As soon as his voice fell, the rest of the people all looked over.

"This sand map was obviously sent by the local officials. Could it be that there is something wrong with it?" A tanned man with a big chest and a round waist beside Duan Cheng Xuan started cursing.

Gu Danyan raised his eyes to look at him and felt that he seemed somewhat familiar. It was as if he was a martial arts man that came from the countryside after helping Duan Chenxuan with the matter of the Sunset Water Stronghold. If it wasn't for the fact that his elder brother had fought meritorious war and died in battle, he wouldn't have allowed his own younger brother to replace him.

"Is there a problem?" Duan Chengrui asked straightforwardly.

"Of course there's a problem." Gu Danyan lowered his voice, walked to the map in the tent, and pointed to a place with a ravine, "The gully cannot possibly be as deep as you guys are investigating."

"What do you know? Although this chasm is called by that name, it is a bottomless abyss." A high-ranking officer next to him said in a loud voice, "Even the medicinal farmers rarely go there. The surrounding area is filled with cliffs."

The few officers all looked over. Duan Chengrui also found it strange that Gu Danyan was not a local.

However, Gu Danyan just smiled and said, "I indeed don't know how deep this place is, but I can go down there."

After saying that, she returned to Sha Tu's side. She then called for a guard and told him to go to the ditch to check if there were any shrubs or anything, and to retrieve all the herbs nearby.

Two hundred years ago, there was a doctor who accidentally fell into a ditch. He lived in the ditch for more than ten years because he was afraid of being chased. After that, he personally wrote a book called the 'Luochang Book'. Although it is a small book, an old man can come up here. On the other side, he said: "If there really is a road under this ditch, the army will be able to travel less than a hundred miles. If they want to cut off the rations, they will not have to worry about leaving any traces in the snow, and they will also be able to attack unprepared, and they will not need to send any Death Soldiers.

The few officers looked at each other, and Duan Chengxuan sized up Gu Pingyan. He felt it was even more strange and said, "You believed it just because of what happened in that book."

"Of course, but the terrain of this ditch is a little unusual. It seems to have been used as a cemetery a hundred and twenty years ago, and according to the books, the reason why I'm not able to enter this place today is not just because of the steep terrain, but because of the poisonous miasma. If I remove it, I can use tools to transport the food." As Gu Liuyan spoke, someone helped her find a few books.

Gu Danyan looked at them carefully, then raised his head and looked at them, "However, the current situation requires the two halls to come to a decision, so Yun Chen can only do some small things."

After she finished speaking, she went to the side to wait for the soldier's report with Duan Chengrui's approval, and while she did so, she once again sized up the things in her hand.

The generals present were all martial practitioners, and could read a few large characters. They had no idea what kind of book this was.

Duan Chengxuan's gaze only lingered on Gu Danyan for a moment before he continued to talk about the other military affairs. From preparing for battle to training, he needed to prepare food one by one in order to be able to deal with the enemy at any time in the middle of winter.

After waiting for four hours, the two soldiers finally came back with their things. Gu Liuyan did not even listen to the military orders, first the people went to find a pharmacist who knew how to cure the poison, and then she took care of everything in the ditch. She quietly returned to the tent and stood quietly in a corner with some books in her hands.

After the crowd dispersed in twos and threes, Duan Chengrui and Duan Chengxuan had a heated battle of words and words, and he was even more exhausted. However, Gu Mingyan followed the ghosts to practice martial arts every day to sleep in the carriage, looking full of energy and vigor.

Needless to say, Duan Chengxuan would only be slightly exhausted after a few nights.

"Rest early." As Duan Chengrui said this, he even signaled Gu Danyan with his eyes, wanting her to follow him.

"Seeing that you're not tired, come here and take a look at the other terrains. When tomorrow comes around, accompany me to personally see if there's any passage to these two places as well."

"Yes." Gu Danyan couldn't leave even if he wanted to. He could only return to the map with a bitter face.

Duan Chengrui wanted to open his mouth to ask for more, but then he thought for a moment and wondered what he would be noticed by this person, so he could only give up.

There were only two people left in this huge tent. There were soldiers who brought the food for dinner, and two deputy generals were helping out. Gu Daiyan soon began to work seriously.

However, Yun Chen's appearance was quite similar to Gu Pingyan's.

Duan Chengxuan couldn't help being captivated by his gaze. He waited until Su Yuwan had brought in the soup in order to serve the brush and ink before regaining his senses. He raised his hand and pulled Su Yuwan into his embrace, but in the next moment, all of the soup spilled onto his body.

"You! You can't possibly still be alive! " Su Yuwan frantically pointed at Gu Danyan and yelled.

Everyone inside and outside the tent heard Su Yu Wan's scream, but Gu Pingyan calmly put down the book in her hand. She looked strangely at Su Yu Wan, then smiled gently: "I do indeed look somewhat similar to big sister, and even Aunt Zhu said that we are a generation that is rare to have blood ties that are not close to each other, that is fate."

On one hand, the two vice generals understood Yun Chen's appearance. It seemed that this person was really a descendant of the Yun Family.

On the other hand, it was strange that since Yun Chen was a relative of Crown Princess Jing, why would he help the third prince?

"I'm afraid I won't be able to sleep tonight, but I'm not used to the soil and water, and my stomach is always uncomfortable. Could you let me go back and drink some soup?" Gu Daiyan covered his stomach.

Duan Chengxuan lightly pressed down on Su Yu Wan and waved his hand towards her.

When they left, Gu Daiyan's cold eyes fell on Su Yu Wan.

Su Yu Wan immediately widened her eyes. She didn't care that there were still two vice generals present and directly grabbed onto Duan Cheng Xuan's arm. "She's not dead!"

"He's not. He's Yun Chen." This time, Duan Chengxuan directly covered Su Yu Wan's mouth and signaled the two vice generals with his eyes to quickly leave.

After the two vice generals quietly left, Su Yu Wan calmed down a bit, but she definitely wouldn't forget Gu Danyan's gaze: "She is …"

"No." He never believed in the words of a reborn ghost or god. In his entire life, he would never forget the feeling of hugging her cold body in his arms and saying, "He is Yun Chen. When you framed Yan'Er, her little brother came to teach you a lesson."

Suddenly reprimanded, Su Yuwan was stunned for a moment. Then, she looked at Duan Chengxuan in disbelief. "I already know that I was wrong. Big Brother Xuan, I know that it was Yun Chen. I will never mention her again …"

"She's dead." Duan Chengxuan's gaze flickered slightly, but it was unknown if he was telling himself or telling someone else.
