Ding!

[The reason is simple. The [Yin and Yang Chaotic Formula] is much more profound and harder to comprehend than [Heavenly Sword Immortal's Manual].]

[Moreover, this [Heavenly Sword Immortal's Manual] already contains the detailed note from Heavenly Sword Immortal, including all of his experiences and insights, so comprehending all of them will not need to take too much effort.]

[The price actually will be much lower if not for the sheer amount of contents of this [Heavenly Sword Immortal's Manual] that covers all of Heavenly Sword Immortal's lifetime knowledge about martial arts and cultivation.]

Tang Li Xue nodded in understanding after she heard the explanation from her system.

'All right then... Let's begin now since we only have thirty minutes to comprehend all of them!' Tang Li Xue thought, but she started to hesitate for a few moments.

'Sigh... After I look at it again, there are so many of them. I wonder if my mind can withstand it... Oh, well... It is already too late to back out from this after going this far anyway. YES!' Tang Li Xue steeled her will and approved to spend 700 of her Deity Coins to comprehend all of the contents of the ancient murals.

BAAAAAAAANGGG~!!!

All of the information from the ancient murals flooded Tang Li Xue's mind in an instant like a great tsunami.

Tang Li Xue gritted her teeth to withstood the unbearable stinging pain that almost broke her mind.

It had been a while since she felt this kind of pain since her mind already strengthened a lot after she increased her Spirit stat to 1100.

The last time she felt this level of pain was when she used her system to comprehend [Four Mythical Guardian Beasts Art] in Asura Demon Sect before.

But at that time, she still did not have Spirit stat in her system's stats yet, so she could not strengthen her mind like now.

The splitting headache made Tang Li Xue's body covered with cold sweat.

She staggered and fell on her knees, then she pounded her fist onto the ground to vent out her pain.

BOOM~!!!

"GUUUUUUUUAAAAAAARRRRHHHH~!!!" Tang Li Xue held her head and shouted in pain.

Even Little Loki was caught off guard by Tang Li Xue's exaggerated reaction and jumped out from Tang Li Xue's embrace.

Little Loki did not know what happen to Tang Li Xue, and it started to become anxious and panicked since it did not know what to do to help Tang Li Xue.

Nyaaawww~!

Little Loki jumped onto Tang Li Xue's right shoulder and licked Tang Li Xue's right cheek as if it tried to comfort Tang Li Xue and asked what happen to her.

However, Tang Li Xue was currently using all of her strength and mind to withstand the unbearable pain, so she did not have time to pay attention to the worried Little Loki.

Thankfully, the unbearable stinging pain only lasted for a few minutes before it subsided bit by bit, which mean that the comprehension process was finally over.

All of the knowledge contained in all ancient murals in this cave already entered Tang Li Xue's mind, but it might take quite a long time for her to process everything.

At least she already got all of the knowledge, and she could pass this last trial easily.

Of course, executing or learning all of the martial arts or cultivation techniques from those ancient murals was a different matter altogether.

Fortunately, there was no requirement for her to execute any martial arts or cultivation techniques from those ancient murals or she might fail this last trial since the martial arts or cultivation techniques from those ancient murals were on a different level than the previous four sword techniques at the second trial.

"Cough… Cough… Cough… Damn it! That was truly intense… Huff… Huff… That kind of pain… I really do not want to feel it anymore… Huuuffff…" Tang Li Xue murmured while panting in exhaustion.

The cold sweat on her face kept dripping onto the floor as she supported her body with her hands in a kneeling position.

In fact, she really wanted to lie down on the ground for a few minutes to take a rest, but she did not want to make Little Loki more worry, so she decided to sit on the ground instead and embraced Little Loki again.

Little Loki kept staring at Tang Li Xue's face with a worried expression.

Tang Li Xue smiled gently at Little Loki and patting its tiny furry head, then said: "What's wrong, Little Loki? Are you worried about me? Hehe... You do not need to worry. I am alright. I only use some secret methods to comprehend all of these ancient murals. It was a bit painful, but the pain has vanished now."

Tang Li Xue already spent about ten to fifteen minutes, so she decided to do a quick review of all of the content of ancient murals in her mind in her remaining time.

After another fifteen minutes had passed, the archaic voice suddenly whispered into Tang Li Xue's mind again: "All right, it is already thirty minutes. Your time is already up. Are you sure you already comprehend everything in these thirty minutes? I can still extend your time to one week if you regret it and beg to me now."

Tang Li Xue's pink lips twitched violently in anger when she heard the Tomb Owner's Will asked her to 'beg' him.

"Hehehe... Easy peasy~! I already memorize and comprehend all of them! These things are not even a challenge for me. If not for the sheer amount of contents of these... ancient murals, I can even comprehend all of them in less than one minute!" Tang Li Xue muttered with a mocking tone.

It was as if she was trying to say: 'All of these are your entire life experiences and insights in cultivation and martial arts?! Are you stupid or something?! Look, I can comprehend all of them in only thirty minutes!'

The Tomb Owner's Will still felt skeptical at Tang Li Xue, so he replied: "Okay... then I will test how far you comprehend the content of these ancient murals right now. I will ask you some random questions from the content of the ancient murals, and you only need to answer them."

After that, the Tomb Owner's Will asked ten questions to Tang Li Xue, and all of his questions were really taken randomly from some parts of the ancient murals.

Even though Tang Li Xue had not processed almost all of the knowledge she just got from ancient murals, but Tang Li Xue could still answer all of the Tomb Owner's questions really easily.

It was like a teacher gave an oral quiz to a student, but the student actually already memorized all the answers beforehand.

The Tomb Owner's Will became speechless for a few minutes in astonishment, then he started to ask Tang Li Xue another ten questions, but his questions were much harder to answer and more profound than the previous questions.

Fortunately, his questions were still from the content of ancient murals, so Tang Li Xue could still answer all of them easily.

The Tomb Owner's Will muttered with a dispirited tone as if he began to question the meaning of his life: "Sigh..... You... have... passed the last trial..."

Tang Li Xue smiled triumphantly as she grasped his fist tightly and made a victory pose while Little Loki still sat on her right shoulder.

"All right! Since I already pass all of the arduous trials with so much difficulty, it is time for me to claim my reward. Where is your inheritance?" Tang Li Xue said as she licked her pink lips and rubbed her palms impatiently.

"No, no, no... This is impossible! I still cannot believe it at all! You must be cheating!" The Tomb Owner's Will shouted in Tang Li Xue's mind with his archaic voice.

Tang Li Xue rolled her topaz blue eyes in disdain and replied with an angry and chilling tone: "Old man, this is the second time you accuse me of cheating! Do not test my patience and bottom line, or I will make you will regret it later!"

"Cough... Cough... I am sorry... It is not my intent to do so... But this is just too unbelievable. Just one more test, okay? I will test your comprehension of these ancient murals one more time. I promise I will not doubt you anymore and lead you directly to the place of inheritance after that. I just need to make sure for one last time. How about it?" The Tomb Owner's Will sounded guilty, but he still asked Tang Li Xue with a begging tone.

Tang Li Xue felt angry and really unwilling to take another test, but she did not have any other choice.

'Okay, he said that he only wanted to test my comprehension of the content of ancient murals... It should be easy for me, and it will not waste too much of my time since I already comprehend all the content of the ancient murals anyway.' Tang Li Xue thought as she calmed down.
