The giant tree man took heavy steps, and every step of the step, a mechanical warrior was stomped and scrapped.

However, they had no intention of retreating at all, and they still had the obligation to counter the impact of the attack...the impact! It was heroic like a moth that was blowing into fire.

The gap in strength and the restraint of the troops determine that this battle will eventually end with the failure of the mechanic warriors.

Tie Tower No. 4 and Tie Tower No. 5 joined forces to kill several giant tree men who were more than 100 meters tall, and withdrew from the battlefield under the order of Wang Jian.

Mechanical life is all the gods and people of the empire, and their status is noble, so they naturally cannot be sacrificed easily.

In addition to the main base No. 75, which was the mine to collect minerals every second, all other sub-bases were evacuated.

boom!

When a giant tree man stepped on a level 7-level velocity mechanical insect with one kick, there was finally no mechanical warrior on the battlefield.

Woo--

A tree leader made a low voice and his eyes were staring at the entrance of the mining point of the Bone Witch Tribe. Obviously, the movement there had attracted its attention.

"Humans--"

The long and old voice of the leader of the tree man heard, and then a group of giant tree man rushed towards the mining site in steps.

Dong! Dong! Dong! Dong!

The heavy footsteps were like a meteor falling to the ground, and each stroke shocked the ground in the valley.

Qiligagua Shandong has grown into Shuren Tribe, which lasts tens of thousands of miles until it reaches the Bone Witch Tribe before it becomes a low and undulating hill.

The Demon Valley is just a small dot, but after you really enter it, you will find it very large.

On the way from the Shuren Tribe Mining Site to the Guwu Tribe Mining Site, I don’t know how many giant Churen move collectively, just like a forest migrating, which is very spectacular.

“All mineral engineering vehicles retreat immediately!”

"Sub-base No. 75 is ready to fight!"

Zhang Feng had already made preparations, so he naturally issued an order immediately when he saw this.

The engineering vehicle full of Zijin Mine immediately entered the hatch of the No. 75 sub-base, teleported the wormhole through the space, and left.

"Hmph! No. 75 sub-base can't be lost in vain! Now, I want to test the effect of the base turret against giant tree people. The main gun is charged, aim at the front tree people, and attack!"

The sub-base was not invested in the battlefield just now, because the sub-base was moving very slowly, and once it was put into the battlefield, it would be very difficult to retreat. On the premise that the main battlefield failed, it would mean that investing in a sub-base would mean losing one.

However, there is no such concern now. Anyway, the No. 75 sub-base will enter the mine in a while and are fully prepared for the fall. Of course, we need to test the combat effect and provide combat data for future counterattacks.

"Yes, master! The main gun at the No. 75 sub-base starts to be charged! The second-level sub-base, the main gun charging time takes 3 seconds."

With the sound of the mechanical sound, a flip board at the top of the No. 75 sub-base was opened immediately, and a thick and short main gun was released, aiming at a giant tree man more than 100 meters tall in the front.

Choosing the target to be an ordinary giant tree man instead of a tree man leader is naturally to prevent them from joining forces to get the unknown green light again.

In a battle just now, the mechanic warriors have discovered this rule. If the attack is an ordinary giant tree man, it doesn't matter; but if the attack is an attacked tree man leader who is as high as 200 meters tall and makes them feel that their lives are threatened, they will unite and emit the green light that can absorb energy.

Therefore, in order to achieve results in the attack, the No. 75 sub-base decisively lowered its target and locked on ordinary giant treemen.

Zi —

boom!

The thick ji light column of the main gun hit the target accurately, and the trunks of the giant tree people hugged by more than a dozen people suddenly split into pieces, and wood chips flew everywhere.

The main gun of the sub-base showed its power for the first time, and destroyed a giant tree man with one shot. It seems that the attack effect of the main gun is still good - the premise is that the tree man does not use that green light for protection.

Seeing this, Zhang Feng was happy and continued to order: "Let's test the attack effect of the secondary cannon. Charge the secondary cannon and attack!"

"Yes, master! The secondary gun starts to charge! The secondary gun at the second-level sub-base is charged for 1 second."

Kick!

The flip board on the ball of the No. 75 sub-base slipped down, and five secondary gun muzzles were drawn, each locking an ordinary giant tree man.

"attack!"

Sizzy—

The muzzle of the secondary gun was also as thick as a bucket, and five huge beams of light shot out from the air.

Boom boom boom boom-

After a series of explosions, the large branches and wood chips on the five giant tree men were peeled off and flying all over the sky. However, they were shaking but did not fall down. They soon roared and continued to rush forward.

The experimental results show that the main gun of the second-level sub-base can instantly kill ordinary giant tree people; but the secondary gun can at most cause damage to the opponent but cannot be killed. The small gun does not need to be tested, so it is naturally even more impossible.

However, using the second-level base to kill the tree man is obviously not feasible.

First of all, the number of sub-bases is very small. There are only more than seventy in total. Moreover, each one is an "arsamir" that manufactures a large army of machinery. With them, the energy source is constantly transforming resources into a large army of machinery. If they lose, Zhang Feng would be very sad.

