Xiao Yeyang returned from Xintunwei, and Daohua briefly mentioned the matter of petroleum to him.
Xiao Yeyang expressed astonishment, "Petroleum? You mean rock paint, right? I've read about it in books. It's a type of oil that can be ignited for illumination. Does Xiliang also have this substance?"
Daohua quickly nodded, "Lifu knows where it is; let him take us there."
Xiao Yeyang took the matter of petroleum seriously, as he had read in military texts about people using petroleum to launch fire attacks on enemies. If petroleum was truly useful, then Xiliang's defensive capabilities could be greatly enhanced.
However, he disagreed with Daohua joining him.
Daohua shook Xiao Yeyang's arm, "There's not much going on at home right now, I'm too bored staying at home all the time; please take me with you."
Xiao Yeyang consulted Gu Jian, and after hearing that Daohua's health was well-maintained and she could go out appropriately, he agreed to take her along.
