Come to the fifth day of this monster forest.

In the evening, a swift figure flickered through the dense forest, and the intricate terrain and dense thorns did not affect him in the slightest.

Moving the wide rocks and passing through the long tunnel, Chen Huai finally rushed back to the yellow scorpion's nest before the night fell.

After returning to the shelter, Chen Huai began to count the gains in the space ring today, and then a little smile couldn't help but appear on his face.

Chen Huai's harvest in the past two days was also quite good, four pieces of first-grade spiritual material Zhu Yantie, three second-grade spiritual grass cooking grass, one fourth-grade spiritual material blue gilt bamboo, three second-order demonic beasts and two third-order demonic beasts, and a number of ordinary herbs.

Although he killed two third-order demonic beasts, those two demonic beasts were wind-based insect demonic beasts and water-type snake demonic beasts, and the two crystal nuclei obtained were not suitable for Chen Huai to open source, so Chen Huai was unable to cultivate spiritual power for the time being.

Even so, Chen Huai was not anxious, after all, compared to the previous search for the thunder and fire dual system exercises, the search for the thunder and fire crystal nuclei of the third order was much simpler.

After Chen Huai simply ate the dry food, he selected the spirit grass spirit material to be refined in the space ring, and the four-grade fire silkworm crystal had already been refined yesterday.

I don't know if it's Chen Huai's illusion or what, Chen Huai feels that the refining of this spiritual material and spiritual grass seems to be much simpler than others.

For example, when Wei Ling'er had previously refined the four-grade spiritual material Xunfeng Sand, it took a total of ten days.

And Chen Huai's four-grade fire silkworm crystal took two days to complete the refining, although this fire silkworm crystal is composed of two third-grade spiritual materials, but there is no reason why it will be so fast.

What Chen Huai didn't know was that the inexplicable exercises taught to him by this strange gray bead were extremely suitable for Chen Huai, making Chen Huai far faster and more efficient than others when he operated the exercises, cultivated spiritual power, and refined spiritual materials and spiritual grass.

After the refining of the four-grade fire silkworm crystal was completed, the Flame Spear Martial Soul still did not raise its grade, but this was also quite normal.

After all, Chen Huai's Yan Xingyan Spear was originally a top-level martial soul, which was quite a good martial soul talent, and it was not so easy to improve the martial soul level.

If this mere four-grade spiritual material can make the earth-level martial soul rise to the heavenly level, then wouldn't this Shenwu Continent be full of heaven-level martial soul soul masters.

However, although this Flame Spear did not raise its rank, these four grades of Fire Silkworm Crystal still brought it a lot of benefits.

After several selections, Chen Huai chose his favorite items, and then the silver ring flashed between his fingers, and a delicately shaped jade bottle appeared in Chen Huai's hand.

This jade bottle was not the Enyan Slurry that Chen Huai had received from the treasure house of Yanming Academy, but one of the spiritual materials that He Ningqiu had given to Chen Huai before.

Chen Huai opened the jade bottle, and then a strong force of qi and blood surged out, and the entire cave was instantly filled with a strong smell of blood, and vaguely, it seemed that the roar of the beast could be heard in this jade bottle.

The spiritual material presented in this jade bottle is the essence blood of a demonic beast, the essence blood of the fifth-order peak demonic beast Red Muscle Dragon!

This red-tendon dragon is a fire-type dragon type demonic beast, which belongs to a high-level bloodline demonic beast, and it can become a seventh-order demonic beast at the highest level when it becomes an adult.

This red tendon dragon essence blood contains extremely rich fire-based spiritual power, and there is a strong power of qi and blood in the essence blood, which can exercise muscles and bones and improve physical fitness.

In addition, the most important point is that the power of the bloodline in the blood of this red tendon dragon essence is very likely to help Chen Huai comprehend the bloodline supernatural power.

