"Oh my God, it smells so good. Martin exclaimed, although she didn't know these elixirs, she also knew that they were definitely not ordinary medicinal materials.

"Haha, I haven't been able to find enough elixir to refine the elixir, but I didn't expect it to take no effort to get it. Chen Fengyun was also overjoyed, and immediately began to dig up the elixir, digging it up along with the soil below, and sending it to the miniature cave sky.

After Chen Fengyun's cultivation broke through to the Jindan period, the miniature cave had reached the size of ten square kilometers, although it was not as big as this Wangwu cave, but it was almost the same as the previous Taojia Taoyuan Cave.

It's just that Chen Fengyun hasn't tried to put some life in the cave sky, but there is enough place to cultivate all kinds of elixirs, but it is not easy to collect elixirs in the outside world, and now there are only twenty or thirty kinds of elixirs in Chen Fengyun's miniature cave.

But in this elixir hall, after Chen Fengyun's divine sense scanned, he found that there were more than 100 kinds of elixirs, and in addition to the duplicates that were the same as his own, there were more than 90 kinds that he didn't have.

Although these elixirs are relatively ordinary, they are enough to refine the two kinds of pills that can be used by martial artists, Xiao Pei Yuan Dan and Pei Yuan Dan, and even most of the medicinal materials for refining Jing Yuan Dan are available, only one or two medicinal materials are missing.

"I'll help you too. ”

Martin didn't have any thoughts about these elixirs, she knew that Chen Fengyun had a miniature cave, so she immediately came up to help him dig up all kinds of elixirs, and even dug up the whole land with her.

It took two hours, with the help of Martin Dang, Chen Fengyun excavated a total of thousands of elixirs, although these elixirs grew slowly due to the lack of aura, and some elixirs were not strong enough, but after transplanting them into the miniature cave sky, there was enough auras for them to grow.

Among them, there were thousands of mature elixirs, and Chen Fengyun collected the rest except for one of each elixir to use as seeds, so as not to occupy more land and be more conducive to the growth of other elixirs.

Chen Fengyun had already harvested hundreds of mature elixirs, and after he was ready to leave Wangwu Mountain, he returned to the capital university and began refining pills, although his pill medicine skills had reached the initial level of the Xuan level, but he had not really refined the pills.

As before, except for the elixir planted in the courtyard, there was nothing left in the building, and these elixirs were also some medicinal seedlings left sporadically when the Wangwu faction was relocated, and the seeds that had grown and sown over thousands of years had grown.

Then, in the next training hall, trial hall and other places, the two of them did not find anything, so they went to the third palace at the back, but when they reached the back of the mountainside, they found that there was only a nine-story glazed tower in front of them, and there were no other buildings.

"In Xia Chen Fengyun, I came to visit the seniors of the Wangwu faction, and invited the seniors to show up. ”

Chen Fengyun stepped forward to probe the tower with his divine sense, but found that his divine sense could not enter the tower, and he didn't know the situation in the tower at all, so he shouted loudly to the tower.

However, no one answered, and after waiting for a while, he took Martin carefully into the bottom of the tower and slowly explored the situation in the tower.

As soon as the two of them entered the tower, they immediately felt a sense of rotation, and then found that they found a huge space, surrounded by a vast yellow sand, as if they had arrived in a desert.

"Be careful. Suddenly, Chen Fengyun made a discovery, and immediately pulled Martin, and the two of them rose up with their swords and flew into the air.

Then, I saw that the desert ground shook for a while, moving violently like a wave, and insects formed by yellow sand drilled out of the desert, each of which had the strength of the early stage of foundation building.

"It seems that this tower is also a magic weapon, and it has its own realm inside, which can form a variety of different forms of attack. "Chen Fengyun is also proficient in formations, and he can see the problem in an instant.

Just as he spoke, the sandworms pounced into the air, trying to strangle the two, but both of them were strong, and they could blow up one by one with just ordinary shots.

"You have to find the core formation base of the Yellow Sand Formation before you can enter the next layer. Chen Fengyun took Martin to blow up the sandworms one by one, while moving in mid-air, and soon found a huge hill in the center of the desert, and immediately flew over.

However, as soon as the two of them arrived in front of the sand dune, the sand dunes actually stood up, but it was a sand man more than ten meters tall, and the aura emanating from his body had the strength of the middle stage of foundation building.

"The core formation base is in the body of this sandman, as long as you blow it up, you can control the core formation base, and then enter the second layer. Chen Fengyun laughed, and the Xuanyin Mirror emitted a cold breath of Xuanyin, which instantly froze the sandman, and then was blown up by him with one blow, and sure enough, he found a golden stone.

Chen Fengyun grabbed the golden stone and quickly refined it, and then the entire yellow sand space was quiet, and countless sandworms decomposed into yellow sand and scattered all over the ground.

At this moment, a pillar of light appeared above the huge sand dune, and Chen Fengyun took Martin into the pillar of light, his body disappeared, and then appeared in the vast water.

This water area is actually not large, but it is more than ten miles in size, there is no sign of life in it, there are no islands or anything like that, and there is a hazy mist floating on the water surface.

"Fengyun, is there something in this water attacking us?" Martin asked with some concern, looking at the vast water.

"There must be, you see, here they are. ”

Just as Chen Fengyun nodded, the surface of the water stirred, and then water beasts were formed, such as sharks, whales, octopuses, dinosaurs and other giant beasts in the water, all formed from water, and leaped towards the two people in mid-air.

However, the strength of these water beasts was only a little stronger than the previous sand worms, and they did not reach the middle level of foundation building, and they were easily defeated by the two of them, but the water beasts were endless, and more water beasts were formed after the defeat.

Chen Fengyun was also dual-minded, while protecting Martin Dang to defeat all kinds of water beasts, while observing and looking for the core formation base of this black water array, he soon discovered that it was a huge water dragon, the body size exceeded that of other water beasts, three times that of them, and the aura on his body was close to the late stage of foundation building.

"Boom ......"

Chen Fengyun flew directly over, waved his palm and slapped it down, the huge spiritual power surged, instantly defeated the huge water dragon, and then grabbed a drop of blue water from mid-air, and controlled the black water array after refining, and then it was rumored that the passage appeared, and the two teleported to the forest.

This is the third layer of the nine-story pagoda, and the formation here is called the Giant Wood Formation, and all the plants in the forest are derived from the formation, and then they transform into tree people, vine people, cannibal flowers, etc., to attack the two of them.

Soon, Chen Fengyun found a giant tree in the middle of the forest, whose strength reached the late stage of foundation building, and was killed by him, leaving a small sapling, which was the core formation base of the giant wood array.
