Evolution Frenzy

   "Huh? When will the evolutionary tree come back? Xiaoli, isn't this your body?" Duan Fei was curious.

  In the evolutionary system, there was originally a sapling of the evolutionary sacred tree, which was the center of the entire evolutionary system. In the remains of the ancient gods in Qinchuan, the evolutionary tree absorbed the mysterious red fruit before it turned into a little loli!

  At this time, the evolutionary tree reappears in the evolutionary system. Moreover, it seems to be a lot stronger than before, and he is already alone in his arms!

   "Huh, you will know by looking carefully!" Evolution tree Xiaoli did not directly answer Duan Fei's question, but coldly hummed, turned around and entered the evolution tree entrance, and disappeared.

   "Huh? Xiaoli, how did you get in? Wait for me—" Duan Fei saw that Xiaoli entered the evolutionary tree and disappeared, so he quickly followed in.

   "Wow, good space!"

As soon as Duan Fei entered the evolutionary tree, he was surprised to find that there was a huge space inside!

  It looks like a hole all around, and there is cyan light gleaming everywhere, and on the surrounding rock walls, there are all kinds of green vines. Their green leaves are very luxuriant, and the green is dripping!

  Just as Duan Fei was curious, a bright light suddenly appeared on the wall in the center of the cave, and then a three-dimensional screen appeared!

  "Welcome to the evolutionary tree ecosystem! I am the intelligent life of the evolutionary system, Xiaoli, the evolutionary tree!"

  The evolution tree Xiaoli's figure appeared on the screen. She looked at Duan Fei, but her voice did not contain the slightest emotion.

   "Xiao Li, why is there such a large space here? You never told me that there is an ecosystem in the evolutionary tree?" Duan Fei said in surprise.

"Voice confirmation! Allowed to enter! Please select a trial level! Since your current level is only the general strength of the yellow rank, the trial levels you can choose are only level one and two, and higher level trials will be at your level two. Open after clearing the level! Please choose!" Evolution Tree Xiaoli is like a broadcaster, her voice is flat but firm, without the slightest personal feelings.

   "Xiao Li just said to take me to find a place for the trial, could it be this?" Duan Fei understood.

  The evolutionary tree Xiaoli is the incarnation of the evolutionary tree, and now it has returned to itself. And it turned into the artificial intelligence in the evolutionary tree, but this is artificial intelligence and does not contain Xiaoli's feelings!

  In the evolutionary tree, there is an ecosystem hidden!

"It is estimated that it was specially used for the trial after strengthening the skills! Moreover, the opening of the ecosystem in the evolution system should have certain conditions, otherwise it will not be open to me until today! It should be triggered by the previous upgrade of the yellow level skills. Certain agencies, only then opened their authority!" Duan Fei seemed to understand.

  "Anyway, try it first! The evolutionary tree will definitely not harm me!" Duan Fei took a step forward.

   "Little Li, open the first level trial!"

  "Beep~The door to the first level trial is open, please go to the ecosystem trial!"

   A sound of electronic access control sounded, and a strong white light appeared on the other side of the cave.

   "It turned out to be a door! Is it connected to the outside?" Duan Fei was surprised that a door appeared in the deepest part of the cave, and strong sunlight shot in from the door.

   "Very good, go and see!" Duan Fei walked towards the door.

   "What a fresh breath!" As soon as he entered the door, a scent of air came oncoming, Duan Fei took a breath of fresh air, and his whole body was comfortable.

  Since the end of the world, zombies and viruses have been rampant, wars have been frequent, and environmental pollution has been very serious. Duan Fei hasn’t breathed such fresh air for a long time!

  "Beep!" The sound of the electronic access control sounded again, and the electronic door behind Duan Fei closed automatically.

   "Huh? Where is it?" Duan Fei has no time to care about the electronic door behind him, because what is displayed in front of him is a huge ecosystem!

  Old old trees, connected pine forests, and mountains and plains of flowers and weeds! The ground is green, and the mountains are blue!

   "It's so beautiful! I haven't seen such a beautiful scenery for a long time!" Duan Fei was surprised.

  You must know that in reality outside, it is the hinterland of Qinchuan. At this time, it is late autumn, and the mountains and plains are full of dry yellow grass. Where can there be such a spring-like scenery!

  What's more, zombies are rampant, wars and disputes, if China has long been compared today, there are corpses and deserted people everywhere, even in spring, it is hard to find a quiet land!

  And here, it is obviously an ecosystem independent of the outside world!

   "But, there seems to be something wrong!" Duan Fei walked and observed carefully, and gradually discovered the problem here.

  Although the mountains are full of plants, flowers and grasses of various colors cover the entire mountain, but no animal is seen!

  Butterfly, bee, tit, forest bird...none! Not even an ant can be seen!

   "Illusive! This is Illusive! That is..." Duan Fei suddenly realized that although the ecosystem in front of him was detailed and realistic, it should be illusory! Otherwise, it is impossible for a huge ecosystem to be without animals!

  Just as Duan Fei woke up, a behemoth rushed towards him!

   "Not good! That's... how could it be?" Duan Fei was shocked when the monster rushed over, why he couldn't believe his eyes!

  The monster that rushed over was exactly the same as the ridiculous lizard monster encountered in the battle of the South Gate of the Yanhuang Great City!

  The monster was clearly killed by his own special skill "primary explosion", why does it still appear here?

Duan Fei is puzzled! But then, thinking of something, he couldn't help but smile.

  The monster rushed over in the blink of an eye, Duan Fei stretched out his right hand, and the force weapon black spear appeared in his hand!

  "This should be the trial that Xiaoli said! Well, a lizard monster with a thief smile, then let me abuse you again!"

  At this time, Duan Fei's strength level was raised to Yellow Tier 4, and his agility to Yellow Tier 3, which was far beyond the strength of the Nanmen battle, but Duan Fei did not know how much it improved!

  So, after the skills are improved, you still have to rely on actual combat to test the degree of improvement!

   "Roar~" The lizard monster opened its mouth and bit towards Duan Fei's body.

   "Yeah~ I'll let you bite!" Duan Fei did not dodge, the spear in his hand pierced the upper jaw of the lizard monster in one fell swoop!

   "Pump!" With a sound, the force spear directly penetrated the upper jaw of the lizard monster!

   Suddenly a burst of black blood spurted down!

   "Okay! Actually, the power has increased so much all of a sudden! As expected of Huang Tier 4!" Duan Fei secretly said.

  At the moment of the attack, Duan Fei could clearly feel the resistance of the force steel in this lizard monster!

  In other words, this lizard monster is no different from the monster he encountered on the southern battlefield in terms of physical strength, ability, and even physical structure!
