According to the secret realm information provided by the City Defense Office, there cannot be any light in this dark passage leading to the second floor of the mine, and one can only move forward in the dark. Otherwise, it will cause some unknown dangers, including but not limited to mine collapse, ground subsidence, ghosts that can travel through rocks, etc.

This slope passage is not long, only 120 meters. If you run with your eyes closed, you can pass through it in ten seconds. However, if you can stay in this slope passage for more than five minutes, there is a certain chance of obtaining a temporary "dark vision" effect, which can last until you leave the secret realm.

In order to save lighting tools, some miner apostles would stay here for five minutes as soon as they entered the mine to obtain temporary effects before going back to mine. This way, they would not need to consume lighting tools such as candles, torches, and mining lamps.

Xu Feng entered the sloped passage, walked about two or three meters and then stopped, waiting patiently. Just after three or five seconds, he heard the roar of a dog-headed man coming from the first floor of the mine.

"The monster has been refreshed..." Xu Feng's mind moved, and he wanted to go back and hunt the Kobold Miners. The main quest required thirty Kobold Candles, but not every Kobold Miner would drop them. If you want to complete the Bend Sinking quest, you must kill at least thirty-five or even forty Kobold Miners. If you are unlucky, you may not be able to collect all the quest items even if you kill forty.

Just as Xu Feng stood up and prepared to return to the first floor, the ogre's roar quickly turned into screams, and finally gradually became quiet.

There are at most a dozen or twenty Kobold Miners spawning on the first floor each time, but the number of mining apostles is five or six times that of them. There is a chance that ore will drop when killing Kobold miners, and the purity is very good. Occasionally, top-quality ore with a purity of more than 20 will appear. In the eyes of mining apostles, these Kobold miners are not only a diversion in the boring mining process, but also a kind of existence similar to scratch-off prizes. Once they are refreshed, they will naturally be scrambled for with great pleasure.

Xu Feng had just taken a step forward, but he retracted it and stayed obediently in the dark passage.

Five minutes later, Xu Feng suddenly felt his eyes brighten. The slope passage, which was originally pitch dark, gradually became clear, as if it was wearing a filter.

Xu Feng stood up and continued to walk towards the second floor of the mine. The slope passage was not a straight line, but rather meandered downwards. If one really rushed straight ahead blindly, one would most likely hit the rock wall and bleed.

Xu Feng walked to the middle of the ramp and found a mine car, tilted on the side of the track. The mine car looked very old, but the four concave wheels were very new, as if it had just been pushed off the track.

Xu Feng walked up to it and walked around the mine cart. He always felt that there was something strange about this tilted mine cart, which gave him a weird feeling.

Xu Feng walked around to the side of the mine cart, pressed the edge of the mine cart with both hands, and exerted force suddenly. The mine cart weighing more than 100 kilograms began to move slowly.

Soon, the concave wheels on one side of the mine car were blocked by the ground track. Xu Feng lifted the mine car with both hands, and the four concave wheels were stuck on the ground track.

"Huh, this mine cart is heavy enough. If I want to straighten it, my strength attribute must be at least ten points." Xu Feng thought to himself.

If other secret realm apostles saw this tilted mine cart, they probably wouldn't even take a second look at it. Only Xu Feng, who had the memories of his past life, would be like an obsessive-compulsive patient, tinkering with anything he saw as wrong.

In most cases, this kind of behavior is like mental illness, which makes people feel strange and useless. But occasionally, one or two times when it works, Xu Feng can make a lot of money. Therefore, Xu Feng has always enjoyed doing this little thing.

"Isn't this how the clue was discovered?" Xu Feng looked at the original position of the mine car, where a silk handkerchief appeared, and a smile appeared on his face.

Xu Feng didn't care at all that the handkerchief was covered in dust and was already filthy. He unfolded the handkerchief and saw a dark red mark in the middle. Although a long time had passed, the dark red mark had already soaked through every thread of the handkerchief and looked shocking.

On one corner of the handkerchief, there was a pattern embroidered with golden silk thread. Xu Feng knew that this was the family icon, indicating that this handkerchief was an item of this family.

Generally speaking, such items embroidered with family icons cannot be discarded at will. Even if they are not used, someone must be responsible for their destruction and they will not be circulated outside.

Xu Feng turned the handkerchief over and over for a long time, but he only found the family icon and the dark red stain in the middle of the handkerchief that looked like blood.

The next moment, the Apostle Mark on Xu Feng's chest suddenly emitted a burning pain. The feeling appeared quickly, but also disappeared quickly, lasting only about a second, as if it was specifically reminding Xu Feng.

Focusing his attention on the apostle mark on his chest, Xu Feng soon had a message prompt appear in his mind.

[You get the clue item "Bloody Handkerchief". On this handkerchief, there is the family emblem of the Roman family embroidered. Please take this handkerchief and take the mine cart to the second floor of the mine. Find the steward of the Roman family and ask him about the information contained in this handkerchief.]

"Hidden mission!" Xu Feng clenched the handkerchief tightly in his hand.

Following the mission instructions, Xu Feng climbed onto the mine cart. At this point, he was only thirty or forty meters away from the second floor of the mine. Even if he walked, it wouldn't take much time. But since the mission required him to take a mine cart to the second floor of the mine, Xu Feng didn't want to create unnecessary trouble.

There is no wrong version in the 1619 book forum!

The rewards for hidden missions are very good, and can also improve your clearance rating. It is not difficult to complete them, but it is very difficult to trigger them. It is difficult for ordinary people to get clues to hidden missions.

Just like this overturned mine cart, this level zero secret realm has appeared for almost two years. There are at least eight hundred apostles who have entered this secret realm, but no one has tried to lift it up.

It was originally a trivial matter. The only hidden condition was that the strength attribute had to be more than ten points to lift up the mine cart. For the miner apostles, this was nothing. What was more difficult was probably the "darkness under the lamp" mentality. Most of the apostles, seeing this tilted mine cart, would subconsciously treat it as a "background map" and would not care.

Xu Feng jumped onto the mine cart, grabbed the joystick and pushed it forward hard. There was a sharp "creak" sound, and the mine cart shook violently, then began to move slowly, heading towards the second floor of the mine.
