The soldiers would significantly benefit if they followed Su Binglan's methods. Then, they might no longer need to rely on military pay to live. The soldiers could earn extra income, and their families would have jobs.
Many soldiers did not have much to eat even after receiving a retirement pension. There were also family members of soldiers who had sacrificed their lives. Those who were not capable could not eat their fill.
It was as Su Binglan said. Everyone could eat their fill and wear warm clothes if the village prospered.
They could work while they were young and robust to earn money. Then, they could use the money to help their families. They might even become wealthy.
Many soldiers only had one thought when they first joined the army, and it was to not starve to death. At least they had some food in the military camp. Everyone just wanted to survive.
