With a lifespan of nearly 71 years, you can do a lot of things!

However, for the current Qin Feng, the most important thing is to improve his qualifications - although, according to his understanding of this world, even if he just relies on his current orange qualifications, he can still climb to the top, but he also knows that the higher the qualifications, the more effective it will be to practice, since he can use the least time to gain stronger strength, then ...... Why did he have to suffer that "suffering"?

Although the promotion qualification needs to consume one's own time to redeem, but, as Alice comforted before, as long as his strength can continue to "advance", those lost time will one day be cultivated back by him again.

Therefore, after Qin Feng pondered for a while, he opened his mouth to ask about the time "price code" of the exchange qualification.

"Alice, how long does it take to redeem the yellow qualification?"

"Ten years!" Almost without thinking, Alice gave an answer that was unexpected but reasonable.

It is true that when he exchanged for orange qualifications, the time spent was 100 years, and the yellow qualifications, according to the "ranking", are above the orange qualifications, and the amount of time required to exchange them seems to be higher than the 100 years of exchanging orange qualifications, which is only reasonable - however, don't forget, because red qualifications "can't practice martial arts to the 'acquired' realm" Therefore, it takes a hundred years of exchange time to promote the orange qualification, and only ten years of exchange time to promote the yellow qualification, which is a more reasonable exchange offer.

And the explanation that Alice gave to Qin Feng next was also consistent with Qin Feng's guess.

"That'...... How long does it take to redeem green qualifications?" Qin Feng asked again.

"One hundred years!"

"......" Qin Feng was slightly embarrassed - he had just arrived at the "big handful" time, and the result was ...... You can only advance to the first level of qualification.

"Forget it! Forget it! Level 1 is level 1, it's better than nothing!" Qin Feng comforted himself for a while, then entered the system interface and exchanged the yellow qualification for himself.

"So what's next...... You need exercises to cultivate!" Qin Feng couldn't help but groan again.

Originally, under Qin Feng's original situation of "time is running out", his primary goal was to choose to plunder Mu Tian's opportunity-the mysterious "Pranayama Sutra" to build a foundation, but now, he still has nearly sixty-one years to lay the foundation, so ...... Do you still choose the "Pranayama Sutra" to build the foundation...... It's something worth reconsidering.

"Let's see—anyway...... There are still three days left before the day of the 'Library Pavilion' to pick up books!" Qin Feng's eyes narrowed slightly, as if he had seen the near future.

............

Library Pavilion - the place where the Mu family stores martial arts cheats!

All the children of the Mu family have the opportunity to enter the book pavilion once a month to select books - and Mu Shuiqing gave this opportunity to Qin Feng.

In the Mu family, the opportunity to pick up books could be transferred to the servants—usually, this was the "master" as a means of rewarding the diligent servants.

As expected, Qin Feng saw Mu Tian in the crowd of people picking books - in the novels written by Qin Feng in his previous life, Mu Tian took an olive branch from Mu Changfeng, which led to this book selection trip.

And it was during this book selection trip that he got the mysterious "Pranayama Sutra", and his legend began.

Originally, Mu Tian was a servant under Mu Shuiqing, but when the "power of the head of the family" was declining, he decisively "defected" and became Mu Changfeng's lackey - and then, with his courtesy and "means" of flattering and bullying, he successfully got this opportunity to pick up books.

In this life, as Qin Feng expected, Mu Tian ...... I still chose this path.

In fact, Mutian's choice is understandable - people go to high places, and water flows to low places!

Not to mention...... He's just a minion!

However, since the "choice" has been made, the "price" that ...... will need to bear after the "choice" also needs to be prepared, after all, in this world, there is no reason to ...... You made a choice without paying a price......

If that's the case, wouldn't that be too fateful?

As for Qin Feng's original idea of keeping Mutian in order to obtain greater benefits, he had long been left behind - he would not let go of anyone who dared to betray his family Qing'er.

What's more, now that he has a "big time system" in hand, the "leeway" for manipulation is a little bigger!

............

"Knock ——!!!"

"Knock ——!!!"

"Knock ——!!!"

............

Just when Qin Feng's thoughts were confused, the bell of the Library Pavilion also rang at this time.

"Boom ——!!!"

The heavy sound of the bell was accompanied by the dull sound of the door of the library slowly opening.

"Whoop——!!!

The golden light flashed, and an aura that seemed to be filled with the meaning of endless tyranny suddenly filled this piece of heaven and earth, giving endless coercion to everyone present.

Qin Feng retracted his mind, slowly looked at the golden light in front of him, and couldn't help but reveal a touch of irrepressible excitement.

When Qin Feng wrote "Martial Arts" in his previous life, because he often interrupted the update, he always liked to send some two or three hundred words of "biography" in the "work related", in order to alleviate the resentment of those readers who urged them to change - originally Qin Feng was still a little worried that these chapters that were not counted in the "main text volume" might not be "staged" in this world, but the result was obvious, his luck was strong enough, and what he wrote in his spare time was angrily denounced by some readers as "crooked and heretical" 's Gaiden chapter, which perfectly "fits" with this world!

And the golden light that aroused Qin Feng's interest was the place where a powerful exercise in the "Gaiden" came from, and it was also the purpose of his trip.

In his previous life, on a whim, Qin Feng wrote down such a slightly illusory source of the exercise in the "Gaiden"—and today, he will be in the golden light of this "place he created...... Take it!

"But...... Don't be busy, take your time!" Qin Feng couldn't help but show a deep smile.

"Click", "click", "click", ......

............

The mermaids rushed in and entered the library pavilion.

As soon as I entered, I saw the books hanging on the beams, exuding a colorful luster, like poppies, seducting the soul, making people reluctant to look away for a moment......
