"Then Yu'er was poisoned by someone close to him, wasn't he?"

Xiao Lingyu nodded. "The prince is no longer in danger of death. The person behind the scenes already knows about it and will strike again. The prince's body cannot be tortured any further. If he is poisoned again, I will be powerless. We must find this person as soon as possible."

The Empress Dowager's heart, which had just been put at ease, began to rise again. "The poison is colorless and odorless, and it can't be detected with a silver needle. Do you have any solution?"

Xiao Lingyu thought for a moment, "This person can poison food. He must be someone who has access to food all day and is trusted by the prince. The prince was poisoned when he was in Yongcheng. Who was responsible for the prince's food at that time? I will target these people and wait for him to strike again and take him down."

The Empress Dowager frowned. "This method is too risky. He has done this many times, so he must be very skilled and won't be easily exposed."

"Grandmother, according to the normal schedule, we were supposed to arrive in the capital this evening. But we suddenly have to expedite our return. I think the prince's condition has worsened, which is why we are being asked to return quickly."

"The day before yesterday, Yu'er vomited blood and collapsed at the dinner table shortly after lunch. His condition is serious and he may not wake up. The Empress Dowager was so worried that Yu'er would not survive that she sent someone to urge him to leave."

Xiao Lingyu said, "That villain attacked the prince that day with the intention of killing him. He must be among those who touched the prince's food that day."

"Empress Dowager." At this time, Yun Gu spoke up, "On the day the prince vomited blood, guard Xu Moxu put Xiaoyun Pavilion under martial law and brought in everyone who had contact that day for questioning. He knows who was there, but the prince's food was tested and no poison was found. The criminals may have destroyed the evidence."

Xiao Lingyu looked at Yun Gu and asked, "Did the prince eat alone that day?"

"And the princess."

"I'm afraid she's been poisoned too."

The Empress Dowager was horrified. "Will this poison have any effect on the fetus? Wanyi fainted that day!"

As expected, the purpose of letting Xie Wanyi marry in was to make her pregnant with Feng Jinyu's child.

"If you get pregnant and it's not diagnosed, you might die quietly after being poisoned by this."

If Feng Jinyu wants to have another child, it will take at least three to five years for her body to fully recover.

The Queen Mother almost fainted upon hearing this.

"Don't worry, Grandmother. Didn't Sister Wanyi faint that day? If the poison had damaged her body, the imperial doctors would have surely discovered it."

"Those few useless imperial doctors failed to diagnose the true cause of Yu'er's illness. Wanyi's body was damaged by poison, so they certainly couldn't diagnose it..."

Xiao Lingyu complained in his heart: They are all imperial physicians who graduated from professional schools, their medical skills cannot be bad. If I hadn't cheated by using the space laboratory, I wouldn't have been able to detect it.

"...The Empress Dowager has sent someone to call Wanyi over. Please check her pulse."

Xiao Lingyu nodded, and the Empress Dowager sent Yun Gu to invite Xie Wanyi.

"Is this your adopted daughter?" The Queen Mother then looked at Xiao Xier who was sitting obediently beside Xiao Lingyu.

"She is Su Ningxi, my daughter."

Xiao Xier quickly stood up and bowed to the Empress Dowager as a junior, very politely. "Your humble servant, Su Ningxi, pays respects to the Empress Dowager. May the Empress Dowager be blessed with good health."

The Empress Dowager was deeply surprised. This little girl looked like a child from an ordinary family. Where did she pick up Su Xingyi from?

Could it be that the confidence he had to disobey the imperial order was due to his children's family background?

"Quickly, without the formalities, come closer to me."

Xiaoyun Pavilion

"Do you have to fight every day at 9:00 PM?"

"There are still six more rounds to go today. You'll be fine after they're over. Turn your head away quickly and don't peek!" Su Xingyi reached out and pushed his head back.

He can't even know Xiaoyu's secrets, let alone Feng Jinyu.

"Then change positions."

Su Xingyi lifted up his pants. The place where the needle was inserted last night was slightly swollen. "Okay, I'll change the place for you."

Su Xingyi disinfected the area according to Xiao Lingyu's request, then inserted the needle and pushed hard, finishing it in a moment.

Su Xingyi pulled Feng Jinyu's hand over and asked him to press the bleeding wound himself.

He put the syringe into the medicine box, turned around and went to Chaoyang Pavilion to look for Xiao Lingyu and her daughter.

"Brother Su." After two treatments, Feng Jinyu regained the strength to speak, "Am I poisoned?"

Xie Wanyi, who was waiting at the bedroom door, heard the words, gently pushed the door open and walked in.

Li Yuanliang and Xu Mo followed closely behind.

"Prince Shun, we want to know the cause of the illness. If it is really poisoning, we must find the person behind it. Otherwise, he is hiding among us, and the prince will be poisoned again."

Su Xingyi sat down and said, "Brother Yu was indeed poisoned. He was first poisoned in Yongcheng."

Feng Jinyu's heart sank. Sure enough, someone was out to harm him! Needless to say, it was his half-brother.

It’s all for that dragon throne!

"Prince Shun, are you sure he's poisoned?" Li Yuanliang said, a little unconvinced. "Your Highness tests his food with a silver needle every day, and no poison has been found. Furthermore, on the day he vomited blood and fainted, his vomited blood was also tested with a silver needle, and no poison was found either."

"When you were in Yongcheng, you didn't test the food you put into your mouth, did you?"

Li Yuanliang nodded. "Nothing at first. Later, we discovered that the prince had caught a cold and wasn't getting better. After Master Jie arrived, he started vomiting and having diarrhea, so we started testing for poison."

"That's when my brother Jie was poisoned. His old illness suddenly relapsed! He had vomiting and diarrhea, and he was a mess when he got home!"

"How is Brother Jie doing now? Is he okay?" Feng Jinyu was worried. It was he who had implicated Brother Jie.

"Don't worry, Brother Yu, Brother Jie is fine. It's just that the poison is still in his body. We've been keeping a close eye on him, and he hasn't had another attack."

Feng Jinyu asked anxiously, "Why hasn't the poison been removed yet? The poison could take effect at any moment!"

"Your Highness." Xie Wanyi saw Feng Jinyu's unstable mood and quickly comforted her: "Don't worry, the princess will detoxify her, and the child will be fine."

Su Xingyi didn't expect Feng Jinyu to still be so close to Jie Ge'er. "The princess is right. The princess is already preparing an antidote for her to drink. Before this, we never thought that Jie Ge'er's relapse of his old illness could be caused by poisoning. It was only after receiving the imperial edict to return to the capital that the princess and I began to suspect this."

"After all, the princess cured you in the first place and gave you several more prescriptions to prevent your old injuries from recurring. Your old injuries won't relapse easily. The only possibility is that you were poisoned. When we arrived last night, we diagnosed you as if you had been poisoned. The result was just as we suspected, you really were poisoned."

"How did the princess find out that the prince was poisoned?" Li Yuanliang was very curious.

Su Xingyi looked at Feng Jinyu and said, "Brother Yu, the princess taught herself medicine. She has read many medical books and even collected folk medicine books in Huayang County. She knows that some poisons cannot be detected by needles or pulse diagnosis. Once the poison enters the body, the blood will be impure, and blood tests can detect it."
