The country asked you to farm, you planted corn cannons

The three of them gathered in the quiet house and discussed the next strategy in a low voice.

Yun Youzi pondered for a moment, then slowly said:

"We have to meet the prince tomorrow, and we have to agree on the terms."

"You can't reveal too much, but you also need to gain the prince's trust."

Zhang Hui nodded in agreement:

"Yes...we have to proceed with caution. After all, we are in a dragon's pond and a tiger's den."

Li Yang thought for a while and said:

"I think we can reveal some information about "Tai Yuan Xuan Zhang" first, but don't be too specific."

"The focus should be on the threat posed by those in black robes and our willingness to assist in the investigation."

Yun Youzi glanced at Li Yang approvingly:

"My little friend is right."

"We need to convince the prince of our value without completely exposing our cards."

Zhang Hui added:

"Also, there is that Li Chengyuan."

"Although he cooperates with us on the surface, who knows what he has in mind..."

The three discussed some more details and finally reached a consensus.

They decided to be cautious when meeting the prince, revealing only necessary information while paying close attention to the movements of all forces in North Korea and China.

Early the next morning, Li Chengyuan arrived as promised and led the three people to the Prince's Mansion.

Along the way, they saw shops on both sides of the street, crowded with pedestrians, and a bustling scene.

However, the three of them were always vigilant, knowing that there might be a turbulent undercurrent beneath this calm appearance.

Arriving in front of the Prince's Mansion, several guards led them into a quiet courtyard.

Not long after, a young man in rich clothes walked into the courtyard. He was the prince of the dynasty.

After seeing his face, Li Yang and Yun Youzi were stunned for a moment.

Then they looked at each other, their eyes conveying something.

This person...

They know each other.

I have officially seen him outside before, the last emperor of the Great Xia Dynasty.

The emperor who sealed the Golden Crow within his own body, but was still unable to protect the peace of the dynasty, eventually turned into a madman...

Xia Yuan.

Li Chengyuan stepped forward to salute, and then introduced the three Yun Youzi to the prince.

Xia Yuan looked at the three of them carefully with his eyes like fire, and finally said:

"I have heard about these three great names for a long time, but when I saw them today, they are indeed extraordinary."

"I wonder if the three of you are willing to serve me, Daxia, and jointly fight against those evil heretics who are ready to move?"

Li Yang paused for a moment, then stepped forward and cupped his hands and replied:

"His Royal Highness the Crown Prince has spoken seriously."

"Although we have some incompetent skills, we are still unable to deal with those guys."

"However, if I can contribute to the imperial court, I will do my best."

Xia Yuan nodded with satisfaction:

"That's good."

"In that case, I'll just tell you."

"The current situation in the DPRK is complicated. My father is old and most of the DPRK affairs are controlled by the Right Prime Minister Zhao Ming."

"However, Zhao Ming has been acting strangely recently. I suspect that he may be colluding with those men in black robes."

When Zhang Hui heard this, he pretended to be surprised and said:

"I didn't expect the situation to be so serious. I wonder if His Highness the Crown Prince has any evidence?"

Xia Yuan shook his head:

"There is no conclusive evidence yet, which is why I need your help."

"Zhao Ming is a cautious person, and it is not easy to find out what he is doing."

Yun Youzi stroked his long beard and asked slowly:

"Then according to His Highness the Crown Prince's opinion, what should we do?"

Xia Yuan pondered for a moment and said:

"Since the three of them are people that Li Chengxin trusts, I naturally don't need to ask anything."

"Let's do this. You will live in the Prince's Mansion as guests first."

"You can freely enter and exit the royal library during the day and consult classics."

"In the evening, we will secretly investigate Zhao Ming's whereabouts...I will arrange manpower to cooperate with you."

The three of them looked at each other and nodded together.

In this way, the three Yun Youzi officially became the guests of the Prince's Mansion.

In the following days, they consulted ancient books in the library during the day, looking for clues about "Taiyuan Xuanzang" and the power of chaos.

At night, he disguised himself and went out of the house to secretly inquire about Zhao Ming's movements.

However, things didn't go as smoothly as they imagined.

Although there are a vast number of classics in the royal library, there are very few records about "Taiyuan Xuanzhang".

Even if they are mentioned, most of them are vague and it is difficult to get useful information from them.

As for Zhao Ming, it was as if he had disappeared from the world.

The spies sent by the prince could hardly get close to the Zhao mansion, let alone find any valuable clues.

But just when the three of them were at a loss what to do, an unexpected opportunity appeared.

That evening, Li Yang was checking classics in the library when he suddenly heard a commotion outside.

He frowned slightly and walked to the window, only to see a group of guards walking into the library surrounded by a middle-aged man in rich clothes.

Li Yang's heart moved, and he followed him cautiously. He saw the man, escorted by several guards, arriving in front of a secret room in the deepest part of the library.

Zhao Ming took out a jade pendant from his arms, flicked it at the door lock, and the door to the secret room opened silently.

Li Yang held his breath and hid behind the bookshelf to observe carefully.

After Zhao Ming entered the secret room, he quickly left in a hurry.

After the others walked away, Li Yang quietly came to the door of the secret room and carefully checked the door lock.

After some exploration, he discovered that there seemed to be another mystery to this lock.

If you can crack it, you may be able to enter the secret room to find out.

Thinking of this, he went back and described his findings to Yun Youzi and Zhang Hui.

After discussion, the three of them decided to sneak into the library tomorrow night at night, try to crack the magic circle, and enter the secret room to check.

The next night, the three of them disguised themselves as watchmen in the library and sneaked into the building quietly.

Arriving in front of the secret room door, Yun Youzi carefully inspected the mechanism, frowned and said:

"This mechanism is very mysterious, and there are even some mysterious principles hidden in it..."

"I'm afraid it will be difficult to crack in a short time."

Zhang Hui seemed a little regretful:

"This is a rare trip, we can't leave empty-handed, right?"

Li Yang pondered for a moment, then slowly spoke:

"I do have a way, but it's a bit risky."

Seeing the questioning looks from the two of them, Li Yang continued:

"I can try to demolish this facility."

"However, this move will definitely leave a lot of traces and cause quite a stir."

After all, this is the library of the capital of Daxia...

If it was intentional damage, it might get them into trouble.

Yun Youzi and Zhang Hui looked at each other and saw the hesitation in the other's eyes.

But in the end, Yun Youzi nodded slightly and said:

"It's God's will that things have come to this."

"My little friend, please be careful. Zhang Hui and I are outside to capture the formation for you."

Li Yang nodded, raised his hand and summoned a large spray mushroom.

Immediately, aiming in the direction of the door lock, wisps of purple spores were sprayed out.

All the spores penetrated into the door lock and completely corroded it in an instant.

The whole time, there was no sound at all.

It's just that this mechanism is completely scrapped.

The next moment, the door to the secret room opened silently.

The three of them looked at each other and quickly entered.

The light in the secret room was dim, with only a few oil lamps emitting a faint light.

The surrounding walls are filled with ancient books, and in the center is a large book table with several ancient books spread out on it.
