Beast Taming: My Brother Took My Place in the Army and Became a War God! Now He's Back to Steal My Merits?

[Beast Taming + Invincible Domination + Ruthless Battles + Cathartic + Takes His Brother's Place in the Army] Three years ago, Xu Mo transmigrated into a world where beast tamers reigned supreme and became a new recruit on the border battlefield against the beast tide. As the beast tide threatened the country, the entire nation began recruiting soldiers. To spare his younger brother from hardship, Xu Mo's parents forced him to enlist in his brother's place! Three years later, Xu Mo had slain countless beasts on the frontier and earned glorious battle honors! But when Xu Mo returned covered in honors and glory, his parents demanded that he hand over all his achievements! Their reason was that his younger brother had greater beast-taming talent, and exchanging Xu Mo's achievements for high-level beast-taming resources would let the Xu family soar to success! Only then did Xu Mo understand that, in his parents' eyes, he was nothing more than a tool to help his younger brother! He had enlisted in his brother's place three years ago, but this time, he would never make the same mistake again! Besides, could his younger brother even handle the honors Xu Mo had earned on the Northern Frontier battlefield? At the beast-taming talent awakening ceremony, his younger brother awakened the S-rank Beast Taming Talent: Berserk, earning everyone's praise. Xu Mo awakened a hidden SSS-rank talent, one unseen in a century, but everyone mocked him because he had received the cursed talent no beast tamer wanted: Bloodline Rebirth. The beast tamer uses their blood as a medium, merging with a blood formation to nourish their beast! Xu Mo smiled. He had awakened an undying body the moment he transmigrated! Undying Body: Immortal and indestructible. Even a single remaining drop of blood can instantly bring him back to life! It also comes with two stacked buffs! First, every time he revives, the Host's attributes, including vitality and mental strength, will randomly increase! Second, he's immune to all abnormal conditions, including pain and dizziness! They say cursed talents cost you your life? But what does that have to do with my undying body...?
