What appeared in front of Lin Feng's eyes at this time turned out to be the lava fire he had just obtained! It's just that it was no longer in the form of that small mass of 'fire' at this time, but it was magnified dozens of times, and it could be said that it was in an 'activating' state.

Lin Feng didn't summon this lava fire at all just now, but after using the repair technique, it automatically appeared!

"The repair is complete. ”

"Equipment damage: O. ”

"No need to fix. ”

Just when Lin Feng was shocked by the appearance of the lava fire and was a little stunned, a string of information suddenly appeared in his mind, waking him up.

"Done?!"

Lin Feng was stunned for a moment, and even wondered if he had 'heard' wrong, he looked fixedly, but saw that the strange fire in his hand had dissipated, and there was a new aura jade pendant and some leftover repair materials lying in his hand, he put away the materials, and then checked the aura jade pendant, and now it was indeed intact.

"How long has it been? It doesn't seem like a minute, is it? How can it be repaired so quickly?"

Lin Feng was still a little incredulous, because, in his memory, it should take at least five or six minutes to repair a superb treasure weapon with a damage rate of up to 96%, but just now, it seemed that it only took a few tens of seconds? Even if he was a little miscalculated, it would only take more than a minute at most, right? This Lingguang jade pendant was actually repaired intact!

Moreover, Lin Feng only then reacted again, in the process of repairing just now, the true yuan he consumed was also several percent less than expected!

"It's because ...... Strange Fire?!" After the shock, Lin Feng's mind flashed, and he immediately thought of the key, and said to himself in disbelief, "Strange fire...... It can also be used for repairs, and it can also speed up the repair and reduce the consumption of true elements!"

In order to confirm his guess, Lin Feng took out another spare piece of top-grade treasure-level spiritual light jade talisman, and used the repair technique again, and the lava fire appeared automatically again, and this time it was only after more than thirty seconds, the repair was completed.

"Sure enough!"

The speculation was confirmed, Lin Feng was pleasantly surprised, originally he thought that even if he got the alien fire, it would be useless for the time being, just preparing for the future plan in advance, but he didn't expect that the alien fire could actually have an effect with the repair technique, which was really unexpected.

Speeding up the repair and reducing the consumption of true elements, this effect does not seem to be great, it is nothing more than that it can allow him to earn spirit stones more efficiently, however, if it is in some special circumstances, this improvement can play a great role - for example, when facing the fire-tailed scorpion king before, if there is the help of this strange fire, it is not impossible to repair the spiritual light magic weapon while fighting against many masters of the He family that time, so that it will not be broken.

Subsequently, Lin Feng did another real thing, and now when he uses the repair technique, if he deliberately controls it, he can actually prevent the abnormal fire from appearing, so that the same 'ordinary' flame will appear as before, and the degree and consumption of the repair will no longer change.

I don't know if the skill changes caused by the strange fire are the only ones, but now Lin Feng didn't have the time and mind to study it carefully, and after sorting out his thoughts, he stood up, but instead of leaving here immediately to join Zheng Kai and them, he began to carefully look at this underground cave.

In the records, where the alien fire 'grows', there are often special materials that can make it advanced, and even if there are none, there will be other precious heavenly and earthly treasures, and Lin Feng is naturally unwilling to miss it.

……

"Huh?!Fire Concentrate!So much!!"

Sure enough, just after a few glances, Lin Feng found something good on the cave wall not far from the right, it was a stone with a different color from the surrounding rocks, it was the fire type concentrate!

Lin Feng walked two steps quickly to the side of the mountain wall, directly reached out and grabbed a stone in the low place and broke it hard, and pulled it out of the wall, this is a goose egg-sized fire concentrate, the outside is a little gray and rough, but you can see that its inside is crystal clear and the fire is shining, as if there is a flame beating inside, and the temperature of the hand is also extremely high, as if it has just been taken out of the fire.

"Level 5!!Haha! It's a Level 5 Concentrate!!"

After carefully looking at this concentrate a few times, Lin Feng was even more surprised, because this turned out to be a fifth-level material!

In the grading of refining materials, the fifth level can be said to be a watershed, in a small place like Qingyun City, the fourth level materials are rare, most of the fourth-level materials in the Wanbao Building are transported from other places, the materials from level one to the fourth level are common in those big places, but the fifth level or above, it is very precious.

In the Wanbao Building of Qingyun City, there are no fifth-level materials, even in the Wanbao Building of Biquan City, there are not many.

And now, on the wall of this cave in front of Lin Feng, there are more than ten or twenty pieces of fire concentrate, and it seems that most of them are level five like the ones in their hands!

In the excitement, Lin Feng's movements did not stop, and began to dig these concentrates piece by piece, digging seven or eight pieces in a row, and most of them were level five, and the others were all level four.

After digging the low place, Lin Feng looked up at the remaining concentrate in the high place, he thought about it, and with a wave of his right hand, he took out the flying sword.

