His feet hit the ground, and the light on his body dissipated.

If it weren't for the key, I'm afraid that entering the space inside the city from outside the city could easily shred up any living thing.

Zhang Chen looked at the former city curiously.

Looking around, the former city is not so much a place for ordinary people to live, but more like a fortress of war.

The dome above is blocked and unattainable.

The building is like a forest of steel, without the slightest temperature.

Just as Zhang Chen was about to walk forward, a handsome young man appeared in front of him.

"Only those who have the key can enter the Old City, and everyone who enters the Old City will get a chance to get an A-rank treasure chest!"

"A-rank treasure chest!?"

Zhang Chen was a little moved, and then felt that it was not worth it, after all, it took a lot of effort to get the A-level treasure chest, which was indeed a little stingy.

"Who are you? You're not human? ”

Zhang Chen looked at the young man in front of him, and he couldn't sense anyone's breath on him.

"As you can imagine, I'm not human, but the steward of this former city, a machine spirit!"

"Oh? It is rumored that the treasure of heaven and earth has a spirit, and will choose the master, and this former city is still a treasure? ”

"Indeed, this whole city is a treasure."

The machine spirit smiled and admitted, "But it has nothing to do with you!" ”

Although the machine spirit said it was ugly, Zhang Chen didn't have a temper.

He wasn't confident enough to be able to kill the machine spirits with his own strength and snatch the entire former city.

Just standing here, he already felt a great deal of coercion.

"By passing my two tests, you can get an A-rank treasure chest, and if you succeed in two tests, you can also get an additional reward."

"An extra bonus? What are the additional rewards? ”

"We'll find out when you clear the customs."

"Now you have two choices, either turn around and go back, or pass my test."

"Of course, since there are rewards, there are naturally risks, and there is also the possibility of death."

"Do you choose to turn back, or move forward?"

Although the machine spirit looked at Zhang Chen, although he smiled, he was extremely indifferent.

"Of course I choose to move forward, there's no reason to enter Baoshan and return empty-handed, right?"

The machine spirit nodded and said, "The test is divided according to the level, and you will be assigned a ten-level test. ”

Zhang Chen secretly rejoiced in his heart, although he was only level ten, he might be much stronger than people of level fifteen or even higher.

The rank cannot measure one's combat effectiveness at all, and it does not even have any reference value at all.

"By the way, what are you good at?" The machine spirit suddenly turned around and asked.

"Me?"

"I'm good at strength and speed?"

Zhang Chen's uncertain answer, could it be that this machine spirit is planning to formulate the level with what he is good at?

In this way, it is better for yourself.

The machine spirit thought for a moment, "Well, then you have to avoid the options of strength and speed. ”

Ji Ling's words surprised Zhang Chen, but he didn't expect this guy to want to calculate himself.

Who are these TMs?

Other people's machine spirits are all kinds of good, all kinds of water, this guy is good, he doesn't want to get any benefits at all.

"Alright, you come with me."

The machine spirit seemed to have finished thinking and took Zhang Chen to a gate.

"After entering, there are two rooms in total, and the rules are written on the door, you can see for yourself."

"I'll wait for you to get through."

The machine spirit dropped such a sentence and disappeared.

Throw Zhang Chen at the door and messy in the wind......

"Grass! I'll kill it if I have a chance! ”

Zhang Chen pushed open the door and walked into the room, and there was a door inside.

There was a note on the door.

"If you step on the right path in the first level, you will be successful, and if you fail, you will be swallowed up by the wrong path, please choose carefully."

A simple sentence dominates the fate of Zhang Chen, and Zhang Chen is also very unhappy.

In short, after seeing this machine spirit, Zhang Chen was all kinds of unhappy!

After pushing the door open, Zhang Chen was angry, but he was not carried away, but calmly and carefully observed the road.

The room is a bit similar to Japanese-style tatami mats, but the tatami mats are of a different shape, and they are about 50 steps away from the next door.

On either side of the room are two stones that radiate energy.

"This stone is the reward?"

Zhang Chen frowned slightly, the risk of not taking the reward is small, if you want a reward is double the risk, but if you want to get both stones, it is several times the risk!

One wrong step can lead to a catastrophe!

Carefully observing the tatami mats, Zhang Chen did not plan to leave before it was confirmed, anyway, there was no time limit for this level.

"Tatami mats have different shapes, but some of them are the same, so is this the standard?"

"No, no......"

"It's too far away, it can't be a jump, right?"

Zhang Chen made a difficulty, this machine spirit did choose a level for him that could hardly be used in strength and speed!

I don't know what the situation will be if I take a wrong step, and Zhang Chen doesn't dare to gamble.

It would be nice if someone was there at this time, so that other people could be the scouts for the dead ghosts, and they could make plans......

After a long time, Zhang Chen didn't see any clue, in front of his eyes, the door was completely open, and he could choose a tatami mat to move forward on a line.

"A total of six tatami mats......"

"It's not the same as a maze, it's even harder than a maze."

"If you make a mistake in the labyrinth, you can turn back, but if you can't turn back here, you will die!"

"Huh!?"

Zhang Chen's brows stretched slowly, and then he walked towards one of the tatami mats very confidently.

And the tatami mat standing at Zhang Chen's feet sank slightly, and there was no change.

Immediately afterwards, Zhang Chen continued to move forward, and every step was very confident, without a pause or hesitation.

Zhang Chen became more and more confident as he walked, and he had already walked to the wall on the left side and successfully got the fiery red stone that was radiating light.

"The median fire elemental stone has a strong fire elemental power, which can replace its own energy use."

"Elemental Stones?"

Zhang Chen is also the first time to contact this thing, and it is warm and warm in his hand, which is very comfortable.

"There's one more."

Zhang Chen observed the ground for a moment, and then walked towards the other wall.

The tatami mats under his feet all turned into a colorful city, and Zhang Chen got another cyan stone.

"The median wind elemental stone has a strong wind elemental power, which can replace its own energy use."

"Another elemental stone."

"I don't know what the value is."

Zhang Chen smiled, there were not many tatami mats left, but it was enough to step into the second room by himself.

The last tatami mat changed color at Zhang Chen's feet and then sank.

"This Tetris design is really clever."

Zhang Chen smiled, in fact, countless tatami mats are like countless Tetris.

You just need to piece together Tetris at the angle you are walking to solve the problem of this room.

So when Zhang Chen finished walking, all the Tetris he walked changed color as if they were eliminated, and only those tatami mats that could not be walked were left.

Under the tatami mats, it is as dark as the abyss, and you can feel the tremor of your soul when you look at Zhang Chen more!
