The Boiling Sea.
At a depth of roughly 300 meters.
A giant Long-Legged Sardine moved through the water here, kicking hard with its four long legs while swinging its tail, trying to dive deeper.
"This is as far as we can go."
Yang Yi glanced at the water pressure gauge. Its needle kept trembling, but it was still within the safe range.
However, this was the deepest the Long-Legged could dive. Any farther down, and the rising seawater would push it back up. Even the Great Sea Lung Jet was no help; it would descend a little, then rise again.
So a depth of around 300 meters was the Long-Legged's limit, at least in the Boiling Sea.
To move freely underwater, it would have to stay even shallower, probably rising another 100 meters to a depth of around 200 meters.
"The heat is coming from below.
"The deeper we go, the more violently the seawater churns. There are also large amounts of gas mixed in, all in the form of extremely hot bubbles."
Su Na was also in the cockpit, looking outside as she observed and recorded the conditions in the deep sea.
The demonic Anglerfish lantern they had obtained earlier proved extremely useful now. The Long-Legged had no exterior lighting, and its eyes only let light through in one direction, so the lantern became an effective source of illumination. Not only could it withstand high temperatures, but it could also provide continuous lighting. It had already been mounted above the bow cannon.
Otherwise, an ordinary person here would have been completely in the dark, unable to see a thing.
Moreover, the sonar system was useless in boiling water. Noise, currents, and bubbles all interfered with sonar.
Otherwise, Xiaoji's onboard sonar system could have played an important role right now.
