With Ye Feng's cultivation comparable to Yuan Wu's triple cultivation, with the help of Ye Ning and Chen Xiaoice, it was easy to clean up the remaining two.

After killing all the three gatekeepers, Ye Feng took Ye Ning and the others directly into the stone tower.

Some luggage was piled up in the stone tower, Ye Feng snorted coldly, took out his sword to break the luggage, and found that it was full of supplies such as dry food and water bags.

"Ning Hong's people, obviously use this stone tower as a base camp, they think that only three Yuan Martial Realm martial artists can keep these things, it's really ridiculous!"

Ye Feng didn't say a word, cut all the water bags, and finally lit a fire to burn all the dry food accumulated by the Ning family.

Ye Ning had just killed someone, and his eyes were a little dull at the moment, while Chen Xiaoice was watching Ye Feng's actions with trepidation on the side, not knowing what he was thinking.

Ye Feng glanced at Ye Ning, and said secretly in his heart: "With Ning'er's temperament, I'm afraid it will take a while to adapt to killing, it seems that it is the right time to bring her here this time." After this experience, after returning to the family, Ning'er will grow a lot!"

After burning the luggage, Ye Feng cleaned up the remnants of the ground, searched carefully, and with the help of his spiritual sense, he soon discovered the abnormality on the ground of the stone tower.

After simply pouring it with clean water, a huge cyan stone block on the ground attracted the attention of the three people.

The stone is carved with some strangely shaped characters, and in the center of the stone, there is a slightly raised beast head, which is carved from bronze, lifelike, like a lion and a tiger.

An iron ring was set in the open mouth of the bronze beast's head.

Ye Feng pondered for a moment, then stretched out his hand and pulled towards the iron ring.

"Boom!" Under Ye Feng's strength of 1,700 catties, the huge bluestone block was slowly pulled up by him.

Underneath the bluestone block is a cave about a zhang wide, with a rotating stone staircase that winds down at the entrance.

"Although there are many dangers inside, you will be fine if you follow me!" Ye Feng has the powerful sensing ability of an immortal cultivator, and he is not worried about the danger that may exist in the underground ancient city.

The two girls nodded in unison and followed Ye Feng into the cave.

It was pitch black in front of them, and there was a rancid and unpleasant smell around them, although Ye Ning and Chen Xiaoice had cultivated well, they were girls who had not yet reached adulthood after all, and they couldn't help but be afraid in the face of this environment.

"Don't be afraid!" Ye Feng's footsteps were low and powerful, there was no fear on his face, in front of the immortal cultivator's inductive power, there was nowhere to hide any danger in the dark.

Ye Ning and Chen Xiaoice were infected by Ye Feng, and their mood relaxed a lot, and they followed closely behind Ye Feng.

After a long time, Ye Feng's footsteps suddenly changed.

"Finally reached the ground!" Ye Ning and Chen Xiaoice breathed a sigh of relief.

Ye Feng used the spiritual power in the dantian in his eyes, and under the shroud of darkness, his eyesight was not affected at all, and he could easily grasp the surrounding environment.

Where they were, it was a very desolate open area, with soft, damp earth beneath their feet and stone walls covered with green moss.

"Brother Ye Feng!" Ye Ning smelled Ye Feng's scent and leaned over obediently.

Chen Xiaoice took out a fire fold from his arms and lit it.

By the faint light of the fire, the two daughters saw their surroundings clearly.

"Let's go, it should still be on the periphery of the underground ancient city now, and when you enter the underground ancient city, there will definitely be many traps, and you will be fine if you follow me!" Ye Feng turned around and said a word to the two of them, and then took a step forward.

After walking for half an hour, the three of them came to stand in front of a dark gray earthen wall, which had no door, only a circular gap, about half a man high, as if it had been broken by man.

Ye Feng frowned slightly, glanced at the sewage that kept dripping from the gap, and drilled into the hole.

The second girl covered her nose and followed with some reluctance.

