"OK, then use fluorescent coral!" Xiao Yi replied, "help me prepare more!"

"OK, please wait a moment. It will be ready soon!" said linginverse halberd.

Soon, a guard came swimming with a pile of coral with glittering white light.

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

"Thank you very much!" Xiao Yi took the corals and said, "leader Ling, I have an idea that you can consider."

"Please say!" said linginverse halberd.

"There are some specialties at the bottom of the sea that are not found on the island or 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 many grade foods on our island, so that the materials can be circulated," Xiao Yi said.

Linginverse halberd's eyes lit up: "good idea!"

In this way, the mermaid family has a source of income level food. Linginverse halberd 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 only a suggestion, not a requirement."

"We'll handle it!" Lingsha swam over and said.

After seeing Lingsha, Xiao Yi smiled and said, "yes, she knows better. Let her talk to you carefully."

"OK, I'll ask carefully later." linginverse halberd nodded.

Xiao Yi left the mermaid family with fluorescent coral.

Linginverse halberd carefully asked Lingsha about the biochip.

After Lingsha introduced it again, she said, "father, this is an opportunity to narrow the distance with the leader of Xiaoyi island! The mermaid family should seize this opportunity."

Linginverse halberd thought slightly: "is that biochip really so magical?"

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

Linginverse halberd was silent for a moment and said, "call on the whole family to handle implanted biochips."

Lingsha was very happy to hear her father give such an order. In her opinion, their Mermaid family must seize the opportunity to keep up with Xiao Yi.

She has a hunch that as long as she keeps up with Xiao Yi, their ethnic group will soon develop and grow!

Xiao Yi took the pile of fluorescent corals and directly returned to his bedroom. It was too late at this time. Xiao Yi was ready to rest for one night and go again during the day tomorrow.

Anyway, the energy spar is not so urgent now!

"Eh, what's this?" Enron happened to come to Xiao Yi's bedroom and saw that there was a bright rod-shaped material in his hand.

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

"What? How can it be so bright?" Enron said in surprise. "Before, there were fluorescent corals in our aquarium, which needed light to shine."

"Do you need light?" Xiao Yi asked suspiciously.

Enron nodded and replied, "yes, at that time, I specially checked the principle of fluorescent coral luminescence. Fluorescence is a photoluminescence phenomenon. In short, it is to convert short wave light into long wave light."

"Really? But it seems that the mermaid family can shine only with this!" Xiao Yi said suspiciously.

"Let's try!" Enron said. "As long as we create a completely dark environment, we will know whether we can shine!"

"Yes!" Xiao Yi grabbed a fluorescent coral, pulled Enron in one hand, turned off the light, and got into the quilt in Enron's scream.

"It's only nine o'clock,..." before Enron finished, he saw the fluorescent coral emitting yellow light, and even felt brighter than under the light.

"How could it be like this?" Enron stared. "It's unscientific!"

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

Enron nodded and replied, "yes, not many things in the world are scientific! By the way, where are you going to explore tomorrow?"

"Before, a survivor drew a map of energy spar vein from the treasure chest, but it turned out to be at the bottom of the sea." Xiao Yi replied.

Enron said, "well, let's have a rest early!"

"Hey, hey, you're all here. Do you still want to go?" Xiao Yi said with a smile.

Enron exclaimed, and then he lost himself.

Only level s, Xiao Yi drew out Xuanyuan sword and came forward to kill it.

The soldier said with lingering fear, "thank you, island Master!"

Xiao Yi waved his hand and said, "watch out!"

"Yes!"

Then he encountered several batches of S-class deep-sea creatures, which were easily solved by Xiao Yi.

But Xiao Yi frowned. So far, there is no sign of reaching the bottom of the sea.

With the deepening, marine life is becoming more and more powerful. Although the level is still level s, its strength is becoming stronger and stronger.

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

If it's a copy, it's OK. The upper limit of monster level in the map issued by the current survivor will not be too high.

But if it is the latter, there may be SSS level deep-sea creatures below, which is troublesome!
