So that was the catch; no wonder he felt something amiss as soon as his thoughts started to wander. So he can't summon a mercenary above his realm, well that was a big demerit that severely restrains all the plans Yang Chen had for this option.
"Don't be too hasty to judge this option. While it may be true you can only summon mercenaries up to your realm, the mercenaries summoned are all powerful entities drawn from ancient battle contracts sealed within the system— beings who once walked various worlds and left legends behind"...
"Depending on how you use them, they can shift the tide of battle, assassinate key targets, or serve as distractions while you act in the shadows".
Yang Chen fell silent. The next second, he opened the option and started browsing it. Like the demon said, he cannot just judge the option without even looking at it first.
