　　 Okay, a lot of zeros.

　　 However, after studying the panel of the Ocean Tree, Renn has found a way to cultivate it.

　　 "The main task is to upgrade the tree of the ocean to the bud state, the task reward: 30 experience, 3000 gold coins."

　　 The sound of the system rang.

　　It only needs 2000 gold coins to upgrade the ocean tree from the germination state of the seed to the budding state.

　　 Ryan did not hesitate, and directly chose to promote.

　　 After the 2000 gold coins were spent, I immediately saw that where the ocean tree was planted, among the soft fine sand on the bottom of the sea, a bud broke out of the sand and stood against the wind!

　　 "It's coming out~"

　　 On board the Cetus, the mermaids made joyful voices one after another.

　　 "The upgrade is successful, the main task is completed, the host gains 30 experience and 3000 gold coins."

　　 The mission was successfully completed.

　　 "The main task is to upgrade the tree of the ocean to the seedling state, the task reward: 40 experience, 4000 gold coins."

　　 The sound of the system sounded again.

　　 Lane started to improve again.

　　The gold coins required to upgrade to the seedling state have doubled, from 2000 to 4000, which is comparable to the reward of the task.

　　 But Renn still has nearly 300,000 gold coins, and he has a lot of money, and he doesn't care about that much anymore.

　　 Renn threw the gold coins in again.

　　 "Improve success, growth time is 1 hour."

　　 Suddenly, Ren saw that the shoots of the ocean tree began to grow rapidly.

Chapter 0026 Seedlings dozens of meters high! Defensive building!

　　 Rain did not use gold coins to accelerate.

　　 Gold coin acceleration, 2 times acceleration is actually the most cost-effective.

　　 2 times the gold coins, directly reducing the time by half.

　　 3 times the gold coins can only reduce the time by two-thirds, the more you go up, the less cost-effective.

　　Of course, in a particularly urgent situation, 10 times the gold coins are directly completed, and sometimes it is necessary.

　　 But this time Ren didn't accelerate and waited patiently.

　　 He didn't wait either.

　　 Because Ren saw that there was a column of defensive buildings on the panel of the Tree of the Sea.

　　The panel of Mermaid Island also has a column of defensive buildings, but the defensive buildings of the Tree of the Sea are different from the defensive buildings of Mermaid Island.

　　 There is no water arrow tower in the defensive building of the Tree of the Sea.

　　 is an arrow tower under the sea.

　　 Of course, there are other defensive structures.

　　 For example, a defensive structure that can float in the water, and a defensive structure that can be built on the ocean tree, but it has not been unlocked yet.

　　 will not be unlocked until the tree of the ocean continues to grow.

　　 The price of a submarine arrow tower is not cheap. It is four times more expensive than a water arrow tower and requires 2000 gold coins.

　　 However, being able to spend two thousand gold coins to own a submarine arrow tower on the bottom of the sea is such a good thing that no one else would even think about it.

　　 After Ryan asked the five mermaids to guard the growing tender teeth, they began to find a suitable position.

　　 "The tree of the ocean is two thousand meters high before it rushes out of the water. After rushing out of the water, it must grow several hundred thousand meters high. A tree of this height must be quite thick."

　　 Renne thought.

　　Think about it and know that a tree several kilometers high must be quite thick.

　　 The diameter of the trunk is more than 100 meters. It may be thicker, reaching a few hundred meters.

　　 And Renne still has to think about a problem.

　　 That is whether the tree of the ocean will always grow up. If it grows up all the time, then you have to leave a place.

　　 In addition, there is another important question, is it impossible to put the enemy at the root of the ocean tree to solve it, right?

　　 I must defend against the enemy.

　　 Just like Mermaid Island, it is impossible to put pirates into the island to solve it, right?

　　 What kind of ruin the island?

　　 Therefore, after Rehn swam around the young seedlings of the Ocean Tree on the Whale, he finally decided to build 10 submarine arrow towers one kilometer away from the Ocean Tree.

　　 These 10 submarine arrow towers will circle the ocean tree.

　　 This is the first defensive building.

　　 Behind, Ren will look at the situation and build more defensive buildings.

　　The ocean is a three-dimensional environment.

　　 and it is a rather three-dimensional environment.

　　Unlike land, only a few can fly.

　　 The situation here is different from that of Mermaid Island, and the defense is more complicated.

