233.

When the first crystal droplet in the Tai Chi cyclone fell out, the aura in the entire dantian suddenly changed.

The thin stream composed of liquid droplets began to gather out of the dantian continuously, and then all gathered next to the Taiji cyclone, and finally condensed into a small crystal clear water droplet, which floated quietly on the side of the Taiji cyclone, guarding the Taiji cyclone, just like a small satellite of the Taiji cyclone.

According to the knowledge of cultivation that Cheng Li had known before, he understood that this was what the cultivator called the liquid tire.

In fact, after entering the foundation building period, one of the most important aspects of cultivation is to cultivate more liquid tires.

1 drop of liquid tire can enter the initial stage of foundation building, 3 drops can enter the middle stage of foundation building, 5 drops can be promoted to the advanced stage of foundation building, 7 drops can be the state of great perfection in the foundation building period, and 9 drops will become the limit state of foundation building.

After the first drop of liquid tire is condensed and formed, it will bring the biggest benefit of promotion to the foundation building period, that is, to build qi veins!

Sure enough, after the crystal clear small droplets of water were condensed and formed, gas-like pipes extended from the small droplets.

These gas-like pipes spread out like a mist formed trachea.

The gas-like pipes began to stretch out like a tree spreading its branches.

These branches, it can be clearly seen, that some of them are thinner, are the ends.

And it is the trunk that is clearly condensed and emits a faint glow.

However, Cheng Li found that this gas-like pipeline, after unfolding the five main trunks, was a little weak.

Cheng Li had a heart in his heart, according to the cultivation system.

The development of the qi veins has 1-2 main trunks for the yellow-level qi veins, 3-5 main trunks for the Xuan-level qi veins, 6-8 main trunks for the earth-level qi veins, and 9 main trunks for the heaven-level qi veins.

If there are only 5 main trunks now, Cheng Li can only build Xuan-level qi veins.

And these qi veins have a very magical function, it is the entire dantian inside, as well as the high-speed channel to communicate with the outside.

Cheng Li can now clearly see that the five main trunks that have been unfolded, one of the main trunks is connected to the void next to the Taiji cyclone.

This nothingness is clearly where the new fluid tire will appear later.

Therefore, the more backbones, the more liquid tires can be directly connected, and the data can be quickly operated through the high-speed channel of the gas vein, which is "mana".

Therefore, in the cultivation system, the qi vein is the foundation for a cultivator to cultivate the spells that have already been cast.

Before there was no Qi Vein, the cultivation and casting of spells by cultivators in the Qi Refining Period, spiritual power and mana power were equivalent to struggling to advance in the wilderness.

And with the qi vein, it is equivalent to building a high-speed channel in the dantian, and its role is naturally extremely important.

There is a saying that goes, "If you want to get rich, you must first build roads." ”

This is also true when it is put into cultivation.

Cheng Li is naturally very clear about this.

Therefore, he did not hesitate to explore his divine sense into the arithmetic tablet that was still in the dantian.

This arithmetic monument is already a foundation for Cheng Li, staying in the dantian.

After receiving Cheng Li's instructions, the arithmetic monument was in the dantian and shone again.

And those qi vein backbones that had been a little stagnant began to spread rapidly in all directions.

One trunk, two trunks...... In the end, the whole nine backbones, like nine keels, supported Cheng Li's entire dantian.

And in the Nine Heavens Trunk, it is the end of the extension in all directions, all over the entire dantian!

And inside the dantian, after all the main trunks are extended, this main trunk finally extends to the wall of the dantian.

Originally, during the Qi refining period, the dantian wall was a barrier with special entry and exit rules.

It only allows the flow of spiritual power that conforms to the dantian key to enter.

Then only the encapsulated mana is allowed to flow out.

Because of this obvious limitation, when a Qi Refining Stage cultivator casts a spell, he cannot store his mana (data) in the four major acupuncture points (memory) suspended in the sea of qi.

As a result, Qi refining period cultivators could only pitifully use the little mana stored along the edge of the dantian to construct spell tricks.

If you look at the image of the computer architecture on the earth, it is like a computer that does not have memory plugged in, but can only rely on the CPU cache to run programs, it must be a drop in the bucket.

However, after the cultivation is promoted from the Qi refining stage to the foundation building stage, the cultivator will no longer be bothered by this problem.

Because those who cultivate the truth in the foundation building period have qi veins!

At this time, Cheng Li saw that the 9 main trunks of the qi vein were extending the Dao Dantian wall and touching the Dao Dantian wall.

I saw that this qi vein actually merged into the Dao Dantian Wall, and then merged with the Dantian Wall.

Subsequently, from the place where the dantian wall and the qi vein were connected, an opening was opened inside, and the place where the dantian wall and the qi vein were connected was actually opened up in this way!

Subsequently, the qi veins drilled out of the dantian wall and began to continue to extend out.

The dantian is suspended in a virtual space three inches below the navel of the human body.

In this virtual space, the dantian is suspended in the center, and around the dantian, it is filled with an endless sea of qi.

Dantian is suspended above this sea of qi!

Around the dantian, the four major acupuncture points Guan Yuan acupoint, Shenvalve acupoint, Shimen acupoint, and Mingmen acupoint occupy four vertical diagonal positions, and the arch guard is in the four vertical directions of the dantian.

Before this, there was no channel connecting these four acupuncture points and the dantian, and only this sea of qi maintained the connection.

Although this sea of qi can be used as a similar "conductor" to transmit spiritual power or mana, its efficiency is naturally relatively low.

And now, from the dantian, the nine main trunks of the qi veins poked out of it.

Then, this qi vein began to spread rapidly in the sea of qi.

At this time, Cheng Li also understood why cultivators would call the qi veins qi veins, because this was completely the qi veins on the sea of qi!

Soon, the main trunk of the Nine Atmospheric Seas, four of which were incomparably accurate, were directly connected to the four major acupuncture points.

The four major acupuncture points suspended in the sea of qi, as soon as they were touched by the qi veins, the root qi veins were completely integrated, and the root dantian wall was the same, and a hole was opened by the qi veins.

As a result, between the acupuncture points and the dantian, a high-speed channel for mana (data) transmission was built through the qi veins!

"If the acupuncture point is the memory and the dantian is the CPU, this qi pulse is equivalent to the front-end bus on the computer!"

Cheng Li couldn't help but immediately use the computer architecture on the earth to make a vivid analogy.

In the earth's computer architecture, the CPU and memory are connected through the front-side bus, so in fact, the qi pulse is equivalent to the front-side bus, which undertakes the direct connection of memory (qi sea acupuncture points) and CPU (dantian) to the high-speed channel.
