Metal sparks violently tore through the rain curtain, shooting onto the train's deck.
On the other side, Lao San simultaneously operated a heavy machine gun to shoot at the train.
But whether it was 12.7 or 14.5 bullets, they showed no signs of ricocheting off the train's body.
Su Huan squeezed the handrail at the edge of the watchtower, and suddenly Vice President Deng's excited voice came through the communications device made by Professor Ma beside him.
"Report to the train captain, not a single bullet penetrated the train's armor. I request to proceed to the next test."
Su Huan's mouth curved upward, "Go ahead."
As soon as he finished speaking, a red light appeared on his pale palm, and flames spontaneously emerged, gathering into a small fireball that, over time, transformed into a fiery spear.
This fire spear was infused with half of his body's energy.
