River beads belong to the water line material, when refining it, it is better to use yin fire, from the fire in the fire for the yang, the fire for the yin, its image in the sky is the stars listed, in the ground is the light is bright, the fire is soft. The same Xingchen Iron is also the best to quench with Ding Fire, of course, it can also be separated from the fire, but the effect is very different!

Xie Ling valued this black iron heavy sword so much, so he naturally chose to separate the Ding Huo from the fire to temper it, and this time, in addition to the two newly added auxiliary materials, he also took out most of the remaining fine iron and the branches of those camphor trees. The Wind Camphor Tree is the best material for flying away magic weapons, and there are not many materials that can be refined from these picked branches, but they are better than nothing, and it is always a disaster to put it on the body, which just refines it to improve the quality of the black iron heavy sword.

And if the quantity of those refined iron is according to the previous sword weapon standard, at least a dozen mouths can be refined, it can be said that he has invested enough money in order to refine the Black Water Heavy Sword!

The prohibition on the black iron heavy sword was removed, and suddenly it returned to its original rough appearance, Xie Ling slowly rubbed it on the sword body with his hand, and muttered in his mouth: "Black water, black water, this time I have everything, you have to fight for breath!" After speaking, he threw it into the fiery Yuanjia Ding.

It must be quenched first, there are too many impurities in it, and it can be better integrated with other materials to improve the quality after being removed.

In order to get the purest yuan embryo, Xie Ling began to use Ding Huo when refining the black iron heavy sword, the black iron heavy sword first turned red in it, and then slowly began to dissolve into a pool of molten iron, this is not ordinary molten iron, every drop of it is its essence, but some black spots can be clearly seen in the fiery red molten iron, they are uneven in size, and they are very scattered, it is estimated that the original monk who refined this sword weapon is not strong, and he barely tempered the impurities produced by the embryo.

The molten iron rotated rapidly under Xie Ling's control, and the powerful torque separated the impurities inside one by one, and then sent it to the propylene fire on the other side of the furnace to burn to ashes.

This time the refining time was obviously longer than any before, and it wasn't until dawn the next day that the newly refined Black Water Heavy Sword Sword Embryo was completed!

The new sword embryo is more than two feet long, the sword body is broad, and there are faint lines of water and wood stars, which looks simple and heavy, and there is a kind of roundness and fullness in the black.

Xie Ling put the game aside for a long time, and at this time he needed time to rest and recuperate.

At noon, Xie Ling opened his eyes, and the sun shone down from the mist above the valley, and the clear waves of the waterhole under the gentle breeze flashed with crystal light.

He looked at the sword weapon on the stone bed in front of him, and with a flick of his right hand, the sword weapon embryo more than two feet long flipped and rose into the air.

Xie Ling already knew what forbidden Xie Ling was refining, and one after another spells continued to hit the Yuan Embryo and emit a dazzling light.

Unexpectedly, this time he sacrificed two forbidden paths, two forbidden forbidden paths, one mountain ban, and one Kanshui ban.

Why did he make such a change, Xie Ling thought that if the water was so powerful, if the change was slow, it would eventually become a formality, and the power would not be able to be exerted.

That is to say, the water is heavy, but it is still fake if it can't hit the enemy, and the transfer ban is responsible for the rotation in the cloud ban, and the two transfer bans can greatly improve the control of the water potential.

The quality of the Blackwater Heavy Sword has been greatly improved after being re-tempered with the addition of River Beads and a large amount of refined iron. You must know that the river bead is a material that can be refined into a medium-grade magic weapon embryo, and after being added to it as an auxiliary material, even if it cannot directly make the sword weapon reach the middle-grade magic weapon embryo, it is still much stronger than the ordinary low-level magic weapon.

The quality is good, the power of the ban will be enhanced accordingly, and the ban is responsible for changing and carrying in the cloud ban, and it has a very wonderful effect, that is, it multiplies the prohibition of other entities!

Water is a tangible and qualitative object, so it can bless the power of Kanshui Forbidden Water. And the reason why the 'Thunder Fire Electric Light Hammer' that Xie Ling had refined earlier did not use the forbidden was because the thunder and fire were both tangible and insubstantial objects, and the forbidden could not bless them.

In other words, the power of the two water prohibitions and the water prohibitions and the sacrifice of one water prohibition, and one water prohibition and one forbidden, are roughly equal in the power of the water potential.

And the prohibition also has another commendable quality, that is, it not only has a blessing on one prohibition on the magic weapon, but also has a multiplier effect on other prohibitions with the same attributes. The Genshan Forbidden on the Blackwater Heavy Sword can also enjoy the same treatment.

In this way, it is enough to refine a Genshan Forbidden and Kanshui Forbidden as the matrix on the Black Water Heavy Sword, and if you want to increase its power, you can multiply it by refining it.

Therefore, this new Black Water Heavy Sword is actually equivalent to refining three Kanshui Bans and three Genshan Bans at the same time, and its power is at least twice as powerful as the original!

Of course, these are all things that Xie Ling has only recently realized from the 'Forbidden Sea Return'.

