A Bored Lich - Chapter 162 - Amphiboards

300 years after becoming a Demon King, the war angel Ansel faced a serious problem during a certain expedition.

——His halo grew out once again.

Ansel picked an auspicious place that was definitely and absolutely unmanned, and while cursing, he simply and skillfully broke off the newly emerged angelic aperture.

This thing was growing out faster and faster!

When will his undercover mission end already?!

The demon realm was divided and ruled by three kings. Demon King Saros was forced to go on an expedition with his sworn enemy, Ansel.

One day, he noticed Ansel sneaking away from everyone.

Saros decisively followed him, and was shocked to find that his sworn enemy, another demon king of the demon realm, took off a horn headband and fake bat wings. As Ansel cursed up and down, Saros watched as he skillfully removed a cute halo from his head.

This irritable, easily angered guy who loves fighting; the type that was cute when he shuts up but could make even demons angered to the point of ascending to heaven the moment he opens his mouth…

..was actually an angel???

PS. Cover not mine, I just found it on google.

I was reincarnated as the supporting character of a novel. As a wingwoman in a depressing romance novel titled at that. Romance is out of the question, and the future of my family is ominous because of debt. I was going to become a civil servant to gain some of the splendor I never got in my last life…but the male love interests are acting kind of strange?! “Just think about it, does Shushu look like someone who would blush and act shy?” “Wow…….that would be great.” Cory said as he stared at Hylli in a daze, and Yves frowned and whispered to himself. “Should I just kidnap her…….” Swan wrapped his face with both of his hands and stayed quiet. His face turned bright red. The blush turned his ears red. Why are you guys fooling around, you’re supposed to be obsessing over the heroine. The story of Shuraina West, Shushu’s reverse harem academy survival. Note: Ojakgyo means wingman/woman!

【Your descendants in the Immortal Cultivation World have offered a plate of snacks】【Incense Fire Value +10】【Would you like to reward your descendants?】Yang Genshuo was surprised to discover that offerings in the Immortal Cultivation Family game could actually appear in the modern world, and that modern items could also be bestowed upon descendants in the game.Years later, peculiar rumors about the Yang Family spread throughout the Immortal Cultivation World.“To break through from the Fetal Breathing Stage to the Qi Refinement Realm, one needs to refine a strand of heavenly and earth's spiritual energy. I've heard of Red Flame True Qi, Xuan Water True Qi, and Green Wood Spirit Energy, but Yang Dao-friend, this... Liquefied Natural Gas, what kind of spiritual energy is it? How is it condensed?”“I've heard that the Yang Family's Spiritual Plant Technique is incredibly sophisticated, with each mu of Spirit Rice yielding twice as much as top-tier Spirit Plant Families, all thanks to a strange secret technique the family disciples cultivate called 'hybridization'.”“The Yang Family’s art of elixirs is unrivaled in the world, with new elixirs constantly being created. It is rumored that a spirit of the elixir named 'Artificial Intelligence' tirelessly deduces elixir recipes day and night...”“Nowadays, the Thunder Cultivators of the Yang Family are exceptionally strong, all thanks to the Yang Family's effort in creating a top-tier Thunder Gathering Array. Thunder Cultivators who enter this array can increase their cultivation speed multiple times. It is said that the array eye is known as—the power station.“As the Yang Immortal Cultivation Family grew stronger, Yang Genshuo actually became the only Immortal in the modern world by consuming offerings!Years later, facing an endless stream of people ascending the mountain to seek the Dao, Yang Genshuo calmly said,”There are no immortals in this world; you must believe in science!“Then he soared away on his flying sword.
