Yu Guihai was going to try his own practice first. If he could practice at one level and two levels, wouldn't he be able to save one or two upgrade points.

The core of this spell is a mysterious rune that looks evil and twisted, and the whole thing is very complicated.

When practicing, you must first use your mental power to visualize this rune in your mind.

This step requires relatively strong mental strength and mental control.

For ordinary practitioners who have just entered the qi training period, this is very difficult because their spirit is not strong enough and they need to be strengthened a little bit. Only when their mental strength is sufficient can they be able to visualize.

But Yu Guihai felt that it might be easier for him, because his spirit had undergone a sudden increase in sublimation and was relatively powerful.

He closed his eyes and concentrated, and after a little experiment, a twisted mysterious rune was outlined in his consciousness. The process was unexpectedly easy, and he did not feel any difficulty at all!

"So simple?"

Yu Guihai was surprised in his heart, and then he felt excited again. As a result, his spirit surged, and the runes instantly collapsed.

He hurriedly adjusted his breath and concentration to calm down his excitement, and then visualized the runes again.

After visualizing the runes for the second time, he suddenly felt that his spirit had become slightly weaker, as if something had been consumed.

This is the mental energy consumed.

He made a judgment and concluded that visualizing the spell runes of the Ding Yin Technique once consumes very little mental energy. Visualizing it dozens of times in a row is not a problem.

Yu Guihai looked at the invisible interface and found that the mental attributes had not changed.

This is because the mental attributes on the interface only represent the upper limit level of one's own spirit. It is just a display of the limit value, so it does not decrease with the consumption of mental power.

Visualizing the runes is only the first step.

The next step for this little spell is to pour the spiritual energy in the body into the runes, filling them up, and then the spell can be cast naturally. With just a thought, it can be fired at the target.

This step tests the control of spiritual energy, which will also not hinder Yu Guihai.

After each upgrade, he can perfectly control the increased spiritual energy in his body.

With a thought, the Xuanyin spiritual energy in the body is continuously input into the runes.

It took more than ten breaths for Yu Guihai to input 90% of the spiritual energy in his body, and then the runes were filled.

At this time, he finally understood why he had to reach the third level of Qi Refining Stage before he could learn this little spell.

It’s entirely because the spiritual energy from the first and second levels of Qi training is simply not enough to be released once!

In addition to being too expensive, the casting speed of this spell is also too slow!

During the battle, I am afraid that I will be killed before it is released. It has no actual combat value at all.

It's no wonder that monks during the Qi training period have no advantage over warriors.

The spell consumption is high and the casting speed is too slow, which are all flaws.

Yu Guihai sighed, looked around and saw that there was no target for casting spells, then kicked up a piece of gravel and hit a bush in the distance.

Suddenly, a hare jumped up from the grass and ran away into the distance.

With a thought in Yu Guihai's mind, the prepared Yin-fixing technique was immediately sent out.

I saw a black light flashing past like lightning, crossing a long distance and landing on the rabbit in an instant.

Plop~

The hare that had just jumped up stiffened and immediately fell to the ground. In an instant, it was frozen and completely breathless!

After all, it was just an ordinary rabbit, but it was directly frozen to death by the Xuanyin aura contained in the spell!

As for the effect of the spell sealing the energy in the body, it was not shown at all.

"The speed of the spell is extremely fast after it is released!"

Yu Guihai was a little surprised, the black light flew faster than he expected.

He asked himself, if he was unprepared, he would never be able to escape. But he could temporarily activate his inner energy to resist.

This is already very good. As long as the spell is released, it will be difficult for the enemy to avoid it.

Yu Guihai called up the system interface and discovered to his surprise that he had already mastered the Ding Yin technique.

He is determined to continue practicing, but unfortunately the spiritual energy in his body has been exhausted. If he wants to practice, he can only recover it first.

Yu Guihai looked around. The Xuanyin energy here had become even thinner after he had just upgraded and absorbed it. If he wanted to practice and restore the spiritual energy, he would have to find a new place.

Thinking of this, Yu Guihai stood up and left quickly.

At the same time, his powerful five senses were completely released, looking for a place where Xuanyin energy was abundant.

The light-body lifting technique was in full swing, and Yu Guihai was like a fierce tiger in the mountains, leaping up the mountains and jumping into the streams with lightning speed.

The darkness of the night poses no obstacle to him at all. His sight can easily penetrate the darkness and see distant distances clearly. His hearing can capture movements of a hundred meters around him. His mouth and nose can sense all kinds of noise brought by the wind.

A taste.

His direction is to go deep into the mountains.

Nowadays, his position is on the edge, and it is difficult to find a place with strong Yin Qi.

Only by going deeper and reaching those inaccessible areas can we make discoveries.

Of course, he also has a sense of propriety. At most, he will stop at the junction of the edge zone and the depths of the mountains, and will not really go to the dangerous depths of the mountains.

In this kind of borderland, powerful ghosts above the level of resentment usually do not appear. Occasionally, some low-level beasts or ghost-level ghosts appear. They may be extremely dangerous to ordinary people, but they are not enough of a threat to him.

As he went deeper, the forest around him became denser, the surrounding mountains became taller and taller, the valleys became deeper, and the cliffs became steeper.

Suddenly, Yu Guihai's body froze and stopped.

There was a cliff at his feet. It was pitch black under the cliff and he couldn't see the details clearly. However, he could clearly feel the strong Yin Qi gathering below.

Although its richness is not as rich as the Poisonous Miasma Ridge Cold Pond, it is still up to the standards of the Yin Land, and is many times stronger than the previous deep valley.

"Sure enough, you still have to go deep to find the place where the Yin Qi is strong."

Yu Guihai looked under the cliff, the corners of his mouth slightly raised.

However, Yu Guihai did not go down directly. Instead, he found a secluded and clean place on the cliff, sat down and began to meditate.

There are likely to be ghosts entrenched in this underworld, and it would be dangerous to go down there rashly.

It would be better to practice on this cliff and replenish the Xuanyin spiritual energy first.

On the contrary, you can also absorb a lot of yin energy from the cliff below.

Yu Guihai closed his eyes and meditated, and used the Xuanyin Contemplation Method. The illusory figure immediately appeared in his mind and began to release a powerful force of attraction. The surrounding Xuanyin energy was quickly attracted.

Soon, a strong whirlwind formed outside Yu Guihai's body, releasing an even more powerful suction force and began to absorb the rich Yin Qi below the cliff.

Suddenly, he felt a strong Yin Qi rolling in, and they poured into the illusory figures one after another, and then they were transformed into Xuanyin spiritual energy and fed back into his body.

It didn't take long for Yu Guihai to recover less than half of his exhausted Xuanyin spiritual energy.

Seeing Xuanyin's spiritual energy recovering rapidly, Yu Guihai's expression suddenly changed slightly.

When he was practicing to restore his spiritual energy, he was not completely immersed in the practice. Instead, he was paying attention to the situation around him. If any disturbance occurred, he could stop practicing at any time and respond to it.

At this time, under the cliff, there was a strange fluctuation in the underworld!

"Ghost!"

Yu Guihai's heart trembled. He was very familiar with this kind of fluctuation. It was the fluctuation of ghosts.
