[Ding! Congratulations on building the underwater water cannon tower. You have received 30 experience points and 3,000 gold coins.]
"Finally!" Lei Xiu said, his eyes shining brightly.
Lei Xiu walked excitedly to the side of one of the underwater turrets. He realized that the first shell of the underwater turret needed to be controlled by someone, and there was no need for it after that.
Hence, Lei Xiu impatiently pressed the switch, wanting to see the power of the underwater turret.
As he turned it on, a strong suction force came from the bottom of the underwater turret. The pure energy in the surroundings was attracted to the bottom of the underwater turret, and a head-sized cannonball gradually formed at the muzzle.
Although the cannonballs condensed from the underwater cannon turrets were not as big as those condensed from the water cannon turrets on Mermaid Island, the energy contained within them was entirely different. The energy from the cannonballs of the underwater cannon turrets was almost double that of the ones from Mermaid Island!
"This… this energy… is so pure!" Lei Xiu felt his heart palpitate as he looked at the cannonball condensing in the underwater turret.
As time passed, in just a few breaths of time, the cannonball condensed at the muzzle gradually solidified.
Boom!
With a loud boom, the cannonball in the muzzle shot out towards a rock in front.
The sound of collision resounded, and the cannonball exploded, forming an even greater force. The bottom of the sea shook, and circles of ripples swept over. Every creature was thrown back by this force, while some small fish in the surroundings were directly blasted unconscious or directly killed.
On the other hand, the black rock didn't move at all, but if one took a closer look, one would notice that there was a thin crack where the cannonball had struck!
"There's actually a crack!" Seeing this result, Lei Xiu was extremely shocked!
Although the Razor Tiger Sharks could not see the surface of the black rock not far away, they could guess the power of the underwater water cannon from the commotion. They were also shocked. They did not expect their Island Master to have such a weapon. It was much stronger than the weapon he had used to deal with them!
Lei Xiu did not randomly attack. He specifically chose a target, a rock not far away that was emitting black light. This rock was called Black Essence Rock. It was only produced in the deep sea and was known for its toughness! Ordinary weapons would not be able to cause any cracks on it!
But now, the Black Essence Rock had been cracked by the underwater turret's cannonball!
"Not bad, not bad!" This made Lei Xiu so happy. He kept laughing.
"Congratulations, Island Master! With this weapon, we don't have to worry about the safety of the Seed of the Ocean Tree anymore!" The Razor Tiger Shark and the others, who were not far away, saw that their Island Master was so happy and knew that this weapon had definitely made Lei Xiu satisfied. They could not help but smile obsequiously.
[Ding! Congratulations to the host for completing the main mission. You have successfully upgraded the Seed of the Ocean Tree from the sprouting stage to the seedling stage. You have gained 30 experience points and 3,000 gold coins.]
At this moment, a booming sound echoed and attracted the attention of Lei Xiu who was still in conversation with a Razor Tiger Shark.
In the central area, the seedling of the Ocean Tree, which was a few centimeters tall, suddenly seemed to have broken through its shackles and grew rapidly!
Its entire body emitted a faint green light. As the Ocean Tree seedling grew larger, the green light on its body became more and more resplendent, and a faint fragrance was emitted. After a few breaths of time, the Ocean Tree stopped growing.
At that moment, the Ocean Tree had grown to a height of more than ten meters! Its diameter was several meters! It was comparable to a tree on land, but this was only the seedling stage of the Ocean Tree!
"It's… it's too tall! I didn't expect it to be so tall, just as a seedling! As expected of the Ocean Tree that can grow to hundreds or thousands of meters tall! It's so amazing!" Looking at such a tall Ocean Tree, Lei Xiu couldn't help but sigh.
Sharkwood and the other sharks were dumbfounded. How could they have seen a legendary thing like the Ocean Tree? Now that they'd personally witnessed its growth, they were naturally extremely shocked.
It was also at this time that the pressure field around the central region vanished with the advancement of the Seed of the Ocean Tree from one stage to another!
"Island Master! This… this fragrance is so attractive to me!" As soon as the pressure field vanished, Sharkwood and the others arrived beside Lei Xiu. Sharkwood's eyes were red as he struggled to speak.
Seeing Sharkwood in such a state, Lei Xiu deeply understood how enticing the fragrance emitted by the Ocean Tree was to other creatures.
"Wake up!" Lei Xiu slapped Sharkwood's body with both hands, sending a burst of energy toward him.
"Island Master!" Sharkwood's eyes instantly cleared up, and his entire body shivered as he spoke with panic.
"Yes! I have some medicine here. If you eat it, the fragrance will no longer be attractive to you." As he spoke, Lei Xiu bought the medicine from the system and handed it to Sharkwood and the others.
"How magical!" Sharkwood and the other sharks naturally believed the words of their Island Master. They all took the medicine, and instantly, the fragrance that had attracted them previously became no different from an ordinary fragrance.
"If this fragrance is so attractive to all of you, then so will it attract the other creatures in this area. Perhaps they're on their way here now. Although we have the underwater cannon turret, we have not seen the specifics after all, so we have to make preparations in advance!" Lei Xiu said after pondering for a while.
"Yes! Island Master!" Shark Tree and the others spoke with solemn expressions. They knew the importance of the Ocean Tree, so they naturally did not dare to be careless.
…
What Lei Xiu said was right. At this moment, there was a group of sea serpents rapidly rushing over from thousands of meters away from Lei Xiu!
They were one of the four overlord-ranked species of this sea region! The Sea Serpent Clan!
The longest of them could reach dozens of meters. They were incomparably huge, and their strength was astonishing. They had the most vengeful nature, and most importantly, they could spit out a type of poison! The effects of this poison were extremely shocking! Even creatures from the four great clans would not dare to provoke them.
"Black Serpent! Is what you said true? There's a treasure there?" A sea serpent at the very front spoke slowly. The tip of its head had a smear of red on it. The rest of the sea serpents all had a smear of green instead. It seemed that this serpent had quite a status within the clan.
"It's absolutely true, Big Brother! How could I dare lie to you! When I was searching over there, I suddenly noticed a faint fragrance. Even though the fragrance was very faint, it was very attractive to me!"
"At that time, my head was dizzy. When I suddenly woke up, I realized that I had travelled several hundred meters forward without any consciousness! So I rushed over to tell Big Brother that there must be treasure here!" The serpent called Black Serpent said with a flattering smile.
"Hmm… If it's true, we'll reward you handsomely!" the sea serpent leader said.
"Thank you, Big Brother!" Black Serpent said excitedly.
