Sun Fei challenged the space in the Nine Walls Mirror again and again, but helplessly, every time after Sun Fei successfully defeated the first three waves of enemies, the difficulty of the fourth wave of Dragon Girl was like a nightmare, no matter what means he tried to attack, there was no way to hurt her in the slightest.

Just when Sun Fei's fiftieth attempt to break through the fourth level failed, Sun Fei suddenly found that he was not sent outside by the Nine Yuan Mirror as before, but was teleported to a mysterious circular room.

The floor of the room was inlaid with a number of circular patterns, each of which was inlaid with beads of different sizes, colors and patterns, emitting a faint light around them.

At this moment, a square stone platform suddenly rose slowly in the center of the circular pattern. At the top of the stone platform is an ancient book with a pale green glow, and the surrounding lines seem to feel the call of the lines and begin to flicker rhythmically.

Sun Fei walked over to the ancient book curiously, and said to himself, could it be that he accidentally turned on some switch just now to let himself enter this space?

There was a faint line of ancient characters on the pages of the ancient book, and Sun Fei squinted his eyes slightly, and chuckled in his heart. The language is difficult to understand, and many ancient languages are recorded in the Immortal Doctor Sutra, and this language is the clan language used by the emperor's clan in ancient times.

"Reach 50 challenges and you will be rewarded with 50 Spirit Points." Sun Fei slowly read out the words on the ancient book.

Just a year after reading it, Sun Fei felt that something was wrong. Spiritual point? What is this?

Just then, another line appeared on the page.

"You can use Spirit Points to improve your cultivation, and when you reach a certain amount of Spirit Points, it will open the way for you to advance."

Almost immediately after this sentence appeared, a small cyan bead located on the outermost circular pattern under Sun Fei's feet suddenly flashed with a brighter cyan light, and then, that cyan light directly entered Sun Fei's body!

Sun Fei was taken aback, and the cyan light quickly dispersed towards the acupuncture points in his body, and almost in the next moment, Sun Fei felt that the meridians in his body were expanded again in an instant.

Unexpectedly, this cyan light actually transformed his already transformed body again, and this transformation made Sun Fei obviously feel that many inexplicable shackles in his body were violently broken, and the plasticity of his body miraculously became better in an instant!

I didn't expect that just unlocking the rewards of the first layer would be of such a great help to my body, and if I accumulated more spirit points, those rewards after that would definitely be more beneficial to me.

It's a pity that there is no explanation of this space in this ancient book, if you have a better understanding of this space, maybe you will be able to use this space for cultivation in a more targeted manner.

At the moment when this thought appeared in Sun Fei's mind, a sentence suddenly appeared in the ancient book.

"If you have any questions, I'll do my best to answer them."

Sun Fei was stunned for a moment, and after thinking about it carefully, since the souls of ancient powerhouses can appear in this space, it is not surprising that there is a "manual" with a soul.

Thinking of this, Sun Fei immediately asked a question that he was most concerned about: "What kind of place is this?" ”

Ancient book: "Here is a part of the sea of knowledge separated from Hongjun Ancestor." ”

When Sun Fei heard this, he was so surprised that his jaw was about to drop. Who is Hongjun Ancestor? That's an almost infinite powerhouse!

When I thought that I was in such a strong person's sea of knowledge, although there was only a small part, the space of this sea of knowledge was too vast and terrifying!

However, what was the purpose of Hongjun Ancestor making this thing? Could it really be a spiritual weapon for the cultivation of one's own descendants?

Thinking of this, Sun Fei immediately asked, "Then, why did Hongjun Ancestor build this place?" Why did I start fighting as soon as I came in? ”

Ancient book: "A hundred strong people lent their spirits to Hongjun Ancestor, and assisted Hongjun Ancestor to seal their spirits in the Nine Walls Mirror to help future generations ascend to immortals and survive the catastrophe." ”

Sun Fei couldn't help but twitch the corners of his mouth, if he could really defeat these strong men, would he still be afraid of that thunder? Not to mention the nine heavenly thunders, even a hundred and thousands of ways are like tickling.

However, if you think about it from another aspect, presumably these powerhouses in the Nine Walls Mirror are still much worse than my real strength, after all, they are divided spirits, and I definitely can't think of them.

The ancient book continued to show the text: "There are only a few descendants of Hongjun Ancestor who are willing to devote themselves to cultivation with the help of the Nine Yuan Mirror, and since then, there are fewer and fewer cultivators with the Nine Yuan Mirror, and the descendants know that the true effect of the Nine Yuan Mirror is less and less, and finally even wandered to the world, and was misused as a sacrifice by the emperors of several dynasties." ”

Sun Fei nodded very understandingly, to be honest, he was still very excited when he used the Nine Yuan Mirror for the first time. But as he was ravaged by the dragon girl again and again, Sun Fei also felt a little depressed, and it was normal for those descendants of Hongjun Ancestor to give up because of this.

