Wu Yan stood at the door of the insect breeding room, with a hint of crying and laughing on his face.

More than 10,000 "horned vipers" in the "horned viper" insect breeding room were successfully devoured and advanced as early as 15 years ago, and more than 2,100 "dragon vipers" were born. This "dragon-headed ink viper" was born peculiar, its whole body was covered with black gold-like scales, no longer than a ruler, with horns on its head, and its appearance was like a mini black jiao. The action was as fast as lightning, and each formed "dragon viper" had the strength of the peak of the qi refining period. With more than 2,100 "dragon vipers", it is conceivable that the amount of poison consumed every day can be imagined. If it weren't for Wu Yan having that small furnace in his hand, constantly cultivating spirit grass poison and refining poison spirit feeding, I'm afraid these "dragon vipers" would have starved to death a long time ago, where would they still grow until now. After ten years of continuous cultivation, 2,000 of the more than 2,100 "dragon vipers" have entered dormancy again because they have absorbed and devoured enough re-cultivated ink viper vines, preparing for another evolution.

In addition, the "dragon viper" that failed to continue to evolve, but when Wu Yan was meditating and refining qi, he somehow broke through the magic circle of the insect breeding room, got into another insect breeding room, and devoured the golden scale seven-inch snake newly cultivated by Wu Yan in the insect breeding room. By the time Wu Yan found out, it was already too late. These more than 100 "dragon vipers", after devouring the more than 300 golden-scaled seven-inch snakes, actually entered dormancy in the magic circle that cultivated the golden-scaled seven-inch snakes.

Encountering this situation, Wu Yan was extremely distressed and at the same time, he had no tricks. All the snake eggs of the golden-scaled seven-inch snake hatched, and he had nowhere to look for the snake eggs of this kind of spirit snake. In desperation, Wu Yan could only continue to cultivate the other four poisonous insects, and at the same time checked the magic circle of the "Horned Viper" insect breeding room and re-strengthened it.

For a period of time after the incident of the "horned viper" devouring the golden-scaled seven-inch snake, Wu Yan was really busy. He once again expanded the cave stone chamber where the poison was cultivated, and cultivated more poisons to maintain the supply of poison sources in the "dragon viper" insect breeding chamber to avoid evolutionary failure. The other four poisonous insects, because they have matured, the demand for poison sources has also increased greatly.

After another five years, Wu Yan's cultivation also entered a critical period. He realized that his cultivation had reached the late stage of foundation building, and he was about to reach the realm of Great Perfection. Although he didn't have any experience in knotting pills, Wu Yan still took out the ten Swallowing Cloud Pills that the golden master gave him at the beginning, which was said to be the best to take when impacting the realm, and tried to impact the knot pill realm.

Unexpectedly, after taking ten Cloud Swallowing Pills in succession, although Wu Yan successfully reached the realm of the Great Perfection in the late stage of foundation building, there was no sign of the pill at all.

Just when Wu Yan was extremely confused, there was a change in the two insect breeding rooms that caught him off guard.

After the dragon viper in the "dragon viper" insect breeding room woke up, it was not surprising that it carried out devouring evolution. The 2,000 "dragon vipers" eventually evolved into 100 jet-black "ink vipers" that were more than two feet long, and the accident happened after these "ink vipers" evolved. After the successful evolution of one hundred "ink vipers", each "ink viper" died mysteriously en masse after laying four milky snake eggs. What's even more bizarre is that the corpses of those dead "Ink Vipers", under the action of the magic circle, turned into nourishment and were absorbed by the twelve remaining ink viper vines in this insect breeding room, so that these twelve ink viper vines also underwent abnormal evolution. After the mutation, the rhizome is only the size of a fist, and the vine is only the thickness of a finger, but it has four more vine whiskers, and the whole looks like an eight-legged spider growing in the ground, which looks really weird. However, these twelve mutant ink viper vines are real second-level ink viper demon vines.

