Nature's routine is rarely changed by human killings and intrigues.

In the spring of the second year of Taichang, Liaohai froze as usual.

Xu San, the chief shopkeeper of Haoming Trading Company in Liaodong and North China, personally carried a whole shipload of leather goods, deer antler velvets, and mountain delicacies, starting from his father-in-law Mao Wenlong's Phi Island, and traveling south along the coastline to a private port near Shanhaiguan.

According to the network that Zheng Haizhu had laid for him before, Xu San successfully connected with the brother-in-law of the general soldier of Jizhen Juniper, and completed a win-win smuggler transaction.

This means that Zheng Haizhu and Mao Wenlong can each get a few thousand taels of silver, and the Juniper family will earn more after reselling it to a caravan from the south.

After the silver and goods were delivered, Xu San did not socialize with the Du family again, but returned to the southwest corner of Shanhai Town.

There is a small inn funded by a trading company.

Such inns served as contact points for information exchange and personnel in Yanzhou and Tianjin, Xuanfu in Xuanda Town and Fushun in Liaodong Town, Songjiang Port, Dengzhou Port, and Dongjiang Phi Island near North Korea.

At the beginning of last year, after Mrs. Zheng took Xu San through Shanhaiguan, she returned to Beijing and asked Shi Yuelan, the account office, to approve the budget for him, and to build an intelligence network in Shanhai Town.

Today, when Xu San was resting at his inn, the person who should have come entered the door.

"Brother Xu, this is the list of Shanxi businessmen who have come and gone from Shanhai Town since August last year according to the instructions of his wife."

Cheng Xin was in the secret and dim inner room, presenting an envelope.

Xu San took it, and after opening the instructions, he was quite satisfied.

The son-in-law in front of him, who looked like Pan An, had actually only dealt with him twice in Dengzhou and Shanhaiguan, so she determined that the other party was available from the details of her actions.

At the moment, it seems that this kid is indeed very good at his hands and feet, and the information he does is also meticulous.

Like the account book, how much grain and cloth each Jin merchant brought when he went out of the customs, declared the place of going to Liaodong for trading, and did not go to Shanhaiguan when he came back.

When Zheng Haizhu originally ordered these data, Xu San thought about it for a while and understood.

In the scene of Emperor Jianwen's descendants colluding with the Jurchen Tartars, the Fan family, a Jin merchant who had already had an affair with Huang Taiji, was entangled, and any Jin merchants who collaborated with the enemy on the Shanxi side must be more careful, no longer arrogantly go east of the Zhangbei grassland, and transfuse blood and grain products to the Tartars through the Mongolian Horqin tribe that Nurhachi has already married.

These Jin merchants may choose another path of "darkness under the lights", and simply abandon Zhangjiakou on the grounds of fear of raiding by the Tartars and small Mongolian tribes, enter Liao from Shanhaiguan, and say that they will go to Shenyang, Liaoyang, Fushun and other places to do business.

Zheng Haizhu is very satisfied with Xu San's comprehension.

"Xu San, of course, not all traitors in the Jin merchants, such as Chang Gongzi, are not, and there is no need to be. Therefore, you can't kill a large number of rat droppings by mistake for the sake of those three or four rat droppings. Zaohua said that in the past two years, the harvest of the land has become more and more unsuccessful, and there will be a famine in winter and spring. The intelligence points of several traffic arteries, after summarizing the clues, will definitely be able to lock down other traitors on the Zhangjiakou side. ”

At this point, Xu San finally understood the reason why Mrs. Zheng quickly recruited Cheng Xin.

In Cheng Xin's eyes, Xu San is his future.

The little guy who nodded to himself at Dengzhou Port and called him "Chief Master" at the beginning, because he followed Mrs. Zheng, four or five years later, he had become the head of the northern area that overtly and secretly supervised all kinds of important affairs.

Cheng Tax Supervisor, who has rekindled his fighting spirit in life, has the initiative to run errands in full swing, so naturally in addition to the tasks assigned by the leader, he must also give full play to provide more information that his wife will be interested in.

