Army at The Gate

"Brother Zhang, if you are willing to join our forces to defeat the Immortal Vampires, ten thousand lives of the Shi Family will be saved."

Shi Ren was touched and happy to hear that Zhang Ruochen was willing to fight against the Immortal Vampires alongside the Shi Family.

A friend in need is a friend indeed.

While Zhang Ruochen was not as strong as a Level Seven Half-Saint, he could kill the immortal vampires that the Level Seven Half-Saint missed out on. 

For instance, a Level One Half-Saint from the Immortal Vampires knew he would never defeat a Level Seven Half-Saint from the human race. Thus, he would escape the battle using a royal decree.

Once having escaped, the damage he could cause to the surrounding cities would be beyond imaginable. Thousands of mortals could die.

However, things would end up differently for Zhang Ruochen.
