Crazy loot box opening! Crazy fishing! Crazy survival!

"Boom~"

Nine red-flame fire dragons slammed into the deformed giant monster, erupting with scorching heat.

The air became dry and distorted, the pools on the islands dried up one after another, and even the sea water evaporated on a large scale, with huge amounts of water vapor surging into the sky.

As for the deformed monster, it gradually dissipated in the scorching red flames, leaving no trace of even ash.

"Ding~"

"Ding~"

"Ding~"

Several system prompts sounded in succession, and Mu Yu had no time to check. He just felt that his back was about to be roasted.

Looking back at the fireball that was still releasing heat, Mu Yu gritted his teeth and threw in ten red crystals with depleted fire elements.

"Pah~pah~pah~"

A crackling sound erupted from the blazing fireball, and the heat quickly faded away and soon dissipated. Only ten red crystals rich in fire element fell to the ground in the air.

"Ding~ Trial successful, island advancement!"

"Congratulations to Mu Yu from 445 Central District for being the first to be promoted to a Tier island and receiving extra rewards. The Central District Island Rankings are now open."

"Additional Reward: Wonder Level +1 Nine Dragons Earth Fire (Rare) - Nine Dragons True Fire (Excellent)"

Additional Reward: Wonder Level +1 Iron Vein (Rare) - Iron Secret Vein (Excellent)

"Ding~ The island terrain editing blueprint has been activated. Please complete the editing within one minute."

After receiving the reminder, Mu Yu had no time to be happy and quickly closed his eyes.

In his mind, a model of the entire island appeared.

Mu Yu gradually raised the island to its maximum height of nine zhang. The earth pillar in the middle was like a pillar supporting the sky, holding the entire island up in the air. From a distance, it looked like a floating island, magnificent and imposing.

AI illustration, not perfect.

After the last elevation of the island's coast, the main body of the island has a thickness of more than two meters after it protruded out of the sea.

Mu Yu also edited a stone staircase leading directly to the sea to build a dock for ships to enter and exit the island.

In the future, as long as we guard this channel, we can resist most invasions of marine life.

Mu Yu then fine-tuned the terrain of the island, dividing it into several areas with unique styles, such as the building area, mining area, farmland area, leisure area, river area, plain area, savage living area, etc.

After doing all this, Mu Yu opened his eyes and found that Xiao Gu had returned with the first snow.

The moment Mu Yu opened his eyes, thick white fog surrounded the island. The entire island rose up in the vibration and soon reached a height of nine feet. The area of ​​the island was also constantly expanding, ushering in the freedom of land area.

When the white mist dissipated, the whole island looked brand new. Little Gu flew into the air and looked at the island in amazement, and Chuxue ran around on the newly added land.

The underground fire in the center of the island has turned into nine lifelike fire dragons. Mu Yu feels that he can control the temperature they release, and his control over the entire island has become even stronger.

Only then did Mu Yu feel that all his efforts were worth it, and the island now had two wonders. With a thought, he opened the island panel.

Subsidiary islands: 0/3

Belongs to: Mu Yu

Advanced Requirements: All subordinate islands are fully populated; advanced trials have been completed; 200000 soil, 200000 stones, and 200000 mud are required.

Rare Wonder x1, Rare Building x10, Excellent Building x3, (Superior Elemental Stones can be added freely)

The fourth-level island is overwhelmingly stronger than the third-level island. The earth fire furnace and fire therapy hot spring are automatically upgraded to rare-level buildings, and there are two more rare-level specialty buildings.

Looking at the requirements for upgrading to a fifth-level island, it is simply harder than climbing to the sky. Mu Yu guessed that a fifth-level island would be a watershed for most people.

At the same time, Mu Yucha noticed the miraculous changes.

[Nine Dragons True Fire (Excellent Wonder): A high-grade true fire of excellent quality, containing terrifying fire-type extraordinary elements. The island owner can control the temperature of the true fire.

The fire needs to be vented once a week, or it can be vented actively, which can be used for defense.

Damage: 7000-63000

[Iron Secret Vein (Excellent Wonder): A high-grade vein of superior quality, containing terrifying gold-type extraordinary elements. A small secret iron mine can be refreshed daily.]

The power of the Nine Dragons True Fire was within Mu Yu's expectations, but the Iron Secret Vein was no less powerful.

A small secret iron mine is refreshed every day, and its value represents 100,000 units of iron blocks per day.

If Mu Yu is patient and only takes ten pieces of mithril each day, he can get an extra amount of mithril ore every week after a few weeks or months.

However, Mu Yu thought he didn't have the patience.

After all, the current situation is that we have to seize the day and we don’t know what will happen in the future.

After learning about the wonders, Mu Yu turned his attention to the new function of the island, the subsidiary island.

[Subsidiary Island 0/3: With the consent of the island owner, an island of the same level or below can become your subsidiary island.

Once an island becomes an affiliated island, it is irreversible unless you actively remove it.

For affiliated islands, you have higher island authority than the affiliated island owner, and the level of an affiliated island cannot exceed that of the main island.

The function of affiliated islands is indeed a good thing for some island owners who have no desire to fight and have people to rely on.

But for some ambitious island owners, this is also a means to strengthen their power and control others.

"Ding~ Fire Spirit Stone +10"

After reading the island information, Mu Yu quickly stood up and picked up the Fire Spirit Stone on the ground. He noticed that there was a piece of black flesh the size of a fingernail on the ground, which was wriggling.

"Isn't this even dead?"

Mu Yu was extremely surprised. He gently pinched the small piece of black meat, and the black meat immediately struggled in his hand.

[Low-level pollution source (pseudo-legend): A small amount of flesh and blood of an evil god, of high quality and with strong pollution, capable of causing genetic mutations in organisms. The degree of pollution is uncontrollable; even higher-level organisms that consume this flesh cannot escape the result of being contaminated.]

After looking at the introduction, Mu Yu quickly threw the black meat on the ground.

Only then did he remember that when he eliminated the large deformed beast in the Nine Dragons Earth Fire, he also gained a system upgrade, but he didn't have time to look at it at that time. Now he started to look for it.

"Ding~ You have killed the low-level pollution source. Mission completed. Reward: 1 gold box, sequence hidden points +100."

"Ding~ Congratulations on your Sequence Rank reaching 1997!"
