They said it was easy for them, but you could see for yourself. Even lifting so much, Mei Mengzhen looked relaxed. But the scene was quite horrifying.
As for Fan Tianyu, there's even less to say. Back when he sold vegetables, moving and transporting goods was all done by himself. Even if he does it less now, his strength hasn't faded quickly, so he also found it easy.
Seeing the two of them handling it with such ease made He Yiran feel rather helpless. She was bigger, but her strength was minor. One box was already the limit for her, and even that was a struggle. After moving two boxes, she stopped and took a bottle of water to stand aside, sipping and watching the others "bricklaying".
