Trading system, I exchanged vegetables for golden pills.

Ye Chen ignored Da Huang and finished setting up the formation. After adjusting it for a while, he nodded in satisfaction.

He still set up the core of the formation in the Big Yellow Nest.

With a powerful, seven-level Qi-refining beast watching over things, it's absolutely safe. Nobody would ever guess!

Even if a thief breaks into a house, he can't just steal the doghouse... unless he's a dog thief.

Moreover, after Dahuang learned about the benefits of the Spirit Gathering Array, it became its lifeline. Anyone who dared to destroy the Spirit Gathering Array would be making trouble for Dahuang.

Then we'll have to ask its seven-level Qi-refining paws if they agree.

The spirit-gathering array has already started operating!

Ye Chen felt a refreshing breeze in the air, and his whole body felt a little more comfortable.

Of course, the concentration of spiritual energy doesn't change much in a short time. In an environment with almost no spiritual energy, even the best formation will need a certain amount of time.

For Ye Chen, the significance of successfully replicating a spirit-gathering array was far greater.

After his mental energy recovered somewhat, Ye Chen tried to inscribe the array plate again.

Although the array plate was quite large and the array patterns were complex, Ye Chen had inscribed so many of them in succession that there was no major problem.

It took Ye Chen half an hour to successfully inscribe an array plate.

The following night, Ye Chen struck while the iron was hot and inscribed array patterns on the remaining jade stones.

It was already two in the morning when Ye Chen finished engraving all the jade stones.

This time, Ye Chen didn't cultivate; instead, he went straight to sleep!

He was genuinely exhausted. He hadn't felt sleepy for a long time since he started cultivating, so it seemed that he had really overexerted his mental energy this time.

Ye Chen didn't force himself; he let his body's physiological reactions take their natural course.

Take a break when you need to!

However, when Ye Chen woke up, it was already past 12 in the morning!

"Uh—ah—"

Ye Chen stretched lazily and checked the time: "Damn, it's already 12:12! I've slept for so long, why didn't anyone wake me up to cultivate?!"

Ye Chen got up, stretched his arms and twisted his waist for a while, before preparing to go out.

He hadn't slept this long and comfortably in a long time.

I slept until past noon the next day, which is something that almost never happens to me.

Since he started practicing, he has been getting up at 5 a.m. almost every day, very regularly.

It seems I really did use up a lot of mental energy last night, which is why I slept so well!

Ye Chen was about to use his mental energy to check who was in the courtyard when he was slightly startled the moment he released his mental energy.

His mental energy's coverage area has increased so much...

Originally, if his mental power were to cover the entire area, it would be within a radius of about 12 meters.

But now it can cover a radius of about 18 meters, which is a full six or seven meters more in coverage.

Ye Chen tried point-to-point mental energy probing again; he could even extend his mental energy dozens of meters away.

"Holy crap—"

Ye Chen couldn't help but exclaim in surprise, "Has my mental strength increased? But this increase is a bit too fast!"

Judging from his actual performance, his mental strength has indeed increased without a doubt.

Ye Chen hurriedly checked his spiritual sea and suddenly discovered that it was slightly larger than yesterday.

This time it's really big, you can clearly see it.

He still remembered his spiritual sea from yesterday, which was about two-thirds of its current size. How could it have grown so much in just one night?!

Ye Chen was a little excited. He had personally experienced the benefits of strong mental power and knew what it meant.

Whether it was dealing with Master No. 999 or inscribing array patterns, his powerful mental strength played a significant role.

Now that his mental strength has suddenly increased, how could he not be happy?

Moreover, mental power is even more difficult to cultivate than spiritual power!

Otherwise, spiritual milk wouldn't be so precious!

There was another reason for Ye Chen's surprise.

Previously, he didn't know how to cultivate mental power.

However, judging from the changes in his spiritual sea, Ye Chen seems to have come up with a simple method for training his spiritual power.

That means using it more! Using it to the extreme, like what he did last night.

Once my mental strength recovers, it should increase.

Just like physical training.

There are many ways to consume mental energy. Inscribing array patterns is one, casting illusions is another, and using the Bagua Mirror is yet another.

Of course, mental exploration, telepathic communication, and so on are all possible.

No wonder the big shots all like to use telepathy; it turns out they're constantly training their mental strength.

It seems we'll have to get Da Huang and Dongzi to communicate more using their mental powers in the future.

This way, your mental strength will increase faster!

Of course, Ye Chen wasn't sure if it would be 100% successful; he could only say that this mental power was worth trying!

Ye Chen composed himself. Besides Da Huang, A Long, Dong Zi, Qi Li Rong were also present at the house.

The three people and the dog were focused on their cultivation, and it seemed they had been cultivating for quite some time.

Ye Chen was so focused on sensing his spiritual power that he didn't notice anything different about the spiritual energy. Now, after carefully sensing it, he discovered that the spiritual energy was three or four times more concentrated than yesterday.

Although Ye Chen still found the spiritual energy concentration somewhat unappealing, it was even inferior to the Qi-replenishing pills.

However, it's already quite good, mainly because it's free and suitable for multiple people to practice at the same time.

Of course, when multiple people cultivate at the same time, it's a competition of who can absorb more and faster, since the total amount is also limited.

Ye Chen didn't disturb them and went to the kitchen to get something to eat. When he got to the kitchen, he found that a bowl of noodles had been left for him to keep warm.

Judging from the cooking skills, it must have been Xiao Qi who cooked it. Dongzi and Along can eat it, but they certainly don't have this level of skill when it comes to cooking rice.

Ye Chen smiled slightly and began to eat heartily.

Ah Long and the others must have heard the commotion, because they all stopped cultivating.

Xiao Qi was the first to walk into the restaurant: "Master, you're awake! You've slept for quite a while today!"

Ye Chen glanced at her sideways: "You know it's been a while, but you didn't even call me? If I'd died, you probably wouldn't even know."

"Pah, pah, pah, what unlucky things are you saying, Master?" Xiao Qi waved his hands wildly in the air, as if trying to dispel bad luck.

Dongzi grinned: "Brother Chen, your snoring is deafening, you're obviously sleeping soundly, so we didn't want to disturb you!"

Ye Chen stubbornly retorted, "Nonsense, I never snore when I sleep, you must have misheard!"

"Yes, yes, we misheard. By the way, Brother Chen, why is your spiritual energy so abundant?"

Dongzi asked, puzzled.

As soon as he said this, Ah Long and Xiao Qi both looked at Ye Chen curiously.

"Didn't Dahuang tell you?" Ye Chen looked at the group.

"No, Da Huang is very tight-lipped, acting all mysterious!" Dongzi pouted.

"What did it say?" Xiao Qi asked, full of questions. "We can't understand anything it's saying, so how can you understand Big Yellow's language?!"

Xiao Qi was unaware of the concept of telepathic communication, so he was somewhat confused.
