After eradicating the troops of Outer Mongolia, Yue Zhong had gained a huge amount of resources. He made use of them to launch an assault in the direction of Hu He City.
The big-head Mutant zombie did not continue to harass Yue Zhong, instead, it summoned the zombies from Hu He City and made their way further northeast.
After collecting the 3 million zombies from Hu He City, the entire horde swelled to a size of over 4 million again.
Yue Zhong watched the horde advance towards the northeast, and although he was extremely worried in his heart, there was nothing he could do to impede them.
Yue Zhong had somewhat guessed that the commander behind this horde wanted to amass as many zombies as it could, before seeking him again. If the numbers were to exceed 10 million, then it would truly be a nightmare for humanity. This was what Yue Zhong was most afraid of.
