The mural shows a man in armor standing in front of a group of people.
There are also countless flying unknown objects painted in the sky, each of which looks like a crescent moon.
"The Great Bell God?"
Lin Yu and Ban Lan looked at each other, with the same guess in their eyes.
This thing is the sculpture of the Great Bell God seen earlier.
The two of them then walked forward and came to the second mural.
What this mural depicts is a group of people boarding a flying object that looks like a crescent moon.
There is also a beetle painted behind each person.
Not surprisingly, this beetle should be a wild insect, so those people who board the flying objects are the aborigines of this world?
In other words, the world has also encountered changes.
But when there are even flying objects, why do we still need to paint murals?
Could it be that the technology here is a little bit crooked?
Lin Yu and the two then led many Zerg species forward and looked at the third mural.
The third mural shows the Great Bell God alone, holding a long sword in his hand, surrounded by the wreckage of fallen spaceships.
It seems that people in this world are fighting with certain people or creatures.
But they failed.
The fourth mural is the building of the Great Bell Church. The sculpture in the middle stands upright.
It was just like what they saw today, except that the building in the mural was intact, while the building in reality was already in ruins.
"I can't figure out what the meaning of this mural is. Is it trying to convey some information, or is it simply a record?"
Lin Yu was confused when he saw it now.
Then walking forward, there is the last mural, and then there is a door, a metal door embedded in the cliff.
This style is incompatible with blue-gray stone bricks and various buildings.
But the map points to the back of the metal door.
"There's something wrong with this last mural..."
Ban Lan looked at the mural on the ground with a solemn expression.
After Lin Yu heard this, he also turned his attention to the mural.
The fifth and final mural depicts two people with a swarm of bugs, facing a metal door.
That is their current behavior.
What is certain is that this painting points to them, the two insect queens, the King Insect and the One-horned King Insect, the flowers are particularly careful.
The large shield on Ban Lan's left hand and the long sword on his right hand are also drawn.
"Is this a prophetic painting?"
Lin Yu touched the marks carved by tools on the mural. It didn't look like it had been carved recently.
People in this world are so powerful that they can predict the future and anticipate their arrival, but they still fail to defeat powerful enemies?
How strong must the enemy be to defeat a race that can predict the future?
Unable to care so much, Lin Yu took out his mobile phone and took pictures of the mural, taking pictures from all directions.
Giving this thing to an association or scientific research institute can also be exchanged for a lot of points.
Later, Lin Yu and Ban Lan came to the metal door. The metal door was gray in color and had no handle or keyhole.
Getting in is a big problem.
But the road guided by the map is right here.
It means that the person who drew the picture has been in it.
Ban Lan took the long sword in her hand, inserted it into the crack of the door, and pried hard, but there was no reaction. Instead, her sword became bent.
"No, it can't be opened with brute force."
Ban Lan's strength is average for a four-star card master. Even her strength can't pry it open, let alone Lin Yu.
Lin Yu's head turned black as he looked at the king insect running in circles with its tail biting.
He quickly ordered it to use corrosive liquid to see if it could corrode the metal door open.
The giant king insect approached the metal door with thousands of legs and sprayed out a very long stream of corrosive venom from its mouth.
But the liquid that can corrode even the mechanical giants of Silver City has no effect on this door.
The king insect returned without success and retreated aggrievedly.
Lin Yu scratched his head, wondering how to open this thing. He took a few steps forward and observed carefully, only to find that the door was densely packed with various lines.
The door itself is white, but the lines are too dense and appear gray.
So if it is the same as the diary of Silver City, he can try to inject energy into it.
He put his hand on the metal door, and the energy in his body could be input into the door.
Soon, the entire door's lines were filled with blue energy, and from a distance, it looked like a blue door closing.
There was a squeaking sound.
The sound of metal friction came, and the metal door slowly moved to one side, revealing the environment behind the door.
The long and narrow corridor is clean and tidy inside, and it feels like two worlds inside and outside the door.
"It's that simple?"
Ban Lan couldn't believe it. He only needed to inject energy to open the door.
Lin Yu didn't explain too much about the reasons. Silver City Ban Lan didn't follow last time.
But he also had some doubts in his heart. Is the energy in the card master's body really omnipotent?
Any technological equipment in the rift can be opened using the energy in the body.
Let the Zerg go in first to test it out. When he found that there was no danger, he walked in first.
The route on the map still extends inside for a long time.
Ban Lan also followed behind and slowly entered it.
When all the Zerg entered, the metal door slowly closed again, and various unknown light sources lit up in the middle of the corridor.
The two of them walked along the corridor, and at the end there was a wide hall.
Several mechanical devices with unknown functions were scattered in various corners of the hall. Judging from the quiet state, they were not activated.
According to the route on the map, they need to go out from the double doors on the other side. After walking two paths, they will see the Zerg relics.
There is no energy supply inside. Except for the light source from unknown sources, all metal doors can be opened and closed with a simple push and pull.
Searching all the way, there are no abnormal creatures or dangerous mechanisms.
Soon, the two of them arrived at the end point recorded on the map, where the Heart of the Swarm was stored.
Lin Yu swallowed and opened the metal door in front of him.
In the empty room, on the table in the center, there is a round red sphere with several dark holes on it.
The moment they saw this thing, Lin Yu and Ban Lan understood that this thing was a relic.
However, neither of them acted rashly. The person who drew the map didn't take it away when he saw it, he just drew the map.
It means there must be a potential danger.
While Lin Yu was still looking at it, Ban Lan tugged on Lin Yu's sleeve and pointed to the ceiling above.
Lin Yu looked up and saw a giant black spider resting with its eyes closed on the ceiling.
Lin Yu sensed a strong deterrent from the black spider, which was definitely not a creature he could deal with at the moment.
He asked Ban Lan quietly, "Sister Lan, can you deal with this thing?"
"Yes, that is, four-star strength, similar to mine, but I don't know if there is any danger nearby."
Ban Lan scanned the room, and soon she found some egg-like things in some hidden corners, moving up and down, as if something was moving.
She continued: "As expected, this thing will summon the spiders in the eggs. It's up to you to deal with these little spiders."
