Upon hearing the boom, everyone immediately turned their heads to look at the origin of the sound.
A large group of men were rushing over to where they were.
There were around 2000 men who were troops of the Black Mountain Fort. The man leading them, who was dressed in a silver coat, was Zhu Ying.
Beside Zhu Ying, there was also Deputy Commander Wang who was in charge of the mine.
Shoosh shoosh shoosh!!
Zhu Ying brought 2000 alpha troops and arrived at where the crowd was in a breath.
Looking at the Ren Yun Du as well as the Shen Wu Academy disciples unharmed and safe with their only loss a few men a suspicious flash passed through Zhu Ying's eyes.
"Where are the men from the Blood Pupil Clan?" Zhu Ying was the first to reach the ground and he immediately asked in a loud voice.
"We have caused them to retreat!" Ren Yun Du said.
"Already retreated? Are you guys alright?" A suspicious look was on Zhu Ying's face.
