As for the extension, I don't know what it is for the time being, but Tang Dong still has a little guess in his heart.

Of course, you have to wait for 100 points of evolution power to try it.

He is now poor, and he was there with the old man in the morning, the main purpose was to make some money, and Tang Dong did not go on a killing spree under the sea, for fear of scaring away the other fish.

So on the first trip to the sea, the power of evolution increased by 10 points.

Later, it took 11 points to recover some of the lost Force, but it has not fully recovered, but there are only 20 points of evolution power left.

It's good now, the money is gone, and the power of evolution is gone.

Still only extracting 1 point of evolutionary power, Tang Dong concentrated his consciousness on the [Secret Method] Jin Kun Devouring Light Diagram, and then, the three words that can be upgraded disappeared, and a progress bar appeared.

It's just that the whole progress bar is gray, not to mention the hair, not even the blue light of the size of the hair.

Is this system down?

Tang Dong was surprised, and extracted 1 point of evolution power and used it to upgrade the copper skin method, and as a result, a progress bar also appeared, but there was still a little faint blue light, about one in five hundred.

For some reason, Tang Dong had this data in his heart.

In other words, with 500 points of evolution power, you can upgrade the copper skin method, which is exactly half of what you need to upgrade the sandfish sea spirit.

Tang Dong extracted another 1 point of evolution power to upgrade the Golden Kun Devouring Light Map, and then another 1 point, 1 point......

It took a full 9 o'clock, and the progress bar was still completely gray, and it didn't move.

Tang Dong stopped trying, he felt that the system must not be broken, to blame, he could only blame himself for being too poor, and taking 9 points of evolution power to upgrade the Golden Kun Devouring Light Map might be like taking a piece of grass the size of a hair to feed a hungry fat cow, it would be like throwing a drop of water into the sea.

It's not enough to see.

Upgrading the Golden Kun Devouring Light Map requires a massive amount of evolutionary power!

This is normal, after all, as long as you are not blind, you can see that this is a top-level concept, and it is inevitable that it will be difficult to upgrade.

After carefully thinking about the content of the conversation with Lao Bai in the morning, Tang Dong thought about it, and did not immediately start refining the skin and flesh, even if he had just read the copper skin method and knew how to refine it, he did not do that.

Because quenching consumes the Force, which is like steelmaking, the body is steel, and the Force is fuel.

To replenish the Force, you have to use the power of evolution, Tang Dong is too poor now, and the power of evolution is only 10 points, so this method cannot be done.

Of course, you can replenish the Force without the power of evolution, for example, after Tang Dong passed a whole morning, the real value of the Source Sea in the system changed from 0.61 to 0.65 by itself.

This means that his body can also absorb the Qi of Heaven and Earth from the air on its own, replenishing less than 4% of the Force consumption in his body.

It took a whole morning, almost three hours, to replenish 4%, and at this rate, if the Force was exhausted, it would take more than three days to fully replenish it.

Of course, the true sea masters will not wait for replenishment like this, they will use their contemplation to speed up the absorption of the qi of heaven and earth in the outside world.

If you are rich, you will also use rough stones.

Tang Dong has no original stone, no power of evolution, but he has the idea of contemplation! It's still the kind that looks particularly high.

Moving his butt to the side of the bed, just under the sunlight that ran into the room, Tang Dong spread out the picture of the golden kun swallowing light in front of him, and according to the small words on the corner of the picture that seemed to be added by others, he wrapped his eyes in the force, and stared at the whole pattern tightly.

In an instant, this picture seemed to come to life, Tang Dong seemed to see a real golden giant kun, swimming upside from the bottomless ocean, vacating the water at a certain moment, slapping the earth-shattering waves, looking up to the sky and opening its big mouth, an unparalleled suction burst out.

Then, the sunlight disappeared, and the clear sky instantly turned into a starry night, and the stars appeared, and the great sun hanging in the sky became dim.

Only the golden giant kun seemed to have become the only one in the world, emitting ten thousand golden rays of light.

Tang Dong's eyes seemed to have watched this scene through layers of void across time.

At the same time, several golden silk threads also appeared out of thin air in the sky above the source sea in his body, twisting, wriggling and combining together, and finally, forming a four-like form.

Not like fish, not like kun.

But the moment the four dissimilarities appeared, the Force cyclone covering the source sea also changed, from a sky-blue mist to a blue mist with a hint of gold.

In Tang Dong's Source Sea, more than sixty percent of the area was covered by the Force Cyclone, and when the original Force was not consumed, it completely covered the Source Sea, and after he went to the sea to consume some, the Force Cyclone also contracted.

This Force Cyclone is a projection of the Force in his body, and its size also represents the surplus of Force in his body.

In an instant, Tang Dong's Force had an additional trait, light, high temperature, and the Force surged, Tang Dong really felt that his body temperature had become much higher, which had exceeded the scope of normal people, which was given by these qualities.

Not only that, when the golden four shapes over the source sea were formed, Tang Dong clearly felt that there was a suction force coming out of his body, absorbing some special particles from the air that was flowing from the pores of his body to the surrounding air.

It is the energy particle between heaven and earth, also known as the qi of heaven and earth, which can replenish the force consumption in the body of the sea rider.

The suction absorption in the body is many times faster than the body's self-absorption, and it may take him a day and a half to replenish all the consumption.

But now, Tang Dong feels that it may only take half a day to be enough, maybe less.

This is the effect of contemplation, and the so-called visualization is contemplation.

After looking at and thinking, looking at the things on the map, looking at their connotations, thinking, and observing their true meanings, then thinking about them in their minds and minds, outlining the things they are looking at with their mental power, and constructing them in the sky over the source sea.

To reach the pinnacle of contemplation, it is necessary not only to construct the form, but also to construct the god.

When this step is reached, it will be able to directly devour the qi of heaven and earth, just like the things on the visualization map, and even replenish all the consumption in an instant.

Tang Dong had only constructed a few twisted lines and combined them into a four-dimensional dislike that was nothing, which had already caused a qualitative change in the Force, and the speed of recovering the Force had also increased by more than three times, which showed the effect of contemplation!

Tang Dong's heart was agitated, and he didn't know what kind of scene it was when he completely sketched the real scene in the source sea of the golden kun swallowing light? What are the qualities that are given?

But that kind of road, now there is no end in sight, only a few twisted gold lines are outlined at the moment, and a four-like is constructed, and the mind is already extremely tired, and it is about to be unable to control its stability, if the real scene is constructed, at least tens of thousands of gold wires!

I don't know how long it will be, and this may need to use the derivation function of the system.

Without making any more new gold threads, Tang Dong closed his eyes and focused on stabilizing the four dissimilarities, correcting those distorted lines little by little.

As the four dissimilarities became more and more similar, Tang Dong's speed of absorbing the qi of heaven and earth was also slowly increasing, and the force surging in his body seemed to have become a lot stronger, which was a change in nature.

Perhaps, contemplation is also one of the core of the sea rider......
