Ordinary cultivators, who have just entered the Jindan stage, will only occupy one-tenth of the dantian, just a very small round bead. Only when the cultivation is promoted to the peak of the Jindan period, will the Jindan occupy five or six tenths of the dantian.

Some gifted cultivators, when they first enter the Jindan stage, the Jindan will occupy two-tenths of the dantian. At the peak of the Jindan period, Jindan occupied six or seven tenths of the dantian.

But, what about Zhang Yifeng's Jin Dan? has already occupied four-tenths of the dantian, you know, he has just entered the golden pill period! Isn't that scary? In the future, when you grow to the peak, isn't it a dantian, that is, a golden pill?

When the time comes, he is typical of being tired and immortal, and his aura does not know how to dry up at all.

Subsequently, Zhang Yifeng smiled, the bigger Jin Dan, the greater the potential.

Unexpectedly, the physique in this life was even better than he imagined. Is this the reason why the Wisdom Tree settled in Zhihai? Or is it the reason why his body has undergone so many transformations.

No matter what the reason is, Zhang Yifeng at this moment feels that he has inexhaustible strength, and even his knowledge of the sea has expanded a lot.

This is the Jindan period.

After entering the golden pill period, all kinds of mysterious spells and magical powers are qualified to be cast, and the golden pill in the body is enough to provide a huge amount of spiritual energy as support.

Although the time to enter the Jindan period is longer than Zhang Yifeng imagined, it is also within the acceptable range.

Next, it's time to go deeper into the Shadow Cultivation Technique.

The Shadow Cultivation Technique is a very magical secret art. Because shadows have no fixed shape, they cannot be touched. This is the most magical trickery in the Lingyue Continent, and there is no one.

However, even if ordinary people obtain this secret technique, they will not be able to learn it.

The Shadow Cultivation Technique is only suitable for cultivators with strong spirits to learn. The stronger the spiritual power, the more handy the shadow cultivation technique becomes.

This in-depth cultivation has been seven days in the past.

On this day, the red candle knocked on Zhang Yifeng's door, and it was time to send the antidote in advance. Zhang Yifeng's antidote, every time he gets it, he will be asked to leave by the five elders. After all, the five elders needed the detoxification pill more than him.

The reason why the red candle sends the antidote is because Su Zhirou has to go to the Black Tower every day. It was a day's time, and no one knew what Su Zhirou was doing.

Zhang Yifeng plans to use secret techniques tonight to explore the Black Tower.

Soon, night fell.

Zhang Yifeng sat cross-legged on the bed, and the shadow under him suddenly fluctuated.

Then the shadow turned into a black line, and along the corner of the wall, Man Yan went out.

The black shadow, although silent, has a fatal flaw, that is, colored, colored nature has traces to follow!

If someone keeps releasing their divine consciousness and then catches the movement of the shadow, they will naturally discover this secret art.

However, Zhang Yifeng is naturally prepared. This is also the reason why he has to wait for the Jindan period before he dares to investigate.

Because of the cultivation of the Jindan period, he can let his own shadow merge into the shadow of any object.

At this time, his shadow followed the shadow of the fence in the courtyard, all the way, silently, and there was no trace to be inquired about.

Tonight, although the moonlight is not very bright, the shadows of all things are still clearly visible.

Since there is Zhang Yifeng's divine sense on the shadow, the shadow is equivalent to his eyes, and using the shadow cultivation technique to probe the environment is definitely much more hidden than the divine sense probe.

Divine sense probing has a fatal drawback, and when you meet someone who is equally strong in spirit, you will definitely be discovered by the other party.

Tuoba Fengyu is an example, every time Tuoba Fengyu conducts divine sense exploration, it can be easily detected by Zhang Yifeng.

Zhang Yifeng's shadow, mixed in the shadow of all things, keeps moving forward without life.

Suddenly, the shadow turned a corner and went to the eaves of Tuoba Fengyu.

When the moonlight was in the sky, there were shadows under the entire eaves, Zhang Yifeng's shadow was naturally invisible, and the next moment, Zhang Yifeng's shadow penetrated into the crack in the door and went to Tuoba Fengyu's room.

For the sake of safety, Zhang Yifeng plans to test the knife with Tuoba Fengyu, and the cultivation of Tuoba Fengyu should be in the Jindan period, if Tuoba Fengyu can't detect the shadow, it means that it is feasible to use the shadow to investigate.

Time passed, and soon half an hour passed.

In the past half hour, Zhang Yifeng's shadow Tuoba Fengyu scurried around the room, but Tuoba Fengyu did not notice anything unusual.

Half an hour later, Zhang Yifeng's shadow was gone. Tuoba Fengyu was still unaware.

Soon, Zhang Yifeng's shadow entered the range of the Black Tower.

At this moment, Zhang Yifeng's face turned slightly pale. The shadow cultivation technique is indeed very consuming of divine sense, and the farther away the distance, the greater the demand and consumption of divine consciousness, after taking a Divine Pill, Zhang Yifeng continued to control the shadow to move forward.

Soon, the shadow went to the bottom of the Black Tower, hiding in the shadow of the Black Tower.

Subsequently, Zhang Yifeng followed the gap and entered the Black Tower.

The Black Tower, the most mysterious place of the Tuoba family, is not one of them. Zhang Yifeng chose to explore the Black Tower for the first time because he felt that it was very mysterious.

But entering the roar of the Black Tower, Zhang Yifeng frowned. He "saw" clearly, all the urns and spiritual tablets in the black tower were placed.

Starting from the middle layer, without exception, it is all spiritual positions.

Soon, Zhang Yifeng arrived at the top floor of the Black Tower.

To Zhang Yifeng's great surprise, there was actually a figure on the top floor.

The figure sat cross-legged on a futon, eyes closed, hands slightly folded.

This person is none other than Su Zhirou. It was already dark, but Su Zhirou didn't go back.

In front of Su Zhirou, that is, in the middle of the entire top floor, there was a black wooden coffin.

I don't know why, Zhang Yifeng suddenly found that Su Zhirou's breath at this moment was somewhat similar to the breath in the coffin.

Zhang Yifeng knew that Su Zhirou was often absent from the courtyard these days, could she stay here every day in front of a coffin and pray sincerely?

So, whose coffin is this? Who is the person buried in the coffin?

Zhang Yi was bold, and his shadow bypassed Su Zhirou and quietly approached the coffin.

The closer he got to the coffin, the more Zhang Yifeng could sense a cold force, which came from outside and converged towards the coffin.

Zhang Yifeng was taken aback, this is the power of the stars and the moon.

This entire Black Tower seems to have a mysterious formation that can absorb and gather the power of the sun, moon and stars. And these forces were absorbed by the coffin. Who is buried in the coffin?

Without hesitation, Zhang Yifeng's shadow climbed onto the black wooden coffin, and then entered the coffin along the gap in the coffin.

In the coffin, it was pitch black, but as soon as Zhang Yifeng entered, an extremely terrifying scene happened.

A pair of eyes suddenly opened, and these eyes released a dark green light, although this light was not strong, but it reflected a pale old face!

This face is naturally the face of the ancestors of the Tuoba family, and these eyes are naturally the eyes of the ancestors of the Tuoba family!

His eyes suddenly widened, as if he had been resurrected from death.
