After realizing this, the faces of many True Immortals and Heavenly Emperors present all showed expressions of regret that could not be concealed.

It's a pity, if the "weird vaccine" developed by the Yuan Emperor in front of them can really help them completely avoid the erosion and pollution of weird substances, the subsequent heavenly powerhouses will definitely be able to have a clear advantage in the face of weird dark creatures.

After all, in terms of true theory, only in terms of their own combat power and cultivation, the strong people in the weird race are often inferior to the heavens in the same realm and the monks above the heavens.

And this, naturally, is because weird and dark creatures generally rely on external objects, and with the help of weird origins, they can transform and break through, so that they can cultivate to the current realm.

When it comes to deep roots, strange and dark creatures are certainly not as strong as the worlds that have grown up in a relatively "barren" environment.

It's just that the invasion of strange dark creatures is usually accompanied by a large number of strange substances, which can not only cause all souls to fall, but also erode the Great Dao of the Heavens and shake the foundation of a cultivation path, which is really creepy and chilling.

Thinking of this, everyone's faces were extremely solemn, and no one spoke for a while.

Fortunately, in the end, it was the emperor who was sitting not far from Emperor Yuan who broke the silence of this place, and saw that his eyes were shining, and he took the initiative to explain to everyone:

"Although it is true that this 'weird vaccine' cannot make me completely immune to the erosion of weird substances, after vaccination, it can also greatly enhance our resistance to weird substances, and it won't be as difficult as before."

When it comes to understanding this strange vaccine, in addition to Emperor Kaiyuan, it is naturally Emperor Zun, the Immortal Emperor, and Ye Fan, who was favored by Emperor Yuan and used as the new experimental subject, know the most.

Among them, Ye Fan's realm cultivation is even lower, and he has become a so-called "super evolutionary" on his own, and as an experimental sample, he has really played a greater role than the emperor and the immortal emperor.

In fact, it is precisely because of the sacrifice and dedication of the three of them that Emperor Yuan saved a lot of hard work and finally completed this strange vaccine.

According to the deduction of several supreme quasi-immortal emperors, even if they are creatures in the red dust and mundane worldly beings, they will never be eroded by it and fall into darkness, but will only produce more or less "antibodies" in their bodies, so that they will not be so passive in the face of strange darkness in the future.

"Although the strange vaccine has been completed, after all, we will soon leave the heavens and all the worlds, and the follow-up will naturally have to be handed over to you, so that all spirit beings in the only true realm can be vaccinated."

At the same time as saying this, Emperor Yuan's eyes were extremely deep, accompanied by the faint supreme majesty around him, which made many strong people present couldn't help but be shocked, and immediately said in unison:

"Obey the decree of the Yuan Emperor!"

"Whoa!"

Emperor Yuan's gaze drooped, looked around, took in the expressions on everyone's faces, sensed the fluctuations of divine thoughts in the underworld, and immediately nodded with a look of relief.

You must know that among the many powerhouses present, there are really many ancestors and helmsmen from the major immortal clans, families, holy lands, and ancient sects of the original heavens and ten thousand realms, who have tremendous energy.

Among them, it is natural to take the Heavenly Court created by Emperor Zun as the most.

In fact, as early as an unknown number of thousands of years ago, Heavenly Court had become a transcendent force that spanned the human realm, the strange world, and the fragments of the immortal realm, and had extraordinary influence in many ancient star fields.

And when the Heavens and Ten Thousand Worlds merged and the One True Realm was achieved, over the years, Heavenly Court naturally continued to expand, extending as much as possible into a wider area.

Fortunately, under the constraints of the Emperor Zun and the many powerhouses of the Heavenly Court, in general, the expansion of the Heavenly Court was not bloody and barbaric.

Now, whether it is the area under the protection of the Heavenly Court, or the number of all spirit beings, it can be called majestic.

In the future, with the assistance of many forces, including Heavenly Court, and the powerhouses of the Heavens, as many creatures as possible in the One True Realm can be vaccinated with the strange vaccine.

Compared to the creatures that have been corrupted by strange substances and fallen into darkness, the part of the resistance that can be inherited through vaccination is really very small.

That's why it's important to keep getting vaccinated.

Fortunately, Emperor Yuan and the others had suppressed many dark creatures before, and had harvested a large number of strange substances, as long as they were refined and refined according to the method passed down by Emperor Yuan, there was no need to worry.

Subsequently, Emperor Yuan not only distributed the strange vaccine in the Yin and Yang Furnace to everyone present, but also taught them how to make the vaccine.

Those present were the top beings of the Heavens and Ten Thousand Realms, and naturally they quickly mastered it.

In this way, Emperor Yuan finally got a thing on his mind.

And just when everyone was still observing and understanding the miracle of the strange vaccine, the emperor not far away slowly raised his head, looked straight at the Yuan Emperor above, and asked curiously:

"I don't know, 'That guy' Emperor Yuan, what are you going to do with it?"

Perhaps, most of the monks present did not know, but the hearts of the Yuan Emperor and the Immortal Emperor were like mirrors.

What the Emperor Venerable was referring to was naturally the strange creature that had possessed the Immeasurable Heavenly Venerable, the Emperor Venerable, and the Immortal Emperor in the past.

In fact, the strange substance that was first used for testing was extracted from that guy's body.

The Emperor and the Immortal Emperor were the original "guinea pigs".

Of course, Emperor Yuan not only let them be vaccinated with the weird vaccine, but also really understood the weird way, and they really benefited a lot.

At this moment, hearing the emperor's question, a look of curiosity appeared on the face of the immortal emperor on the side, and he looked straight at his own master.

I saw that Emperor Yuan's eyes were extremely deep, and countless immortal light runes flickered, and his person immediately said in a deep voice:

"Although that guy's realm is low, his origin is not small, and he will be of great use in the future."

"After bringing it to Heaven this time, I will consult with you supreme beings again."

Since Emperor Yuan said so, the two naturally did not continue to ask.

Immediately afterwards, the handsome and incomparably beautiful and outstanding Immortal Emperor spoke again, and looked at Emperor Yuan with a sincere face:

"Please let me go on the road with me!"

And Emperor Yuan didn't seem surprised by this, he had long expected that the Immortal Emperor would have this request, so he shook his head with a smile and comforted:

"Although, just in terms of realm cultivation, there is really nothing wrong with letting you leave with me, Little Phoenix—"

"But now that the only True Realm is reborn, there is still an opportunity to live, if you can survive the tribulation in this realm and become a king, or even enter the ranks of immortal kings, you will definitely be able to build the most solid Dao foundation and benefit immensely."

The Immortal Emperor knew in his heart that Emperor Yuan was also thinking about him. Although he regretted it, he finally nodded:

"Yes, Master."

At this point, the affairs of the heavens and all the worlds have come to a successful end, and the Yuan Emperor has no more concerns.
