"What?" Everyone looked over in surprise. "Academician Chao, isn't this a violation of regulations?" a researcher whispered, a look of deep concern in their eyes.

"Really?" Yu Kai, Xia Shihan and Wu Dahu all stared at him closely, their eyes full of surprise and disbelief.

"Really? But building a mecha requires a lot of manpower and material resources, and you need to pay for it." Academician Chao looked at Yu Kai, then turned his gaze to Xia Shihan and the others, his expression serious and earnest.

Looking at Yu Kai's expectant eyes, Xia Shihan answered without hesitation, "No problem, Academician Chao, I can make the decision on this!" Her tone was decisive and confident.

"Okay, one more thing is that I will only equip the mecha with a power system, a balance system, a protection system, and an intelligent assistance system. You need to provide the weapons used in the weapon system yourself." Academician Chao paused as he looked at the three of them, with a hint of apology in his eyes.

"In other words, the weapon system, whether it is a bullet or a missile, needs to be provided by ourselves, right?" Yu Kai looked at Academician Chao and asked seriously.

"That's right! How much power you can exert depends on the energy you use!" Academician Chao looked at Yu Kai and nodded, his eyes full of encouragement and expectation.

"Academician Chao, please help me build it. My mother will find a way to get the money. My mother loves me the most!" Yu Kai said excitedly, grabbing his arm.

"Okay, okay! I am full of hope for your mecha!" Academician Chao nodded repeatedly with a gratified smile on his face.

In the days following Luo Yingxue's departure, Yu Kai devoted himself to studying and documenting the mecha production workshop. His thirst for knowledge about mechas seemed insatiable, like a parched earth longing for rain. To delve deeper into the mysteries of mechanical and psychic control, Yu Kai specifically requested that Elder Chao build him a robotic arm. Wu Xiaohu, a relatively weaker member of his mother's staff, unfortunately became Yu Kai's "experimental subject." Yu Kai allowed Wu Xiaohu to control the robotic arm with his psychic powers, while he observed intently, his pen relentlessly recording every detail, every energy fluctuation, and every mechanical reaction. Wu Xiaohu was constantly tormented, and only when his spiritual power was completely exhausted would Yu Kai temporarily release him, allowing him a respite.

According to Xia Shihan's description of the realm, he was only at the peak of the second level of martial arts, among the twelve realms of spiritual cultivation. Their specific realms were divided into 12 levels, each with four stages: early, middle, advanced, and peak. The advancement of realms meant a leap and transformation in strength, and each level presented an insurmountable chasm.

Warriors are the first to explore spiritual power. Once they succeed in attracting spirits, they already possess strength and speed far beyond that of ordinary people. Ordinary mortals cannot get close to them at all, just like an ant facing a giant.

Martial artists have gone a step further and have become able to skillfully use a small amount of spiritual power. Not only has their physical fitness been greatly enhanced, they can even catch bullets with their bare hands. In the eyes of ordinary people, they are like gods of war and are awe-inspiring.

The strong ones at the Martial King realm are already able to use their spiritual powers to fly over eaves and run on walls. Their martial arts value has been greatly improved compared to that of martial artists. Xia Shihan and the other four are at the peak of this realm.

Wu Dahu has successfully reached the level of a grandmaster, and has reached the level where he can use psychic energy to fly short distances. His every move has the power to split mountains and crack rocks.

Those who have reached the Grandmaster level are even more powerful. They can easily block ordinary gun and artillery attacks and remain safe and sound in a hail of bullets, just like an indestructible body of diamond.

Spiritual practitioners at the clan king level have begun to be able to use spiritual energy to unleash powerful attacks, which are powerful enough to destroy tanks, armor and other heavy military equipment at will.

At the sage realm, one's strength is beyond ordinary things. One can use psychic powers to fly and hide in the ground, and possesses the incredible power to move mountains and fill the sea, just like a mythical god come to earth.

The strong ones in the Saint King realm have reached a higher level. They are able to use their spiritual energy to escape into the void and move freely in the void, as if they have transcended the constraints of the earthly world, which is beyond the reach of others.

The existence of the Holy Emperor realm is already synonymous with destroying the world. He can use psychic energy to easily destroy small planets. His power is so terrifying that it can be said to surpass the existence of nuclear bombs, and he is like the master of the universe.

The strong ones in the realm of the Venerable have reached a realm that is almost mythical. Such strong ones have ignored the void and can travel freely. Yu Kai's mother Luo Yingxue is such an awe-inspiring strong one, like a queen high above.

Going further up is the realm of Great Venerable, whose power is enough to easily destroy a large planet. Wherever it goes, it is reduced to ruins, like the destroyer of the universe.

As for the realm of Heavenly Venerate, it is an invincible existence in the starry sky. Its prestige and strength are enough to make the entire starry sky tremble, as if it is the eternal overlord.

The more he learned, the more insignificant Yu Kai felt. The thought of his mother leaving Earth one day to search for his father, and him being unable to help, becoming a burden to her, filled him with deep remorse. A wave of powerlessness washed over him, leaving him feeling incredibly oppressed, as if an invisible mountain had crushed him.

He touched Zhu Bei'er beside him, took out his phone and checked the news. He wondered how his mother was doing, and he couldn't help but feel a little worried. The page kept refreshing with various pieces of information, but none of them were what he expected.

"Master, are you worried about the young lady?" Xia Shihan walked over with a cup of hot tea. Her steps were light, like falling petals, and there was a gentle smile on her face, and that smile was like the spring sunshine.

"Sister Shihan, it's been several days, why is there still no news from my mother?" Yu Kai took the teacup and said worriedly, his hand holding the teacup unconsciously tightened.

"Don't worry, young master. The young ladies are doing well! They should be back soon!" Xia Shihan smiled.

"What's going on? Is he so easy to talk to?" Yu Kai asked doubtfully, his eyes full of confusion.

"Of course not. The young lady and her companions were ambushed by them as soon as they arrived. But how could they be a match for the young lady? They were easily wiped out by the big tiger and broke out of the blockade!" Xia Shihan said with disdain, with a hint of pride on her face.

"What happened next?" Yu Kai continued to ask, eager to know what happened next.

"That night, Yaqi and Dahu evaded all security and secretly captured their president! The next day, after working all morning, they discovered that the president they were guarding had his mouth gagged and fallen on the flagpole!" Xia Shihan couldn't help laughing when she said this. "That scene really pissed off those top brass from the United States, but they were helpless." Her laughter was crisp and pleasant.

"Have they compromised? Have they returned the 600 tons of gold?" Yu Kai continued to ask, his eyes full of eagerness and expectation.
