During this time, these construction workers and Li Yu along with others have been eating and drinking together.
Like the communal pot meals of the past, sharing food and drink.
Moreover, since these construction workers were initially rescued by Li Yu and his group, not only that, they also helped them find their families later.
And then they united together to successfully build Weng City, defended against the zombies, and went out together to kill people!
In other words, they had been through quite a lot together during this time, and Li Yu had been continuously observing these people, and after this period of evaluation, at least up to now, Li Yu felt that they were quite honest and reliable.
And the latest incident where they killed Big Gold Teeth and others, also made them deeply understand Li Yu's ruthlessness, willingly being led by him.
Now, they had really integrated into the group.
....
The dinner that day was good.
