Gu Changan didn't remember what happened before he was three years old.

Although from the moment he was born, his soul was reincarnated from the earth world of the 21st century.

However, the brain development of a baby under the age of three is not yet complete. Lacking a mature physiological foundation, he really can't remember what happened to him before he was three years old.

As he gets older, the memories of the prosecutor in his previous life are slowly unsealed, and he matures faster than his peers, and he has long passed the psychological stage of a little child looking for his mother.

As for his own mother in this life?

Because of the bloodline inheritance, Gu Changan has also been curious many times.

But the rationality of his mind made him not have too strong a desire to find his biological mother.

But to be honest, this is another knot buried deep in the bottom after all, at this time, Gu Changan shook his head unconsciously and laughed.

"Maybe the next time I see that cheap daddy, I can ask him ......"

In this way, Gu Changan put this matter behind him and continued to practice wholeheartedly.

After that Pei Yuan Pill slid into his abdomen, it turned into a trace of warm medicinal power, and under his guidance, it circulated along the eight veins of the Qi Sutra.

Gu Changan's body temperature gradually rose, and a hazy mist of sweat evaporated. And his lower dantian also seemed to be lit up with a bright lamp, and an earthy yellow light shone through his internal organs and limbs, penetrating through his skin.

From the outside, his skin is bright and dark. When bright, his skin is like copper, and even his bones occasionally take on a black outline.

This is exactly the sign that a martial artist has cultivated to the third realm, the copper skin and iron bone.

As early as a year ago, Gu Changan passed the two extreme tests of scorching fire and ice water training, and successfully advanced to the copper skin and iron bone realm.

But what he cultivated after all was the left-path evil art of "borrowing heavenly power from Mao Daiyin", which could only allow him to push his martial arts cultivation to the fourth realm-Jian Xin-that is, to the extent that he could just temper his natal Xuan Soldier.

Further up, the road comes to an end.

Therefore, for a long time in the future, his purpose is how to break through the confinement of this fourth realm, and to eliminate as much as possible the backlash effect of "borrowing heavenly power from Mao instead of Yin" to repay debts.

After majoring in the practice of "borrowing heavenly power from Mao instead of Yin", Gu Changan had to repay the "heavenly debt" almost once in the middle of every month.

The way to repay the "natural debt" is to give one's body a variety of tonic ingredients or medicinal materials.

Sometimes you can't change it in one day, and you even have to go for three, five, or even ten days in a row.

This way of repaying debts every month is similar to Gu Changan's previous life, where he regularly repaid a certain bei and a certain white strip every month......

After this night of practice, Gu Changan was full of comfort.

Then he turned over and got out of bed, opened the bottle of the Nine Heavens and Ten Earths Great Tonic Pill from the hand of Kui Gang Guoshi, swallowed one with warm water, and his spirit was more full by three points.

The Nine Heavens and Ten Earth Great Tonic Pill is worthy of being a rare elixir, and just one has paid off Gu Changan's "heavenly debt" this month.

He had carefully counted it before, and there were a total of thirty-six of these Nine Heavens and Ten Earth Great Tonic Pills, which could theoretically pay off three years of "heavenly debt".

As for what will happen later? I'll figure it out later......

And today's task is to go to Ghost Alley to track down the cause of Zhao Sishui's mutation.

After combing through his thoughts, Gu Changan got out of bed and dressed and put on his shoes.

Today, only he and Chen Xuanzong went to the ghost alley, and there was no need to wear the official clothes of bad people, so Gu Changan changed into a plain robe and long clothes.

Pushing the door out, after a night of spring rain, even the air is much fresher, with a hint of the fragrance of flowers and earth.

Chen Xuanzong was already waiting outside his door, with a black robe, a tall figure, a cold side face, and a pen tube standing straight at the foot of the steps.

"Lao Chen, let's go, let's go to Ghost Alley today to see the world."

A master and a servant strode out.

The fat housekeeper Lao Luo happened to be in the courtyard directing the family to sweep the courtyard, and when he saw this master and a servant walking in the wind, he couldn't help but joke from afar: "The eldest prince is dressed so brightly today, but what about the beautiful girl who is going to the house?" ”

The little maids who were taking care of the flowers and plants nearby heard the appearance of the eldest son, and they all blushed with shyness, but they couldn't help but be busy, and secretly looked at the handsome and dashing eldest son with the corner of their eyes, and they couldn't help but feel a little itchy.

