Judging from the situation where * Dragon Soul was passed, Yang Rui still underestimated the impact of the severe winter on marching and fighting. Although the previous battle of Guandu, the Huojiahui League all over the country flocked forward, it was teleported through the plot. .

After that, all the princes basically stayed on the back of the Yellow River, and all parties had to make do with the support of food, grass and other materials, so basically no more marches were carried out. At most, they would just run a distance along the Yellow River.

Of course, the princes of the Huojiahui League were defeated and were not included when they ran away. There was no way to do so. If they didn't marching, they had to marching, otherwise they would wait to be killed or captured by Yang Rui's troops.

The situation was different at this time. Even if Cao Cao wanted to win over the princes around him, even if they knew that they had to make a move, they would probably lack sufficient conditions to send troops.

The most important thing is the issue of food and grass. When the princes of all parties were in the Huojia League, they consumed a lot of food and grass. At this moment, the princes of all parties were probably in a tight situation. When the Qinghuang did not take over, there was no surplus grain to send troops again.

At the same time, we must ensure normal marching and combat capabilities. The supply of food and grass in winter must be more expensive than usual seasons. Otherwise, even the basic physical consumption cannot be met. How can we fight? This is also the reason why Yang Rui doubled the supply to his own troops.

In addition to replenishing food and grass, it is also crucial to keep warm, such as cotton coats and quilts. Otherwise, if you are trembling with cold, you will not have much combat power at all.

In addition, marching and food supply transportation are also an important influencing factor. Yang Rui's troops have large chariots and horses to ensure transportation. The transportation still takes more time and energy than usual, and they are often stuck in the ditch and snow.

The transportation of materials does not only require transportation, but also a large number of horses, animal power, etc. Yang Rui has always paid great attention to the accumulation of horses and bought a large number of horses in the early days. Although the horses at that time were not necessarily excellent in physiques, they could be used for transportation purposes.

With all the restrictions, it was difficult for the princes of all sides to meet all the conditions for a while, which delayed the time to send troops to rescue Cao Cao, and even the conditions to send troops were not met.

There is also a saying that if other people’s affairs are not urgent, not all princes can clearly understand the consequences of Yang Rui’s attack on Cao, and not all princes have the character of daring to think and act. This has led to Yang Rui’s acquisition of half of the territory of Cao Cao, the Yin and Yin of Henan, but no princes have sent troops to make do.

Compared with the pressure Yang Rui faced, Cao Cao's situation can be said to be very poor. Yang Rui's army swept over like dark clouds. Not to mention the fact that the large player organization just came from behind made Cao Cao very uncomfortable, and he felt like he was constrained everywhere.

At the same time, the harassing strategy adopted by large player organizations such as Dragon Soul is very appropriate. Cao Cao could not focus his main energy on the western front. He had realized that Yang Rui might have to play the game this time and completely flatten his power.

However, the response measures Cao Cao could take were quite limited. Cao Cao also had all the shortages of materials and unfavorable transportation faced by other princes. Moreover, since Cao Cao spent some money during the Jiajia League, the situation was even worse than that of other princes.

Of course, it was not because the other princes did not send troops for the time being, so Yang Rui gave up his guard. Previously, Yang Rui placed Dian Wei, the most powerful troops, and placed his troops in the south route of Yin, in order to guard against the movements of Liu Biao's forces in the south and was ready to seize the Dongling Pass at any time.

If Liu Biao's troops sent troops to Silizhou, it would be most convenient to travel from Dongling Pass. Even if you can go to the foot of Taihang Mountain from the direction of Yuzhou, you can enter Silizhou. However, the detour was too far, and there were some remaining Yuan Shu's troops entrenched, which was basically difficult to travel.

At the same time, Yang Rui put the relatively easy-to-collect Yuzhou territory there. Some of the reasons are to restrain Liu Biao's energy, just because Liu Biao is located in the south. Although it is a very rare cold winter season, the restrictions Liu Biao should be subject to should be the smallest.

Liu Biao has coveted the territory left by Yuan Shu for a long time, and was deliberately stopped by Yang Rui before. Now Yang Rui has left this piece of fat there without moving. When Yang Rui was busy attacking Cao, Liu Biao is still likely to be moved.

While guarding against Liu Biao's power, Hanoi County was naturally the focus of Yang Rui's defense. He sent generals such as Cheng Yu and Huang Zhong to dispatch the number of troops who were not inferior to the siege of Hanoi County. Although it was useless at this time, it was also the most threatening point.

It is best if the Hanoi County people are not restrained. At present, Cheng Yu and Huang Zhong have divided up a lot of troops in the area along the Yellow River, and are always on guard against the route where Cao Cao might eventually escape.

The most important defense direction for Hanoi County is still Yuan Shao, Jizhou, with Qingzhou and Yanzhou as a barrier. Even if Yuan Shao wants to send troops to Jizhou, the greatest possibility is to choose the direction of Hanoi County, to surround Wei and save Zhao.

In addition, such as Zhang Xiu, Chen Gong, Liu Bei, etc., who have unknown whereabouts, have participated in the Huojia League. If they come out to reinforce Cao Cao again, the most likely direction will still be the direction of Hanoi County.

Regarding these forces that have almost disappeared from the three parties, Yang Rui has been asking the ethereal secret nuns distributed in various parts of the north to explore their traces, but no traces of these forces have been found at the moment.

Having said that, it is still necessary to say that the area of ​​the map in the game is too large. Even if Yang Rui has 50,000 useful Ethereal Secret Ninja Investigation soldiers in his hands and has the information center of Yusu Kan Bingwei to transmit information at any time, it is difficult to cover a large area.

For example, under the premise that the map in the game is enlarged by 100 times, Yang Rui's 50,000 Ethereal Secret Ninja in his hands are deployed within three or four states, which is equivalent to the actual density of 500 people deployed in several provinces.

In this way, it is normal for Yang Rui to be unable to find Zhang Xiu, Chen Gong, Liu Bei and other forces. As long as they hide their subordinates in a hidden mountain, forest or remote place, it is actually not easy to find.

This is also the reason why Yang Rui's troops quickly advanced and then stayed and screened for the remaining forces of Cao Cao's troops. This is also the reason why Yang Rui assigned a large number of vanguard cavalry from three groups, specifically used for interspersing, cutting, and finding Cao Cao's vitality.

Of course, after Yang Rui obtained control of the city node, even if some of the remaining troops of Cao Cao's troops were not completely removed, it would not pose too much threat.
