These two were spies sent by Xiling. Now there was no grain in the border fortress. If Dongling Emperor sent someone to escort the grain to there, they would snatch it in advance. If it failed, they would destroy it.

This road was the only way from all parts of Dongling to the border fortress. As long as there was any movement, they could know it. Then, they could inform Emperor Xiling to prepare in advance!

The owner weighted the silver in his hands, and a smile appeared at the corner of his mouth.

After Xiling attacked the border fortress, some people asked him to inquire about the suspicious people who went to the border fortress.

Every time he was inquired, those people would give him some money. It was an easy task, so he agreed.

He didn't know what these people were going to do or whom they were going to find. But as long as he had money to earn, he didn't bother to know other things.

Half an hour passed.

Su Tong was a little impatient. He said to Zhao Po, "It's been so long. Why don't we get in the border fortress?"

"Well, let everyone prepare. We'll keep up." Zhao Po nodded at this moment and then said.

After hearing this, Su Tong smiled and said, "Yes!"

With that said, Su Tong walked to the side and said to the people who were resting, "Get up. Hurry up. We're going."

Soon they entered the border fortress.

People on the road to the border fortress came and went in a hurry. Some people walked out of the border fortress with their families and packages on their backs.

It must have been because Dongling was defeated by Xiling before, Xiling would definitely take advantage of the victory to attack again. People living in the border fortress were afraid that Xiling would really break through the fortress. At that time, they would have no way to go, so they were leaving now. In this way, they could survive.

Not long after entering the border fortress, Su Tong pulled the horse's reins and rushed to Zhao Po, "Brother Zhao, is there no water in our water bag?"

"Not much. What's the matter?" Zhao Po glanced at Su Tong and said.

Su Tong pointed to the tea stall in front of them and said, "See. There is a tea stall in front of us. We have been walking for so long. How about sitting down and drinking a bowl of hot tea? Passingly, we can fill the water bag."

"We're going to reach the military camp soon. At that time, we're going..." Before Zhao Po finished speaking, the owner of the tea stall saw them.

The owner hurriedly stopped them, "Young Master, it seems that you have been on the road for a long time. Why not stop to rest and have a cup of tea? The tea is not expensive. A big bowl of tea just needs one copper coin."

"A big bowl of tea just needs one copper coin? Brother Zhao, let's rest here." Su Tong couldn't help but feel a little surprised after hearing this. "In Jing City before, a bowl of tea needed three copper coins." Su Tong looked at Zhao Po and said again.

The stall owner nodded, "If it is not enough, you can add more tea."

"Brother Zhao?" Su Tong then looked at Zhao Po.

Zhao Po hesitated for a while but nodded.

Seeing Zhao Po agree, Su Tong jumped off the horse. He ordered the people behind to park the carriages on the side of the road. Then he ran over and said to Zhao Po with a smile, "Brother Zhao, come down."

Then Zhao Po got off the horse, followed Su Tong to the table, and sat down.

The stall owner hurried over, took the rag off his shoulders, wiped the table, and then said with a smile, "Please wait a moment, Young Masters. The water will be boiled immediately."

"Hey, how much to fill this water bag?" Su Tong handed the water bag to the owner at this time.

The owner took the water bag over and then said with a smile, "Young Master, I will charge you just one copper coin for this water bag."

"You're a kind-hearted person. Thank you." Su Tong looked at the stall owner and praised him.

The stall owner nodded to Su Tong at this time, then smiled, and waved his hand, "You're welcome, Young Master. I set up the tea stall to let passing people rest."

"That's true. Now the border fortress is in chaos, and nobody knows when Xiling will attack again. I saw many people on the way out of the border fortress." Su Tong nodded and said.

The stall owner continued to ask, "You don’t look like businessmen, Young Masters. Now the people in the border fortress are all going to other towns. Where are you going?"

"We are businessmen." Zhao Po, who was on the side, looked at the stall owner and said.

The stall owner nodded at this time, and then said with a smile, "What a coincidence! There is a group of businessmen who passed by not long ago. They came to the border to deliver goods. What do you sell, Young Master?"

"We are selling..." Su Tong blurted out after hearing this.

Zhao Po pulled Su Tong to interrupt him and said, "Is the tea boiled? We are still in a hurry."

"Oh, the water is boiled. Here it comes." The stall owner said with a smile at this time. Then he turned around and walked towards the tea shed.

After the stall owner turned around, Zhao Po looked at Su Tong and said, "Keep quiet about it."

Soon the tea came out.

When they were drinking the tea, the stall owner took the water bag and walked to Su Tong, "Young Master, the water bag is full."

"Well, thanks. Just put it here." Su Tong swallowed the tea in his mouth and said.

