Hearing that Huo Yuhao had returned from controlling the flood, Marshal Evil Dragon immediately put down the affairs at hand and went out to welcome him.
According to Huo Yuhao's request, he handed the natural magnetite collected from within the country to craftsmen to be processed into models on the blueprints, and then sent them to the middle reaches of each river section for installation.
Huo Yuhao deeply admired Marshal Evil Dragon's ability to govern the army. To achieve this in just half a month, it would be impossible without the army's strict execution.
There was still a month and a half before the start of the Continental Advanced Soul Master Elite Tournament. Huo Yuhao simply concealed his identity and devoted himself to the scientific research and construction of the Heaven Soul People's Republic.
In the next half month, Huo Yuhao adapted measures to local conditions, using rare metals unique to the Douluo Continent to replace the generator materials of his previous life, and designed construction plans.
Because of the existence of the profession of soul master, the assembly of mechanical parts and engineering infrastructure construction, which originally required various machines to complete, could be completed in the shortest time. Huo Yuhao simply shared the principles with experienced soul engineers, letting them use the core arrays of soul tools to replace some complex mechanical structures, completing the development of hydroelectric generators suitable for this world.
It had to be said that as long as the principle was correct, humans could control electricity in any world.
Especially those elite soul engineers engaged in soul tool research. When they saw the electric arcs released by the small metal coil in Huo Yuhao's hand, they were all shocked speechless.
No need to circulate soul power, nor need a sealed milk bottle. Some rare metals could actually generate lightning out of thin air.
When the power of lightning could be completely controlled by humans, the era where soul power could do everything might become history.
Being able to achieve this step was also Huo Yuhao's limit. After all, he was not a scientific researcher in his previous life, so he could only use the knowledge that ordinary people had basically learned.
Of course, this theoretical knowledge was still too advanced for a world ruled by theocracy. Those elite soul engineers cultivated by Xian Lin'er all regarded Huo Yuhao as a faith without exception, which made Huo Yuhao feel very embarrassed.
Over the past half month, Huo Yuhao repeatedly proposed advanced concepts brought from that world and constantly conducted experiments for the benefit of ordinary people.
There were many failed cases among them. After all, the material composition of this world was not consistent with Huo Yuhao's original world. For example, energy like soul power transformed from the human body could not be applied with the theoretical knowledge of that world.
Huo Yuhao's trip could be considered to have come to an end for now. He had other more important things to do.
Later, it would depend on the technological development speed of the Douluo Continent civilization itself.
...
Huo Yuhao finally waited for Zhang Lexuan's return.
However, this gentle and virtuous Eldest Senior Sister didn't look very good at this time.
The ideology dissemination teams Zhang Lexuan sent to the three empires of Dou Ling, Star Luo, and Sun Moon were completely wiped out.
Regarding this, Huo Yuhao didn't find it strange. This ideological proposition was undoubtedly too impactful for a continent where the imperial system had lasted for tens of thousands of years.
Even if there were no institutions supervising this aspect in the three empires, the bottom-level common people who were happy to be slaves were also willing to report these teams spreading ideas.
So their sacrifice was within Huo Yuhao's expectations.
At least, in this era, it was impossible to fundamentally save the ignorant bottom-level common people.
However, when a voice appeared, there must be an echo.
Huo Yuhao was not in a hurry. Rather than forcefully turning the continent into what he hoped for, it was better to give it time to evolve on its own. Just keep spreading that ideology.
Unless the scum humans of the Douluo Continent really didn't need saving.
With the matters in Heaven Dou settled, Huo Yuhao continued to travel north. This time, he was going to the Extreme North to take the Snow Empress to the Dragon Realm and help her solve the next tribulation.
The accompanying personnel were Die Qiu and Zhang Lexuan.
This time he spent less than half a day to enter the Core Circle of the Extreme North.
The Core Circle of the Extreme North Ice Sheet was a forbidden zone for humans, famous alongside the Great Ferocious Lands in the Star Dou Great Forest. Even the Evil Spirit Forest of the Sun Moon Empire was much inferior.
The Evil Spirit Forest was listed as a forbidden zone for humans only because of the existence of the Evil Eye Tyrant Lord. In contrast, there were a large number of fierce beasts in the Great Ferocious Lands of the Star Dou Great Forest. As for this Core Circle of the Extreme North Ice Sheet, the most tyrannical thing was not the threat of soul beasts, but the environment.
