"Could it be...... It's an advanced spiritual material of a different fire?!"

Thinking of this possibility, Lin Feng suddenly felt a little surprised in his heart, and he immediately beckoned everyone: "Everyone, go over here and take a look!!"

Lin Feng walked in front first, Longbow Xiaojing and others followed behind him, Yan Can protected the rear, and everyone walked into the relatively narrow passage, under the reflection of the lighting spar, the surrounding cave walls were covered with unknown black moss, and there was constantly turbid liquid seeping out from the opportunity to flow down the cave wall, and there was only the slight footsteps of everyone walking in the entire cave, which seemed a little gloomy. (Please search for the fastest novel website!)

The cave was not straight, but quite winding, and almost made everyone dizzy, and they didn't know how far they had gone, but they felt that the temperature around them seemed to be getting higher and higher, and the walls of the cave around them became dry and cracked, and finally, everyone came to a huge and spacious space.

It is unimaginable that there is such a large space in a mountain, the size of a football field, and at the end of this space, there is a wide and turbulent underground dark river!

The two ends of the river lead into the cave walls, and I don't know where it comes from or where it flows, and the most strange thing is that it is obviously a swamp outside, which is really difficult to understand how this river was formed, and the river is obviously not swamp mud, but rather cool water.

"Hill Hill!!" the hill stood on Lin Feng's shoulder, his little paw waving towards the top of the cave, looking quite excited.

In fact, there was no need for it to remind him, after Lin Feng came here, he immediately looked up at it as if he had noticed it - on the top of the cave, there was a place that seemed to be burned, like a large ceiling lamp with eye-catching firelight, making this spacious space seem quite bright.

Not only Lin Feng, but the others also noticed this peculiarity for the first time, and they all looked up, Long Fei exclaimed: "No wonder the temperature here is so high, it turns out to be a fire attribute spiritual material!

"Yang Yan Jing Jingjing!!" Before Yan Can could answer, Lin Feng couldn't help but be pleasantly surprised, "That's Yang Yan Jing Jingjing!!"

"Yang Yan Jingjing?" Everyone was stunned, they didn't do detailed research on this aspect like Lin Feng, even Yan Can didn't know about this kind of spiritual treasure, because it was a very rare and special spiritual material.

As an alchemy sect, Ling Yuemen naturally has a lot of classics about different fires, and Lin Feng has basically carefully studied everything he can find in the past six months, and has a good understanding of many different fires. Different fire is also divided into grades like magic weapons, and the grade improvement of different fire depends on a variety of different strange spiritual materials, this Yang Yan Essence Crystal is one of the spiritual materials required for many different fire upgrades, and the lava fire that Lin Feng has has is among the materials required for upgrading!

The strange fire attribute spar that he got together when he got the lava fire at the bottom of the Chiyan Mountain, Lin Feng later learned that it was a precious spiritual material called 'Red Molten Essence Crystal', which was one of the two spiritual materials needed to upgrade the lava fire, that is to say, as long as he got the Yang Yan Essence Crystal in front of him, Lin Feng's lava fire could be upgraded by one grade!

The benefits of lava fire, Lin Feng naturally knows very well, if he can upgrade by one grade, from the lower grade to the middle grade, then whether it is used for repair, alchemy, or battle, it will be even more powerful!

Lin Feng also wanted to ask Wanbaolou to help find this spiritual material, but Duan Chenglian clearly told him that he couldn't do it at that time, because even if Wanbaolou received this spiritual material, it would be immediately given by those powerful refiners with alien fire above, and it would be impossible for it to flow to the lower level.

So now that he saw this Yang Yan Essence Crystal, Lin Feng seemed a little excited, and he said to Yan Can: "Brother Yan, I have a lot of use for this Yang Yan Essence Crystal, please give it to me, I can let out the genius earth treasure I found later." ”

Yan Can also came back to his senses from surprise, and he smiled: "Since this is a spiritual material that upgrades the alien fire, it can naturally be wielded in your hands, you can take it, I have no opinion." ”

"Thank you!!" Lin Feng hugged his fists, and without further words, he immediately raised his feet and walked forward, and at the same time took out the Red Soul Flying Sword, preparing to dig down the Yang Yan Essence Crystal on the top of the cave.

However, at this moment......

"Mound!!"

"Lin Feng be careful!!"

Xiaoqiu's scream and Yan Can's exclamation sounded almost at the same time, and then before Lin Feng could react, he heard a 'bang' explosion, and in the turbulent river in front of him, there was a sudden explosion of water, and a huge figure burst out and rushed towards him!

A deafening strange roar sounded !! followed, which was a bit like a dragon's groan, and even made the weaker Longbow Xiao Jing and Zhang Fangzhou feel a little trance.

"Huh......" Just when this huge figure was about to pounce in front of Lin Feng in the blink of an eye, a cyan sword light suddenly broke through the air above Lin Feng's head, and crashed into the giant shadow in the blink of an eye!

"Boom!!" A piercing sound of gold and iron clashing, Yan Can's flying sword hit the figure, but it only splashed a string of sparks, and then it was bounced away!

But Yan Can's blow finally bought Lin Feng a little time, allowing him to make a defense, he almost subconsciously excites the spiritual light jade talisman that has been held in his left hand with all his might, the next moment the golden spiritual light mask appeared, a thick whip shadow swept over, and the spiritual light shield that had just been formed shook violently, and then collapsed violently!!

Fortunately, when the aura mask collapsed, Lin Feng had already kicked the ground and retreated sharply, the thick 'whip shadow' almost swept the tip of his nose, and the strong wind even cut a few small blood cuts on his cheeks, but he finally managed to dodge this dangerous blow.

The 'attacker' attack was blocked and stopped where Lin Feng was standing just now, and Lin Feng retreated again and again with some wolves, until he retreated in front of Yan Can and the others, and then stopped.

......

A qiē was born between the lightning and flint, but Lin Feng felt that he had already walked in front of the ghost gate, he looked up in shock, and finally saw the appearance of the attacker clearly, and then his face changed greatly!

It was a monster as huge as a bus, covered with dark red scale armor, as if it had been burned red, and its appearance was like a mutated lizard, but there were two ugly bumps on the top of its head, two or three of which looked like dragon horns.

"Red Jiao Beast!Level 3...... Ninth Order!!"――
