Because it is already summer, the city of Treasure Curtain Fairy City is already a little hot and dry during the day, and at night, there is a gust of sea breeze on the beach, which is a little cool.

Taking the boat, Ye Ming went to do three aquatic tasks first. Anyway, he had to go to sea, and Ye Ming took on three aquatic tasks by the way.

For Ye Ming, the second-level aquatic task is naturally easy to complete.

In the shallow water area, Ye Ming took out the reward compass obtained by defeating the wild boss. The scale on this compass has basically been worn out, the style is very old, and some of the handwriting on the compass has been blurred, but it doesn't matter, there is a tattered long needle on the compass, and the direction that the long needle points to is where Ye Ming is going.

After drifting in the hedge sea for nearly half an hour, after entering the deep sea area, the long needle on the compass stopped moving within a certain area.

Ye Ming looked around, all of them were endless seas, and there was not even a place to stay.

"This compass doesn't mean it's at the bottom of the sea, is it?" Ye Ming thought about it, it seemed that there was only this one possibility, and it was impossible to be in the sky.

Taking off his shirt, Ye Ming jumped directly into the sea wearing a vest. He began to dive, and the underwater world was pitch black, and he couldn't see anything.

The fluorescent lantern could not be used in the sea, so Ye Ming dived about 30 meters into the sea and swam up again.

Diving, every professional can do, how long you can dive, how deep you can dive, this is only related to one factor.

That's mana.

Dive consumes 10 mana per second, and every minute that passes, the mana consumed per second doubles, for example, the second minute costs 20 points per second, the third minute is twice as much as 20, which is 40 points, and so on.

The depth of the dive will also consume mana, with a phase of 50 meters, less than 50 meters, the mana cost per second will be 10 points, and above 50 meters, it will be doubled to 20 points, and so on.

This is a double mana cost, one is the mana cost of the dive duration, and the other is the mana cost of the dive depth.

It's not that Ye Ming doesn't have enough mana, just for a while, the consumption rate of mana is not as fast as his recovery rate per second.

He just felt that the depth of the sea here should be more than 50 meters, and the deep sea was pitch black, and if he wanted to find the advanced core stone, he still needed light.

Ye Ming returned to the wooden sailboat, entered the Heavenly Trench Valley, and went straight to the residence of the master craftsman.

"Master, haven't you rested so late?" Ye Ming rushed to the casting room of the master of the divine craftsman, who was creating a certain item.

"You kid hasn't been diligent enough lately, and it's been a while since you've come to me to practice building. I said that it rained heavily in Tianchi Minghai some time ago, and you didn't see anyone all day, and the rain was so heavy, why did you go? Now that the rain has stopped, you kid still hasn't come, you've learned to be lazy, haven't you? Master Divine Craftsman glared at Ye Ming.

"I ......" Ye Ming was speechless for a while. Some time ago, the heavy rain in Tianchi Minghai did not stop, and the number of mobs refreshed by the hunters was very small, so Ye Ming had to spend more time waiting for the mobs to refresh, and it was true that he hadn't come to Master Shenjiang for a while.

"Okay, the master just asks about your private affairs, what are you looking for me for?" Master Divine Craftsman waved his hand.

"Master, is there a sinking fish lamp here in Tianqian Valley?" Ye Ming asked.

"Sinking fish lamp? Is it the sinking fish lantern floating around the underwater world of Crescent Bay? Master Divine Craftsman asked.

"Yes." Ye Ming nodded.

"We don't have it here, it's only for water, but I can get someone to do it for you. The sinking fish lamp does not belong to the things that are created, and there are some craftsmen in the Tianqian Valley who will make the sinking fish lamp. What do you want this for? Master Divine Craftsman said.

"There is an emergency." Ye Ming said.

"I'll give you an address, and you'll go to the craftsman yourself. He should know you, the sinking fish lamp is not a valuable item, it doesn't cost a few dollars, you have gold coins in your pocket, right? Master Divine Craftsman asked.

"Yes."

"Okay, just this address, you go to him, and I estimate that I will get it out for you in half an hour."

"Thank you, master."

