In other words, there is no more Ou Tiangong in the world, and I am afraid there will be no such a clever swordsmith again.

Just like Chu Feng's Immortal Danzun, he was definitely the pinnacle among the Danzun at that time. After he died, there was no one in the world who could refine the elixir of immortality.

Sacrifice your life just to forge a sword that can suppress demons. The noble character of this Master Ou is really admirable.

Chu Feng asked himself, if he were to sacrifice himself for the benefit of people who had nothing to do with him, he would definitely not be that great.

Of course, it is not excluded that Master Ou sacrificed himself to forge a sword, and there is an unknown secret in it.

For example, one of Master Ou's close relatives was killed by the demon. Or maybe his relatives are seriously threatened by demons. If the demon is not removed, all his relatives will be killed.

"Master, you continue to inquire about the news of the sword mound, and as soon as there is a major movement or change, notify me immediately. In addition, keep a close eye on the Sword Cloud Prince, and I must take back the Jiuyang Sword Vein before he advances to the Sword Saint. ”

Chu Feng's starry eyes revealed a cold murderous intent.

Master Li had never seen such a sharp side of her master, and a hint of brilliance flashed in her beautiful eyes.

On weekdays, in her impression, Chu Feng is low-key and introverted, scheming. It's not like a teenager, but like an old monster who has lived for thousands of years, is wise, calm-hearted, and ruthless.

At this moment, Chu Feng showed a hint of a young man's sharpness and flamboyance, and for the first time, Master Li realized that his master was still a teenager.

It was only because he was so good that Master Li subconsciously regarded Chu Feng as an old man.

"Master rest assured, I promise that even the deepest secret of Prince Jianyun will be dug out!" Master Li also knew Chu Feng's life experience and was full of admiration for his master. He is full of hatred for the Prince of Jianyun who snatched the master's sword vein.

She was very happy to see Chu Feng take the sword vein back.

......

Since Chu Feng planned to go to the Sword Shrine to take an adventure and compete for the sword that was about to be born, he naturally had to make some preparations.

Fu Dan is powerful and can directly improve his strength.

The usage is also very simple.

The most important point is that refining Fu Dan is Chu Feng's old business. This is also his strong point.

"This time to compete for the peerless sword in that sword mound, there must be countless strong people involved. I'm definitely at the bottom. It can no longer be limited to the Golden Rune Pill, and some other Rune Pills must be properly refined. ”

There are many types of runes, in addition to the regular five-element runes, there are also wind and thunder, two kinds of runes.

Other Dan masters, who can refine the Five Elements Fu Dan, are already very powerful.

And Chu Feng, no matter what type of rune pill it is, can be refined.

Of course, Fu Dan is also divided into grades.

The higher the grade of Fu Dan, the more powerful it is.

For example, the first-grade Yan Explosion Pill refined by Chu Feng could directly kill a master at the level of a sword master. Even the Great Sword Master can hurt.

The second-grade Golden Rune Pill he refined could completely beat the level of a great sword master.

Even kill the big swordsman who is a little rubbish in seconds.

"Refining Fu Dan requires extremely high spirits and spirits. With my current strength, I can only refine second-grade rune pills at most. "Chu Feng is currently in the realm of a sword master, and there is no problem refining the second-grade Fu Dan.

If you refine the three-grade rune pill, I'm afraid it will be like a catastrophe.

It's tough.

"The cost of refining a first-grade rune pill is extremely low. Refining a second-grade rune pill increases the cost by at least ten times. With the remaining silver taels on my body, I'm afraid it's only enough to refine five or six second-grade rune pills. That's not enough!"

Chu Feng calculated that he would have to refine at least a hundred second-grade rune pills.

If he had enough time, he was ready to try to refine a three-grade rune pill.

If it can really be successfully refined, it will be equivalent to having a nuclear bomb on your body. Because of the three-grade Fu Dan, he can beat the master of the Sword Saint level.

Chu Feng used the sword master cultivation as a cover, and suddenly cast the three-grade rune pill to attack the master of the sword saint level. The odds of success are extremely high.

Imagine, if a mosquito kills a male lion, will the other party be prepared?

It must be careless and insignificant. Mosquitoes will never be taken into account.

The three-grade rune pill is so powerful, and its price is also extremely terrifying.

The cost of materials for refining it alone is as high as more than 30,000 taels of silver.

Don't think that 30,000 taels of silver doesn't seem to be a lot, this estimate is just the cost of a furnace of materials. In the actual refining process, even a Danwang-level master was not sure that he would succeed in refining at one time.

Under normal circumstances, King Dan refining the three-grade rune pill has a success rate of about one-tenth.

That is to say, a Dan master at the level of King Dan can only become a furnace of Dan if he refines ten furnaces of three-grade Fu Dan.

It's not a 100% guarantee that ten furnaces can become one furnace.

Some are unlucky, or the Dan King who is not skilled at home, or refining the three-grade rune pill that he is not familiar with. This Cheng Dan rate may be lower, 1 in 20, 1 in 30......

There is only an upper limit, no lower limit.

It can definitely be outrageously low.

This is also why it is difficult to buy more than one grade of Fu Dan on the market. Because the cost is too high, the profit is almost zero. It is even possible to lose money.

Who wants to make a loss-making deal?

Chu Feng calculated for a moment and refined a hundred second-grade rune pills, which was equivalent to the appearance of thirty furnaces. Coupled with the material cost of a furnace of three-grade Fu Dan, it is estimated that it will cost about 100,000 taels of silver.

The last time I refined the Pseudo Pulse Pill, I had already received full support from Shizun, Senior Brother and others. Naturally, it's not good to go to them again this time to ask for it.

After all, they also need to cultivate themselves, and they must consume a lot of resources. Coupled with other expenses, the last time I was able to exchange a 10,000-year-old Great Luo Sword Grass for Chu Feng, this was already a great favor.

"Where can I go to find 100,000 taels of silver in a short time?"

Chu Feng frowned, thinking hard about how to get money.

It's a pity that this place is far away from the royal capital of the Jianyun Dynasty. Otherwise, you can take 100,000 taels of silver from Bloodbeard for emergencies.

"Have you heard? There is a sword in the sword mound in the Demon Suppression Mountain Range, and it seems that many strong people of the sect are ready to go and grab the treasure. Alas, if it weren't for the fact that I only had the strength of an intermediate swordsman, I would definitely try my luck. ”

"Wealth and danger, you don't go, I'll go! As long as you get an ancient sword, Lao Tzu will be developed! Damn, last time Ji Yuanba, that bastard, robbed my girlfriend. If you get the ancient sword, Lao Tzu will be the first to kill him!"

......

Unexpectedly, there was news of the birth of a peerless sword in the sword mound, and it spread extremely quickly.

Chu Feng walked in the sect, and he could hear the heated discussions of the sect's disciples at any time. It's all about the sword shrine.

"Hey, Senior Brother Chu, what are you thinking, even walking is so engrossed!" A sweet and pleasant voice sounded behind him, and a soft jade hand slapped on Chu Feng's shoulder.

The fragrant wind also hits the nose with it.
