Reborn as a doctor, he takes revenge and ruthlessly punishes the scum.

Yu Shuyan smiled faintly and took out a very exquisite hollowed-out glass bottle from her sleeve.

You can vaguely see a beautiful butterfly fluttering its colorful wings.

"This is?"

Gong Qiuyan looked on with curiosity.

Gong Beige snorted coldly:

"Playing tricks, what, you're not going to say that this thing can help you find someone, are you?"

Yu Shuyan looked at Gong Qiuyan:

"Your Highness, this is the 'Tracking Butterfly'!"

"The Tracking Butterfly? Is it the Tracking Butterfly described in ancient books, the one that can track scents?"

Old Qin suddenly spoke up, his voice surprisingly tinged with excitement.

Gong Beige was quite angry that Yu Shuyan dared to ignore her question. At this moment, noticing Qin Lao's unusual behavior, she also frowned and looked at the butterfly fluttering its wings inside the bottle.

Yu Shuyan nodded slightly:

"Old Qin, it is indeed the Tracking Butterfly that can follow scents."

Old Qin's eyes lit up a bit:

"Oh dear~ I don't know, may I ask where Miss Yu obtained this Seeking Butterfly?"

An elderly man following behind Elder Qin, who had clearly rarely seen Elder Qin so emotional, couldn't help but ask:

"Old Qin, is there any story behind this Seeking Butterfly? Why are you so agitated?"

Old Qin looked at the old man and stroked his beard:

“Old Zhou, you don’t know this. Do you know why the Northern Desert Kingdom’s army is often able to discover our deployments when facing our army, causing our army to suffer setbacks in battle?”

Old Zhou paused, then suddenly asked in surprise:

"You don't mean they're relying on this Tracking Butterfly, do you?"

Old Qin nodded with a smile:

"Exactly. So now you know why I'm so excited. The cultivation of the Seeking Butterfly has always been a secret of the Northern Desert Kingdom. It is precisely because of the Seeking Butterfly that the Northern Desert Kingdom, despite having a weaker military than ours, has dared to be our enemy for many years. If—"

At this point, although Old Qin did not continue speaking, everyone understood what he meant.

They all stared intently at Yu Shuyan, and Old Zhou was the first to ask:

"Miss Yu, how did you obtain this Seeking Butterfly?"

Yu Shuyan naturally knew that these elders were truly people who cared deeply about the country and its people. Without keeping them in suspense, she smiled faintly and said:

"I nurtured them."

Yu Shuyan had been pondering how to track down the missing Zhou and Wang. Suddenly, she remembered seeing the Tracking Butterfly when she was testing the mysterious invisibility map. It could find the owner of a scent by following its fragrance, no matter how far away.

She had already cultivated this tracking butterfly according to the guidance of the invisible map.

What we've been waiting for is today.

The excitement in Qin Lao and the others' eyes was palpable.

Mr. Zhou confirmed again:

"Really? I wonder how many of these Tracking Butterflies you can cultivate?"

Yu Shuyan pondered for a moment:

“The breeding of the tracing butterfly is not difficult; the difficulty lies in the medicinal materials needed for its breeding, which are quite rare and scarce. I have only successfully bred this one.”

Old Qin quickly grasped the key point:

"You mean, as long as you have enough medicinal herbs, you can cultivate a continuous stream of Seeking Butterflies?"

Yu Shuyan nodded:

"That makes sense, but medicinal herbs are indeed scarce, and to say they are inexhaustible would be an exaggeration. However, based on my understanding of the medicinal herb reserves in Dayong, with the support of the national strength, cultivating ten or eight a year would not be a problem."

Old Qin was so shocked that he opened his mouth, but couldn't say a word for a moment.

Old Zhou thought he had too few regrets, and unconsciously advised him:

"Ten or eight is quite a lot, so you don't need to be disappointed."

Old Qin suddenly smiled and shook his head:

"I'm not disappointed, I'm happy, very happy!"

Old Zhou was puzzled:

"Happy?"

Old Qin's smile widened even more:

"Yes, I'm so happy, so happy. Do you know how many they can breed in a year with the combined efforts of the entire Northern Desert Kingdom?"

Old Zhou shook his head:

"How many?"

Old Qin laughed even more heartily:

"Not even one a year!"

Disbelief was clearly evident in Old Zhou's eyes:

"Not even one? Although the Northern Desert Kingdom's national strength is not as great as our Great Yong, it's not this far behind. We could get ten or eight with our entire national strength, so how come they can't even get one in a year?"

Old Qin looked at Yu Shuyan:

"That depends on the cultivator's ability!"

Everyone reacted instantly and looked at Yu Shuyan with excitement.

Old Zhou sighed deeply:

“Miss Yu, if you can truly cultivate so many Seeking Butterflies, then your contribution to my Great Yong deserves the worship of all people.”

No one found Zhou Lao's words abrupt.

After all, the role of the Tracking Butterfly is immeasurable in war. Otherwise, the Northern Desert Kingdom would not have dared to burn, kill, plunder, and repeatedly provoke the powerful Dayong Kingdom and the Hanhai Kingdom for so many years.

It can be said that if the Dayong army were to find the trailing butterfly, it would be like adding wings to a tiger.

Don't even mention being afraid of provocations from the Northern Desert and the Vast Ocean; even if the two countries join forces to invade, we can still resist and mediate.

Old Qin bowed deeply to Yu Shuyan:

“Miss Yu, please allow this old man to bow to you on behalf of my people.”

Old Zhou and the others also bowed in response:

"You shall also accept our bow!"

Yu Shuyan was shocked; she truly hadn't expected them to act this way. She quickly stepped aside and curtsied.

"Esteemed elders, you flatter me. Please rise. I am merely..."

"enough!"

Before Yu Shuyan could finish speaking, she was abruptly interrupted by a shrill voice!

Yu Shuyan turned her head and met Gong Beige's eyes, which were so dark they seemed to want to swallow her whole.

Behind Gong Beige, Wen Lang's eyes were also filled with venom, staring intently at her like a wounded viper eyeing its prey.

Yu Shuyan, however, showed no fear whatsoever. She calmly met Gong Beige's gaze, her voice unhurried and measured:

"Your Highness, do you... not believe me?"

Gong Beige sneered:

"Stop bragging~ Anyone can do that. Nobody knows if that thing you're holding is even a Seeking Butterfly. Besides, just because you say you bred it doesn't mean you did!"

As he spoke, he looked at Elder Qin:

"Elders, we must be cautious about such an important matter. We lest we be deceived and make a fool of ourselves."

Not wanting to put the elders in a difficult position, Yu Shuyan smiled.

"Whether it's true or not, we'll find out by trying!"

Gong Beige's gaze grew increasingly cold:

"Yu Shuyan, if you have deceived me and these elders, I will punish you for deceiving the royal family and exterminate your entire family!"

Yu Shuyan's eyes narrowed suddenly as she recalled the scene from her past life where she beheaded the entire Yu family and threw their heads into the icy snow.

His hands at his sides suddenly clenched into fists, but his voice was deep and resonant:

"I certainly won't let Your Highness down!"

Gong Beige, in this life, I will never give you any chance to hurt my family.
