The city is 100 meters high, has a circumference of 40 kilometers, and covers an area of no less than 100 square kilometers.

This is the basic specification of the city that Liang Jing wants to build, which is not big, but it is enough.

Therefore, the number of bricks he needed to build the city must have been extremely large.

To use the rocks in the cave as the city brick material, Liang Jing's workload can be imagined terrifying.

"However, as long as these rocks are used as city bricks, the city built will definitely be strong and durable, at least the innate level existence will definitely not be destroyed, then, even if it is a little harder, it will be worth it."

In the cave, Liang Jing's face was calm, and he meditated cross-legged, recovering his true qi consumption.

For three days, non-stop, with drugs to speed up the recovery, finally, only to hear the terrifying sound of 'boom', a terrifying hole was cut out of the cave, and the space in the cave was inexplicably enlarged, full of people's senses.

A huge black-yellow-brown rock block ten kilometers long, two hundred meters high, and one hundred meters wide fell off from the rock wall, and the entire cave was shaken, violently earthquaked, and the air explosion visible to the naked eye in the air was stirred, and dust and debris burst out......

Such a large piece of rock, with such a large density and weight, the power generated by the collapse is simply devastating.

This surging pressure, ordinary people will instantly turn into anti-powder, terrifying.

Liang Jing in the earthquake storm opened his eyes suddenly, countless everything, the cave seemed to be flashing, and his face showed a look of satisfaction, so many days of continuous consumption, and he recovered his true qi, and his true qi has changed and improved.

What's more, these days of hard work are finally paying off.

Nodding, Liang Jing held down the huge rock, and the next moment, the huge rock disappeared in an instant.

Looking at the rocks in the storage compartment, Liang Jing nodded with satisfaction, "The storage bag and the storage compartment of the 'system' have their own advantages and disadvantages, and I want to match them just right." ”

"Huh? It's ......"

The dust cleared, and Liang Jing suddenly saw that the space after the huge rock fell off was a little strange.

Three or two steps forward, only to see that on the cut smooth rock wall, there are yellow crystal gold shining 'ink spots' like existence, the size of the nearby total is as many as five, reaching out to the largest only two meters square 'ink spots', giving people a feeling of hard and porcelain.

Liang Jing's heart moved, stretched out his hand a little, two red and white flame pillars of laser spray, respectively sprayed on the rock next to him and the 'ink dot', the next moment, under the continuous burning explosion, the continuous light flame attack, the attack strength continued to accumulate, becoming extremely terrifying, the rock began to slowly melt, but the ink dot did not change at all......

It wasn't until there was a pothole the size of an egg in the rock that the ink dots finally began to flicker slightly, changed, began to smoke, and crackling sounds kept appearing, but they still did not turn into powder like the rocks, but slowly appeared cracks one after another.

Liang Jing took out the black dragon giant stick and knocked on it, the 'ink dots' completely shattered and fell to the ground, and the black dragon giant stick weighing more than 3,000 catties hit the 'ink dots' fragments, with a 'poof' sound, the fragments turned into powder, and when they knocked again, there was a 'ding' sound of crossing.

With a move in his heart, he pushed aside the powder, and a piece of crystal yellow and golden metal the size of a small thumb appeared inside, and he pinched it directly, but Liang Jing's face changed suddenly-

Heavy!

It's so heavy!

Such a small metal, even if it does not count the supergravity here, at least it weighs no less than hundreds of catties, which is completely unexpected by Liang Jing.

What kind of density is this?

Looking at the powder where the metal was, the same as the powder that the rock next to him had become, Liang Jing thoughtfully put away the metal, and looked up at the broken 'ink spots'.

The inside was already empty, and the faint light came from inside, and when I got closer, there was a larger cave inside, and there were passages one after another, extending in all directions, labyrinth and vast.

Suddenly, his eyes moved, and he looked around carefully, only to find that there were many potholes and craters on the side, and some shattered, black, yellow-brown rock fragments, obviously affected by the terrifying liliang impact.

This liliang is not at all something that an ordinary innate level existence can cause.

In the middle of it, he picked up a claw-like object, less than half a meter long, crimson and golden.

Liang Jing directly used the [Divine Eye Technique] on it.

Bite!

"Lava Beast Wreckage: Lava Beast likes to devour rocks, ores, and all kinds of metals, and its body is hard and invincible, and its strength is infinite...... The body can condense the geocentric magnetic gold ......"

Bite! ――

"Geocentric Magnetic Gold: A High-Density, High-Strength Mysterious Metal."

And the previous little finger-sized, yellow-panted metal is the geocentric magnetic gold.

Liang Jing searched everywhere, and in addition to more than a dozen 'ink spots', he also found some lava beast remains, but they were much smaller than the previous claws, but the texture was not comparable to the geocentric magnetic gold.

At this moment, his face couldn't help but become solemn, it was obvious that this lava beast should have been killed after the battle, and its body was also taken away, thinking that the other party was coming for the geocentric magnet in the body of this lava beast.

But who is it? was able to kill the geocentric magnet gold, could it be blood disgust?

