“When the old gods are forgotten, they do not die—they wait.”In the year 1025, the Viking Age wanes.Iceland bows to Christ. The Althing governs by law. And the gods of old fade to whispers.But in the far Westfjords, something stirs.Vetrulfr, a former Varangian captain and exile, returns from the East with foreign gold, forgotten warcraft, and a hunger no man can name.He comes not in peace, but to raise Ullrsfjörðr from ash and ice; building walls, carving runes, and waging war on behalf of a dying faith.From Reykjavík to Aachen, rumors spread: a ghost walks the North once more. Some call him the son of Ullr. Others, a wolf-cloaked demon.But all will know his name.and when the Valkyries call, he will answer.

Rune was just an ordinary man from Earth — until fate threw him into Ninth Dawn, a world of swords and magic. Reborn in the frail body of a child cursed with an F-rank Divine Blessing, Rune’s new life was nothing but suffering.Branded with false accusations of rape and murder, he was captured by the Seraphic Order of the Black Veil (SBV). Brutally tortured and executed for crimes he never committed, his story should have ended there.But death wasn’t the end.Time rewound. Rune opened his eyes once again to the moment of his first reincarnation.This time, he vowed vengeance.Guided by Nexar, the Warlord’s System, Rune carved his path through blood and fire. He conquered territories, raised armies, and earned the fearsome title:The First Warlord of the Dawn.Yet even warlords fall. At the peak of his conquest, Rune was struck down by the hand of the Demon Lord — the true shadow looming over the world.And then… he returned once more.Back to the very beginning.But now, something had changed.The system reincarnated with him.Only, it wasn’t the same.Nexar had awakened anew as:Nexar, the Warlord’s Carnal System.With vengeance burning in his heart and a twisted new system at his side, Rune is ready to defy fate itself.War, blood, lust, and conquest — his dawn has only just begun.

The top alpha, Major General Ji Cheying, disguises himself as a down-on-his-luck beta in order to carry out a secret mission. One day, when he goes out to take out the garbage, while wearing a pair of torn socks, he comes across the poor nephew of his landlord, Xie Quan, a good-looking beta who was staying in the dirty and terrible basement.

The two look at each other, each feeling a little sorry for the other.

No one expected that one of these two miserable people was the prestigious Major General Ji and the other was the most powerful mecha engineer in the Empire. And to Ji Cheying’s further surprise, this beautiful beta confessed his passionate love for him!

He was torn again and again under the prudent choice to refuse the other, after all, this is a mission, not the time to talk about love.

When the mission was over and it was time to talk about love, it was Xie Quan’s turn to become baffled, “Who do you think likes you? Who confessed? I didn’t, I’m not, don’t talk nonsense.”

Ji Cheying: ???!

It was only then that Xie Quan unexpectedly realized that the Imperial Major General seemed to have mistakenly thought that he was in love with him.

A few months later, Major General Ji, who had entered his susceptible period, was violent and fierce, not able to be approached by strangers. However, his eyes were red and he was tugging at Xie Quan, his voice hoarse, “You little liar, cheating on my feelings and not taking responsibility.”

Xie Quan sighed, lifted his hair, and tore off the invisible gland patch, finally revealing the omega gland at the back of his neck, “Bite it. I’ll give you a bite.”

Ji Cheying gritted his teeth, “You’re a f*cking omega?”

True love has nothing to do with identity and gender.
