It was indeed Xiaoxue who wanted to be dirty.

When Xu Tui explained clearly to An Xiaoxue what he called dual cultivation, An Xiaoxue blushed in anger at Xu Tui's laughter.

Then, Xu Tui received another solid kick on the butt.

But the consequence of this kick was that Xu Tui and An Xiaoxue first started a false double cultivation with a negative distance, and then started a 'real' double cultivation!

Xu Tui's so-called 'true' dual cultivation is actually Xu Tui's realization these days when he was practicing to build a mental barrier within the chain.

After Cai Shaochu helped Xu Tui build a mental barrier within the chain to break through, the question Xu Tui thought about the most was how to help others break through.

Xu Tui has been thinking about this issue for a long time.

The first choice targets are Yan Lie and An Xiaoxue.

The main reason why these two people were able to practice like this was that Yan Lie and An Xiaoxue had absolute trust in Xu Tui.

Building a mental barrier within the chain requires mental power to invade the opponent's body. To a certain extent, the mental power entering the opponent's body is not much different from the nature of negative distance contact.

These days, Xu Tui himself continues to use this method to quickly improve his cultivation level, and continues to realize it.

Only when you have a thorough understanding of yourself can you help others, otherwise you will harm others.

He does not have as strong mental power and control as Lao Cai.

In the end, Xu Tui chose An Xiaoxue instead of Yan Lie as his first assistant training partner.

Help An Xiaoxue build a mental barrier within the chain, because An Xiaoxue can also see inside, so it should be easier and more convenient.

Of course, Xu Tui and An Xiaoxue's cultivation method can be called dual cultivation!

With Yan Lie, that’s absolutely not possible!

Listening to Xu Tui constantly explaining to her the details and precautions in the process of 'real' dual cultivation, An Xiaoxue, who had just completed 'fake' dual cultivation with Xu Tui, had a pretty face and blushed, and her beautiful eyes became brighter and brighter as she listened.

It is possible to try out such a shortcut to cultivation. Although the scope of applicability is not large, this is already a historic innovation.

Because even if the scope of applicability is not large, this cultivation method can allow a small group of elites to quickly break through to the realm of transformation.

The elites of the transmutation realm have the strength to fight against quasi-planets.

It is of great significance.

After explaining it clearly, Xu Tui and An Xiaoxue began to practice dual cultivation. Even though An Xiaoxue had been penetrated by Xu Tui many times, Xu Tui's mental power directly invaded, and she still let her

"Xiaoxue, which genetic ability chain do you want to build the inner loop in first?"

"Dimensional explosion, I will guide you."

The first time is always a little difficult, even a little painful. Three hours later, An Xiaoxue saw blood in her mouth and nose, and her pretty face was pale, but there was joy in her pale pretty face.

Done!

The first intra-chain internal cycle of the dimensional explosion gene ability chain in her body was successfully established.

Feeling her obviously improved aura, An Xiaoxue pondered for a while before saying, "Xu Tui, I don't think your method is a shortcut to cultivation."

"Isn't it a shortcut to practice?"

"This should be an innovative cultivation method, not what you think is a shortcut in cultivation. Shortcuts in cultivation are tricks.

And this method of building a spiritual barrier is actually not a trick, it is just a clever way to shorten the accumulation time from the breakthrough of the evolution realm to the transmutation realm.

Moreover, the amount that needs to be accumulated has not decreased.

I feel that after building the first inner loop branch, my speed of absorbing source energy has also accelerated.

There should be a period of rapid improvement in my strength." An Xiaoxue said.

"It's the best if your strength can increase rapidly." As he spoke, Xu Tui directly took out a kilogram of source crystals and placed them in front of An Xiaoxue.

"Use it for practice first, then use it up."

In fact, when he said this, Xu Tui felt a little guilty. He only had more than 2,000 grams of Source Crystal on his body.

An Xiaoxue glanced at Xu Tui, said nothing, took it, and the two continued to practice.

However, after the first day of dual cultivation, Xu Tui and An Xiaoxue achieved true dual cultivation.

Just help each other cultivate.

