Zhang Yu could instantly tell that the flying swords on the field were completely different from the toy flying swords he had bought before; clearly, they weren't something you could easily play with.
Despite the dissatisfaction in the audience, the host calmly recited the advertisement, and then started to announce the rules for the first match.
The flying swords floating on the field at this moment were products of the flying sword manufacturer 'Nine Heavens Flying Sword', a type of civilian-use mana flying sword.
They claimed that there was no need to learn any swordsmanship, no Dao Heart Level requirements, and that just by changing mana output, you could control the flying sword, testing one's ability to control the flying sword using mana.
The scabbard of the flying sword acted like a remote control and mana transmitter, enabling control over the flying sword through variations in the frequency, type, and amount of mana input.
