The lake is very deep, Wu Fan dived for a long time, only to see a black reef at the bottom of the lake, to here, the surrounding light has become extremely dim, Wu Fan blessed himself with a heavenly eye technique, everything at the bottom of the lake, is also presented in front of him.

In the place where Wu Fan is about ten zhang away, there is a pitch-black hole, the hole is more than ten zhang in size, the lake water to the mouth of the cave, but it is naturally divided into two halves, and wants to flow on both sides.

As soon as his body moved, Wu Fan swam to the entrance of the cave without hesitation, flashed slightly, and disappeared into the lake the next moment.

Different from the darkness outside, the inside of the cave was bright, Wu Fan looked up and found that he was standing in a cave about a hundred zhang in size at this time, and the cave was covered with a kind of blue spar.

Wu Fan's attention was not on these dreamlike spars, but stared at the center of the cave, and a flash of horror flashed in his eyes, because where was there a huge turtle shell with a size of more than fifty zhang.

The whole body of the turtle shell is dark black, and when the palm is pressed, there are bursts of cold breath from above, and the lines between the turtle shells are also extremely clear.

"What is this, it seems, it seems to be the shell of the Xuanshui turtle before, but why is it here? ”

A trace of doubt flashed in Wu Fan's eyes, and he muttered to himself.

"Now I finally know, why the Xuanshui Turtle that day was not the opponent of the Python, can comprehend the realm of water, and the cultivation should not be so low, now it seems that the previous Xuanshui Turtle should have just experienced the catastrophe of transformation, and before he could consolidate his cultivation, he encountered the Python, and this huge turtle shell should be what was left behind when the Xuanshui Turtle transformed. ”

Luo Tianli's faint voice came from his divine sense, and at the same time, a white light flashed on Wu Fan's wrist, and Luo Tianli emerged from it.

"I see, it seems a bit impossible to take away such a large piece of turtle shell. ”

Hearing Luo Tianli's explanation, Wu Fan's palm brushed the huge turtle shell again, and the mana in his hand flowed slightly, but he found that the turtle shell did not move at all, and it seemed that this thing should not be able to shrink it through spells.

"Take it away, why do you take it away, don't you have a shield on your body, don't you just refine this turtle shell and your shield into a magic weapon." ”

"What the predecessors said is indeed a good way, but to refine the corresponding magic weapon, there must be a refining method, and the younger generation does not have this refining method. ”

"Cut, since the old man said so, the way is naturally to find a good one, and give it to you. ”

Seeing Wu Fan's expression, Luo Tianli also rolled his eyes, and then with one move, he took out a blank jade pendant from Wu Fan's purple gold bracelet, copied the refining method into it, and threw it to Wu Fan.

"Hehe, thank you seniors. ”

Wu Fan smiled, then put the jade pendant on his forehead, and looked at it carefully, the refining method recorded in the jade pendant was not very profound, Wu Fan just took a general look, and he also roughly understood the principle.

To put it simply, this is also a magic weapon refining method, but compared to the real refining magic weapon, it is much simpler, and the materials required in it, in addition to this turtle shell, there are some other materials, and Wu Fan is also very easy to find in the purple gold bracelet.

After comprehending the method of refining, Wu Fan then walked to the huge turtle shell, turned his palm over, and there was a wisp of gray-black flame in the palm of his hand, and with a pinch of one hand, the flame in his hand suddenly rose, and then turned into a huge ball of flames, wrapped the turtle shell, and began a long refining journey.

Unconsciously, a month passed quietly, during this period, Wu Fan had been refining turtle shells in the cave at the bottom of the lake, and now, the turtle shells that were originally more than fifty zhang in size have become only zhang in size.

After a month of uninterrupted refining, Wu Fan was now able to control the size of this turtle shell, and with one hand, he had a small black shield in his hand, which was the same black shield he had obtained before.

The magic in his hand changed, the small black shield in his hand flashed wildly, becoming the same size as the turtle shell, the shield slowly flew in front of the turtle shell, and Wu Fan controlled the spiritual power in his body, so that the two shields began to slowly fuse.

Circles of visible ripples spread out from the shield and turtle shell, Wu Fan flicked his fingers in succession, and one after another flew out of his fingertips, and then merged into the shield in front of him, and after a while, the black shield and the turtle shell finally merged into one, forming a huge shield.

With a flick of a finger, a drop of essence blood flew out from the fingertip, and then the magic in Wu Fan's hand changed, and the essence blood turned into a blood-colored rune, flashing slightly, and blending into the shield.

With a sigh of relief, Wu Fan's face also leaked a little tiredness, after a month of continuous refining, even if Wu Fan's mana in his body far exceeded that of a monk of the same level, he felt a little unable to support it at this time.

Fortunately, everything went well, the efforts were not in vain, more than a month of refining, Wu Fan can be regarded as refining the first magic weapon of his own, thinking of this, Wu Fan was also faintly excited in his heart, but he did not put away the newly refined magic weapon.

Took out a few pills from the purple gold bracelet and took them, and began to recover the mana deficit in the body, although the magic weapon was successfully refined, but Wu Fan did not have much confidence in this magic weapon refined for the first time, and now he still had to recover the mana, and then try the power of this magic weapon in his heart to rest assured.

Time has passed for a stick of incense, after absorbing two pills, the mana in Wu Fan's body finally recovered about fifty percent, slowly opened his eyes, staring at the black shield in front of him, Wu Fan did not grind, one hand clenched his fist, and a golden fist smashed into the shield.

When a soft sound came, the surface of the shield, layers of ripples kept shaking like water waves, but the shield was still not moving, and it didn't look abnormal at all.

"Well, it's not bad, the wheel defense power is indeed a magic weapon at the top of time, since it is a magic weapon that I refined myself, let's call it Xuanshui Shield." ”

Nodding with satisfaction, he put away the black shield, and then flashed his body and shot away to the outside of the cave entrance.

Since Wu Fan cultivated the Vajra Hades Duel, he has refined two kinds of essence fire in a row, plus the strengthening of the body after cultivating the Fire God Duel, Wu Fan's current strength has reached an extremely terrifying level, and it is conservatively estimated that if Wu Fan runs the Vajra Hades Duel with all his might, his hands should have at least ten thousand catties of strength.

And such a powerful power, against this Xuanshui shield, it can only slightly shake this treasure, which shows that the defensive power of this Xuanshui shield is not ordinary.

Leaving the lake, Wu Fan did not stop any longer, all the way to the extreme west, the light did not stop at all, and disappeared at the end of the wilderness in a blink of an eye.