"Whoosh!" There were two sounds in front of her, and the second girl's heart suddenly became nervous, the hole was narrow at the moment, and there was no place to hide.

"Ding, ding!" was two more crunching sounds, and the sound of a heavy object falling to the ground.

"Brother Ye Feng!" Ye Ning exclaimed in a low voice, thinking that there was some danger ahead.

"It's okay, a little trick has been broken by me, you come directly, but don't enter the hall. Ye Feng's words came from the front, and the two of them were relieved and quickly followed.

There were two sharp spears on the ground, and Ye Feng stood in a spacious hall, looking down at the circular pattern on the ground, as if he was pondering something.

"The Five Elements of Yin and Yang...... Qimen Dunjia...... How can these things also exist in this continent, doesn't this belong to immortal cultivators?" Ye Feng stared at the ground intently, and said something that Ye Ning and Chen Xiaoice couldn't understand.

"What's wrong?" Ye Ning asked in a low voice as she stood outside the hall.

"It's nothing, there's no road ahead, but there's a mechanism here, I'm trying to crack it, don't lean over, it may be dangerous!" Ye Feng said without looking back.

"Okay, then we'll wait for you at the door!" Ye Ning nodded obediently and agreed.

"Brother Ye seems to be somewhat familiar with this place, has he been here before?" Chen Xiaoice looked at Ye Feng in the distance and said to Ye Ning in a low voice.

"How is that possible?" Ye Ning shook his head like a drum, and said seriously, "The Silver Moon Secret Realm was opened once fifty years ago, and Brother Ye Feng hadn't been born yet!"

Chen Xiaoice nodded, looking at Ye Feng, who had been muttering something in a low voice, and was speechless for a long time.

In two months, from the fourfold broken vein waste of strength and martial arts, he has grown into a powerful and mysterious master of the Yuan Martial Realm, what has happened in this?

The mysterious aura on Ye Feng's body had an irresistible allure to Chen Xiaoice.

"This picture is like the prototype of the Tai Chi Bagua Array, but it only shows the truth of the five elements of mutual restraint, and does not involve the mutual birth of the five elements, it is extremely simple to crack, I thought too much about it before, and regarded it as a maze laid by a certain immortal cultivator!"

Ye Feng studied it for a long time, and finally let out a sigh, this hall, he had a strong sense of familiarity as soon as he entered, and only after taking a few steps and touching some simple mechanisms hidden underground, did he know that he seemed to have broken into some kind of maze.

However, this kind of maze, compared to the strong ** array of the immortal cultivator world, is really simple and rough to the extreme, Ye Feng thought too much about it at first, but thought that the maze in this hall was playing tricks.

The circle is divided into five sections, each with a large number of quirky texts in the center, and a very abstract picture is drawn.

In the area symbolizing "fire", the picture is a roaring bonfire.

In the area that symbolizes "earth", it becomes a majestic mountain.

According to the principle of the five elements, Ye Feng suddenly got up and took seven simple steps in the ring.

In just seven steps, the maze was easily cracked by Ye Feng.

There was a sudden jolt on the floor of the hall, and then the middle part of the circle was dented, and a stone pillar protruded from the depression.

"The formation map is sparsely done, but the mechanism is not bad, and I don't know what it is used as the driving force!" Ye Feng pursed his lips with some disdain, and his eyes were fixed on a red wooden box on the stone pillar.

"Come in!" Ye Feng shouted at the second daughter outside the hall, and unceremoniously put the wooden box in his hand!

The second daughter was already deeply shocked by the scene that appeared in front of her, and when she heard Ye Feng's call, she hurriedly rushed over.

"What was it just now, brother, did you break any mechanism again?" Ye Ning looked at the wooden box in Ye Feng's hand curiously.

"Well, it's just a very simple mechanism, I didn't expect there to be a reward!" Ye Feng nodded with a smile and opened the wooden box in his hand.

