"It's!"

Shen Lian was shocked.

At this moment, he suddenly had a mental connection with the Iron Skin Gu.

Actually, this refining has been successful!

The next moment, the Iron Skin Gu burrowed under his skin and turned into a cold air current that swam through his body, all the way to the elbow.

The wonderful thing was that Shen Lian could see what the Iron Skin Gu was doing.

I saw that the iron skin Gu came to a closed hole, arched forward, and after breaking through a layer of membrane, the hole opened.

The Iron Skin Gu entered the acupoint and began to shake its body non-stop, secreting a slimy liquid, and then, the liquid bulged up like a balloon, turning into a perfect hollow sphere, and the liquid solidified and turned into a transparent film of light.

The whole process is like building a nest!

The Iron Skin Gu was inside the hollow sphere.

"This, isn't this just enlightenment?"

Shen Lian hurriedly took out the book from his arms and turned to one of the pages, his eyes getting brighter and brighter.

"After the initial Gu refining is successful, the Gu will sneak into the host's acupoint, open the aperture and build a nest, and the hollow sphere formed is called the aperture, which is a different space opened up by the Gu to store vitality. ”

Yes, it's enlightenment!

Only when the hole is opened, the empty hole is born!

"Haha, I'm free!"

In fact, with enlightenment, there is a real difference from mortals, and only then can it be regarded as a Gu master in the true sense.

Shen Lian felt that as the Iron Skin Gu exhaled in the void, something in the body was being refined, extracted, and attracted, with the void as the center, forming a vortex that resembled a black hole, and a trace entered the void.

After these things entered the void, they were like thin mist drifting, lingering around the Iron Skin Gu.

"Genki, this is Genki!"

Shen Lian's spirits were greatly lifted, and he felt that he was finally on the right path.

At the same time, he also wondered why the Hip Gu didn't open his way to build a nest, and he also made a hole for himself.

Just when he was confused, the Hip Gu suddenly broke into the hole of the Iron Skin Gu.

The man looked around as if he had been a master, as if he had built the void, and lay down lazily.

In this regard, Iron Gu had no opinion at all, but welcomed it.

The two Gu lived happily together like this.

Shen Lian was extremely speechless, and found that the Hip Gu was not an ordinary scoundrel, and he was a bit of a bully who jumped out of the Three Realms and was not in the Five Elements!

Also, the book says that Gu's character is like a wolf, very tenacious, unruly, the refining process is difficult, it is not a day's work, and some Gu with strong intentions will take several years to refine successfully.

For example, this Iron Skin Gu, the average refining time is three months, and it takes a hundred days of blood to succeed.

The Hip Gu quickly tamed the Iron Skin Gu and helped Shen Lian succeed in refining in an instant, this ability was really against the sky!

It's good to be reverse!

Shen Lian is sure and sure, he has picked up the treasure!

Frolicking Gu, it is definitely a very awesome Gu!

At this time, he noticed that the interface had changed, and there was more information.

Written:

Iron Skin Gu, White Level, Special Effects, Iron Skin.

Consuming 2 points of bewitchment points, you can make the Iron Skin Gu evolve by one level, does it evolve?

Shen Lian was stunned for a moment, then read it carefully, and then he flipped through the book, and a look of ecstasy gradually appeared on his face.

In particular, Gu is a strange existence that can evolve indefinitely.

Of course, the path of evolution is very bumpy, even under the most optimal conditions, in the hands of Gu masters with the most superb Gu refining skills, the probability of failure is still very high, and the probability is amazing!

Shen Lian had learned a little bit of biology in his previous life, so he naturally knew the difficulty of biological evolution.

It may take millions of years for an organism to evolve to its current height, and with the development of biology, humans have mastered some technologies that can speed up biological mutation, such as ultraviolet radiation, chemical mutagenesis, etc., and even directly manipulate genes, such as making rabbit hair fluoresce at night, genetically modified food, etc.

But these variations and trimmings are the result of a lot of experiments.

The emergence of a mutant microorganism may stand out from millions of compatriots, and its appearance means the failure or even death of millions of compatriots.

Evolution Gu is different, there are not infinite Gu Formations, there are only one or that Gu Masters in their hands, and the failure of Evolution means a huge loss, so this is a battle that is all in one battle.

For example, this Iron Gu, in order for it to evolve, it must be mixed with a small amount of mercury and crane top red in its food, that is, refined iron, and continue to feed it for more than three years in a way similar to chemical mutagenesis, then it will have a one-third probability of successful evolution.

But if it hasn't evolved after five years, the side effects of taking mercury and crane top red for a long time will break out, and the iron skin Gu will definitely die.

And Gu Masters have been with them for a long time, and the toxins of mercury and crane top red will also slowly seep into the body, and the impact on Gu masters can be imagined, many Gu masters have been poisoned in Gu refining.

The danger of the road of evolution can be seen from this, and if you don't succeed, you will become benevolent.

"In three years, how much refined iron, mercury and crane top red have to be consumed, and so much money has been spent, and the success rate is less than fifty percent, the life of the Gu master is not easy to mix. ”

Shen Lian somewhat understood why Lin Xiuping was in a hurry to sell the Hip Gu, a Gu that he couldn't use himself, instead of keeping it on his body, it was better to sell it for money, he was really short of money.

"And so, but it fulfilled me!"

Shen Lian focused his attention and imagined a finger heading towards the interface point.

"Evolve Iron Gu!"

Immediately, the interface flashed, and the bewitchment value quickly changed to 0.

At the same time, the Iron Skin Gu trembled violently, as if it was experiencing great pain brought about by its transformation.

And so on for about an hour.

The Iron Gu finally stopped trembling, and at first glance there seemed to be no change, only a bronze pattern appeared on its back.

Shen Lian quickly flipped through the books, and when he saw it, he couldn't help but be overjoyed.

"After the white-level Gu evolves, there will be more bronze stripes on its body. ”

Shen Lian looked at the interface again.

It reads:

Iron Skin Gu, Bronze Level 1, Special Effect, Iron Skin, Strengthens Physical Fitness

"Sure enough, it has evolved, and there are new special effects. ”

Shen Lian felt it for a while, the speed of the Iron Skin Gu refining vitality was significantly faster, before it was a trace of refinement, but now it is a wisp of refinement, it is not the same, the bronze level is much stronger than the white level!

He continued to open the book.

"The book says that the level of the Gu Master is determined by the Gu Master with the highest level of Gu Master.

I'm now a white-level Gu Master, but the Iron Skin Gu has evolved to the Bronze Level, so I'll be promoted to a Bronze Gu Master, just around the corner!"

Shen Lian clenched his fists excitedly.

I continued to bury my head in research, but less than half an hour later, a strong feeling of hunger hit.

"Well, the vitality should be extracted from food. Shen Lian rubbed his stomach and called out the door.

"Cuilan. ”

"Lian Gongzi, the slave is here. ”

"I'm hungry, get me something to eat. ”

A moment later, Cuilan brought a whole roast chicken and a large bowl of beef soup.

Shen Lian feasted on it, and actually ate the roast chicken and beef soup, and then felt a little full.

"Damn, the amount of food has increased so much. Shen Lian immediately adjusted his diet according to his own situation, eating four meals a day, and adding meat to meet the progress of the Iron Skin Gu in refining vitality.

It is said that it is not true that the poor are rich and martial, the consumption is so large, and if you don't have money, you really don't want to practice martial arts, let alone embark on the road of Gu Master!
