The smoke and dust from the explosion gradually dispersed. Amid the lingering haze, a six-meter-tall black humanoid machine appeared before everyone.
This black-grade mecha was one of the subjects of this experiment. At six meters tall, it was not particularly large for an ordinary black-grade mecha, and was even somewhat short.
But in Huo Yuhao's view, height was not important. After all, an overly large frame would instead prove cumbersome in combat. Back then, in the underground research facility of the Sun Moon Royal Soul Engineer Academy, Huo Yuhao had seen the giant humanoid soul tool code-named Number One.
Although he had been deeply shocked by its towering frame at the time, after later simulating and working through it in his mind, Huo Yuhao had discovered that an overly large body could not display combat power matching its enormous size in battle.
After all, rather than making it so tall, it would be better to simply have it fly, giving it even greater mobility.
It was also an extreme waste of materials. More importantly, an overly large frame, especially one standing on the ground, would instead become a sitting duck.
After all, the enemy only needed to deploy enough soul masters equipped with soul tool flying devices and Fixed Soul Cannon Shells to counter such an enormous mecha through mobility, or even infiltrate it and destroy it from within.
Furthermore, the personnel required to operate and maintain it, and even escort and protect it, would be enormous in number, making it a burden in battle instead.
Thus, this mecha had not been designed to be so tall. As for why it was a black-grade mecha rather than a red-rank mecha, the reason was also simple.
That was because red-rank mecha required a relatively high level of manufacturing capability, and the