Ye Ming found the craftsman according to the address written by the master craftsman and explained his intentions. Because there was no inventory, the craftsman immediately began to make fish lamps for Ye Ming.

There are 15 in total, and it takes an hour to finish.

After paying, Ye Ming returned to the fence sea area with 15 sunken fish lanterns. The depth at which these 15 sinking fish lamps can sink to the bottom of the sea is between 30 and 70 meters, which Ye Ming requires to be made at such a depth.

The sunken fish lantern is a feature of Crescent Bay, which can sink into the sea and provide a wide range of light.

Jumping into the sea, Ye Ming scattered the sinking fish lamp into the deep sea. Each of the 15 fish lanterns floats at a different depth, ranging from 30 meters to 70 meters.

Suddenly, the bottom of the sea became transparent.

The depth of the sea here is 55 meters, as Ye Ming estimated. Part of the seabed has been lit up by sunken fish lanterns, and you can see sand, stones, vegetation and some fish swimming around.

"Shipwrecks?" Through the light of the sunken fish lamp, Ye Ming saw a huge wooden shipwreck at the bottom of the sea.

The wreck has been washed and eroded by the sea, the wreck is covered with all kinds of seaweed, the mast is broken to the side, and there is a huge hole on the right side of the shipwreck's hull.

Ye Ming dived near the wreck, searched carefully, and found a small wooden box in the sand at the bottom of the wreck.

When the wooden box was opened, there was an E-class field core stone.

After getting the core stone, Ye Ming searched near the shipwreck again, but found nothing, so he swam up.

"It's as simple as that?" Ye Ming looked at the core stone in his hand, it was an E-level core stone, yes.

No matter how much, Ye Ming drove the boat back to the Treasure Curtain Fairyland.

It was already eleven o'clock in the evening. Ye Ming walked to the building where the core stone of the city was located and entered the basement.

This is the location where the core stone is stored, this basement is the prototype of Uncle He's simulation, designed by Lu Xunchuan, Xue Dongying placed various defense mechanisms, and the architects carefully built it.

The safety factor is very high.

Walked to the room where the core stone was, passed the system certification, and Ye Ming entered the room. Placing the E-grade core stone he got next to the city core stone, Ye Ming chose to use the core stone to advance.

"The Core Stone is not activated." The system sound is heard.

Not activated?

After using this core stone, Ye Ming saw that the core stone came with a message: "Please defeat any boss who ranks 1000 in the Ancient List, and get the ranking to activate it." ”

"Kuanggu Bang?" Ye Ming was stunned when he saw these three words.

What does that mean? The ancient era, the ancient and post-ancient Ji Ye Ming all knew, but this ancient list, he saw it for the first time.

"Ask Uncle He." Ye Ming walked out of the basement and found Uncle He in the conference room, who was with Lu Xunchuan.

When the two heard Ye Ming's Kuanggu list, they both said that they had never heard of it.

"Why don't you ask Baili Jianyang, this mysterious guy?" Ye Ming thought about it and felt that he could ask Baili Jianyang.

After the copy of Zongle Changsheng came out, Baili Jianyang had been playing this copy, Ye Ming squatted at the door of the copy and waited, and about five minutes later, Baili Jianyang came out.

"Hey, I'll play the copy later, I'll ask you something." Ye Ming shouted, and immediately wanted to continue to enter the copy of the Baili Jianyang.

"You won't ask me about the end of the beach again, will you?" Baili Jianyang turned around and asked.

"It's not. Do you know the Ancient List? Ye Ming asked.

"Huh? Do you actually know the Kuanggu List? Baili Jianyang glanced at Ye Ming curiously.

Judging by this guy's reaction, he does know.

"I don't know, so I'll ask you." Ye Ming said bluntly.

"I thought you knew. In this world, there are no more than 500 people who know the Kuanggu list. If you don't know the ancient list, then you must not know the world copy. ”

"In the present era, a lot of cities have developed, and each city has its own copy, and the professionals to whom the city belongs are playing a copy of their own city."

"And in this world, there is a copy of the world. As the name suggests, a world quest, i.e. people from every city can enter this quest. However, low-level cities do not have this qualification. Baili Jianyang said.

A copy of the world? Ye Ming really heard of it for the first time.
