The most direct reaction is that two weeks ago, when Xu Tui had just switched to D-level energy replenishing potion, he could not finish one bottle of D-level energy replenishing potion in one training cycle.

It is almost a waste of energy close to a bottle of E-level energy supplement potion.

But now, two weeks later, as Xu Tui continues to open the second level of genetic base points, the total amount of mental power continues to increase, and the overall efficiency of cultivation has also increased again.

Nowadays, after a training cycle, Xu can not only consume a bottle of D-level energy replenishing potions, but also need to take out another bottle of E-level energy replenishing potions before his mental power can almost bottom out and complete a training cycle.

However, the cost of opening the second level of gene base points in "Spiritual Sea Condensation Shensen Basic Forging Method Version 4.9" is getting bigger and bigger.

After continuing for more than half of the training cycle, the seventeenth gene base point of the second level still has not been opened.

Under the illusion of inner vision, Xu Tui's attention switched again.

This time, Xu Tui switched his attention to the fourth gene base point of the Vajra Tide Force Field.

The genetic base points of the Vajra Tide force field are distributed very interestingly.

The fourth genetic base point is actually located under Xu Hui's chin.

To be honest, Xu Tui might not have been able to remember this position if his teacher Shen Jiushuang hadn't personally used his energy field to pierce Xu Tui's body and guided Xu Tui to its position three times.

You have to rely on yourself to locate this gene base point according to the cultivation method of the first layer of the Vajra Tide Force Field. It may not be possible to do it without three to five days of effort.

This is also one of the reasons why genetic ancient martial arts cannot be promoted on a large scale.

There are too many restrictions on cultivation!

Forty minutes later, the fourth gene base point on the first layer of the Vajra Tide Force Field was opened.

With a slight movement of mind, the energy field force in Xu Tui's Dantian instantly appeared at the chin, and the four genetic base points on the forehead, chest, and shoulders that had been opened instantly formed a three-dimensional energy field.

.

In the true internal vision state, Xu Tui grasped the changes in the energy field force in the body extremely accurately.

Is the Vajra Tide Force Field a three-dimensional structural defense of the energy field?

Observing, Xu Tui also came to his own understanding.

The energy field dissipated, and Xu Tui ended today's concentration practice.

But he didn't fall asleep immediately.

Instead, he sat cross-legged and sat down, and began to follow the Little Zhoutian Transportation method taught by Shen Jiu Shuang, using the energy field in the Dantian to guide it with his thoughts, and sequentially patrolled the 18 gene base points of the Little Zhoutian Transportation gene chain that had been opened.

After walking around again, the energy field force returned to the Dantian. Under the true inner vision state, Xu Tui could clearly feel that the energy field force had become slightly stronger.

It seems to be constantly absorbing the energy field force floating at each gene base.

And each of the genetic base points related to genetic ancient martial arts that have been turned on can spontaneously generate energy field forces!

Very miraculous thing.

This makes Xu Tui's cultivation very interesting.

After five consecutive rounds, the training effect became very weak. Xu Tui, who had been practicing for nearly three hours, also felt a strong sense of exhaustion.

Wash.

Go to bed, enter a meditative state, relax mentally, Xu Tui quickly fell into a deep sleep.

However, even when he fell into a deep sleep, Xu Tui still had an obsession in his heart.

Tomorrow, something will happen!
Chapter completed!