Tiandu City has long had rumors of "Four Youths in the Capital", which are not only the sons and daughters of the four noble families, but also the four young men with beautiful appearances.

Our eldest son of the Gu family, although he is more than stepping on four of them with one foot, still has the hard power to protect two and fight for one, right? Let's just say that Xu Gongmao, who ranks first in the "Four Youths of Beijing", is beautiful, but the fly in the ointment is that there is more femininity and less fortitude.

If you take him and Gu Dagongzi side by side, who is better, it's hard to say, right?

"I'm not interested in women."

In the face of Steward Luo's ridicule, Gu Changan's steps were as vigorous as the wind, and his tone of speech was also very indifferent.

When the little maids heard this answer, they were very surprised, and then they couldn't help but hold their hearts and start thinking wildly.

This eldest prince shouldn't be interested in men, right?

Although they are girls, they have also heard a lot of stories about the habit of broken sleeves and the good of Longyang...... Especially in Tongdu Dayi, which has a large population and a prosperous economy like Tiandu City, it can be regarded as floating everywhere......

"I'm not interested in humans either."

In order to avoid ambiguity, Gu Changan, who had gone away, added another sentence from afar. He's going to Ghost Alley today, and he's going to investigate unnatural events and abnormal humans, so there's nothing wrong with that.

But in the courtyard behind him, the fat housekeeper Lao Luo, the housekeeper who swept the floor, and the maids who took care of the flowers and plants were all dumbfounded in an instant.

"The eldest prince is not interested in humans...... Isn't it because youkai are interested? ”

"For example, fox girls, rabbit girls, and cat girls who have been cultivating for hundreds of years?"

"-The taste of the eldest prince is really unique!"

……

Gu Changan came to a morning market in the east of the city and ordered a bowl of spicy soup, which was considered to have been breakfast.

Then I turned into a potholed fish market and entered a gloomy street.

This street is called "Yinquan Street", and the shops along both sides of the street are all doing business for the dead, including shroud shops, coffin shops, coin shops, two leather shop, and even a large Yizhuang in the distance, which specializes in parking the corpses of people who died in the capital.

The atmosphere here is gloomy and quiet, and the bustling scene of people and cars outside is completely different from the bustling scene outside.

Gu Changan and Chen Xuanzong came to an ancient building.

The old building was in a dilapidated state, with red paint mottled and peeling off on the two pillars in front of the door, and tiles falling from the rafters above the eaves, revealing rotten wood that had been eaten by insects and wind and rain. Above the gate hangs a slanted, rickety plaque -

Siyin Building.

The two of them stepped into the threshold of the ancient building.

"Those who enter the ghost alley for the first time must first come to me to drink a bowl of forgetful soup, and then step on the Nai He Bridge in front of them, waiting for the Huangquan guide to come to the ferry.

"People who often go in and out of Ghost Alley also come to me once a month, drink a bowl of forgetful soup, and continue to repeat the previous process. If you don't follow this rule, you will be at your own risk! ”

It was an old woman's voice, hoarse and low, but with a cold and gloomy wind.

Gu Chang'an's eyes slowly adjusted to the darkness here, and only then did he see a tattered wooden table in the center of the hall in front of him, on which were many broken bowls begging for food on the street like beggars.

Next to it was a large iron pot, and there was no firewood underneath, but clusters of miserable green yin fires were burning. The pot was filled with a dark brown soup, which was boiling with a very bitter taste.

The old woman, who was stirring the soup with a wooden spoon, was hunched over, ragged, gray-haired, and wrinkled with the texture of an old tree.

Her name is Granny Siyin.

Seeing that Gu Changan and Chen Xuanzong were indifferent after entering the building, Granny Siyin put down the wooden spoon in her hand, raised her head, looked at the two of them with a pair of old and deep eyes, and let out a few harsh sneers.

"Don't break through the ghost gate, and it's hard to turn back on Huangquan Road. Since you don't dare to go to Ghost Alley, then turn back as soon as possible, and maybe live for a few more years! ”
