Nalan Song was stunned, "My lord, these snowman puppets cannot be moved!"

Su Yin said, "Why can't we move? Xia Chongguang can use millions of snowman puppets to attack the Central Plains, but I can't use 200,000 snowman puppets to build city defenses? I promise you, once the fortress is built, we will use the barrier passage to

Send them all back to Tianfeng Mountain."

Nalan Song frowned and finally nodded, "I don't have any problem, it's just that this place is located in the southwest..."

Su Yin smiled and said, "Yes, it sounds like the snowman is seeking death when he comes to the south, but you will know it just by looking at the location of the fortress I chose."

Everyone looked at the fortress locations drawn by Su Yin. One of them was located on the southern mountain range, with constant cold winds all year round. Even on this southwest border, it made people shudder.

The other place is in a valley, firmly defending the passage between two large mountains, blocking the road to the Central Plains.

The last place is on a tributary of the Lihe River. Although the climate is not too cold, it is much cooler than other places in this province.

Su Yin said, "Winter will officially begin in one month. By then, the weather should be enough for the Snowman Puppet to survive. We will use the entire winter as the construction period. We will complete the foundation excavation before the ground freezes in winter and build the three fortresses before spring. Moreover.

These three fortresses..."

Having said this, Su Yin beckoned Nalan Song to come closer and mysteriously placed a drawing in front of his eyes.

Nalan Song gasped in shock, "My lord, where did you come from this thing? I thought it had been destroyed in the war a thousand years ago."

Su Yin laughed and said, "I knew you could understand it, so don't ask, just do it."

Su Yin did not tell Nalan Song that the underground structure layout of the fortress was officially collected by her in Tianfeng Pavilion. Nalan Song's admiration for Su Rao was like a declaration, so naturally he would not go to her room to look around, so he already

For thousands of years, he has not found this blueprint.

The drawings record the underground defense structure of the fortress, and there are even some simple pipeline facilities. The thicker ones can be used to transfer personnel and materials on weekdays, so that no one can notice. In wartime, if the city is broken and it is necessary to abandon the city and escape,

You can even escape through pipes, or pour fire oil to reduce the city to ashes.

This map was probably prepared by Su Rao for the Tianfeng Mountain Fortress. However, in the end, Tianfeng Mountain only built an immortal wind array, but it did not become a real fortress. This structure

Pictures have lost their effect.

However, the deployment methods recorded on the drawings are extremely valuable even now.

"Nalansong, I will ask Liuli and Yuchifeng to assist you, and recruit two hundred soldiers to serve as your deputies. Within one month, I will have two hundred thousand snowman puppets pass through the barrier and come to Dingnan Province. Can you do it?

"

Nalan Song nodded, "No problem."

Su Yin smiled, "Okay, the first step went well. Then before the snowman arrives, we still need to ask for something. As for the sponsor this time!"

After saying that, Su Yin paused and then said, "Gu Xueqiao, you are responsible for returning to the capital of Qin Dynasty and continue to find Prince Yue. If he doesn't give it, tell him that I want to give up my son. No matter what, we must build the city.
Chapter completed!
