The four of them coincidentally witnessing this scene was all part of Lin Tian's calculations. The punch from Lai Xiucheng couldn't possibly send him flying; it was Lin Tian who deliberately leaned back to create the illusion.
Lin Tian had been through battles beyond their imagination, crafting such a small illusion was a piece of cake for him.
He flew back directly towards Principal Yan, who, clenching his teeth, actually stepped forward intending to use his own body to block Lin Tian to prevent him from colliding with the wall.
Lin Tian also noticed Principal Yan's intention and found it strange. Since when did the principal care so much for the students?
However, Lin Tian couldn't truly crash into him. Principal Yan, being middle-aged and having sat at a desk for long periods, as well as frequently socializing, was not physically robust like those leaders and couldn't withstand a collision.
