Avatar: Embers of Pandora

Kyle Vaughn, 7th Ecological Combat Brigade of the Federal Army, No. K-0719. His consciousness was projected into a three-meter-tall alien body - codenamed "Ember Spirit Body". Twelve interstellar expeditions, twelve planets turned into scorched earth, he is the Federation's sharpest knife and the most silent executioner. Mission Thirteen, Target Pandora-7, Black Level, Ecological Clearance, allows the use of scorched earth weapons. The moment the transport ship crashed, Kyle saw something that was never mentioned in the mission briefing - an alien sacred tree that reached the clouds and had a neural network, a breathing rainforest, and an alien girl Nitea who drew a bone bow in the sea of ​​fire. And a seed grew from the ashes and plunged into his heart. The sacred tree died, but its seeds chose the executioner's body and began to sprout. The roots spread along the blood vessels, replacing his heart inch by inch, turning him into the last weapon on the planet. The Federation wants to recover the seeds, the aliens want to regain the hope of the Holy Tree, and the blue light on Kyle's chest is getting brighter and brighter, and his body is being swallowed by the planet. Just when everything was out of control, Kyle remembered the erased memory twelve years ago - he had been here, saved a girl, and promised she would come back. That girl is Nitea. Now he's back, armed with sin and a sprouting planet. When the first heartbeat came from the scorched earth, Kyle had to make a choice: continue to be the sword of the Federation, or become the last shield of the planet.
