mushrooms in Wanjin State, but not many people in the capital like to eat them, so there are not many mushrooms for sale on the market.

Most mushrooms grow in the wild. There are many edible species and many poisonous species.

Silver needles cannot detect the poison of mushrooms.

Therefore, as long as you put a few poisonous mushrooms into a mushroom dish and mix them in, they will not be visible to the naked eye.

The person who tasted the food only had to eat one bite of the non-toxic mushroom, so naturally nothing would happen.

Yu Wenxian had hallucinations because he ate poisonous mushrooms, and saw everyone around him as "toads" or "fairies."

The imperial physician of Tianqi suspected that Yu Wenxian was poisoned by a mushroom, but giving him the antidote did not calm him down, but made him even more manic.

This is because Yuwen Xiao added datura pollen to the amber in the middle of Yuwen Xian's forehead ornament.

Datura flowers are hallucinogenic and poisonous.

Yuwen Xiao asked Yuwen Xian's people to guess that it was poison because he didn't want them to discover that there was datura pollen in the amber of Yuwen Xian's forehead ornament and then become suspicious of him.

The best way is naturally to make them suspect the people of Wanjin State.

But if this continues, there is no guarantee that Yu Wenxian will not wake up one day, and his situation will be very dangerous then.

Between Yuwen Xiao and Yuwen Xian, only one can leave Wanjin State alive and return to Tianqi State.

Yuwen Xiao then thought of cooperating with Jiang Shi.

He naturally didn't believe that the only child of Jiang Chu and Lan Luozhu, the two generals who had defeated their Tianqi Kingdom and almost destroyed the country, would be a sickly and useless child.

The first time he saw Jiang Shi, Yuwen Xiao was sure that this person was extraordinary.

Although he was said to be a sickly person, Jiang Shi had an upright posture, a body as tall as jade, red lips and white teeth, and a more rosy complexion than other young and strong men.

How could such a person be a sickly person? He is clearly a handsome young man.

The enemy of my enemy is my friend.

Yuwen Xian also wants Jiang Shi dead, and even though the two countries are enemies, Yuwen Xiao doesn't think he can't cooperate with Jiang Shi.
