The sound of rustling and crawling sounds all around gradually faded away.
Elena returned to them and whispered that if the linguist brought to the Wiener Dungeon might be able to understand what she said.
Lu Li roughly guessed what she said and told the others: "They were lured away by Elena."
Relaxed gasps came one after another, and they held their breath in order to be quiet and listen.
A line of footprints extended to Elena's side, her tentacles raised, and then Lu Li's voice sounded.
"It's not safe here, let's go back to Whirlpool Town first."
Other footprints followed, and Langer's voice sounded: "What to do with these footprints? They will reveal our location."
Lu Li swept across the disappearing footprints under the breeze: "The wind will help us bury the traces."
The invisibility potion lasts about 15 minutes, and Lu Li's in Doomsday Apocalypse lasts for 30 minutes, but it is of little use.
A few minutes later, they stopped at the edge of the forest, looking at the eerie and strange whirlpool town in the distance.
Unfinished houses, empty streets, and cookie-cutter longhouses all form a maze that seems to have no end.
The search for the Vortex Man gave them the opportunity to return to the Vortex Town. Elena led the invisible people to avoid the Vortex Man and hid in a vacant room outside.
The dusty floor indicates that no one has lived here for a long time.
What is disturbing is that the swirling clouds that appeared in the sky due to the invasion have not disappeared, slowly spiraling clockwise around the towering tower.
Lu Li looked through the back window at the outskirts of the Whirlpool Land. They were right to leave. The Whirlpool Man was searching along the fog wall repeatedly. But because they left fast enough, the Whirlpool Man couldn't even find their footprints.
Footsteps sounded from behind, and Langer walked over with a piece of linen cloth, and suddenly bumped into Lu Li, who was still invisible.
"Sorry Mr. Lu Li, I didn't know you were here." Langer's reaction was as fast as his speaking speed.
Lu Li quietly stepped back to make room, and took out a bottle of potion from his stomach bag, letting others see the floating potion and know he was there.
Langel successively hung curtains on the back and front windows to block possible prying eyes, and returned to a much darker house.
"Mr. Lu Li, what should we do next?"
He and others looked at the suspended potion bottle, and then saw a notebook and a pen floating in the air, leaning against the dining table.
Tris, who was sitting in the wooden chair, quickly stepped aside, watching the notebook open, tearing out a blank page, and writing on it with a pen.
"Tell the Twisted Shadow what happened here."
Lu Li wrote down the situation in the Whirlpool Land, and at the same time told his companions about the two plans: waiting and attacking.
Wait for the Twisted Shadow to rescue and attack the Spiral Tower.
The exorcists had some disputes over their plans, and most chose to wait, but Porter and Langel thought they should attack the tower, and Elson joined them after hesitation.
In the hushed discussion, Lu Li finished writing the letter, opened the eyeball wooden box and summoned the merchant Anthony, but it did not appear.
Maybe he was judged as "ownerless" by the merchant ritual because of his invisibility?
Lu Li asked Porter to summon him, but he opened the wooden box and after a few minutes, nothing happened...
The exorcists were feeling vaguely uneasy. Rather than the "eyeballs" losing their function, they speculated that the isolation of the Whirlpool Land was not blocking out the one-way merchants.
This situation has never happened.
No matter the era of the Demon Slayer Association or the strange era after Lu Li's awakening, the dark age.
Merchants moving in the other world will almost never be blocked, unless... the obstruction originates from the other world.
Lu Li opened his stomach bag again and took out a bottle of potion filled with black mist.
"Latent image potion...? Please wait a moment, Mr. Lu Li!" Potter stopped Lu Li's relief: "Do you want to enter the other world to observe?"
"Um."
"That might be a little dangerous, leave it to me."
The danger comes not only from the other world, but also from the medicine itself. All medicines are contaminated, especially sequence medicines.
The existing record of Giant Tree Academy is that a student suffered from irreversible true low sanity syndrome after drinking ten serial potions.
But that is continuous, and maintaining a long enough interval can minimize side effects.
Porter took the latent image potion instead of Lu Li, and his figure gradually dimmed, even more completely than the invisible Lu Li.
The latent image potion would last no more than three minutes, and they began to wait. In the second minute, a pale Potter fell out of the corner.
"The other world is also like this..."
Potter rushed to the window and raised the curtains to confirm something, but his next words made everyone unable to think.
"Those whirlpool people are also in the other world!"
The other world is like ghosts, evil gods, evil spirits, weirdness among weirdness; occultism among occultism, alchemy, and divination. It represents individual things and is also a general term.
The collective term refers to "all inner worlds except the apparent world under your feet", such as the inner world of businessmen and the inner world of earth dwellers.
The other world usually talked about is the other world of ghosts.
The world in the ghost is like a reflection in a mirror, the reflection on the water is the shadow of the real world.
Part of the reason why the Demon Slayer Association once classified ghosts as "they are the successors of humans, not replacements" is that they were once humans, have memories of when they were humans, and live in the projection of the world of representation.
Ghosts obey the "rules of the other world": when they appear in reality, the other world is no longer there. When they return to the other world, reality is no longer there.
Ghosts cannot appear in the real world and the other world at the same time. The news that Porter brought back is that the Vortex Man is in the real world and also in the other world.
Perhaps this is why the merchants are unable to respond to their summons. The Whirlpool has taken control of the underworld.
In any case, it has become an established fact that they have lost contact with the outside world, and the rescue they relied on cannot help them for the time being.
The panicked exorcists looked at Lu Li, waiting for the legendary exorcist who had never failed to make a decision.
"The third way."
The invisibility potion expired, and Lu Li slowly emerged from the wooden chair in front of the dining table: "Collect clues from the Whirlpool Land and wait for the Twisted Shadow to react."
That will be the time for them to really take action, whether it's to respond to the twisted figure or to attack the tower.
Lu Li took out two bottles of sleep potion. Elena should know many secrets of the Whirlpool Land.
At this time, Elena is no longer just a rescue target, but also a companion who provides help.
Lu Li and Elena took the potion and entered the dreamland, while the remaining ten trainee exorcists were waiting and observing the outside.
Langer pulled out the dagger at this moment, and Elson next to him drew a line of blood along the ridge on the back of his hand in surprise.
"What are you doing?" Potter frowned.
"Don't you think that eleven exorcists broke into the Forbidden Land of Despair and everyone returned smoothly after overcoming obstacles?" Langer pressed the skin with trembling fingers and squeezed out the blood-wrapped pendant. His words made his companions feel strange but not surprised:
