Correction
The young author just discovered that when uploading Chapter 678 - Super Mission Master, dozens of extra words were copied at the beginning... I'm sorry, it affects everyone's reading experience, and it has been modified now.
When the author comes back on the 19th, I will add more to compensate you readers.
Now that I'm out of town, I'm so exhausted that I can't add more for the time being. (End of chapter)
