Trading system, I exchanged vegetables for golden pills.

After cleaning up all the traces, Ye Chen did not delay and immediately began to set up the spirit gathering array!

Under his mental influence, he quickly came up with a draft in mind.

He took the Seven Star Sword and started digging a hole in the courtyard.

About 15 minutes later, Ye Chen successfully set up the spirit gathering array.

Unless you dig three feet into the ground, outsiders probably won't be able to figure out anything.

Ye Chen seized the opportunity and began setting up a protective array for his home. Since the protective array had many bases, it took a while to set it up.

Moreover, the protective array is a defensive formation that requires spiritual energy to function.

The simplest way is to place spirit stones in the protective array, making them the energy source for the home's protective formation.

Of course, this method is rather extravagant and wasteful, at least for the cultivators on Earth.

Spiritual energy is scarce on Earth, and spirit stones are extremely rare; they probably don't even exist on Earth.

He only had a few dozen coins left, and he couldn't afford to waste them like that.

Therefore, Ye Chen chose another method, which was the nesting of formations.

By nesting the Spirit Gathering Array and the Home Protection Array together, the spiritual energy absorbed by the Spirit Gathering Array can power the Home Protection Array, providing it with energy.

Although this method is not as direct as using spirit stones, and the charging time is relatively long, possibly one or two days, since it takes some time for the spiritual energy of Blue Star to gather, it has the advantage of being sustainable.

As long as it saves spirit stones and still allows the formation to function properly, that's fine.

Anyway, this formation is only used a few times in emergencies, so it's definitely enough.

You can just leave it there to slowly recharge, and since the Spirit Gathering Array continuously gathers spiritual energy, the protective array will last longer.

This was also Ye Chen's first time trying to nest two different formations.

Fortunately, the key points of the formation were explained quite thoroughly, and his mental strength was also quite strong, which meant he was able to have a comprehensive view of the whole situation.

Taking a God-like perspective reduces the difficulty by several levels.

After trying seven or eight times, Ye Chen gradually figured out the trick.

If an ordinary person estimates that they would need to try many more times to arrive at the optimal solution, that is the advantage of having strong mental fortitude.

Ye Chen's father returned from the fields and, seeing Ye Chen fiddling with something in the yard, asked in confusion, "What are you doing, kid? Your grandfather didn't leave any treasure; you don't need to dig!"

"Dad, come inside first. I'll get everything set up and then we can talk slowly!" Ye Chen didn't have time to explain much right now and was still focused on setting up the formation.

This cloth was being laid out until after noon!

Ye's mother had already cooked the food, but seeing that Ye Chen was focused on tinkering with something, she didn't dare to disturb him.

"What is Chen'er doing?" Ye's mother asked Ye's father in confusion.

"How would I know? But it seems to be something like an array, right? I saw him bury a lot of jade stones underground, each at least the size of a fist!" Father Ye had been watching from the doorway for a long time and had figured out a thing or two.

Just then, Ye Chen took out a piece of jade the size of a small vegetable bowl from his backpack and buried it!

The backpack was just a pretense, meant for my parents to see!

Otherwise, if something could magically appear out of thin air, the storage ring would require a lot of explanation.

Ye Chen doesn't plan to reveal this yet; the fewer people who know, the better. Even his parents don't need to know.

Knowing too much can be stressful.

Mother Ye stared wide-eyed in astonishment: "This, this is the fist-sized jade stone you were talking about? Your fist is that big?"

Mr. Ye opened his mouth: "Uh, it was indeed the size of a fist before, but this piece is bigger now!"

"How much does such a large piece of jade cost? It must be expensive, right?" Ye's mother couldn't help but ask.

"Hey, you're almost at the second level of Qi Refining, stop talking about money all the time!" Mr. Ye glanced at Mrs. Ye.

"Of course you don't care if you didn't earn the money!" Ye's mother glared back.

After Ye Chen had buried three jade stones, each the size of a vegetable plate, in a triangle, he clapped his hands!

It's finally done!

Seeing that Ye Chen had finished fiddling with it, Ye's mother finally spoke up: "Chen'er, what are you doing? You've been working on this for ages, you haven't even had time to eat? These pieces must be jade, right?"

"Okay, Mom and Dad, let's go inside and talk while we eat." Ye Chen smiled and walked over, pushing the two elders into the house to eat.

During the meal, Ye Chen gave a brief explanation of the formation.

Since they would be dealing with these two formations for a long time, Ye Chen couldn't hide anything from them.

The two listened intently to Ye Chen's words the whole time, barely eating any of the food as it got cold. It would be a lie to say they weren't shocked.

However, since they had already accepted the matter of cultivation, accepting an array formation would be relatively easy for them.

The Spirit Gathering Array is a self-operating array. Once the array is formed, it operates on its own without human intervention!

Ye Chen set up a control method for the protective array. To activate it, one only needs to inject spiritual power into the array's core, making the operation quite simple.

Ye's father couldn't wait and went straight to the courtyard, where he channeled his spiritual energy in the direction Ye Chen indicated.

However, it seems nothing happened!

Father Ye looked around, somewhat suspicious: "Chen'er, why isn't he reacting?"

Ye Chen didn't speak, but walked straight outside the courtyard and touched the air with his hand.

He used his mental energy to investigate the entire time, and immediately noticed the changes in his surroundings after Ye's father injected his spiritual energy.

A transparent energy barrier seemed to appear out of thin air, enveloping the entire old home.

Even with a close look, Ye Chen couldn't discern anything unusual with the naked eye. He only felt that the air seemed to distort slightly, and then there was no other special visual feedback.

This energy barrier seems to be perceptible only to those with mental power!

Ye Chen touched it with his hand, and it felt like touching something soft and bouncy, as if he were stuck in mud and couldn't get through.

It's somewhat like a non-Newtonian fluid, but not quite.

Ye Chen exerted a little force, throwing a punch with the strength of an adult.

When his fist touched the energy barrier, the barrier acted like a thick barrier, preventing his fist from penetrating even a fraction of the way.

Ye Chen could even clearly feel a force of recoil returning to his hand.

The force of the recoil was similar to the force of his punch.

Ye Chen was somewhat moved; the force of the rebound was a bit beyond his expectations!

He increased his strength slightly, throwing another punch with twice the force of an ordinary person.

However, this time the feeling was even more pronounced; the energy barrier had become harder, and the counterforce had also become stronger.

This energy barrier seems to be the type that becomes stronger when faced with a stronger opponent.

When there is no hostility, it is soft and doesn't feel like much; in fact, it feels quite comfortable to touch.

However, it begins to harden under strong attack, becoming as solid as a rock, giving it an unshakeable feel.

I just don't know how much force it can withstand, or what its limit is.

Ye Chen gradually increased his strength, and finally, mimicking the impact of a car, he delivered a powerful blow.

As a result, he was thrown a great distance by the powerful rebound force...
