Soon, however, Xuan Ziwen dismissed his initial contempt for Huo Yuhao. Huo Yuhao possessed solid fundamental skills; although the engraved soul tool core circuits were somewhat rough, their functionality was clear. It did not take long for Xuan Ziwen to figure out what Huo Yuhao was working on—he was building an adder.
A so-called adder was essentially a device used to perform addition. To build one, a person first had to master the logic of the "AND," "OR," and "NOT" gates, combine them properly, and hold a complete operational flowchart in mind.
Do not underestimate the making of an adder; it did not require profound core array carving techniques, yet it was a concept that many junior Soul Masters struggled to comprehend throughout their entire lives. How to set the addend and augend, how to generate logical operations to yield the sum and carry—these were fundamental tests of a Soul Master's baseline skills.
