As one of the many treasures, the effect of pecan yellow heart fruit is naturally extraordinary.

The Yuanli Essence that has been nurtured for more than two hundred years, even if Xuanyuan is good at absorbing and storing the Northern Darkness Qi Technique, he still feels a little unbearable.

The essence is constantly replenished, and it is continuously converted into mana.

In the end, I don't know how long it took, the Bigen Yellow Heart Fruit finally turned into an ordinary shriveled fruit, and the Yuanli Essence in it was completely wiped out by Xuan Yuanshi.

After a long sigh of relief, feeling the abundant mana in his body, Xuanyuan's face was not shocked, and he began to build the Dao Law Qi vein.

The mind precipitated, and the circulating mana gradually diverted to the limbs and hundreds of bones of the body under the control of Xuanyuan's CAO. At first, it is the same width as the meridians, it becomes as thick as a hair, then it is as thin as a hair, and finally it is difficult to detect.

It is like a seed that grows strongly, slowly stretching out the foundation on which it depends, connecting to all parts of the body. In the end, silently, after Xuan Yuan spread the mana veins to the various trunks of his body, he finally completed the breakthrough of the first realm.

If Xuanyuan's mana level before the breakthrough was a narrow well, then the mana level after the breakthrough could be called a clear spring with abundant water.

The reason, in addition to the most important pecan yellow heart fruit, has a lot to do with the original owner's careful polishing of the body for 20 years.

Moreover, because the mana was immersed in the limbs, the body gradually became stronger under its nourishment and strengthening. Although it has not yet reached the level of not being afraid of bullets and artillery, it is indeed possible to ignore ordinary swords and swords.

"Ding-Congratulations to the host for being promoted to a heavy realm, and a reward will be issued: choose one of the four arts gift packs, please choose by yourself"

Xuan Yuan was slightly stunned, how long has it been since the system had this kind of welfare reward? It seems like a guide task issued a month or two ago, right?

"Danshu!" Without hesitation, Xuanyuan chose Danshu among the four arts of the Dan Weapon Rune Array.

Whether it is making weapons, arranging arrays, or drawing talismans, they are all choices that can enhance the Xuanyuan Fighting Method in a short time.

However, after this breakthrough, Xuan Yuan found that if he had already reached the current level of mana, would he still need to spend time trying to lure the young man out and finally defeat him? Obviously, he only needed to release a few more combined attack spells, and the young man would naturally be left and right.

And the Danshu is the most effective means of the four arts to accelerate the growth of cultivation.

As his mind made up his mind, a Dan furnace no bigger than a palm floated in front of Xuan Yuan. At the same time, a streamer of light appeared out of thin air and merged into Xuanyuan's eyebrows, and a large amount of information was transmitted into his mind.

In just an instant, Xuan Yuan knew what kind of reward he had received - "Nantai Jade Miao Dan Sutra".

The alchemy techniques and various precautions were elaborated in detail, and at the same time, a large amount of knowledge of plant and tree identification flashed in Xuanyuan's mind one by one.

From the basic ginseng, angelica, wolfberry, and yellow essence, to the deeper Juling grass, Huiqi Hailan, Bi Qingzhu, and even the habits of more cold plants and trees such as Qimu leaves, Bagpihua, and lavender, they were all digested by Xuanyuan one by one.

At the same time, there are a total of seven kinds of Dan prescriptions scattered on the Dan Sutra. The Shengsheng Pill and Citigroup Powder used in the Tibetan Qi Realm, and the Meditation Scatter and Divine Pills used in the First Heavy Realm......

Xuanyuan opened his eyes, digested the "Nantai Jade Miao Dan Sutra", and looked at the half-human-tall Dan furnace in front of him. The Danlu is purple, with a small mouth and a large belly, and four toads with their tongues are engraved on the surface, and on the tip of the toad's tongue, there seems to be a cluster of jumping flames.

【Purple Clam Furnace】Ingest four flame clam essences and seal them in copper, which can drive them to spit out purple fire and refine elixirs when used.

is a very concise description, but Xuanyuan knows the value of it. Refining the Dan Furnace has always been an extremely complex project, not only considering its tolerance to the high temperature of Dao Fire, but also considering the efficiency of its refining spiritual power.

Even, some refining tools can also improve the rate of becoming a pill through the cooperation of various magic array runes, and can refine the pill - this is the case with the [Purple Clam Furnace] in front of Xuanyuan.

Why do you always give yourself problems? The half-human-high Dan furnace has to be tossed again if you want to bring it back to the Qing microcosm.

Walking forward, with both hands, the Dan furnace, which didn't seem to be huge, but actually had hundreds of catties, was easily lifted by Xuanyuan. Step by step, Xuan Yuan walked out of the tomb with it.

Out of the tomb door, the black and white coffin was still lying quietly. Xuan Yuan frowned, put down the Dan furnace, and approached to check.

Before, after a big battle with the youth, Xuanyuan's state was really not good. Rather than venture into this strange coffin, it was thought that it would be better to explore the burial chamber first. When you are in good shape, it's not too late to dispose of this coffin.

And now, he has not only recovered his mana, but even his power has reached a higher level, so naturally he will not ignore the black and white coffin again.

The fingers touched the coffin itself, and the mana slowly penetrated. Unexpectedly, a cold air film bounced it back, and the mana that bounced back even brought a dark aura.

Xuan Yuan frowned, the thunder light swam, dispelling this breath, a trace of uncertainty flashed in his eyes, staring at the coffin.

In the middle of the night, Xuan Yuan suddenly picked up the palm thunder and quickly slashed towards the coffin. The coffin's reaction was even more intense, the lid of the coffin shook violently, and there were bursts of murmuring.

"Blood. ”

"Sacrifice. ”

"Flesh and blood. ”

"Strength. ”

"Nourishing. ”

"The living die, the dead live. ”

The coffin took advantage of the momentum and pounced, as if a huge mouth was about to swallow Xuanyuan whole.

Xuan Yuan listened to the small sound in his ears, but he was not affected in any way. Watching the coffin pounce up, a palm thunder imprinted.

As if a terrible scream was heard, the coffin stopped. However, Xuan Yuan was also affected by the coffin's huge body, and even though his body had been amplified, he still couldn't stop taking two steps back.

Its original black and white, rather mysterious appearance, has become a little ......

The bottom half of the coffin remained the same, but the lid was a shabby, shabby wooden lid with large purple-black spots covering it, making it look like it was stained with large stains.

Xuanyuan saw sharply that at the very edge of the coffin lid, there seemed to be a piece of gold paint the size of a fingernail.

The lid of the coffin seemed to see that the situation was not good, and a large amount of yin qi suddenly erupted, and it actually spun around and flew out of the stone wall, and disappeared in a blink of an eye.

The speed was so fast that even Xuan Yuan didn't react.

This..... What the hell is this! The coffin is fine? It's not impossible, but, judging by its behavior and intelligence, how can it only do this!

According to the strength and status of the young man, he would never be eligible for such an item. Xuan Yuan frowned, took out the young man's package, and carefully examined the clues.
