Li Yuan had a lot to do, and he had no clue about it, but Li Yuan understood that even if he had to speed up his preparations, there were some major things that he couldn't rush into, and that things had to be done one by one, and that he had to eat his meals one by one, and that military and political affairs still needed to be carried out in a planned and step-by-step manner, and he must not be thrown into a mess.

The things that need to be done at the moment need to be sequenced, recruit new recruits to reach the full quota, strengthen the training of soldiers and horses, optimize weapons and equipment, optimize the matching of troops, and so on.

The research and development of gunpowder formulas should also be carried out as soon as possible. Li Yuan needs to have his own killer weapon, as a person who has crossed over, Li Yuan can't waste all the means he knows to greatly increase his strength. Those twenty alchemists should immediately use their talents and let them hurry up and plunge into research, if they can really develop this thing, it will be their own killer weapon, which will make Li Yuan feel much more at ease.

All these things were urgent, but Li Yuan had to complete two other things first, one was to take Han Xizai to Xizhou to announce the decree, and the other was to return Li Congjia, the king of Zheng, to the imperial court.

Emperor Li Jing assigned the three prefectures of Dongxi to Wuping, and Li Yuan, as Peng Shiyu's top boss, should lead the Xuanzhi Qincha to personally go to Xizhou to inform Peng Shiyu that the imperial court had approved the request for a seal.

Since Han Xizai has arrived in Langzhou as an angel, this is what Li Yuan wants to do immediately. As for the recruitment training and the gunpowder development of the warlocks, they can only be handed over to the people around them.

However, Li Yuan naturally has people available around him, Liu Jiangsheng once served as the queen of the Wuping army, and accumulated some experience in the matter of recruitment, and the recruitment of soldiers was handed over to Liu Jiangsheng to supervise with full authority, and the training of soldiers did not worry about people to do, and now the generals under his command have, as for the various needs of the warlocks for refining formulas, of course, they relied on the ordnance supervisor Hu Gui to help solve it.

After quickly arranging the affairs of Langzhou, on the first day of October, Li Yuan was escorted by Lin Sichang with 3,000 personal soldiers, and took the angel Han Xizai to embark on the road to the west, and went to the land of Dongxi for the second time, but this time it was not a knife meeting, but a decree.

Interestingly, Li Yuan specially summoned Peng Shigao on the eve of departure, intending to let him return to his hometown in Dongxi, but unexpectedly, this man refused without hesitation, and took the initiative to mention that he was willing to stay under Li Yuan to serve Yunyun.

This made Li Yuan slightly surprised in his heart, but after thinking about it, he suddenly understood, after all, who doesn't want to return to his homeland? In the end, this Peng Shigao still takes into account the love of brothers, and now the eldest brother Peng Shiyu has a foothold that is not stable, and the old thief Tian Hongyou has deliberately released the rumor that Peng Shiyu wants to succeed the second master, Peng Shigao is probably afraid that he will affect Peng Shiyu's rule after going back, so he decided not to return.

However, Li Yuan finally agreed to Peng Shigao's invitation, and he did have the intention of letting Peng Shigao return to Xizhou to balance Peng Shiyu, but now it seems that there is no need for that.

After all, Chenzhou in the three states of Dongxi is actually in his own hands, and recently he has stationed troops and horses on the first line from Linyuan City to Chenzhou, and built beacons along the line, which has firmly held down the barbarians in Xizhou, not to mention that now he can expand the number of troops, and there is really no need to use the old method of driving the tiger and devouring the wolf, and Peng Shigao is a famous tiger general in history, it is the time to use people, why not stay under the account......

Autumn is a crisp day, and the land of Dongxi includes various terrains such as mountains and dense forests, and although the terrain is varied, the only thing that remains constant is the coolness of the weather.

Li Yuan and his entourage crossed the Youshui, under the guidance of the indigenous barbarian guides, ran hundreds of miles every day, entered the mountains and forests, passed by the flat land between the peaks, saw the yellow grass everywhere and the wild flowers everywhere, recalled the previous situation of leading the army to conquer Dongxi, and could not help but feel a little emotional. The scenery is still the same, but the mood is very different.

At the beginning, due to the time limit, it can be said that there were many dangers along the way, but now it is a different relaxed state of mind to revisit the old place.

Now what Li Yuan sees along the way is a scene of peace, which is very different from the situation when he first came here, where war was raging everywhere and everyone was in danger. After trekking all the way, Li Yuan and his entourage finally arrived at Xizhou City seven days later, the land of the former Great War.

Peng Shiyu, who was notified in advance, also led all the civil and military officials to greet each other in Xizhou City, since Li Yuan led the army to pacify Dongxi, helped Peng Shiyu to regain his ancestral business before the snow, and promoted him to the history of Xizhou, this is the first time the two have met again, and congratulated each other.

Peng Shiyu's gratitude is beyond words, Li Yuan can be regarded as his nobleman, if it weren't for Li Dadu's charcoal in the snow, and spared no effort to send troops to Dongxi, now the land under his feet is probably still a traitor, and he has already gone with his grandfather, to some extent, Li Yuan is his savior, not to mention that Li Yuan also guarantees that he is still the assassin of Xizhou.

I haven't seen him for two months, Peng Shiyu has changed a lot, his face is dark and haggard, but he is in good spirits, giving people a sense of rebirth. Although he led the three states of Dongxi to belong to the Tang Dynasty, it was already the best thing for Peng Shiyu to be able to retain his ancestral business.

After the last war, he seems to have become much more mature, and many unrealistic ideas have long been thrown out of the clouds, as if he has become much more pragmatic.

Soldiers and horses were walking in the city of Xizhou, and Li Yuan saw that the city that had been destroyed by himself was being actively rebuilt. Thousands of barbarians are building new houses, building new streets, and a busy scene.

After two months, the devastated landscape of the city was also covered, and nature with its unstoppable power grew new plants and trees from the ruins, erasing the scars of war little by little, and giving the city a new life.

Under Peng Shiyu's arrangement, everyone also went to Huixi Village to see the merit monument erected by Peng Shiyu for the soldiers of the Wuping Army who died in the previous war, which is also a matter that Li Yuan had explained in the past, after all, the death of 8,000 soldiers in the miasma has always made Li Yuan unforgettable. Obviously, Peng Shiyu set up this merit monument in full accordance with the requirements.

Interestingly, Peng Shiyu erected two monuments, one for the fallen soldiers of the Wuping Army, and the other for the fallen soldiers of Dongxi. The two monuments stand side by side on the Huixi village, surrounded by pine trees, very elegant and solemn.

There is an inscription engraved on the bluestone before the two monuments, and the inscription is written by Peng Shiyu himself, which summarizes the war between Dongxi and the Tang Dynasty as a war caused by the rebellion of the rebels, saying that the three states of Dongxi are the territory of the Tang Dynasty, and Li Yuan, the governor of Langzhou, led the army to Fengtian to fight against Yunyun.

This inscription is obviously suspected of whitewashing and flattery, infinitely magnifying Li Yuan's exploits, and at the same time attributing all the casualties caused by the war to the responsibility of the traitors, which are naturally Peng Shiyu's intentions.

However, throwing away some flowery rhetoric, the whole inscription is still positive, expressing regret for this war, regret and mourning for the fallen soldiers on both sides, saying that this is a lesson, and also shows the position of Peng Shiyu himself and the barbarians of Dongxi.

Later, Han Xizai expressed his intentions, and also wrote a memorial to the fallen soldiers on both sides on the spot, which was read by Li Yuan himself, and burned to worship.

At this point, the previous battle in Xizhou can be regarded as a truly successful end.
