Riding on the warship and drifting above the sea, Yang Yu opened the panel and looked at the seven keys on the system.

I thought [Blood Earl] and held one or two keys in his hand, but in the end I had three keys.

If he had known that [Blood Earl] had so many keys, Yang Yu would have taken out two more keys to exchange legendary equipment when he was negotiating with [Dragon God's Power].

I don’t know if they can use the keys to exchange for legendary equipment.

Judging from Yang Yu, it is probably because there is no chance.

[The Power of Dragon God] is tracing the resurrection of the Goblin Emperor. In order to use the key in his hand as a condition for exchange, Yang Yu directly stated [The Power of Dragon God] that if the Goblin Emperor could not be found anywhere, the Goblin Emperor was most likely to hide in the maze built by the brave Lax.

Although there is no news about the [Majesty of the Dragon God], with their strength, most of them have already collected the required keys and no extra keys are needed.

Maybe I have already seen what the underground maze that I summoned with five keys is like.

The sea breeze blew across Yang Yu's cheeks, and Oias's voice came from the mast:

"You can already see the harbor."

Luo Luosi, not far from Yang Yu, breathed a sigh of relief and took off the straw he was holding: "It's finally here. Even if the ship suddenly overturned at this distance, there is no need to worry."

After several days of running around, Yang Yu and the others finally arrived at the first port where they could replenish supplies.

Such ports are rare and uncommon in maritime principalities.

The Principality of the Ocean is the home of most seaweed species. Most seaweed species live under the sea, and only a very small number will live near the coast. However, this does not mean that they will completely sever their ties with the outside world. On the contrary, they are very interested in various novel objects outside.

The maritime principality also has many unique products, which gives the premise for trade between the two sides.

In order to ensure the smooth progress of trade, the Principality of the Ocean has opened up trade ports.

Such trade ports are usually set up on the high seas without any sea species. When they arrive here, there are ways to go to various countries on land.

After thinking for a while, Yang Yu took out all five keys and held them in his hand.

Now Yang Yu doesn't know where the underground maze that these five keys can be opened is. If the underground maze is in the ocean principality under their noses, he will also facilitate the plan before the world's demon king arrives.

Five keys of different colors kept emitting light in Yang Yu's hands, jumped out of Yang Yu's hands, and flew into the air. They surrounded each other into a ring and began to rotate continuously, creating a unique resonance.

Lolosi and Bai Jin both looked at the five keys flying in the air, and a magic circle appeared in the center of the key.

"It's the storage magic circle." Bai Jin was a little surprised.

When she was free, Yang Yu also showed her the key, but there was no trace of magic on the key, and it looked like an ordinary key no matter how you looked.

But now, not only does the key emit strong magic power, but also a storage magic array is drawn in the air.

Bai Jin didn't know how these keys were made, and this involved some of her blind spots in knowledge. Sure enough, magic is a profound science, and there is still a lot to learn in the future.

The white storage array emitted a soft light, and a square box slowly fell from the center of the array and fell into Yang Yu's hand.

The box was brown-red and just the size of Yang Yu's palm. It was painted with a large blue tree with branches and leaves.

Before Yang Yu could look at the box carefully and see what was in the box, the box opened and showed five slots.

The keys floating in the sky are one after another, and are accurately stuffed into the slot.

The key stuffed into the slot showed an extremely special and strange pattern, which were double helixes intertwined with each other.

After all the keys are installed, the box is closed on its own initiative.

The blue tree on the cover gradually began to converge its light and turned into a dot, and then quickly expanded into magic circles, engraved on the box.

A new task appeared on Yang Yu's system:

[Hidden strategy mission: [History of history]

Mission description: When you guide the underground maze of Rawx, by chance, you get strange keys from your past companions, friends, and enemies.

After collecting five, a unique and interesting chain reaction occurred between the keys, opening up the special underground maze left by the brave Lax [the palace of history].

Mission requirements: Guide the palace of history and insert the key to the place where he should insert it.

Task reward: experience??????, number of lottery draws????, gold coins???, free attribute points????, skill points???.

After completing this task, you can settle the hidden task [Raux, the Ancient Brave] at any time.

Hide conditions: faster than anyone else, reach the last level.

Reward: A choice.]

Quite ambiguous task description.

I don’t know when it started, but Yang Yu received more and more tasks of uncertain rewards.

But Yang Yu didn't think this was a bad thing.

Perhaps it is because I am standing step by step that task rewards are becoming increasingly difficult to evaluate.

But... it's faster than anyone else to reach the last level, and reaching a reward is just a choice. What exactly is this choice?

If you want to know, you can only go there yourself. Anyway, Yang Yu is worried about how to get through the Demon King before he arrives.

Whether from Lotna's mouth or from other succubus, Yang Yu did not get much information about the Demon King Army. He had no way to prepare, so he could only find a way to gain more experience in various places.

The palace left by the brave Laux happens to be a good place to go.

After thinking about it, Yang Yu suddenly realized something very important.

Damn, you asked me to guide the underground maze, but you didn't even tell me the location of your [History of History]. Do you want me to look for it all over the world?

Yang Yu started to tinker with the box and wanted to open it, but found that no matter how hard he tried, he could not open the box.

Even if Yang Yu took the [Wheel of Reversal] from Lotkar, instantly increased his strength to 9999, and drove a few skills to increase strength and used his energy to make a living, he still couldn't open the box. It was like getting on a super black car and being completely welded to death outside.

Yang Yu shook his head helplessly, and at this moment, Bai Jin slowly leaned over, his eyes fixed on the cover of the square box, and said:
Chapter completed!