But although the blood disgust is smart, it is impossible to build a weapon by himself, not to mention, it is not easy to make full use of the geocentric magnetic gold, and it is very difficult to give full play to his attributes, and even he himself may not be able to find a good way except for the synthesis furnace.

This lava beast is obviously not weak, at least judging from its wreckage, this lava beast has reached the innate level, invincible defense, liliang against the sky, and the blood aversion beast may not be able to help the other party, right?

He actually beat the lava beast to the center of the earth, spraying it everywhere.

"Forget it, let's collect these geocentric magnets first."

Liang Jing pondered for a while, and then carefully investigated the surroundings, and found nothing abnormal, so he began to use the Light Flame Technique, burning at the 'ink spots', and collecting these geocentric magnetic gold.

Two hours later, Liang Jing had collected more than a dozen large and small geocentric magnets in his hands, adding up to no less than two thousand catties, and he was collecting a geocentric magnet gold from Zuihou at this time.

With a 'poof', the rock wall shattered and fell off, but Liang Jing did not immediately collect the geocentric magnetic gold in the powder on the ground, but looked directly at the inside of the falling rock wall.

He found that there was really a hole in the underground shijie, and it was very mysterious. I didn't expect that there was a secret cave here, and I immediately expanded the entrance of the cave, and found that it was a rock cave with a length and width of hundreds of meters, perhaps by the strong vibration of the battle between the lava beast and the enemy, and the broken rocks inside fell a lot, and it was very messy.

Suddenly, Liang Jing walked towards the cave, only to see a crystal yellow and golden color appear in front of him, bubbling with bubbles, a one-meter radius of a pool-like existence, the edge of the pool has solidified into a solid state, exactly the same as the geocentric magnetic gold in his hand.

Obviously, these are geocentric magnets.

Next to the pool, there are several broken eggshells with a sparkling color.

Seeing this situation, Liang Jing's heart shook suddenly, "Could it be that this is the lair of the lava beast, and this should be the offspring of the lava beast in front of me, or egg-shaped, but it was tragically affected by the aftermath during the battle." ”

The situation was calculated in an instant, Liang Jing looked at the bubbling sink, his eyes lit up violently, this is geocentric magnetic gold, but it is a good thing. I really didn't expect that there was so much geocentric magnet gold in this lava beast's nursing egg, which was at least a hundred times more than the sum of the dozen or so geocentric magnets collected before.

"I wonder what the temperature is like here? It's been bubbling, and it's been a long time, and only a small part of it has solidified into a solid. ”

Putting away the geocentric magnetic gold for a moment, and the black dragon giant stick in his hand, Liang Jing thought silently, and walked towards the 'pool' with his footsteps.

Suddenly, the black dragon giant stick in his hand trembled violently, and waves of weak, intermittent consciousness fluctuations reached Liang Jing's body.

"Eat...... Delicious, ...... Additional ......"

"This thing is still conscious, this is the first time I have discovered it, is this thing also a demon?"

Looking at the obviously broken black dragon giant stick in his hand, Liang Jing couldn't help but be surprised, this is really a myth, these magic weapons and artifacts can produce spiritual intelligence, it seems that it is really not strange.

In other words, since he had the [Martial God Fist], these thousands of catties of black dragon giant sticks have been a little unable to keep up with him, and they can't be combined with other items, and they are rarely used in ordinary times.

After pondering for a while, Liang Jing's eyes flashed with determination, and he threw the black dragon giant stick in his hand into the geocentric magnetic gold liquid pool, hoping to see the changes in the black dragon giant stick after 'eating' these geocentric magnetic gold.

The black dragon giant stick submerged into the pool, and after a while, the geocentric magnetic gold liquid seemed to boil, and a small whirlpool appeared on the pool, constantly rotating, and the liquid level around it continued to drop.

Obviously, this black dragon giant stick is absorbing the geocentric magnet gold.

Half an hour later, all the geocentric magnet gold liquid in the pool was absorbed, leaving only the solid geocentric magnet gold, and the black dragon giant stick in the middle flashed brightly, and finally disappeared, standing quietly at the bottom of the pool, no longer absorbing the solid geocentric magnet gold.

At this time, the black dragon giant stick did not seem to have changed much compared to before.

Liang Jing stepped forward and grabbed the black dragon giant stick, it was dark and dull, with concave and convex marks on the surface, and a sharp scumbag spur was broken at one end, as always, there was really no change.

However, when he was about to pick it up, his face changed, and he couldn't pick it up.

"Drink! ――”

Liang Jing's arms doubled, his green tendons were exposed, his face turned red, and he wanted to grab the black dragon giant stick with both hands.

But I couldn't pick it up at all, so I could only move reluctantly.

It's so heavy!

The previous black dragon giant stick was originally more than 3,000 catties, and the gravitational force here is very large, weighing more than 10,000 catties.

But now, the weight of this black dragon giant stick is at least no less than 200,000 catties!

In other words, the weight of the Black Dragon Giant Stick has increased by almost twenty times in this short period of time!

If you convert, the current weight of the black dragon giant stick should be about 50,000 catties.
