The first snow of the ninth year of the Chu calendar came earlier than usual.

The Northern Expedition of the State of Chu encountered some obstacles......

The Yellow River has a small displacement, but the current is turbulent, and the big boats cannot walk, and the small boats are easy to capsize.

Although there are also major wars in the Yellow River Basin, they are not places for water battles, most of them are land battles along the river, and the river itself is more suitable for rushing to cross in narrow places!

After all, Chu's science and technology is "fast", and many aspects are not comprehensive, in terms of the level of military industry, in fact, the airship can be completely pointed.

However, for the Chu State, this piece is still very blank, and it cannot be made in a moment and a half.

Lu Xun was in the Guandu area, and the Wei State was in a stalemate for several months, although there were many small victories, but he was never able to cross the river - even in the artillery era, after the "artillery bombardment" was completed, it was always necessary to "cavalry charge" and "infantry up".

However, across the Yellow River, in a narrow part of the river, artillery bombardment across the bank is no problem.

And the cavalry does not charge and the impact is not great, but the infantry does not ...... If you don't occupy this position, what's the use of just "washing the floor" with artillery?

However, separated by the Yellow River, it was too difficult for the infantry to force it to cross, so the Chu army had all the advantages, but it was never able to cross north.

The Wei army was not given in vain, and many pontoon battles were organized, but they were all resisted by the Wei army.

Since the weather just cooled down in July, some people in the Chu state have already begun to impeach Lu Xun...... Of course, in fact, it is not as serious as "impeachment", but it is recommended that Bai Tu change the commander.

Although it is taboo to change the commander in the battle, but now that Bai Tu is in Xiangyang, he has even decided to set off for Wancheng, which is one step closer to the front line, and when Bai Tu is close enough to the front line, the impact of the natural change of commander will be very small - Bai Tu is the real "coach".

There are also many generals and handsome talents in the Chu State, so there is no need to bet on Lu Xun, but Bai Tu did not accept the suggestion of changing the commander!

The scholars of the Imperial Court, especially Chen Gong, who also took care of the Privy Council, also agreed with Bai Tu.

There is no problem with Lu Xun's strategy and tactics, and the reason why he failed to make contributions quickly is because Lu Xun himself tends to fight steadily, and secondly, because Wei Guocheng is determined to drag ......

After Chen Gong developed the "real-time strategic land reclamation model" with "Ming Strategy", Lu Xun also imitated it in Yizhou.

Lu Xun didn't know how to make a plan, but based on "Heavenly Book Volume III: Feng Shui", he developed his own auxiliary wilderness strategy.

Originally, Lu Su's understanding of "Feng Shui Scroll" was inclined to be strategic and observe the current situation in the world, while Lu Xun was inclined to be tactical, and even developed extreme tactics such as "Absolute Formation".

However, now Lu Xun began to crack the "Feng Shui Scroll" in the second direction, which was close to the direction of his teacher Lu Su, but he was more inclined to observe the influence of the "human heart" on Feng Shui.

When people gather, the qi shifts, the fortune of the dynasty can affect feng shui, and people's hearts can naturally ......

Lu Xun seems to be tepid, but he has been strengthening the influence of Chu and Bai Xue north of the Yellow River, and focusing on attacking the defenders.

Lu Xun, who was once young and vigorous and preferred a stud tactic, was influenced by the overall style of the Chu State and the perennial overseas pioneering, and began to tend to play steadily.

It's just that there are many famous generals and talents in Wei, and at this time, with the Yellow River as a barrier, it is naturally not so easy to break through!

Bai Tuhui heard the criticism of Lu Xun, to a certain extent, because Wei was already in a hurry......

It's not that there are really any senior members of the DPRK who have become the mouthpiece of Wei and are making some counter-plots, but it is true that Wei is deliberately spreading unfavorable news to Lu Xun.

On the other hand, among the courtiers of the Chu State, there are indeed no people who are so brainy as to be optimistic about the Wei State and go undercover for the Wei State, but there are many courtiers who are greedy and jealous of the Lu family!

Therefore, it is normal for some imperial historians who are not good at military affairs to be affected by folk news, or to take the opportunity to pretend to be stupid for other purposes, and try to impeach Lu Xun.

Bai Tu didn't have such a careful thought, but just punished some officials who had nothing to say, talked nonsense and didn't know how to talk nonsense.

Others have some truth, although Bai Tu ignored them, but there was no punishment.

Lu Xun's responsibility as the front-line commander was not moved, and even ...... In September, Bai Tu went north again, led half of the imperial court, and moved to Wancheng!

When he came to Xiangyang from Jinling, although Bai Tu did not build another palace, the entire Chu court basically moved over, leaving only a small number of officials to maintain it in Jinling - not really moving the capital, but preparing to transfer troops first.

And after Lu Xun privately sent a secret letter to Xiangyang, Bai Tu "insisted on going his own way" and moved the center to Wancheng!

In contrast, this decision was more resisted than Lu Xun's front-line command, and many courtiers thought that Bai Tu was in a hurry.

After all, it's already September, is it possible to have a decisive battle with Wei in winter?

Surprisingly, however, the Privy Council and the heads of some confidential departments have gradually supported the resolution......

With such a big movement, Wei Guo naturally would not be completely unaware.

After learning that Bai Tu was going north again, that is, the main force of the Chu army, and the whole was pressed north again, Wei also became nervous, and at the same time, he ...... Cao Cao was nervous, but also with some expectations.

The first snow of the ninth year of the Chu calendar came a little earlier than before...... At the end of September, it snowed for the first time in the Guandu area, and the temperature plummeted!

However, it will be two months before the river freezes and even the horses and soldiers on the river, judging from past experience.

At this time, Lu Xun began to build the obsolete simple white cannon on the other side of the river, and then ...... Every day, a large number of scattered gravel and dead branches are thrown into the river surface, that is, they strive to press down the thin ice floe on the river surface!

When the water freezes, it becomes less dense and can float up – which also ensures that the temperature under the ice is not too low as long as it is deep enough.

It can be said that this is the basis for water to become the "source of life", otherwise if it freezes from below, it will completely freeze once a year, and the current living things will not survive......

It is precisely because the ice can float on the surface of the water and act as a heat preservation, rather than sinking and allowing the water on it to continue to dissipate heat, so it is relatively difficult for water to freeze.

Now Lu Xun is starting from this point to accelerate the freezing of the river!

In addition, the weather was indeed colder this year, and finally in late October, the ice on the river reached the level where it could oversize the troops, and Lu Xun also successfully pushed the battle line to the north of the Yellow River!

In the face of the aggressiveness of the Chu state, the Wei state began to abandon the Yellow River route, perhaps because it felt that it could no longer be held, or perhaps it was ...... It is to want to compete with the Chu State in the Hebei Plain.

Just when the Chu army did begin to affect its morale and combat effectiveness because of the cold, the first batch of cotton clothes in the Chu State was finally in place!

The seeds sent back by Gan Ning the year before last year have already begun to cultivate cotton in many Guantun since last year, and they have been planted in an all-round way this year.

Although there is little response from the people for the time being, and it will take time to popularize it, a large number of officials have ensured the planting area of cotton, and textile machines and the like are ready-made......

When Wei wanted to take advantage of the cold to drag down the "careless" Chu State, the Chu army finally began to distribute cotton clothes......
