"Okay, let's use fluorescent coral!" Xiao Yi replied, "Help me prepare more!"

"Okay, please wait a moment, it will be fine soon!" said Ling Niji.

Soon, a guard swam over with a pile of corals glowing white.

Looking at those fluorescent corals, Xiao Yi felt like the fluorescent sticks in the previous world, even brighter.

"Thank you!" Xiao Yi took the coral and said, "Patriarch Ling, I have an idea, you can consider it."

"Please say it!" Ling Jiji said.

"There are some specialties on the bottom of the sea that are not available on the island and in the shallow sea, so you can collect some and try to sell them in the market on our island. At the same time, there are also many grades of food on our island for sale, so that the materials can be circulated. ." Xiao Yi said.

Ling Niji's eyes lit up: "What a great idea!"

In this way, their mermaid clan will have an additional source of income-level food, and the Spirit Injury is naturally very happy.

Xiao Yi continued: "If you can handle the biochips on my island, it will be very convenient to trade. Of course, this is just a suggestion, not a requirement."

"We will handle it!" Lingsha said as she swam from the side.

After seeing Lingsha, Xiao Yi said with a smile: "Yes, she knows better, let her talk to you in detail."

"Okay, I'll ask carefully later." Ling Niji nodded.

Xiao Yi took the fluorescent coral and left the mermaid clan.

Lingjie carefully asked Lingsha for information about biochips.

After introducing it again, Lingsha said, "Father, this is an opportunity to shorten the distance with Xiao Yi Island Master! The mermaid should seize this opportunity."

Ling Niji pondered slightly: "Is that biological chip really so magical?"

"I've only seen them trade a few times, maybe there are more functions, I don't know yet." Lingsha replied.

Ling Jiji was silent for a moment, and said, "Call on the whole family to apply for implantable biochips."

Hearing her father's order, Lingsha was very happy. In her opinion, their mermaid family must seize the opportunity to follow Xiao Yi's footsteps.

She has a hunch that as long as they keep up with Xiao Yi, their ethnic group will grow and develop quickly in the future!

Xiao Yi took the pile of fluorescent corals and returned directly to his bedroom. It was already too late. Xiao Yi was going to take a night's rest and come back during the day tomorrow.

Anyway, the energy spar is not so urgent now!

"Hey, what is this?" An Ran just came to Xiao Yi's bedroom and saw that there was a stick-like substance in his hand that was glowing with strong light.

"Fluorescent coral, ready to explore the deep sea!" Xiao Yi replied.

"What? How can it be so bright?" An Ran said in surprise, "Before, there were fluorescent corals in our fish tank, and they needed to be illuminated by light to emit bright light."

"Does it need light?" Xiao Yi asked suspiciously.

An Ran nodded and replied, "Yes, at that time, I also specifically checked the principle of fluorescent coral luminescence. Fluorescence is a phenomenon of photoluminescence. In short, it converts short-wave light into long-wave light and emits it. "

"Really? But the mermaid family seems to be able to shine with only this!" Xiao Yi said suspiciously.

"Then let's try and find out!" An Ran said, "As long as we create a completely dark environment, we will know whether it can shine!"

"There!" Xiao Yi grabbed a fluorescent coral, pulled An Ran with one hand, turned off the light, and got into the bed with An Ran's exclamation.

"It's only nine o'clock..." Before An Ran could finish speaking, she saw the fluorescent coral glowing yellow, and it even felt brighter than under the light.

"How could it be like this?" An Ran's eyes widened, "This is unscientific!"

"It seems that the rules of these two worlds have similarities and differences. It doesn't matter. If we say unscientific, it is the biggest unscientific that we came to this world!" Xiao Yi shrugged helplessly.

An Ran nodded and replied, "Yes, there are not many things in this world that are scientific! By the way, where are you going to explore tomorrow?"

"A survivor opened an energy spar vein map from the treasure chest before, and it turned out to be on the bottom of the sea." Xiao Yi replied.

An Ran said, "Well, then you should rest early!"

"Hey hey, I've already come, do you still want to leave?" Xiao Yi laughed.

An Ran exclaimed, and then lost herself.

The next day, An Ran got up early, took a shower, and went to prepare breakfast.

Xiao Yi immediately chose to sign in.

"Sign in successfully, get reward: contract card (SSS level)*1."

Xiao Yi was stunned for a moment: "System, are you playing with me? Now give me this reward? How good is it to give me yesterday, then I guess I can bring the Holy Light Empire under my command!"

"I gave it to you yesterday, and you can't accept the Holy Light Empire, at most one SSS-level wizard!" The system responded miraculously.

Xiao Yi was stunned again: "What do you mean? Isn't the wizard with the highest status in the Holy Light Empire?"

The system fell silent again.

Xiao Yi is also helpless about the system, feeling that some information is not necessarily unknown to him, but he will tell himself selectively.

Xiao Yi shook his head: "Okay, it's better to have another SSS-level wizard come to your door today!"

After finishing the breakfast, Xiao Yi immediately teleported to the energy spar mine.

Tie the fluorescent coral to yourself and swim to the bottom of the water.

With fluorescent corals, when I dived to the same position again, my eyes were finally no longer as dark as yesterday.

It can be seen clearly from a distance of five meters in a radius beside them.

"Let's continue!" Xiao Yi said, and continued to dive with the two of them.

As the depth of the dive continued to increase, Xiao Yi's shock was constantly refreshed.

"Islander, this energy spar vein is too deep!" said the soldier on the side.

Xiao Yi nodded, then immediately withdrew the soldier, and a huge tentacle rolled towards him.

"Giant Octopus (S-Class):..."

It was only S-rank, Xiao Yi drew out his Xuanyuan sword and stepped forward to kill him.

The soldier said with lingering fears: "Thank you, Island Master!"

Xiao Yi waved his hand and said, "Be careful!"

"Yes!"

Next, I encountered several S-class deep-sea creatures, all of which were easily solved by Xiao Yi.

But Xiao Yi's brows furrowed. So far, there is no sign of going to the bottom of the sea.

And as the marine life becomes more and more powerful, although the level is still S-level, the strength is getting stronger and stronger.

"Is this spar vein also a copy of a treasure? Or will you encounter these high-level creatures when you enter the ocean?" Xiao Yi pondered.

If it is a dungeon, it would be better. The map opened by the current survivors will not have a high level limit of monsters.

But if it's the latter, there's a good chance that there will be SSS-level deep-sea creatures underneath, which is troublesome!