"Zheng ......"

The flying sword let out a crisp sword groan, and the entire sword body was still red, as if it had just been taken out of the furnace, and a scorching aura emanated from it, making people dare not touch it.

As soon as Lin Feng waved his hand, the flying sword flew out in the air, and the 'Boom' was drawn on the cave wall like cutting tofu, and every time the sword went down, it would pick out a concentrate and be caught by Lin Feng.

"Five-level, five-level, four-level ...... Huh?!This is ...... Sixth!!"

Every time Lin Feng caught a piece, he glanced at it and put it away, and soon, all the fire concentrate on the wall of a cave in front of him was dug out.

There are nineteen pieces of fire concentrate of different sizes, the smallest one is the size of a goose egg, the largest is the size of a football ball, seven of them are level 4, eleven are level 5, and one is level 6!!

Not to mention anything else, the value of that piece of sixth-grade fire-type concentrate alone that was the size of two goose eggs was far greater than the other eighteen fourth- and fifth-grade concentrates plus the sum of all the heavenly and earthly treasures that had been collected in the cave above!

With excitement, Lin Feng continued to look along the cave wall with great anticipation......

"Fifth Rank Red Shine Stone!!"

"Level 5 Fire Cloud Crystal!"

"It's ...... Serpentine Red Flame Stone!Level 6!!"

“……”

In the spacious and quiet cave, Lin Feng's irrepressible exclamations kept sounding, and he was already so happy that he happily searched for all kinds of high-grade materials in this cave.

After half an hour, Lin Feng turned the entire cave around, and finally stopped after making all the walls around the cave holes.

"Great Harvest...... This is the real harvest!!"

Sweeping through the large pile of various materials piled up in the Acceptance Ring, Lin Feng was overjoyed, compared to this cave, the cave that also had a lot of genius treasures before was simply not worth mentioning - this is the real treasure cave!

It's just that the treasures here are all fire-based spar refining materials, and there is no elixir to grow, so it should be because the environment here is too harsh and there is the influence of different fires, so it can't grow elixir.

In addition, to Lin Feng's slight disappointment, he didn't find a material that could increase the level of the strange fire.

"Shouldn't there be, right? It's time to go to Zheng Kai and them...... That's ......."

Lin Feng was about to leave, but when he subconsciously 'checked' the surroundings again, he inadvertently looked up, but there was a trace of strangeness on the top of the high cave.

Just above his head, he seemed to see an unusual red light flickering.

Lin Feng squinted his eyes and searched carefully for a while, then his eyes lit up, and with a finger of his right hand, the flying sword suspended beside him shot straight up, slashing somewhere on the top of the cave.

A few pieces of rubble spilled down, and in the middle of it, a crimson crystal the size of a goose egg was interspersed!

"Demon Pill!!"

Seeing the falling red crystal, Lin Feng was slightly stunned, and immediately recognized that this was a demon pill, and it was obvious that it should be the demon pill of the Fire Tail Scorpion King, before it exploded and died in the center of the magma pool, Lin Feng thought that its demon pill had sunk into the magma, but he didn't expect it to be embedded in the roof of the cave.

This is a third-level demon pill!

Lin Feng excitedly raised his hand to catch this demon pill, and immediately sensed the powerful energy contained in it, and couldn't help but exclaim slightly: "Huh, this seems to be ...... It's not just a demon pill at the early stage of the third level, right?"

Then he widened his eyes and said in surprise: "Could it be ...... Although the Fire Tail Scorpion King couldn't withstand the powerful energy of the alien fire and died in the end, the realm did soar at that time, and it actually 'gave birth' to a third-level late-stage demon pill!"

The value of the third-level late-stage demon pill is many times higher than that of the early stage, Lin Feng just thought that he could use this demon pill to repair the White Tiger Soul Talisman, but now he dispelled this idea, repairing the White Tiger Soul Talisman, only the third-level early stage demon pill is enough, but it is a bit of a waste to use this late-stage one, this demon pill is kept, and it may be of great use in the future.

Unexpectedly, there would be such an unexpected gain before leaving, Lin Feng was very satisfied, and subconsciously raised his head and glanced at the top of the cave.

"Huh?!and?!"

This time, there was a new appearance, he squinted his eyes and stared carefully at the very center of the cave roof, feeling that there seemed to be a strange light there just now.

"Is it ......?"

Lin Feng looked down, and now directly below that place happened to be the center of the magma pool below, that is, the place where the lava fire was stored before, a flash of inspiration flashed in his mind, he thought of a possibility, and suddenly became excited, and with a wave of his right hand, the flying sword beside him shot out again, shooting towards the top of the cave.

"Boom......"

The flying sword slashed there, and the rubble fell, and in it, Lin Feng saw a little light again, and he immediately thought about it, and the flying sword pierced into the countless gravel and slapped on the red dot.

A small red line flew out, and Lin Feng raised his hand to grasp it in his hand.
