And what kind of water pump is suitable for what kind of water pipe has also become a top priority.

In the pursuit of efficiency, the use of high-power pumps will lead to the bursting of water pipes, and the use of low-efficiency pumps is a waste of high-quality water pipes.

However, the level of the practice cheats is often not high, and among the four levels of "heaven", "earth", "xuan" and "yellow" of the exercises, the yellow rank is the most common exercise.

The Xuan-level exercises are already wind-haired water chestnuts, while the earth-level and celestial realm exercises have almost disappeared and no one has ever seen them.

Although this "Yellow Rank" exercise is not very good, it is also relatively good, and those who have the Xuan Rank Exercise have basically already started a sect and passed it on.

There are two parts to the Giant Spirit Law, one is to teach the occultists how to guide the mystical qi in nature for their own use, and this part occupies four-fifths of the book.

The other is to teach the mysticists how to guide the mystical qi in the utensils for their own use, and this part only occupies one-fifth of the space.

The reason is very simple, how can there be so many utensils that store Xuan Qi!

Even if there were, they were all terrifyingly expensive Xuandan, which was really something that the vast majority of ordinary Xuanists in the world could not afford to consume.

Even if some mysteries come to the secular world to act as bodyguards for the rich, they are restricted by the mystical guild everywhere, and they have no skills to display at all.

In order to maintain the balance of the secular world, the Xuanzhi Guild also levies a particularly high offering for the mystics to come to the secular world to use the mystical power to make money, which makes ordinary mysteries complain.

In addition, it is not very useful for them to ask for so much money, and the money they earn by spending time and energy is far less beneficial than improving their strength.

Some people may say that after making money, you can buy pills to improve your strength, but the cost of pills has exceeded imagination, and the mysteries don't dare to imagine how they can make enough money to use pills to improve their strength.

Therefore, today's exercises often focus on guiding the cultivation of the Xuan Qi in nature, and the method of guiding the cultivation of the Xuan Qi in the utensils is just a passing stroke.

After Chi Shen learned about this situation, he directly turned the "Giant Spirit Law" to the second part, for no other reason, he has a chaotic treasure and is willful.

If, according to Bao'er, the Chaos Arcana is connected to the Chaos World, as long as the Chaos World is not destroyed, then it has endless mystical power to absorb.

Chi Shen carefully read the cultivation method behind it, and quickly memorized the mantra.

Although Chi Injury's memory is good, this is not the reason why he can memorize it so quickly.

It's because when he was reciting this mantra, he felt an inexplicable sense of familiarity!!

I even found many mistakes in the mantra and corrected them by the way.

It's like we're reciting a text we've memorized, and we only need a few glances to recall a lot of it.

But what Chi Hurt can confirm is that he has never seen this thing.

After reciting the mantra, Chi Hurt sat on the bed in a meditative posture in accordance with the requirements in the "Giant Spirit Law", and the position of the Chaos Arcana was not required, so Chi Hurt did not choose to take it off.

As the last character of the mantra was read out by Chi Injury, the world around him suddenly became very clear, and Chi Injury had never felt that his connection with the world around him could be so close, he could clearly see every corner of the room, even the leg of a mosquito, as if he could reach out and grab it.

The sense of hearing has also become extremely sensitive, and the vision is blocked by the wall, but the sense of hearing can be easily probed out by the delayed injury.

When he was 10 meters away, he heard the sound of rats gnawing peanuts in the burrow, and when he was 20 meters away, he suddenly heard a strange sound.

"Hmm...... Hmmm......"

"Hard, ah. ”

Chi Hurt looked embarrassed, and then remembered that there was a little couple living not far from their home, in line with the principle of not seeing and listening to indecent things, Chi Hurt continued to expand the range of hearing.

50 meters.

This is the longest distance of the delay injury test, and these 50 meters are not the 50 meters of our normal hearing, but any wind and grass sound within these 50 meters will be captured by the delay injury.

Of course, it also includes the little couple just now......

While testing his sight and hearing, he felt a wave of Xuan power shoot from the Chaos Arcana towards his body.

One, two, five, ten, twenty...... Thirty ......

Fifty courses!

The number of Xuan Li waves was fixed at fifty.

Chi Wound's body is like a bottomless pit, absorbing the energy of the Chaos Treasure.

Chi Hurt felt that his eyes were dark, and his surroundings turned into a gray world.

"! I just got out here!"

That's right, Chi Wound has returned to the space of the Chaos Arcana.

But this time, Chi Sadness didn't panic, because he knew the way to get out.

He first called for a long time, but he didn't get any response, thinking that he hadn't woken up yet.

"It's really strange, when Bao'er wakes up, I must ask her to understand. ”

When he entered the Chaos Arcana, he was still sitting on the ground in a meditative position, and this time he did not explore the world around him again, but continued the process just now.

At this time, he only felt that there were fifty snakes scurrying around in his body.

He knew that it was his fifty Xuan veins that were continuously absorbing the Xuan Qi of the chaotic space.

Although Xuan Li was able to absorb it into his body by using the exercises, the Xuan Li wave was like a headless fly scurrying around his body with a delay in injury.

Chi Qi must be tamed immediately, otherwise as the Xuan Qi becomes more and more, he will definitely not be able to hold on.

Although he was aware of this problem, his speed of taming Xuan Qi still couldn't keep up with the speed at which his fifty Xuan veins absorbed Xuan Qi.

Late Injury is now like a balloon that is gradually inflating, and it has the potential to explode every minute and every second.

There are more and more Xuan Qi.

"Bang"

A crack appeared in the wounded clothes.

Two...

Three of a kind...

Until all the clothes are reduced to shreds.

The speed at which Xuan Qi flowed through the body became faster and faster, faster and faster, and it seemed that it was about to get out of the control of Chi Qi.

Chi Wound finally couldn't help it, and a scarlet blood sword erupted from Chi Wound.

At this time, the delay was tense, and even the blood stains on the corners of his mouth had no time to wipe off.

He gritted his teeth and creaked, and continued to fight against the Xuan Qi in his body.

Every minute of it, he was suffering immensely.

He felt as if his body was being torn apart.

It seems to be eaten by countless ants.

If someone saw Chi Ji's body at this time, they would definitely be surprised and speechless.

His skin was turning from wheat yellow to scarlet and then to purple.

......

The world passes by in a minute......

Finally!

The first wisp of Xuan Qi was guided into the dantian by Chi Injury.
