More than an hour later, on a small hill five kilometers away from the suburbs of the old city, Zhang Ping turned into a metal body and looked back at the old city where the war was shining.

"Both hearts have left, what are they still fighting?" Zhang Ping was puzzled.

"Forget it, let's not worry about it for now, let's see what you gain this time!"

Let’s take a look at the system interface:

【LV2.1(0/30,000)

Contribution, 372,272 points;

Source: 33.9 million 1170 points;

Attributes: Heart of Silence, Heart of Fusion (First Generation Source Seed, Preliminary Fusion), Heart of Resurrection (First Generation Source Seed, Can Drop)

Lottery: 5 times;

Heart of the Machine: Single-cylinder engine, three-speed transmission powertrain.]

Looking at the system interface, Zhang Ping carefully summarized.

First of all, the source power consumption is getting bigger and bigger. The source power was as high as 38.4 million, but now there is only 33.9 million left, consuming more than 500,000 source power.

The source power consumed in fierce battles is far beyond the theoretical limit.

Especially when the metal dragon digging holes underground, the source power is consumed like flowing water, and it is completely like a 'upper-top' attitude.

This needs attention.

Secondly, this time the exploration was almost crazy on the verge of death, and now I think about it and feel cold sweat.

There are also various other problems. After Zhang Ping carefully considered the matter, he kept the lessons learned in his heart.

Then, look at the "heart of integration".

There are three choices to absorb the heart of fusion and the heart of resurrection:

1. Consumption of 5 million source power, 24 hours, fully controlled, and cannot be dropped;

2. Consumption of 1 million source power, 5 hours, initial control, and cannot be dropped;

3. Consumption of 100,000 source power, 30 minutes, can be hidden and carried, and can be released.

In the Heart of Resurrection, Zhang Ping chose the third option.

As for the heart of integration, Zhang Ping chose the second one, because the source power was insufficient before.

Now, absorb it completely!

Continuing to consume 4 million source power and offset 19 hours with 1,140 contributions, Zhang Ping completely absorbed the heart of fusion.

System interface changes:

【LV2.1(0/30,000)

Contribution, 371,132 points;

Source: 29.9 million 1170 points;

Attributes: Silent Heart, Resurrection Heart (can be dropped);

…

The second source species: Fusion Heart (first generation source species, completely controlled, not activated)]

A new "second source" project has been added to the system!

"The next five lottery draws!"

Zhang Ping couldn't help rubbing his hands, and the metal palm rubbed a harsh sound, but Zhang Ping felt it was very pleasant.

Free lottery twice, lottery results:

[Get a consolation prize: 1,000 source power.]

【Get a 'Feeding Notes on Metal Life', a rare item.】

"Rare items!" Zhang Ping's eyes lit up and he instantly absorbed the relevant content.

After understanding the content, Zhang Ping said, "It turns out to be a rare and useless person!

But it's not bad for me, it can assist the evolution of the metal dragon."

There are three paid lottery draws, namely, the contribution point is 100,000, the source power is 100,000, and the source power is 1 million.

Zhang Ping looked for a while and suddenly asked: "System, according to the rules, the contribution points exceed 100,000, so there should be a lottery, right?"

[Dingdong, you will get the gluten with a contribution of 100,000 yuan at level 2! This lottery is arranged at level 3.]

Zhang Ping nodded. It would be nice to have a living system.

The system started to draw three consecutive times, and the system deducted 10,000 contributions and 1.1 million source power.

[Get the entire article of "Junior Human Body Motion Minery", including bare-hand combat, cold weapon combat, and primary metal body combat routines (martial arts).

Actual value: 50,000 source power, 1,500 contributions, 2-level technology.]

[Get 2 kg of 'nano liquid gold', which can be used as a lubricant for the heart of the machine and metal body, reducing the heavy loss of force transmitted.

Actual value: 10,000 source power per kilogram, 1,000 contribution, 5-level technology.]

[Get the 'tungsten steel knives', powder alloy steel technology.

Actual value: 50,000 source power, 2,000 contributions, 4th level peak technology.]

The result of three consecutive draws was really good.

"Junior human motor mechanics", Zhang Ping had only obtained the part of "bare-hand combat" before, and benefited a lot.

Later, these technologies were extended to cold weapons, and the effect was good, but it was a little worse after all. Now, not only did it complete, but it also obtained the "Martial Arts Routine for Metal Body"!

And "nano liquid gold" is precious, and the level 5 technology. Zhang Ping is now at level 2, and if you want to buy it directly, it will cost eight times the price.

The tungsten steel war knife made Zhang Ping even more happy. This is a lengthened and widened saber shape:

It has a length of 1.2 meters and a width of up to ten centimeters, just in line with Zhang Ping's body;

There are two 1 meter extension handles, which can be used as an iron rod alone; after splicing, it is exactly 3 meters.

Gently waved the long knife, and the heavy tungsten steel big knife whimpered.

With one sword, he slashed the wreckage of a tank next to him, and the heavy tank armor broke through half of it, like a rotten wood.

Take the big knife in front of you and observe carefully, and the system provides basic information:

Powder alloy steel technology eliminates the brittleness of tungsten steel, strengthens toughness, and increases hardness to the limit - infinitely close to diamond hardness.

After a series of crazy battles, Zhang Ping attached great importance to the battle of cold weapons.

With the rapid rise of evolutionists, the power of ordinary arms began to be somewhat insufficient. For example, Wu Jihai's main body's attack, shells, machine cannons, etc. this time, it is difficult to lock in long-range targets.

Fighting between evolvers, melee combat is becoming more and more important.

After being excited for a while, Zhang Ping suddenly discovered a small problem, "System, I bought it myself, and it seems that I can only buy things from the Level 2 technology tree.

Why do you get higher-technical skills in the lottery, and the previous sniper rifle guide?

It seems that the technology and information are not available in the technology tree?"

[Dingdong, gray transaction. Only lottery is within the rules.

In addition, the technology tree only provides basic information and technology.]

"So that's it. Does even the system like wealth?"

[Dingdong, the system and the host are one. If the host is strong, the system will be powerful.]

Zhang Ping nodded, and 2 kilograms of nano liquid gold appeared in his hand, which was placed in an iron can. The surface of the iron can was engraved with instructions.

The nano liquid gold is like flowing golden milk. I dipped it a little with my metal fingers and gently rubbed my fingers, and I could hardly feel the friction.

"Good thing!" Lubricant is the blood of the machine; and in many cases, lubricant also plays a part of the sealing role.

Carefully "drink" liquid gold, and the fluid-like liquid gold quickly penetrates into every key part of the metal body.

After drinking 1 kg, the whole body is fully lubricated; you can feel that the power transmission of the whole body is smoother.

The system gives a tip: the power transmission efficiency of each stage has been increased from 98% to 99%!

Looking at the remaining kilogram, Zhang carefully put it in his toolbox and saved it for later use.

Although lubricating oil is good, it also has a lifespan.

"Next, it's time to go home!"
Chapter completed!