He then whispered to Xu San: "General Du did not treat those Sichuan army guests harshly, and he gave them all winter clothes last year. On the head of March, there was also a brawl disposed of. The military horses of the Sichuan soldiers, under a batch of cubs, a thousand of the local soldiers of Jizhou are about to be occupied, saying that the mare of the Sichuan army eats the grass of Jizhen Town, and the foals raised in Jizhou Town should belong to the Jizhou soldiers. ”

Xu San glared: "What bullshit!" ”

Cheng Xindao: "It's really bullshit, these Jizhou soldiers always feel that they used to bully the Qi family's Zhejiang soldiers in the past." Unexpectedly, after the soldiers on both sides fought, the tooth general sent by Juniper to deal with it directly hit the Jizhou people who led the trouble, and fined them for half a year, telling the two armies that the Sichuan army was going to go out of the fortress to garrison the rebuilt Daning Town, and the outside of the fortress often had to fight in the field, the more horses, the greater the chance of victory, and the Jizhou army bullied the Sichuan army, which was to dig a pit for themselves. ”

Xu San nodded.

The old land of Daning will soon usher in Ma Xianglin. Juniper means that he is actually ready to return the Sichuan army to the old master.

Juniper may not really have a far-sighted vision and treat friendly allies, but he still understands the rules of the rivers and lakes.

Madame had done enough to give the head of the Zhenglan Banner before, and now through the sea sellers, he shared the interests with him, and he put away the arrogance of the warlord of Beiguan.

Xu San listened to Cheng Xin talk about the relationship between the civil and military officials and military generals in this place, and wrote them down one by one, before Cheng Xin was given the salary that the intelligence officers had, and asked him to go back.

Xu San ordered one of his intelligence officers to carry the letter that had been changed to cipher writing and send it to Zheng Haizhu, the master of Beijing.

He himself, loaded the southern goods sent to Shanhaiguan by the Beijing Division, and left a benefit fee according to the valuation of the goods, and after giving them to Juniper's brother-in-law and the officials of the sea patrol respectively, he took the sea order flag like a pass, set sail out of the port, went south to bypass the Port of Lushun, and then turned back to the north and went to the port of Phi Dao.

In this time and space, because Mao Wenlong relied on his military exploits in Fushun, at the suggestion of Zheng Haizhu and with the support of Zhang Chengyin, the general soldier of Liaodong, he passed through Dongjiang Town in advance, so North Korea's Xuanchuan, Yizhou, Tieshan and other places were also ten years ahead of history and became Mao Wenlong's logistics base.

Soon, the land north of Phi Dao, which originally belonged to North Korea, was crowded with Han people in Liaodong Town, either cultivating wasteland or as a middleman for goods from Liaodong, Korea and Japan, while producing grain for the garrison in Dongjiang Town, it also contributed a part of the commercial tax.

Gradually, the fame of the Dongjiang River grew, and Yizhou, which was controlled by Mao Wenlong, began to become a large trade wharf not inferior to Fushun because of its best geographical location, just by the Yalu River, and merchants from all over the world gathered.

The situation that often occurred in the international ports of later generations was not uncommon in Uiju.

Koreans and Japanese who had come across the sea sat opposite each other and made contracts for goods such as Korean ginseng, medicinal herbs, and silver utensils.

Han Chinese and Jurchens, standing side by side, inspect furs, cotton cloth, silk, tea and other goods.

In the war when Toyotomi Hideyoshi invaded Korea more than ten years ago, the merchants will not forget, and the current open hostility between the Jianzhou Jurchens and the Ming Dynasty is even more clear.

However, the exchange of goods and the prosperity of mutual markets are a set of human logic parallel to war.

These ordinary individuals by the Yalu River, at this moment, are more concerned about whether the other party has their own ethnic group or family in their hands and the goods they need.

Xu San waited for Zheng Zhilong's ship at the port of Phi Dao, got the most important things, and then disguised himself as a Korean caravan with his cronies and went north to Uiju.

They will stand guard by the Yalu River until the Mu jujube flowers appear.
