Thought of this.


    Su Lang immediately issued instructions to the system, trying to upgrade the Youtian Sword.


    however.


    The material is still not enough!


    It''s really not that Su Lang has too few materials, but that the materials needed for the evolution of the Youtian Sword are too high and too high!


    "The materials that can be synthesized have been synthesized."


    "It is impossible to evolve the Youtian Sword in a short time."


    "So, try to see if you can evolve other weapons?"


    "The Five Elements Sky Series, Space Rubik''s Cube, White Jade Emperor Pce, Luoyou Mirror, etc. are all auxiliary defensive emperor soldiers, so put them aside first."


    "Then try ughter Sky Sword Sheath and Xin Jue Wu Feng."


    "..."


    After thinking for a moment, Su Lang asked the system.


    It turned out that the ughter Sky scabbard was only a seven-great emperor soldier, and it needed more materials to evolve into a godless soldier, and itcked a few.


    Only the quasi-no-god-level heart has no edge, and the required promotion materials are enough.


    "Then tentatively decide that the heart will have no edge."


    "After Lin Fang''s hole cards are yed, I will decide whether to store the material in the Evolution Youtian Sword, or use the Evolution Heart Absolute Right now."


    After making up his mind, Su Lang dispatched his own clone to watch the ce where Lin Fang disappeared.


    at the same time.


    The center of Wushuang Building is underground.


    A huge cave almost formed a strange underground world!


    In this dim space.


    Growing all kinds of strange nts, they have extremely wide leaves, and the veins of the leaves show a fluorescent color.


    If you look closely, you can find that these fluorescent veins are actually a little dragon-shaped!


    And among these nts, there are also some spirit beasts.


    These spirit beasts are basically snake-shaped, and have some characteristics of dragons. They seem to be ferocious, elegant and noble, which is very strange.


    Of course, there are also creatures that are not snake-shaped.


    But these ‘different’ creatures can only be reduced to the lowest level of food here!


    Because those dragon-snake-shaped spirit beasts are very powerful, not only at the fairy level, but even at the emperor level!


    And these snake-shaped creatures are entrenched on some nts, stones, and cave walls, and the heads of dragons and snakes face the same direction.


    They have horrifying mouths wide open, and they seem to be sucking something.


    at this time.


    Wow!


    A st of falling rocks fell.


    It turned out that Lin Fang came to this underground space from the ground!


    "Hiss!"


    Seeing Lin Fang, countless creatures in the shape of dragons and snakes crawled to the ground.


    This is because Lin Chang possesses the "Dragon Willow Dao Fei" and his cultivation is strong, which has caused natural terror pressure on these creatures with extremely thin dragon veins.


    Lin Fang looked around, not looking at the spirit beasts in the shape of dragons and snakes. After checking the direction, he flew straight to the destination.


    With a quasi godless speed, he reached under an extremelyrge stone pir almost instantly.


    This stone pir is very huge, it looks like the sky pir of this underground world, standing on top of the earth, supporting the sky and opening up this underground world.


    On the stone pirs, there are also dragon-like fluorescent veins!


    And these fluorescent veins are brighter and thicker.


    The strange nts surrounding the stone pirs also grow taller and possess stronger spiritual pressure.


    Follow the fluorescent dragon veins on the stone pirs.


    Lin Fang flew up, and soon came to the middle section of the stone pir.


    However, all the stone pirs in this section have been covered by strange fluorescence.


    A trace of fluorescence flows down from this stone pir, forming the dragon vein-like patterns below.


    Here is the source of the strange fluorescence of the entire underground world!


    "Master!"


    "The disciple hase to see you!"


    Lin Fang knelt at this fluorescent stone pir in the air, then turned into streamer and rushed into the stone pir!


    The tough stone pirs containing a lot of dragon-like fluorescence, in front of Lin Fang, automatically lined up like soft mud, exposing the passage.


    Follow the channel.


    Lin Fang arrived at the center of Shizhu!


    This ce has be an ocean of dragon-pattern fluorescence, with dazzling light on all sides!


    In the center, there was a tall, crystal-clear man suspended quietly.
