Road Survival, I Have a Hint System!

Waking up with a hangover, Zhang Tuohai found he had entered a game called Road Survival.
One person, one car, searching for supplies on the road with no end in sight, struggling to survive.
In this game, crises were aplenty and many people had perished because of the search for supplies.
Zhang Tuohai found that he had bound to the hint system.
Stop! There is a level 4 material box hanging from the treetops on the side of the road with an RV upgrade blueprint inside.]
While everyone was still careful and had difficulty surviving, Zhang Tuohai could already drive his RV and eat hot pot.
