Moreover, Xu Chuan also discovered that it is not just the Dragon Empire.


    Even the Red Sun Empire, the Bald Eagle Empire, and the Fur Bear Empire focused on the Void Defense Line.


    It seems that in the endless void, there is an enemy coming soon.


    What exactly can make the four empires in the main world abandon their past grudges and tacitly aim their defense at the outside?


    Xu Chuan thought for a long time, but he couldn''t come up with anything.


    I simply didn''t think about it anymore.


    No matter how the pattern of the main world changes, improving one''s own strength is Xu Chuan''s only goal at present.


    After all the major divine beasts have been upgraded, the prehistoric divine realm has also completed the annexation of the divine realm territory.


    Xu Chuan immediately controlled the prehistoric divine realm and headed to the next resource point.


    Nowadays, Xu Chuan still lacks the ninth-level fire element energy core.


    If the next resource point still does not have the ninth-level fire element energy core that Xu Chuan needs, it will be embarrassing.


    A few hours later.


    Xu Chuan controlled the prehistoric divine realm to come to the second resource point.


    After Xuchuan had cleaned up before, there were no imperial garrisons here, which was very clean.


    Xu Chuan was familiar with the control of the prehistoric divine realm to clean the seventh-level and eighth-level planes on the periphery.


    At the same time, a bunch of elemental energy cores of the seventh and eighth level were obtained.


    Among them, there is an eighth-level gold element energy core.


    This is exactly the attribute required for the White Tiger to upgrade!


    With this eighth-level gold element energy core, Xu Chuan was able to promote the white tiger to a ninth-level species.


    Now, there is only the last ninth-level plane left in front of you.


    Xu Chuan controlled the prehistoric divine realm and soon completed docking with this ninth-level plane.


    "System, scan the number of elemental energy cores!"


    Xu Chuan said to the system


    "Ding! The system is scanning..."


    "Ding! A ninth-level elemental energy core was detected!"


    "Ding! A core of eighth-level elemental energy was detected!"


    …


    Looking at the detection data given by the system, Xu Chuan''s brows couldn''t help but frown.


    There is only one ninth-level elemental energy core outside this ninth-level.


    Compared with the few ninth-level planes that Xu Chuan had captured before, this number is too small.


    In other words, Xu Chuan only has one-fifth chance.


    Anyway, give it a try.


    "Green Dragon! Phoenix!"


    Xu Chuan descended the oracle.


    Like before, the Qinglong and the Phoenix rose into the sky and began to sweep the ninth-level plane.


    It is worthy of being a holy beast with powerful bloodline power and enough to forge a magical weapon.


    Ordinary ninth-level species are no match for Qinglong and Phoenix.


    The thunder of robbery and karma fire descended at the same time, destroying everything that blocked the road.


    Soon, only a ninth-level elemental energy core located in the center of the divine realm was left.


    The one who blocked the road was a huge mountain giant of the demigod level.


    The ninth-level elemental energy core is embedded in the giant.


    The White Tiger Talisman hung above the head of the Qinglong, and ten times the combat power was immediately increased.


    With a spurt of thunder, the body of the mountain giant suddenly exploded and rocks flew everywhere.


    The giants in the mountains roared and slapped their huge palms, causing a surging gust of wind.


    The Qinglong flexibly avoided, but was still swept by the strong wind.


    "Ding! Qinglong was slightly injured."


    The system prompt sounds.


    Seeing the prompt sound, Xu Chuan couldn''t help frowning.


    After all, the demigod species is still a demigod species. Even a ninth-level blue dragon with ten times its combat power may be injured.


    Thinking of this, Xu Chuan summoned the White Tiger.


    A tiger roar came out, and Qinglong''s combat power suddenly increased by a hundred times.


    Now, this demigod species is no longer a match for Qinglong, and soon turned into powder in the constant thunder of disaster.


    "Ding! Congratulations to the master for obtaining an earth element energy core!"


    The mountain giant collapsed and destroyed, and the earth-yellow elemental energy core flew out.


    "It''s actually earth element..."


    Seeing this elemental energy core that emits a icy yellow color, Xu Chuan shook his head helplessly.


    After all, I still couldn''t find the fire element energy core I needed.


    I can only wait for the next opportunity to continue searching.


    Xu Chuan put this earth element energy core into the system backpack, and then began to let the prehistoric divine realm swallow this ninth-level plane.


    However, at this moment, the mutation broke out.
