Explode the Mission System and My Mother Will Live a Long Life

Bai Ze was a staunch atheist until his mother was critically ill and he accidentally discovered that the pendant left by his father was actually a Tianzhu inheritance. From then on, he walked in the world of immortality with thousands of races and monsters, and exchanged his mother's life with narrow escape missions. While others compete for the position of genius and opportunity, he only fights for a slim chance of survival. Others asked for immortality, but he only asked the people on the hospital bed to call him Ozawa one more time. The dangers in all the worlds were not as important as his mother's life in his eyes.
