The old man's spirits became weaker and weaker, and most of the time, he slept on that chaise longue and ate less and less.

Seeing the old man getting weaker and weaker day by day, Shen Yun was very sad in his heart, and he had no choice but to spend some time with him every day.

Although the weather was very hot, Shen Yun could barely see him sweating and wearing thick clothes.

Shen Yun rarely asked him for advice now, trying not to disturb him. The old man doesn't have much energy to teach now, but occasionally he still pushes his spirits and asks about the current study status of his disciples.

This moved Shen Yun's heart, and he was even more reluctant to let the old man bother.

Time passes day by day.

After returning to Sangshan, Shen Yun spent a lot of his free time every day almost on the study of formations and prohibitions.

After carefully studying the formation theory, I found that the formations recorded in it all have requirements for the number and attributes of spirit stones, and some even need specific treasures - array flags and so on to be arranged.

There are only four spirit stones, looking for them, except for the formation that Shang Ling Feng has seen, nothing else can be arranged at all, and the minimum five element arrays all need one spirit stone with five element attributes.

The Mirage Array is relatively simple, only three spirit stones of any attribute are needed.

Once the arrangement is successful, you can conjure up a piece of scenery, of course, you can only deceive ordinary people, and when your divine sense sweeps away, there is nothing to hide. Some immortal cultivators will set up such a formation in their hermitage, so that they can avoid mortals or beasts from accidentally breaking in, and add a little scenery, which is actually not very practical.

A few days later, in a remote courtyard of Sangshan Summer Resort, Shen Yun stood alone.

The gate of this courtyard is locked. On one side of the yard, there is a rockery pool that occupies a small half-space, and the sun is shining, and a few swimming fish occasionally poke out their small mouths and blow bubbles.

If it weren't for the constant chirping of small insects everywhere, it would be an elegant place.

At this moment, Shen Yun had a serious face, and threw a spirit stone in his hand, and then threw another one, another one, and three spirit stones in a row.

Shen Yun's expression moved, and his eyes showed surprise.

With a "hum" sound, the spiritual power in the three spirit stones instantly flowed, forming a hemispherical shield with a radius of several zhang, flashing colorful colors in the sun.

"It's done?" was overjoyed in his heart, and according to what the jade slip said, he invaded his divine consciousness and portrayed a memory of the scene.

In an instant, a wave came, and a flower appeared in front of me, and I saw a few huge rocks in the center of the courtyard out of thin air, and a few clusters of low shrubs dotted with them.

The sun shines on the boulders, and the shadows fall on the pool, which is very realistic.

A gentle breeze blew, and the branches and leaves of the bushes swayed endlessly, as if they were made in nature.

Shen Yun's eyes flashed red, and the scene in front of him instantly faded, leaving only a thin layer of water curtain light wall, which was naturally the true appearance of the formation.

"Hey, that's kind of interesting. Stretching out his arm and reaching in, a hint of coolness came, and the formation also produced a fluctuation.

With a chuckle, he returned his hand to the spirit stone and withdrew the formation.

Once the formation starts to operate, it will consume the spiritual energy in the spirit stone, even if it is consumed very slowly, but it is a waste after all.

The formation recorded in the jade slip is the most eye-catching called the "Spirit Gathering Array". The effect is to gather the nearby spiritual energy into the range of the formation, and the cultivation effect in the formation is better, but it is a pity that it takes eight spirit stones to arrange.

"Wait until the next time I see Shi Qiulan and see if I can borrow a few spirit stones......" Shen Yun smiled lightly with a look of anticipation.

In the next few days, Shen Yun secretly flew into this courtyard every day, familiarizing himself with the Mirage Array, and did not stop until he could arrange it at hand.

The other formations could not be learned for the time being, so they turned to practice prohibition.

There are a total of eight prohibitions recorded in the jade slip, the front is three attack prohibitions and three defensive prohibitions, each prohibition is a five-style technique, it seems that it should not be difficult, and the last two techniques are numerous, so I didn't pay attention to it for the time being.

It took three days for Shen Yun to successfully cast an attack ban.

The attack prohibition is the size of a copper coin, in the shape of a five-pointed star-shaped magic seal, pale red, slightly shining, floating on the fingertips.

After the ban is formed, it can't be held for a long time, so it can only be played out as soon as possible. Once unleashed, it attacks in a straight line and cannot be steered like spells.

The biggest problem is that the power of the ban is too bad.

The conclusion is that it is much slower to cast than the Wind Blade, and the power is far less than that of the Wind Blade.

