Rebirth: King of Special Forces

In his past life, Lin Chen was the top soldier-king of the Fierce Tiger Special Operations Brigade. During a mission abroad, he stayed behind to cover the retreat and was buried in the jungle. He opens his eyes and is reborn back in 1984, just in time to run into his fiancée bringing a small-town playboy to his door to publicly break off their engagement! Everyone thinks he is just a cowardly, dull country youth. No one knows that inside this body lives a special-operations veteran who walked out alive from mountains of corpses and seas of blood! The God of War Military System activates, and the sealed battlefield memories of his past life are gradually unlocked! The playboy publicly declares he will block his military eligibility? One grappling move slaps him in the face on the spot! Troublemakers in the recruit camp gang up to provoke him? He crushes everyone in every assessment! Recruit training, military region competitions, border infiltration missions, international special forces tournaments... Cutting through thorns and thistles all the way, his chest is covered in medals! Those who once looked down on him can only raise their heads and look up! Starting as a small-town youth whose engagement was publicly broken off, he charges through blood and fire to reach the top as the king of soldier-kings! — Description from novelcodex.orgFull novel: Rebirth: King of Special Forces — read the rest free on N​o⁠v​e⁠l​C⁠o​d⁠e​x⁠.​o⁠r​g⁠
