11 Energy Tower Defense Network

Peter walked to the center of the island, where a special device was floating. Not only was it responsible for the transportation to the outside world, it also had a 3D model of the island.

The island was 20 km long and 18 km wide. To build an energy tower defense network, a more accurate fixed-point plan was needed.

It was different from ordinary fortifications. The uniqueness of the energy defense towers caused each energy defense tower to have a crossing point in the distance between each other.

In other words, when the two energy defense towers were 1 km apart, blind spots were eliminated.

However, if there were three energy defense towers, in order to maximize the attack range, the blind spot would appear at the center of the three energy defense towers.

Some people would say that no matter which angle the enemy attacked from, they would not be able to reach the blind spot. This was theoretically true, but Peter was not clear about the unknown enemy. If a sea monster relied on a very thick defense and passed through the attack range of the energy defense tower, it would reach the blind spot and could deal a fatal blow to the energy defense tower.

The entire defensive net formed by the energy defense tower would be destroyed.

This was the situation that Peter was most unwilling to see.

For safety reasons, he planned to go along the border of the island and use the hexagons as the foundation to form an airtight defensive net around the island.

An energy defense tower would be erected at every point of the hexagons, and a separate energy defense tower would be erected at the center of the hexagons. This is the best plan that Peter has come up with so far.

Just do it.

Peter opened the tree of life interface. It turns out that the tree of life was able to produce five tree spirits a day, but now that the tree of life has been upgraded, it can now produce 10 tree spirits a day.

With the previous production of five tree spirits, a total of 15 tree spirits can be used.

Peter immediately produced 10 tree spirits in the tree of life interface.

After a short wait, the 10 tree spirits were produced.

There were already 15 tree spirits in the tree of life. Peter summoned all 15 tree spirits at once.

The 15 tree spirits followed Peter in the direction of the beach.

On the way to the beach, Peter distributed the tools that he had brought in previously to the tree spirits.

They were mainly tools for surveying and positioning. This was what most humans who entered the island had to carry.

Because the size and shape of the island that each person was assigned to was different, it was said that someone had been assigned to a long strip of island before. As a result, after the protection period, they were unable to defend against the sea monsters' attacks.

This mainly depended on the terrain. The only thing that could be blamed was that guy's bad luck.

In fact, an oval-shaped island like Peter's was not the best shape.

The best defense shape was a lake-on-an-island-in-a-lake-on-an-island, a shape like a big doughnut with a small doughnut inside.

However, Peter's Island shape was pretty good.

Half an hour later, Peter led 15 tree spirits to the location of the beach and personally led 15 tree spirits to draw a hexagonal pattern, then locate the six points of the hexagonal mark. Then, through a simple measurement, they can find the center point of the hexagonal mark.

The Tree Spirits' IQ is very high, so they basically only need to be demonstrated once to learn the use of various measuring instruments.

After that, it was simple. Peter just needed to follow behind the 15 tree spirits and supervise their work. He was afraid that a mistake at a certain point may cause delays when he built the energy tower defenses.

The 15 tree spirits were very efficient. Before the sky turned dark, they had planned out all the predetermined locations of the defense network.

Now, he would have to wait for the construction of the energy defense tower.

Peter led the tree spirits back to the tree of life and watched as the 15 tree spirits lined up and entered the trunk of the Tree of life.

He immediately opened the interface of the tree of life to check the life energy.

[ tree of life ]

[ level ] : 11/100.

[ life energy ] : 2,650 points. [ life energy can be used to nurture and level up creatures. 300 life energy can be used to nurture a creature. ]

[ daily output ] : 1,100 points per day.

[ tree spirit ] : 11 points per day. [ short tree spirit, very good at planting all kinds of plants. ]

[ energy defense tower ] : construction requires 500 life energy points and 100 units of Energy Crystals.

Peter saw that the tree of life had produced 2,650 life energy points.

Apart from the mermaid and killer whale points, there were still 2,500 life energy points. This was enough to build five energy defense towers. However, to build five energy defense towers, another 500 units of energy crystals were required. This required the mermaid to enter the bottom of the lake to mine, and this time it'll take more time.

Peter walked to the lakeside. He originally wanted to see how many energy crystals the mermaids had mined. However, the scene that appeared by the lakeside shocked him. At this moment, the lakeside was piled up with energy crystals that were the size of small mounds.

Were these all mined by the Mermaids?

Peter looked at the lakeside with doubt. Just then, a tiger-like little guy came out of the lake. There was a sparkling energy crystal in its mouth, and it quickly swam to the shore.

Was this an orca?

Before Peter led the tree spirit to the beach, he specially ran to the lake and fed the mermaid and orca with life energy. Who would have known that after only leaving for one afternoon, the orca's body actually grew to three times the size? This growth speed was too terrifying.

The orca also recognized Peter. It spat the energy crystal in its mouth onto the energy crystal piled up by the lake. Then, it turned around and called something with its mouth. It was the killer whale calling the mermaid.

Not long after, the little head of the mermaid appeared on the lake, with an energy crystal in each of her hands and the mouth. Seeing Peter standing by the lake, the mermaid quickly swam over.

Peter knelt down on one knee and looked at the mermaid who kept swimming closer. He was also quite surprised.

This mermaid had grown a lot.

Before, the mermaid was about 40 centimeters long. Looking at it now, the mermaid was definitely more than 60 centimeters long.

The mermaid swam to the lakeside and threw the energy crystals in her hands onto the lakeside. Then, she threw the energy crystals in her mouth onto the lakeside as well.

Pop! Pop!

"The Crystals... are all here."

Peter looked at the mermaid and was very happy.

The killer whale beside the mermaid also shook its head and spoke something like "ou ou".

The mermaid continued, "It said... that it put in some effort."

? ? ?

Peter was surprised when he heard the mermaid's words. "You can understand what the killer whale said?"

The mermaid tilted her head and replied, "Yes!"
