Starting with Hundred of Millions of Guardian Spirits

"It's too dark..."

"This fellow Yuanshi Laoer..."

Lingbao Tianzun frowned tightly and murmured, but his footsteps could no longer move forward.

In their sight, under the dim light, there are long rows of cages on both sides.

Yes, it is the cage.

A cage like a kennel.

In these cages, either curled up or sitting with disheveled creatures.

There are people, monsters, and even some illusory souls...

With the appearance of Xia Yan and Lingbao Tianzun, the people in the cage raised their heads mechanically. The expressions on their faces were numb, seemingly demented, and they made a babble, and they couldn’t even speak a word. ...

Xia Yan walked forward along the corridor in silence. The creatures in the cages on both sides looked strange, and many shocking strange creatures could always be seen.

The human with three heads and six arms, or a few bodies, or all kinds of arms all over the body...

This, this is like a strange research institute that can only be seen in film and television dramas and novels.

"Hey, this is a human. I can see that this little girl with all kinds of arms was originally a human..." Lingbao Tianzun said with an ugly expression.

Xia Yan nodded.

In fact, the two had guessed something.

This hidden underground space in Yuxu Palace is not a treasure house of rare and exotic treasures, but a hidden area similar to a modern research institute...

It's just that in today's era, even the most advanced research institutes dare not use creatures with advanced intelligence to do research.

But in the world of immortals, what is the higher spiritual wisdom?

This kind of thing that violates the ethics and morals of the world, in the eyes of some powerful immortals, is just a little help on the way to become stronger and gain more strength.

Xia Yan did not judge Yuanshi Tianzun's practices.

He had never thought about it that way.

Going deep along the corridor, the vision suddenly opened up, and finally a huge space appeared in front of Lingbao Tianzun and Xia Yan.

People haven't stepped in yet, but they can already smell the rich blood inside.

As far as I can see, there is a huge blood pool in the huge underground space.

Scarlet blood was flowing in the pool, and the blood flow seemed to be boiling, steaming, agitating, and tossing, and occasionally a few strange-looking corpses rolled over the blood pool, giving people a glimpse.

"Hiss~"

"There is a corpse of an ancient true dragon in this learning pond?! Wait, then, is that phoenix?"

Lingbao Tianzun was extremely shocked, his eyes widened, and his face suddenly became extremely weird, and he whispered: "In order to restore the realm of cultivation, the old man is here to refine the blood of all living beings? Is it possible that he wants to condense Come out a blood pill that is the source of all beings?"

"Blood Origin Pill?" Xia Yan glanced at Lingbao Tianzun. He was absolutely not qualified to know these things in his previous life, and he had never heard of the blood source pill.

Lingbao Tianzun suddenly became solemn and nodded slightly, "Yes, it is the Blood Origin Pill."

w

"This blood source pill is extremely rare. If you want to refine it, you need to collect the blood of sentient beings. You must know that within the thirty-sixth level of the six realms, there are many kinds of all living beings, although no one can find where the sixth realm is. , But there are countless races in the Thirty-Five Unbounded Heaven alone."

"If you want to refine a blood source pill, you have to collect at least half of these strange races."

"There is still a lot of rare and strange races, which ordinary people can do."

"Of course, this sword is not a question of whether it can be done or not. Whether it is in ancient times or in the current era, anyone who dares to give birth to the idea of ​​refining the blood source pill is the common enemy of all races..."

"The old man Yuanshi dare to do this, I never expected it." Lingbao Tianzun smiled bitterly.

Xia Yan squinted his eyes. It sounded horrible. A pill requires the blood of sentient beings to be refined. This action is tantamount to declaring war on the whole world, because no matter which race it is, everyone will worry about one day. The people of the tribe were arrested for alchemy.

"what?!"

"Wait, this old immortal has been refined?!"

Lingbao Tianzun suddenly flew towards somewhere in the blood pond. He waved his hand, and suddenly three **** pill flew out of the blood pond, which was like a magnificent ruby-like strange pill.

"Three blood source pills..."

Lingbao Tianzun secretly smacked his tongue.

He still underestimated Yuanshi Tianzun. Although in this era, Yuxu Palace had a short time to recover, but within this short period of time, Yuxu Palace had secretly collected the blood of many creatures.

"What is the effect of eating this thing."

Xia Yan's voice suddenly came.

When Lingbao Tianzun heard this, he almost fell into the blood pool from mid-air with fright. He suddenly looked at Xia Yan and said with a shocked expression: "Little, little friend, you, you want to eat blood source pill?!"

Xia Yan nodded blankly.

Really want to eat? !

Lingbao Tianzun was completely shocked.

This refining blood source pill is already shocking enough, how dare ordinary people eat it again, it is against the heavens.

But he didn't know that there would be a catastrophe in the near future.

Since he could become stronger, Xia Yan had no reason to refuse. In his previous life, he was arguing for life among the dead, and when it came to his cruel temperament, Xia Yan was much stronger than those who were born to be superior.

He didn't feel that there was anything wrong with becoming stronger. Even if there was a mistake, it would be better than one day in the future, when a disaster strikes, he can only look at his beloved tragically and helplessly, and the one he cares about will die.

The next moment, Lingbao Tianzun flew back to Xia Yan's side, and after secretly swallowing his saliva, he whispered to remind: "If you want to eat this blood source pill, the soul must be strong, and it is best to have a sage like me. Soul and spirit."

"Furthermore, this pill is against the heavens and shouldn't exist. Swallowing it is likely to invite a catastrophe. Although it can make your cultivation realm progress by leaps and bounds, if you are killed by the catastrophe, you will lose more than you gain. Up."

Xia Yan nodded, but did not hesitate, and reached out to take the three blood source pill from Lingbao Tianzun, and swallowed it on the spot without hesitation.

Really, really ate...

Lingbao Tianzun's cheek twitched a few times, and he suddenly understood why Xia Yan could be called an anomaly in this era.

This person's xinxing is very human, and others may have to hesitate, but he has no volatility and doesn't care at all...

After the three blood source pills entered his abdomen, Xia Yan only felt a warm current fill his body immediately, as if a fire exploded in his belly.

If it weren't for his amazing Taoism, the strength of his consciousness and soul was far beyond ordinary people, and just swallowing this blood source pill would likely be killed on the spot.

At the same time, the outside world suddenly changed dramatically...