During his previous training, Xu Tui built a mental barrier for himself, and then absorbed source crystals to continuously accumulate energy to break through.

It's equivalent to two uses of distraction.

It is even said that most of the mental power and attention are used to build a mental power barrier. The mental power is consumed quickly and the Source Crystal is absorbed slowly.

Previously, it would have been good if Xu Tui could build two to two and a half chain inner loops a day.

However, instead of dual cultivation with An Xiaoxue, An Xiaoxue would use her mental power to build a mental power barrier within Xu Tui's corresponding genetic ability chain, and then Xu Tui would absorb the source crystals with all his strength to practice.

In this case, the speed of cultivation can be said to be doubled.

Basically, it took less than an hour and a half to use energy to create a new internal circulation branch. Through continuous practice, Xu Tui himself also realized many tips for constructing internal circulation branches.

An Xiaoxue's speed is also constantly improving.

At first it took three hours to build an inner loop branch, then two hours, and now, it takes about an hour and 45 minutes to build an inner loop branch.

After practicing hard for a day, Xu Tui could build five to six inner circulation branches, and An Xiaoxue could also build five.

The strength of the two of them can be said to have improved rapidly.

But this speed of cultivation could not be sustained after only three days.

Source Crystal!

The source crystal consumption is too high.

The amount of source crystals that need to be absorbed to open an internal circulation branch ranges from about 50 to 100 grams of source crystals.

After practicing for three days, the source crystals in their hands were all gone.

But in three days, the strength improvement was also huge.

In three days, Xu Tui added a total of sixteen internal circulation branches. Counting the internal circulation branches added before, the number of internal circulation branches in Xu Tui's mental whipping gene ability chain has reached 28.

The complete internal loop state of the mental power whipping gene ability chain is fifty-five internal loops. Under normal circumstances, most practitioners start trying to condense stars after one-third of the internal loop branches of a certain gene ability chain are completed.

.

If the inner loop branch is halfway completed, it will definitely try to condense the stars.

Try to condense the stars, that is, break through to the quasi-planet!

Xu Tui currently has 28 internal circulation branches, which is already more than half of the perfect cycle. From this point of view, Xu Tui can try to break through to a quasi-planet at any time!

If the breakthrough can be successful!

However, Xu Tui is not in a hurry to break through to the quasi-planet!

Others can't do it because they are in a hurry.

As for Xu Tui, what he lacks is the Source Crystal, so Xu Tui wants to try the perfect internal circulation and see what a breakthrough in the perfect internal circulation state will be like!

Similarly, An Xiaoxue's improvement is also rapid. The internal circulation within the genetic ability chain of her major has exceeded one-third!

As long as she waits for a period of time and waits for the main gene ability chain to complete the internal cycle to spontaneously strengthen the body, An Xiaoxue can even try to break through to the quasi-planet.

Whether it will succeed or not is hard to say.

Of course, An Xiaoxue would not break through in such a hurry. Like Xu Tui, she had plenty of time to accumulate.

"I'm almost running out of source crystals, where's yours?" An Xiaoxue said suddenly during a break in practice.

Xu Tui looked embarrassed after hearing this.

What is the most embarrassing moment for a man?

Just not when a woman needs it.

Whether it is certain abilities or wealth.

What Xu Tui is lacking now is Source Crystal.

"Xiaoxue, the source crystals are a little nervous at the moment. The main reason is that our cultivation consumes too much. I'll get some more after I'm done!" Xu Tui smiled bitterly.

"Tough talk."

An Xiaoxue rolled her eyes and took out a bag from her bag, "Use these first."

Opening the bag, Xu Tui took one look and was shocked.

"So much? It's not 3,000 grams, but more than 2,000 grams, right?" Xu Tui was surprised.

"When I participated in land reclamation, I brought a lot of supplies with me, and Teacher Ji and Teacher He also transferred a lot to me. Of course, the consumption was also huge.

But part of it is what we gained from Laita Star." An Xiaoxue said.

"What's gained from coming to Tower Star?" Xu Tui was a little confused.

"Do you know why we established that shelter base deep underground on Laita Star?" An Xiaoxue asked suddenly.

"Why? Isn't it for defense and survival?"
