There are many dense holes on the cave walls on both sides of the stone wall, and tiny water lines flow silently from the holes.

All water lines converge and fall to the ground, turning into a small stream that winds out of the cave.

Standing in front of the black stone wall at the end, Yu Hong held up the atomic lamp and illuminated the five-meter-high wide rock with green light.

On the stone wall, a huge round arch was clearly drawn in gray handwriting.

This painted door is densely engraved with many unknown symbols and characters.

Yu Hong quickly found several symbols used in the pyroxene runes among these symbolic texts.

He suddenly became energetic, put down the stick, took out a pen and paper from his pocket, and carefully copied down all the symbols that appeared on the door.

Including the symbols from the murals on both sides when walking in from the outside, excluding a large number of repetitions, he copied a total of seven.

But after repeated copying, Yu Hong faintly discovered that these seven symbols not only formed the pyroxene runes, but also formed another more complex large symbol on the mural door at the end.

This large symbol appears frequently in the area above the door of the mural. The strokes are sharp and powerful, but I don't know what it does.

After Yu Hong finished copying, he always felt that the big symbol was a bit strange.

At first glance, it looks like a moving whirlpool. But upon closer inspection, you realize that what you just saw was just an optical illusion.

‘Why didn’t the outside explorers study this symbol? Instead, they only studied the pyroxene runes?’

He doesn't understand.

After the transcription was completed, he searched around the corners for a while and made sure that nothing else was found. All the original furnishings had been dragged away long ago, and he had no choice but to exit the ruins cave.

It was slow when he entered, but much faster when he came out. It only took a few minutes for Yu Hong to stand at the door of the cave again.

‘The runes on the pyroxene are called amplification runes. This newly discovered rune symbol is temporarily called the swirl rune. I hope there will be new discoveries’

Feeling a little disappointed, he looked back at the ruins cave.

'Did the first black disaster really escape from a place like this?'

He recalled the frescoed door at the end that he had just seen. The characters carved on the door, apart from large sections of unknown words, were the pyroxene amplification runes and the newly discovered swirl runes.

It's just that some of the runes on these stone walls are elongated and deformed, some are reduced, some are square, and some are like dough being flattened.

With doubts in his heart, Yu Hong quickly returned to his residence.

He planned to use the black seal to quickly study the function of the swirling runes.
