The top priority is to restore Radha to its peak strength, and even if he participates in the king-level power battle at that time, he will be sure to defeat his opponent!

The problem of the water of youth is difficult to solve, so simply refine the precious life-prolonging potion!

Life extension elixir is to continuously purify a large amount of vitality, achieve qualitative change, and prolong life, so each quality can only act once, ordinary quality is ten to twenty years, and the value needs five million to twenty-five million contribution points, while the rare one, prolonging life for twenty-five to fifty years, is worth 50 million to 250 million contribution points!

The life-prolonging treasure of the life-extending elixir must be a restricted item of the alliance, and if you want to exchange it, you can either make meritorious service to the alliance or become a heavenly king!

Bai Yuling was originally refining a life-extending elixir, which was difficult to say, but it was actually quite simple, after all, he had only refined it three times.

However, the life-extending elixir of the treasure cannot be refined by a non-master-level doctor of pharmacy, and it also requires a variety of expert knowledge, and the difficulty is at least ten times higher than that of ordinary quality.

Even if Bai Yuling's waveguide is no longer what it used to be, or even advanced, there is no certainty that it can be refined. This is also the most difficult potion formula for Bai Yuling to master.

But it doesn't matter, he is not now when he only had tens of thousands of contribution points, he has obtained nearly 40 million contribution points in the alliance competition, just exchange materials, plus refining by himself, the cost is not even one percent, but unfortunately those unknown vitality materials are too few, otherwise the cost can be reduced several times!

Bai Yuling immediately went to the World Center and exchanged twenty materials in one go, so that some of the materials were vacant, which surprised the members of the alliance who monitored this, and hurriedly reported it.

The alliance inquired for a while to no avail, and after another speculation, it finally gave up reluctantly.

The White Feather family naturally has a special research institute, and the configuration in it is the top one they can exchange. It's no worse than a doctorate-level research institute.

Two hours later, Bai Yuling, who failed for the sixth time, once again reflected on his mistakes and omissions, and at the same time kept simulating in his mind.

Half a day later, the last piece of material turned into residues, and it was still a failure.

'Life extension agents (failure products) can extend life by two years, and there may be side effects.

'Life extension agents (failure products) can prolong life by three years, and there may be side effects.

Two bottles of failure, this is Bai Yuling's entire harvest.

Millions of contribution points are gone.

Bai Yuling's face was calm, this was originally expected by him, the center of the world, Bai Yuling continued to exchange twenty materials, because of the price control, the price was obviously a little higher.

The thirtieth failed, and after Bai Yuling's deduction was completed, Bai Yuling, who was exhausted, fell asleep directly on the floor.

The next day, Bai Yuling, who was full of spirit, ate some food casually and continued refining.

Bai Yuling strives for perfection, because the life-prolonging elixir can only be used by himself, and if he dares to hang up to the world network, he is looking for death. So nitpicking, either the best or the worst. Otherwise, Bai Yuling would have succeeded at least once or twice.

The eightieth part, after spending more than 30 million contribution points in material fees, Bai Yuling finally refined the most perfect treasure life extension potion in his deduction.

'Rare Life Extension Elixir (6 Stars) is an elixir that stimulates a large amount of vitality and rejuvenates the flesh weight once, and can extend the life of elves for forty-six years. ’

The most perfect is fifty years, but Bai Yuling knows that he can't do it, his pharmacy has only been roughly studied, not even a senior student, and he is 108,000 miles away from the master of pharmacy. If this wasn't a fool's version of the recipe that required superpowers, he wouldn't have been able to refine it at all.

It's okay, the less four years to exchange for vitality treasures almost costs 40 million contribution points, and it is a waste to try again, and he doesn't have many contribution points to exchange.

Seeing that there were only more than 11 million contribution points left in the nearly 40 million contribution points, Bai Yuling could only smile bitterly, asking a doctor of pharmacy to peel off the impurities of the water of youth was only about one million contribution points, but there was no way, the water of youth would die when it saw the light!

Originally, Bai Yuling also planned to exchange for treasures such as sycamore fruits, alas.

'Sycamore Fruit, the place where the legendary Divine Beast Flame Bird has lived for a long time, the precious treasure formed by the power left behind by chance, can improve the elf qualifications, and make up for part of the potential!(Alliance Master Certification!After detailed certification, it has an effect on the king below the third order, and the effect of the fire elves is better) Price, negotiable (don't disturb if you don't have resources worth tens of millions of contribution points!)'

But he remembered that he seemed to have seen this half a year ago, why hasn't anyone exchanged it now, is there something wrong with this sycamore fruit?

Probably not, they have all been certified by the Alliance Master Doctor......

Uh, is it because the grade is too low? The third order of the king is indeed a little low, and the one who can come up with tens of millions of contribution points is either the king of heaven or the old king peak master.

Those who want to exchange can't afford it, but those who want to exchange it don't need it, no wonder it's so embarrassing.

But for his Nine-Tails, it's just right. The potential of the nine tails is missing too much, and the potential potions can't make up for it thoroughly, with this sycamore fruit, it should be able to make up for one or two, but the qualification of the nine tails is a seven-star demon, and the sycamore fruit can't be mentioned.

Well, let's raise the life span of the Rada first.

"Rada, I have completed the original agreement, and you will return to the top soon!"

Bai Yuling let out Lada and said in a low voice.

“......”

Rada's eyes were very moved, and his voice was full of excitement, how long has it been, just a few months, he has gone from being a dying old man ready to go home and wait for death, to the peak of his prime, and the peak power that is almost forgotten is about to recover?

Bai Yuling opened the mouth of the bottle, wrapped it directly with a waveguide to prevent the leakage of vitality, and sent it evenly from Lada's mouth to all parts of the body, so that it was absorbed the fastest.

Rada's body trembled, and he felt it, the power was constantly pouring out, and the dead body seemed to be reactivated, rejuvenated, full of vitality, and tears dripped unconsciously, which were tears of joy.

"Roar!"

The Bloodwing Wyvern appeared on their own, congratulating Radha on his return to the top.

Radha responded happily, intimacy with each other, and collided.

"......"

However, the ten-mile research institute, coupled with the very narrow equipment, a phantom shuttled through this narrow space, and it was three times in the blink of an eye, but it didn't touch anything.

Radha stopped in front of Bai Yuling, and pounced on Bai Yuling gently, his tongue kept licking his face, God knows that Radha hasn't made such a move in hundreds of years, except for his parents, Bai Yuling is the only exception!

Bai Yuling laughed, it was very itchy, he didn't stop Rada's intimacy, and he was also very happy.

After a few seconds, Radha calmed down, and his eyes seemed to change slightly more than before when he looked at Bai Yuling.

Bai Yuling checked Rada's current attributes, and the result surprised him, Radha turned out to be a king-level elf!