The owner nodded and put the water bag on the table.

Zhao Po asked him, "How much is there in total?"

"Young Master, you need to pay ten taels of silver in total, including the water in the water bag." The stall owner said with a smile at this time.

Later, Zhao Po took out ten taels of silver from his pocket and handed it to the owner.

The owner took it with a smile and put it away without counting.

Zhao Po frowned slightly at this time and then asked, "You don't count it?"

"No, the people who pass are all laborious people. I won't say anything if they give me less money. And you don't look like that kind of rascal, Young Master." The stall owner said with a smile at this time.

Zhao Po stood up, tied the water bag to his waist, and then said to Su Tong, "Let's go."

"Okay." Su Tong nodded.

Then he stood up and said to the people sitting next to him, "Everyone has rested, and we will set off now"

"Okay."

"Okay."

"If everything is OK, then let's set off." Su Tong continued to say after listening.

Then they walked to their respective carriages.

Su Tong walked to Zhao Po and said, "It's all fine. Let's go."

They got on their horses and then walked with the team.

As soon as Su Tong left, the stall owner greeted the people at the intersection to come over.

The two came over at this moment and then asked, "Is there anything suspicious?"

"Yes. When I asked what was being transported on the carriages, a person was interrupted by the other next to him. I thought it was suspicious." The stall owner nodded and said.

After hearing this, the two frowned slightly. They glanced at each other and then began to follow in the direction of the carriages.

The carriages had not gone far, and the two soon approached.

Then they watched carefully on the side.

It couldn't recognize what was in the bag from outside. But judging from the rut marks pressed by the carriages, the two thought the goods on the carriages seemed heavy.

Then, one of them took out a dagger from his arms and hid it in his sleeves. He pretended as a pedestrian to approach the carriages. When he passed by, he stretched out his hand and cut the bag on the carriages.

The bag was cut by the dagger, and the potatoes inside rolled out.

When the carriage driver heard something was wrong, he stopped the carriage.

At this moment, Zhao Po saw the carriage stopped, turned his horse around, and asked, "What's the matter?"

"One of the bags in the carriage broke, and the potatoes rolled down." The man driving the carriage got out of the carriage at this time, looked at it, and said to Zhao Po.

Zhao Po frowned slightly when he heard it. He got off his horse to check and saw that the opening in the bag was obviously cut by a sharp weapon.

Then, Zhao Po asked the man who drove the carriage, "Who was passing by the carriage just now?"

"There are so many people here, so I didn't pay attention. What's the matter?" The man who drove the carriage scratched his head and then asked Zhao Po.

Zhao Po shook his head, "It's okay. Hurry up to pack it up."

With that, Zhao Po rode the horse and walked to the front.

Su Tong asked him, "What's wrong?"

"I suspect that someone has got his eyes on us?" Zhao Po pulled the horse's reins, stopped by Su Tong, and whispered.

"What?" Su Tong couldn't help but exclaim.

Zhao Po looked around at this time, and Su Tong understood his meaning. Then, he asked with a look of disbelief, "Someone has got his eyes on us? How is it possible?"

"The back bag is broken." Zhao Po said at this time.

After hearing this, Su Tong couldn't help but breathe a sigh of relief and said with a smile, "Brother Zhao, what can the broken bag mean?"

"I just checked it. It was cut by the knife." Zhao Po continued.

Su Tong frowned slightly at this time and then asked, "Maybe it was cut by passing vehicles or something else."

"In short, we have to move forward quickly and can't delay any longer." Zhao Po said.

Su Tong nodded, and the team continued moving.

The person who cut the bag just now walked to the other person.

"What's inside?" Sun Shang asked Shangguan San at this time.

Shangguan San frowned slightly at this time, "It is not common in Xiling, but I have eaten it."

"What is it?" Sun Shang asked.

Shangguan San said, "Those are potatoes."

"Potatoes? What are those?" Sun Shang then asked.

Shangguan San continued to explain, "It tastes delicious and can make you feel full."

"Then do you think these are sent to the border fortress?" Sun Shang looked at Shangguan San and asked.

Shangguan San's eyes were deep at this time. And then he shook his head, "I'm not sure. The stall owner said that they are trying to cover up something, but these people driving the carriages look like ordinary people."

"Could it be a disguise?" Sun Shang continued.

Shangguan San sighed at this time, then clapped his hands, and said, "Let's catch them first. It won't matter if we catch them wrongly. If we miss, we couldn't explain to His Excellency. Unfortunately, our two lives will be accounted for."

"Well, you follow them, and I will let people come over." Sun Shang said at this time.

Shangguan San nodded, "Hurry up."
