There are barely any spirit beasts left on the planet, since they have been relocated to the Elven Planet and Forest Luo Planet. The Douluo Continent was replanted with countless plants and flowers, improving the environment and the quantity of life energy on the Douluo Planet. The Continent was almost destroyed during the second invasion, but thanks to the ten thousand year planning by Tang San, the Eternal Tree was able to absorb the life energy from the Abyssal Plane, causing the Douluo Planet to evolve and allow spirit masters to cultivate beyond rank 99. The Continent faced a life crisis during the first invasion. This lead to the Abyssal Plane and other planes attacking the Douluo Planet. If this continued, the continent would have been destroyed. With the rapid development of humanity, spirit beasts are on the brink of extinction and the natural resources on the continent are being depleted, causing the environment to deteriorate. It's because of this that the Douluo Continent has the most number of spirit masters. It is home to a wide variety of spirit beasts and different natural environments like the extreme northern lands and the Star Dou Forest. The most noteworthy are Shrek Academy and the Tang Sect. Fortunately for me (and probably many other fans), I learned very quickly that The Master’s Sun is rich with humour (including many laugh-out-loud scenes), scares and genuinely heart-warming moments that endear the viewer to each and every character written and brought to life by the talented Hong Sisters, and the incredibly well matched cast. It was the home of many kingdoms and empires as well as many different sects and schools. Before the events of SL2, the Sun Moon Continent collided onto the Douluo Continent, linking the two continents. It is the largest out of the present three continents.
The other one being the Sun Moon Continent. The Douluo Continent is one of the two continents that humanity was born on, on the Douluo Planet.
