The human heart is the most difficult to measure in this world.
Li Yu never thought about expanding the base to make it more powerful; he was content with just holding a corner of safety. If they really encountered an undefeatable enemy, the worst-case scenario would be sacrificing the base to avenge their lives.
However, as time passed and the base developed, he, as the person in charge of the base, felt that there were many more factors to consider.
The burden on his shoulders pushed him forward.
But he always held firm to one belief: the human heart is unpredictable, and only the strength of guns is absolute.
If the control is not strong enough, too much growth might backfire.
Therefore, he was very cautious about this.
The establishment of four levels was Li Yu's preliminary test, validating his thoughts.
If problems arose, with his personality, he might directly deal with the people causing the problems, as he could not tolerate any dissent.
