As evening approached, Yin dragged his weary body back to the tent. Qingyan had already cried herself to sleep, while Fei Yang sat upright in Yin's study with a stern face, waiting for his return.

On this day, the news that Yin brought back dealt a heavy blow to Fei Yanggu. He never imagined that the Jue Luo clan had completely betrayed the Ulanara clan.

How would Emperor Kangxi deal with Lady Gioro? Fei Yanggu felt even more uncertain, while Qingyan cried loudly, hurt by her mother. No matter how outrageous Lady Gioro's actions were, Qingyan would certainly be the subject of gossip.

Fei Yanggu couldn't help but feel annoyed. His legitimate daughter was the most outstanding. The Jue Luo clan always looked down on their daughters, and even their illegitimate daughter, Xin Ya, received more maternal love than Qing Yan.

"Fourth Uncle, how is Xiao Guai?" Yin noticed that Fei Yanggu's complexion was not good, so he deliberately softened his tone and asked.

Fei Yanggu shook her head. Qingyan was stubborn. Before, she had gone to great lengths to please the Jueluo family, sending them many of Meiai's finest items.

Jue Luo sent many exquisite pieces of jewelry to his maternal family, but in the end, he did not see how the Jue Luo clan helped Xiao Guai.

"Yin, what does His Majesty want to do?" Fei Yanggu shook his head helplessly. He couldn't let his daughter take the blame.

Yin shook his head. His father's face was grim; he probably wouldn't let those two in the capital off the hook...

Fortunately, Fei Yanggu brought Qingyan out with him. If... Jue Luo Shi had any bad temper and pushed Qingyan into a fire pit, he would have been powerless to help.

After an hour of secret investigation between the father-in-law and son-in-law in the study, Fei Yanggu emerged with a relaxed smile on his face. Indeed, cooperating with the Fourth Prince was a wise choice. The Jue Luo clan had already decided on the princes they were loyal to, and he didn't need to force them to change.

Decades later, when the Jue Luo clan has completely fallen into decline, he will lend a helping hand. At the very least, he cannot stand by and watch the descendants of his wife's brother lose their future.

Inside the study, Yin sat in the darkness, lost in thought. Fei Yanggu's words had awakened him; the Jue Luo clan's current allegiance was simply due to their excessive trust in the Crown Prince. In his previous life, Qingyan's relationship with the Jue Luo clan was not good; he was more preoccupied with the struggle for the throne and rarely cared about his wife's family situation.

When he was preparing to seize the throne, the Jue Luo clan had already been suppressed by Kangxi. He tacitly allowed Qingyan to secretly help Fei Yanggu and his two sons to recuperate. On the one hand, he hoped that she could have Fei Yanggu as her father to protect her, and on the other hand, he hoped that Fei Yanggu could live a long life.

Regardless of whether Fei Yanggu held power over the Nine Gates, as long as he remained a pillar of strength, the direct line of the Ulanara clan would not decline. In his previous life, Fei Yanggu was poisoned to death, and until the thirteenth year of the Yongzheng Emperor's reign, he still hadn't been able to find out who had done it.

Now, he is on guard against the person who made the move, and judging by the timing, the poisoning must have happened recently.

Inside the inner chamber, Qingyan rubbed her swollen eyes as she got off the bed. Sulan told her that Yin had kept the study doors closed and hadn't even had dinner.

Her small, flat mouth... perhaps, the affair between Suo'etu and Mingzhu has revealed the princes' private conspiracy; his two eldest brothers are not as loving as they seem on the surface.

"Sisi, may I come in?" Qingyan asked softly as she walked to the door of the study.

"Come in!" Yin Gang tried to stand up, but his body, stiff all afternoon, gave way and his legs went weak.

Su Peisheng followed Qingyan in and lit the candles in the study. She noticed that Yin's expression was not good. She walked over quickly and was pulled to a chair by him. Su Peisheng caught a glimpse of her master's impatient actions out of the corner of her eye, bowed respectfully, and withdrew.

"Fourth Prince, is Mother's matter difficult to handle?" Qingyan was very clever. After noticing Yinbian's expression, she understood that the matter concerning the Jueluo clan was difficult to resolve.

In the afternoon, after Fei Yanggu persuaded her, his expression was not good either. The Jue Luo clan was completely courting death.

Yin looked down into her worried eyes. The Ulanara clan and the Gioro clan were related by marriage. No matter how much filth existed between the two families, the Gioro clan would definitely seek help from Fei Yanggu when something big happened.

etc.....

Yin recalled that in his previous life, Qingyan complained about Guo Luoma's request for Fei Yanggu's help, and after being ruthlessly rejected, Fei Yanggu was soon found to be poisoned.

"Little darling... use your spatial ability to check on Fourth Uncle's health first." Yin used the mysterious spatial ability to ensure that Fei Yanggu's health was good.

Otherwise, Qingyan's support would be much weaker, and Saituo and Eshuo wouldn't be able to suppress Jueluo's underhanded tactics at all. In her previous life, Jueluo had withheld a significant portion of the dowry that Feiyanggu had prepared for Qingyan, causing her to lose face in front of her sisters-in-law.

She stared blankly at Yin. Was there more to the story? Following his instructions, she secretly used her spatial ability to examine Fei Yanggu's body and indeed found a chronic poison within him.

Fortunately, she had given Fei Yanggu an antidote beforehand, making him immune to all poisons, and the toxins were slowly dissipating. At this moment, Yin was very grateful for this blessing from heaven, which saved them a lot of trouble.

"Damn it! Who poisoned them?" Qingyan also examined Eshuo and Saito, and they were also poisoned.

She was about to check on the health of Emperor Kangxi and Consort Tong when she hesitated, worried that the dragon aura emanating from Emperor Kangxi might backfire on her.

Since this concerned everyone's health, she turned the camera directly to the royal tent. The golden five-clawed dragon sensed her goodwill, merely breathed on her, and did not interfere further.

"Fourth Prince, His Majesty and the Empress have both been poisoned to some extent." Yin and her body did not have any poison. "Second Uncle and the others were also slightly poisoned."

Qingyan's answer worried Yin: all the commanders-in-chief who went to war had been poisoned. Who was responsible? The pool of suspects gradually expanded, and even the Mongol princes far away on the frontier were now under Yin's suspicion.

"Mother's health..." Yin was very worried about Consort Tong's health, as she was the weakest among those who had been poisoned.

“The snow lotus powder we gave to the Imperial Concubine before was a holy grail for detoxification. Tomorrow, let’s make some lotus root soup. Everyone can use it for a few days and their health will be much better.” Qingyan thought of a way to detoxify without anyone noticing, but Yin shook his head.

"No, your secret cannot be exposed. We still need the help of the imperial physician. Can the imperial physician detect this poison?" Yin pondered who should take the blame for Qingyan.

Qingyan became confused. Wouldn't it have been better if they had resolved it secretly?

"To be able to poison so secretly, this person must be of extremely high status." Yin thought of the Empress Dowager in the palace. This expedition had severely humiliated the Khorchin, so it was only natural that the Empress Dowager and the Empress Dowager were unhappy.

She gaped in astonishment. It was actually the Empress Dowager who did this?

In Qing Dynasty history, wasn't it said that the Empress Dowager and Emperor Kangxi had a very good relationship?

"Imperial Physician Lan can diagnose it." Qingyan recalled Lan Xi's medical skills. This person came from a family of medical sages and had his own set of skills in detoxification.
