How big the different space is, although Gao Feng has been here twice, he can't say clearly.

Preliminary estimates suggest that this alien space is large enough to accommodate the solar system.

Such a space is large enough for any individual life. Although Montenegro is the king, in the face of such a huge space, it is impossible to search every corner in great detail.

What's more, Gao Feng himself has various hidden secret methods. In this space, Gao Feng is like a swimming fish entering the sea.

With Montenegro itself, it is absolutely impossible to search for Gao Feng.

However, Montenegro could not find Gao Feng, but he could sense the location of the Dark Furnace.

When Black Mountain was refining the Dark Furnace, he didn't dare to leave the King Armor Ship for a moment. Only with the powerful Demon Spirit Hedron can Black Mountain extract the energy needed to meet the needs of the Dark Forge Furnace.

And, as the Dark Forge grows, so does the need for energy.

Not to mention Gao Feng, a golden powerhouse, even a king-level powerhouse can hardly meet the needs of the dark furnace.

Montenegro has such concerns, and has never dared to let go of the dark furnace.

Gao Feng stuffed the long river into the Dark Furnace, and the king-level Origin Core also activated the Dark Furnace.

Although Gao Feng temporarily sealed the Dark Forge for the time being, the Dark Forge needed to draw energy frantically every once in a while.

By the time the Dark Forge is running again, Gao Feng will be finished!

It was with such certainty that Montenegro dared to brazenly destroy the entrance to the space. With absolute confidence, Montenegro headed into the depths of space.

This space is rich in resources and has many powerful creatures. Montenegro decided to take advantage of his free time to hunt some powerful creatures as a reserve of energy.

At the same time, Gao Feng, who was hiding deep underground, was heading deep underground along the naturally formed cracks.

The last time he came, Gao Feng took away more than a thousand golden light stones. According to his estimates, there is a vein of golden light stone deep underground.

This time he has been cornered, and only by finding the large veins of the Golden Light Stone can he satisfy the needs of the Dark Furnace.

Gao Feng believed that as long as he met the needs of the Dark Furnace, he would be able to refine the Dark Furnace and combine it with the Battle Dragon Armor.

With the Dark Forge as the core of the source power, it is enough to push the Battle Dragon Armor to the king-level level.

Although there are a lot of technical details that need to be solved, Gao Feng has confidence in himself. His dimensional space also contains enough materials.

At that time, Montenegro was just a dish!

Like Montenegro, Gao Feng has great confidence in his victory.

The environment underneath is very complex, with underground rivers, red-hot magma, hard rock layers, and so on. There are also all kinds of bizarre and dangerous creatures.

For Gao Feng, the complex environment and dangerous creatures are just some embellishments on the boring journey.

Armed with the Battle Dragon Armor, the strength below the king level was no longer a threat to Gao Feng.

When encountering an impassable place, Gao Feng used the secret method of dissolving the void, and easily passed through the stratum like a phantom.

Along the direction of the ore vein, all the way to the bottom, walked tens of thousands of kilometers, and did not find a large gold light stone vein.

Some scattered golden stones have been found, and there are more than 3,000 fragments.

If you take it out, it will also be a great fortune. But according to Gao Feng's estimate, these golden light stones are far from enough.

The situation in the depths of the underground is also more complicated than Gao Feng imagined, with a distance of tens of thousands of kilometers, and the earth has already worn a few round-trips. But the underground world here seems to have no end.

Gao Feng was not too anxious. The Dark Forge had devoured so much energy and placed it in dimensional space, and he had been in it for at least two months.

As for the situation in the Andromeda Galaxy, Gao Feng couldn't do anything about it! However, the most powerful king of the trolls was dragged here by him, which also created the best conditions for the empire to fight back.

Gao Feng still arranged a move at Rod's place, and when Rod's return, he would find that he had an extra demon spirit crystal in his head.

This kind of good thing, the Titan Empire will never miss it.

Of course, Gao Feng also informed Ye Jingshen about the Demon Spirit Crystal. Otherwise, he wouldn't have obediently run over to help.

Once humans discover that trolls are of great value, trolls are not far from extinction.

On the fourth day of his journey through the Underground World, Gao Feng made a breakthrough.

A long underground river flows, and the water of the underground river, without any light source, shimmers with clear golden light.

Sandwiched between the strata, this underground river is sealed inside a huge pipe, and the outside is not at all perceptible.

As soon as he entered the underground river, Gao Feng felt the coldness that penetrated his bones. The temperature of the river is close to absolute zero, and the water is particularly viscous and heavy, like molten iron.

In the depths of the river, countless golden stones were spread on the bottom of the water, and the radiating golden light stained the river water, forming a thousand-meter-long golden river.

Gao Feng couldn't help but be overjoyed, the golden light stone veins here were even bigger than he had imagined. It is sealed underwater by a special river water, and the pure energy of the golden light stone is completely sealed.

After taking a look at his surroundings, Gao Feng began to dive, preparing to dig up the Golden Light Stone.

In the golden wave shining, a golden light and shadow suddenly attacked Gao Feng. In the rolling waves of golden water, the golden light and shadow had swallowed Gao Feng into his belly.

It turned out that the golden light shadow was a big fish tens of meters long, transparent as crystal, able to transmit any light. Floating quietly in the golden waves, there is nothing unusual to be seen.

The river water here suppressed the divine induction, and Gao Feng didn't find this giant fish just now.

