Due to the continuous infiltration of the first space by the Hidden Family, the world situation has become extremely tense.

However, the people's lives in China, which have been passed down for a long time, are still the same as before. When watching the news broadcast, I sighed that the world is still not peaceful.

Although Li Qingyu, who was not involved in these things, seemed to live a step-by-step life, a string in his heart was still tense, fearing that the people from the hidden family would penetrate into China again, which would be detrimental to his parents and relatives.

In order to ensure the safety of everyone, while strengthening their protection, Li Qingyu also constantly urged them to work hard and try to protect themselves.

Since he learned how to carve the formation, he has told everyone not to care about the consumption of the spirit crystal. After the spiritual energy in the spirit crystal is consumed, he will give it to him, and he will carve the formation on it, and then put it at the bottom of the Koi Lake in Jinjiaoda to replenish the spiritual energy.

After Li Qingyu reached the bottom of the lake several times, he found that the recovery speed of the spirit crystals in the stone cave at the bottom of the lake was very fast!

The spiritual crystal he put in for the first time was actually full of spiritual energy in just one week!

Zhou Xianguang once told him that the spiritual crystals on his side would take a month to fill with spiritual energy.

The difference between a week and a month is a bit big.

There are only two reasons for such a large difference in the "charge" speed. One is the spirit gathering formation hand-carved by Li Qingyu, which is different from the formation depicted by precision mechanically.

The second is that the concentration of spiritual energy in the two sides is different. Putting a sponge into heavy fog and in pouring rain, the water absorption rate is naturally different.

The spiritual crystals on Zhou Xianguang's side were charged on an isolated island in the East China Sea. Li Qingyu had also been there. He felt that the concentration of spiritual energy in Koi Lake was not as good as there. Why did the spiritual crystals on his side only take seven days to fill, but Zhou Xianguang's side took one month?

At this time, Li Qingyu had already had many spiritual crystals in his hands that had been used up by the Niu Family Women's Detachment, Lin Jingya, Xiaozhu, Liu Jiayi and others. He personally carved the spirit gathering formation, went to Beijing and handed it over to Zhou Xianguang.

After listening to Li Qingyu's report, Zhou Xianguang was also puzzled, so he sent the spiritual crystal sent by Li Qingyu to the isolated island in the East China Sea to recharge, and then handed a piece of spiritual crystal of the same size and carved the array base with precision instruments to Li Qingyu, so that Li Qingyu could replenish his spiritual energy in Koi Lake.

Comparing the two spiritual crystals, the result was soon obtained.

After the spirit crystal that Zhou Xianguang gave to Li Qingyu was placed in Koi Lake, it took ten days to be filled with spiritual energy. The spiritual crystal returned to its crystal clear and full of spiritual energy.

Ten days later than the spiritual crystals that Li Qingyu carved the spirit gathering formation, but it took much shorter time than the one that Li Qingyu personally carved the formation and then handed it to Zhou Xianguang.

That one took twenty-five days!

But it takes one month to place the spiritual crystals that use precision instruments to carve the formations on the isolated island of the East China Sea! Li Qingyu’s spiritual crystals that use hand-carved formations were shorter than five days.

Compared with the two, Li Qingyu and Zhou Xianguang quickly came to two conclusions:

First, the array base hand-carved by Li Qingyu is better than the array base carved by precision instruments. Because Li Qingyu's spiritual crystals that carved by the array base and the spiritual crystals that carved by the precision instruments, they are placed in the same place to replenish the spiritual energy. Always the spiritual crystals that carved by Li Qingyu's spiritual crystals that carved by the array base are charged first.

After confirming this, Zhou Xianguang was so shocked that he didn't recall the smell for a long time. He just wanted to say that the monster Li Qingyu is so evil! How stable is his hand? The array base he carved is more accurate than the array base he carved with precision instruments?