With the manufacturing speed of one sub-base per day at the main base, how long will it take to make up for this loss? What’s more important is, will Dragon Island and the human country give him this time?

I am reluctant to take risks! I am absolutely reluctant to take these valuable sub-bases to take risks.

Secondly, even if Zhang Feng can make up his mind and be willing to take out these sub-bases to fight. But once a large number of sub-bases are deployed, these treemen will definitely form a formation again and emit their perverted green light that can absorb energy. A sub-base launches attack on ordinary giant treemen, and the treemen leader can remain indifferent; if a large number of sub-bases are deployed, the treemen leaders feel threatened and will definitely not sit idly by.

Before finding a way to crack the abnormal green light, the dispatch of the sub-base will not achieve good results.

"Now there are enough purple gold. Perhaps, all equal-divided bases have been upgraded to level 3 and converted into spacecraft, you can try to let them attack."

The attack power of the third-level base is more than a little stronger than that of the second-level base. To put it bluntly, the second-level base is actually closer to the manufacturing factory. The main guns, secondary guns, and small guns are just to protect the safety of the factory.

The third-level base has achieved leapfrog changes. It can fly in the air and has a powerful maneuvering that meets the needs of the battlefield. Moreover, from its appearance, it can be seen that this is simply a combat spacecraft.

These words are long, but in fact they just flashed through Zhang Feng's mind.

At this time, the distance between the tree people was getting closer and closer.

Woo--

A giant tree man picked up a huge rock weighing tons from somewhere, and threw out his two arms like rattans.

call--

The huge rock roared towards the No. 75 sub-base with the sound of wind.

Without Zhang Feng's instructions, the No. 75 sub-base took the initiative to defend itself.

Drops—A small cannon's muzzle turned, and a white light flashed.

Bang!

The boulder has been blown to pieces.

The situation was urgent, and Zhang Feng did not dare to hesitate anymore and quickly ordered: "Sub-base No. 75, retreat! Enter the Zijin Mining Cave."

With the order, the No. 75 sub-base rumbled into the mine.

Woo--

More tree people roared and raised their stones and smashed them over.

Boom boom boom boom-

The 75th sub-base just entered the cave, and countless huge rocks roared near the entrance of the cave, with both earth and stone falling.

Woo--

Looking at the big black ball entering the hole, the giant tree man who finally arrived made a deep and long growl angrily.

Whoosh swish swish swish-

Several huge rattans flew out immediately and rolled towards the No. 75 sub-base.

However, it was too late. They only saw a back of the 75 Haomin Base, flashing in the chaos deep in the mine.

These giant tree men seemed to be very concerned about the chaos and did not dare to put the vines in casually. After wandering around the entrance of the mine, no traces of humans or mechanical puppets were found, and they began to slowly dissipate and returned to their own territory.

...

Let’s talk about the No. 75 sub-base. At the most critical moment, follow Zhang Feng’s order to turn around and enter the mine. Then open the energy cover to its maximum state and crash into the depths of the chaos without hesitation.

This is Zhang Feng’s plan.

Anyway, it is going to be sacrificed. Instead of letting the giant tree man destroy it, it is better to go to chaos to get into luck.

The mystery deep in the chaos of the Zijin Mining Cave, even after the level 7-level velocity mechanical insect enters, it cannot even send any message back.

However, when the energy cover is opened with all the energy cover, the defense power of the second-level sub-base is much greater than that of the seventh-level rapid mechanical worm. More importantly, there are spatial wormholes between the bases that can be connected to each other.

Zhang Feng specially arranged three level 7-level velocity mechanical worms to stay in the No. 75 sub-base. As soon as they enter the chaos, they will be teleported back through the space wormhole. In this way, even if the No. 75 sub-base is damaged, some information from the Chaos can be obtained.

Zhang Feng once suspected that perhaps this chaos is like a teleportation channel, and those rapid mechanical insects and mechanical prospecting ants are teleported to an unknown space.

If the guess is true, the second-level sub-base will be teleported away and there is nothing to worry about. As long as the distance is not far away, the mechanical army can teleport back and forth through the base space wormhole at any time. In this way, it will be equivalent to opening up another world for the development of the mechanical army.

Maybe that's another world?

Haha... Isn't that equivalent to traveling through time again? And it's so cool to be able to connect these two traveling worlds.

Zhang Feng was yy-looking, looking forward to it.

Boom-

The No. 75 sub-base directly drove into chaos.

As expected, through Chaos, the connection between the No. 75 sub-base and the main base was immediately broken.

The next moment, a huh.

A level 7-level velocity mechanical worm emerged from the wormhole of the No. 74 sub-base. For safety reasons, Zhang Feng naturally could not allow the velocity mechanical worm hiding in the No. 75 sub-base to be directly transmitted to the main base.

Zhang Feng was delighted.

However, there was no movement next time. In other words, only one of the three level 7-level velocity mechanical insects he arranged escaped; the remaining two, together with the No. 75 sub-base, were all gone.
Chapter completed!
