According to the record of the "Great Wilderness Sutra": flying birds and beetles, living in groups, eight feet long, wingspan of three feet, head like a cat, shape like a vulture, beak like a hook, claws like pincers, good eater of animal corpses, bloodthirsty.

It is very similar to the owl of the mortal world, but it is a hundred times larger than it, and it is nocturnal, ferocious and bloodthirsty.

They had apparently come smelling the blood of the corpses, and the beetles that stretched for miles flew through the air, flying towards the cave like black clouds, and there were at least three thousand of them, almost all of them third-order beetles.

When I chose to settle in the cave on the mountainside, it was to consider the convenience of resisting the demon beasts attacking from below, and the heavy crossbow arrows arranged were all facing downward, so it could not play the slightest defensive role against the demon beasts that flew down from the sky and dived, and the hard work of the daytime was completely in vain.

However, Yun Feng is not a person who gives up easily, not to mention that he wants to protect his benefactor Ye Luoxue, how can he be willing to die in the belly of the demon beast.

He carefully searched for items that could resist demon beasts in the ring of the master, and after several repeated searches, he finally found a light-colored medicine bottle in the pile of items purchased before, opened the medicine bottle, and looked at the pill with a blue glow inside, as if he had caught a glimmer of light in the dark night.

This medicine drifted away with the wind, the monster beast killed immediately where it passed, it is rumored that there was a city besieged by the monster, seeing that the city was about to be broken and people died, there was a mysterious Taoist passing by, only a little wind to the thousand moons, the besieged monsters were all killed immediately, so the legend of the thousand moons and slaughtering the city was left.

The most important feature of this medicine is that it can only be used at night and is only useful for monsters. Yun Feng didn't know if this medicine was also effective against the demon beasts in the secret realm, but he could only take a risk and give it a try.

Fortunately, at this time, the demon beast was still far away from the cave, and he still had time to prepare, Yun Feng was thoughtful, thinking that if he used Fengyu Qianyue directly outside the cave, he would inevitably be affected by the wind direction, resulting in the spread of poison being too random, and there was no guarantee that the demon beasts would be wiped out, even if there was only one demon beast that slipped through the net, he and Miss Ye could not escape, so he had to find a way to use the poison to kill it in a confined space to have a glimmer of life.

Fortunately, he had dug several camouflage caves around, which came in handy at this moment, and he was busy digging out all the corpses of the demon beasts that had been buried before, leaving only dozens of fat and intact beast corpses, and the rest were all burned with fire charms.

He divided the corpse of the monster beast into two parts and dragged them to the cave farthest away from the hiding place, and then widened the cave and dug out the mint grass and stuffed it into the body of the monster, and then buried the corpse of the monster beast into the pit in the cave.

He bought a total of three Fengyu Qianyue pills, and in order to ensure that the toxicity of the medicine could be maximized, he placed one in each of the two holes, and kept the remaining one by his side as a backup.

After the arrangement was completed, the beetle swarm began to approach the cave. He hid in the cave and held his breath, and was letting go of his divine sense to explore the situation outside the cave, when suddenly Ye Luoxue's voice came from his ears: "Senior Brother Yun always has a lot of strange things and ideas, so many third-level demon beasts have long since disappeared if they were others, but you are still thinking about hunting them, it really impresses me." Yun Feng sighed and responded: "I don't know if this poison is effective against the demon beasts in the secret realm, but since I said that I would protect you, I will never leave this cave, let alone sit still, as long as there is a chance, I will never give up, why is this not the case for Senior Sister Ye?" Ye Luoxue felt the seriousness and perseverance in Yun Feng's words, smiled slightly, and said with starlight in her bright eyes: "Senior Brother Yun is really different. The two looked at each other from a distance and then tacitly stopped talking.

As the group of demon beasts approached, the atmosphere in the cave became more tense, although Ye Luoxue was unable to move, she also made a gesture of defending against the enemy, she was a strong person and did not want to blindly rely on the protection of Yunfeng.

As they arrived at the cave where they were, they became even more restless, and when they had come in groups because they had smelled blood and the rancid stench of corpses, they had smelled their favorite mint grass when they got closer, and the combined temptation aroused their thirst for blood, and they were eager to eat the delicious food at once.

After the leader identified the hole where the corpse of the demon beast was hidden, he issued an order to swoop into the cave like crazy, and the other beetles also lost their minds and swooped towards the two caves, in order to grab the food, the monsters even bit and chased each other, and in a moment, the two caves had been filled with beetles, and they were densely packed together to compete for the share of the beast corpses and mint grass.

Seeing this opportunity, Yun Feng no longer hesitated, and immediately used his divine sense to open the two Fengyu Qianyue pills, and the medicinal powder hidden in the pills immediately spread with the wind, and in an instant, the beetles fell to the ground one after another, and the demon beasts that followed into the cave inhaled Qianyu Fengyue Qi and died before they understood the reason, and the group of demon beasts flew in batches like waves and fell to the ground in batches, and countless people died in the blink of an eye.

The follow-up demon beasts have long been lost by the heavy smell of blood and mint grass, and still rush into the cave regardless of life and death, about a pillar of incense time, until the last beetle also flew into the cave and died of poison, there is no more demon beast outside, so far the entire beetle group has been completely wiped out, and no one is left.

Ye Luoxue was stunned when she saw the miracle effect of Feng Yu Qianyue for the first time, and looked at Yun Feng with her mouth slightly open and her eyes widened, with a look of surprise, as if she had not yet recovered from the scene detected by her divine sense, Yun Feng looked at Ye Luoxue's stunned appearance, snickered in her heart, and said: "I didn't expect this Feng Yu Qianyue to be as powerful as rumored, I must buy a bottle and give it to Senior Sister Ye after I get out of the secret realm" Ye Luoxue realized his gaffe, and replied with a slightly red face: "Senior Brother Yun has a good method, just this one move has destroyed so many third-order demon beasts, Luoxue admires."

Yun Feng heard Ye Luoxue's praise, although he couldn't help but be proud in his heart, he still replied modestly: "It's just a means of borrowing poison, if I really rely on my own ability, I will not be defeated a thousand times."

Yun Feng observed in the cave for nearly half an hour, and only after confirming that there were no more demon beasts that had slipped through the net, he cautiously walked out of the cave, the night was as dark as ink, quiet as water, and the slightest sound could not be heard outside the cave.

He cautiously walked into one of the caves arranged, and Rao was still shocked by the real scene in front of him: countless corpses of beetles were piled up all over the cave, and the demon beasts still retained the crazy expressions of greed and bloodthirstiness before their deaths, apparently dying the moment they inhaled the poisonous gas.

In order to avoid long nights and dreams, Yun Feng took advantage of the night to start disposing of the corpses of the demon beasts, and only after several hours of busy work did he take out all the inner pills one by one, and he buried the mountain of demon beasts in the giant pit and then concentrated on burning them after dawn.

These demon beast inner pills are roughly estimated to have about three thousand five hundred inner pills, almost all of them are third-order inner pills, which is more than the entire secret realm of many small sects.

Ye Luoxue couldn't detect too far because of his serious injuries, so he could only watch Yun Feng busy around at the mouth of the cave, and after a night of worry, his mentality gradually calmed down at this moment: in the future, all safety will be handed over to Yun Feng, life is the same life, death is death together, even if he can't escape this catastrophe, with his company, he will die without regrets
