The team leader must hold the Shield, because the person holding the Shield needs to have a strong physique first and foremost, but even more importantly, they must possess extraordinary courage; otherwise, they wouldn't be able to bravely confront the oncoming zombies.
So Zhang Zhe was the one holding the Shield, while the other Shield was held by Li Xiaodong.
Gao Yuan and Ma Zihang each had a long knife, then Li Changfeng took up an axe.
Why must there be someone with a short weapon? Because when entering a house, the Shield bearer goes in first, followed closely by the axe-bearer. Only after these two have entered do the long knife wielders follow suit.
In fact, it is only in the moment of entering that the axe-bearer is necessary, but until a better method is found, this role of the short axe wielder will continue to exist.
