This was done probably because the tribes did not want other tribes to steal their fragments.
However, this gave Wei Xiao Bei a reason to not fear being noticed by other tribes when he stole it.
The tribe that Wei Xiao Bei initially infiltrated had twenty wooden houses. According to his count, there should be ten Einherjars in each. This was most likely a small tribe of only two hundred people.
Because the majority of the Einherjars had joined the war, only four Einherjars were guarding the central house.
Wei Xiao Bei did not hesitate. He moved on all four limbs like a leopard slinking through the grassland. As he passed through the houses, he quickly reached the central house.
The Einherjars were also quite vigilant. Even if Wei Xiao Bei had been at his quietest, there was still an Einherjar that noticed it.
