After Lu Chen walked into the depths of the cave for an hour again, suddenly a powerful demon beast aura appeared, and when he looked closely, it turned out to be a thousand-legged centipede about several zhang long, this centipede was a seventh-order demon beast, the whole body was frosty white, and the whole body was covered with cold air between flights, and it roared out from the depths of the cave in front of it, and at the moment of appearance, it raised its head to the sky and let out a long hiss, this hiss was like a thunderous rumbling echo in the cave for a long time, and the aura around the earthquake was constantly churning.

There are hundreds of pairs of white feet on the body stem of this thousand-legged frost centipede, densely packed, like a sharp knife, the head of this thousand-legged frost centipede has huge pincer teeth, revealing the cold glow of the forest, which is daunting.

This demon beast swayed its two long frost-white whiskers, and its eyes swept over Lu Chen coldly, and a cold meaning quickly swept over.

Lu Chen only felt that his body was cold, but with the rotation of the spiritual qi in his body, he easily dissolved the cold qi emitted by this demon beast.

The centipede was furious at the human monks who had intruded into its territory, staring at Lu Chen, revealing hatred again and again, as if it would never give up until it tore Lu Chen apart.

At this moment, the centipede roared, its body shook, and immediately a large white light emanated from its body, and suddenly turned into sharp ice edges, shooting towards Lu Chen.

"The Fire of Heaven and Earth"

Lu Chen took out several seventh-order fire talismans from the storage ring.

"Burn!" As these talismans dispersed, the ice edge emitted by the centipede was suddenly melted by the power of the flames, and at the same time, the centipede itself was surrounded by a sea of fire!

Although the defense power of the centipede itself is comparable to that of the early Yuan Infant, the attack power of several seventh-order magic runes is equivalent to the encirclement of several early Yuan Infant monks, the centipede's eyes showed a look of fear, its body was suddenly burned by flames from the outside to the inside, and the centipede's terrible hiss echoed in the cave, but after a while, everything was quiet.

I saw a fireball of several zhang size rising into the sky, illuminating the surrounding area of the cave, and then gradually extinguished, and the centipede burned up even the ashes!

All of this was done in an instant, and for Lu Chen, a master of array runes, it was just the price of a few talismans!

Lu Chen continued to walk forward, and after a while, he saw a pool of cold water in front of the cave.

Lu Chen found that the Tianjing ants that were originally hiding in the ice crystals in the storage ring were restless, presumably this pool of water was very useful to them, so Lu Chen summoned more than 60,000 Tianjing ants, and the Tianjing ants didn't care about communicating with their masters, and they all rushed into the pool at once.

Then, Lu Chen put the 100,000 Tianjing ant eggs into the pool water.

Lu Chen dipped his finger in a drop of pool water, to be precise, this was not water, it was a milky white viscous liquid.

"This ...... It seems to be a thousand-year-old ice milk!" After comparing the characteristic descriptions of the heavenly and earthly treasures in the ancient books he had read, Lu Chen recognized the origin of this pool of milky white liquid, and his face showed surprise, this is a treasure that even the Yuan infant monks are blushing.

Millennial Ice Milk, this is one of the rarer materials in the mortal world, but its effect is relatively rare, and it is only useful for demon beasts, especially ice demon beasts through swallowing and refining, which can not only make them reborn and change, but also increase the probability of advancement, because demon beasts, like humans, have a high mortality rate every time they advance.

In order to prevent other monks from exploring the cave here and disturbing the Celestial Crystal Ants to absorb and refine the thousand-year-old ice milk, Lu Chen meditated near the pond water to protect the Celestial Crystal Ants.

A month later, Lu Chen, who was meditating, felt the violent spiritual power fluctuations coming from the pool of thousand-year-old ice milk, and when he opened his eyes, he saw that there was only one-third of the thousand-year-old ice milk in the pool of dozens of square meters left.

Through mental induction, there was a joyful humming sound in the pool water, and countless heavenly crystal ants poured towards Lu Chen.

With a sweep of his divine sense, Lu Chen found that all the ant eggs had disappeared, and there were more than 30,000 more than 30,000 third-order Celestial Crystal Ants whose strength was comparable to that of the middle stage of foundation building, and the overall strength of these more than 30,000 Celestial Crystal Ants was slightly higher than that of a Yuan Infant Stage. The previous more than 60,000 third-order Heavenly Crystal Ants have been advanced, and their color is no longer snow-white, and they have become crystal clear, but there are only about 10,000 left, and their strength has skyrocketed from the middle stage of foundation building to a fourth-order demon beast comparable to the Great Perfection of Foundation Building, according to Lu Chen's estimate, the overall strength of these fourth-order Heavenly Crystal Ants should be slightly higher than that of a mid-Yuan Infant monk, and if he cooperates with these fourth-order Heavenly Crystal Ants, he believes that he can kill a mid-Yuan Infant monk in a few breaths.

The advancement of the Celestial Crystal Ant gave Lu Chen a stronger confidence in this Dragon Secret Realm.

Under the induction of his mind, the green scale demon python immediately rushed to Lu Chen's side, and Lu Chen asked it to absorb the remaining thousand-year-old ice milk.

Another month has passed, and the green scale demon python has completely absorbed these thousand-year-old ice milk, although it has not advanced, but the two bulges on its head are more prominent, and it is more likely to advance to Jiaolong in the future, and through mental communication, Lu Chen learned that the strength of the seventh-order demon beast green scale demon python has steadily surpassed that of the average human Yuan Infant late stage monk, if it was said that it could only compete with the human Yuan Infant late stage monk before, then now it has the strength to kill the late Yuan Infant monk.

Lu Chen put the Tianjing ant into the storage ring, let the green scale demon python follow quietly, and continued to walk forward.
