4.6 Billion Year Symphony of Evolution

'Boom Bang Bang!'

The roar of the cannon is echoing continuously.

Countless ammunition fired frantically, they passed through the air, penetrating the enemy troops running one by one.

Here is ... outside the entrance of the institute, in the rocky cave, a large number of three-legged columns are running wild on the ground.

They have only one goal, and that is the gate of the institute.

However, the gate of the institute has been tightly closed, and a large number of hanging cannons were stretched on the top of the cave, shooting at all three legs in the cave.

The three-legged column fell three times in succession, but they showed no signs of stopping at all, but kept running towards the gate.

"They are so many ..." In the main control room inside the research institute, the mechanical dust crocodile called up an external monitoring screen, and from the screen, a large number of three-legged columns were charging towards the gate.

The only way to attack these three-legged posts is when they walk close enough to the gate to emit a seemingly high temperature light from the light spot on the head, burning a scorched crack on the gate.

However, their attacks will not last long, they will be shot by the upper cannons, and fall to the ground one after another.

"There were so many cannons in the cave outside the original research institute ..." Scholars mainly focused on the cannons on the top of the cave. The cannons seemed to be hidden in the cracks in the rocks. They didn't even notice when they came.

Now, mechanical dust crocodiles stretch them out for attack.

"Ammunition is being consumed violently." The mini dust crocodile on the side said: "According to the current consumption speed, as long as the shooting continues for 60 seconds, it will be consumed."

The scholar asked: "Is there no spare ammunition?"

"In search ... there are no spare ammunition." Mini Dust Crocodile said: "The spare ammunition depot is completely vacant."

"How can it be empty ..."

The scholar's words hadn't been finished yet, there was a "boom" in the picture. I saw a big hole in the closed door, and a large number of three-legged columns climbed into the first hall of the institute from the big hole. in.

"They all come in!" The mechanical dust crocodile quickly opened the cannon in the hall, but the cannon in the hall just rotated there without shooting any ammunition.

"In the hall, the ammunition reserve is 0." The mini dust crocodile said: "It is recommended to replenish ammunition. If the situation is critical and cannot be refilled, it is recommended to activate the self-detonation system."

"Self-detonation system?" The mechanical dust crocodile asked: "What is that?"

"You have obtained all permissions and can view all weapons and equipment information." Mini Dust Crocodile said: "If you want to understand the self-detonation system, please refer to section 371, paragraph 6 on the composition of weapons, which has a detailed description of how it should be Safely use the self-explosive system ... "

"Ah! They have come here!" Dust Crocodile suddenly exclaimed, and saw a large number of three-legged posts lying on the entrance door leading to the main control room, and a big hole was melted in the door .

The sound of the cannons sounded again, because the road from the hall to the main control room was also defended by cannons, and these cannons still had ammunition.

But the mechanical dust crocodile looked very anxious, because the three-legged columns were as crazy as they were outside at the time, desperately rushing towards the main control room.

Although the cannon can block them, the ammunition will run out, and I do n’t know why. The cannon in this research ... the amount of ammunition seems to be a bit problem, not to mention the spare ammunition, even the own ammunition is not satisfied, like The cannon in the hall is directly devoid of ammunition.

As for the ammunition in this passage, the mini dust crocodile also said: "Continue to shoot for 100 seconds, the ammunition will be consumed."

"What should we do?"

The scholar looked at the dust crocodile anxiously, and he was also anxious himself.

Because these three-legged columns are not as weak as carrion bones, they still have many ways of attacking, and the number is still so many ... The starting state may not be able to resist them.

In this case……

"In this case, we can only escape from here." This is the voice of the beginning, which also made scholars and mechanical dust crocodiles look at it.

"How to escape?" The mechanical dust crocodile said first: "There is no other way!"

"There is a way." Shijing looked at the cultivating creature bound to the side and said, "It came in through that way."

"What are you talking about? I walked in from outside." The cultivator said.

"No, you used ... Congdu's passage." Shi Jing said: "In this research institute, there are also disguised Congdu mixed in, possibly pretending to be a researcher, and here he prepared himself a safety Access so that I can ... leave at any time. "

"You are using something you got from it, using its channel to come here, right." Shijing floated to the front of the cultivating creature and said, "Where is that channel?"

"What are you talking about? Even if I came like that, I won't tell you!" Said the creature, "and ..."

'boom--!'

Before its words fell, there was a burst of noise from the control room. The strong explosion made a hole in the gate, just like ... before, a large number of three-legged columns climbed in from the outside.

"Ah!" Cultivating creatures screamed immediately: "What kind of monster is this? What's going on!"

'Boom!'After a while, the three legs that climbed in were struck and hit the wall. At the beginning, the realm said to the practicing creature: "Do you want to tell us now?"

"I said! I said! I tell you how I came in. Hurry and take me out! I don't want to die yet!"

"..." It seems that before cultivating creatures, I didn't know that the danger was approaching, so I just refused to say it, but now it is very ... simply, scholars think this kind of creature is ... fun.

"It's there!" The cultivating creature expressed a position in the corner of the control room with his eyes: "Release me and let me go to that position, and I will take you away!"

But it has not been let go, a singular force lifted the practice creatures from the ground into the air, and then the beginning said to scholars and reporters Dust Crocodile: "Let ’s go."

"... Okay!" They didn't hesitate too much, and ran quickly to the corner where they practiced biological fingers before a new three-legged post climbed in.

'Bang--!'A burst of explosive noise, this place originally had a lot of mechanical structures, but after the explosion, it all shattered everywhere, and the mechanical dust crocodile suddenly said angrily to the beginning: "Are you blown up?"

"because this."

Under the broken mechanical parts, a strange thing is revealed ...
