Surviving in the Mist: My Undead Doppelganger Travels Between Two Worlds

【Island base + survival in the mist + lord + travel between two worlds + no heroine + no showing off + Undead System】 Wang Ling, a medical student studying abroad in the United States, accidentally transmigrated to a blood-mist survival world. From the start, he obtained a Book of the Undead and summoned an undead clone from it. Unexpectedly, the undead clone had its own stat screen and skills, and it and all the other undead minions it summoned could share everything with Wang Ling. Wang Ling also gained the ability to travel both ways between the real world and the survival world. Wouldn’t it make sense to start a business ferrying supplies between the two worlds? While his undead minions conquered new territory, he could focus on logistics and infrastructure at his island shelter, and even take vacations between the two worlds in his spare time. What could be better than surviving like this?
