After a night, the energy in Yu Hao's body had only recovered by about 30%. Yu Hao couldn't help but feel a little helpless, but he didn't expect that it would be so troublesome to exhaust his physical energy in one go and then recover it.
Although he had recovered 30% of his energy, Yu Hao did not try to inject energy into the sword.
However, he was also worried that he would be sucked clean again. Yu Hao didn't want to experience the feeling of weakness when all the energy in his body was exhausted. However, with the energy, it was much easier for Yu Hao to hold the long sword again.
It was just that the sword was too heavy for Yu Hao to use, even though the feeling of being connected by flesh and blood was still there.
The morning light shone on the earth again. As usual, He Xi practiced his physical fitness and swordsmanship in the open space of the broken forest. Wiping his wet silver hair, he stood quietly at the side and looked at Yu Hao, who was also waving his long sword.
"Brother, let's stay here for a while.”After Yu Hao finished practicing, He Xi handed a clean towel to Yu Hao and said,
Yu Hao took the towel and wiped the sweat on his head. He smiled and teased,"Why, little princess, are you not in a hurry to cultivate?”
However, in the past three years, He Xi was the most obsessed with cultivation. Every time he went to a place, as long as he cleaned up the biochemical mutated creatures, He Xi would rush to the next place to continue cultivating.
He Xi rolled her eyes at Yu Hao and pouted,"It's not a big deal. Brother, don't you want to build a laboratory and conduct genetic experiments on biochemical mutated creatures? I think this place is quite good."
Although He Xi really wanted to continue cultivating to unlock the shackles of his Angel Gene, he knew that Yu Hao had always wanted to find a place to stay for the past three years and conduct some experimental research on the genes of biochemical mutated creatures.
However, because he had never been in a place for more than two months, this matter had been delayed. He could not help but feel guilty and apologetic.
He Xi hesitated for a while before he said," And I think you're right, brother. I should continue my combat training now. It's better for me to stay quiet for a while and seek to unlock my genetic shackles." It just so happens that I can also learn biological genetic knowledge with you.”
" Oh, Little Princess has thought it through…" After teasing He Xi, Yu Hao immediately put away the smile on his face."Yes, it's pretty good. It's far away from the human settlement of planet Datan.”
After making up his mind, Yu Hao quickly took the materials on the spot and cut down some trees to build two simple wooden houses as their temporary residence.
He brought He Xi along and began to build the laboratory based on the knowledge about the laboratory left behind by He Ran.
Although he was prepared for the difficulties he would encounter in building a simple laboratory in Datan. However, when it really began, Yu Hao quickly discovered that he had thought too simply.
After all, the biological gene laboratory was incomparable to the simple physics laboratory that he had built for He Xi in the manor.
Not to mention the high-frequency computers, even some fine observation equipment and experimental equipment. It was not something that could be found in the cold weapon era civilization of planet Datan.
In order to complete such a laboratory, he had to help establish a complete industrial technology system that surpassed the civilization of Planet Datan without any technology, equipment, and other basic conditions.
This made Yu Hao feel a little helpless. Could it be that he had to rule this planet by himself?
As soon as this idea came to his mind, Yu Hao decisively shook his head and gave up. How much time and energy would it take? He would also have to face countless biochemical mutated creatures. Moreover, although the angels had left, there was still the existence of the Angel Base Station in outer space.
Even though they had the knowledge of Angel Technology that He Ran had left behind for them, it was only knowledge. It could only help Yu Hao avoid some side-roads in his genetic research.
However, it was not practical for Yu Hao to build his own genetic laboratory on planet Datan.
Yu Hao could only use the experience of building the laboratory in the manor to build a small physics laboratory first and hand it to He Xi to develop some equipment, especially the energy, lighting, observation equipment, etc. needed by the laboratory.
Yu Hao, on the other hand, relied on the fact that he had already activated the Angel Gene and could fly. He flew around the planet to search for various ores and materials, bringing them back for He Xi to use for research. Under the hard work of the two of them, it took nearly two years.
A huge building was slowly being built in the forest. This was a large physics laboratory that the two of them had completed. It was already equipped with some biological research equipment manufacturing functions.
As for energy, He Xi, who had experience in electricity research, easily built an electric generator outside the laboratory to provide energy for the physics experiment and also to provide light for the remaining forest.
He looked at the completed laboratory in front of him. Yu Hao couldn't help but sigh at the hardships of civilization and technological progress. He still relied on the knowledge of the angel technology civilization left behind by He Ran. It took him four years to build a large-scale physics experiment on electricity.