This change is not the most surprising to Wu Yan. The changes in the other insect breeding room really made Wu Yan feel unbelievable and shocked.

The insect breeding array in this insect breeding room was originally arranged according to the special forbidden array for cultivating "Heaven Devouring Insects". After the incident of the "horned viper" devouring the golden-scaled seven-inch snake, Wu Yan was busy with the matter of knotting, and he forgot to adjust the magic circle of this insect breeding room, so that after the more than 100 "horned vipers" woke up, they rushed into the central insect breeding circle, causing the other four poisonous insects to also enter this magic circle at the same time.

Wu Yan retreated for ten days, and these five poisonous insects also underwent devouring evolution for ten days. When Wu Yan left the customs and appeared in this stone room, he was stunned to find that all the poisonous insects in the five magic circles on all sides were gone, and in the originally empty central insect breeding circle, there were one hundred and ten more fist-sized golden-shelled monster insects with jet-black markings and strange mouthparts.

The insect resembles a beetle, but it has a terrifying jet-black mouthpart that is more than half a foot long. Such a strange-looking poisonous insect really scared Wu Yan.

Except for the extra scare device and the black markings on the carapace, this insect is identical to the "Sky Swallowing Worm". The mouth of the "Sky Swallowing Worm" resembles a turtle and snake, although the end of the mouthparts of this strange insect is also shaped like a turtle and snake, but the extra half-foot-long jet-black mouthparts really make people feel disgusting and terrifying.

This insect has also just evolved successfully, and the magic circle in the entire insect breeding room has been broken by these newly evolved strange insects. The terrifying demonic aura emanated from the bodies of these one hundred and ten strange insects.

When the arrogant and stupid three times broke through the stone door of the stone chamber of Wuyan Cave Mansion, and broke into Wuyan Cave Mansion, he was also shocked by the more than 100 strange insects in front of him.

I'm afraid that no matter which foundation building period a monk is, he will also be stupid when he sees more than a hundred of such strange poisonous insects that exude the aura of second-level demon insects.

"Senior brothers, why are you all here?" Wu Yan asked in surprise, and at the same time took out the "green cow bag", and in a moment of thought, a cyan glow erupted from the green cow bag, covering this group of strange insects, and took it back at once. The demonic aura that rushed to the sky disappeared.

"Fourth, what are you doing? We thought you were in danger. What the hell is going on with those demon insects just now?" Mo Ao frowned.

"Hehe, that's a poisonous insect that I just cultivated, and it just evolved successfully, and even I didn't figure out what was going on. Hey, the three senior brothers are already in the realm of the Great Perfection in the late stage of foundation building? This is really good, have you tried to impact the Jiedan?" Wu Yan first snickered embarrassedly, and when he saw the realm of the three of them, he asked in surprise.

Feng shook his head with a smile and smiled bitterly, Mo Ao shrugged helplessly, and Tian Qi sighed. The three of them didn't speak, and they looked quite unspeakable. Suddenly, the faces of the three of them turned pale for a while, and their bodies were even more shaky, and they were about to pounce on the ground.

Wu Yan was suddenly startled, and hurriedly took out three of his own unique secret detoxification pills, fed one by one, and then quickly sealed the door of the insect breeding room, and helped the three of them out of their cave mansion and came to the main hall.

After helping the three of them to sit down, Wu Yan concocted a cup of diluted Yuehua Spirit Liquid for the three of them and fed them to drink. The three of them breathed for a while, and after a few moments, they each forced out a large mouthful of black poisonous phlegm, and then they each breathed a sigh of relief.

"Fourth, why is the poisonous gas in your cave so weird and powerful?" Feng Hanxiao is an alchemy master, he is very familiar with the medicinal properties of various elixir poisons, and he still hits the trick without realizing it, which shows how powerful the demonic aura left by the one hundred and ten poisonous insects just now.
