Gu Yuan carefully observed the dragon egg in his hand.

I saw that the dragon egg was similar in size to his head, and the whole was similar to an oval shape with a narrow top and a wide bottom. The base color of the dragon egg is milky white, and it is covered with tiny granular crystals. Trembling slightly, the dragon egg exudes a strong breath of life.

Gu Yuan nodded with satisfaction.

Very good, it is a dragon egg that still retains its vitality, Zhao Guoyi did not take a dead egg to pit himself.

【Crystal Dragon Egg】

Status: To be hatched

Hatching conditions: 200,000 energy, A-grade three-leaf emerald grass, A-grade phoenix perch, B-grade dragon's blood altar......

Well, as the legend goes, every dragon is the crystallization of a huge amount of resources, and if the family is not rich enough, even hatching dragon eggs is a difficult thing to do.

But fortunately, Gu Yuan didn't think about hatching the dragon egg when he bought it, and he couldn't muster the resources needed to hatch the dragon egg at this stage.

He carried the dragon egg to the only sixth-level arrow tower so far, and used the long-acquired skill on the arrow tower: the Bloodthirsty House.

[Hint: Please choose the monster corpse used to transform the sixth-level arrow tower.] 】

Gu Yuan chose the crystal dragon egg he was holding.

[Judgment ......]

[Judgment passed!] 】

[Congratulations, you have discovered the hidden usage of the A-rank skill Bloodthirsty House!] 】

[Although the Bloodthirsty House in the skill introduction needs to transform the building with corpses, in fact, living creatures are also possible!] 】

[It's just that the transformation of corpses is based on buildings, while the transformation of living bodies is based on living organisms!] 】

[Do you use the sixth-level arrow tower to transform the crystal dragon dragon egg?] 】

Sure enough, the dragon eggs with the activity can be used as materials for renovating buildings through systematic judgment.

All this was expected by Gu Yuan.

He chose yes.

[Please add two more attacking buildings and one building with flying ability, the level and quality of the sixth-level arrow tower are too low to undertake the transformation of the crystal dragon dragon egg.] 】

This piece of information greatly surprised Gu Yuan.

He knew that the dragon egg was very tall, but he didn't expect it to be so high, and even his current sixth-level arrow tower couldn't withstand the transformation of the dragon egg.

Now it's going to be difficult.

The two assault buildings are good, and the Secret Shop has blueprints for the Turrets and Mage Towers.

But where do you get a building with the ability to fly in the air?

Whether in a past life or in this life, buildings with the ability to fly are undoubtedly rare.

Perhaps such an existence can meet the personality needs of the dragon egg transformation.

It was at this time that the group of farmers who built the farmhouse finished their work.

It will take more than an hour to build the Hero Altar, after all, the altar takes more time than the farmhouse.

"No matter, I'll knock on a turret first."

Gu Yuan gave the order, and one group of peasants continued to build the farmhouse, while the other group of peasants followed him to the secret shop.

He himself entered the interior of the tavern-style mystery shop and chose to buy it.

[Congratulations on purchasing the Heart of the Black Iron Machine, which consumes 10,000 energy, and now has 10,450 energy points left]

[Congratulations on purchasing the turret crafting book, which consumes 1000 energy and 9450 remaining energy]

[Congratulations on purchasing the Mage Tower Crafting Book, which consumes 1000 energy and 8450 remaining energy]

After buying these, Gu Yuan's remaining assets were less than 10,000 left, and he urgently needed a little blood now.

So Gu Yuan continued to buy the well of lv1, made the book in the warehouse, and then threw it in the forum to be auctioned.

Eventually, the well was sold for a whopping 5,000 and was bought by a local tyrant whose initial location was in the desert.

The warehouse production book was sold for 7,000 energy, and the buyer did not disclose his identity information.

Gu Yuan returned a large wave of blood fiercely, and the total amount of energy returned to 19950.

Incidentally, the inventory of the Mystery Shop was emptied, and the Mystery Shop disappeared in a burst of white light.

"Hey, it would be nice if the goods in the Secret Shop could be purchased repeatedly, so that you can make a lot of money by taking the goods from the Secret Shop and auctioning them in the forum."

Unfortunately, the system has long since put an end to this behavior, and has set the Mystery Shop as a one-time purchase location.

