"Boss, this green-eyed thunder lion meat is really good, it is worthy of being at the level of a holy beast."

In Black Stone City, Li Lao Er grabbed a skewer of huge barbecue and ate it so happily, his mouth was full of oil, and his appearance was as slutty as it was.

A day has passed since the death of the Qingmu Lei Lion. With the death of the Qingmu Lei Lion, the group of monsters has completely dispersed.

As for Ye Chen, he ignored Li Jianli. While eating barbecue, he lowered his head and thought about something.

"Boss, the formation has been arranged. Do we want to stay here forever?" Zhuge Lianying came back from a distance, tore off a large piece of lion meat, and took a bite.

Zhuge Lianying's words woke Ye Chen up, then looked at everyone blankly and answered the question: "You don't feel that Black Stone City is different from other places."

"The spiritual energy here is stronger. No, to be precise, it is easier to comprehend the power of heaven and earth." Zishang expressed his thoughts without thinking.

"It's true." Li Jianli closed his eyes and felt it for a while, and said in surprise as if he had discovered a new world.

Everyone looked at Li Jianli with contempt, and Yu Linglong said again: "No wonder the powerful people in the Tianling Realm want to come to the battlefield of all spirits. It is obviously related to the easier it is to understand the power of heaven and earth here."

"This is just one of them." Ye Chen nodded and shook his head again: "There is more than one city on this battlefield of all spirits. If Black Stone City can more easily comprehend the power of heaven and earth, what about other cities? Those monsters desperately attacked the major cities, it shouldn't be for no reason."

"Other cities can do it too?" Everyone's eyes lit up and their expressions were excited.

"Yes, Black Stone City can speed up our understanding of the power of heaven and earth, and it is twice as high as other places. So can we guess that some cities can understand the power of heaven and earth faster?" Ye Chen nodded deeply.

Obviously, Ye Chen's meaning is very obvious. He cannot be satisfied with a small black stone city. He must continue to go deep into the battlefield of all spirits.

As for why Black Stone City can easily comprehend the power of heaven and earth, Ye Chen is not very clear about this, but he has already made a decision in his mind, that is, to dig three feet into the ground and make Black Stone City understand.

It was night, and Black Stone City was swallowed by the darkness again. But strangely, there was no tide of monsters coming tonight, which shocked Li Lao Er and the others. I think those monsters were afraid of being killed by Ye Chen.

Zhuge Lianchang opened the city protection formation, and then everyone entered into meditation and began to practice.

Only Ye Chen used the earth escape technique and sneaked into the depths of the Black Stone City. He wanted to figure out what the difference is in this Black Stone City.

In terms of geographical location, Blackstone City is not very superior. It is built on the hillside. In terms of defense ability, without a city moat array, Blackstone City's defense is obviously particularly weak.

However, this Black Stone City happened to be built here. The strangest thing is that even in a place separated by a wall, there is a big gap in the speed of cultivation.

Even Ye Chen didn't know what the black stone was. You must know that with Ye Chen's eyesight, there were very few things he had never seen before.

"Nothing is different." Ye Chen sneaked to a depth of 100 feet underground and did not find anything wrong. Could it be that he was thinking too much?

Ye Chen shook his head. If something goes wrong, there will be a demon. He feels that Black Stone City is definitely not as simple as he imagined, and it must have its secrets.

He sneaked for another two hundred feet and searched every inch of land under Black Stone City, but still found nothing. Ye Chen couldn't help but feel a little disappointed.

Even so, he still did not give up. Another hour passed by, and Ye Chen was a little troubled to use the earth escape technique. This would consume physical strength and mind more than a battle.

"Is it in the air not underground?" Ye Chen frowned. With his strength, he could still hold on for half an hour. If he couldn't find it again, he could only give up for the time being.

Then, Ye Chen closed his eyes and quietly felt the changes around him. After a while, Ye Chen suddenly opened his eyes and said in surprise: "No, the power of heaven and earth here is more intense and easier to understand! That can only tell one thing, the secret is still below!"

Ye Chen took a deep breath, then stopped hesitating, and continued to move forward by using the earth escape technique. This time, they explored the four directions, but after a period of time, they felt the changes in the power of heaven and earth.

After almost half a cup of tea, Ye Chen had already arrived hundreds of feet deep underground, and his figure slowly stopped.

Below, a strong breath came to my face. After taking a breath, Ye Chen felt comfortable all over, and all his pores opened freely, opening and closing were very rhythmic.

"Is that?" Ye Chen's figure trembled a little, and in an instant, he took a step out.

A gorgeous small space entered Ye Chen's eyes. The space was not big, only one meter in a circle, but what attracted Ye Chen was the shining crystals embedded on the surrounding cliff walls.

The crystal stones are colorful, extremely gorgeous, surrounded by mist, making people unreal, but Ye Chen recognized these crystal stones at a glance.

"Heaven and Earth Soul Crystal! No wonder it makes people more likely to understand the power of heaven and earth." Ye Chen took a deep breath and forced himself to calm down.

The soul crystal of heaven and earth is the product of the power of heaven and earth. It is one of the holy crystals. It is of extremely precious value. It can be directly refined into the power of heaven and earth and absorbed and melted by the monks. When it reaches a certain level, it can be directly realm.

Based on this alone, we can guess the value of the soul crystal of the heaven and earth.

However, it also has its own disadvantages, that is, it is to melt the soul crystal of heaven and earth to break through. It is extremely difficult to break through the Holy Spirit Realm.

The reason for this is very simple, that is, the melted power of heaven and earth is far less profound than that of one's own understanding. The Holy Spirit Realm is to control the power of heaven and earth. If the understanding is not thorough, how easy is it to control it?

Of course, everything is absolutely absolutely true, and it is not impossible to become a powerful person in the Holy Spirit Realm if the cultivator has a deep understanding of the power of heaven and earth, and at critical moments, he can still melt the soul crystal of heaven and earth to break through.

Only perverts like Ye Chen can sneak into the ground hundreds of feet before they can discover the secrets of Black Stone City. Otherwise, the secrets of major cities will become eternal mystery.

Looking at the Heaven and Earth Soul Crystal above the cliff, Ye Chen felt a little embarrassed. If he took the Heaven and Earth Soul Crystal directly, the cultivation effect of Black Stone City would inevitably be greatly reduced, but if he didn't take it away, Ye Chen felt sorry for him again.

With the strength of Ye Demon King, he naturally does not have to directly melt the Heaven and Earth Soul Crystal. He can use the Heaven and Earth Soul Crystal to arrange magic arrays to facilitate his own cultivation. In this way, the effect of comprehension of the power of heaven and earth is definitely not comparable to that of Black Stone City.

"If you don't take it, you will suffer the consequences. If you get it, you will take half of it." Ye Chen comforted himself, and then he stuffed the soul crystals of heaven and earth into the space ring by him, and he was very busy.
