Could you recommend novels in which the main character had a system that could summon special troops and could become a general in ancient times (the best would be during the Three Kingdoms era)?

Being sucked into a fantasy world that nobody leaves doesn't sound half bad to Cain. He was a high school dropout with a drinking problem, living off disability due to his poor health, so it's not like he had much to lose except a few faithful friends he didn't talk to enough. After a long night of drinking, Cain wakes up looking at what he believes to be the character creation screen of one of his beloved virtual reality games, but with no recollection of having purchased it. His unwitting choice to use the Random Character Creation option, unaware that the choice would be irreversible, sends him into this new world as a Puppet Master, a Summoning based class nobody else in the starting zone has ever heard of. But as he soon realizes, this is no game, him and hundreds of others have been brought to another world with no instructions, no clear goals and no way home. It's a second chance to live a good life, but what will Cain be able to make of it?

Devastated by the harsh truth of being unable to summon a monster in a world full of summoners. Ban trained himself to death in the bid to overturn his fate.

Witness as this young man collects and contracts different kinds of monsters with the help of the Almighty Summoner System, becoming the Supreme of the Summoner's World and the worlds beyond it.

Imagine being forced to live, after death, as incorporeal bodies trapped in a vast space of nothingness for thousands of years, with nothing to do but exchanging past memories with other cohabitants (read: weirdos). Everybody wanted out, but there was no way to leave the Void... Until one day, a young man was finally summoned, as a powerful but reluctant mentor, by a bubbly and motivated but completely naive young girl. Baiyi, finally out of the Void, was the only one who could save all of the other 32 souls from their prison and his summoner might just be The Key to their freedom. However, Baiyi had to use the techniques and abilities the other souls had taught him throughout the years, and together with his own extensive knowledge of anime and game tropes from his shady and dangerous past as an otaku, to face the biggest challenge of them all: training the clumsy young girl he was forced to partner up with… into a competent sorcerer!

Bell Cranel was rejected by every familia he tried to join until he met Hestia. In a few, he was rejected quite violently. And in one particular instance, he was thrown out and bashed his head against a wall. Well, that's apparently where I come in. Not sure how and why I'm here. Not even sure who 'I' really am at this point since Bell's memories are definitely clearer than 'mine'... But I guess we're doing this. Hopefully I've got some useful cheats. Maybe?
