The ecological environment of Jinlei is also specially built for the Seventeen Breakthroughs, and the ecological secret room temporarily built with a variety of gold and thunder materials has been prepared by Lin Heng since ten days ago.

"Thank you, senior sister, please help guide me."

Lin Heng nodded, took the liquid medicine and began to operate.

"Don't worry, your cultivator talent is still very good." Senior sister Chen Youlan said with a smile, standing in the distance and watching quietly.

She is wearing a canary cheongsam today, and her delicate and qualitative body curves are addictive, especially the slender jade legs revealed at the slit of the cheongsam, which makes people feel thrilled.

She didn't mean to wear it like this, but Lin Heng came too suddenly, and she didn't have time to change it, so in order not to distract Lin Heng, she also put on a small white shoulder before coming in.

Lin Heng nodded and began to operate seriously.

Since a month ago, Lin Heng had let Seventeen start eating the gold-based materials containing thunder and lightning, and with the active chestnuts that he had been eating, the environmental foundation in his body had been established.

There is also a specially built Golden Thunder Ecological Secret Room outside the body, which is full of gold and thunder aura.

"Seventeen, you're squatting here!"

Lin Heng pointed to the small pit in the center of the secret room and said, this is specially made.

"Woohoo! (๑*◡*๑)”

Seventeen walked in with some excitement, crouching inside, half of its body soaked with the spiritual fluid in the pit.

Lin Heng then added three kinds of medicinal liquids to it, and then asked Seventeen to take five kinds of mixed medicinal liquids orally, these medicinal liquids were all made of finely ground spiritual materials, and they were almost as thick as syrup.

As Seventeen drank the main ingredient, the evolution began after about three minutes, and the dark blue liquid in the puddle was absorbed by it and wrapped around his body, flowing rapidly.

Seeing this scene, Lin Heng hurriedly poured the last three catalytic liquids into it, and soon Seventeen was enveloped by a light enchantment that emitted white and purple.

A temporary light film barrier was formed, enveloping it in an enclosed space, and the aura of the ecological secret realm was continuously absorbed.

Seeing this scene, Lin Heng retreated and waited quietly, the next thing was not something he could interfere with, the imperial beast would temporarily enter a wonderful state, and it could not be snooped on and interfered with, otherwise it was extremely easy to fail.

Looking at the light film enchantment, Lin Heng exhaled deeply, for the breakthrough of the seventeenth, a lot of preparations were made before and after, the construction of the ecological secret room, the creation of the internal environment, and the preparation of various materials, the total cost reached three million, which can be said to be extremely luxurious.

This is also the reason why the beasts cultivated by humans are much more powerful than wild monsters, and the human beast masters have already made this kind of preparation.

The evolution of the beast in the wild is often fateful, and it is often a matter of devouring a certain material that is conducive to evolution and then suddenly starting to evolve.

The internal and external environment is not created, the possibility of failure is extremely high, and it is also easy to be affected by other breaths, and various distortions appear.

Seeing Lin Heng's anxious appearance, Senior Sister Chen Youlan gently patted him on the shoulder, and said with a smile: "Don't worry, there's no problem, Senior Sister has experience." ”

Lin Heng nodded, the evolution of the imperial beast was not completed in an instant like in the animation, the higher the potential and the higher the level, the longer it would take for the imperial beast to evolve.

Like the seventeenth level of the minion level, the existence of the potential inferior grade, the evolution is about three hours.

Lin Heng and Senior Sister chatted while waiting, and even meditated for a while because they were too bored.

Finally, when the sun was about to set, the light film barrier changed, and purple thunder shot out from it, and a beast shadow slowly moved.

"Whew!"

Three minutes later, the purple thunder and lightning tore through the light film enchantment, and after completing the evolution of the race, the seventeen revealed its body, it shook off the spiritual fluid on its body, and rushed towards Lin Hengfei, with a happy expression on its face.

Master, I'm done evolving!

Seventeen's current appearance is very different from before, its size has become larger again, not counting the tail body length is three meters, and the height is one meter five, which looks bigger than the tiger on the earth.

The hair on the body is purple and white, not a chaotic arrangement, but a very beautiful distribution, the original brown hair on the front and rear legs has turned purple, which can be called purple clouds stepping on snow.