The crystal fish has been alive in the river for an unknown amount of time, and it usually feeds on golden light stones. Occasionally, it will devour other creatures that stumble into.

For a long time, it also gave the giant fish a strong force. However, its species also limits its achievements. In this simple world without any pressure, its thinking is just as simple, and it is worse than a three-year-old human being and a toddler.

Therefore, the giant fish swallowed Gao Feng without thinking.

This instinct-only creature, although its strength has reached the peak of gold, does not pose any threat to Gao Feng.

With a single urge of the two swords, the sword light easily crushed the nerves in the giant fish's head, ending its life.

I don't know what the effect of such a big fish is, and Gao Feng doesn't have time to study it, so he casually enters the dimensional space. The most important thing right now is to dig for gold.

The pressure in the depths of the river was huge, but it couldn't stop Gao Feng. Although the king-level sword weapon is a bit wasteful as a digging tool, it is very efficient.

When the two swords went down, a large piece of golden light stone connected to one piece was excavated.

Three hours later, Gao Feng emerged from the depths of the water. The ultra-efficient excavation allowed him to dig up more than 300,000 golden stones in a short period of time.

Less than one percent of the kilometer-long veins of gold light stone have been excavated. Such a huge reserve is also beyond any gold vein that Gao Feng knows.

300,000 golden stones, it is an exaggeration to say that it is a rich country. It's also enough to compare with some super-large interstellar companies.

Such a huge harvest made Gao Feng can't help but be happy. Wealth doesn't mean much to him, but these golden light stones can help Gao Feng solve big problems.

Gao Feng glanced at this vein with some pity, and the remaining golden light stones could only be placed here temporarily.

There are still many places in the dimensional space, but there is a dark furnace inside, and there are too many golden light stones, which can easily stimulate the energy reaction of the dark furnace.

No matter how you calculate it, 300,000 golden light stones are enough. When the problem of the Dark Forge is solved, it is not too late to come back and get these light stones.

Gao Feng didn't dare to stay here longer, there was not much time left, he had to hurry.

It takes a long time to refine the Dark Forge Furnace. Gao Feng estimates that he will need at least seven or eight months.

But as soon as the Dark Forge begins to absorb energy, Black Mountain will inevitably be able to sense it.

How to solve this problem, Gao Feng thought of a stupid solution!

Because the space passage has been destroyed, it is now another space like a bubble floating between the positive and negative universes.

Here, it is impossible to enter either positive cosmic space or anti-space.

This means that the upper limit of speed here is the speed of light.

In fact, even at the peak of the king level, it would not be able to reach the speed of light in the positive cosmic space environment. It is impossible for any substance with mass to reach such speeds. Only the formless and substantial divine thoughts can reach the limit.

The environment in the other space is similar to that of the positive universe, and no one can reach the speed limit here. Although Montenegro has a lot of strength, it is not good at speed. He was able to catch up with Gao Feng, all by anti-space shuttle.

Without anti-space, long distances are the best protection.

Gao Feng decided to choose a direction and speed as fast as possible. Fly until the Dark Forge starts again.

It's a bit stupid, but it's undoubtedly the safest and easiest to implement!

Even if Montenegro knew that he wanted to use this method, there was nothing he could do. The alien space is too vast, and even if Montenegro can choose one direction to fly, there is only a very small chance that it can be in the same direction as Gao Feng.

Because it is not a matter of the four directions here, any deviation of the angle, to tens of millions or hundreds of millions of kilometers, the distance between the two sides will be a huge number.

For the sake of safety, Gao Feng first used the void state to fly north. The north here is also in terms of the position of the sun.

After flying like this for half a month, Gao Feng activated the thunder and lightning wings and galloped at the fastest speed.

After the lightning wings are fused with the Aurora Stone, it can be called one of the most powerful flying light armors. Gao Feng is fully exerted, and the speed can reach at least one million kilometers per hour.

Gao Feng's brain emptied everything, and when he was tired, he stimulated the golden light stone. With more than 300,000 golden light stones in his pocket, Gao Feng could squander them wantonly.

For life, for victory, in the vast and endless world, Gao Feng has been galloping forward and galloping.

Historically, there has probably never been a Golden Light Armor Master who has done this.

Pure, continuous flight, Gao Feng's mind gradually emptied everything. Flying became his instinct.

In this process, Gao Feng had an extremely subtle understanding of the thunder and lightning sword wings and flight.

In this special state, Gao Feng's tired mind and body gradually adjusted, and his state became better and faster.

All the secret techniques that I have learned in the past have also been re-experienced in pure flying.

One day, Gao Feng only felt a shock all over his body, his muscles and bones crackled, and the source force pool in the spiritual core was like a tsunami, and the source force grew rapidly in the turbulent fluctuations.

Gao Feng was pleasantly surprised to find that unconsciously, he had entered the Golden Upper Rank.

The greater the force, the faster the speed. Gao Feng did not change his strategy, but continued to fly forward.

The sun rises and sets, and dozens of days have passed.

The spiritual core of Black Mountain, which was wandering around, suddenly shook and sensed the breath of the dark furnace.

He couldn't help but be ecstatic in his heart, he had been waiting impatiently for this time.

"Look where you're going...... Montenegro muttered to himself and sped away in that direction, flying for a long time, but the breath of the dark furnace was still extremely far away.

"Something seems wrong!" Montenegro faintly seems to have something strange happening!
