Yu Guihai carefully searched for the crux of the problem and found that the core runes of the Yin Qi Shield were much more complex than those of the Yin Determination Technique, and the lines were more refined, which caused its structure to be quite fragile. Once the input spiritual energy was slightly too large, it would cause it.

Disintegrate.

When he was just starting to learn, he could not input too much spiritual energy, he could only input slowly to stabilize.

After finding the crux of the matter, Yu Guihai casts the spell again, and his spiritual control power reaches perfection. This time he carefully controls it. After about a minute, he finally succeeds.

He thought, and a gray illusion shield of one meter was blocking his body.

The shield is illusory and transparent, with a circle of mysterious and peculiar runes on the edges.

"I don't know how defensive the shield is?"

Yu Guihai thought for a moment, then punched out violently, bombarding the middle of the shield.

With a loud bang, the powerful fist force exploded, forming a strong impact and burst out.

The surface of the illusory shield was just rippling, and it quickly returned to normal without being broken at all.

"The defense of physical attacks is very strong!"

He used a full-strength attack that contained almost no internal energy, which basically did not pose a substantial threat to the shield.

"Then let me see how I defend myself against internal energy."

Yu Guihai thought, and a blue internal energy emerged from his fist. A bursting tiger roar suddenly sounded, and a huge tiger head formed outside his fist, slamming into the shield.

Boom ~

With a loud bang, the blue internal energy and gray yin energy burst out from the contact point, and countless blue and gray intertwined breaths burst out everywhere.

A huge turmoil appeared on the shield in an instant. Along with ripples, a sag appeared from the fist. After supporting it for a while, the shield collapsed into countless gray-black yin energy.

"The strongest can support the power of the later stages of the ordinary internal Qi realm."

Yu Guihai withdrew his fist and thoughtfully.

He worked his best in this circle and used the strongest move of the Tiger Roar Fist, and his attack power was even comparable to that of an ordinary warrior's inner Qi realm.

In this way, you can barely break the shield. It can be seen that the Yin Qi Shield has a very good defense.

You know, this is only his first actual combat success, and this magic has not even been introduced. If he practices it to perfection, its power will definitely reach the level of Tongmai Realm.

"Very good! Let me see if I can get started with my cultivation today. If I can, I will save a little upgrade."

Yu Guihai was thinking in his mind and visualized the core runes of the Yin Qi Shield again.

One minute later, a Yin Qi shield was deployed again.

This spell casting time is really touching, and there is no chance to cast spells in actual combat. If Yu Guihai hadn't known that this spell could be instantly fired after it was perfect, he would probably not have the motivation to learn.

"This time, try your defense against sword techniques!"

Yu Guihai reached out and pulled out the long sword of the black blade. Under the infusion of internal energy, a blade light flashed like a blue tide. Suddenly, a bright moon rose in the sky above the blue tide, and then,

Yu Guihai suddenly bounced up and rushed towards the top.

The Yin Qi shield moved to his feet instantly with his thoughts.

Boom ~

With a cracking sound of the sky and the earth, the entire cavernous ground shattered, and countless gravel shot out, like a powerful crossbow, shooting holes into the surrounding stone walls.

The gravel shot towards Yu Guihai was just blocked by the Yin Qi Shield, and only ripples oscillated on the shield surface, which could not hurt Yu Guihai behind the shield at all.

But immediately after the gravel, a huge black shadow as thick as a bucket hit hard, hitting heavily on the Yin Qi shield.

The Yin Qi Shield supports a breath and then dissipates and disappears.

But with this delay, Yu Guihai had already rushed up the cliff like a monkey. The huge black shadow followed closely behind and slashed past his face.

It was not until this time that the long sword in Yu Guihai's hand fell down.

With this sword, he had accumulated momentum for a long time, and his energy surged out from the whole body. He even mobilized some of the Xuanyin spiritual energy, forming a phantom of several meters of blue and black sword energy, slashing through the black shadow.

Swish ~

With a light sound, the black shadow was cut off with a knife.

At the same time, with a click, Yu Guihai felt a lighter in his hand, and the sharp weapon-level mysterious blade was broken inch by inch, leaving only the hilt in his hand!

ヾ(≧o≦)ッAo

A dull roar came from a very far below the ground, and the ground was shaking.

Half of the black shadow whipped and shrank into the valley, retreated into the pool, disappeared, and the remaining half fell on the cliff, constantly whipping and squirming.

Yu Guihai looked carefully and found that it was half a piece of tentacle as thick as a bucket. The tentacle was pitch black and smooth, with a large cross-shaped mouth at the tip opening and closing, revealing the huge spiral-like dense teeth inside.

Silent ~

As the tentacles struggled, the tentacles kept releasing waves of extremely cold black smoke, and their body size continued to shrink, and soon turned into a soft black skin and fell to the ground.

The cold and cold air kept drilling into the body, and even the remaining internal energy could not completely resist. Yu Guihai couldn't help but chill and hurriedly mobilized the remaining Xuanyin spiritual energy to resist Qihan.

However, the Xuanyin spiritual energy was also quickly consumed, and it seemed that it would not last much time.

"What a powerful yin energy!"

Yu Guihai's expression changed slightly. He hurriedly stepped forward and grabbed the black skin on the ground and quickly retreated out of the area covered by the black fog.

As far away, Yu Guihai looked at the thick black fog with lingering fear. If he retreated a little slower, his spiritual energy would be consumed.

Then he felt regretful that such powerful Yin Qi had no cultivation array to absorb it. He could not even be sure whether the magic array depicted by the white lantern paper could carry such powerful Yin Qi.

Fortunately, as long as the sun rises, the yin energy will dissipate quickly, otherwise some powerful ghosts may be produced after a long time of existence.

"Forget it, let the yin energy dissipate by itself!"

Yu Guihai came back to his senses and did not dare to stay for a long time, so he ran towards the distance.

He stopped in a hidden valley, meditated for a while, and then took out the black skin left of the tentacle and looked carefully.

The black skin is wrinkled, and the black background has a strange gray pattern. It seems to contain a powerful yin and cold atmosphere, like a mist and a sea, looming, and it is elusive.

This thing is definitely not an ordinary ghost material!

Yu Guihai tried it and found that the black skin was extremely tough and there seemed to be some hard objects inside.

He turned on the black skin and found that there were several sharp teeth hanging inside.

He broke off his teeth, and there were seven in total. These teeth were more than an inch long and were pale and strong, and obviously also a good material.

Yu Guihai thought for a moment, bit his finger, and used a tooth to draw a cultivation array on the black skin with blood.

However, after the blood is drawn, it is like it is drawn on a mirror, and it cannot be attached at all. It is slightly raised and the blood drops flow down immediately, and it cannot be drawn at all.

Yu Guihai pondered for a moment and then put away his black skin and teeth.
