Ji Xueyu had a bit of obsessive-compulsive disorder at this time. The more he couldn't open it, the more he wanted to open it.
But she couldn't find a way to open it, which made her anxious and restless.
Ji Xueyu forced herself to calm down and prepare to think carefully.
"First of all, I have to determine whether this box has a second layer. If not, then everything I do will be in vain."
Ji Xueyu murmured to himself, his head spinning rapidly.
She didn't know if there was a second layer, but she knew that Lu Feng had told her that there was a high probability that this box had a second layer, and Ji Xueyu would naturally believe Lu Feng's words.
Therefore, Ji Xueyu now assumes that this box does have a second layer.
"Then, this box was given to Lu Feng by someone else. The purpose is to help him improve his strength. Naturally, the more it can help Lu Feng, the better."
"But since the other party wants Lu Feng to improve his strength, then why can't Lu Feng open the second level?"
Ji Xueyu thought about this question carefully while continuing to look through the box.
First of all, since the other party wants to give Lu Feng this box, he must want Lu Feng to get more help.
So the reason why the second layer is so difficult to open is that if someone else gets this box, they can't let others get the items on the second layer.
But if it was just for this reason alone, then when the other party gave the box to Lu Feng, he would definitely tell him how to open the second layer.
But the problem now is that the other party didn't tell Lu Feng how to open the second floor.
Under this situation, how can Lu Feng improve his strength and get more help from this box?
"Is there a possibility that Lu Feng didn't need the second level before, or that he could only open the second level after reaching a certain level of strength?"
"If you rush into martial arts training, it may be counterproductive..."
This thought suddenly flashed through Ji Xueyu's mind.
She is not a novice martial artist now, but a genuine ninth-grade grandmaster, so she also knows many things about martial arts.
In the path of martial arts cultivation, you can pursue speed, but you cannot pursue speed blindly. People like Ji Xueyu are completely outliers, and for most martial artists, they must improve step by step and step by step.
If you are eager for success, you will want to run before you have learned to walk, and you will definitely fall down.
Just like Ji Xueyu is now a ninth-grade grandmaster, the power in her body is already very powerful. If this power in her body were given to an ordinary person or a sixth-grade warrior, the other party would definitely not be able to withstand it.
Why?
Because with the progress of martial arts cultivation, Ji Xueyu's current physical fitness is fully able to withstand the power of a ninth-grade grandmaster, but if he has not reached this level, he may not be able to withstand it.
Just like a car tire, it must be made of a material that can withstand the air pressure. If the tire is made of plastic, it will burst with just a little bit of air.
The same principle applies to martial arts. Strength can be increased, but the strength of the body as a carrier must also be increased accordingly.
Otherwise, no matter how much force is given to you and your body cannot bear it, the final result will definitely be bad.
Thinking of this, Ji Xueyu felt that she was getting closer and closer to the answer.
"Is there a possibility that Lu Feng couldn't open the second floor at that time because he couldn't bear the things on the second floor with his strength at that time?"
"So, this is actually a kind of protection for Lu Feng?"
"And what if Lu Feng can open it after his strength reaches a certain level? Then how can he open it?"
Ji Xueyu narrowed his eyes slightly. Is there any difference between Lu Feng at that time and now?
There is a difference.
As a ninth-grade grandmaster, Ji Xueyu knows very well that the realm of a ninth-grade grandmaster and the realm below the ninth grade are completely different.
Moreover, the biggest difference is that the ninth-grade grand master can use internal energy at will, and when fighting a warrior, he can use internal energy to penetrate the opponent's body, causing greater damage.
Therefore, the ninth-grade Grandmaster is also called the Neijin Grandmaster by many warriors.
Of course, this internal energy must have a medium, which means that when fighting with a warrior, the internal energy can be overcome through physical contact.
As for the power of exerting inner energy from a distance, Ji Xueyu has never seen it before, and he doesn't know if there is such power.
"Is it possible that when Lu Feng reaches the ninth level and has internal energy, he can open the second level?"
Ji Xueyu thought about it and found that it was very possible.
If her previous guesses are all correct, then the key to unlocking the second level must be the inner strength of a ninth-grade master.
And now, Ji Xueyu is also a ninth-grade grandmaster and can skillfully use internal energy, so can she try it?
Thinking of this, Ji Xueyu felt a little excited, and then she slowly sat down, controlling the internal energy in her body, while her palms were tightly attached to the bottom of the first layer of the box.
Immediately afterwards, Ji Xueyu felt the inner energy slowly flowing into the box through her palms.
"Crack."
The moment the inner energy entered from the bottom of the first layer, the small box made a crisp sound.
The sound was like the sound of unlocking, and Ji Xueyu's palm also felt the faint vibration coming from the box.
However, after the sound, the small box showed no sign of being opened.
Ji Xueyu paused for less than two seconds, then controlled his inner strength again and entered the small box.
"Click, click, click."
Ji Xueyu discovered that when she controlled her internal energy and exerted force from left to right, bursts of sound came from the bottom of the box, like the sound of gears turning.
Moreover, as the sound continued to sound, the bottom of the small box became higher than before.
Ji Xueyu knew that he had found the right direction, so he continued to control his power and slowly turned in the direction just now.
"Ka! Ka ka ka ka..."
The sound of the gears turning became more and more intensive, and the bottom rose higher and higher.
At this moment, Ji Xueyu was extremely excited. It seemed that she had found the right method this time.
Only after reaching the realm of a ninth-grade master and being able to skillfully control one's own inner energy can one open the second layer of this box.
At this time, Ji Xueyu also had great expectations in her heart.
It can only be opened with the inner strength of a ninth-grade master. It can be imagined that the things on this second level are absolutely very precious and will definitely be of great use to warriors in the realm of ninth-grade masters.
Thinking of this, Ji Xueyu couldn't control his impatience and immediately increased his strength.
However, after Ji Xueyu increased his internal energy, he found that the bottom that was rising slowly stopped rising, and the sound inside stopped coming out.
"Isn't it possible that the power is too great?"
Ji Xueyu reacted quickly and then weakened some of his strength.
Sure enough, after she weakened some of her strength, the bottom of the box continued to rise slowly.
This time, Ji Xueyu didn't dare to be anxious, and controlled a moderate amount of power to spin slowly.
