Beiyu changed a set of clothes and left the Fighting Soul Field, and now it was almost morning, although he had experienced so many days in the Fighting Soul, but in the outside world, it was only a night.

After Beiyu made sure that he was not followed, he first went to the mercenary union to let Eighty-one disguise himself, because now many people who block their faces will be suspected of being mercenaries Ren Pingsheng, Beiyu has no way, in order to conceal himself, let Eighty-one disguise himself into the appearance of a middle-aged man, ordinary, and you can't find that kind in the crowd.

Then, Beiyu came to Tang Baohui, bought some alchemy materials, and rented a practice room.

The materials for alchemy were bought to try the alchemy alchemy technique passed down to him by the black phoenix, and at the same time to refine a few spirit pills to prepare for the repair of the Wuxian Martial Force, and the practice room was naturally used for alchemy and the repair of the Martial Commander's Table.

Preparing everything properly, Beiyu entered his own practice room, Beiyu rented the best practice room, fifty taels an hour, and it was extremely wide, whether it was alchemy or refining, all kinds of equipment were available, even if the soul would be summoned, it would not be crowded.

......

Beiyu also inquired about Tang Xueqing's whereabouts, but learned that she had set off for Kua Sea after negotiating a task for herself.

Beiyu admired in his heart, this president is worthy of being the president, he is rigorous and meticulous, and he will not waste any time.

Anyway, I'm not in a hurry, there are still three months to go, from Pingdu City to Kuahai, if you don't move the big array, you have to pass through two cities on the way, it will take about a month, so Beiyu is not in a hurry, and it is the key to improve your strength first.

After all, the inheritance secret land is restricted to the three realm generals, although they are the second realm to meet the requirements, but the stronger the better the chances of winning, Beiyu will naturally not be sloppy, and strive to improve his strength to the Bifu realm in these days, and promote the three realm generals.

Beiyu concentrated and stared at the Dan furnace in front of him.

Alchemy has three determinations, hand determination, eye determination, and heart determination.

It is necessary to grasp the heat of alchemy and the mastery of medicinal properties at all times, and these must not be left behind.

Fortunately, Beiyu learned alchemy refining tools when he was young, and he is quite proficient in mastering the medicinal properties of various materials, and there are also many medicinal properties recorded in the alchemy secret record of the black phoenix inheritance, so Beiyu dares to alchemy.

Otherwise, once there is a slight mistake, the Dan furnace will explode, and the injury will be secondary, and Tang Baohui's things will be a bit of a loss if they have to lose money.

Beiyu concentrated on the alchemy, and the black phoenix was guiding on the side.

At this time, this seemingly useless fat bird is still somewhat useful.

"Put the breath-holding grass, let it go, alas, it's two breaths slower, stir and stir, right..... Quick, heat up, oops, why are you so stupid. ”

The black phoenix reprimanded Beiyu while instructing, hating iron and steel, and from time to time he slapped Beiyu's face with his wings.

Bei Yu knew in his heart that he was doing it on purpose, but he remained silent, listening to the guidance of the black phoenix while slowly improving.

Finally, after consuming more than twenty more materials, Beiyu was finally able to skillfully practice the Gathering Spirit Pill of the Lower Nine Grades.

Like the magic weapon of the weapon, the elixir generally has nine grades in the upper, middle and lower parts, and the elixir at each stage is judged according to the color, fragrance, and effect of the elixir.

Although the taste of the elixir of the lower nine grades refined by the Northern Imperial is a little mushy, and it looks a little dark, the effect is real, so the black phoenix sets it as the elixir of the lower nine grades.

Two hours have passed since this toss.

After refining five lower ninth-grade black elixirs, Beiyu finally refined a pale golden elixir with a faint medicinal fragrance and a light black elixir that didn't look too black.

During this period, the furnace was fried three times, but fortunately, the furnace was hard enough and not damaged, but only a few medicinal materials were lost.

This made Beiyu secretly call out that luck was bursting, if the furnace really blew up the furnace, the money to lose the furnace could buy nearly thirty medicinal materials!

So Beiyu continued to start the crazy alchemy, and after another two hours, he was able to skillfully practice the eight-grade Gathering Spirit Pill.

As for the lower seventh grade, Beiyu still doesn't want to think about it for the time being, this difficulty is no less than the eighth grade is more than one level higher, so why the alchemist is noble is because the pill is difficult to refine.

Beiyu practiced for four hours, and he was able to master the refining of the eight grades of pills, and he was very satisfied, and after refining five more, he began to stop.

Alchemy requires not only a mastery of medicinal properties, but also a strong mental power and the ability to concentrate on the spirit.

Beiyu continued to refine for four hours, his spirit was exhausted, and after looking at the ten lower ninth grade black spirit pills and six ordinary lower eighth grade spirit pills in his hand, he smiled with satisfaction.

Beiyu thought that his spiritual power was not bad, and after using the second form of the Sun Stepping Sword Song in the Fighting Soul Field, his spiritual power was evacuated, and the consumption was extremely great, and when he recovered, it was far better than before.

But the alchemy can only last for four hours, but it is still an extremely low-level pill, which makes Beiyu sigh a pity.

The black phoenix mercilessly mended the knife on the side and said, "Well, it only takes four hours to be able to refine the eighth-grade elixir, although it is still a little worse than me at the beginning, but it is enough to show that you are talented." ”

But in his heart, he muttered: This stinky boy is really a person? Alchemy can master the alchemy method of the eight-pin pill in four hours, and he can also practice the excellent and mellow medicinal fragrance of the restrained and unoverflowing elixir, if he just started learning, I don't believe it!

Even when the black phoenix was alchemy, it took a whole day to master the alchemy method of the lower nine grades, and as for the eighth grade, it took three days and three nights to refine without sleep before he could barely master it, and this kid was only four hours, isn't this a blow to the bird.

When Beiyu heard Heihuang say this, his heart was slightly happy, "So, my alchemy speed is not bad?"

Black Phoenix smiled and said, "Not bad, yes, barely first-class." ”

But he said in his heart: This is not only damn good, I don't know how many miles away those so-called alchemy geniuses have fallen, four hours, I'm afraid that the entire Jiangyuan Star will not be able to find ten.

Beiyu was even more happy, looked at the pill in his hand, and nodded vigorously, "Since the Gathering Spirit Pill is available, then let's start saving Wu Lonely." ”

The black phoenix nodded and retreated into the distance.

The rest of the things have nothing to do with him, he is a demon clan, and he doesn't understand the martial arts of the human race, such as the soul of the military general, etc., so he can only stare dryly at this time.

Beiyu sat cross-legged and held a spirit pill in his mouth, but he didn't bite it, and he wouldn't swallow it until his spiritual power was exhausted.

Immediately afterwards, the Northern Imperial General was surrounded by three-grade demon stones, holding two fifth-grade demon stones in his hands.

Silent injuries require a lot of energy to repair, otherwise it is absolutely impossible to recover to the peak even with the shotai cone.

With everything ready, Bei Yu felt that his spiritual strength had almost recovered, and his mind moved, and a pitch-black stone platform emitting blood-colored light appeared nine inches above his head.

The silent military commander's platform!
