Eternal Sword Monarch

Xia Ling quickly browsed through the documents in the room and the several rooms behind it. Many of them were descriptions of the power of "Celestial Spirits", and they were detailed down from the details of each battle as well as the effects of Dark Demon Domain's countermeasures.    

    

One could imagine, that when this Demon Cultivation Sect knew that it was destined to be destroyed, it had hidden these precious documents in the underground space. If there were any later generations who were lucky enough to see these documents, it would be of crucial importance in order to fight against the "Celestial Spirits".    

    

In the books afterwards, there was also an explanation for the existence of the First Trial Land.    

    

"... Because of these "immortal spirits" themselves, they had an extremely strong restraining effect on Yin Qi. But on the other hand, no matter how strong they are, they will never be able to control the Yin Qi. "    

    

"My Dark Demon Domain has set up another forbidden area in another hidden valley in the southern mountains. The only door that can be opened is covered by Yin Qi, and can only be opened by Yin Qi! "    

    

"In order to prevent others from entering, various Vicious Beast and mechanisms have been set up. and used the unripe 'Demon Forging Armour Beetle', as well as the entrance to the underground space, which was forged by all the Net Alloy that were gathered. "    

    

Seeing this, Xia Ling finally understood. This place was one of the last few places where the Dark Demon Domain could be used to protect one's life. It wasn't any kind of First Trial Land at all.    

    

But there really was such a coincidence. The [Demonic Collapse] cultivation technique that was left on the mountain was adopted by Su Anshan as the [Demonic Descent]. Pu Yuhee, who was eager to absorb the Yin Qi, started to do something with the words on the stone wall, bullshitting again.    

    

Who would have thought that Su Anshan actually associated it with First Trial Land!    

    

These strange mechanisms, Vicious Beast, were obviously used as a stage for the sects to select survivors ten thousand years ago. Since he did not know of the existence of the Net Alloy, he had completely forgotten about this huge door …    

    

All of these were linked together, even Xia Ling couldn't help but sigh in his heart.    

    

In the later literature, he also introduced the contents of this underground space's research on the soul of the ancient Ice Soul. However, due to the discontinuance of the research, these documents were not completely recorded.    

    

However, there was a possible weakness of "Celestial Spirits" in these documents.    

    

That was low temperature.    

    

When these 'immortal spirits' attacked, they did use elemental attacks that were similar to ice. However, Dark Demon Domain discovered that the majority of these ice attacks were in the form of ice cones and ice spears, and the temperature wasn't particularly low. They were still at a normal level.    

    

In the later stages of the battle, cultivators of Dark Demon Domain had once tried to attack using low temperatures. Yin Qi also had a low temperature familiarity, it could indeed cause a certain amount of harm to "Spiritual Spirits".    

    

However, the Dark Demon Domain Yin Qi was not a low temperature type attack, and the "Celestial Spirit" was resistant to Yin Qi. So the effect is not obvious.    

    

Xia Ling had to admire, in such a short period of time, his Dark Demon Domain was actually able to think of using the soul of the ancient Ice Soul … He could be considered to be very meticulous.    

    

Usually, these terrifying ancient beings would be used to research some pill. A unique power might be used to research some kind of cultivation technique, but the field of Dark Demon Domain research made Xia Ling's eyes light up.    

    

It was actually studying the usage of the soul of the ancient ice on cultivators!    

    

As a Demon Cultivation Sect, it was not taboo to conduct human experiments. At the same time, Yin Qi could also provide some basic support in the field of soul research.    

    

However, the powerful ancient remnants of the Ancient Ice Soul carried great power. In comparison, the bodies of cultivators were simply too fragile.    

    

However, what Xia Ling didn't expect was that his Dark Demon Domain had actually improved by ten percent. It could also be that the pressure of danger had aroused the fighting spirit of these cultivators.    

    

The processes of research and experiments, including detailed data, are obviously not reflected in the literature. In actuality, this level of human experimentation had a huge amount of data. If he planned on using paper materials, it might be able to fill up half of the spherical underground space!    

    

However, the important point of the experiment was completely recorded here.    

    

"... In his first experiment, he injected the soul of the Ancient Ice Soul into his body. The Empty Meditative Rank cultivators who have undergone the strengthening effects of the medicine are completely unable to endure it, their bodies were frozen and turned into powder. "    

    

Xia Ling was slightly surprised in his heart, this Dark Demon Domain really reached the point where one had to throw everything on the line, to the point of being desperate, and to actually directly use a Empty Meditative Rank cultivator as a material for their experiments!    

    

Even the Dark Demon Domain back then probably did not have many cultivators above the Empty Meditative Rank!    

    

"... The second experiment lowered the concentration of soul fragments from the Ancient Ice Soul, and at the same time strengthened the stimulation of the medicine. On this basis, the cultivators of the experimental body began to slowly absorb the power of the ice. But it was frozen to death before it could fully integrate. "    

    

"... The experiment stopped, and he began to lower the power of the Icy Soul Shard with all his might. and start trying to mix all kinds of drugs. "    

    

"... A cylindrical container was established to coordinate with the external input material energy reaction. Straighten the top of the container with the powerful energy of the Ancient Ice Soul and pour the liquid into the cultivator's body. "    

    

"... "The situation has turned for the better. Time is of the essence, let's start the batch experiment..."    

    

Xia Ling frowned. Since the detailed data from the experiment were not reflected in the literature, he was unable to make an accurate judgment of himself. But after three tests, they began to move towards the batch.    

    

It was way too fast.    

    

In fact, this was just human experimentation. He should have been more careful. If they were to push for the mass production at such a fast speed, there would be no chance of any accidents, and at that time, there would be an irreparable result.    

    

As expected, the follow-up situation made Xia Ling's expression turn serious.    

    

"... The batch experiment failed. Twenty-six of the thirty subjects died on the spot. Among the four people who survived, one of them combined with the fragment of the ancient Ice Soul too slowly, causing his meridians to freeze, making him look like a cripple … "    

    

"... Only the three of them were able to successfully endure through the fusion with the soul of the Ancient Ice Soul. Their bodies began to distort. His power has started to carry along the aura of ice, which hopes to reach the strongest power of a Empty Meditative Rank cultivator. "    

    

Tsk tsk tsk, Xia Ling couldn't help but exclaim in surprise. This group of people actually managed to combine the fragments of ancient creatures and cultivators. Even if it was 30,000 years ago, this kind of achievement could shock the entire world!    

    

Unfortunately, there were no detailed experimental records here. If there were any records, Xia Ling would have had to study them carefully.    

    

However, the subsequent records continued to turn in a bad direction.    

    

"... However, during the subsequent circulation, the cold energy from the fragments of the soul of the ancient Ice Soul was too strong. Through the circulation of the meridians, it might have injured a cultivator's soul. The remaining three people started to go insane … "    

    

"... Their actions were completely uncontrollable, and they began to frantically attack the people and facilities beside them. "After absorbing the souls of the ancient ice spirits, the cold energy attacks of the three of them are extremely powerful, and are not something that cultivators of the same level can withstand …"    

    

"... "With no other choice, they could only be suppressed by the rest of the cultivators. However, more than 80 of them were still killed …"    

    

So powerful? Xia Ling was slightly shocked. Three people, whether they were killed or injured, had injured around 80 cultivators of the same cultivation level!    

    

His abilities had actually improved to such a degree!
