Having made up his mind, Chang Shan thought for a moment, and while recovering the true yuan, he felt the state of the Sumeru Immortal Mansion.

After feeling the state of the Sumeru Immortal Mansion, Chang Shan found that even if he did not absorb the spiritual power in the Sumeru Immortal Mansion, the spiritual power of the Sumeru Immortal Mansion was constantly being consumed.

"It seems that it will not work if you want to use the Sumeru Immortal Mansion to stay in the Chaos Secret Realm more. ”

A look of disappointment flashed in Chang Shan's eyes, he took a deep breath, collected his spirit, and felt the breath of the demon refining bell concentratingly.

This time, the Demon Refining Bell was destroyed, and it did not enter a deep sleep state, as long as it had enough spiritual power, it could recover quickly.

After pondering for a while, Chang Shan took out the corpse of the original beast that he had killed, which resembled a snake, and controlled the demon refining bell to refine it.

When the Demon Refining Bell began to refine the corpse of the snake, Chang Shan found that the benefits of the corpse of the snake to the Demon Refining Bell were exactly the same as the benefits of the Mixed Yuan Stone to the Demon Refining Bell.

"The Demon Refining Bell refines the living primordial beasts, and the effect of replenishing consumption should be better. ”

Chang Shan's eyes flashed, and he didn't take out the inner pill that turned into a snake, and directly controlled the demon refining bell to refine the entire corpse.

Refining the corpse of a snake, the demon refining bell has not recovered, and the thousands of starlight in the bell are very dim, even if Chang Shan urges the demon refining bell to the extreme, those starlights will not turn into the shape of demon beasts.

After thinking about it, Chang Shan felt that if the corpse of the giant fish proto-beast was refined, it would be difficult for the demon refining bell to recover, so he dispelled the idea of refining the corpse of the giant fish proto-beast and concentrated on restoring the true yuan.

The battle between Chang Shan and Zhou Changyong was extremely thrilling, but it didn't take long, Chang Shan Yuan Shen was injured, but Zhen Yuan didn't consume much, he only meditated for an hour and a half, and Zhen Yuan returned to his peak state.

After thinking for a moment, Chang Shan left the Sumeru Immortal Mansion.

The grassland was still calm, and there was not a single primordial beast in sight, let alone a cultivator.

Chang Shan glanced around, and without a fixed target, he continued to fly forward in the previous direction. Flying forward for less than half an hour, he once again saw a cave with gray grass covering the entrance of the cave.

This time, Chang Shan didn't hesitate and went straight in.

Just like the cave that Chang Shan had visited before, Chang Shan flew forward in the cave for nearly a stick of incense, and did not find a single original beast or any spiritual object.

He flew forward for about a stick of incense, and suddenly his eyes opened up, and he came to a relatively large underground space.

This underground space, 378 zhang high and more than 100 zhang in circumference, is connected to seven caves.

The environment here is very similar to the disappeared Land of the Sealed Dragon, and when he came here, Chang Shan naturally thought of the experience of searching for treasures in the Land of the Sealed Dragon.

Thinking of his experience back then, Chang Shan naturally felt the concentration of the chaotic evil qi in the other six caves.

The chaotic evil qi was harmful to cultivators, and Chang Shan judged that the chaotic evil qi in that cave was relatively strong based on the strength of the chaotic evil qi that made him feel uncomfortable.

Chang Shan figured out that the chaotic evil qi in the cave was a little thicker, and flew directly to the cave.

He flew forward another seven miles or so, and suddenly stopped.

In front of him was an underground space three or four times larger than the underground space he had just visited, and the underground space was crowded with primordial beasts that looked like dragons.

These primordial beasts, with the most powerful breath, were about the same as the cultivators in the late stage of Lan Dan.

Woo!

Woo!

Nearly a hundred proto-beasts roared at Chang Shan, and there was a warning in the roar, but Chang Shan could see fear in their simple eyes.

Chang Shan hesitated for a moment, turned into a gluttonous body, and swallowed all the nearly 100 original beasts.

He is not a person who loves to kill, but he has his own understanding of life and race, and if he was in the time of the ancient demon war, he might also be like the blood-clothed ancestor, a killing god.

In fact, in order to protect themselves and ensure the inheritance of the human race, the great supernatural powers in ancient times were all god-killing gods, but most of them did not use the killing intent to enhance their strength, so the only one who died under the killing intent they cultivated was the blood-clothed ancestor.

Chang Shan swallowed those primordial beasts, and instead of dealing with them with the chaotic qi in his body, he spit them out one by one and refined them with the Demon Refining Bell.

After refining nearly a hundred primordial beasts, the Demon Refining Bell not only fully recovered, but also slightly increased in power.

The Inner Pill of the Primordial Beast needs to be refined into an elixir with some spiritual grasses existing in the land of the Seven Prefectures, which can be used to replenish the True Yuan, and cannot be swallowed directly.

This is because the Inner Pill of the Primordial Beast cannot be taken directly, and it will destroy the balance of the five elements in the cultivator's body.

For most demon beasts, there is no balance of the five elements in their bodies, and of course, there is no such thing as destroying the balance of the five elements in their bodies, so the demon beasts can not only take the inner pill of the original beast, but also use it to break the bottleneck of cultivation.

The Ten Thousand Immortal Array in Changshan's Demon Refining Bell is arranged with the essence of the demon beast, and the inner pill of the original beast, and even the entire original beast, can be used to purify and improve the essence of the demon beast, and of course, it can also be used to enhance the power of the demon refining bell.