At this moment, the ancient book continued to display the words: "When you first enter the sea of knowledge, the Nine Walls Mirror will automatically generate your puppet through the qi you infuse, so as to test your strength. After you complete the third challenge, the Nine Walls Mirror will automatically select a strong person suitable for your cultivation based on your performance. ”

Sun Fei nodded and said, "I see, why did I start fighting without saying a word...... No, wait a minute, isn't that ninety-nine ranked according to strength? ”

Ancient book: "The number does not represent the arrangement of strength, and different strong men have different combat styles." Determined that your combat style is Scouting, he will use Nguyen Ying as your opponent in your fourth challenge. ”

Sun Fei suddenly twitched the corner of his mouth and said, "Then, can you change someone?" ”

Ancient book: "As long as you change your fighting style, you will naturally be able to fight against different strong men." In addition, you can check out the profile of every strong player you've played against so far here. ”

Sun Fei nodded, thinking about it carefully, although he had fought with that dragon girl so many times, he still didn't know much about her, so he nodded and said, "Okay, then let me see the information of that dragon girl." ”

The pages of the ancient book suddenly turned rapidly, and then stopped on one page, and a piece of information appeared on the page. Translated into the current language, it looks something like this:

"Name: Nguyen Ying

Gender: Female

Synopsis: The daughter of the third-generation patriarch of the Fan Ling clan (now in the area of Changbai Mountain) was expelled from the clan by the patriarch of the Fan Ling clan after she could transform into a human form at the age of two. After hiding his identity and coming to the world, he took Ruan Ying's name. Ruan Ying worked as a runner at a young age, accompanied a foot merchant to trade, and even walked with beggars on the street in the most difficult times. At the age of sixteen, when he went into the mountains to collect medicine, he rescued a spirit snake of unknown race, and then took this spirit snake to travel all over the world, while doing business, while inquiring about the whereabouts of his parents. When she was a girl, Ruan Ying's appearance was overwhelming, coupled with her eye-catching long white hair, which attracted the pursuit of many princes, including the son of Emperor Shun. Ruan Ying was distressed by the distractions of the world, and finally decided to walk the mountains and forests with the spirit snake and cultivate on her own. Two years later, when the fierce beast Jiuliu was harming the world, Ruan Ying turned into a dragon and eliminated Jiuliu, and her merits were great, and she ascended to heaven soon after, ranking first among the immortals.

Cultivation: Heavenly Immortals

Skill: Mixed Spirit Dragon Breath, Silent Dragon Pressure, Dragon Jade Collapse

Victory Reward Points: 5,000

Sun Fei saw the name of "Shun", and counted with his fingers, but he didn't expect that there were still mountain dragons on this earth nearly two thousand years ago, and they still existed in the situation of a clan. However, that clan is probably also the last clan of the mountain dragon.

In this way, compared to those strong people in the flood period, Ruan Ying is indeed a "modern" strong man.

In terms of the strength of the dragon, the level of the heavenly immortal did not surprise his expectations, I am afraid that judging from the cultivation of the dragon, this is the starting line. If it weren't for the fact that they had been wiped out during the flood and almost wiped out, at least half of the immortal world would now have to be dragons.

It's just that the strength of this head of the Heavenly Immortals is really a little too terrifying, you know, there are many strengths among the Heavenly Immortals that are comparable to Shang Fang Taiyi Golden Immortals, this kind of strength is really unimaginable!

Thinking that he had been fighting such a monster all along, Sun Fei suddenly felt a little stomach pain.

Sun Fei shook his head, no longer thinking about these things, but changed the question and said, "By the way, if I leave from here, how should I come in next time?" ”

Ancient Book: "After you first obtain a Spirit Point, this room will appear next to you every time you enter the Sea of Knowledge, and you can enter this room before the battle." Use the spiritual points you hold now to improve your cultivation. ”

"Oh, and this! I almost forgot, what the hell is this spiritual point used for? How can I improve my cultivation? Sun Fei asked suspiciously.

Ancient Book: "This is the cultivation you can improve now, please take a look." ”

The ancient book quickly turned the pages again, and then only one item appeared on the page that he could now improve.

"Condensing Qi Technique, Spiritual Points Required: 200 Points."

Sun Fei couldn't help twitching the corners of his mouth, feeling that his spiritual point was not enough to improve other cultivations. Anyway, I haven't heard of the Qi Condensing Secret yet, what is it?

Sun Fei was even more curious, now he could only choose this one, so there was nothing to consider, so he nodded and said, "Okay, just exchange this Qi Condensation Technique." ”

Ancient Book: "I have exchanged the Qi Condensation Heart Recipe for you, and your remaining spirit points are: 0 points." ”

The ancient book quickly turned the pages again, and the cyan ball on the outermost circular pattern suddenly flashed again, hitting a cyan light into Sun Fei's body!

Sun Fei suddenly felt that something suddenly appeared in his mind, and at this moment Sun Fei realized that this Qi Condensing Heart Technique was an auxiliary exercise, an exercise that helped him quickly condense his Xuan Qi outside his body. This exercise allows you to condense the Xuan Qi into the shape you want more quickly and accurately, and the concentration of the condensed Xuan Qi is not comparable to before.

At this moment, Sun Fei suddenly realized that the reward he got was only 50 points, so where did the other 150 points come from?

Sun Fei thought about it, if he has challenged 50 times so far, every time he has been beaten back to reality by Ruan Ying, he has successfully completed 150 challenges, that is to say, every time he completes a challenge, he will give himself 1 spirit point?

Sun Fei raised the corners of his mouth, and suddenly felt that this space was becoming more and more interesting.

Now that you've got a new exercise, why don't you try it one last time!