Gu Yuan sighed and asked that group of peasants to start building turrets next to the arrow tower.

Five peasants gathered around the tower, banging and beating, and soon, a square base slowly took shape.

[Lv1 Turret]

Status: Under construction (30 minutes to build)

Attack Type: Area of effect group damage, with explosion splash damage

After assigning the task, Gu Yuan returned to the arrow tower, if it was not what he expected, Gu Yi should have completed the domestication of the nine little wolves at this time.

Pushing open the heavy wooden door of the arrow tower, what greeted me was a strong man sitting cross-legged on the ground.

The strong man had knotted muscles, exuding a savage and primitive aura around him, and was surrounded by nine wild wolves that were also strong and primitive.

The strong man's facial lines were rough and soft, but a claw mark that spread from his left eye to his chin broke this soft temperament, adding a touch of fierceness to his appearance.

The gate was suddenly pushed open, and the light poured in, and the nine wild wolves beside the strong man were obviously frightened.

Their tails hung low, tucked between the two thighs of their hind legs, their heads slowly raised, their mouths grinning, their sharp canines glistening like metal.

"Roar—"

The nine wild wolves made a demonstrative, low voice in their throats, as if warning Gu Yuan not to set foot in their master's territory.

At the same time, nine wild wolves surrounded the strong man, faintly protecting the strong man, like nine loyal dogs protecting the lord.

At this moment, the strong man shouted: "Stop! This is my master, don't be presumptuous! ”

Then he stood up from the ground with his legs propped up, and rushed to Gu Yuan in a few steps.

With a bang, the sturdy body knelt down on one knee like pushing a golden mountain and a jade pillar, and the right fist hammered into the left chest.

"I've seen the master!"

A thunderous sound came from his throat.

Gu Yuan was delighted to find that Gu Yi had undergone this amazing change, but for some reason he had gone through a process of domesticating a little wolf, but Gu Yi was able to transform to this point.

He flipped through the previous system prompt and suddenly realized.

It turned out that when he gave himself the first reward for activating the retainer system, he not only helped Gu Yi improve his innate ability, but also gave Gu Yi a chance to fully evolve.

It seems that the process of taming the wolf cub catalyzed this evolution, making Gu Yi take another big step in the direction of a druid, an animal trainer.

Gu Yuan opened the attributes of his retainer Gu Yi.

[Retainer: Gu Yi lv5]

Status: Healthy (100/100)

Occupation: None

Defense: 10 (Light Armor)

Attack: 10

Loyalty: 100 (Retainer loyalty locks 100 and does not decrease)

Talents: A-level Heart of Nature Lv1: Can communicate with any kind of pets and mounts, can communicate with most beasts, greatly increases the success rate of domestication skills, and greatly increases the affinity for neutral creatures

A-level Co-Prosperity and Co-Loss Lv1: After taming a pet or mount, Gu Yi can obtain one of the abilities of the pet or mount, and can catalyze the pet or mount to rapidly evolve to adulthood

Skill: lv1 domestication: Able to tame monsters and neutral creatures with the highest level no more than themselves, and the taming power is related to the strength of the tamed object.

Lv1 Frenzy: Releases a Wild Warcry that decreases intelligence, but increases attack speed and attack power

It seems that that the brand-new A-level talent co-prosperity and co-loss is the reason why Gu Yi has changed so much. After taming the nine little wolves, he not only inherited the beast physique of the little wolf from the little wolf, and his physical attributes were greatly strengthened, but he also obtained the bloodline inheritance ability of the little wolf and became crazy.

The wolf cub also benefited from a gift and quickly developed into adulthood.

Gu Yuan glanced at the little wolf's attributes.

[Pet: Wolf Lv3]

Status: Healthy adult (20/20)

Defense: 1 (No Armor)

Attack: 5

Talent: C-level Heart of Nature Lv1: Able to perceive the power of nature and grow and evolve slowly

Skill: Lv1 Frenzy: Sends a wild battle cry, reduces intelligence, but increases attack speed and attack power

Lv1 Claw, Lv1 Tooth: Increases the damage of claws and canines

The attributes of a single wolf cub are naturally inferior to Gu Yi, but the nine wolves together are also a huge force that cannot be ignored.
