With the closing of the gate, Chen Feng seemed to have come to a new world.

It's a field, a field as far as the eye can see. However, these fields are already barren at the moment, and standing on the ridges, Chen Feng can vaguely see the traces of the land that have been cultivated.

"These are all spiritual fields!" Chen Feng was surprised in his heart: "There are so many spiritual fields, could it be that this was once a huge elixir field?"

The spiritual field, which was specially opened up by the monks to grow the elixir, is very precious. In his previous life, Chen Feng owned thousands of acres of spiritual land. It was also the massive amount of elixir produced in these spiritual fields that made him finally hit the high realm of alchemy and became one of the five ancestors of cultivation.

However, the spiritual field that appeared in front of Chen Feng in front of him was endless, and at a glance, there was no end in sight. Suo Ran is empty and lifeless now, but Chen Feng can still imagine how prosperous this place was at the beginning.

Along the Lingtian, Chen Feng flew into the distance. According to the map in my mind, this spiritual field is only a peripheral area, and at the end of the spiritual field, there is a huge scale of buildings. In this unknown environment, Chen Feng was afraid of touching some organ prohibition, so he didn't dare to fly too fast. Half an hour later, Chen Feng finally came to the end of Lingtian.

At the end, a crystal clear stream remains, and the sound of the rushing stream is crisp and moving, like a beautiful music. Above the stream, a quaint stone bridge spans both banks, like a bent old man, each stone showing the sediment of time.

"I don't know how many years this secret realm has existed, but this stone bridge can still be preserved, which is also commendable. Chen Feng gently stroked the railing of the stone bridge, feeling the traces of the potholes eroded by the wind and rain, and said with admiration, and at the same time felt a faint sadness for the disappearance of this once extremely prosperous secret realm.

Passing along the small bridge, Chen Feng suddenly felt a tightness around his body, and a faint pressure suddenly acted on his body. Suddenly, Chen Feng was surprised to find that he couldn't fly.

"It seems that although so many years have passed, there is still a strong prohibition in this secret realm. After crossing the stone bridge, I entered the forbidden area, so I could no longer fly. Chen Feng didn't panic because of this, even in the cultivation realm, such a ban is very common.

All the way forward, Chen Feng came to a large complex of buildings.

"Presumably, this is the main complex on the map. Looking at the dense and continuous large buildings in front of him, Chen Feng thought in his heart: "Sure enough, as shown on the map, this complex of buildings is a labyrinth. If you don't know how to move, you're bound to die in it.

"However, wealth and wealth are in danger, I want to see, what are the secrets here?" Chen Feng did not hesitate, and entered the building complex with one step.

Just as Chen Feng had just entered the complex, an old voice suddenly remembered in his heart: "Collect one hundred and eight Ning Yuan Pills from the places marked on the map, and you can pass this level!"

"One hundred and eight Ning Yuan Pills?" Chen Feng wondered in his heart, and then, his mind was immersed in his mind again. This time, he was surprised to find that the map in his mind actually appeared with green dots. These green dots were located in various corners of the map, apparently marking the location of Ning Yuan Dan.

After carefully studying the location of the Green Dot Branch for a while, Chen Feng suddenly found that one of the Green Dot was in a house next to him.

Chen Feng cautiously pushed open the door of the house and walked in softly, taking every step very carefully. In such a secret realm, there may be some traps, so it's better to be careful.

It was an ordinary ancient dwelling, and despite the erosion of time, the room was still spotless. What interested Chen Feng was that in the center of the room, there was an alchemy furnace. After all, the alchemy furnace can't stop the erosion of time, and it has become dilapidated and spiritual.

"Could it be that the owner of this room used to be an alchemist?" Chen Feng thought in his heart, but his eyes carefully scanned everything in the room.

"There!" Chen Feng found that there was a jade bottle on the head of the bed by the window, and there was no need to think about it, the Ning Yuan Pill that Chen Feng was looking for should be inside.

Walking over, Chen Feng cautiously picked up the jade bottle, and was stunned again.

I saw that inside the jade bottle, there were five pills, five different kinds of pills.

"This is the Zhuji Dan, this is the Destruction Pill, this is the Pregnancy Spirit Pill, huh, there is even a Crossing Erjin Pill?" In an instant, Chen Feng became excited. Unexpectedly, in addition to Ning Yuan Dan, there were other pills in this jade bottle. Moreover, compared to other pills, Ning Yuan Pill is the most rubbish pill.

"Do you want to take it all?" Chen Feng hesitated in his heart, although he didn't care about these pills, he could give them to others.

However, soon, Chen Feng dismissed this decision. Such a powerful secret realm, if you can pass the level just by looking for Ning Yuan Dan, it will be too simple. So Chen Feng thinks that there must be a secret in this that he doesn't know.

So, Chen Feng just poured out Ning Yuan Dan, and then capped the jade bottle again and put it in its place.

"There's something wrong with this Ning Yuan Dan!" Chen Feng's heart moved, and he saw that this Ning Yuan Dan was emitting a faint blue light, if he didn't look closely, he would definitely not be able to notice it.

"It seems that the senior who designed this level has put a mark on every Ning Yuan Dan in order to prevent the occurrence of cheating!"

"I'm not cheating, though, so there's no need to be afraid. Let's go, go to the next room!" Chen Feng, who had collected a Ning Yuan Dan, had already left the room as soon as his body moved, and according to the map, he rushed towards another room marked with a green dot.

"Hey, there is an alchemy furnace in every room, is it ......" After entering more than ten rooms in a row, Chen Feng found that there was an alchemy furnace in each room, combined with the vast spiritual field outside, Chen Feng had a guess in his heart: "Could it be that this place used to be an alchemy sect, but later it suffered a catastrophe and completely declined?"

"Alas, why do you want to do so much, it's important to complete the task as soon as possible. After speaking, Chen Feng walked towards the jade bottle on the bed.

Sure enough, there were still five pills in the jade bottle, except for one Ning Yuan Pill, all of them were extremely precious.

However, the more this was the case, the more Chen Feng didn't dare to take it away, and he just honestly took out Ning Yuan Dan and left.

More than an hour later, Chen Feng closed a jade bottle in a room.

"The one hundred and eighth Ning Yuan Dan has finally arrived. I should have passed this level, right?" Chen Feng chuckled and his body disappeared from the room.

A moment later, Chen Feng came to a small square, which was the exit marked on the map.

"I've completed the task, but how do I submit it?" Chen Feng thought to himself, but his eyes kept looking around. However, even though Chen Feng swept every corner, he didn't find anything special.

"Not on the ground, is it in the sky?" Chen Feng raised his head suddenly, and the next moment, his expression froze.

I saw a huge eye staring straight at him in the blue sky.