This is different from the Xuanhuo Red Dragon Claw that Chen Huai saw at the Wanjin Chamber of Commerce before, the Xuanhuo Red Dragon Claw only had a small amount of blood, but what was in this jade bottle was the real essence blood of the Red Muscle Dragon.

This means that Chen Huai has a lot of possibilities to comprehend the bloodline of this red muscle dragon, and with the essence blood of this red muscle dragon, he can greatly improve Chen Huai's physique and increase the endurance of the spirit martial arts Qinglei Shadow.

Chen Huai immediately crossed his legs, closed his eyes, held the delicate jade bottle tightly in his right hand, formed a magic seal with his left hand, and used the spiritual power in the dantian, pouring into the blood of the red tendon dragon essence through the jade bottle, and began to concentrate on refining his mind.

As Chen Huai gradually entered the refining state, the sound of breathing became more and more steady and long.

At this moment, a strange black shadow suddenly appeared in the cave without a sound, standing quietly in front of Chen Huai.

With Chen Huai's spiritual power, he didn't even detect the appearance of this black shadow at all, and he was still concentrating on refining the red tendon dragon essence blood in his hand.

The black shadow looked at Chen Huai, who was refining, and with a slight wave of his hand, several faint lights like fireflies flew out and poured into Chen Huai's body.

The moment the faint light flew into Chen Huai's body, the surging spiritual power in Chen Huai's body, as well as the steady breathing, immediately stopped, as if the time stop button had been pressed.

The black shadow then took out a delicate and small red jade bottle, which contained a crimson-gold liquid that surged with a more powerful aura than the blood of the red-tendoned dragon.

The black shadow poured all the red gold liquid into the jade bottle in Chen Huai's hand, and the strange liquid mixed with the red tendon dragon essence blood, instantly becoming extremely hot, and erupted into an extremely strong spiritual power fluctuation.

The black shadow immediately formed several magic seals, transmitting the pure spiritual power into the jade bottle, and the boiling liquid instantly calmed down.

I saw that the liquid that was about to overflow in the jade bottle gradually decreased, and it became the size when it only stored the blood of the Red Muscle Dragon Essence before, and together with the breath, it also became exactly the same as before.

Just when this black shadow hand knot magic seal was transmitting spiritual power, the strange broken bone in Chen Huai's space ring was flickering with a faint light due to the appearance of that red golden liquid.

After the black shadow finished transmitting the spiritual power, he looked at the ring between Chen Huai's fingers with a little surprise, as if he had discovered the change of this mysterious broken bone through the spatial ring.

The black shadow then tapped Chen Huai's space ring, and the severed bone actually flew out of the ring directly and floated in front of the black shadow.

The black shadow looked at the broken bone in front of him with curiosity, this was a strange broken bone the size of a finger, and the whole body was as red as jade, and at this time, it emitted bursts of bright red and blood-like demonic light.

The black shadow operated spiritual power, driving the red jade-like broken bones to float above the mixed essence blood, and the red light shining on the broken bones gradually condensed and projected into the essence blood.

After the mixture, the red tendon dragon essence blood seems to have undergone some indescribable changes, obviously the breath, quantity, spiritual power fluctuations, etc. have not changed, but there is a different feeling.

After releasing the red light, the surging light on the severed bone immediately stopped, and the black shadow did not take the strange broken bone, but placed the broken bone in Chen Huai's arms.

Immediately, the black shadow waved his hand lightly again, and several faint rays of light lit up from Chen Huai's body, turning into a little starlight and flying back into the black shadow's hand.

As this light retracted, the black shadow immediately disappeared in place strangely, and the spiritual power in Chen Huai's body also flowed again, exuding even breathing.

Chen Huai didn't seem to notice the change in his talent, as well as the change in the essence blood of the Red Muscle Dragon in his hand, and he was still concentrating on refining the essence blood.

The sound of even and long breathing echoed in the cave, and the appearance of the black shadow and everything it did seemed to have never happened, if it weren't for the broken bones in Chen Huai's arms.......
