Xia Sheng's idea was good, he hoped to use the corpses of those three emperor-level spirit beasts to refine a toxin of a higher grade than Dizang Ling, but when he actually implemented it, he found that things were not as simple as he expected.

The first is that there is not enough time.

Cheng Liran was already dead, and the spiritual aperture in his body had already collapsed, whether it was the Northern Stygian Cold Scorpion, or the Two-Headed Stone Python, or the Purple Bone Bee, they were all in the process of rapid annihilation.

I'm afraid that before Xia Sheng can finish extracting the toxins inside, these three-headed spirit beasts will completely disappear from the world.

Xia Sheng estimated slightly, even if he exerted the fastest speed, he could only refine the toxins in the body of a spirit beast at most.

So, which one to choose?

In addition, there is a second question, what container does Xia Sheng use to preserve these refined toxins?

Judging from the toxicity of these three-headed spirit beasts, I am afraid that even Tianxuan porcelain will be corroded and dissolved, not to mention that now in Xia Sheng's hands, there is not even the most ordinary porcelain bottle.

Things got a little tricky from the start.

However, these two seemingly thorny problems, as long as Xia Sheng is willing to sacrifice the Underworld Banner, everything will be solved.

It is true that before this, in the first eight lives of Yu Xia Sheng, he had never seen this black Ling Banner, but if he hadn't seen it, it didn't mean that he didn't know what this spiritual object was for.

After all, Xia Sheng was very familiar with the dead aura above the Stygian Banner.

As early as when he became a barbarian wizard in his sixth life, he had been exposed to such power, not to mention, later in the depths of his soul, a black power seed appeared.

The spring water that comes out is similar to this Evil Flag!

The difference is that there is no way for Xia Sheng to carry the spring water, because without the erosion of the power seed, it will become an ordinary mountain spring again.

But this Underworld Banner can become Xia Sheng's spiritual weapon!

At this moment, the Underworld Banner had been completely integrated into Xia Sheng's spiritual aura, and it was difficult to distinguish between them, so Xia Sheng knew better what kind of terrifying power was contained in this seemingly ordinary and ordinary Command Banner.

One of the very important things is to be able to swallow up all negative energy.

Concrete things such as toxins, carrion, and blood, as well as ethereal negative emotions such as fear, despair, and hatred, can become nourishment and make them stronger!

Of course, the current Underworld Banner is only a scholar-level spiritual weapon, and to what extent it can be achieved, Xia Sheng still doesn't know, but judging from the information he has obtained, he can already be sure that in the future, this Underworld Banner will definitely grow into a more terrifying existence than Poor Sang!

Don't forget, Devour is just one of the features of the Stygian Banner!

Therefore, if Xia Sheng was willing to release the Stygian Flag, I am afraid that in less than half a pillar of incense, it would be able to gnaw the three poisonous beasts cleanly.

But he couldn't, at least not yet.

Because after the Demonic Banner was stationed in the Spirit Aperture, he could already clearly feel that the two forces in his body were gradually unbalanced.

On the one hand, there is the life force from the poor mulberry, and on the other hand, the destruction from the Grim Banner.

As a division-level tree of life, Poor Sang was completely suppressed by the scholar-level Evil Banner!

If the Demonic Banner is allowed to absorb toxins and evolve into the Master Spirit, I am afraid that the entire Poor Mulberry Hall will collapse at that time!

As a spiritual cultivator, Xia Sheng should have been cautious when choosing a fusion spirit object, because there are too many factors to consider, including the fit and cooperation of various spirit beasts and spirit weapons, as well as their evolutionary selection and fusion direction.

For example, Cheng Liran, the three-headed spirit beasts in his body are all highly poisonous, which can not only strengthen his control over toxins, but also make the three-headed spirit beasts appear more tacit in the attack, producing complementary and mutual assistance.

Generally speaking, it is rare for a spiritual cultivator to choose two spiritual objects of opposite elements to reside in the spiritual aperture together, because that will be very dangerous, and if he is not careful, it will lead to the collapse of the spiritual aperture and the consequences of his cultivation being completely scattered.

For example, Qin Yan, when he already had a green bird, he would never choose a water-attribute spirit beast when he was promoted to spirit general!

But now Xia Sheng just did it.

He incorporated both the powers of life and destruction into his aperture, as if he didn't care that the collision of the two energies would destroy his aperture to pieces.

This is no longer something that can be summed up by the audacity of an artist, but a joke with his own life.

At this time, he is like dancing on the tip of a knife, and if he is not careful, he will never recover!

But since Xia Sheng dared to do this, it meant that he was absolutely sure that he could find a space to balance the power of the two.

After all, the same thing he had already done in his previous life.

It's just that at that time, what he fused was the power of darkness and light.

Therefore, at this moment, Xia Sheng didn't dare to let the Stygian Banner grow further by devouring poisons, he could only use his own way to extract toxins.

But which spirit beast to choose?

However, in the blink of an eye, Xia Sheng had already made his choice, he gave up the purple bone bee that could kill Huai'an with one blow, and did not care about the two-headed stone python that seemed to be both offensive and defensive, but walked straight towards the meat hook that was cut off by the Northern Stygian Cold Scorpion.

Because the Northern Stygian Cold Scorpion is a very special spirit beast, in addition to the poison hidden in the scorpion tail, in its cranial cavity, there is also an extremely precious Heavenly Cold Pearl!

It's a pity that in the previous attack, Cheng Liran was first caught off guard, and then he was frightened because of Huai'an's sudden appearance, so he was not able to exert all the power of the Northern Stygian Cold Scorpion.

If Xia Sheng was the only one, I'm afraid that even if he hadn't been poisoned, he would have been frozen into ice slag a long time ago.

Although the Northern Stygian Cold Scorpion was inferior to the Purple Bone Bee in terms of toxicity alone, Xia Sheng was able to obtain two enemy weapons from it after all, which could be regarded as a surefire deal.

And the most important thing is that Xia Sheng can configure the corresponding antidote according to the venom of the Northern Stygian Cold Scorpion.

Don't forget, there is still cold poison in his calves!

Now the only question becomes what kind of container should be used for storage.

Seeing that the time was passing minute by minute, Xia Sheng never thought of a solution, so he could only squat in front of the tail hook of the poisonous scorpion and be anxious.

And it was at this time that Xia Sheng suddenly slapped his head fiercely, turned around, ran towards Cheng Liran's corpse, and groped on it in a grand manner.

The next moment, in Xia Sheng's hands, a large number of bottles and cans appeared.

"I've really not been a robber for too many years, and I'm ashamed to forget such an important thing as searching for a corpse......"

Cheng Liran, as the Spirit Emperor who is the best at poisonous attacks, how can there be no poisonous things on his body!

And these bottles and cans found from him are not ordinary at first glance!

Regardless of what's inside, the bottles themselves are priceless goodies.

Xia Sheng would not be polite to a dead man, he took everything he could, then he opened the bottle and sniffed it separately, picked out two bottles that were not so important, poured out the liquid inside, and then returned to the meat hook of the Northern Stygian Cold Scorpion, pinched a silver needle with his fingers, and gently twisted it into the gap on the hook.

The next moment, a drop of dark green venom with a fishy smell slowly trickled into the bottle.

The seemingly quaint wooden bottle was neither corroded nor melted, so Xia Sheng couldn't help but clench his fist fiercely.

It's done!

But at this time, Meng Qi suddenly came to Xia Sheng's side and whispered to him: "Engong, someone is coming!"
