After leaving the World Society, Ye Feng walked towards Lingyun Cave non-stop.

The entrance of Lingyun Cave is located in the Leshan Giant Buddha in Leshan, and Ye Feng took a boat down the river and soon reached his destination.

However, considering that the roads in the Lingyun Cave were intricate and easy to get lost without any guidance, Ye Feng did not enter immediately.

After Ye Feng purchased a lot of food from the surrounding area and was ready for long-term exploration, he entered Lingyun Cave.

The passage of the entire Lingyun Cave has been roasted and calcined by the blazing flames of the fire qilin for many years, and all parts of the passage are very hot and dry.

Ye Feng only entered the Lingyun Cave for a few meters, and he could feel this blazing power. Ye Feng couldn't help but run **, as the blazing power was inhaled into the refining, what made Ye Feng very happy was that just the remaining flame power of the fire qilin on the periphery of this Lingyun Cave made the small flame in Ye Feng's heart feel like he had eaten a big tonic pill.

Ye Feng was very happy in his heart, if he could meet the fire qilin and absorb some of the flames on the fire qilin's body to refine, he believed that the flames in his heart would definitely be greatly transformed.

It's just that after Ye Feng entered the Lingyun Cave, he had been looking for more than half a month in the passage unremittingly, not to mention the fire qilin, except for the spotless fiery red wall, Ye Feng didn't see anything.

Fortunately, for more than half a month, Ye Feng has put most of his mind on figuring out martial arts and cultivation, otherwise Ye Feng doesn't know if he can persevere.

After walking for a few more days, Ye Feng suddenly found that a cave in front of him seemed to be a little different, Ye Feng was overjoyed in his heart, and walked away quickly.

I saw that there was a pile of rubble on one side of the cave, and next to the pile of rubble there was a skeleton of a skeleton chained by cold iron chains. Come to think of it, this skeleton is Nie Ying, the ancestor of Nie Feng.

According to the records in the original book, back then, the fire unicorn was in trouble everywhere, Nie Feng's ancestor Nie Ying was Ze Cangsheng, and resolutely fought to the death with the fire unicorn in Lingyun Cave, after a long battle, although Nie Ying injured the fire unicorn, but unfortunately, Nie Ying also swallowed the unicorn demon blood by mistake at the same time.

After returning home, his body underwent drastic changes, and his strength increased to an incredible level. What's even more terrifying is that there is an inexplicable and intense killing slack that spreads in his blood, causing him to rise up from time to time to kill the ferocious spirit, regenerate his anger, and become perverse and unpredictable.

At that time, Nie Ying found that the killing intent in his body was gradually reaching its peak, and it was difficult to control himself, he was angry and difficult from time to time, and when he had a rational opportunity, he was afraid of hurting his lover, so he took the night without saying goodbye and came to Baijian Villa to ask for help from his best friend Ao Ri, the owner of Baijian Villa, who is also the ancestor of Aotian, and told him about it.

At that time, Ao Ri was a master of swordsmiths, and he had a piece of cold iron that had been in the dark for thousands of years. After learning the details, the two continued to research, and finally realized that they had to forge the cold iron into a sword of the extreme cold in order to destroy the hottest fire unicorn and restrain Nie Ying's mad blood.

Although the proud sun immediately started to forge and refine the peerless sword day and night, the casting of divine weapons is by no means something that can be produced overnight after all.

Due to his increasingly murderous nature, Nie Ying was afraid of leaving a calamity in the martial arts, so he had to lock himself in the crypt of Lingyun Cave with a thick rope and iron chain, hoping that the birth of the peerless sword could save him. It's a pity that until Nie Ying's death, the peerless sword was not cast.

What's even more lamentable, later, Nie Ying originally created the Ice Heart Technique to suppress the crazy blood in his body, but he was locked by an iron lock, and he couldn't leave if he wanted to, and he was starved to death here.

It's a shame that it's a generation. Ye Feng couldn't help but sigh in his heart.

After sighing, Ye Feng reined in his mind and began to look for the Ice Heart Technique left by Nie Ying, this Ice Heart Technique can not only suppress the heart demons, but even more rare is that some Ice Heart Determination is also a one-step method for cultivating the spirit.

Ye Fengzai carefully investigated, and finally found the mantra of the Ice Heart Formula on the stone wall.

As for the Aohan Six Tricks and the Snow Drink Crazy Knife, Ye Feng didn't take it. First, this Aohan Six Tricks is a knife technique, Ye Feng himself uses a sword, and it is not very useful to remember, and secondly, the Aohan Six Tricks and the Snow Drink Crazy Knife can only exert their maximum power when they are used together, for Ye Feng, taking away the treasure knife will only make the treasure knife dusty, it is better to let the treasure knife wait for his real master here.

After Ye Feng memorized the Ice Heart Technique, Ye Feng walked directly to the depths of the cave step by step.

Ye Feng remembered that after Nie Feng found this in the original book, he found the Blood Boti after walking a short distance, which means that the Blood Boti is near here.

Ye Feng continued to move along this passage, and after countless turns, he saw another cave appear in front of him.

Walking into the cave, I saw that the entire cave flashed with a flaming red light. Ye Feng looked at it fixedly, looking for the source, and saw that this flame red light was emitting from the red fruit on the cave wall.

Blood Boti, Ye Feng recognized this thing at a glance, and finally found it after spending so much effort.

It is said that this Blood Bodhi is not only a healing holy product, but also the first time you take it, you can increase your power for at least thirty years.

Ye Feng suppressed his excitement and walked to the side of the wall where the blood bodhi grew, there were at least hundreds of blood bodhi on the wall, these blood bodhi were like a flame red gem, emitting a faint red light, densely growing on the intertwined and intertwined vines.

Ye Feng gently plucked a Blood Bodhi and put it in the palm of his hand, although the Blood Bodhi was born from the blood cast of the Fire Qilin. But on the surface, there is no heat at all, and when you put it in your hand, it only feels cold and abnormal.

Ye Feng put the blood bodhi on the tip of his nose and sniffed it gently, and a fragrance entered Ye Yefeng's body, and suddenly Ye Feng felt that his spirit became vibrant.

Ye Feng no longer hesitated, and casually swallowed the blood Bodhi in his hand.

This blood bodhi melted in his mouth, and Ye Feng suddenly felt a coolness in his mouth. Then a strange internal force began to boil in Ye Feng's body, and at the same time, Ye Feng also felt a heat force running rampant in Ye Feng's body.

Fortunately, Ye Feng was already in the late stage of the mortal immortal, and his mana was extremely profound, so Ye Feng's refining of this skill was very smooth.

After a while, Ye Feng refined this power for his own use, and in an instant, Ye Feng had almost increased his power by about thirty years.

Ye Feng also directly broke through from the late stage of the Mortal Immortal to the Great Perfection of the Mortal Immortal. At the same time, Ye Feng also felt that the strength of his body and flesh had increased significantly.

It was really a good thing, Ye Feng secretly admired it in his heart. It's just a pity that only the first time you take it can you increase your strength, and then no matter how much you take it, it can only be used for healing. Otherwise, I can directly use the Blood Bodhi to suddenly reach the realm of human immortals.

Thinking of this, Ye Feng couldn't help but shake his head, secretly sighing that it was a great joy to be able to increase his strength for thirty years, he was greedy, and he should be content.

Then, Ye Feng removed seven or eight percent of the remaining Blood Boti, and then went to the other passages of Lingyun Cave step by step.
