But the last time I explored the old city and drilled into the ground, Zhang Ping "sees" many thick metal tentacles and transportation pipelines, like tree roots, plunging into the depths of the earth.

At that time, Zhang Ping dived to more than 500 meters and did not see the end of these metal tentacles.

It is precisely this that Zhang Ping was 100% sure that the interior of the old city was very dangerous. What everyone saw on the ground was just the tip of the iceberg.

However, for Zhang Ping, when he got underground, he was his home court, which was carefully considered by Zhang Ping.

Of course, there are still dangers.

After moving forward horizontally for a moment, Zhang Ping "saw" many metal tentacles.

However, a small number of metal tentacles reaching this depth are ultimately small. Moreover, the movement speed of metal tentacles underneath is very slow and cannot catch up with Zhang Ping's movement speed.

Go forward, go forward, go forward.

Suddenly, a large number of metal tentacles appeared in front of them, like a network, blocking the way.

"Don't panic!"

Zhang Ping was holding two "hearts" in his mouth at this time, and they were both alive and had their own consciousness.

"It's time for you to exert your strength. I will provide you with the source of power!"

The power of the Resurrection Heart is activated, and the metal mesh in front is decaying. There are not many metal mesh underground, and there is no need to corrode much space. A half meter of diameter is enough.

If you look from the side at this time, you can see that a tiny metal dragon sprays out a certain source of force, and the metal roots in front of them decay; and then the metal dragon moves forward unimpededly.

But this way of progress requires a lot of source power.

Zhang Ping is still not panic!

At this time, Zhang Ping's source power reserve exceeded 500 million!

Burn hard.

An hour passed, tens of millions of source power were burned, and there was a sudden empty space in front of me, and no trace of metal tentacles could be found.

"I've escaped!" Zhang Ping burst into great joy in his heart.

Now look at the system interface:

[Discover the second generation's heart of resurrection and the second generation's heart of fusion, with a total value of 2 million contributions, and can be sold. Whether it is for sale.]

"Not for sale!" Zhang Ping closed the system interface.

"You cannot be a person without trust. Since I agree, I will try my best to do it unless I really can't."

Zhang Ping did not immediately get out of the ground, but walked underground for more than half an hour, and confirmed that there was no danger before finally moving upwards and approaching the ground.

When approaching the ground, it did not appear immediately. Instead, it used electromagnetic wave control capabilities to scan the surroundings to feel the vibration of the surrounding earth.

It was confirmed that it was safe, but Zhang Ping had not yet crawled out, but changed several places. After confirming that it was 100% safe, he finally crawled out of the ground.

This is a desolate hill. Zhang Ping is very familiar with this place. It is the place where he took the last look at the world before he changed his job.

It is more than ten kilometers away from the mother nest and more than three kilometers away from Hushan Town.

The fish belly appeared in the east, and the world was dark. There was a flash of fire in the direction of the mother nest, and there were rumbling explosions and fighting sounds.

Zhang Ping spit out his heart, turned into a metal body, and quietly looked at the "twin hearts", "I have brought you out and fulfilled what I promised. Where are you?"

I only saw the changes in my hearts and turned into two "light men", both of which were only half a meter high, which was a bit illusory, but it was human-shaped, no longer the strange shape I saw before.

However, the core of the "they" can be seen, one is in the shape of a water droplet, and the other is a spherical surface with threaded coils.

The water drop (Resurrection Heart) spoke first, and it turned out to be human language, "You didn't swallow us?"

"I, Zhang Ping, dare not say that I can do what I promised, but I will do my best."

The two hearts looked at each other, and the Resurrection Heart spoke: "Please prepare two source species, level 0 is enough, and stronger ones are better."

Is it an ordinary source species? It's very simple.

Zhang Ping's ability to control electromagnetic waves flashed, and soon he saw the familiar thing - Wolverine! It was still a group of 5.

"Wait for me a while."

The first time I saw Wolverine was before changing jobs, and it was also here; as a result, Wolverine was shot at the head by Chen Ying's changing sniper rifle as soon as she appeared.

Seeing such an "old friend" again, Zhang Ping felt that he should come forward and say hello.

