Originally, General Shang brought so many people today to show Ruan Chao'en that they had also been doing well during his absence, to put his mind at ease. However, this could also alert those with deep schemes that they were indeed hiding something.
The soldiers didn't want Ruan Chao'en to do anything irrational again. At Gujin Base, it was still manageable since it was far from the Emperor's reach, and killing a few careless fellows could be concealed if one was determined.
But here, when Ruan Chao'en killed three people in a fit of rage, it was already the greatest tolerance that the Marshal did not execute him as a warning to others. If it happened again, it might not be as simple as being jailed, as no one knew what the Marshal might think during a particular time.
The atmosphere among the crowd solidified, and Ruan Chao'en became more certain of the thoughts in his heart. Something significant indeed happened during his absence.