Shen Yun was strange, to say that the ban had no effect? Then why did the seniors spend time studying it? In the final analysis, he still had too little knowledge of the ban, and he vaguely felt that the ban should have a greater effect.

After all, without the guidance of the master, I couldn't think of why, so I simply didn't think about it and just concentrated on practicing.

The difficulty of the prohibition lies in the coordination of the technique with the mana and the divine sense, and the rhythm must be consistent and balanced.

In addition, unlike spells, the ban consumes very little mana, but it will consume a large amount of divine consciousness, just such a simple attack ban, after only four times, the divine sense is insufficient, and the headache is like a crack.

So I had to stop practicing and meditate to recover.

The good thing is that the total amount of divine consciousness will increase slightly.

After learning the three attack prohibitions, Shen Yun realized for a moment that these prohibitions belonged to the same forbidden deformation body, and there were only a slight difference in the technique and mana.

So, I turned to practice defensive prohibitions, and the three defensive prohibitions in the classics are also five-style techniques.

For a few days, Shen Yun stayed in the study to practice when he had nothing to do.

This morning, there were several thunderstorms, followed by heavy rain.

The sound of the rain was endless, and countless streams instantly gathered on the ground, jubilantly heading straight down the mountain.

For the sound of the outside world, Shen Yun was not disturbed at all, and pinched the strange seal with an expressionless face. Suddenly, an angular, sphere-like magic seal appeared on his fingertips, slightly emitting a faint and colorful light.

Shen Yun looked around and saw that the celadon teacup on the desk was steaming, so he threw the ban into the cup.

With a "bang", the prohibition pounced on the teacup, instantly forming a shield with a dim light and clinging to the cup, which was a bit like a spiritual shield.

The shroud was nearly transparent, and the light faded away.

Strangely, the tea was isolated, and the shield wrapped tightly around the teacup as if it had a film on it.

Shen Yun looked curious, poured out the tea first, and put it on the table to look at it carefully. He stretched out his fingers and pinched them, feeling like touching a smooth jade.

Suddenly, he chanted a word, pinched the trick with one hand, and then with a flash of blue light, a wind blade appeared in his hand, and with a wave of his hand, he slashed the wind blade towards the teacup.

With a "click", the film of the shield shattered inch by inch like a blister and disappeared, and even the teacup inside was split in half with a "bang".

Shen Yun frowned, shook his head and sighed lightly, this defense power is too unsatisfactory.

"Could it be that because this is a basic prohibition, the number of hands is small, and the power is not strong?"

There are two great prohibitions recorded at the back of the formation codex. One is called breaking the forbidden formation, and the function is to break through other formations, and directly open up a passage for monks to pass through in other formations, which is enough to have 7749 style tricks.

According to the current Shen Yun attack ban more than four times, he can only play more than twenty tricks, and his divine sense will be exhausted, so it is naturally not enough to practice breaking the formation ban now.

And the last void-breaking trick is even more incredible, the dense hundreds of tricks are not at all a ban that can be considered for practice now. What is the use of breaking the void, I didn't mention it, I only recorded a name.

The complex prohibitions could not be learned, so they had to continue to practice defensive prohibitions.

After another period of time, gradually the three defensive bans were completely mastered, and with continuous testing, some characteristics of the defensive forbidden were finally discovered.

The first is the persistence of the prohibition shield.

Once the ban is thrown, after the target is protected, there will be no more consumption, and it will last for a long time, and Shen Yun even faintly feels that it may exist for many years;

The second is the superposition of defensive prohibitions.

However, this has a disadvantage, that is, it cannot be stacked with the same prohibition.

If the first ban is applied to a teacup, and then a second ban is cast, the previous shield will be replaced by a new one. Only by using the second defensive ban can you add another layer of protection to it.

In other words, unless Shen Yun learns more defensive bans, he can only stack a maximum of triple bans on one target;

The third is that the power of the defense ban is affected by the target.

To put it simply, it is necessary to look at the size of the target of protection, which has a poor effect on large targets and good effect on small targets.

For example, the triple prohibition is superimposed on the big stone, and the wind blade technique cuts through it, and it is broken in an instant. But with three protections on the teacup, the Wind Blade Technique was completely blocked.

These discoveries made Shen Yun overjoyed, so he increased the practice and experiment of various prohibitions, but unfortunately, once the attack ban was formed, it had to be fought out, and it could not be superimposed like a defensive ban.

"In the future, if you come into contact with more defensive prohibitions, and then superimpose protection on your body, will it be far more powerful than the spiritual shield?" Shen Yun's eyes were shining, full of anticipation.