The book "Forbidden Sea Returns" mainly introduces the matching skills between the forbidden rooms, which was originally given to him by Lin Dong. But I don't know if the author is deliberately obscure or what's going on, the techniques introduced in it do not list this trait in the forbidden system, but Xie Ling saw that Shangguan Yu's 'Chaotian Aya' was sacrificed in the junior apprentice-level competition of the Refining Academy There are as many as four forbidden realms, so that he can find out after cultivating to the great advancement now.

After Xie Ling's sacrifice was finished, the black water heavy sword in front of him was full of brilliance and restraint, and the sound of flowing water immediately sounded, and a black water held it up and went straight to the top of the waterhole on the opposite side.

The black water is fifteen zhang long and three zhang wide, Xie Ling stepped on the waves, the wind blew his sleeves up, he swept the surrounding mountain walls, and after a long roar, he stepped on the waves and went straight to the clouds!

With his arms stretched, the black water instantly expanded several times, enveloping the surrounding twenty zhang away. The water rippled and glowed darkly.

As soon as Xie Ling waved his hand, the surging black water set off a huge wave three or four feet high, surging forward wave after wave.

As soon as he pressed his hand, the huge waves in front of him stopped, and the back ones accumulated on top of it, and the waves had climbed to a height of twenty feet, and from the bottom to the top, it felt like the building was about to fall!

Boom, the twenty-zhang high black water rushed towards the opposite side like a broken embankment, and it burst out with amazing power at this moment after accumulating!

This is the attack mode after the giant wave is transformed into a flood wave, the huge wave in front is blocked by the opponent, and after accumulating the strength of both sides, it will burst out and give the opponent a fatal blow!

The water was like a rainbow, Xie Ling followed behind, and when the water slowed down, as soon as he closed his hands, the black water swirled and gathered towards the center, forming a huge vortex twenty zhang wide.

The mist above the valley was driven and rotated, nearly a hundred zhang wide, and it looked very impressive!

Xie Ling stepped forward with his hand, and the black water shot out like a thread, and countless water droplets hit the opposite mountain peak like steel balls.

Bang bang bang.

The cliffs outside the mountain peak were knocked down layer by layer, but the water droplets were fierce, and even the bluestone rocks inside were beaten into a sieve, full of holes, and from a distance, it seemed that a grand article was written on it!

Xie Ling grabbed the Black Water Heavy Sword in his hand, and was very satisfied with it now.

Returning to the valley, there are still nineteen days to count, and he is going to use this time to study the prohibition of the huàn well, and cultivate the 'Wind Blade Technique', as for the earth system exercises 'Great Wilderness Technique', 'Earth Splitting Technique', 'Earth Channeling Technique', 'Earth Thorn Technique' and the wood system exercises 'Evergreen Technique', 'Wood Shadow Technique', 'Wooden Stake Technique', etc., can only be left for later.

――――――

In a huge furnace three zhang high in the Dan Courtyard, Yang Zhuo'er wiped the beads of sweat on his head, since he was separated from Xie Ling last time, he was locked inside, and the water and fire tempering his body nine hundred and eighty-one times a day had already made him feel like he was about to collapse!

"Old man, I'm not playing, let me out!" Yang Zhuo'er shouted angrily.

An old man in a yellow robe sitting outside just smiled slightly, and didn't speak no matter how much he shouted.

There are still nineteen days, as long as Yang Zhuo'er can get through it, then this time the Dan Academy will definitely shine in the great competition within the sect!

――――――

Black Tiger Beasts are known for their ferocity among spirit beasts, they have a strong body comparable to that of a demonic beast, and their claws are as tough as a hook, which can easily cut through hard bluestone rocks without damage. Huge but not clumsy, agile as a kitten. At this time, in an underground arena several zhang deep and more than thirty zhang wide, a third-level black tiger beast was staring at the tall boy opposite with cold air.

The young man was shirtless, his two hands outstretched, and he did not shy away from the gaze of this third-level black tiger beast, and there seemed to be a look of expectation revealed from his gaze.

"Ah Bing, remember not to kill it!" said Zheng Bin, the courtyard master standing on it, touching a few small goat's beards.

"Daddy, I see!" the tall boy replied.

"Be careful!"

The third-level black tiger beast pounced when the tall boy turned his head...

―――――――

Ning Chen smashed the giant tripod on his back, although he would do much more than that, he still liked to end the battle in this way.

Xuan Shikai's pupils shrank, and his body was shocked by the powerful force and flew out of the three feet, although he stood firm after falling, he couldn't help but spit out a mouthful of blood in his mouth.

Looking at Ning Chen's back as he withdrew Juding and whistled away, his body trembled slightly, his teeth biting his lips, and his hands clenched tightly.

He has a rare body of ice marrow, and he has an advantage in cultivating ice exercises that others can't match, I thought that except for Jiang Qiao, who has the body of real thunder, others don't have the strength to compete with him at all, but this fierce man Ning Chen, who likes to carry the top and smash people, came out, and attracted the attention of everyone in the Cultivation Academy!

―――――――

There is no time in the mountains, nineteen days have passed in a flash, Xie Ling opened his eyes, although he didn't care about the big competition in the sect as much as before, but as a member of the Refining Academy, he had to fight for honor!

An hour later, the mist over the valley rolled violently, and Xie Ling's black water heavy sword flew out of it, slashing a light and shadow in the void and then disappearing into the sky.

Dabi Zongnai, I'm coming!
