Li Xiu proposed the news about using hot air balloons, so he was responsible for this matter. In fact, the launch of hot air balloons is quite complicated, especially in the current weather, you must calculate the direction of the wind and the destination. Otherwise, if it is a little bit off, the hot air balloon may be far away from the target when it lands. With the current snow, I am afraid that the person who reported the news will be frozen to death on the snow field.

Fortunately, the wind direction has been very fixed these days. There was such a strong wind last night, and today's wind has become much smaller immediately, which can barely lift the hot air balloons up. In addition, they also know the position of Dingxiang and Qin Qiong's army. Calculation is also the strength of Li Xiu, so he can easily figure it out.

However, the wind direction was a bit tilted, and there was a deflection angle between the hot air balloon and the destination. Fortunately, it was not very large, so Li Xiu asked someone to dig a few kilometers southwest to let the hot air balloon take off, which can minimize the distance between the hot air balloon and the destination when it lands.

After watching the hot air balloon take off and slowly float to the north under the blow of the wind, Li Xiu breathed a sigh of relief and then went to see the excavation of the road. The first army to excavate the road had been organized, with only one thousand people. After all, the width of the road was limited, and too many people could not be used.

The snow is still very soft and easy to dig. The soldiers in front are responsible for loading the snow onto the car, while the other soldiers push the cars behind and pile up. They don’t have to clean up all the snow on the road, but leave a layer, which can facilitate the passage of the sledge.

Speaking of sledge, although it is very convenient to walk on the snow, the snow cannot be too thick. After all, animals need to pull the sledge in front. For example, in this heavy snow, horses can only have one horse's neck on the snow and cannot move their legs at all. In this way, sledge can't be used.

The soldiers digging the snow were busy, and Li Xiu also saw Su Dingfang in the crowd. He was only wearing a single dress, pushing a small cart with both hands, and steam came out of his body. He was very strong, and one person could use three people.

These soldiers who dig the roads were carefully selected and strong men, and they moved very quickly. In a short while, they dug out a road about ten steps wide and several miles long. At this speed, it is estimated that it will take less than two days to meet Qin Qiong in front of him. As for Li Ji behind, they should also send hot air balloons to contact them. Of course, there are also a group of soldiers in the north digging the road in Li Ji's direction, hoping to get the three armies together as soon as possible.

Li Xiu did not disturb Su Dingfang, but went back after watching for a while. However, as soon as he entered the tent, he saw Yue Chan crying while packing things. This made him ask in surprise: "Yue Chan, why are you crying? Are you scared? It's okay, it's just a snow. Master, I have already thought of a solution. We can definitely go back!"
