It's not very difficult to change the formation base.

First of all, first of all, we had to stop the Zhou Tian Star Dou Great Array, then find the base of the formation, take out two of the high-grade spirit stones, and then embed the two top-grade spirit stones into the formation according to the previous arrangement method.

However, it was just to change the formation base, and Yang Yu also spent more than an hour, this week's Tianxing Dou Great Array was not an ordinary formation after all, there was a slight mistake, maybe the entire Great Array was finished, and he couldn't help but be careless.

After replacing it with a top-grade spirit stone, Yang Yu obviously felt that the entire Zhou Tian Star Dou Great Array was more stable, and the starlight attracted was also more, and invisibly, the power had increased by as much as three percent, which made him very happy.

"The current Zhou Tian Star Dou Great Array, the base of the formation is two top-grade spirit stones, and the array is equipped with three hundred and sixty-five medium-grade spirit stones, if the spirit stones of the array are replaced by three hundred and sixty-five high-grade spirit stones, the power of this array can be increased by at least three times, which is almost enough to resist the half-saints."

A high-grade spirit stone is equivalent to ten medium-grade spirit stones, and it is also equivalent to a hundred lower-grade spirit stones, but in the martial arts, there are really too few high-grade spirit stones, and it is easy to exchange high-grade spirit stones for medium-grade spirit stones and lower-grade spirit stones, if you want to exchange low-grade spirit stones and medium-grade spirit stones for high-grade spirit stones, as long as you are not stupid, no one will exchange them for you.

"Maybe in that crystal palace, there are countless top-grade spirit stones." Yang Yu muttered to himself, a light flashed in his eyes, but if he was allowed to go to the Crystal Palace again, he would not dare to be killed, and the terror of the Nine-Clawed Evil Dragon was enough to discourage him.

Getting up, he looked at the Lingling Lake.

"Big python, whether you can turn into a dragon or not depends on your creation." Yang Yu took out the Neidan he had gotten.

The figure vanished. It's already at the lake.

"Roar!" Feeling Yang Yu's breath, the python came out of the water.

Look at the python. Yang Yu first glared at it: "Next time you dare to steal the spiritual honey, I will have to pull you out." ”

As soon as the python heard this. I was so frightened that I almost got out of the water.

"Okay, don't be afraid, I'm talking about next time." Yang Yu shook his head, "I'm here this time to give you a chance." ”

Python doesn't understand very well?

"Do you see me in your hand?" Yang Yu presented the fiery red inner pill in front of the big python, "This is an inner pill, the effect is extraordinary, and it contains terrifying energy. Here you go. ”

The python's eyes lit up, and he seemed to have an innate sense of Nedan for him, and his intuition told him that Nedan was definitely a divine creature that helped it evolve.

"Roar!"

"Take it!"

Yang Yu threw Neidan over, and the python was extremely excited, swallowed Neidan in one gulp, looked at Yang Yu, and showed a deep gratitude.

"Fight for the Jiao. I've given you too many resources to let me down. After Yang Yu finished speaking, he turned around and left.

If the python wants to completely digest a Neidan, it is definitely not something that can be done in an hour or two. There was no point in him staying here, and the big python looked at Yang Yu's back and was silent for a while. dived into the water.

Three days later, a roar came.

"It's the voice of a python." Yang Yu looked sharply at Shenling Lake. Many disciples also looked there, screaming in this life. It's really too loud.

On the shores of the Lingling Lake.

"Look, there are more and more scales on the python's body, and the bulge on its head is getting sharper and sharper, it must be a fast dragon."

"Excited, my Haotian faction will have a dragon soon, if you say it, it will definitely be a lot of face, see who dares to say that we have no background."

"Jiaolong, if you continue to evolve, then you will become a true dragon, I look forward to the time when my Haotian Sect has a true dragon."

……

Many disciples were watching, even if Yang Yu came, they didn't find out.

"Roar!"

The python endured severe pain, its body hovered in the lake, and a black light flashed on its body from time to time, and there were more and more tiny scales, because of the growth of scales, blood stains appeared in many places.

"Husband, the evolution of the python into a dragon is estimated to be something that has not been encountered in a thousand years, and after evolution, the python should have the strength of a god-level martial artist." Tang Wei appeared behind Yang Yu.

"Yes." Yang Yu nodded, "The reason why I didn't kill the python in the first place was because I felt that its future was limitless, and the dragon was just the first step, maybe one day, it could really evolve into a real dragon." ”

"Husband, let's not say if it can evolve into a real dragon, but the skin it sheds now is a treasure." Tang Wei smiled, this seemed to be the purpose of her coming.

"Skin, baby?"

"The skin shed by the python, the first use is to make it into a defensive inner armor, which is very comfortable to wear on the body and can resist general sword attacks, and the second use is to refine medicine, after crushing, it is made into powder, which has the effect of stopping bleeding and refreshing." Tang Wei explained.