　　 In Renn's view, the key defense of the Ocean Tree is not these dead defensive structures, but Renn must have enough power to solve all threats.

　　 Well, the main problem is that the defensive surface of the ocean tree is too wide.

　　 Under such a wide defense surface, Rennes, even with a few million gold coins, would not be able to make the defensive structure tightly wrap the tree of the sea.

　　 But basic defense is still necessary.

　　 "The main task is to build 10 submarine arrow towers on the seabed. The reward for the task: 100 experience and 10,000 gold coins."

　　 Ren's decision triggered the main mission again.

　　 just right, a part of gold coins can be subsidized.

　　 Rain began to build.

　　 "The construction is successful, the construction time is 1 hour!"

　　 The sound of the system sounded.

　　 The 10 submarine arrow towers are wound in a circle, and they are not filled with magic bed crossbows.

　　 is similar to the shark gun that humans used to kill sharks in the sea before Rennes crossed.

　　 Of course, the structure is much more complicated.

　　 and it is also an enchanting gun.

　　 Such a gun has a short range on the bottom of the sea.

　　 After all, it’s under the sea...you can't see how far!

　　 Despite this, its effective range is still more than one kilometer, and its penetration is quite amazing. After penetration, there will be a blasting effect.

　　The flame effect is gone.

　　 After setting up the submarine arrow tower, the ocean tree has grown into seedlings tens of meters in height within an hour.

　　 Well, tens of meters high...seedlings!

　　 "This is a seedling?"

　　Rao can't help being surprised when he sees towering trees like...seedlings.

　　 is really a tree of the ocean that can grow thousands of meters high, even the seedlings are so awesome!

Chapter 0027 grows to two kilometers high in three days! Submarine forest!

　　 "Successfully promoted to a seedling, the task is completed, the host gains 40 experience and 4000 gold coins!"

　　 The sound of the system sounded.

　　 "The main task is to upgrade the tree of the ocean to the larval stage, the task reward: 50 experience, 5000 gold coins."

　　 The main task was then triggered again.

　　 Up to now, Renn has roughly understood the cultivation method of the ocean tree.

　　 is not the cultivation of one meter by one meter at the expense of gold coins.

　　 is a stage, a stage of cultivation.

　　 So Ren was nurtured.

　　 It’s not far from Mermaid Island, it’s only a hundred kilometers away, and it’s only an hour’s journey for the Cetus.

　　 Raine built a new building in Mermaid Island, the Mermaid Communication Hut. With this communication hut, Raine can easily pass orders to Mermaid Island.

　　Moreover, with this communication hut, mermaids can also send more information through the mermaid horn.

　　 Raine transferred dozens of mermaids from Mermaid Island to protect the ocean tree.

　　 In addition, Eve also got dozens of killer whales to swim in the nearby sea.

　　 With the submarine arrow tower, the defense is quite tight.

　　 Then Ren concentrated on nurturing.

　　It takes not only time but also a lot of gold coins to cultivate the ocean tree.

　　 Rain did not always stay by the ocean tree, and would go back to Mermaid Island from time to time.

　　The tree of the ocean is divided into several stages.

After the 　　 seed stage, it is the sprout stage.

After the 　　 budding stage, it is the seedling stage, then the mature seedlings, larvae, mature bodies, and complete bodies!

　　The time required for each stage has increased exponentially.

　　 However, although time is constantly increasing, after only three days, Rennes cultivated the sea tree from the seedling stage of tens of meters high to the mature stage of nearly two kilometers high.

　　 The current ocean tree is only a few tens of meters away from the sea.

　　 The 2,000-meter-high ocean tree has a trunk diameter of more than 500 meters. If it is placed on land, it is a standard Big Mac.

　　 Its canopy hasn't fully stretched out because it hasn't flushed out of the sea.

　　 But it is also quite amazing.

　　 The diameter of the canopy is more than a thousand meters!

　　 If you rush out of the sea... it will be even more amazing!

　　 In addition, Rennes also discovered an interesting phenomenon.

　　 That is, with the growth of the ocean tree, a large number of trees appeared on the seabed around the ocean tree.

　　 These trees are not high, only a dozen meters, they cover the seabed that was originally only seaweed, and their area is larger than the canopy of the ocean tree.

　　 Ren found that these trees grew up with the ocean tree.
