After collecting all the Black Tortoise Demon Blood, Chen Mu carefully inspected the secret vault.

The result was that he did not find any other hidden areas, nor did he find the more precious ‘Black Tortoise Heart Blood.’ However, considering the preciousness of the Black Tortoise Heart Blood, it would be extremely effective for anyone in the Blood Exchange Realm. If there were thirty to fifty Black Tortoises, gathering a large amount of heart blood, it might even be possible to forcibly create a ‘Blood Refinement Perfection’ even when the Blood Exchange Realm system is incomplete.

Of course, this situation is almost impossible, even in the primordial times when demons roamed rampant, there couldn’t be thirty or fifty Black Tortoises, as they were tenth-rank celestial demons, and even more rare in the Recent Ancient Era.

In the past, Ji Hao swept across the world, and it was already extremely lucky to hunt down one Black Tortoise.

After not discovering any other rare items, Chen Mu left the secret vault, waved his sleeve to close the portal, the formation sealed again, locking the remaining demon qi inside, then walked towards the second secret vault.

Buzz.

After opening this secret vault, once again a surge of demon qi greeted him, carrying a rolling pressure that could instantly freeze a Marrow-Cleansing Grandmaster in place, making their hackles stand on end.

As expected, inside the secret vault was again a blood pool, filled with crimson demon blood, gleaming with points of spiritual light.

This time, the aura was rather unfamiliar to Chen Mu, yet he still walked inside with a calm expression, explored the blood pool’s energy a little, and after a brief assessment, roughly understood the origin of this pool of demon blood.

White Tiger!

The demon blood qualified to be placed in these three secret vaults must be tenth-rank celestial demons. According to the Azure Dragon, White Tiger, Vermilion Bird, and Black Tortoise armies, this secret vault should also be one of them.

Although Chen Mu had never seen Azure Dragon Demon Blood, he had swept through a million Azure Dragon Army before, feeling the Azure Dragon’s aura thoroughly, which was completely different from the aura in this blood pool, clearly not of the same type.

As for the Vermilion Bird…

The Vermilion Bird’s nature is of fire, of the blazing kind. In terms of heat, it should surpass the Red Dragon he had slain before, and its blood should be even more radiant than the Red Dragon’s, which was also obviously not the attribute of the demon blood in this pool.

Excluding the Vermilion Bird and Azure Dragon, naturally, only the White Tiger remains.

“White Tiger Demon Blood, huh.”

Chen Mu showed a thoughtful expression and quickly took out the Qiankun Bottle again to continue collecting the White Tiger Demon Blood, then glanced at the Grandmaster Imperial Supervisor beside him, saying, “This demon blood of heavenly demons must have some correlation with the training of the four armies’ soldiers, like the Azure Dragon and White Tiger.”

“Yes.”

The Grandmaster Imperial Supervisor said respectfully, “Although the Imperial Supervisors are not allowed to intervene in military affairs, I do know a little about the training of the four armies’ soldiers. Indeed, they use demon blood to temper their martial bodies, so as to connect and harmonize the blood qi of each person more closely.”

Chen Mu nodded slightly.

He had felt this before when sweeping through the Azure Dragon Army; the soldiers’ auras were interconnected far more closely than the Yu Lin Army of Yu State he had detailed knowledge about.

At the time, he did not pay special attention, merely assuming that the Azure Dragon Army of the Imperial Court was more elite, since even the soldiers were Martial Men of the Bone Tempering Realm. But now it seems it was likely due to the use of demon blood to temper martial bodies.

These White Tiger and Black Tortoise Demon Bloods are indeed fearsome. Tenth-rank demon blood is far beyond what ordinary people can endure, and even Grandmasters who have practiced martial bodies must be extremely cautious when refining even a single drop, as jumping directly into the pool could result in the explosion of their bodies. However, if diluted layer by layer, then there’s not much problem.

By selecting a large number of young people with decent aptitude, starting from skin toughening, using a set of practice methods core to body tempering martial arts with demon blood resources, they practice all the way to the Bone Tempering Realm. Naturally, the auras between them are extremely close, not only fitting the corresponding Azure Dragon, Black Tortoise heavy armor, but also forming a military formation without any sluggishness.

Like that million Azure Dragon Army, although Celestial Masters do not fear them, relying on the perception abilities and extremely high mobility of celestial humans means there’s basically no chance of being surrounded. Even using legendary ‘Qiankun Pot’-like void treasures, they still couldn’t form a military formation to surround, thus they could respond with relative ease.

But if one were truly caught in a million-strong military formation, not only could they charge out with ease, but also sweep across a thousand troops by themselves, slay the commanding general amidst a million troops, and rout the entire army. Under the heavens, that would only be Chen Mu alone!

Hiss.

Soon, the last drop of White Tiger Demon Blood was also fully collected by Chen Mu.

Even though the space inside the Qiankun Bottle was not small, after storing such a large amount of Black Tortoise Demon Blood and White Tiger Demon Blood, it was also more than half full, with not much remaining. There was just barely enough space left to fit another pool like this, but if there were two more pools of such demon blood, there would likely be no space to store them.

After glancing at the space within the Qiankun Bottle, Chen Mu thought for a while without too much hesitation, left the White Tiger secret vault, and directly walked towards the third secret vault at the end. When he pushed open the secret vault, inside it was suddenly clear, revealing another heavenly demon blood pool.

This time, the blood pool’s aura was very familiar, recognizable at a glance.

Azure Dragon Demon Blood.

Chen Mu stood with hands behind his back next to the Azure Dragon Blood Pool, his gaze sweeping across the surroundings, seeing that indeed the entire secret vault only contained this Azure Dragon Demon Blood, he said, “Rumor has it that the Vermilion Bird Army is the weakest unit among the four armies, and now it seems there is indeed a reason for it. Perhaps the foundation of the Vermilion Bird Army was not forged from Vermilion Bird Demon Blood.”