When Yang Yu heard this, he didn't feel a little moved, he looked at the python, every time some scales grow, the outer skin falls off a little, and the body of the python is very large, but in the past ten minutes, the skin that has fallen off is enough to make a few inner armor.

"Roar!"

The python screamed again, and many scales grew out at an accelerated pace, and gradually, its whole body became darker and darker, and every inch of black was an inch of scales.

After an hour, eighty percent of the python's body had turned jet black, and the scales were getting denser and denser, but Yang Yu could clearly feel that the python was struggling, and it seemed that evolution had encountered a bottleneck.

"The energy required for the evolution of the python is too huge, husband, do you still have an elixir spirit stone or something? Anyway, as long as it can provide energy, give it to it, otherwise I'm afraid it won't be able to evolve. Tang Wei suddenly spoke.

Yang Yu was stunned: "Okay, if you can't complete the evolution this time, it will be a failure." ”

Thinking about it, Yang Yu grabbed a handful of spirit stones and threw them over.

The big python noticed Yang Yu's movements, and sucked it violently, sucking the spirit stone into its mouth, just swallowing the spirit stone, its evolution seemed to be three points faster.

"This ......" Yang Yu was surprised, the big python used to be in the spirit stone mine, but at that time, where did it have such a speed to absorb spiritual energy.

"When it evolves, the python is in dire need of energy, and its body can absorb energy a hundred times or even a thousand times, which is just a kind of self-adaptation of living beings, just like when people are hungry, the speed of eating will be much faster unconsciously." Tang Wei explained a little.

Zhilu said this, Yang Yu didn't care, and threw a lot of spirit stones over, even the Yuan Spirit Pill threw over a dozen, but it didn't seem to be over yet, he threw over all the Yuan Crystals he had obtained before.

The python is like a greedy snake, it seems that it is addicted to eating, and it doesn't even want to evolve, and its eyes keep looking at Yang Yu.

"What else do you see, if you can't evolve today, I'll stew you at night." Yang Yu shouted.

When the python heard this, he was startled.

The surrounding disciples were also stunned, taking a big python that was about to evolve into a dragon and stewed soup, isn't this too tempting, and some disciples even hope that the big python will not evolve successfully, after all, such a snake soup is really not tasted.

I don't know if what Yang Yu said is true, the python is now full of strength, and the scales on its body are covered by ninety-five percent in a blink of an eye, and there are less than three breaths below, which is already completely covered, which indicates that the evolution of its scales has been completed, and now the most important thing is the skull.

The python felt very itchy on its head, as if something wanted to get out, but after a long time, it still found that it couldn't work.

"Damn, if I raised you waste, I really lost my home." Yang Yu looked at the big python, "This is a top-grade spirit stone, swallow it for me!" ”

The python was stunned, looking at what Yang Yu threw over, he was immediately overjoyed, he didn't want to think about it, he swallowed it in one gulp, and then a huge energy filled his body, and this energy quickly gathered together, and then reached the top of his head.

"Edict!"

Something came out of the skull, the python hadn't seen it yet, but the people of the Haotian Sect around it could see it clearly, it was a long black horn, this horn exuded black light, and there was a momentum that pierced the blue sky.

"Whew!"

The python roared in the sky, and its whole body seemed to react coherently, first of all, the most obvious was that its mouth grew long fangs, its head became more and more pointed, some long black whiskers appeared on the side of its mouth, and four black claws poked out from under its body.

"Evolution has worked." Yang Yu muttered to himself.

Tang Wei nodded: "It's a success, this is the dragon, although in ancient legends, the dragon has many appearances, but the real dragon is like this, because it is not a real dragon, it is only a single horn now, and when it evolves into a real dragon, the single horn degenerates and grows double horns, and the four claws under the body will also evolve into five claws." ”

The python also noticed the change in itself, it was overjoyed, and was about to roar a few more times, but suddenly it felt numb on its body, and then found that the muscles of the whole body began to contract, and the huge body shrank by one-third in just a blink of an eye.

At this point, evolution is completely complete.

"Yes, python...... Now I can't call you a python, look at your appearance, you are black, very powerful, I will give you a name, called Black Wind! Yang Yu said.

Tang Wei couldn't help but laugh secretly, this name came from, the vampire god bat was called Black Ball, and a dragon was called Black Wind, which was really blind enough, but the big python didn't know whether it was good or bad, but when he heard Yang Yu name it, he hurriedly roared a few times, and agreed first.

"That...... Black Wind, just evolved, show us our hands. Yang Yu thought about it, and the disciples around him were already looking forward to it.

The python understood what Yang Yu meant, and its body jumped suddenly, rushing directly out of the water, bounced towards the sky, dozens of zhang high, and just when others thought it was going to do something, it fell from the air rapidly, and its tail was pumped on the surface of the lake.
