Black King's Spokesperson: Becoming a Slave at the Beginning?

[Western Fantasy + Multiple Heroines + Yandere + Slave + Status Reversal]

Lu Mingyu traveled to another world and was attacked by goblins. Despite his best efforts, he was unable to defeat them.

Because of his black hair and black eyes, he was imprisoned in a castle by a yandere female noble.

In this world, protection is king.

It is to sign a slave contract.

Or escape from the clutches of the female noble?

Lu Mingyu glanced at the protection above his head:

[Xia Clan Protection]——A natural born alchemist, skilled in making nuclear bombs and mass-producing airplanes and tanks!

[Time Traveler's Blessing]——You can learn other people's skills at a glance, travel through time and space, and change cause and effect!

[Spokesperson of God-King Odin]——The all-seeing eye, the vision of God, the legendary Valhalla where epic heroes gather!

[Spokesperson for the Black King Nidhogg]——Word Spirit Time Zero, Emperor, Kingship, Black Sun...!

With a cheat in hand, how can I avoid her edge?!
