As soon as he entered the corridor, Zhang Ning felt light, as light as a swallow like Kakarot who had removed his weight-bearing training equipment!

He then retracted the acrylic bricks, and was half as easy again, slowing down the "Aura Consumption Progress Bar" by a total of 34.

The water temperature here is not very high, only seventy or eighty degrees.

Zhang Ning swam through the many roads that crisscrossed the city, adjusting the direction of the water temperature several times in between, and finally entered the hot geothermal lake.

The scenery in the geothermal lake is completely different from the slime lake, and the inky black bottom of the lake has countless small raised pores bubbling like well-behaved pimples.

The water here is also black, and the demonic mist has also eroded on the side of the geothermal lake, which is mixed with demonic liquid.

Zhang Ning hurriedly raced against time to collect several rare resources:

A few green aquatic plants - green that can still maintain vitality in such a harsh environment must be a treasure;

A fist-sized piece of amber with an eyebrow-squeezing mushroom in it. This is a precious ancient mushroom essence, looking at the appearance does not belong to any of the seven kinds of mushrooms, and it seems to be still alive, maybe the mushroom ancestor can be coerced in the future to order the humming clan;

Several lumps of foam - high-density foam formed by condensed bubbles, which are similar in composition to natural gas, and may be used as earth bombs.

It took Zhang Ning a whole night to dive to the "outlet" of the geothermal lake, where the temperature was extremely high, maybe four or five hundred degrees, maybe connected to the underground volcano, in order to support the protective barrier, his aura consumption has become a lot larger.

Zhang Ning, who was wearing an invisibility talisman, quietly poked his head out of the boiling black lake water.

The walls of the cave were all pitch black, and there was no sound in the cave, and even the sound of boiling water in the lake was extremely weak.

The cave is long and narrow, with bat-like "flowering" wings hanging from the ceiling, and a drill-shaped head with long ears comparable to that of rabbits, and giant teeth dripping with salivation...... Their saliva drips on the ground silently......

Why do mushroom spirits call them fireside bats? Obviously it's dark......

Zhang Ning held his breath and landed on the shore of the lake, trying not to stir up a trace of aura fluctuations.

The rock beneath his feet was hard and blackened, full of holes, a bit like volcanic rock, and the whole cave was filled with the smell of natural gas - was the demon bats hanging on the roof of the cave so quiet for fear of sparks if the noise was too loud?

According to the demon mushroom's guidance, the end of this cave is connected to the place where the treasure is located.

There was no abnormality for the time being, Zhang Ning tried to take a step forward, and the demon bats above his head lit up at that time - small red flames ignited on the edges of the fungus-like wing membranes, which made their wings as bewitching as black velvet with red silk edges!

How did they find Zhang Ning, who was holding his breath with an invisibility charm, and did he rely on the monster's sixth sense?

However, the fireside bat still did not attack Zhang Ning, but only drooled seriously.

Maybe that's what the protagonist's aura does - once again, I miss the "protagonist aura," an additional part of the golden-edged goblet. ”

Zhang Ning walked quietly in the passage, lighting up the cave step by step - everywhere he walked, the bat by the fire would light up, like the induction light band in the starship.

Zhang Ning didn't take the initiative to attack with his hands cheaply, maybe people are just sensor lights?

In this eerie red glow of serenity and enthusiasm, he came to the stone gate at the end of the passage.

An ordinary stone door, without any decoration or texture, smooth and flat like an artificial stone.

Before Zhang Ning could study the mechanism for opening the door, the stone gate suddenly fell down with a "bang" without warning, like the sound of a papaya falling into the water.

Zhang Ning was instantly ready for battle.

...... And yet nothing happened.

There were no red-hot and fiery fire-side bats rushing up behind him, and there was no black rumbling black demonic mist rushing out of the door.

Zhang Ning expanded his divine sense, and the roof and ground of the second tunnel were all pitch black as before, and the walls of the cave were covered with black lizards like coal.

He cautiously stepped inside the door.

The tails of the coal lizards on the walls of the surrounding caves lit up with red fire.

They had two manes like rabbit ears, and their heads dangled like drill bits, and they salivated at Zhang Ning while sliding......

Well, this time it's a wall lamp.

After lighting up all the coal lizards in turn, he came to the second stone gate, and a similar scene appeared - the stone gate fell with a "bang", opening his black hole to him.

Zhang Ning cautiously probed into the third path with his divine sense, and then ...... Flew in.

The roof of this corridor is pitch black, and the ground is densely packed with black demon frogs.

Their drill-like heads protruded a black tongue on each side of their heads, writhing and mischievous.

Just like before, as Zhang Ning flew forward, the demon frog below opened its big mouth and lit up its entire head while drooling.

Therefore, as Zhang Ning flew, black "candles" gradually lit under his feet.

This atmosphere is neat, and a little romantic.

After lighting up all the little monsters in the three corridors, Zhang Ning came to the third stone gate.

This stone door is of the same size and material as the first two, but in the middle of the third stone door there are two keyholes—a circular groove the size of a baked cake and a spherical groove the size of a thumb.
