I Pretended to Be Invincible at the Beginning and My Defense Was Broken.

I'm a newbie, so please bear with me if I have some shortcomings. The protagonist is a bit funny. He is not invincible in the early stage. In the middle and later stages, he becomes invincible when he builds up his power. The system will change later (it will change in Chapter 27). Chen Dihao traveled through time, came to Tianwu Continent, and obtained the system. However, as time passed, Chen Dihao discovered that this system was not invincible at all. Invincible? Bah, fake invincibility. Just when Chen Dihao was disappointed, the system was surprisingly recovered and a new system was obtained. The dragon can be big or small, it can rise or disappear. If it is big, it can stir up clouds and spit out mist. If it is small, it can hide and hide its form. If it rises, it can soar in the universe. If it is hidden, it can lurk in the waves. The dragon rides on the changes of time, which can be compared with the heroes of the world.
