I drilled into it for more than a dozen stops in a row, and there were several dangerous places on the way.

Trap pits, poisonous pools, spikes, and poisonous arrow walls are all terrifying for ordinary people. However, for Jia Zhengjin, accidentally stepping on the trigger plate, a teleportation can allow him to avoid all dangers.

It really doesn't work, he can still flash directly to get over the trap. At most, I was a little scared on the way, but my life safety was guaranteed.

Just when he felt that it seemed endless, finally this time the end was no longer the small room with the coffin.

The room was empty, with no coffin or another passage. Only a heavy stone door stood in front of me, and there were several abstract patterns on it.

"What is this?" Jia Zhengjin approached the stone gate, illuminating the torch close to the light and observing it carefully, "Kindergarten children's graffiti?"

In the center of the stone door is a disc-shaped object, surrounded by six strange holes, each corresponding to an abstract graffiti.

The six graffiti are too abstract and look a bit like animals in outline.

He couldn't figure out exactly what the animals were, so he could only use their characteristics to temporarily name them snake patterns, fish-shaped patterns, bird-shaped patterns, bear-shaped patterns, pig-shaped patterns, and turtle patterns.

You really want to say that they are snakes, fish, birds, bears, pigs, and turtles, but they are not the same except for the slightest resemblance. It is estimated that it is a sketch of some otherworldly creature, but the person who paints it is really limited in skills.

But he also admired that these patterns were chiseled out of the stone little by little. I dare to put such an ugly painting on it, and I am too confident!

There was no switch around the stone gate, and Jia Zhengjin searched for it several times, but it was empty.

The only thing that catches people's attention is the disc in the middle of the stone gate, the small holes and patterns around the disc.

Could this be the switch, right? Jia Zhengjin curiously stretched out his hand to turn the disc, but found that it did not move.

To get through here, you'll need to find the six keys and arrange them in the correct order.

The system prompt rang at the right time, telling him that these six small holes were keyholes.

"Do you need to be so troublesome?" Jia Zhengjin rolled his eyes, and immediately took out the legendary quality pickaxe from his backpack and knocked on the stone door.

Since this is a sandbox game system, everything should be destructible!

I thought so, but when he did it, he realized that it was not that simple.

【System】The goal is invincible!

Jia Zhengjin was speechless, and tried to dig the bricks next to him, but the result was the same prompt. It was impossible to dig a path from any one place to the back of the door.

"Do you mean I can only obediently look for the key before I can enter?" Jia Zhengjin said in his heart that it was too troublesome, but he had to go back the same way.

Saying that, along the way, he was looking at the soles of his feet, and he really didn't pay much attention to the side.

This time, I didn't let go of any corner, and after trying to find it, I finally found that among the clay pots everywhere, there were several of them engraved with the same pattern as on the stone gate.

The first one he found was a clay pot carved with a "snake pattern".

But he had already searched the clay pot once, and the second search was nothing!

Could it be that the key has already been taken away? Then the system shouldn't trap me! Jia Zhengjin circled around the clay pot a few times, thinking about it, he felt that the system would not pit itself, so he carefully searched around the clay pot.

After rummaging through the pot, I accidentally removed the clay pot and noticed that the soil underneath was slightly different in color from the surrounding one.

Isn't it going to be buried under this? But isn't this tomb all invincible?

He hesitated for a moment, then tried to build a stone shovel and dig into the ground.

I didn't expect that unlike the surroundings, the soil under the clay pot alone is destructible!

Sure enough, when he dug down three squares, he found a rusty metal key.

This key is also engraved with a long, coiled "snake pattern".

You can dig down here, can you dig through?" Jia Zhengjin tried to continue going down, but found that in addition to the three squares just now, it also indicated that the surrounding terrain was invincible.

Surely, you can't use it, so let's keep looking for the key honestly!

But how can there be a string of generalized characters from the other world on the key of this snake pattern?

Although Jia Zhengjin can speak the common language of the other world, he does not have a good grasp of words. After all, I only drank the primary knowledge potion, and the knowledge I got was limited. Therefore, he only vaguely recognized a few of this line of text, and if they were combined, they could translate a morning, and the others were completely blind and incomprehensible.

That's no problem, just go on.

I searched all the way back until I reached the original room and found all six keys from under the clay pot.

Each key corresponds to a pattern, and it also has very, very small text. Jia Zhengjin recognized only the simplest words: "morning, sunset, night, scorching sun, noon, sunrise", and nothing else.

I took the key and came to the innermost stone gate, and I was entangled.

It needs to insert the keys into the keyhole one by one in order, and it needs to be corresponding, so that it cannot be inserted in the wrong position.

But there is no one, two, three, four, or five on the key, how does he know which is the beginning and which is the end? You must know that there are so many arrangements of the six keys that they cannot be opened unless they are tried one by one and spend a lot of time foolishly making them together!

Jia Zhengjin tried to insert the key casually, but it didn't work at all.

"It's just a random task, does it need to be so difficult?" Jia Zhengjin was depressed, and stared at the six keys in his hand for a long time, and thought about it for a long time. Later, I couldn't think of anything, so I simply used this method to start making up one by one.

But after a long time, I still can't get this sort out.

"Am I so stupid?" Jia Zhengjin, who was deeply shocked, was almost driven crazy by the order of the keys.

Don't look at the fact that there are only six keys, but no matter which key is the first, there are countless possibilities for the next order. Such a stupid method of figuring out the real order really takes a lot of time. It's not just an hour or two, and if you're unlucky, you won't be able to do it for a day or two!

Sure enough, the order still has something to do with these words, right? Jia Zhengjin was so annoyed that he finally turned his attention to the words on the key. But he only knew a few simple words, and he couldn't read the whole sentence at all!

Staring at the key in a daze, his mouth kept repeating these six only words he knew, and he didn't know how many times he repeated them.

I don't know what's going on, but a flash of inspiration suddenly flashes in my head: "Wait! I seem to understand!"
