Using lightning as an energy source is unsuitable? How about nuclear energy?

The data on the detector was skyrocketing, and the several Dragon crystals embedded at the top of the instrument were flashing with an almost blinding red light, as if they were about to burn up at any moment.

At this very moment, as the people closest to the Formation Plate, they bore the brunt of this wash of Spiritual Qi, which felt almost tangible.

The Second Elder spread his arms again and took a deep breath.

This time, he finally felt a completely different change.

A dense aura that made every pore on his body involuntarily relax rushed towards him, permeating his limbs and bones, making him squint his eyes in comfort.

The other three Elders were the same, all closing their eyes to experience this unprecedented sensation.

However, they were, after all, only in the Body Tempering Realm and could not yet actively use Spiritual Qi to Cultivate.

But Lin Guohui, standing to the side, was different.

As a Cultivator in the Qi Refining Realm, facing such pure and dense Spiritual Qi, he almost subconsciously began to operate his Cultivation Technique.

As a result, the moment his Cultivation Technique automatically circulated for a few cycles, the Bottleneck within him shattered in response.

A stronger aura rose from his body; he had successfully achieved a Breakthrough from the fourth stage of the Qi Refining Realm to the fifth stage!

"Ah..."

"Is this the feeling of abundant Spiritual Qi?"

"It's simply... simply too exhilarating!"

Lin Guohui opened his eyes, feeling the surging Spiritual power within him, his face filled with irrepressible excitement.

"Yo, Dad, you actually achieved a Breakthrough?"

Lin Xiyue looked at her father's transformation, a smile appearing on her face.

"Hmm, this Spiritual Qi is really too dense."

"It's much more efficient than when I Cultivate using Dragon crystals. I didn't even do anything, and it just broke through my Bottleneck directly."

During this time, Lin Guohui had naturally also been using Dragon crystals to Cultivate.

However, unlike Lin Xiyue, he had to spend a lot of time each time removing the fire-attribute energy contained within the Dragon crystals.

This resulted in his results when using Dragon crystals to Cultivate being far less simple and brutal than Lin Xiyue's.

But even so, it was still a hundred times better than directly absorbing the thin Spiritual Qi of the outside world.

Who told Blue Star's Spiritual Qi concentration to be so pitifully low?

"According to the data on the instrument..."

"The concentration of Spiritual Qi around us currently has increased by more than a thousand times compared to before?!"

"It's too outrageous! This is a complete qualitative change!"

Just then, the Fourth Elder, having finished reading the data, tried his best to control his trembling arm and turned the instrument screen towards everyone.

"So... we didn't find the right method at all before?"

"To make this formation unleash its power, we must... use lightning to strike it?"

The Second Elder looked up at the slowly rotating light wheel in the air, then at the instrument in the Fourth Elder's hand, his brows furrowing.

He immediately raised his concerns: "But lightning isn't something that happens all the time!"

"It feels completely uncontrollable; we can't just have Little Gold constantly drawing lightning from the sky, right?"

"No, no, no, you're thinking about it wrong." The Third Elder waved his hand, a gleam of wisdom flashing in his eyes.

"From the current looks of it, it's not that we can only use lightning strikes."

"Xiyue was just helping us demonstrate its true method of use."

"Since it can convert any type of energy, we just need to get more energy sources within the range covered by the formation!"

The Third Elder's mind worked extremely fast, and he immediately understood the key to it.

The Second Elder's eyes lit up upon hearing this, as if he realized something: "You mean, even if we hauled thousands of tons of coal here to burn, it could convert it into Spiritual Qi?"

"That's right, Second Grandpa. Theoretically speaking, it is possible." Lin Xiyue nodded, then added: "But I don't recommend doing that."

"Because if the energy source is too low-grade, the conversion efficiency of the formation will probably be very poor."

"The reason the effect was so explosive just now is mainly because the energy density of the lightning bolt that Little Gold drew down was too high."

"Hmm, Xiyue makes sense." The Grand Elder spoke in a deep voice: "However, as the Second Elder said, lightning is not completely controllable."

"To make this formation perform at its best, we must find it a more suitable energy source!"

As soon as the Grand Elder said this, two words popped into everyone's minds at almost the same time.

"Nuclear energy!"

The five of them said in unison, then looked at each other with some surprise.

"Hahaha, it seems we all thought of the same thing."

The Fourth Elder laughed first, the excitement on his face impossible to hide.

"Tsk, if we are talking about energy sources with high energy density and sufficient stability, then currently on Blue Star, besides nuclear energy, what else could there be?"

The Third Elder nodded noncommittally, clearly agreeing with this plan.

"Use nuclear energy as an energy source for the formation to convert?"

Lin Guohui listened to this bold idea; although he felt it was very appropriate, he was still subconsciously a little worried.

"It sounds perfect, but... will there be safety issues?"

"After all, nuclear energy is not something to joke about. If it leaks or even causes an explosion..."

"Dad, are you treating Little Gold like air?"

Lin Xiyue pointed to Little Gold, who had already returned to her side and was as quiet as a golden statue, and rolled her eyes at Lin Guohui.

"With Little Gold sitting here, as long as it's not a crisis that could blow Blue Star to smithereens, it can suppress it!"

"Uh... alright."

"I was overthinking it."

Lin Guohui came back to his senses and realized that the current conditions were no longer what they used to be; his thinking was still stuck in the past.

"That's right, with Little Gold here, we can completely let go and try it boldly."

The Grand Elder had no concerns about this and quickly made up his mind.

"However, using nuclear energy for experiments is a major project that requires time to prepare. From mobilization to transportation, and then to installation and commissioning, I'm afraid it will take at least two or three days to prepare."

The Fourth Elder made a slight estimate of the time.

"No matter, two or three days is fine."

"I will arrange it right now!"

As he said this, the Grand Elder immediately took out that special mobile phone and gave a series of instructions concisely.

Then he put the phone back into his pocket.

Just at this moment, a slight tremor came from the ground.

Everyone was stunned, then looked towards the distance in unison.

They saw Little Red's massive body, now striding with its four thick, short legs, rushing towards here like an out-of-control heavy truck.

And beside it, a similarly huge, fire-red three-headed giant snake was closely following, flicking its tongue, its speed not slow at all.

"Ha, isn't this our great hero Little Red?"

"What? Were you two also attracted by this dense Spiritual Qi?"

The Second Elder was amused.

Looking at the impatient appearance of these two giant beasts, how could he not guess what they were here for?

"Tsk tsk tsk, unfortunately, you two guys are late."

"That lightning bolt has already been mostly refined, and the Spiritual Qi around here is constantly diffusing outward; it's not as dense as it was before."

Lin Xiyue crossed her arms and shrugged gloatingly.

Little Red had already successfully rushed to the front, and stopped with a sudden screeching halt.

Hearing this, a flash of extremely human-like disappointment appeared in its huge eyes, as if it were regretting that it had arrived too late and missed this gluttonous feast!

However, the three-headed snake beside it clearly didn't think so.

Although it couldn't eat the fattest meat, since it was already here, drinking some soup would do!

So its three huge snake heads immediately rose high, and it began to gulp down the surrounding air, frantically sucking the remaining Spiritual Qi into its body.

Seeing this, everyone did not stop its behavior.

Because this three-headed snake was now one of their own.

Ever since Little Gold returned from Mount Fuji and brought it along, it, like Little Red, had very consciously submitted to Lin Xiyue and acknowledged her as its master.

It was precisely because of this that everyone could let it move freely within the Taibai Mountain Base without restrictions.
