My Broken Sabre Has Murderous Intent

1000 years ago, the humans of the Blue Planet, who were venturing into space for the first time, accidentally entered an alternate dimension battlefield. The world entered the cultivation age.
With the core of stars as their foundations, they activated talents and tempered the star veins. They were called the star warriors.
Lu Lin, who had transmigrated to this world, activated double talents during his national examinations:
His star power was doubled, so his combat flight time approached infinity.
His potential was doubled, so his double talents would improve each other.
His combat ability was doubled, so his sensing ability could help him easily find his opponent’s weak spots.
His survival ability was doubled. By seeking advantages and avoiding disadvantages, he became the survival master in this alternate dimension.
His threatening presence was doubled. With a death stare, he could rob the enemy of their will and leave them helpless to the slaughter.
Many years later, Lu Lin was given the titles Demon King of Humans, Incredible Perpetual Motion Engine, Human Techniques Collection, The Nightmare of the Other Races, Battlefield Treasure Harvester, Desolate Environment Survival Master, Universe Lord of Fortune, Secret Zone Overseer, etc. 
When he was being interviewed, he said, “I truly am just an ordinary person. If you wish to do what I did, it is actually very simple—you just need a pair of eyes.”

Exotic Battlefield: I Can Activate Dual Talents

<p>Every Star Guide who came here had an exclusive tent. However, very few soldiers were lined up before the other tents; everyone was crowded outside Lu Lin's.</p>

<p>Lu Lin hadn't rested all night. To accelerate his Star Vein Refinement Degree, he had spent the entire night successfully Guiding Star Skills for 500 soldiers. Even the sergeant responsible for record-keeping outside had been replaced three times, yet Lu Lin hadn't stopped. His efficiency was high. While other Star Guides completed one person, Lu Lin could guide ten.</p>
