As soon as black fog appeared, it enveloped the entire cave.

Immediately, five men and five women, ten and half-fifth, and the naked and beautiful men and women were looming in the fog.

These ten people are as erratic as smoke, the handsome man is and the beautiful woman is. There is no trace of anger in their eyes, but only lust and strong evil spirits.

As soon as they appeared, ten people swayed their bodies, with a very charming and seductive posture.

Ge Tianchuan Yu Guang swept over the five naked women, and his heart immediately started to thump.

Even though he was an evil cultivator, he felt his mouth and tongue dry at this moment.

"snort!"

It was not until the man in the gray robe let out a muffled groan that he woke up like a dream, came back to his senses, and asked the other party.

"Lord... is this?"

"This is given by the young master, five pairs of Nine Yin evil demons. It is made by using the ghosts of the foundation-building monks who love to practice dual cultivation, and is forged with the Nine Nether Demon Fire to refine them for a thousand days."

"Now these five pairs of evil demons specialize in capturing the true energy, which can make people lose their bones and destroy them silently!"

"This time I will lend you these five pairs of evil demons for a while. If you fail again, I will take your life in person!"

The man in the gray robe stood calmly, with an understatement as if he was explaining the facts.

When Ge Tianchuan heard this, his back felt cold.

Only then did I realize that most of the true energy in my body had disappeared silently after the loss of consciousness.

If the other party hadn't reminded him in time, I'm afraid he wouldn't know how he died.

"Don't worry, Lord, I am willing to guarantee my life this time!"

Ge Tianchuan crawled on the ground, both surprised and happy.

What was shocked was that the Lord's strength was so strong and his methods were so strange that he was far beyond his imagination.

What I am happy about is that with such evil demons, it is no longer difficult for him to take Su Shier!

At this moment, Ge Tianchuan's confidence surged again.

Then, whispers sounded in the cave, and the man in the gray robe did not show his voice, and passed on all the methods of controlling evil spirits.

Push the pine cliff.

Seeing Shen Miaoyin flying away, Su Shier used the formation technique again, causing the white mist to fill the mountain again.

After doing this, he turned around and returned to the secret room again.

Sitting cross-legged on the cushion, Su Shier immediately took out the Heaven and Earth Furnace and placed all the spirit stones in his body in it.

Using medium-grade spirit stones to practice will have better results than low-grade spirit stones. Su Shier will naturally not miss this opportunity.

It will take some time to temper the spirit stones. Su Shier was not in a hurry to practice. He took out the storage bags of the five men in black and the boy Ge Tianchuan to check and organize them.

Except for that boy, the other five people had many treasures.

There are one top-quality magic weapons, one middle-grade and top-grade magic weapons, and there are more than twenty pieces in total.

As for elixirs, spiritual plants, and spiritual materials, there are also many.

After Su Shier sorted out the things and sorted them out, he opened the furnace to refine the alchemy and used all the spiritual plants he could use.

In the world of immortal cultivation, many monks will open up spiritual fields in the cave and plant and cultivate rare spiritual plants. In this way, they will obtain spiritual plants repeatedly and continue to grow.

Su Shier did not understand this path, and did not intend to stay in one place for a long time, so he naturally would not waste time on this matter.

Until one month later, nearly 4,000 spirit stones in the Heaven and Earth Furnace turned into thirty-nine medium-grade spirit stones, and the remaining more than 90 low-grade spirit stones were less than a hundred, without any change.

"It seems... the requirements for the synthesis of spirit stones in this Heaven and Earth Furnace are really strict. One hundred spirit stones are not enough!"

"It's good that this is the case. These remaining low-grade spirit stones can also be kept for emergencies."

"Next, it's time to go into seclusion and practice!"

After putting away the spirit stones, Su Shier threw the non-highest spiritual pills he had collected or refined into the Heaven and Earth Furnace.

He allowed the Heaven and Earth Furnace to temper it, but he raised his head and swallowed a Qingyuan Pill, held a medium-grade spirit stone in each hand, and began to practice.

The elixir turned into a clear stream to soak the lungs, and quickly spread throughout the limbs and bones as the true energy in the body rotated.

At the same time, a powerful force surged in the palms of Su Shier's hands.

And under him, the cushion gathered the spiritual energy of heaven and earth and rushed into his body.

The four strong currents merged into the meridians, and the powerful energy immediately made Su Shier feel that the meridians in his body were about to swell and break.

To endure so much energy at the same time, it is indeed a serious overload for his meridians.

But Su Shier knew in his heart that if he did not do this, with his spiritual root qualifications, it would be even more difficult to quickly improve his cultivation.

With his teeth tightly clenched, Su Shier closed his eyes tightly, and sweat kept oozing from his forehead, but he didn't care at all.

As energy surges through the meridians, every circle of heaven, there are a trace of pure true energy that flows into Su Shier Qihai Dantian and turns into liquid droplets.

As the true energy continues to flow in, the liquid droplets gathering in the dantian are also expanding.

From one punch to the size of a bowl, to the size of a basin!

Cultivation is a hard skill, and requires patience to wear water and stones.

And Su Shier never lacks patience.

Time just flows bit by bit.

In a blink of an eye, eight years passed.

In the secret room, Su Shier was still constantly practicing.

On the ground in front of him, there were scattered spirit stone debris and empty elixir and porcelain bottles scattered all over the ground.

Compared to eight years ago, Su Shier was obviously much more calm when he refined the spiritual energy of heaven and earth with such high intensity.

He looked calm and there was no more pain on his face.

It's a habit, and it's also because of the improvement of strength.

The four streams merge into his meridians, like thousands of horses galloping.

And the true energy pouring into Su Shier's dantian also turned into a small pond.

Suddenly, the pond surging violently, and the powerful Haoyuan suddenly surged out of Su Shier's body, filling the entire secret room.

Su Shier, who was dedicated to practicing, was completely unaware of it.

“Huhhhh…”

Immediately afterwards, the true energy turned into a gust of wind in the secret room, like hundreds of bellows whistling.

The movement lasted for a whole day and a night.

A day later, the last two medium-grade spirit stones in Su Shier's hand turned into flying ashes.

In his dantian, the true essence condensation suddenly rotated and turned into a spiral flow.

In an instant, the true energy flowing outside the body suddenly contracted and returned to the Qihai Dantian.

"Click!"

It seemed as if something was shattering in the dantian.

The originally large space of the Dantian has expanded three points.

"call……"

The next second, Su Shier suddenly opened his eyes, and two rays of light burst out from his eyes.

At this moment, his aura surging around him, whether it is the strength of his aura or his cultivation level, it has increased several times more than eight years ago.

"Finally the middle stage of foundation building!"

"I really didn't expect... I spent so much resources to cultivate to the middle stage of foundation building!"

"However, the medium-grade spirit stone is really powerful, and it has allowed me to break through to the middle stage of foundation building in just eight years. In comparison, what is it to consume more resources?!"

Taking a deep breath, Su Shier quickly restrained his breath around his body and calmed down the true energy rushing in his body.

Compared to consuming resources, he cares more about saving time.

If you still use the lower-grade spirit stone, it will probably take at least twenty years to break through to the mid-stage.
Chapter completed!
