I traveled through the plane space with the trading system

Meng Kexin smiled slightly and replied calmly, "This is a homemade gunpowder bomb, specially used to deal with the enemy."

She secretly felt lucky that she had prepared for this beforehand, otherwise she would have to fight to the death with those Beihan people today.

Ye Muyuan's eyes flashed with admiration. Lei Can excitedly stepped forward and asked curiously, "Miss Meng, how was this gunpowder bomb made? It's so powerful!"

Meng Kexin explained with a smile, "I researched this based on records in ancient books, and it took many experiments before I succeeded."

Meng Kexin changed the subject and looked at Ye Muyuan and asked, "Brother Ye, where are we going next?"

Ye Muyuan smiled and said, "They and I have been here many times. We also have household registration certificates here. After leaving this forest, we will reach Tongzhou, the town closest to Liangzhou City. The people I planted here have a restaurant here. Let's go there now."

Meng Kexin gave Ye Muyuan a big thumbs up and praised him, "Brother Ye, you are so amazing. You even arranged spies here."

Ye Muyuan didn't say anything, but took Meng Kexin and everyone else and rode away on horseback.

The incense filled the building in Tongzhou City, and the guests were all over the place.

In the private room No. 1 on the second floor, Ye Muyuan and Meng Kexin were sitting inside, and the restaurant manager Sun Xudong was kneeling on the ground respectfully.

Sun Xudong is ostensibly in charge of the craftsman camp in Beihan Country, but in reality he is a spy planted here by Ye Muyuan, and Xiangmanlou is his official property.

"Is there something you want to report to me?" Ye Muyuan picked up the teacup and took a sip.

"My lord, I have established a good intelligence network in Tongzhou City according to your instructions. In addition, I have also discovered some important clues about the Beihan Kingdom." Sun Xudong reported with his head down.

"Oh? Tell me about it." Ye Muyuan put down the teacup and looked at Sun Xudong sharply.

"According to the information I received, the Beihan Kingdom seems to be planning a large-scale operation, but the specific details are still unclear. However, I will send more people to investigate this matter as soon as possible." Sun Xudong replied solemnly.

"Very good." Ye Muyuan nodded. "You did a great job. But remember, don't alert the enemy. Also, make sure our identities aren't exposed."

"Yes, I understand." Sun Xudong kowtowed in response.

Ye Muyuan turned to look at Meng Kexin, "Next, we need to be more cautious. Kexin, what do you think?"

Meng Kexin pondered for a moment. "We can use Xiangmanlou as cover to secretly observe the movements of the Beihan Nation. At the same time, I will continue to develop more powerful gunpowder bombs, just in case."

"Okay." A hint of appreciation flashed in Ye Muyuan's eyes. "I'll do as you say."

Ye Muyuan then asked, "How much do you know about the Beihan Nation's Imperial Preceptor?"

Sun Xudong said respectfully, "The Beihan Kingdom's Imperial Preceptor is a legendary figure. Feng Shenlie holds him in high esteem. He suggested digging tunnels. Beihan Kingdom's tunnels can lead to various important cities and serve as secret passages in times of war, allowing for surprise attacks on the enemy."

When everyone heard this, they were all surprised.

Meng Kexin knew clearly that the underground tactic was indeed a strategy of surprise. If successfully implemented, it would definitely cause great trouble to the enemy.

Then Sun Xudong continued to introduce: Once, the national teacher made this suggestion in the hall, and Feng Shenlie appreciated it very much.

"This is a brilliant plan!" said a general, "but digging the tunnel will take a lot of manpower and time, and we must ensure the secrecy and security of the tunnel."

The emperor pondered for a moment and said, "This matter requires careful consideration. Sun Xudong, you must immediately gather the craftsmen and begin planning the route of the tunnel. Ensure that the design is meticulous and ensures its stability and safety."

Sun Xudong took the order and left, and everyone else dispersed and made their own preparations.

In the days that followed, the craftsmen of Beihan worked day and night to dig tunnels, carefully avoiding the enemy's sight while also dealing with various geological challenges.

After months of hard work, the tunnel finally took shape. Feng Shenlie personally came to inspect it and expressed his appreciation for the craftsmen's efforts.

"Keep working hard and make sure to complete the tunnel digging before war breaks out."

The craftsmen were greatly encouraged and worked even harder. They knew that this tunnel would become the secret weapon of the Northern Frost Nation and contribute to the country's victory.

As he spoke, Sun Xudong took out a blueprint and handed it to Ye Muyuan, "Master, this is the distribution map of the tunnels in Beihan Country."

Ye Muyuan took the map and examined it carefully. His eyes followed the lines on the map, as if he were in an intricate underground maze.

It can be clearly seen that with Liangzhou as the center, the tunnel extends in all directions like a huge spider web, leading to various places.

Each tunnel is like a carefully designed passage connecting different cities and regions.

Ye Muyuan couldn't help but sigh: "This is really a huge and complicated project!" He imagined the role of these tunnels in the war and how they provided convenience and support to the army.

Meng Kexin took a look and said, "It seems that my senior is really a talented person. Brother Ye, why don't we go explore this Imperial Master's Mansion tonight."

Ye Muyuan nodded, "That's exactly what I was thinking. This Imperial Master is truly remarkable. If we could recruit him into our team, it would truly be a powerful addition."

Meng Kexin smiled and said, "Brother Ye, you really cherish talent as if it were your life!"

Ye Muyuan smiled but said nothing. He looked at Zan Feng and said, "Stay here tonight. Don't go anywhere without my summons."

"Yes, I obey!"

Meng Kexin said to Meng Fan and Cui'er, "You two should stay here and be on standby at any time."

Cui Er looked at Meng Ke Xin worriedly: "Miss, before leaving, Madam told me to protect you. Please let me go with you."

Meng Kexin glanced at her and said bluntly, "Cui'er, if you stay here, you will be the greatest protection for me."

What I mean is that if you follow me, you will be a drag.

Cui Er understood what her mistress meant and said hesitantly, "Miss, I will stay here. I will definitely practice diligently in the future to improve my strength."

Lei Can saw Cui Er being humiliated, and for some reason he felt uncomfortable. He said to Cui Er, "Cui Er, don't be sad. We will practice martial arts together in the future. Only when you have strength can you protect the master well.

"Okay, I believe you!" Cui'er felt a little better after hearing what Lei Can said.
