He wouldn't have known if he didn't prepare, but now that he did, Zhao Hai realized that he had thought too simply. He thought that as long as he got the oil press ready, he could produce fruit Oil.
However, when it was time to prepare, he realized that he still lacked a lot of things. First of all, they needed a place to wash the oil fruits. After the oil fruits were taken out, they had to be washed before the oil could be extracted. Otherwise, the hair on the skin would exist in the oil, affecting the quality of the oil.
Secondly, they needed to continuously put the oil press into the oil press, which required manpower and tools. Zhao Hai could replace the manpower with the undead creatures, but he needed to prepare the tools. Although he had a lot of living supplies, he didn't have the tools.
