With these thoughts in mind, Chu Yingfei became even more frustrated, and her gaze towards Bai Li Hongzhuang was filled with displeasure.
With the help of the Return Qi Pill, Bai Li Hongzhuang's internal energy quickly recovered and restored to its original state in a short period.
However, Bai Li Hongzhuang wasn't in a hurry to reenter the Wind Gorge. Instead, she pondered on how to make her internal energy last longer in the gorge.
Clearly, it was impossible to have enough internal energy to sustain two hours in such circumstances.
She had no idea how long it would take to gain the necessary strength.
Since her master and Elder Xu instructed her to train here, there must be other methods that could help her endure for a longer time.
Therefore, rushing back into the Wind Gorge wouldn't serve much purpose.
Her previous entry into the gorge was only to understand its characteristics and how long she could last. Now that she had a certain understanding, she needed to figure out what she should focus on improving and what methods she should employ to continue enduring.
After all, she was different from the other core disciples.
While others had plenty of time to cultivate, she had to seize every moment. Therefore, she had to pass the trial of the Wind Gorge as quickly as possible to move on to her master's other assessments.
Given the limited amount of internal energy she possessed and her desire to endure for such a long time in the Wind Gorge, the only solution was to control the dissipation of her internal energy, slowing down its depletion.
Only then could she last for a longer period.
After careful consideration, Bai Li Hongzhuang understood the root cause.
However, achieving this goal was by no means an easy task.
Clearly, it required practitioners to improve their control over their internal energy, enabling them to wield it more precisely.
This feeling was similar to when one practiced martial arts, where the principles might require only 10%, but many undisciplined practitioners would use up 20% or even more.
As a result, they would be at a disadvantage in combat.
Bai Li Hongzhuang had some understanding of this from her past life, and even the old folks in her family had specifically taught her about it.
However, precise control of internal energy was not an easy task, and there were no suitable conditions to practice this aspect.
Practitioners could only learn to control it as they practiced their martial arts.
Unexpectedly, the Infinite Palace had a method to train this aspect, which was truly rare.
Upon arriving at the sect, Bai Li Hongzhuang discovered that the current sect had many more advantages compared to a few years ago.
After realizing this, Bai Li Hongzhuang no longer hesitated. Controlling her internal energy was not something she could accomplish just by thinking about it. Only through continuous trial and practice could she possibly achieve this goal.
Bai Li Hongzhuang was fully prepared. In the process of continuous experimentation, she gradually grasped this method.
When she entered the Wind Gorge again, she didn't rush towards the location of the red line. Instead, she meticulously controlled her internal energy, minimizing its consumption.
Her spiritual power spread out, carefully sensing every subtle change in her internal energy.