There are not many purple hairs in other places, but they are very appropriately embellished, especially the purple electric flashes from time to time, which looks full of a sense of nobility.

In addition, its eyes have also transformed into purple pupils, in which electric light wanders, and there is a sense of mystery and majesty.

Between running, its body emitted two kinds of faint glows, purple and gold, the purple one was full of a kind of thunder and lightning power, and the golden one was extremely sharp.

There is no doubt that it has successfully evolved into a Purple Electric Swordtail Sable, and its rank has been successfully promoted to the Commander level.

The crystal nucleus has been born in the body of the commander-level imperial beast, and with the source of power, it is much stronger than the servant-level in all aspects, and the current seventeen can be beaten by ten previous servant-level seventeen, and it is the effortless kind.

"Hahaha, very good, good, seventeen is amazing!"

Lin Heng said with a smile on Seventeen, who was bigger than a lion, and took out two more spirit fruits and fed them to it.

Seventeen's hair is a little better than before, and his current size is completely suitable for him to ride.

At the same time as the seventeenth breakthrough, he felt a huge force of feedback entering his body, making him feel like he was bursting, and these forces were constantly transforming his body and strengthening his soul.

"Whew!"

Seventeen, like a child, told Lin Heng about his changes in his heart, and according to it, the biggest change was the gold-devouring space in his body.

With its evolution this time, the gold-devouring space has completely fused with its stomach, which is equivalent to raising its proficiency to the proficiency level.

Eating will automatically fall into the gold devouring space digestion, and you can also devour some less powerful skills, or you can control the gold devouring space not to digest, as a temporary storage space.

What's more, it seems that because of the increase in the thunder attribute, there is also some kind of abnormality in the gold-devouring space, and the inside is filled with thunder and lightning, which has become a digestive juice for digesting food.

"Very good, very good!" Lin Heng nodded again and again, and warned it in his heart not to show it, the gold-devouring space could not be exposed for the time being.

This change surprised him too, according to Seventeen, this evolution should also allow Seventeen to include the gold-devouring space and evolve into a part of the body.

"This purple electric swordtail marten of yours has actually reached the limit of the middle grade, which is really unusual."

Senior sister Chen Youlan on the side has also been observing Seventeen, and at this time she also stretched out her hand and touched its soft fur and said.

After the evolution, Seventeen surprised her, it was far more perfect than she expected, just by looking at the amount of spiritual power gathered around it, she could judge that its spiritual power affinity was close to 60%.

This is the spiritual power affinity that only has the ultimate potential of the middle grade, and in addition, its size is also much larger.

Even if the Purple Electric Sword Tail Sable is much better than the Electric Light Sword Tail Sable, the expected potential is only at the middle and upper level of the middle grade, and it cannot reach the limit.

And judging by her intuition, this evolved purple electric swordtail marten seemed to be far more than this change, and it seemed that there was a deeper change that led to the increase in potential so much.

It made her want to dig deeper, but in the end she held back. Although Lin Heng is her junior brother, the relationship between the two has not yet reached the point where it can be discussed in depth.

"Haha, it may be the effect of the blood vein purification in the cracks of the Lingquan and Jinmu spaces, and it is said that the skills of the transformation realm level are also conducive to the increase of potential."

Lin Heng laughed, pretending not to know at all.

"If you succeed, you'll be able to soar into the sky in the future." Chen Youlan patted Lin Heng's shoulder and said with a smile.

With the current level of the Purple Electric Sword Tail Mink, as long as it grows normally, Lin Heng will be the worst in the future and will also be a Pavilion Master-level Beast Master.

The first beast is often decisive for the future of the beastmaster.

"Thank you Senior Sister for your help these days, no matter how high you fly, you are still a good senior sister I respect." Lin Heng also said with a smile

He was very happy, seventeen breakthroughs, he already had the initial strength to break into the wilderness, no longer have to be confined to the city.

"That's right, senior sister likes to listen, let's go out and celebrate, Yiyi has already prepared food."

Hearing this, Senior Sister Chen Youlan said with a smile, feeling that Lin Heng had a sweet mouth and was very good at talking, and she was very satisfied.