As for nuclear energy, although he and He Xi had left behind a theoretical basis and a large amount of data for reference, they were still able to use it as a reference. However, it was only on the blueprint and no nuclear energy laboratory had been built yet. This would be a long process.
"Big brother, our next step should be to conduct nuclear energy experiments. With nuclear energy, the energy source of the genetic laboratory can be solved.”Just as Yu Hao was sighing, a silver-haired girl who was about 1.8 meters tall walked over. She was wearing white armor and had a fragrant scent of jasmine.
" Mm, thank you for your hard work…" Yu Hao retracted his thoughts and looked at the young girl with a smile.
In four years, He Xi had still become a real young girl. Her fair face, red lips, graceful figure, and long legs all exuded an alluring charm.
"Then how are you going to thank me? Why don't you take me for a few laps?”The young girl looked at Yu Hao playfully and smiled,"
Yu Hao rolled his eyes helplessly. As he grew older, He Xi was no longer as quiet as before. Instead, he became a little mischievous and always liked to tease him. This made the somewhat mature Yu Hao somewhat unable to cope with it.
"Brother, I haven't gone out for a long time. I've finally completed the physics experiment today. Let's go out for a walk.”He Xi leaned over and suggested,"
" Mm…" Yu Hao nodded and couldn't help but rub He Xi's long silver hair guiltily."Then let's go out for a walk."
He sighed inwardly. It took more than four years to build a complete physics laboratory. In the past four years, He Xi had been doing all kinds of research, experiments, and manufacturing in the laboratory.
In order to help him build the laboratory, the two of them had been arranged to be full every day for the past four years. Other than the necessary cultivation, they were studying and sorting out the angel technology knowledge left behind by He Ran, as well as conducting various experiments.
"Pa" He Xi slapped away Yu Hao's hand that was rubbing his silver hair. He was a little unhappy and pouted,"Brother, don't always treat me like a child. I've already grown up.”
He Xi puffed out his chest.
"Yes…yes…the little princess has grown up.”Yu Hao quickly smiled and nodded. He quickly changed the topic,"Solam, we haven't been back for a long time. Why don't we go back and take a look?”
Then, he shook his head and said,"Forget it, I won't go back."”
It had been seven years since he left Solam's manor. In the past four years, although Yu Hao often searched for resources and materials all over planet Datan, he was still a little worried. He had passed by Solam, but he had never returned to the manor.
Now that he had finally completed one thing, the rest was not something that could be completed in a short period of time. He was not in a hurry. Since he had gone out with He Xi to relax, he could not help but want to go back and take a look.
Hexi laughed and said,""If you want to go back, go back. Brother, when did you learn to be overcautious?”
Yu Hao smiled brightly and rubbed the bridge of his nose awkwardly."" It's been seven years. You've grown up, but I'm a little..."
It had been seven years since he left Solam. However, between the two of them, except for Hexi's appearance, which had changed from an 11-year-old loli to a slim and graceful girl who was nearly 1.8 meters tall, she had not changed at all in the past few years. Her appearance was the same as seven years ago.
If this were to appear in front of Leon, Moore, and the others, who knew how shocked they would be. According to the age of planet Datan, he was already 27 years old.
" Hahaha..." He Xi laughed without caring about his image."Brother, this is the first time an angel is afraid of being young.”
Yu Hao helplessly rolled his eyes at He Xi and said," We Angels are a race that lives forever. In fact, we might even have almost eternal life in the future. Seven years is just a blink of an eye to us, but to humans, it's a long process.”
He Xi looked at the dejected He Xi. After all, the little girl had yet to unlock the shackles of the Angel Gene, and her lifespan was only a pitiful thousand years. Even if she lived longer, she would only be able to live for 3000 years.
He rubbed Hexi's long silver hair, but he didn't know how to comfort the little girl. After all, unlocking the Angel Gene wasn't something that could be achieved through talent and hard work. It also required a fortuitous encounter.
Most female angels were talented, and they could not unlock the Angel Gene even after working hard for their entire lives. They were missing this opportunity.
However, opportunities were too fleeting. The opportunities that every angel had to unlock their Angel Gene were different. For example, when Yu Hao unlocked the Holy Angel Gene, he still couldn't figure it out. He had a strange feeling. He had fainted for a while, and when he woke up, he had awakened.
He saw Yu Hao looking at him with concern and love.
" Brother," He Xi said with a smile," I will become an angel. Don't forget our promise."”
" Uh..." Yu Hao was stunned. He frowned and thought for a while, but he couldn't remember what agreement he had with He Xi.
" Humph…" He Xi was instantly unhappy. He stepped on Yu Hao and said angrily,""I knew you were just patronizing me."
