The floating island is now at level 5.

As for the Mist Converter and Mental Shock Turret, which are the basic structures of the Floating Island, Wang Xiaoyi followed his previous approach: first maximize their quantity, then maximize their level.

The number of Misty Mist Converters and Mental Shock Turrets has reached 50, and they have all been upgraded to Lv5.

Once the Misty Mist Converter reaches Lv5, its conversion efficiency reaches 500%. The energy obtained solely from the Misty Mist Converter can completely cover the daily energy expenses of the Floating Island.

Once the Psychic Shock Turret reaches Lv5, it can deal 500,000 to 1,000,000 points of Psychic damage, and its cooldown time is reduced from 10 seconds to 5 seconds. Of course, with the increased damage, the Psychic Shock Turret also consumes significantly more energy.

Wang Xiaoyi spent another 1 trillion to upgrade the energy shield to Lv5, making it immune to any attack below the fifth rank of Gold.

However, when it came to the treasure detector, Wang Xiaoyi encountered a problem.

After upgrading these basic buildings, Wang Xiaoyi spent 2 trillion game coins and still had 3 trillion game coins left.

However, upgrading the Treasure Detector from Lv2 to Lv3 would require a full one trillion game coins, which Wang Xiaoyi was reluctant to do.

"Forget it, it takes one trillion game coins to upgrade from level 2 to level 3, and it takes another one trillion game coins to upgrade from level 2 to level 5. I definitely don't have enough game coins on me!"

After thinking for a while, Wang Xiaoyi decided not to upgrade the treasure detector for the time being, since the treasure detector was only an auxiliary tool with limited benefits to himself.

Wang Xiaoyi opened the floating building tab. After the floating island was upgraded to level 5, a new type of building was unlocked.

During this period, Wang Xiaoyi was either getting beaten up or on his way to getting beaten up, which gave him time to check what buildings he had unlocked.

Building: [Energy-Focusing Cannon]

Price: [1 trillion game coins]

Quantity: [0/1]

Description: [A unique structure on the floating island, capable of dealing massive damage after charging. The Lv1 Energy Cannon, after 1 minute of charging, can deal 10 million points of Spirit damage to the target. Cooldown: 1 hour.]

Note 1: [As a unique building, upgrading the Floating Island will not increase the building limit of the Energy Cannon.]

Note 2: [After upgrading the Energy Cannon to Lv2, it increases the damage dealt to the Spirit attribute by 5 million points, and adds a tracking function that guarantees a hit on the target. The cooldown time is reduced from 1 hour to 50 minutes.]

Wang Xiaoyi: ⊙▽⊙

After reading the description of the Energy-Gathering Cannon, Wang Xiaoyi was somewhat stunned.

"This...this damage is terrifying! 10 million points of mental damage, who wouldn't be stunned by that!"

Who could resist a weapon of mass destruction like a cannon? At this moment, Wang Xiaoyi had long forgotten about the treasure detector.

"Sorry for the game coins, I really need this cool thing!" Without saying a word, Wang Xiaoyi spent 1 trillion game coins to buy the Energy Cannon.

[Ding! You have obtained 1 Energy Cannon!]

Please select the location where the energy-concentrating cannon will be installed!

Wang Xiaoyi once again entered God's-eye view and installed the energy-gathering cannon near the city lord's mansion.

"After upgrading the Energy Cannon to level 2, it can also add a tracking function! But it requires 2 trillion game coins!" Wang Xiaoyi thought about it for a while with some difficulty.

"Sorry, game coins, I really can't resist something cool with tracking capabilities!"

Wang Xiaoyi poured all of the remaining 2 trillion game coins into the Energy Cannon.

[Ding! The Energy Cannon has been upgraded to Lv2!]

Wang Xiaoyi: Hmm~ o(*￣▽￣*)o

Game coins come and go quickly!

Less than an hour later, Wang Xiaoyi had spent all the game coins he had just earned!

However, Wang Xiaoyi also gained a lot. He opened the information interface of the floating island and checked the current information of the floating island.

Wang Xiaoyi: ╰(￣▽￣)╭

Wang Xiaoyi stood suspended in mid-air, looking down and admiring the current appearance of the floating island.

Fifty eerie mist converters are working every moment, and every minute, 50 purple-quality eerie orbs are automatically sent to the main energy chamber of the floating island.

At this moment, in the central energy chamber of the floating island, there were at least 100,000 purple mystical beads, which had been piled up into a small mountain.

Fifty mental attack turrets are evenly distributed throughout the floating island, ready to unleash a fierce attack with a mere thought from Wang Xiaoyi.

The energy shield does not normally appear; it only activates automatically when the floating island is attacked.

The treasure detector and the energy-gathering cannon are both right next to the city lord's mansion!

The treasure detector, about the size of a desk, is currently switched off.

Compared to the treasure detector, the energy-gathering cannon is undoubtedly a behemoth, larger than Wang Xiaoyi's three-story villa.

The shaped charge cannon has a circular base with a radius of over 300 meters, a thick barrel that is 20 meters long, and a barrel radius of 10 meters.

Even before the energy-concentrating cannon is fired, it can still exert a strong deterrent effect on the enemy!

However, for players on the floating island, this energy cannon brings a gradual sense of security.

There is a famous saying that axioms only exist within the range of cannons.

"My goodness, this cannon is huge!"

"Wow, this cannon! It's so cool, so awesome, it's indescribable! No wonder he's the boss, he actually managed to get his hands on such a powerful weapon!"

"With this cannon, we can walk sideways and see who dares to mess with us!" The sycophant #2 looked proud and spared no effort in praising Wang Xiaoyi's great achievements.

...

Players on the floating island felt a great sense of security after seeing the energy cannon.

Just as Wang Xiaoyi was admiring the fruits of his labor, a sudden change occurred!

A long spear, whistling through the air, hurtled towards Wang Xiaoyi's face!