When Chang Shan controlled the Demon Refining Bell to refine the Inner Dan of the original beast that resembled a snake, he didn't feel this effect of the original beast's Inner Dan, but because the consumption of the Demon Refining Bell itself was too great, the Ten Thousand Immortal Array was not at its peak, and Chang Shan couldn't feel the change in the power of the Ten Thousand Immortal Array.

After thinking about the reason for the increase in the power of the Demon Refining Bell, Chang Shan decided that if his strength was enough to deal with it, he would not let go of any of the original beasts he saw.

Chang Shan pondered for a while, turned into a human body, suppressed the distracting thoughts in his heart, and continued to fly forward.

After flying forward for less than a cup of tea, Chang Shan encountered a group of proto-beasts again.

The overall strength of this group of primordial beasts was stronger than the group of primordial beasts that Chang Shan had just encountered, however, the strength was very limited, and the aura of the primordial beast with the strongest breath was also obviously weaker than that of the Zidan stage cultivators.

The old technique was repeated, and Chang Shan used the demon refining bell to refine this group of original beasts.

Almost every time he flew seven or eight miles forward, Chang Shan would encounter a group of proto-beasts, and after nearly a hundred miles of progress, Chang Shan's path was blocked by a proto-beast whose breath was a few points stronger than him.

The body of the protozoa is large, and its back is almost attached to the top of the cave.

Whining!

The original beast did not immediately attack Changshan, but sent a warning to Changshan.

Chang Shan's mind turned sharply, and he pointed at the center of the original beast's eyebrows.

Seeing that Chang Shan launched an attack on it, the proto-beast suddenly opened its mouth and sent out an extremely strong suction force towards Chang Shan.

Chang Shan followed the suction of the original beast into the mouth of the original beast, and then, with the help of bone wings, stabilized his body for a moment, and stabbed straight up with a sword qi condensed by the true fire of the sun.

The Sun True Fire was extremely domineering, and its condensed sword qi directly pierced the head of the original beast.

The proto-beast's body twitched violently a few times, and without any violent reaction, it completely stopped moving.

Chang Shan got out of the original beast, took out a storage ring to put away the body of the original beast, and then put the storage bag into the Sumeru Immortal Mansion.

After continuing to walk forward for a while, Changshan came to a space with a large area.

"Why don't you have a single proto-beast?"

Chang Shan stood in place and pondered for a while, then continued to fly forward.

After walking more than 100 miles, Changshan came to a huge space with a radius of twenty-two or three miles.

This space is not only large, but also the space is not monotonous, there are all kinds of strange-shaped stone cones as hills, and there is a lake with an area of more than ten miles.

Everything in the Chaos Realm is gray, and so is the water in this soul.

Chang Shan swept around, frowned, and flew to the lake.

On the edge of the lake, there are some footprints of the original beast, and the roots and leaves of some plants can be seen in the footprints.

The reason why Chang Shan went into these caves where the original beasts most likely lived to hunt for treasure was that he thought that the place where the original beasts gathered was the place where the spiritual creatures were located.

As it turned out, his guess was correct, but, alas, before he came to the place where the spirit object was, all the spirit objects were taken or destroyed by the original beast.

"Knowing how to destroy these spirit grasses, the original beast is not without any intelligence. ”

Chang Shan muttered to himself and searched along the lake.

After walking around the lake, Changshan did not find a section of a vigorous rhizome.

"It's a pity!"

Chang Shan sighed, his gaze fixed on a stone cave that was completely blocked by a collapsed stone body.

The original beast that lives here must have escaped through that stone cave.

Chang Shan pondered for a while, his body moved, and he flew to the mouth of the stone cave.

Generally speaking, only when a cultivator enters the newly discovered Chaos Secret Realm, he will unscrupulously kill the original beasts living in the Chaos Secret Realm, so as to ensure that the original beasts in this Chaos Secret Realm will not threaten the cultivators who have come in to practice because of the huge number.

When most of the treasures in a Chaotic Secret Realm are found to be looted by the forces of the Chaotic Secret Realm, cultivators who are searching for treasures in the Chaotic Secret Realm will generally not kill the original beast at will, because the lower grade Returning Yuan Dan that is suitable for cultivators in the Purple Pill Stage needs to be refined with the inner pill of the original beast whose breath and strength are comparable to those of the cultivators of the Purple Pill Stage.

The reason for not wantonly killing the original beast is to obtain more original beast inner pills that are suitable for refining the Yuan Dan.

As a result, many cultivators turned the Chaos Secret Realm into a breeding ground.

Chang Shan knew that if he hadn't taken the opportunity to enhance the power of the Demon Refining Bell with a large number of primordial beasts this time, then if he wanted to have a large number of primordial beasts to cultivate the Demon Refining Bell, he would have to wait until the next Chaos Secret Realm was discovered.

Therefore, Chang Shan decided to chase the original beasts that had escaped.

Standing at the entrance of the cave, Tsuneyama sank into a state of merging with the earth beneath his feet, and felt the situation of the blocked cave with the help of the earth's pulsations.

When Chang Shan sank into a state of merging with the earth under his feet, he was surprised to find that there was a mixed element stone spirit vein under his feet, and the number of mixed element stones contained in this mixed element stone spirit vein was extremely large, and for a while, he couldn't count them.

"This spirit vein should be the real Mixed Yuan Stone Spirit Vein!"

Chang Shan found countless mixed element stones, and naturally immediately dispelled the idea of chasing the group of primordial beasts, thinking about how to dig up all the mixed element stones he found as quickly as possible.

Just as Chang Shan was thinking about how to dig up the mixed yuan stone, the ground under his feet began to shake, and the earth and stones above his head began to fall down, and the huge underground space was obviously about to collapse.
