The Yanjing veins in the cave have formed dozens of Yanjing caves under the excavation of the predecessors, but the eight monks are divided into four groups. For safety reasons, only four similar mines can be selected for excavation.

Fang Xingchen originally followed Qi Feng in a group, but when the two walked into the door of a mine, Qi Feng let Fang Xingchen enter the mine alone to excavate, while Qi Feng himself chose another relatively remote mine and walked in.

Qi Feng's move was naturally not aimed at Fang Xingchen, but had his own plans. And Fang Xingchen was very happy with Qi Feng's arrangement, because without Qi Feng by his side, he could rest assured that he could boldly mine Yan Essence ore.

After walking into this mine, which was originally a two-person cooperative mining, Fang Xingchen found that it was pitch black inside, and there were neither fire crystal ore fragments nor flame essence particles on the surrounding rock walls. Only a faint red glow emanating from the depths of the cavern. Fang Xingchen walked for about half an hour before approaching the source of the faint red light.

If you look closely, you will find that this is the end of the mine, and the surrounding rock walls are densely distributed with fiery red flame essence particles, which is a good distribution point of ore veins.

At the same time that Fang Xingchen was mining a large amount of Yan Concentrate ore, a large number of flame bubbles appeared in the magma ocean two hundred kilometers away from here, and then the entire magma ocean changed from a calm body to a violent magma tsunami, and began to spread to the entire Burning Wasteland, swallowing a large area of the wasteland in an instant.

Along with the calm of the first magma tsunami, the second magma tsunami spread more violently towards the east of the Burning Wasteland, and there were even some living beings, revealing strange heads and bodies in the magma tsunami, and emitting extremely piercing roars, as if venting their anger for a long time.

When the third magma tsunami that covered the sky and the sun erupted, a huge flame beast rushed out of the originally calm magma sea with the magma tsunami, and came towards the east of the Burning Wasteland, followed by a group of creatures with flame bodies, some like people, some like beasts, and even more like a combination of humans and beasts. They are like fierce gods returning from hell, and they are full of violence.

However, all this will naturally not be known to the human beings who are far away from the magma ocean. On the contrary, the flower butterfly who was the boss in the Qingcang City Restaurant in the depths seemed to sense something, and then disappeared into Qingcang City out of thin air.

And Fang Xingchen was immersed in the fun of mining Yan Essence ore at the moment, and he didn't know what had just happened in the Burning Wasteland. However, the mine shook three times before, almost making Fang Xingchen think that this place was going to collapse, but the shaking only lasted for a moment before it ended. Fang Xingchen didn't pay attention to it, but wantonly mined the Flame Crystal Ore and put it into the Void Bead.

Today's Fang Xingchen is not a little white monk who didn't know any divine skills a year ago, but a grandmaster-level figure with a large number of divine skills. From the low level to the ultimate, Fang Xingchen cultivated the treasure trove of divine skills he obtained from beginning to end.

Moreover, in this year, Fang Xingchen returned to the uninhabited island where he came to this world, and obtained all the source stones left in the dilapidated buildings, among which there were many extremely precious Five Elements Source Stones, but the most common was a single energy source stone.

Through these energy sources, Shi Fang Xingchen's body has evolved rapidly, but after evolving to an immeasurable realm, it stagnates, and the excess energy absorbed fills the origin space in the chest to the fullest, once creating a phenomenon of body energy overflow.

However, when the five elemental energies converged in the origin space, they formed a vortex-like stable energy structure and guided the more than five elements of energy in the body to circulate indefinitely. When the energy of the five elements was circulating infinitely in the body, Fang Xingchen clearly felt that the absorption rate of the free energy in the space was increasing by the body, and the absorbed energy was channeled into the origin space into some kind of incomprehensible energy compression. Even the well-informed Star Trail had never seen such a terrifying way of absorbing energy, especially the origin space in Fang Xingchen's chest. The ability to compress energy is completely inconsistent with the characteristics of living beings.

