C15 (2/2)

Since they had already left the Daizhou realm, even though Zhu Yisu was going to take over, he still had to take the lead to achieve it. Therefore, he wore a set of official clothes, carrying around the body and seals produced by the Ministry of Rites.

He stuck his head out and immediately saw Hee Chong clasping his fists and bowing, ”The summer heat is difficult to resist, Lord Zhu's body is weak and cannot withstand the summer heat. ”Leave this matter to me.”

”Then this old man will be disrespectful.”

There was a reason why Hee Chong wanted to sell himself well. Although his secret service of the Ming Dynasty was glorious, it was extremely difficult for him to rise in rank. Jian Dianbiao had already hinted to Zhu Yisu that this Hee Chong had the intention of hopping off the wall.

In Zhu Yisu's eyes, it was His Majesty who was worried and wanted to place someone from secret service of the Ming Dynasty next to him.

When he heard that Yanmen Gate was about to close, Zhu Hongzhao got curious. He put on a conical bamboo hat and got out of the carriage, and sat with Zhao Qi on the left and right on the front of the carriage.

Yanmen Pass was not a wall blocking the mountain gorge, but rather layer upon layer, relying on the terrain, it was composed of various defensive fortresses, beacon platforms, and defensive walls.

At the entrance, guards from the station were checking the carriages and luggage. They were all wearing mandarin ducks' war coats, holding long spears in their hands and a daggers at their waists. On the wall, large flags, dragon flags, and the flags of the guards and generals were waving in the wind. In addition to the archers standing guard, there were also a few fire blasters set up at the top of the battlements.

”Is secret service of the Ming Dynasty worthy of investigation?”

Most of the people who went in and out of the city were merchants, and in addition to paying the customs fees, they also had to pay tribute to the guarding officers.

Taking out his identity card, Hee Chong was very arrogant.

This attire had always been in line with the secret service of the Ming Dynasty. The surrounding caravans had always been avoiding them, but now that the identity badge was lit up, they had to avoid them as if they were avoiding a tiger.

The gatekeeping officer was a full flag of the seventh rank, so he didn't even dare to fart, much less have a small squad of soldiers under his command.

Zhu Hongzhao watched everything lazily and couldn't help but shake his head with a smile. Just how important was this Swallow Gate trial? It was guarded by a bunch of cowards. The secret service of the Ming Dynasty's reputation was indeed huge. At the very least, one would have to check Hee Chong's identity card 'military registration' and his position and status.

No wonder after a few years, the Jianzhou Jurchens made a detour through defensive loopholes and managed to reach a hinterland like Shandong. When they surrounded the capital's teachers, the surrounding troops had already unleashed their 'Immovable Mountains' spirit of Sun Zijun's tactic to the extreme.

Yanmen Pass is a comprehensive defense system, with defensive walls, garrisons. There were also areas where the families of the army lived, as well as streets dedicated to trade.

After a little replenishment, the convoy left Yanmen Pass and proceeded northwards along the mountain road. They followed the official road and estimated that they would reach the prefectural city of Da Tong as soon as possible.

The mountain road was long and rugged. Zhu Hongzhao observed the terrain along the way and felt a chill in his heart.

Using the cannons of this era to attack Yanmen Pass from the front was a difficult thing. The winding mountain roads, 9 greatly limited the logistics. Moreover, no matter how many soldiers there were, the number of soldiers on the 1st line was limited. The attack power of the soldiers was limited by the terrain.

The cannon's range was not far this year, so it was quite heavy. If he led his troops to attack from the north, it would take some effort to break through Yanmen Pass. His cannons were low down, so they could only be densely packed together due to the terrain. On the other hand, there weren't many cannons shut down at Swallow Gate, but they were scattered around the walls, inside the steep mountain garrison.

Unless their cannons could carry out technological innovations, granular gunpowder? What a joke! 56 years ago, Qi Jiguang's military book had written about the advantages of granule gunpowder and its manufacturing methods. This was a technique that everyone had.

He's in the mechanical department, not the chemical department. He knew how to make nitroglycerin, nitrided cotton. But I do not know the nitric acid, sulfuric acid production process.

Lu Li pondered over the creation of some godly weapon. Zhu Hongzhao didn't know that the serious look on his face, with his head lowered in deep thought, had attracted someone's attention.

Shanxi merchants was a huge system. At this time, the main thing was to operate the tea leaves, followed by silk, porcelain, food and so on. Buying and storing tea from the southern tea producing area 9, high density brick tea is shipped to the north for sale.

The timid ones would sell off their Mashi. If they had the guts, they would go and kill the tiger and sell it in Northern Lu. Usually, the Northern Beings would intercept and kill the scattered caravans, but they would give them a wide berth. This was a relationship left behind by generations of ancestors.

As for the fleeing Horse Bandit, they were even more content with their actions. The so-called family of generals in border army was also fed to the point of being full.

In the afternoon, they met from Yanmen Pass. The team that came along the 1st Road stayed in Shanyin County, Inner Yin-Village. There was a small relay station in the village. From this, one could tell that this place could be considered to be a traffic hub.

Zhu Yisu's status of a thousand households was nothing but trash in the eyes of the relay station's petty official. His Datong Town was one of the most important towns on the 9 sides, the one he did not lack the most was Qiu 8. It was more than eight o'clock, and it was more than nine. If not for their notorious secret service of the Ming Dynasty, how would the relay stations serve them so well, and even slaughter a sheep?

Last year, Saaru was defeated miserably, 5 elite troops were completely wiped out on 4 roads, and 3 generals were killed in battle. In order to replenish the lost command of the border army of the various towns, the Imperial Court had promoted a large number of middle and lower ranking military officers.

This petty official might have treated Zhu Yisu, the thousand man household, as the lucky guy who caught the last bus of the promotion.
