It's the Windmill Whip.
Chen Yi recognized that whip technique; when at the Southern Border, Qin Qingluo would occasionally take him horseback riding outside the town. Seeing that his riding skills were mediocre, she would disdainfully teach him various whip techniques, including this Windmill Whip, which the people of the grasslands use to drive horses. The tip of the whip spins like a windmill, circling and striking down, causing the horses to run wildly. Yu Wen Yuan, at this moment, looked just like that, with light in his eyes, his mouth grinning, concentrating on raising the whip, focusing only on charging forward.
The thoroughbred galloping as if its life depended on it, racing so fast, with hoofbeats like rolling thunder.
Chen Yi rode alongside him.