Without anyone else present, Fang Xingchen directly used the earth-based advanced divine technique to easily peel the fire essence particles out of the incomparably hard stone, and quickly put them into the storage bag prepared in the void bead.

After an hour passed, the mine where Fang Xingchen was already in had advanced dozens of zhang away, and the pure flame essence mined had already filled a storage bag, with which Fang Xingchen could return to the Lingxiao Sect to create thousands of top-level weapons. However, before he could do this, he still needed to obtain the Qi family's method of smelting and extracting the Yan Essence.

Although Fang Xingchen knew some of the principles of golden smelting on the earth, Yan Jing was not an ordinary metal, so naturally he couldn't use a mortal's set to smelt an extraordinary metal. Maybe, only the Qi family knows the secret of Yan Essence smelting.

"Huh~ Is this it?" When Fang Xingchen peeled off the rock wall through the earth system divine technique, the sudden appearance of fiery red light almost burned Fang Xingchen's eyes, and it turned out to be a fist-sized, fiery red crystal block embedded in the rock wall.

Simply Fang Xingchen directly used his palm to touch the fiery red crystal, and suddenly an extremely strong fire element pure energy began to instill into Fang Xingchen's body, if Fang Xingchen hadn't let go of his hand immediately, he might have been blown up by this strong fire element pure energy.

"Unexpectedly, the fire crystal source stone that has not yet been mined turned out to be the color of fire red all over the body. Through the perception of energy, Fang Xingchen recognized the fiery red crystal as the fiery crystal source stone.

When Fang Xingchen touched the Fire Crystal Source Stone just now, he happened to run the Source Absorbing Dafa, so the scene of frantically absorbing energy just now happened. In order to successfully mine this piece of Fire Crystal Source Stone, Fang Xingchen temporarily terminated the operation of the Source Absorbing Dafa and tried to strip off this red and bewitching Fire Crystal Source Stone.

"What's going on?why can't it be peeled out~" According to Fang Xingchen's prediction, this fist-sized Fire Crystal Source Stone was only deeply embedded in the rock wall, and it could be easily peeled off as long as it was through a high-level earth system divine skill. Who would have thought that Fang Xingchen had consumed a large amount of earth elemental energy to urge the divine skill, and he had not been able to shake this fire crystal source stone.

"Could it be that he couldn't shake this fire crystal source stone, Fang Xingchen had a bold idea in his heart, but he still needed to confirm it.

I saw that Fang Xingchen began to skillfully operate the earth system divine technique, and slowly excavated the rock walls around the fire crystal source stone by peeling off layer by layer. As time passed, the direction finally saw a picture that he couldn't even imagine.

"It turned out to be a vein of fire crystal source stones connected as a whole, no wonder it couldn't be shaken in the slightest~" Looking at the huge fiery red irregular crystals that were revealed after the rock wall was peeled off, even Fang Xingchen, who had seen various energy source stones, was stunned.

In order to explore how big this fire crystal source stone was, Fang Xingchen awakened the dormant star track and asked it to scan and analyze the entire mine. When Star Rail scanned the entire giant fire crystal source stone in front of him, Fang Xingchen realized that he had found a pure fire crystal source stone vein, which extended all the way to the depths of the earth.

With such a huge vein of fire crystal source stone, Fang Xingchen naturally couldn't mine it at one time, so he simply took out the Qingyun Sword and began to split the giant fire crystal source stone in front of him. In order to prevent others from discovering the secret of the fire crystal source stone vein here, Fang Xingchen used the earth system advanced magic technique to backfill the mine after collecting enough fire crystal source stones, and caused the collapse of the mine here.

However, Fang Xingchen specially left an internal space and threw a string of positioning communication beads inside. After finishing the matter of the Yan Concentrate, it is better to go back and continue to mine these cherished fire crystal source stones.
