The announcement about the disaster situation suddenly seemed to be nothing important. Yang Rui's jurisdiction was full of food and clothing. Even if it was twice as cold, there would be no problems.

But the key to the problem is that the system announcement is that the civilized areas of the Three Kingdoms encounter a cold winter once in a century and the mountains and rivers are frozen, which means that the Yellow River is likely to be frozen!

Then contacted the Huojia County, where Yuan Shao invited a group of princes to join forces, which happened to be on the edge of the Yellow River, and shone with Guandu City. If the Yellow River is frozen, Yang Rui will lose a natural barrier.

You should know that Yuan Shao has always wanted to cross the Yellow River because a powerful naval army led by Gan Ning blocked the progress of his troops. Once the Yellow River is frozen, wouldn’t it take a bridge to fly north and south, and the natural barrier becomes a thoroughfare?

If the princes responded to Yuan Shao's call and went to Huojia County to meet the alliance, the trouble would probably be even greater.

Yang Rui was not worried that he would eventually be unable to resist the enemy, but he just lost the obstacles of the Yellow River out of thin air and lost a great advantage in the land. This is a pity.

Furthermore, if the water surface of the Yellow River is indeed frozen, Gan Ning and its fleet will also face some problems at this time. Whether it is a building ship, a trolley, or a large and small ship, they will face the situation of being frozen on the water surface.

Under such circumstances, the power of various ships themselves will not only fail to exert, but will instead become trapped beasts and become targets of enemy attacks. Yang Rui considered this at the first time.

Therefore, Yang Rui didn't care about dealing with Cao Cao and Zhang Xiu's troops at Dongling Pass anymore, but instead put away the crowd at the fastest speed, and drove the Xu Du flying boat and quickly rushed towards the direction of the Yellow River.

The content of the system announcement seemed to be a gradual process. At least when Yang Rui came to Dongling Pass from Jizhou, there was no sign of ice in the Yellow River.

According to the natural phenomenon of the game, it is impossible for the system to be frozen immediately as soon as the system announcement was released. After that, the news obtained by Yusu Kanteng through the Ethereal Secret Ninjas was that the fruit of the Yellow River did not freeze immediately.

"Transfer to Gan Ning, and ordered him to give up defenses along the Yellow River, and urge all his ships to enter the Ji River. After that, all the warship officials of all sizes and warships also retreated into the Ji River..."

After Yang Rui learned about the relevant situation, he immediately conveyed the order to Gan Ning to urge his ships to evacuate and withdraw troops, and immediately chose to give up the defense of the Yellow River Navy.

There is no need to say much about the speed of the Xu Du Flying Boat. In about half an hour, Yang Rui had already reached the surface of the Yellow River near Chenliu County. At this time, the temperature here has indeed dropped a lot, and some ice has even appeared on the bank of the river.

Not long after, Yang Rui had already arrived at the fork between the Yellow River and the Ji River, and saw that some transport ships, merchant ships and the like had appeared one after another, which were all used by Yang Rui's transportation and business operations.

It proves that Gan Ning is already executing Yang Rui's order to transfer the ship, but this process will definitely take a long time.

Since the existence of the Yusu Knightmai and the Eagle Secret Ninja, Yang Rui's communication methods have undergone considerable changes. Not only can he obtain comprehensive information through the Yusu Knightmai, but he can also issue some urgent orders through it.

Of course, Yang Rui rarely uses this method, and still mainly uses conventional communication methods. Every time he uses Ethereal Secret Ninja to pass the command, Yang Rui made an agreement with the generals in advance.

It is equivalent to a realistic encryption method to avoid any emergency situations in the Elf Secret Ninja or the Issu Cangwei, which will cause false orders.

According to the situation in previous years, the Yellow River in the game is different from that in reality. It may be due to the widening of the river surface and the increase in flow, or the climate temperature in the game is not so extreme. Although the Yellow River is frozen, it will not freeze all the river surfaces, and it can basically ensure navigation.

However, shortly after Yang Rui arrived at the bank of the Yellow River, the sky became gloomy. After that, snowflakes floated and soon turned into heavy snow. The temperature dropped sharply again, and the ice on the shore gradually increased.

At this speed, it is probably not long before the entire Yellow River Lake will freeze. Once the ice is completed, it means that Yang Rui completely lost the Yellow River barrier, and that the ships may not be able to evacuate all into the Jishui River at that time.

Under such circumstances, Yang Rui could not sit still and drove the Xu Du Flying Boat and patrolled the water surface of the Yellow River. Along the way, all the way, all the boats of all sizes were rushing towards the intersection of the Yellow River-Ji River.

Most of them were transport ships and merchant ships, and they were still in a period of war. It can be seen that the economic benefits that the Yellow River water transport can generate, and most of them were ships to which Yang Rui belonged.

However, at this time, Yang Rui did not have much energy to pay attention to these things, but was always paying attention to the growth of ice on the river surface. After the ice on the river gradually showed a trend of spreading to the center, Yang Rui decisively issued another order.

All the members of Ganning and its ships began to move towards the Jishui River. At this time, the members of Ganning and their subordinates had basically announced all the ships on the surface of the Yellow River, and there were not many ships left that were not notified.

After patrolling the water surface of the Yellow River and the Ganning Navy began to move, Yang Rui suddenly had an inspiration in his mind, remembering Cao Cao's use of water to kill and build an ice wall, and temporarily mobilized some of the reborn warriors of the Supreme Yiji to try.

After trying, Yang Rui could confirm that even under the background of the game, the system recognized some of the most basic life phenomena. After a group of reborn warriors fetched water and sand, a large wall was built up.

Even if the water and sand condense at a speed of not being very fast, the temperature of the surrounding environment cannot reach the level of ice dripping water, but it is just right for construction.

With this verification, Yang Rui naturally would not miss this opportunity easily and began to mobilize manpower to the south bank of the Yellow River.

Previously, hundreds of thousands of Cao Cao and Lu Bu were originally in the area near the Yellow River, and they were always repairing the city along the river to rush to the city. At this time, after urgent mobilization, it only took half a game day to reach the bank of the Yellow River.

Even if some people are far away, as long as the conditions for pouring water and sandy cities exist, it will not be too late to proceed later. Even if the surface of the Yellow River is frozen, the ice layer needs to reach a certain thickness to bear the advance of Yuan Shao.
