Unfortunately,
due to the presence of fire.
The intense high temperature is enough to destroy any scientific instruments.
Therefore,
the only "safe zone" they can be sure of
is only a kilometre away from here.
As for what lies beyond, Chen Sheng and others can only rely on their own exploration.
That being said,
Li Wuji's figure turned into a black thread, rushing towards the tunnel in front.
The three men followed closely behind.
A distance of one kilometre is not long for them.
Especially when there are no other abnormalities confirmed.
In just a breath's time,
the four top-tier transcendent beings had already reached the previously explored boundary.
However,
even advancing a kilometre, there isn't much change in the scenery within sight.
If there's anything different,
it's the flame's color.
Chen Sheng noticed keenly,
in comparison to the bright red flames a kilometre away,
the hues he saw now were somewhat lighter.
