The surrounding demons wanted to escape, but because of the limitations of the trap, the speed was extremely slow, Mu Chen's mind moved, not in a hurry, compared the difference in strength between the two sides, and summoned the Michen Silver Sword to kill the demons and demon beasts on the bright face one by one. As for the demons who hide deeper and don't leak any breath, there is nothing they can do.

After arranging the compound formation and ensuring that it is correct, a concealment formation is arranged again outside it to hide the traces of the broken sword. Ensure that the demons and monsters in the outside world cannot detect this place in a short time. Finally, place the Spiritual Golem Dust in the outside world, let it be on guard, and kill it as soon as it finds any traces of the demon.

After doing all this, Mu Chen put all his attention on the broken sword in front of him. Mu Chen had a faint premonition in his heart, it would take at least three days, or even longer, to completely figure out the broken sword.

Mu Chen crossed his knees, concentrating and calming his breath, mobilizing the incomplete Canghai immortal inscriptions in the sea of knowledge, wanting to communicate with the broken sword and form a connection.

The pale blue mutilated immortal inscription flickered by as if it had the same origin and merged into the broken sword, and the broken sword flashed a dark blue light slightly, and then fell silent, not forming a connection with the wood dust, and the connection between the mutilated inscription and the wood dust was also cut off in an instant.

For a while, Mu Chen's perception of the water attribute continued to decrease, as if a veil was covering his eyes, and the instantaneous water attribute spell became a luxury. The disappearance of the mutilated immortal inscription directly weakened the strength of Mu Chen's by three percent, or even more.

Mu Chen's heart was flustered, and he wanted to probe his spiritual sense into the broken sword, find the broken inscription, and bring it back. However, the moment his spiritual sense penetrated into the body of the broken sword, it directly hit the wall and could not go deeper.

Mu Chen forced himself to calm down, squeezed out a drop of blood and smeared it on the broken sword, the broken sword slowly absorbed this drop of blood from Mu Chen, but the broken sword did not have any connection with Mu Chen, and still did not perceive the existence of the broken sea inscription.

Mu Chen squeezed out a drop of essence blood in his heart, and the broken sword gradually absorbed it, but it was still the same. Mu Chen recited the mantra of the refining instrument, trying to forcibly create a connection with the broken sword, but still failed. Activating the alchemy mantra is still useless. Mu Chen tried several methods, but the final result was in vain.

Mu Chen was helpless, and asked for help from the painter system in his mind.

"What is this sword? How can I mobilize this sword, and how can I take out the broken immortal inscription that is fused within?" Mu Chen asked three questions in a row. Xu was aware of the urgency of Mu Chen, panicked, and the artist system did not ask for Mu Chen's aura, and replied directly:

"This is a broken sea slate, which was refined into a broken sword by the power of the great power countless years ago, and its power is shocking, but because of its age, and the degree of brokenness is quite high, the breath of the sea is not obvious, and for various reasons, it cannot be controlled by the monk, it has become a chicken-like item, and the only use is that the strength of its magic weapon is comparable to that of a defensive magic weapon at the peak of the fourth order, and non-ninth-order appraisers cannot investigate its origin. ”

Mu Chen suddenly, a picture appeared in his mind: a certain tutor in the academy may have inadvertently obtained this broken sword, because he could not see through its origin, so he regarded it as an ordinary mutilated magic weapon, which was tasteless to eat, and it was a pity to abandon it, so he threw it into the cave for the students to fight for.

"If the host wishes to mobilize this mutilated sword, it must first obtain its approval. However, because the mutilated sword was too badly damaged, the spirit inside it was not visible, so it could not be recognized by blood, and the spiritual sense could not penetrate into it. Mu Chen nodded, looking into the joints within.

"If you want to take out the mutilated immortal inscription inside, you must obtain the approval of the mutilated sword before you can take it out. Because the damage caused by the mutilated sword was too severe, the immortal inscription entered it to conceive and nourish it, hoping to awaken the spirituality within it. Without interference, until the spirit within the mutilated spirit is awakened, the mutilated immortal inscription will not come out of it. ”

Mu Chen nodded as he listened, knowing everything about the broken sword in front of him.

"How do you get the Broken Sword approval?" asked Muchen.

If he can get the approval of the broken sword and awaken the spirituality in it, then Mu Chen will harvest a spirit treasure, and it will be an offensive spirit treasure, and his strength will be greatly increased. How could Mu Chen give up such a temptation?

"Ding, do you agree to spend all your spiritual energy to get the answer? ”

"Agreed. Mu Chen was a little weaker, and the voice of the painter system sounded.

"Reciting the Spiritual Determination can form a faint connection with the Broken Sword, enter the Broken Sword Space to gain its recognition, and awaken its spirituality. The mantra of the spiritual heart is as follows: heart and spirit are united, the soul is condensed, the stars and dreams are the source, and the remnant dream is the soul ......"

Mu Chen nodded and recited without hesitation. Once, twice, three times, Mu Chen gradually felt a touch of connection with the sword of the broken sword, and he breathed a sigh of relief in his heart, speeding up the recitation, when Mu Chen's recitation of the soul was decided to the ninety-ninth time?

Whoosh, a deep blue vortex emerged, absorbing the wood dust into it.

The aura of Mu Chen's breath disappeared briefly in the Cave Heaven Spirit Treasure, and the head of the outside monk department ordered the veteran to see everything in his eyes, and his heart was shocked, but with a wave of his hand, he covertly arranged a high-level formation to cover the fact for Mu Chen, avoid it from being discovered, and wait for Mu Chen to come out of the broken sword.

The head of the department ordered the elder to see through the broken sword, but it could contain a space inside? How could it be a mortal thing, at least a spiritual treasure. The head of the department fell into deep thought and recalled, this broken sword seemed to have been thrown into the cave by the head teacher of Hanhai, and afterwards, I had to ask where this broken sword was found.

Mu Chen? I don't know if he can obtain this Dao Spirit Treasure? Once he obtains it, then Mu Chen will have absolute self-preservation power in this Cave Heaven, and in the face of the Demon Patriarch, the Nine Dao Squad Leader, he will be completely worthless, and may be able to have the power to kill.

The head of the department couldn't help but come alive with the thoughts of the elder.

The tutors of the academy, the demon beast spirit sense, and the onlookers did not notice this small action of the old man. It was a spirit body of the Heavenly Dragon, and because of factors such as strength and perception, it was not perceived. Inside the Cave, the deeply hidden and escaped demons gather their men to slay the wood dust and seize the broken sword.

However, when he followed the coordinates left earlier, he suddenly found that there was an endless plain in front of him, and there was no trace of the broken sword and wood dust. A closer look still yielded nothing. Investigate several times?The demons left in confusion.

Inside the broken sword, Mu Chen opened his eyes in confusion and looked around. In the stele of Canghai, the wood dust turned into the sea, experienced the artistic conception of the sea, and finally comprehended the incomplete Canghai immortal art. And the scene in front of him at this moment made Mu Chen's heart stir and he couldn't forget it.

The turquoise sea is facing depletion, and large swaths of the sea floor are exposed and appear to be dry. Fish, shrimp, coral, patches of death, fishy, disgusting smell straight to the tip of the wood dust's nose. The sea, which was supposed to be vibrant, is now twilight.
