Yang Fan thought about it and was a little relieved, since the magical little tree could appear in such a harsh environment, it was understandable that it suddenly disappeared. Pen & Fun & Pavilion www.biquge.info

Heaven and earth spiritual objects are not at all a category that ordinary people can understand, just like Yang Fan inexplicably returned to this world after being reborn, many things are not something that people can control and completely understand.

Human beings have many facts and phenomena that cannot be explained by this world. After all, man is not a god, and this may be the limitation of human beings, right?

Yang Fan cleaned up his mood and walked to the edge of the boulder, only to know why he felt that the change in the origin energy of the Heaven and Earth Fire Attribute in the Tiankeng was very drastic just now.

Inside the sinkhole was originally a small magma lake with a radius of several hundred steps, but now the magma lake has dried up and disappeared, just like that magical little tree and disappeared out of thin air.

The entire sinkhole was covered with solidified rock, and there was no longer magma with fire attribute energy.

It seems that during this period of Yang Fan's cultivation, the magma in the entire sinkhole suddenly cooled down and solidified, turning into a deep pit of limestone.

The boulder that Yang Fan is standing on now seems to have turned into an independent high platform more than ten meters high. Yang Fan remembers that the boulder protruded several meters above the surface of the magma lake at the time, and now it seems that the entire magma at the bottom of the sinkhole has dropped by almost ten meters, exposing part of the original magma-covered pit bottom.

Yang Fan looked at it, and the rope he tied to the edge of the sinkhole at one end was still on the boulder, and he was relieved. More than 100 meters of sinkholes, those pit walls are very steep, but the top is small and the bottom is large, there is no place to stay. If it weren't for the rope that climbed upward, even if he had the strength to open the tenfold peak of the Enlightenment Realm, it would be a little difficult to climb to the top of the sinkhole.

Yang Fan just wanted to tie the rope around his waist and make a seatbelt-like live buckle, but the little purple squirrel scratched Yang Fan's chin with its small claws on Yang Fan's chest, which startled Yang Fan. This little guy, his claws must be very sharp, so he is not afraid of scratching Lao Tzu's face with a claw?

The little purple squirrel jumped down from Yang Fan's body, twisted its small body, and slipped down under the boulder like a smoke. Its body was so small that it slid down the edge of the high platform formed by the boulder.

Yang Fan hurriedly followed behind the purple squirrel, also looking for a place to stay, and landed under the high platform. The slope of this high platform is a little steep, but it is not difficult for Yang Fan and Little Purple Squirrel.

As the little guy descended a few meters, the little purple squirrel suddenly stopped and began to dig with its sharp claws on a stone wall.

Yang Fan was a little confused, this place was just an ordinary stone wall, there was nothing special, I didn't know what the little purple squirrel was looking for.

In a few breaths, Yang Fan knew the answer, and the little purple squirrel dug dozens of times from this stone wall, and took out a crystal as red as a walnut from it.

The little purple squirrel held the crystal, which was not small for it, with two small paws, and threw it at Yang Fan.

Stretching out his hand to take the red crystal, Yang Fan sensed the violent fire attribute energy in it, and immediately remembered the energy crystal mentioned in the book introducing the treasure of heaven and earth, also called Yuan Jing.

This crystal containing rich fire attribute energy is called Fire Yuan Crystal, and other attribute energy crystals such as Water Yuan Crystal and Lei Yuan Crystal are also available. They are a kind of energy crystallization produced in the land where the origin energy of heaven and earth is rich, and it contains very pure attribute energy, which is an important resource for refining yuan soldiers, machinery, and refining puppets, which is even rarer than the inner pill of this demon beast, and the demand is more.

There are two main materials for Yuan Bing. One is the hard parts of the body such as the claws, bone spurs, and tail of the demon beast, which is the source soldier with the body part of the demon beast as the main material, and needs to be embedded with the core of the demon beast of the same attribute or even the inner dan, or the core of the demon beast and the inner dan of this main material are the best.

In this way, the attribute energy in the Yuan Soldier is easy to fuse, and after using the powerhouse above the innate realm of this source and Yuan Soldier to infuse the same attribute energy into the Yuan Bing, this Yuan Soldier can greatly improve the user's strength. When the attribute energy in the body of the Innate Pulse Practitioner is added to the attribute energy in the Yuan Soldier, the combat skills that can be displayed will be doubled in power.

Another kind of Yuan Bing is mainly refined by metals with special hardness, toughness, elasticity and sharpness, and what needs to be inlaid in these Yuan Bing is not the core of the demon beast and the inner Dan, but the Yuan Crystal of these various attributes. There are also some mechanisms, machines, or puppets that also use Yuan Jing as the power core.

Huo Yuanjing is one of the Yuan Crystals that can be found in the outside world, but the number is not much, otherwise there would not be so few Yuan Soldiers in this world. Even though some people have a variety of ores suitable for refining Yuan Bing, most of them do not have suitable Yuan Crystals to provide energy.

The most frustrating thing is that whether it is the demon beast core, the inner pill or the attribute yuan crystal, they are all consumable. Maybe your main material can be used for thousands of years and will not be destroyed, but the demon beast core, inner pill and yuan crystal have been used many times, and after consuming the energy inside, you need to replace the core, inner pill or yuan crystal, so even if someone has the demon beast core inner pill or yuan crystal in their hands, they will not easily trade it, because this kind of thing is a necessity for the strong above the innate realm, and it is a very versatile consumable, and everyone is in short supply.

The purple squirrel began to carry out its treasure hunt around the high platform formed by the boulder. One by one, the fire yuan crystals were dug out of the stone wall by the little guy.

After looking around on this high platform, the little purple squirrel dug up sixteen large and small fire yuan crystals, as well as three thunder yuan crystals like purple grapes.

This kind of Lei Yuan Crystal is rarer and more precious than the Fire Source Crystal.

When he went down to the bottom of this sinkhole, Yang Fan thought that the little purple squirrel's treasure hunt was about to end, but he didn't expect it to dig up again at the bottom of the sinkhole and the surrounding stone walls. It seems that this little purple squirrel is a little guy who can sense ore-type treasures, which is comparable to the little golden snake's ability to find medicinal herb-type treasures.

On the way here, the little golden snake found more than a dozen of the most important blending medicinal fruits for Yang Fan to refine the Shengyuan Pill, as well as a few medicinal herbs that could heal external injuries.

The little purple squirrel jumped up and down and was busy, Yang Fan played next to him, and it didn't take long for the little guy to turn the sinkhole upside down, and the stone walls around the sinkhole were also chiseled, and a total of thirty-eight red fire yuan crystals and nine purple thunder yuan crystals were obtained, which made Yang Fan's heart bloom.

This time I really picked up a treasure, or a living treasure, think about the future when looking for natural treasures, the little golden snake is responsible for finding herbs, the little purple squirrel is responsible for finding ores, and Young Master Yang is responsible for putting it in the bag, what a comfortable and chic treasure hunting career, and it began!

When Yang Fan finished counting the harvest and put all the Yuan Crystals into a sturdy small leather bag, and wanted to put them away, he suddenly felt an itch in his jaw, and it was the little purple squirrel scratching with its little paws.

The little guy grabbed Yang Fan's collar with his other paw, looked at Yang Fan with his eyes, and a small silky hala already flowed from the corner of his mouth.

Seeing the pleading eyes of the little purple squirrel, Yang Fan was also drunk!
