"Did he apply the herbs on the inside and cover it with banana leaves?"
Bai Zhe applied the sauce and the herbs before leaving it there to let the sauce absorbed into the meat and the skin. Then, he turned to take care of the snakes by skinning them and taking their plucks. Some of them had venom bags. So, he had to carefully take them off. Then, he showed outstanding knife skill which made everyone surprised.
Bai Zhe could debone the 3 snakes swiftly as if he were an experienced chef who had been making food from snakes for years. The truth was that Bai Zhe had the Intelligence team find the experience of chefs from all around the work for him so now he could easily use the expert cooking skills.
Bai Zhe marinated the snake with herbs to reduce the smell. Then, he went to put the boar up on the bonfire that he had set the Y-shaped sticks on both sides. He did not forget to make the handle to turn the boar as well.
