After a while, I suddenly heard two sounds, and a fire ejected from one end of the elliptical device.

Li Qi was amazed at the sight.

Ershun explained: "Under this shaking, the juice and green water inside will react and become a gas with heat. Once this gas is exposed, it will burn immediately. In fact, Bifang is spitting a gas, not a fire. This is why Bifang must spray fire, because when the gas in the airbag reaches a certain concentration, it must be released, but once the gas leaves the closed airbag, it will burn immediately, so it looks like it is spraying fire."

"I see."

Li Qi nodded and said curiously: "Then...what is the blue liquid you had before?"

The ear said: "That blue liquid is because of the addition of too much green water."

Li Qi said in a daze: "What does it mean?"

Er said: "Although we found out the secret of Bifang's fire-breathing, the gas is inconvenient to preserve and even more inconvenient to use. We thought of many ways, but they failed. Until one day, we learned from the leader of Bifang that they cannot eat too much green water, otherwise they will get sick and cannot breathe fire. We have proved before that Bifang sprayed gas, that is, too much green water, even if it shakes, it will not be able to produce gas. Therefore, we added too much green water. After many experiments, we finally found a suitable formula, adding a certain amount of green water to ensure that the gas is not produced, and it can be ignited with fire."

"I see."

Li Qi nodded, looked at Ershun excitedly, and said, "Thank you so much for you."

He replied: "No, no, no, this is what we should do. We are very grateful to the Chief for you to win an identity for us."

Li Qi smiled and said, "This is what it should be."
