After Emperor Yang of the Sui Dynasty got the treaty of surrender, he left Liaodong City, turned it into Liaodong County, and immediately asked the servants of Zhongshu Province to write a text, and then sent it to various places, and spread the news of his third imperial expedition and the victory of the final conquest of Goguryeo to all places, and the territory of the Great Sui Dynasty was opened up into the northeast frontier, and the four seas were finally free of hostile forces, and the great cause he had formulated was basically completed.

On the way back, Emperor Yang Guang of the Sui Dynasty felt a little empty in his heart, and the poet's feelings came up, a little sentimental, although the great cause seemed to have been realized, but he did not feel fulfilled and the joy after the war, on the contrary, there was a feeling of unsteadiness in his heart.

On the way to triumph, when passing through the Shanhaiguan area, Yang Guang suddenly sighed, and took the minister of civil and military affairs to Jieshi, which is the shallow water area of the Bohai Sea, the sea water is crystal clear, the water is shallow and the waves are light, the beach is wide and gentle, delicate and mud-free.

A few hundred meters from the shore, there are three huge reefs, about twenty or thirty meters above the sea; Local folklore says that this is the place where Meng Jiangnu is buried in the sea, every time the tide falls, from the shore to the reef looms a huge stone paved plank road in the sea, which can go directly to the foot of the reef.

Throughout the ages, there have been several majestic emperors who have been here, such as Qin Shi Huang, Emperor Wu of the Han Dynasty, and Emperor Wu of Wei "facing the Jieshi in the east to view the sea", and there is a deserted palace site on the river beach, which is the palace built by Qin Shi Huang in the past, trying to wait for the return of the elixir.

Yang Guang felt that his merits were no less than those of these three people, and when he passed through here, he came to stand by the sea, watch the sea, and relieve the depression in his heart.

Yu Shiji stepped forward and asked: "Your Majesty, this time the conquest of Goguryeo and the completion of the expansion of the territory are really a great merit, and they will definitely be passed down in history. ”

Yang Guang sighed lightly: "Stepping to the peak, there is nothing to do, and I have achieved my previous goal, but I have nothing to do." ”

At this moment, Yang Guang has a feeling of loneliness, when some ideals and goals are forcibly realized, he becomes confused and has no goals.

From the beginning of the enthronement, to the great cause of ten years, he did a lot of great things, each of which made the whole country shake, ten years, all completed, with the technical level and labor force at that time, too reluctantly, if Yang Guang can use thirty years to achieve, maybe each can be done well, but unfortunately he seriously shortened the time, too eager for quick success, completed within ten years, as a result, every major project, with millions of bones as the price.

Completed his ideal too quickly, but made him lose the second half of his life, without a goal, and the whole person became confused, as if he had lost his direction all of a sudden.

At this moment, he finally understood why wise people such as Emperor Qin and Han Wu wanted to send people to find the elixir of life later, because after the royal power in the world reached its peak, these people's minds were no longer in the world, but longed to become immortals, pinning their goals on the ethereal immortal stream, and finding a direction for themselves, otherwise, the big people and great men who lacked goals and ideals would have nothing to toss, and they would be uncomfortable and lack a sense of existence.

Yu Shiji proposed: "Your Majesty has completed such a feat, you should follow the example of the ancient sage, inspect the Quartet, and let the people everywhere admire Your Majesty's dragon power. ”

After hearing this, Yang Guang's heart moved, and he reluctantly lifted his spirit, and suddenly felt that it was necessary to tour the grassland tribes in the north, because for the first crusade against Liaodong, many grassland tribe chiefs accompanied him, but they saw him defeated and fled, suffering heavy losses, and he was very faceless. This time he finally conquered Goguryeo, and when he went to the steppe, he summoned those unruly tribal chiefs and gave them a dismount to save the face they had lost.

"This is a very good proposal, I want to go out of the northern tour!" Yang Guang decided, asked the ministers to discuss the route, and finally decided to go to Fenyang Palace first, and then go out of Yanmen Pass to patrol the fortress.

The hundreds of thousands of troops here are not needed at all, and if they accompany them, the transportation of grain and grass is too troublesome, so they only take the Praetorian Guard and the Xiaoguo Army to go, and the rest of the government soldiers go back to their places to defend and suppress the rebel team.

Soon put into action, the army was mighty, from Yuyang County all the way to the west, through Zhuo County, to Yanmen County Fenyang Palace.

At this time, it was the end of July, the heat was scorching, the marching speed was not fast, there was no tension of going to the battlefield to fight, and the ministers and the beauties of the harem were in a better mood.

Luo Zhaoyun has already returned to the northwest of Zhuo County, here, the intelligence organization is covered, and half of the economic lifelines of the counties are secretly in his hands, well-informed, after learning the news that the three expeditions to Goguryeo have been successful and have toured Yanmen in the north, he sighed lightly, the historical time has advanced, next, will there be a siege of Yanmen?

During this period of time, he integrated resources, and he was involved behind the scenes in the operation of the four gates, and he was more concerned about the manufacture of weapons, and he wanted to create high-quality weapons, and at the same time, he was also preparing to secretly develop black powder.

Luo Zhaoyun was very interested in flames, but in this Sui and Tang dynasties, it was obvious that black powder had not yet been fully formed and developed, let alone applied to war, he privately asked some skilled craftsmen, and learned that there were indeed gunpowder craftsmen in the people, but the purpose was to make fireworks and firecrackers, which were used in festivals or circus performances.

He stared at Xiao Yiyi and sent people to look for this kind of gunpowder craftsman everywhere, and he wanted to bring them all back to Zhuo County and put them together to develop black powder.

Although he knew that through the knowledge of later generations, he roughly knew the relatively standard ratio of the three basic components of black powder, but how to solve the purification of nitrate in gunpowder production, the purification of sulfur, etc., did not know anything, and the manufacturing process of uniform gunpowder particles was not clear.

Ignoring Yang Guang's northern tour for the time being, Luo Zhaoyun is bent on developing his own power, and he has a premonition that the day when the world will compete for power is coming soon.
