Chapter 117: Secret Realm of Spiritual Medicine

Yun Jihan grabbed Yun Su's sleeve and asked nervously, "What happened to them?"

Yun Su rubbed his head and said, "It's okay, I just entered a fantasy world, don't worry."

Jiang Biechen can be said to be the biological son of this world. Yun Su would not worry about him no matter who he was worried about, because it was impossible for Jiang Biechen to fall into this kind of illusion.

"How can we wake them up?" Jiang Biechen asked with a frown.

Yun Su tapped the space defense barrier with his fingers, and a ripple immediately appeared. "It's very simple. Once this barrier is broken, they will naturally wake up from the illusion."

It took Yun Su an hour to determine the scope of the entire restriction. He then looked up at the entire valley and instantly knew how to break the restriction.

Taking out the materials, Yun Su began to refine the formation flags on the spot. After three hours, ten formation flags with black forbidden runes were refined by Yun Su.

With the formation flags, Yun Su began to try to break the restriction on the ground. When he had tried almost everything, Yun Su immediately put away the formation flags, came to the sky above the valley, moved the formation flags to a fixed position outside, and the talisman pen kept drawing ancient and mysterious runes in the air.

Runes were injected into the restriction, and there was no change at first. Yun Su injected a few more runes, and instantly the restriction began to tremble violently, and Shen Yuhan and others suddenly vomited blood.

"not good."

Yun Su immediately realized that some of his steps were wrong. His two hands immediately waved in the air, leaving afterimages, and the flags kept changing their positions. Yun Su did not stop until the restriction calmed down.

Throwing two bottles of healing and blood-replenishing pills to Jiang Biechen, Yun Su said, "If they want to break through later, you can give them the pills."

Jiang Biechen nodded, signaling Yun Su to rest assured.

Seeing this, Yun Su did not delay any longer. After all, the longer they were trapped in the illusion, the greater the damage to their consciousness.

Yun Su began to try continuously. The placement of the flags kept changing, and runes were injected into the space defense restriction one after another.

After trying no less than a hundred times, Yun Su finally succeeded in completely controlling the space defense restrictions below.

At this time, a night had passed. On the morning of the second day, Yun Su descended from the sky, and Shen Yuhan and others woke up from the illusion.

Fang Jinnian looked around in confusion, "Didn't I already go home? Why am I still here?"

The others also looked a little confused, but they didn't say anything. They just looked unhappy, and it was obvious that they had realized that everything that had just happened was just an illusion.

"You've fallen into an illusion and haven't left the Wuyun Mountains." Yun Su pushed his glasses and said lightly.

He wanted to break the restriction as quickly as possible, but although he was the best in alchemy, he was only proficient in formations and restrictions, so it took him some time.

Jiang Biechen has a talent for formations, but he has not yet mastered it, and he only has a vague understanding of many things. He can't help at all with this kind of space defense restriction.

"It's just an illusion." Fang Jinnian felt a little regretful. In the illusion, he had already established a family and a career, and became a martial arts master. It would be great if he was really a martial arts master.

Yun Su ignored the disappointed or regretful expressions on everyone's faces, took Jiang Biechen's hand and walked into the valley.

"Let's go in."

Yun Jihan followed him without even having to shout, walking on his two short legs, "Dad, wait for me."

While he was lying on the ground, he called Yunsu "Dad" and didn't feel embarrassed at all.

Seeing this, Shen Yuhan, Fang Jinnian and others followed in.

As soon as he entered the valley, Yun Su immediately realized that although the spiritual energy here was less than half of that in the Cangyuan Continent, it was more than ten times that outside. This place was simply a paradise for cultivation.

Moreover, it was exactly as Yun Jihan said, there was no smell of monsters in there, except for the spirit butterflies flying among the flowers.

Looking at the large area of ​​elixirs with a faint spiritual aura inside, Yun Su was a little shocked. This turned out not to be the cave of a powerful person, but a secret place.

It is incredible that there are secret places on earth.

However, secret realms are often filled with dangers and opportunities.

Since he had already cracked the restriction outside, Yun Su naturally put away the formation flag. But at this moment he took out the formation flag again.

A spirit gathering array was set up directly in the center of the valley, and instantly all the spiritual energy in the entire valley began to surge towards them.

"The spiritual energy here is rich, it is a rare treasure land for cultivation, take this opportunity to cultivate."

Yun Su was the first to sit cross-legged. After hearing what Yun Su said, the others immediately followed suit and sat down to start practicing without asking any questions.

It has been more than four months since they came out, and they have been in the Wuyun Mountains for three months. Yun Su doesn't have much time left. He only asked his counselor for a year off from school. School will start in two months, so Yun Su must seize the time.

There was no end to the years and months of cultivation in the mountains. In the blink of an eye, more than a month had passed and everyone's cultivation had improved to some extent.

Opening his eyes, Yun Su's cultivation had reached the middle stage of the Golden Core. The spiritual energy in the air was no longer as dense as when he first came in, but it was still denser than outside.

With the help of the Spirit Gathering Array, the remaining spiritual energy is enough for others to practice.

Yun Su stood up and quickly swept the entire valley, leaving no magical herb untouched.

But it is certain that no other treasures were found, nor any inheritance, neither danger nor many good things.

The only things that satisfied Yun Su were these elixirs. All of them were thousands of years old, and there were even several that were ten thousand years old.

After coming back from the sweep, everyone else was still cultivating, only Jiang Biechen opened his eyes. This time his cultivation level was stable at the late stage of foundation building.

"I'm back." Jiang Biechen stood up, walked to Yun Su, reached out and touched Yun Su's cheek. Yun Su rubbed his palm in turn, looking so well-behaved.

"Yeah, I'm back. The whole valley is a secret realm. That's not quite right. It should be a secret realm of magical medicine. There's no danger in it, but there are no other opportunities, except for some magical medicines."

Jiang Biechen's eyes suddenly fell on Yun's hair, and he saw a butterfly resting there. This butterfly was very special, with half of its wings black and half white. Jiang Biechen had never seen this butterfly before.

He was sure that this strange butterfly suddenly appeared in Asu's hair.

Yun Su noticed that something was wrong with Jiang Biechen and asked in confusion, "What's wrong? Is there something on my head?"

Jiang Biechen nodded, "Well, there is a very strange butterfly, half of its wings are white and the lower half are black."