In this environment, even a Titled Douluo like Zhang Lexuan would find it difficult to survive for a long time.
The air in the Extreme North was incomparably dry, the biting cold wind was like sharp blades, not a blade of grass grew, and the ultra-low temperature would continuously consume a soul master's soul power. In such a place, normal humans had almost no way to survive.
Moreover, ice attribute soul masters were few after all, so very few soul masters came here to hunt soul beasts. As a result, in recent years, the overall strength of soul beasts in the Extreme North Ice Sheet had grown to a considerable level.
This place was different from Star Dou. The fortune of the Emperor Auspicious Beast far away in Star Dou rarely descended here, which destined that the overall quality of soul beasts in the Extreme North could not compare with Star Dou.
When Huo Yuhao brought Zhongli Yu here last time, they were protected by the silkworm clothes of the Skydream Iceworm, which allowed them to resist the severe cold. Returning after several years, his mood inevitably felt somewhat different.
Back then, when he first came here, Huo Yuhao was as weak as an ant. Then he encountered the joint attack of the Ten Thousand Demon King and the Ice Empress, almost losing his life here.
Huo Yuhao subconsciously spread the wings bestowed upon him by the Ice Empress. His physique had been strengthened many times, and now this external soul bone had also changed greatly.
Since the Skydream Iceworm burned itself in sacrifice, Huo Yuhao could clearly feel that the Ice Empress spoke less, or perhaps she was originally not the type good at expressing herself.
The three continued to move forward. Huo Yuhao didn't ask the Ice Empress either. When they reached the approximate area, the soul spirit contract with the Snow Empress would naturally guide him in the direction.
Another purpose of Huo Yuhao's trip here was to see if the Ice Bear King and the Titan Snow Demon King were willing to sign the Soul Spirit Symbiosis Contract with his companions.
After all, this symbiosis contract was different from the soul spirit contract created by Electrolux on his deathbed in the original timeline. It would not cause any harm to the soul beasts.
As for Huo Yuhao himself, before leaving, Gu Yuena specifically instructed him not to attach any more soul rings to himself.
Once Huo Yuhao skillfully used the seventh soul ring brought to him by Gu Yuena, he could immediately obtain the eighth soul ring.
Feeling the biting cold wind, the Ice Empress in his spiritual sea muttered to herself: "It feels so good to be back! If I were still the ruler here in the future, how wonderful that would be. Here, Xue'er and I have no natural enemies, and no one can contend with us. This is our paradise."
Huo Yuhao was silent. When he fused with the Ice Empress and the Ten Thousand Demon King back then, Electrolux hadn't created a complete Soul Spirit Symbiosis System yet. Like the Ten Thousand Demon King, both of them dedicated everything they had to Huo Yuhao.
Seeming to know what Huo Yuhao was thinking, the Ice Empress's soul spirit suddenly projected to the outside world. It was a charming young girl with emerald green twin tails.
Zhang Lexuan and Die Qiu were stunned when they saw the Ice Empress appear, especially Die Qiu, who could feel the powerful aura belonging to a fierce beast from the Ice Empress.
"Yuhao, no need to mind. Actually, being able to stay in your spiritual sea all the time like this might not be a bad thing," the Ice Empress said with a smile.
"Why do you say that?" Huo Yuhao was a little confused. By now, presumably both the Ten Thousand Demon King and the Ice Empress could see that Huo Yuhao had no intention of becoming a god.
This meant that in the future, if the Ten Thousand Demon King and the Ice Empress wanted to regain their bodies and restore their freedom, the difficulty would undoubtedly be a level higher than in the original timeline.
However, even in the original timeline, they didn't regain their flesh and restore their physical bodies.
"Since that guy Tianmeng left, I faintly feel that having a cage like you to trap us and protect our safety all the time is actually not bad."
Huo Yuhao listened in a daze. It was hard to imagine these words coming from the proud Ice Jade Empress Scorpion.
The Ice Empress floated to his side and continued to smile: "After entering the human world, I gradually gained an understanding of the human world.
"Yes, in the past days, we always hated humans very much, hated them for disturbing our lives." The Ten Thousand Demon King added: "However, compared to the soul beasts in the Star Dou Great Forest, the Ice Empress's side is actually harassed by humans less. Following you, I have to admit that humans possess wisdom and creativity surpassing us soul beasts."
"We can only adapt to nature, but they are changing everything. This is also why human soul masters are so weak when they are born, but can eventually rule the entire continent."
