Chain Gun?

Hou Zitao seemed to have been punched right in the chest. His face was extremely pale.

He had always been an enthusiastic and outgoing man, otherwise he wouldn't have been asked to greet Li Yao.

But, however enthusiastic he was, he was still quite depressed when Li Yao asserted that his research would only be paperwork.

The other young refiners were greatly shocked to see the formulas that Li Yao provided, too. But their studies were not focused on gun-type magical equipment, and they found many formulas very confusing.

However, they could tell from Hou Zitao's expression that he had been completely awed.

"Sister Long."

Xie Anan dragged Long Yunxin back and asked in a low voice, "Is Sand Scorpion very skilled in refining, too? I don't understand the formulas he listed nor the buffer rune array group that he constructed just now."
