Tang xiu avoided clashing with other zombies and directly went for the 2nd stage Zombie to avoid wasting his stamina but it was impossible for tang xiu to avoid a army of zombies which seemed endless and while he was dealing with zombies other zombies tried to encircle him but the soldiers carefully fired bullets to stop the zombies from encircling tang xiu under the order of all of the high officers even so it didn't stop the zombies from encircling him so tang xiu had no choice but to use [Flaming sword art] after he used [Flaming Sword Art] it caused the sword to be on fire but the fire didn't hurt or burnt tang xiu
even a bit which made Tang xiu somewhat relaxed but it also made Tang xiu to pay attention to energy as using the art consumes 1 energy per second for using it but with the help of [Flaming sword art] it made more easier to kill the zombies
While Tang xiu was busy killing zombie he suddenly felt something then tang xiu barely doged the huge stone
Tang xiu enabled [Flaming Sword Art] immediately retreated while the soldiers stationed on the wall covered him
When Tang xiu turned back a zombie was laughing and tang xiu knew why he was laughing
Tang xiu clenched his fist and said "If this master can't kill you then from now on I would name myself dog"
Tang xiu immediately said in his mind
