Although it snowed, the color of the mountains was not completely white, and a bare mountain wall a few miles to the right had the colorful lines of the sky, like a colorful oil painting with rich colors, unfolding towards the canyon in the distance. The snow only hides the canopy and the mountaintops, but exposes the trees, hot springs, and cliffs, making the contrast of orange, dark green, deep daisy, turquoise, and other colors even more intense.

Cheng Tianle watched the trajectory of the drop of water falling to the ground in silence, and clearly heard the sound of the water droplets splashing in the ashes and dust. Not far away, there was a boiling roar at the bottom of the lake, and then a column of water erupted in the rolling waves, rushing into the air more than ten meters away with a whistling sound.

This is a common geyser in Yellowstone, and this one is still small, and in some places the geyser erupts like an upside-down waterfall, and the sudden roar can be heard from afar. When the geyser was finished, the bay of hot blue water was still rippling, and Cheng Tianle looked into the distance at the wider valley, which was dotted with lakes of all sizes.

They came to find the Heart Essence Flame, but they did not take the Heart Essence Flame as their only goal, and it was also a practice to enjoy the scenery of the mountains and rivers along the way and to comprehend the spiritual breath of heaven and earth. Cheng Tianle said: "Yellowstone Park is so big, Bai Shaoliu gave me a coordinate, compared to the terrain here, if we walk through it at this speed, I'm afraid it will take a day or two." But as soon as I entered here, I had a very special feeling that the so-called Heart Flame may not be in that place. ”

Xiao Shao said thoughtfully: "I have watched this geyser erupt more than a dozen times, and I have also sensed the changes in the spiritual breath of heaven and earth. The mountains and rivers we walked through have geothermal activity, and there are huge geothermal currents deep in the underground in this area, and on the surface we see these hot springs and active volcanoes, but there is an invisible rhythm in the spiritual breath of heaven and earth.

Cheng Tianle nodded and said, "I also sensed it in the fixed realm, it seems to be able to resonate with the divine qi and enter a strange state. It enables people to touch a source in the nature of heaven and earth. The magic spell we perform is not so much a force as a change, controlling all kinds of energy and leading to changes. ”

When a monk experiences the Dan Fire Tribulation, his ordinary perception becomes very sensitive, even excessively sensitive. It is very easy to be stimulated by the environment, and the slightest carelessness when the spirit is running will lead to the so-called fire. Among them, the fire to be mastered is the purity of the mind, and the heart should be subtle. The essence qi they have obtained is the source breath of vitality, then this heart essence flame. It seems to be a kind of energy rhythm of life running, and I am afraid that it can only be obtained in a similar way as refining the essence qi.

The two of them had already realized that the Heart Flame was not a kind of heavenly treasure buried in the ground waiting for them to dig up, but a trace of origin spiritual breath that permeated this heaven and earth. They first have to resonate with it. Only then can the primordial spirit refining be carried out in the fixed realm to take that wisp of heart essence flame, it seems to be out of nothing like the essence of the qi, but it is indeed in the spiritual breath of heaven and earth.

This is no ordinary effort. The world that needs to be unfolded is wide and clear enough to be compatible with the interior and exterior scenes. in order to resonate with the rhythm of this snow-capped mountains and rivers. The reason why Cheng Tianle can try this way and have this kind of induction is also related to his cultivation experience. His Yuanshen world unfolded, which could completely and clearly accommodate the Gusu City in the picture scroll. If it weren't for that, he wouldn't have been able to refine that scroll of artifact and finally bring Xiao Shao to this world.

Xiao Shao said again: "The location that Bai Shaoliu is referring to should be the central location of this strange heaven and earth spiritual breath, where you can successfully harvest the heart flame. ”

Cheng Tianle: "I also learned a lot from Melander, looking at the topography of this mountain and river. The place where Bai Shaoliu pointed should also be where the spiritual eye of the earth is. …… How are you feeling here, can we move on? ”

Xiao Shao smiled slightly: "It's almost over, let's continue to move forward." ”

They had to arrive at the place designated by Bai Shaoliu, and if they flew away, it would be very fast, but the two of them walked through the primeval jungle unhurriedly, resonating with the strange heaven and earth spiritual breath all the way, capturing and sensing the mystery of refining the heart essence.

Although Yellowstone Park attracts countless tourists every year, the designated areas of stay are developed tourist routes, and the park management also warns visitors not to wander into the wilderness. The park has security guards and local police patrolling back and forth on the highway to confirm and protect the safety of visitors. And deep in the reserve, there is usually only wild animals.

But there will always be people in the world who don't listen to advice, and there will also be people who can't hold back the desire to hunt for adventure, carry bags and mountaineering equipment, park their cars in hidden places to avoid police patrols, and quietly leave the road and enter the depths of the park. Every year, some of them disappear in the mountains and never reappear, becoming a file in countless cases of missing people, and some people disappear without even leaving a police record.

