This incense can be used to comprehend the Dao or to consolidate one's martial arts cultivation.

After reaching the Divine Martial Realm, most pills no longer help with cultivation, which shows how precious this incense is.

It's no exaggeration to say that if you can obtain a piece of dragon brain incense when trying to break through to the third rank, your chances of success will increase by 10% or 20%.

After sending the message back, Yin Zhe specifically checked the records of the imperial court regarding camphor.

Only century-old Ruoba trees produce the best quality products, and those that can produce "cooked brain" are extremely rare.

The yield is extremely low; even the best tree can only produce a few ounces a year.

The resin seeps out naturally from the cracks or insect holes in the trunk of the borneol tree, and slowly crystallizes over a long period of time on the surface of the bark or in the internal crevices, forming translucent, ice-like and jade-like crystals.

It must be formed naturally; the best quality is white as snow and pure in texture, which is called "ripe brain".

Other methods have been tried to increase production.

For example, make incisions in the tree trunk to allow the resin to solidify.

However, the quality of crystals obtained in this way is far inferior to that of mature brain, and is called raw brain.

Its color is yellowish or brownish, its texture is impure, its aroma is rather dull and carries an impurity scent, and its effectiveness in aiding cultivation is far inferior.

And what's in the box in front of me are truly authentic brains.

Moreover, the quantity is enormous.

Yin Zhe didn't dare to use his hands to pry it up, but with a little sense, he could roughly tell that it was about the amount that had been presented to the palace as tribute for three or four years.

Despite being confined by the military, mining, processing, and transportation were subject to extremely strict controls.

It should be sent directly to the palace, and only His Majesty can use it. Apart from a small portion being used for rewards, it should never be leaked to outsiders.

And yet, we suddenly saw such a huge number here!

Yin Zhe slowly exhaled a breath of stale air and turned to look at the head of the God of Wealth.

"Nine Gates, what impressive methods..."
