(I am afraid that some book friends will not pay attention, so I will explain again: Yunhai is in another place at this time and has no time to surf the Internet or code. What you see now is a regular update of the manuscripts. This week, you can only update once a day. After Yunhai returns home, you will compensate for three updates every day next week. Please forgive me.)

What appeared in front of Lin Feng at this time was the lava fire he had just obtained! However, it was no longer the small "fire" form at this time, but it was magnified dozens of times, and it can be said that it was in the "activated" state.

Lin Feng did not summon the lava fire at all just now, but after using the repair technique, it automatically emerged!

“Repair is complete.”

“Equipment damage degree: 0.”

“No repair is required.”

Just as Lin Feng was stunned by the appearance of the lava fire, a string of information suddenly appeared in his mind, awakening him.

“Completed?!”

Lin Feng was stunned and even wondered if he had "heard" wrong. He looked closely and saw that the strange fire in his hand had disappeared. In his hand was the brand new-looking jade pendant and some remaining repair materials. He put away the materials, then checked the jade pendant and found that it was indeed intact.

"How long has it been just now? It seems that it hasn't been a minute, right? How could it be repaired so quickly?"

Lin Feng was a little unbelievable because, in his memory, it would take at least five or six minutes to repair a top-quality treasure with a damage of up to 96%. But just now, it seemed that it only took dozens of seconds. Even if he was in a daze, it would only take more than one minute at most? This spiritual jade pendant was repaired intact!

Moreover, Lin Feng then realized that during the repair process just now, the true energy he consumed was several% less than expected!

"Is it because... strange fire?!" After being shocked, Lin Feng's mind flashed, and he immediately thought of the key. He said to himself in surprise, "The strange fire... can actually be used for repair techniques? Moreover, it can also speed up the repair speed and reduce the consumption of true energy!"

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

"Sure enough!"

The speculation was confirmed, and Lin Feng was very surprised. He originally thought that even if he got the strange fire, it would be of no use for the time being. He was just preparing for the future plan in advance, but he did not expect that the strange fire could still have an effect with the repair technique. This was really a surprise.

Accelerating the repair speed and reducing the consumption of true energy, this effect does not seem to be great. It is nothing more than allowing him to earn spirit stones more efficiently in normal times. However, if it is in some special circumstances, this improvement can be of great help - for example, when facing the Fire-tailed Scorpion King before, if there was the help of this strange fire, it would be not impossible to fight against many masters of the He family while repairing the spiritual magic weapon while not being compromised.

Later, Lin Feng conducted another experiment and found that if he deliberately controlled it when using the repair technique, he could prevent the strange fire from appearing. In that case, the same "ordinary" flame would appear as before, and the speed and consumption of repair would no longer change.

I don’t know if the only skill changes caused by the strange fire are the only ones. However, Lin Feng has no time and mind to study them carefully. After sorting out his thoughts, he stood up, but did not leave here immediately to meet with Zheng Kai and the others, but began to carefully look at the underground cave.

According to records, where the strange fire "grows" often have special materials that can advance it. Even if there is not, there will be other precious treasures of heaven and earth, so Lin Feng naturally does not want to miss it.

...

"Hmm?! Fire concentrate! So much!!"

Sure enough, after just a few glances, Lin Feng found good things on the wall of the cave not far from the right. They were stones with different colors from the surrounding rocks, and they were fire-type concentrates!

Lin Feng took two steps to the mountain wall, and directly reached out to grab a stone at the low place and broke it hard, then pulled it out of the wall. This was a fire-type concentrate the size of a goose egg. It was a bit dark and rough outside, but you could see that it was crystal clear and sparkling inside, as if a ball of flame was jumping inside, and the temperature at the entrance was also extremely high, as if it had just been taken out of the fire.

"Level 5! Haha! It's actually a level 5 concentrate!!"

After carefully looking at this concentrate, Lin Feng was even more surprised because it turned out to be a level 5 material!

In the classification of refining materials, Level 5 can be said to be a watershed. In small places like Qingyun City, Level 4 materials are rare. Most of the Level 4 materials in Wanbao Building are transported from other places. Level 1 to 4 materials are common in large places, but Level 5 or above are very precious.

There are no Level 5 materials in the Wanbao Building in Qingyun City, and there are not many in the Wanbao Building in Biquan City.