The second conclusion is that the concentration of spiritual energy at the bottom of Koi Lake is stronger than that of the spiritual crystals in the isolated island of the East China Sea! Because whether it is the spiritual crystals that are portrayed in precision instruments or the spiritual crystals that are portrayed in the array base by Li Qingyu, they are placed in two places, and the energy recharged on Koi Lake is always completed first!

Zhou Xianguang came to Jinhai City in person, and stood at the shore of Koi Lake with Li Qingyu at midnight.

The night is quiet, the street lights are gone, only the moonlight shines on the water of Koi Lake. The breeze blows, the waves are sparkling, and the surroundings are quiet, only the sounds of crickets and mole crickets occasionally sound.

While using his skills to greedily absorb the surrounding spiritual energy, Zhou Xianguang sighed: "Jinjiaoda is a place of crowds of people, and there are people coming and going on the shore of Koi Lake every day. There is actually spiritual energy here, and it is so rich, which is a miracle."

"It's really weird." Li Qingyu also raised his eyes and looked at the shimmering lake in front of him.

In the Dharma-Ending Age, there are very few places where there are spiritual energy on earth, and the only few are located in the mountains, forests, or small islands that are rarely visited. I didn’t expect that there are also rich spiritual energy in places like Koi Lake, which is indeed very strange.

"But the concentration of spiritual energy here is about the same as that of the small island in the East China Sea. Why is the speed of replenishing spiritual energy to spiritual crystals so different?" Li Qingyu continued.

"Let's go under the water and take a look. We'll stare at it all night and maybe we'll find it." Zhou Xianguang said.

Li Qingyu nodded and took Zhou Xianguang to a hidden place, dived into the water, and headed straight to the small cave at the bottom of the lake.

After approaching the small cave, the two of them clearly felt that the spiritual energy here was stronger than the shore, but the difference was not very big. The two of them concluded that there must be a secret here.

The two of them walked around the hill at the bottom of the lake for a long time, trying to find something unique, but they never found anything.

After more than thirty minutes, Zhou Xianguang felt that he could not hold on at the bottom of the water anymore. He went to the water to change his breath and then dived into the bottom of the water to continue researching.

Half an hour later, a miracle happened!

They saw that the small cave where Li Qingyu placed the spirit crystals, there was a white light shining out!

It seemed like an electric light was lit in the cave.

Li Qingyu and Zhou Xianguang couldn't help but look at each other, and their eyes were full of doubts!

"What the hell?" Li Qingyu couldn't help asking.

To him and Zhou Xianguang, speaking underwater is nothing.

Zhou Xianguang shook his head and said, "I don't know, go in and take a look."

The two of them swam with their arms, swimming to the entrance of the small cave like two big fish, but they lay at the entrance of the cave without anyone coming in, but they just turned their eyes into it.

The water in Koi Lake is very clear and cannot hinder their sight at all.

They were surprised to find that the light actually came from the stone wall at the end of the small cave!

The small cave is only more than two meters deep, and the end of the cave turned out to be an ordinary stone wall. If you have any special features, it is just that it is smoother by the water flow.

Now the stone wall actually emits a white light!

What's even more strange is that the stone wall at the end of the cave seemed to have turned into a curtain blown by the wind, constantly swaying.

At the same time, the two of them could clearly feel that the spiritual energy in the cave suddenly became richer, as if as the stone wall "wavered" it, the spiritual energy spread out from behind the stone wall.

"What's going on?"

Li Qingyu was puzzled. He kicked his legs and wanted to enter the stone cave. He went over and touched the swaying stone wall, but was pulled by Zhou Xianguang beside him.

"Don't move!" Zhou Xianguang said.

Li Qingyu turned around and saw Zhou Xianguang's serious face, and at the same time, he was swaming at a few small fish as big as a palm, which was obviously attracted by the strange light.

Li Qingyu and Zhou Xianguang remained motionless, like stone sculptures, trying not to disturb a few small fish.

Several little fish directly regarded Li Qingyu and Zhou Xianguang as rocks, and did not dodge at all. They swam past their faces, entered the cave, and headed straight for the strange stone wall...