The figure flashed before Wolverine.

"Roar..." The five-headed Wolverine roared and surrounded Zhang Ping.

Zhang Ping's hands changed, an orange light flashed, and a two-meter-long tungsten steel knife appeared.

"Roar!" A Wolverine rushed over.

A sword light flashed, and a wolf's head flew up.

Before the previous wolf head could land, the second wolf head flew up, followed by the third wolf head.

The first wolfish body finally fell to the ground.

The remaining two wolverines whined, ran away with their tails.

Zhang Ping stood still, the tungsten steel sword in his hand disappeared, and a strangely shaped, super-large-caliber air gun appeared.

The level 2 evolver is stronger and can easily drive the airsoft. In just three seconds, the airsoft is ready.

"puff!"

With a light sound, the head of a running wolf blew up.

Zhang Ping increased the pressure again without any hurry or slowness. After four seconds, all five Wolverines were destroyed.

Looking at the "air gun" in his hand, Zhang Ping smiled with satisfaction.

At level 1, the air gun is powerful but slow, and it fires 5 to 6 times a minute, which is a bit slow for the evolutionary speed.

Now it is increased to 3 seconds, and the speed is impressive if it is launched about 20 times a minute.

Especially after swallowing the "nano liquid gold", it is also beneficial to the air gun. In addition to lubrication, the more important thing is "sealing".

Lubricating oil usually has a certain sealing effect. Today's nano-liquid gold has better effect.

Zhang Ping could clearly sense that the power of the air gun was also significantly improved.

Picking up the 5 source seeds, Zhang Ping swayed back to the hillside - in fact, Zhang Ping has always used electromagnetic wave control capabilities to supervise the twin hearts.

If you attach more importance to Cigna, it does not mean that others will do it, and other "monsters" will do it.

Fortunately, my heart remained still.

Put the five source seeds in front of the two hearts, and the two hearts take action.

Shuangxin didn't talk nonsense, and just picked up a source seed and swallowed it. They also reached their limit.

I picked up another source seed and became busy. I could clearly see that a tiny heart of fusion and a tiny heart of resurrection were taking shape.

Zhang Ping looked at it silently, but was extremely excited.

Replica!

What if you can replicate the heart of fusion in the future, and the heart of resurrection? Especially the heart of resurrection!

When ordinary people use the heart of resurrection to change jobs, the success rate is 100%. What is this? This is the code of wealth in the end of the world, the code of immortality.

In about one minute, the two walnut-sized hearts and the resurrection heart were placed in front of Zhang Ping.

The Resurrection Heart spoke, "Hello Zhang Ping, this is the blueprint of the fusion heart, the resurrection heart. It is the blueprint. With the blueprint, you can create the resurrection heart and the fusion heart yourself."

Blueprint for both hearts!

Even after so much, Zhang Ping was still so excited that he couldn't help himself, and his hands were trembling.

The moment when the double hearts get it, the system pops up:

[Dingdong, discover the second generation's resurrection heart, the blueprint of the heart of fusion, perfect. Value...]

"System, I won't sell this blueprint!" Zhang Ping refused directly without waiting for the system to remind him.

Now Zhang Ping has figured out the situation of the system: this is a terminal. Although he only owns it on the earth, he has a lot of it in the starry sky.

All the technologies you sell in the system can be bought by other "players". For example, the various things you bought before.

Even the various equipment customized by oneself are mostly ordered by the system to other "high-end players".

So, since you have the blueprint of resurrection and fusion heart and have mastered the technology, why do you still have to sell technology? Selling products is the right thing to do!

However, compared with the system's problems, Zhang Ping still has many questions about the twin hearts. While the "living twin hearts" are still there, Zhang Ping seized the time to ask.

"By the way, what do you guys call me?"

The Resurrection Heart spoke: "My name is 'Six Arms', and his name is 'Iron Arms'."

"...a very unique name." Zhang Ping gave an evaluation against his will.

"Thank you." Shuangxin spoke at the same time.

"Can I ask a question?"

The hearts looked at each other, and the heart of the resurrection spoke, "Yes. But our answer may not necessarily satisfy you. Because there are many things that we don't know."