A few years ago, Cheng Tianle also saw the remains of several victims in the depths of Mount Tai in China, far from the tourist route, who may have been distressed in the mountains or died for other reasons. Now, walking through the depths of Yellowstone Park in the United States, he has also found several human remains, which have been killed for varying periods of time, the most recent of which is no more than a year.

Some people fell from high cliffs, some people may have lost their way in the mountains, and some people have been attacked by wild animals. And the most recent victim was even shot and died, which is clearly a homicide. It takes place in the depths of this isolated primeval jungle that no one knows about. These are all stumble-upon encounters along the way, and the locations are not too far from the road.

Walking in the mountains, Xiao Shao suddenly said: "This place is not suitable for human habitation, but it is a paradise for monsters." ”

This area is indeed very suitable for monsters to cultivate and build caves, and before they transform into the red dust, they can also stay away from the interference of human population. Cheng Tianle also encountered some demon birds and demon beasts that had opened their minds, they found Cheng Tianle and Xiao Shao, some had tried to attack, but Cheng Tianle drove them back with natural coercion, and some monsters avoided them from afar.

Although there are not many monsters they have encountered, there are no more than ten in total on the way into the park, but it is not a few, and there should be many monsters who have opened their minds in an area of nearly 10,000 square kilometers. Cheng Tianle also found some traces of suspected caves, although they were very rough, as if they were no different from naturally formed caves, but they had obviously been artificially processed and simply chiseled, and there were traces of spell casting.

Cheng Tianle saw two or three such places on the road, and the skeleton of a demon beast was also found in a long-awaited and half-collapsed "cave". There was once a bison who opened his spiritual wisdom here, and realized that he had become a demon and mastered the natural powers, and it had been groping for self-realization and cultivation for a long time, but finally died here, which should have been long before the establishment of Yellowstone Park.

In this steep mountain wilderness, survival is the biggest test, and there will be all kinds of accidents. Cheng Tianle saw a bison accidentally inhale the poisonous gas that accompanied the eruption of an underground hot spring, and fell to the ground by the spring water. When the herd was gone, the carcass attracted another pack of coyotes, and birds circled in the air.

By the afternoon of the next day, they had finally arrived at the location Bai Shaoliu was referring to. There was a huge volcano nearby, but at the foot was a small hill in an open valley that was not too high, and the exposed rocks were red and cloud-like, probably caused by volcanic eruptions, and looked like burning and dancing flames.

Xiao Shao's spiritual sense was even keen, and she climbed the hill for a long time before she opened her eyes and said, "That's right, it should be here, it is the easiest place to refine the Heart Essence Flame." But I tried it just now, and I'm afraid it's hard to take the Heart Flame Flame, and you and I may not be able to succeed. ”

Cheng Tianle: "Since you have found this place, you have to try your best." In fact, Brother Qiao also said that there is no need to force whether we can harvest the essence of the heart, and we have discovered and sensed its existence, so this trip has not been in vain. Even if you can't harvest that trace of the heart essence flame today, you can still refine the form god and the fire tribulation here. ”

Xiao Shao looked at him and smiled: "But if you don't say it, I know that you still want to do your best to take the Heart Essence Flame, to see if it can melt into the chaotic world in the picture scroll?" ”

Cheng Tianle smiled: "You and I have the same sense of mutual understanding, and only you know my thoughts." At the beginning, the Lord of the Shi Alliance relayed Mr. Feng's words, saying that letting you go to the world of the picture scroll was not to destroy weapons, but to choose a method of refining weapons. This shows that the scroll should be able to continue to be cultivated, but we have not been able to do so. Now that I have finally discovered that the Essence Qi can be transformed into the chaotic world in the picture scroll, and the new changes can be channeled, and the Heart Essence Flame and Shen Yinluo may also be able to, of course I want to see the results. ”

If it weren't for Qiao Caifeng and Bai Shaoliu, even if Cheng Tianle came here, he could sense the strange rhythm in the spiritual breath of heaven and earth, and understood that it was most appropriate to relive the Dan Fire Tribulation here, but he couldn't imagine that there was such a thing as a heart marrow flame in the world. This is the so-called "true transmission of a sentence", but it is necessary to travel thousands of miles and read thousands of books in order to understand and master the subtlety of this sentence.

Xiao Shao looked around and said, "The method of refining the heart essence flame that we have realized along the way must be retreated and sit still, and the primordial spirit will be expanded and integrated into the heavens, earth, mountains and rivers. And this place doesn't seem to be absolutely quiet, I'm afraid someone will disturb it. ”

It is surrounded by a relatively open and gentle valley surrounded by mountains, soft meadows under snow, a clear stream passing by the red hills, and several hot springs of all sizes, which vary in color depending on the depth and temperature. It's only about five kilometres from the nearest road, and there is a winding natural passage through the mountains ahead, so there is not much of an obstacle to walking from the side of the road.

Apparently there were people here, and of course those people were not here to refine the heart flames, but tourists who were hiking and camping.
