[BL] Accidentally Becoming the Healer of the Deranged Archduke - Chapter 284: Evil Darius

This is an alternate history. Decades after the fall of the Eastern Jin Dynasty, the world is still in chaos, although there is hope for reunification.

A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century. The body that he is occupying was the imperial prince of a failing empire who suddenly rose to power after a successful assassination attempt of his father. Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory? Or will he succumb into a conspiracy lurking within the country's borders?

Jaxon Hawk pretty much lives inside, loving his own space, when BAM! He gets this crazy thing called the Sniper System just as the world goes totally bonkers with zombies. But these aren't your grandma's zombies, shuffling around and moaning. Nope, these guys are like Olympic athletes, running, jumping, climbing, basically doing everything to get you. And get this, they keep getting stronger and tougher each time they change! Every time you meet one, it's a fight for your life.The human race is on its last legs. The good thing is, everyone knows they have to work together or they're totally done for. This isn't a story about fighting other people, it's about not becoming zombie food. Regular folks don't have a shot, and even soldiers are sweating bullets. This is a hardcore survival story, where Jaxon has to use his new skills and think smart to keep himself, his family, and his new friends safe.It's a wild ride of thrills, trying to stay alive, and finding people he actually cares about. Oh, and there are some girls, too, making things even more interesting. It's all about big feelings, scary moments, and doing whatever it takes when every second could be your last.

Programmer Li Daochong desperately develops the game code, dying. After waking up, being born again in a ghost-invading future comprehension world, isn’t that a pothole?

However, Li Daochong brought his own ghost upgrade system, which made my green onion. Others are devilish and scared, and they rush to hell. Hey, isn’t this the tip of China? I want to eat, drool!

Eating is not the most important thing. The key can be upgraded. How many levels does it take to finish?
　　
“Li Daoyou please stay, people want to go to the edge of the magic field on the edge of the magic field, can you accompany others? People are afraid!” Hongyang fairy is dripping at Li Daochong.

“Li predecessor, can you please go with a younger generation to go to a ghost dragon?” A white-haired girl who is more than two hundred years old can look at Li Daochong helplessly.
