In addition to the internal exercises, the intensity of the vitality of heaven and earth also affects the efficiency of transforming the vitality into internal force, and every improvement in efficiency will make a huge difference in the volume of internal force over time, which is why Wang Shixian was ecstatic when he found that "Alchemy" could improve the efficiency of internal force cultivation.

Take Quan Zhen as an example, it is hidden in the mountains of the coastal mountains of northern Jiangsu Province, although it is dilapidated, but it still firmly guards the retreat cave dug in his backyard.

Internal force is the foundation of all cultivators' martial arts to exert great power, there is no internal force as a power output, relying solely on the biological energy in the human body to drive a strong physical body, although it also has good combat power, but it is really weak in comparison! And no matter how much food you eat, there is an upper limit to the total amount, but the internal force is different, it can continue to expand the capacity of the dantian when the dantian is full, when the dantian capacity is expanded to the upper limit, the internal force will gradually condense, and finally turn the real into the virtual, straight to the sea of knowledge, in the sea of knowledge and the spiritual power that has also reached a certain standard to integrate, and shape the primordial spirit! Achieve the supreme avenue! This is the most traditional and difficult road! In the entire history of China, there are only a few great people who can do it! And Han Li through the "Alchemy Technique" , relying on strong spiritual power to achieve enlightenment, it was really too tricky, and it also caused his foundation to be unstable, and he was successfully attacked by extraterritorial heavenly demons, and finally trapped in the barrier of time and space.

Of course, Wang Shixian now has a small Yuan Shen, and he may no longer need the internal force to meet the standard, as long as he has enough spiritual power to feed the little Yuan Shen to grow, but who would think that the internal force is strong? The key is that the Heaven and Earth Yuan Qi inside this Luding Mountain is unusually rich! For example, the retreat cave that belonged to the Emei Sect in the Qing Dao Courtyard of Xiyu Mountain, where Wang Shixian was in retreat before, was already a rare cultivation holy place in the world, but the concentration of Heaven and Earth Yuan Qi here was more than ten times that of Xiyu Mountain!

For a while, the eyes of the cultivators who found the abnormality flashed with eager eyes, if they could open a retreat cave here, not to mention ordinary cultivation, even if they could come here to retreat when they broke through the bottleneck, they could greatly increase the chance of breaking through the bottleneck!

"When the sky is reversed, it is a disaster, and things are a demon", Wang Shixian was excited and uneasy at the same time.

Suddenly, where Ray-Ban was, there was a low shout, and the screen of the robot's control platform flashed a few times, and then completely blackened.

"Is it too far away?" someone asked in a low voice.

"No, it's strong electromagnetic interference. The scout operating the platform replied.

"Let's go! Now it's up to us. Ray-Ban stood up and gave the order.

The stalactites in the passage on the left are clearly cleaned.

Seeing that he was about to enter the left passage, Qin Yumeng, who was walking in front, suddenly flashed and appeared in front of a pile of stalactites in the middle of the two passages.

Wang Shixian looked at it fixedly, and he also saw that something was wrong, there was a long black stone in the middle of this pile of stalactites! The stone was by no means a natural shape, and there were traces of rough polishing, like a stele! Wang Shixian leaned over, Qin Yu stared at the stone blindfolded, stretched out his hand and touched it, the surface of the stone had been cleaned, and the artificially carved lines with a great sense of history were revealed on it.

Seeing that the cultivators were moving, Ray-Ban stopped the advancing team, asked the team to maintain a defensive formation, and walked over with a few people.

"Did you find anything?" asked Ray-Ban, holding up the torch from his gun and striking the light on the rock.

"It's a painting. Qin Yumeng said calmly, his voice was full of magnetism, like flowing water through everyone's hearts. Qin Yumeng's sword heart was clear in this extremely rich heaven and earth vitality, and the effect of this extremely rich heaven and earth vitality actually increased significantly, and Wang Shixian listened to Qin Yumeng's words for the first time, and his mind was almost affected by her.

Everyone's eyes involuntarily stared at Qin Yumeng, quietly waiting for her next words.

"Humanoid. Qin Yumeng said while touching the stones: "There are many people, the heads are very big, and there is a big circle next to the crowd. ”

Wang Shixian said: "Luding Mountain ancient stone carvings?"

"Well, this should be the ancient ruins found by the previous expedition, you see that this pile of stalactites is not scattered and naturally generated, but lined up in a strange formation, these were also on the "Nature Weekly" back then. Sun Chuanyu pointed to the stalactites next to him and said.

Wang Shixian glanced at the stalactites, the nine roots, and took a closer look, they did have a boundary with other stalactites, and they were self-contained, forming a formation around the black stones.

Wang Shixian couldn't see any information, and he also touched the black stone with his hand, and started to warm it, he couldn't help but use his fingers to secretly use the internal force, and wanted to test the hardness of the stone, but he didn't expect it to sink into the sea like a stone, and the internal force disappeared into the stone.

Wang Shixian remained silent, withdrew his fingers, looked up and saw Qin Yumeng's two deep eyes looking at him, Wang Shixian smiled slightly, and Qin Yumeng turned around and left.

The team continued to move forward, but Wang Shixian had already thought about the black stone, thinking about how to smuggle the black stone back to China after the operation was over.

Although the passage in the cave is not very wide, it can also allow the two of them to walk side by side, which is much stronger than the crack outside. After walking for a while, they heard the sound of the wind, and everyone looked at each other and quickened the pace of action.

The wind grew louder and louder, and suddenly the scout walking in front stopped, "No way!" The scout's surprised voice came from the headset.

The road was really gone, and it came to an abrupt halt under the feet! There was nothing in front of it, and the flashlight was swallowed up and down by ...... left and right to the past.
