A person who has traveled all over the green mountains is still young, but when he suddenly looks back, the sword is just between his eyebrows, but in his heart. Jing Jiu, who lives in a mountain village in Chaotian Continent, unexpectedly receives Liu Shisui, who is born with Taoism, as a book boy. The two came to the Qingshan Sect by chance, but they were criticized because the mediocre Jing Jiu actually took the extraordinary genius Liu Shisui as his servant. At the sword inheritance conference, Jing Jiu also met Zhao Layue, a Sanwu girl from Shenmo Peak. Jing Jiu, who is surprisingly lazy, just wants to practice quietly, but little does he know that fate will involve the three of them in a huge river and lake dispute... Under the Taixu, are the green mountains far away? Not far. (Source: Bilibili, Google translated)

Second season of Ling Long.

After the destruction of their hometown, childhood friends Kafka Hibino and Mina Ashiro make a pact to become officers in the Defense Force—a militarized organization tasked with protecting Japan from colossal monsters known as kaijuu. Decades later, the 32-year-old Kafka has all but given up on his dreams of heroism. Instead, he cleans up the remains of the slaughtered kaijuu after they are defeated by valiant soldiers—including Mina, who has successfully achieved their shared goal. Upon meeting his new coworker, Reno Ichikawa, Kafka faces a mirror of his past self: an ambitious young man whose one desire is to fight as a member of the Defense Force. Unfortunately, the two are soon involved in a freak encounter with a rogue kaijuu. Though Kafka demonstrates his innate heroic nature and rescues Reno from certain doom, he is left gravely injured. While both men recover in a hospital, Kafka is seemingly attacked by another one of the beasts. As a result, he gains the ability to transform into a humanoid kaijuu with the strength and powers of the massive monsters menacing Japan. Dubbed Kaijuu No. 8 by the military, Kafka resolves to use his newfound gifts for the greater good. Tied together by mutual respect, Kafka and Reno set out to join warriors like Mina at the forefront of the Defense Force.
