"Report to General, although this is domineering, it is not easy to poison it. The Qianli Flower among the Nine Flowers has an extremely strong fragrance. It is difficult for the poisoner to hide the fragrance of this flower. These nine flowers and ten insects can be separated, but it cannot last more than three days, otherwise the medicine will fail. It is not easy to calculate the time so accurately." Xu Zhenyu said.

"The emperor has been poisoned for more than half a month, so the source of this poison is impossible to detect," said Heizi.

"Report to the general, it should be like this, but this Qianlixiang has a characteristic. Anyone who has touched this flower will turn green when touching the ruthless flower." Xu Zhenyu said

Xu Zhenyu's words were really bright for them, but where should this ruthless flower be found? Heizi and Sima Xingchen were also in trouble.

"I have never heard of Doctor Xu, this ruthless flower." Heizi said

"Return to the general, I have collected this flower when I was traveling abroad. This flower is beautiful and enchanting, but it contains highly toxic, but it is a good medicine to cure snake venom."

"Okay, this time I can save my life. Doctor Xu is the first to be the master of his achievements. I will reward Doctor Xu well."

"Treat the emperor's illness is the responsibility of me." Xu Zhenyu said

"Does Doctor Xu have ever carved ruthless flowers?" Heizi asked

"Return to the general, never, I will go home and get it." Xu Zhenyu said

"Tianwen, go and escort Doctor Xu home," Sima Xingchen said

"Yes, Emperor" Tianwen and Xu Zhenyu left

"Tianyu will bring all the people who have been to the Palace of Supreme Harmony in the past half month, and wait for Doctor Xu to come back to investigate one by one."

"It's the emperor, Tianyu takes the order," said a man in his twenties.

"Thanks to Doctor Xu this time, brother, how should I reward Doctor Xu?" Sima Xingchen said

"I heard that Doctor Xu's wife died early and only one son is left. Otherwise, you can give him a good marriage." Heizi remembered that Xu Zhenyu had split with his son in his previous life and lived alone to live alone.

"Dr. Xu studied medical skills and neglected management of the backyard. After the matter is over, I will ask my mother to choose a good marriage for him."

About an hour later, Tianwen brought Xu Zhenyu back, "How should Xu Aiqing check it? Just tell them to do it."

"Go back to the emperor, I only need two basins of clear water." The two eunuchs brought two basins of clear water. Xu Zhenyu took out two porcelain bottles from his arms, opened the cap and poured them into two basins of water. He turned around and said to the emperor, "Your Majesty can let your hand be put in the water."

"The person who came asked them to come in and put their hands into the water." Sima Xingchen said

"Wait, it's raining, Tianwen, you guys go and try it first" Heizi said

"General, you don't need these two people," Sima Xingchen said

"Let's check it out to avoid falling into the slaughter of the people," said Heizi.

Tianyu and Tianwen put their hands into the water, but they turned red when they took them out. Sima Xingchen and Heizi's faces changed color. Tianwen and Tianyu were so scared that they knelt down quickly and said, "I didn't poison me."

"You two don't have to worry. This ruthless flower is poisonous and turns red. You can put your hands in another basin of water to retreat." Xu Zhenyu said slowly.

Seeing Xu Zhenyu's slow look, Tianyu and Tianwen both wanted to go up and beat him up.

Tianyu and Tianwen were used by Heizi to protect Sima Xingchen. If something happened to them, it would not be as simple as murdering the emperor, and it would affect the trust between the two.

Trust such things is like a mirror, not whether you laugh in front of it, but whether you will cry in front of it. Feelings are like a big tree, no matter how tall it grows, only how deep its roots are. Only when people trust the most can they have no defense line.

After Tianyu and Tianwen stood up, they reached another basin and reached into another basin. After taking it out, they turned into the original color. At this time, the few people breathed a sigh of relief at the same time.
