Star Dome Art of War: the Era of Decreasing Entropy

Sun Che came to Qingqiu Star not to fight. Three months ago, his student Chen Mo died here. There were only three words in his last words: "They are -" The Federation said it was an attack from the Bamboo tribe. Sun Che cracked the second half: it's not "attacking", it's "breathing". The bamboo tribe is not the enemy. The bamboo tribe is the planet itself. They think with roots, remember with telepathic particles, and use three million years of war trauma to identify friends and invaders. Any human who comes close will be penetrated by them within 0.3 Seconds - that is not an attack, but an immune reflex.