A refreshing medicinal fragrance enveloped the entire hall, and Chen Xiaoice's heart shook violently, and he looked at the wooden box in Ye Feng's hand with an incredible face.

"Gathering ...... Ju Yuan Dan, it's actually Ju Yuan Dan!"

There are ten crimson pills in the wooden box!

"Ten Juyuan Pills!" Ye Ning also said in a trembling voice with a slight change in his face.

"Is it really Ju Yuan Dan?" Ye Feng asked with some excitement and some suspicion, he had always used Ning Yuan Dan before, and he had never seen Ju Yuan Dan's appearance.

"It won't be wrong, it's the Juyuan Dan that the Yuanwu Realm martial artists dream of!" Chen Xiaoice nodded again and again, and said, "When I broke through to the Yuanwu Realm, my grandfather gave a Juyuan Pill as a reward, and I have been reluctant to use this Juyuan Pill now!"

After speaking, Chen Xiaoice took out a jade vial from his arms and poured out a crimson pill from the bottle.

The shape, fragrance, and color are almost exactly the same as the Juyuan Dan in Ye Feng's hand.

"I didn't expect it to be Ju Yuan Dan, I am now a Yuan Martial Realm Heavy, the ordinary Ning Yuan Pill is no longer of any help to my cultivation, only Ju Yuan Dan can allow me to break through to the Double Realm!" Ye Feng was overjoyed in his heart, these ten Ju Yuan Pills were exactly the treasures he urgently needed now.

"Miss Chen, since you have so many Juyuan Dan in your hand, you won't be reluctant to use up the Juyuan Dan in your hand, I'll give you two first, if it's not enough, you can continue to look for me!" Ye Feng took out two Juyuan Dan and handed them over directly.

"This ...... I'm afraid this is not very good, my life was saved by you, and I must have been busy until now!" Chen Xiaoice's face was slightly red, and her dark pupils were shrouded in a cloud of mist.

Ye Feng's generosity touched her again.

Ye Feng smiled, directly stuffed the Juyuan Pill into Chen Xiaoice's hand, and said sincerely: "When we were in the ruins just now, if it weren't for your help, we wouldn't have come to this place so smoothly, and I wouldn't have been able to get these ten Juyuan Pills!"

"Yes, Sister Xiaoice, you can take it!" Ye Ning also interjected on the side.

The warm feeling coming from Ye Feng's hand made Chen Xiaoice's little face blush like an apple, but fortunately, it was covered by the fire on the fire fold, and Ye Feng and Ye Ning did not notice the change in her expression.

"Without further ado, let's cultivate here!" Ye Feng slowly walked to the earthen wall in front of him, and the tide palm suddenly burst out.

"Bang bang bang!" the earthen wall collapsed, obscuring the entrance to the hall entirely.

"Ning'er, you are responsible for guarding, if there is any disturbance outside, you must remember to wake us up!" Ye Feng commanded Ye Ning in a low voice.

Ye Ning naturally agreed without hesitation, she had just broken through and was still consolidating her cultivation, so there was no need to continue her cultivation, and the medicinal power of Juyuan Dan was not something that the meridians of the martial arts realm could withstand.

There were a few oil lamps on the wall of the hall, and Chen Xiaoice carefully lit the oil lamps, said hello to Ye Feng and Ye Ning, and first found a fairly clean corner and practiced cross-legged.

Ye Feng sat directly in the middle of the stone pillar, calmed down, and put the wooden box he had just obtained in front of him.

"There are still eight Juyuan Pills, I don't know how many I need to break through to the Yuanwu Realm Duplex, but the number is definitely more than ordinary people!"

He didn't know that ordinary people broke through from the first level of the Yuanwu realm to the second realm, and one Juyuan Pill was more than enough, and even some Lang Fei, the reason why Chen Xiaoice had been reluctant to swallow that Juyuan Pill was because he was reluctant to swallow the medicinal power of Lang Fei Juyuan Dan.
