In the Cultivation World, conventional artillery firepower was insufficient. Therefore, Chen Jiuge inscribed all bullets and shells with True Immortal Level Explosion Runes. This ensured each bullet possessed power no less than a True Immortal's attack, and each shell was equivalent to a True Immortal's full-strength strike.
Furthermore, this unique heavy truck possessed second and third forms: the Super Defense Mode. According to Zhu Yingque, its defensive capabilities were nearly the strongest at the True Immortal Level.
However, the heavy truck had a minor drawback: its speed was very slow. Compared to the vehicles described in the Jade Scroll, it was more than twice as slow.
This flaw, however, was precisely what Chen Jiuge desired. Being slow initially meant it was less likely to be targeted, enhancing safety in the early stages.
