The so-called Dharma Dan of the Protector of the Dao, as the name suggests, is to defend the enemy with the Dan and practice to protect the Dao.

Generally speaking, the Dao Protector Dharma Dan is equivalent to a disposable Dharma weapon. However, it is much more powerful than ordinary magic weapons, and the consumption of its use is far less than the former.

There is no need to charge up in advance, and there is no need to pinch the spell, the user only needs to flick it lightly, and then induce the Dan pattern of the Protector Dharma Dan, which can cause huge damage to the target.

Often, a single Protector Dharma Pill can reverse the situation of the entire fighting scene.

Of course, although it has all kinds of conveniences, correspondingly, its price is also much more expensive than the same level magic weapons and pills.

Not just because of its practicality, but also because of how much it is cherished.

First of all, the Dan Master must not only blend the various medicinal materials together, but also ensure that the activity of the pill is not too stable, and finally, the pill must reach a critical point of balance.

This alone has extremely high requirements for the Dan Master's own level, and it also increases the difficulty of refining the Dao Protector Dharma Dan several times.

Secondly, powerful Dharma pills such as [Flame Frost Polar Pill] not only require the Dan Master to mix the medicinal properties, but also pay more attention to the Dan Master's use of auxiliary drugs to reconcile the conflicting medicinal properties, which is even more difficult. If you are not careful, it is very easy to burst the furnace.

Even, there are some more special existences of the Protector Dharma Dan, which cannot be explained clearly by a single Dan Sutra.

Although the appearance of the Dao Protector Dharma Dan has made the Dan Master's fighting ability much stronger, there are still a small number of Dan Masters who do not recognize the Dao Protector Dharma Dan as an orthodox alchemy method.

And because of the high difficulty of refining and the rarity of the Dharma Dan Fang of the Protector Dao, there has been no news about the Fadan in the inland for many years now—even the Guiyuan Temple in the Eastern District has never shown the Fadan on the bright side.

It was a surprise to be able to get Rin Zhu.

However, not to mention getting the Rin Bead, even if Xuan Yuan gathered all the three extremely cold things of [Rin Bead Dust], [White Stone Cold Qi] and [Frost Moon Clam Bead] at this moment, he would not immediately start refining Guixue Dan, at least he would have to accumulate more alchemy experience.

Xuanyuan picked up the fish and said to the three little guys, "Dinner has arrived." ”

......

......

Two hours later.

After a day of tossing, Xuanwei Xuanming Yuanle was really tired, and squeezed into a stone bed and fell asleep.

Taking off his coat and robe, Xuan Yuan put it on the three little guys.

Lightly coming to the side of the treehouse, Xuanyuan beckoned to the little kingfisher in the bird's nest not far away, and pointed to the bookshelf.

Knowing that, the wings of the little kingfisher flew to the bookshelf, and then with the pecking of the bird's beak, a transparent film disappeared.

Taking advantage of this opportunity, Xuan Yuan took out the only remaining books inside.

Seeing that the goal was achieved, the little kingfisher rubbed Xuanyuan's palm, returned to the nest again, stretched its wings and gently covered the blue egg, closed its little eyes and fell asleep peacefully.

Xuanyuan looked at the appearance of it taking care of its companions, and couldn't help but feel a little touched in his heart.

After a moment of silence, Xuan Yuan picked up the book in his hand and came to the side. The magic trick pinched, a trace of fire ignited in his hand, and with the light of the fire, which was not bright, Xuanyuan flipped through these lost books.

These books don't seem to be some clever chapters, looking at it, the cover of the book is full of some ordinary Taoist book names, what "Qingjing Sutra", "Huangting Exterior Jingjing", "Huangting Interior Jingjing", as well as "Jade Emperor Sutra", "Yushu Sutra", "Dongxuan Lingbao Dingguan Sutra" and so on, all of which are some widely circulated Taoist classic books.

After a cursory scroll for a long time, Xuan Yuan pulled out two books from the pile of books in front of him. One is called "Heart Refining Sword Sutra", and the other is called "List of the Seventh Hidden Veins of Anduguan".

Anduguan, when he first saw this name, Xuanyuan was very surprised.

When I first visited Jirong Mountain, I found a compass in the tomb, which was engraved with the words "Anduguan", but I didn't expect to see these three words again after many days.

Turning over the "Andu Guan Geng Hidden Vein List", a big ranking word came into Xuanyuan's eyes.

"The first generation of hidden vein mountain guards: Huan Xiangming, personal disciples: Puyang Ziqi, Shentu Boyuan"

"The second generation of hidden vein mountain guards: Shentu Boyuan, personal disciples: Jiang Anhe, Mutaihe"

"The third generation of the hidden vein mountain guard: Jiang Anhe, personal disciples: Fu Heyi, Gai Haoxing"

“......”

"The thirty-seventh generation of the hidden vein mountain guard: Min Fengxing, personal disciples: Ji Anyuan, Liu Fuzhi"

Is it the hidden power of the sect, or is it the hidden inheritance of the fire? Geng, the seventh? This sect called Anduguan has more than one hidden vein?

With just a roster, Xuan Yuan really couldn't deduce anything, but that didn't prevent him from making some speculations about it.

Probably many years ago, this so-called seventh hidden vein may have suffered some great calamity by surprise.

All the disciples in the door were killed, forming the white bones in the passage outside the well, and the people stationed in the underground space inside the well seemed to know that it would be difficult to resist the disaster, so they quickly packed up their things and escaped.

Eventually, this relic remained.

However, this ...... It doesn't seem to make sense.

If this seventh hidden vein really encountered a catastrophe, since no one outside was spared, how could the space inside the well be so well preserved?

The gossip square is so obvious that it will certainly not be ignored.

Or did the well illusion work? Probably not.

Although the water well illusion technique is indeed clever, I don't know how many times more clever than the trick of the Rongshan Tomb, but since the other party has the ability to destroy the entire Andu Guan Seventh Hidden Vein, how can the other party be blocked by just one illusion?

The other party definitely has the ability to enter the underground space, however, if nothing else, just talk about this giant tree, it looks like it has not been damaged at all.

Although it had lost its life, its torso branches had been preserved almost intact, undamaged, and showed no signs of fighting.

Whether it's scratches, or corroded chips, or poisoned colors, you can't find them.

Even if the enemy has some strange means to make the giant tree die naturally without resistance, what about the treehouse?

From the very beginning, the treehouse was in order, the flowers in the flower beds were in full bloom, and the frames of the bookshelves were sturdy, without any signs of violent destruction.

The only thing that was a little suspicious was the slightly messy books left on the shelves, which seemed to have been turned over indiscriminately.

However, on second thought, if the people stationed in the underground space at that time escaped, then he would definitely try his best to ensure the inheritance, and it was understandable that he was a little hasty when carrying these books.

Putting down the list, Xuan Yuan pressed his eyebrows.

Removing these unverifiable distractions from his mind, Xuan Yuan picked up the last book and read it.

This is probably some basic method, Xuan Yuan opened the title page a little absently and browsed it casually.

However, as time passed, a flash of surprise suddenly flashed in his eyes.
