Liu Feng possessed the power of the Rinnegan as well as Ten-Tails Chakra, so of course he could undo the Infinite Tsukuyomi.
In the original story, Naruto and Sasuke had needed to work together, but Liu Feng could undo the Infinite Tsukuyomi on his own.
After forming the Rat hand seal, the Infinite Tsukuyomi was undone. Everyone who had been entangled by the Divine Tree was freed, while the White Zetsu Army had already been completely wiped out.
