In fact, to put it simply, spiritual power is equivalent to human physical strength, and spiritual root is similar to human heart.

By the lake in the inner circle, the spiritual power in the body of the immortal cultivator would be constantly devoured.

However, immortal cultivators can continuously transform the spiritual power in the elixir, or the spiritual energy between heaven and earth, into their own spiritual power through the spiritual root.

This is equivalent to the fact that human beings on the earth are constantly depleting their physical strength when they are exercising, but as long as they can be replenished in time, their bodies will become stronger and stronger.

It's just that in the gym of the earth, human beings can drink some water and eat some food after working out to replenish the energy consumed.

But in the world of immortal cultivators, after the spiritual power of immortal cultivators is consumed, they need to breathe in the spiritual energy of heaven and earth, or take pills to replenish their spiritual power.

Just as human beings on the earth exercise to keep fit, immortal cultivators in the Xianxia realm also need to constantly operate spiritual power to achieve the effect of improving the realm.

This is Lin Feng's current understanding of immortal cultivators, although it is a bit general, but it is roughly what it means.

"This is a holy place to build a foundation, idiot, you seize the opportunity, although you don't have a spiritual root, you may be able to break through!"

Lan Qing sat cross-legged beside Lin Feng, looking full of anticipation, and even said with a little excitement.

Lin Feng stared at Lan Qing's smooth side face, smiling evilly, and actually blushing directly at Lan Qing......

"Rogue ......"

Lan Qing's voice was very small, she came here earlier than Lin Feng, relying on her identity and strength, she directly drove away the other disciples within a radius of a hundred meters, just so that Lin Feng could have a relatively quiet and spacious environment to break through to the foundation.

In this lake, the spiritual power will leave the body on its own, which is equivalent to the calories that you need to run a thousand meters to burn before, and only need one breath to take here, and you can achieve the same effect without even moving.

As the saying goes, the more you use your head, the brighter it is.

In this lake, because the spiritual power will be constantly consumed and replenished, it is of great help to the spiritual roots of immortal cultivators.

The spiritual root of the condensation period is free in the body, and even some people with poor spiritual roots will have the illusion that the spiritual root in the body will disappear at any time, Fan Xiaoqi is this kind of spiritual root......

But such a spiritual root is by the inheritance lake, and after some super intense training, it will definitely have earth-shaking changes.

And the monks of the Great Condensation of Qi are likely to condense the spiritual root directly into the dantian because of this training, that is, to break through the foundation.

This is the difference between foundation building and condensing qi, the spiritual root of the condenser is usually similar to gas and fluctuates in the body, but the spiritual root of the foundation builder is similar to a liquid, which is usually condensed in the dantian position of the immortal cultivator.

Therefore, Lan Qing would have illusions, what if Lin Feng didn't have a spiritual root, but the spiritual root was too weak, so weak that even Elder Dan couldn't find it in person?

So, after Lin Feng cultivated by the lake for a period of time, would the spiritual root suddenly have it?

"Nerd, you must work hard, come on!"

Thinking of this, Lan Qing's head, which was originally shy, raised it slightly, and then saw the corners of Lin Feng's mouth that were slightly raised.

"Girl, do you remember when I said that as long as I can break through the foundation, you will be my girlfriend?"

When Lin Feng said this, a pair of eyes kept looking at Lan Qing's cheeks, and Lan Qing was embarrassed.

I saw Lan Qing stretch out her fist and slam Lin Feng's chest, she felt that there was an inexplicable confidence in Lin Feng's tone, which made her a little worried.

"You break through first, let's talk about it, break through the ......"

Lan Qing thought, give Lin Feng a hope first, lest this nerd not be careless when he cultivates.

Of course, Lin Feng had confidence, he glanced at his immortal cultivation experience points, he could have been upgraded to the first level of foundation building a long time ago, and even because he had eaten a lot of small tonic pills in the past few days, he had thirty or forty thousand extra experience.

Moreover, the most critical point was that Lin Feng did not have a spiritual root, which caused him to not consume spiritual power by this lake.

Because, Lin Feng never had spiritual power, but used thunder and lightning ability......

Of course, it was also tiring to use the lightning ability all the time, so Lin Feng would occasionally take a sip of Sprite and eat a few small tonic pills.

This scene, in the eyes of others, was as if the thunder and lightning spiritual power in Lin Feng's body had been withdrawn from his body, so Lin Feng needed to keep drinking spiritual liquid and eating small tonic pills in order to replenish the spiritual power consumed in his body.

"Girl, can you swim in this lake?"

Lin Feng suddenly asked, he hadn't taken a bath for several days.

"Absolutely not, when we are by the lake, the consumption rate of spiritual power is already very fast, and if we jump into the water, the consumption rate of spiritual power will become very terrifying.

Therefore, if you jump into the water and swim, the consumption rate of spiritual power, once it exceeds the absorption rate of the spiritual power of the elixir, it will consume the vitality in your body like Fan Xiaoqi! ”

Lan Qing categorically stopped Lin Feng's idea, because when she first came to this lake, she had thought about washing her hands with lake water.

As a result, as soon as her hand reached into the lake, the acceleration of the loss of spiritual power made her immediately stop this thought.

"That's ......"

Lin Feng smiled slightly and put his hand into the lake.

Sure enough, as Lin Feng expected, he had no spiritual power, so this kind of lake water that would devour spiritual power was no different from ordinary water for him.

Even, when Lin Feng stretched his arm into the lake water, there would be a very comfortable feeling of coolness.

But just as Lin Feng was enjoying this feeling, Lan Qing suddenly pulled Lin Feng back, took out a few pills that replenished spiritual power, and fed them directly to Lin Feng.

"Idiot, are you crazy?"

Lan Qing felt that Lin Feng must be too anxious to break through the foundation, so he would use the method of contacting the lake water, which consumes spiritual power at a higher intensity, to activate his spiritual root.

It's so adventurous!

Lan Qing was a little hesitant, if she was asked to choose between Lin Feng's life and cultivation, of course she would choose to let Lin Feng live well.

Lin Feng pondered for a while, he was thinking about how to explain to Lan Qing that he was not afraid of these lakes at all?

But he saw that Lin Feng suddenly stood up, looked at the white mist in the center of the lake with his chest straight, and his eyes showed a resolute expression.

"Girl, success is to work harder than others!

In itself, my talent is not as good as yours, and I don't have a spiritual root yet, so if I'm like you, just staying by the lake and meditating and practicing, then when will my cultivation catch up with you?

When will I be able to fulfill my promise to protect you? ”

With his hands behind his back, Lin Feng left Lan Qing with a somewhat thin back.

But when Lin Feng's voice sounded, Lan Qing felt that the back was so majestic, it seemed that it could really help her block all the anxiety and fear.

"Girl, you know, I'm an alchemist, I have small tonic pills, big tonic pills, and as much spiritual liquid as the lake in front of me......"

Speaking of this, the corners of Lin Feng's mouth twitched suddenly, and he felt that it was always a bit strange to say that Sprite was spiritual liquid.

So, Lin Feng turned his head slightly to look at Lan Qing, who was still sitting on the ground.

"So, please rest assured, I know very well whether my absorption rate of the pill can keep up with the consumption rate of spiritual power......"

The sunset was very beautiful, shining on Lin Feng's side face, only to see Lin Feng suddenly stretch his hands to his waist and start to untie his clothes.

Then, just listening to the sound of "plop", Lin Feng jumped into the lake that reflected the afterglow of the sunset.

Lan Qing's face turned even redder, and she even forgot to cover her eyes with her hands......
