CHAPTER 530: CHAPTER 390: ARMED UPGRADE OF THE OIL RESOURCE POINT! OWNER OF 160 ROBOTIC DOGS_2

About ten meters from the city wall, Lin Yue began construction again.

This time, however, he was building the initial type of wall, 35 centimeters thick and three meters high. This type of wall did not require any guard machine gun platforms for defense, only needed to be tall enough.

Surrounding the city wall, Lin Yue quickly established a new circle of walls, and within the area of these walls and the city wall, just like inside the city wall, he laid a layer of stones.

The main purpose of doing this is to prevent Lizardmen and beggars from digging tunnels within to attack from the inside.

Having done all this, Lin Yue brought out 20 remaining machine dogs from before.

Moreover, Lin Yue individually upgraded each of these machine dogs with a sniper rifle, with a bullet count of 30 rounds.

The role of sniper-type machine dogs is significant, and Lin Yue also believed they could easily pull off a headshot on the enemy from a great distance!

To facilitate their sniping, Lin Yue also set up some slopes between the outer walls and the ground to allow these machine dogs to patrol and snipe directly!

Lin Yue set and edited their patrol routes and strategies when encountering enemies, which took a bit of time.

Afterward, he tirelessly manufactured 40 machine dogs!

These machine dogs were equipped with double MP5 submachine guns, responsible for close to mid-range sweeping and guerrilla warfare when the medium electric guard machine gun platform goes silent, or when the Lizardmen break through.

In this way, with the combined cooperation of the medium electric guard machine gun platform and the machine dogs, the defense at close, mid, and long distances was essentially problem-free.

"The only thing left is building the Doomsday Bunker and going back to bring over the Little Ice Lizards, and then..."

At this moment, the system suddenly emitted a sound!

[Congratulations, you and your pet have established an emotional bond, and your pet has undergone bond evolution!]

Hmm? Evolved? Who?

[Congratulations, you and your pet have established an emotional bond, and your pet has undergone bond evolution!]

[Congratulations, you and your pet have established an emotional bond, and your pet has undergone bond evolution!]

[Please confirm pet information]

[Please confirm pet information]

[Pet Species: Scythe-Blade Flying Lizard]

[Pet Name: Green Claw]

[Status: Adult]

...

Ah this.

What’s going on, how did these two lazy little guys level up?

What’s more, it’s bond evolution? What did I do? Clearly, there’s still dozens of kilometers to the Nitrate Ore mine, right?

Feeling odd and surprised, Lin Yue looked at the species information of these two little guys and roughly guessed their state.

Even without seeing the two, he could distinguish that one should be running on land, and the other flying in the sky.

Just like Bai and Meng, just like Liuzzi and Hongxian, they all evolved in pairs.

The ones with flight specialization usually have some speed and attack buffs, whereas those running on land have decent endurance and stamina.

However, there is also a problem.

"Bai, Meng, Dark Spot, Green Claw, Liuzzi, and Hongxian, there are actually six evolution branches? Just the evolution is already outrageous, and now there are six evolutions? The remaining Little Ice Lizards number five hundred, does that mean there are five hundred types of evolution?"

Lin Yue still had a lot of misunderstandings about this world, especially the evolutionary state of Ice Lizards, which left him completely puzzled.

After all, there can be no evolving creatures on Earth, at most there is the transformation of caterpillars into butterflies, an occurrence unique to insects, and from all appearances and even their name, the Little Ice Lizards seem more like vertebrate reptiles.

Yet they have indeed evolved. Though he did not witness the evolution of Dark Spot and Green Claw, he witnessed the entire progress with Bai and Meng.

After two continuous evolutions, there was another state evolution known as "molting," but so far only Bai achieved this, Meng has not shown any signs, nor did any other similar situations arise.

"However, it seems there will be three flying champions, maybe more tactical options in the future."

Lin Yue had no dissatisfaction with the evolution of Dark Spot and Green Claw; it unwittingly turned into a stroke of luck, just some unexpected occurrences.

He was quite curious about how these two little guys managed to conceive the possibility of bond evolution, considering previously all bond evolutions were tied to some "special opportunity."

For example, the first evolution of Bai was due to accumulating a lot of combat experience from multiple actions with him, and after a long period of living together, the relationship became closer, leading to the final evolution.

And the second instance of bond evolution of both Bai and Meng was indeed connected to "mutual rescue in times of crisis."

During that occasion with Bai, he was incapacitated due to a high fever, and Bai stood forward to eliminate a large number of enemies, then successfully evolved afterward.

Meng went into the Underground Ruins, was injured heavily covering Dark Spot and others when attacked by Lizardmen’s explosives. He spent huge efforts saving Meng’s life and took revenge inside the Underground Ruins.