Now, there are more than a dozen or twenty fire-type concentrates on the wall in front of Lin Feng, and it seems that most of them are level 5 like the ones in their hands!

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

After digging the low place, Lin Feng looked up at the remaining concentrate at the high place. He thought for a while, waved his right hand and took out the flying sword.

"Zheng..."

The flying sword emitted a crisp sword roar, and the entire sword body was still red, as if it had just been taken out of the stove. A burning aura emanated from it, making people afraid to touch it.

Lin Feng waved his hand and the flying sword flew out in the air. "Swish Swish Swish" slashed on the cave wall like cutting tofu. Whenever the sword went down, a concentrate would be picked out and was caught by Lin Feng.

"Level 5, level 5, level 4...Huh?! This is... level 6!!"

Every time Lin Feng caught a piece, he would take a look and then put it away. Soon, all the fire concentrates on the hole wall in front of him were dug out.

There are nineteen fire concentrates of different sizes, the smallest ones are the size of goose eggs, and the largest ones are the size of football, seven of which are level 4, eleven or five, and one or six!!

Not to mention anything else, the value of the six-level fire concentrate just is far greater than the remaining eighteen level 4 or five-level concentrate plus the sum of all the treasures collected in the cave above!

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

"Level 5 Red Stone!!"

"Level 5 Fire Cloud Crystal!"

"This is...Snake Pattern Red Flame Stone! Level 6!!"

“…”

In the spacious and quiet cave, Lin Feng couldn't help but scream. He was so happy that he couldn't stop and was plundering various high-end materials in the cave happily.

After half an hour, Lin Feng turned the entire cave around and made the surrounding cave walls full of holes, and finally stopped.

"A great harvest...this is the real harvest!!"

After scanning the piles of various materials in the object storage ring, Lin Feng was overjoyed. Compared with this cave, the cave with many talented treasures before was simply not worth mentioning - this is the real treasure cave!

However, all the treasures here are fire crystal refining materials, and there is no spiritual medicine to grow. I think it is because the environment here is too harsh and the influence of strange fire, so spiritual medicine cannot be grown.

In addition, what a little disappointed Lin Feng was that he did not find any materials that could increase the level of strange fire.

"It should be gone, right? It's time to find Zheng Kai and the others... Huh?! That's..."

Lin Feng was about to leave, but when he subconsciously "checked" the surroundings again, he accidentally raised his head and found a trace of strangeness on the top of the high cave.

Just above his head, I seemed to see an unusual red light flashing just now.

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

Several pieces of gravel fell down, and in it, there was a red crystal the size of a goose egg!

"Demon Pill!!"

Seeing the falling red crystal clearly, Lin Feng was slightly stunned and immediately recognized that it was a demon pill, and it was obviously the demon pill of the Fire-tailed Scorpion King. It had exploded in the middle of the magma pool before and died. Lin Feng thought that its demon pill had sank into the magma, but he didn't expect it to fly into the top of the cave.

This is a level three demon pill!

Lin Feng raised his hand excitedly to catch the demon pill, and immediately sensed the powerful energy contained in it. He couldn't help but say a little shocked: "Huh? This seems... not just the demon pill at the early stage of level 3, right?"

Then he widened his eyes and said in surprise: "Is it... it's from the late stage of level 3?! Although the Fire-tailed Scorpion King could not bear the powerful energy explosion of the strange fire in the end and died, his realm did soar at that time, and he actually "produced" a late stage demon pill!"

The value of the third-level 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 has given up this idea and repair the White Tiger Soul Talisman. Only the third-level demon pill is needed. Using this late stage is a bit waste. Keeping this demon pill may be of great use in the future.

Unexpectedly, he could still find such an unexpected gain before leaving. Lin Feng was very satisfied and subconsciously looked up and glanced at the top of the cave.

"Huh?! And?!"

At this glance, he actually made a new discovery. He squinted his eyes and stared at the center of the cave, feeling that he seemed to have found another strange light there just now.

"Can't it..."

Lin Feng looked down and found that the center of the magma pool below was just below, which was where the lava fire existed before. A flash of inspiration flashed in his mind. When he thought of a possibility, he became excited. With a wave of his right hand, the flying sword beside him shot out again and shot towards the top of the cave.

"Swish swish swish swish..."

The flying sword cut out, and the gravel fell. In it, Lin Feng saw a little light again. He immediately thought about it, and the flying sword penetrated into countless gravels and slapped on the red dot.
