The scale of this new type of bastion does not need to be very large. Each bastion only needs to accommodate 500 people.

Moreover, the outer walls of these cold forts are all made of rammed earth instead of expensive blue bricks. This also greatly reduces the cost and time of building forts on grasslands with poor materials.

This entire set of bastions was basically copied by Zhu Han based on mature bastions in modern Europe.

However, the core parts of the fortress were carefully adjusted by Zhu Han to adapt to the environment on the grassland.

For example, in order to adapt to the harsh climate on the grassland, a very deep basement was specially built inside the bastion, using the constant temperature properties of the earth to ensure that the defenders could get enough warmth in the cold winter.

Using this set of Ming Dynasty version energy protection, Zhu Han had sufficient confidence in restraining the nomadic tribes on the grassland.

Soon after, the Ming Dynasty appointed Luo Guanzhong as the governor of Yingchang Town, the northern parallel capital. Tong commanded 5,000 troops to build a fortress on the grasslands around Yingchang.

Yunnan, Puzhou.

Since Chen Youliang's Han army captured Dali City and Kunming City, forces from all over Yunnan have voluntarily surrendered. Only Puzhou still persists in resisting, because Dali's general manager Duan Qinggong led the remnants of his troops to flee to Puzhou.

"Chen Youliang, this thief, I heard that he has assembled an army of fifty thousand and wants to attack Puzhou! General Manager, what should we do?" a general asked Duan Gong, the General Manager of Dali.

"When the soldiers come, we will cover up the water and the earth. We must not surrender!" Duan Gong said firmly.

"General manager, what should we do now?" Another minister continued to ask.

"Order all soldiers to be ready for battle and to fight against the bandits at any time." Duan Gong said.

"Yes, General Manager." The general agreed immediately.

Duan Gong didn't stay in Puzhou for a long time, just over half a year, but he had already established a good reputation and planned to restore the title of King of Dali with the support of everyone.

This is not because Duan Gong gained his prestige, but because he has the blood of Duan family in Dali, which makes the people of Puzhou very convinced.

In this way, the Dali army stood firm in Puzhou City, and Duan Gong personally patrolled the city for several days to prevent the enemy from sneak attacks.

Suddenly, there was a rapid sound of horse hoofbeats. Duan Gong looked up and saw smoke billowing in the distance, and a horse running towards him quickly.
