Alien High Lord

After all, the big black bear can speak without hesitation in the face of a monster that has just been incontinent!

As for why the big black bear let them go, no one knows the specific reason, the only thing that is certain is that it has something to do with Li Fan.

Li Fan had no clue about this.

In the end, everyone can only attribute it to good luck.

……

After that, Li Fan began to count the gains this time.

First, 8 cubic meters of sulfur.

The matter of making black powder is not in a hurry for the time being, so Li Fan asked people to find a cave to store all the sulfur.

This was followed by 25 cubic meters of volcanic ash.

There are about 1 tons of volcanic ash in 1.2 cubic meter, and Li Fan harvested almost 30 tons of volcanic ash on this trip.

It looks like a lot, but in fact it is more than 100 tons of concrete, which is only enough to build the valley entrance into a city gate.

Thinking of the huge amount of concrete that will be needed to build the house later, Li Fan couldn't help but start to have a headache.

Originally, according to the plan, they planned to carry the volcanic ash back many times.

However, the sudden appearance of a big black bear of a level 5 monster completely destroyed their plan. Now who would dare to carry volcanic ash on the volcano?

It seems that the construction of new houses has to be put on hold for the time being.

However, Li Fan does not allow any delay in the construction of the city gate.

As long as the city gate is built well, this valley can be considered theirs, and only this can't make any mistakes.

For this reason, Li Fan immediately found the dwarves regardless of the darkness of the sky, and asked them to make a batch of ancient Roman concrete with volcanic ash.

In this way, at dawn tomorrow, they can just test how high the initial strength of this concrete is.

……

In addition to sulfur and volcanic ash, what Li Fan brought back were the corpses of volcanic ants and black crystals.

The corpse of the volcanic ant was not big, with no flesh at all, and it was worthless except for a first-level magic core.

But their casings are decent material.

Interestingly, perhaps because these volcanic ants often feed on stones and ores.

Dozina and the others took off the shells of the volcano ants and tried to forge them, and found that these shells can be forged into different shapes like metal.

Dozina immediately forged a piece of armor out of these shells.

The result is that this armor has reached the middle grade of the ordinary level. Not only does it have good defensive power, but it is also extremely light, and it doesn't feel too much weight when worn.

The one who reacted the most was Anna.

The environment in which she was born made Anna understand the value of the shell of the volcanic ant in an instant.

You must know that even in the powerful Silver Wolf tribe, most of the fighters can only wear rough leather armor.

If every orc warrior could wear this kind of armor, the combat power of the entire Silver Wolf tribe would be at least a little higher.

Li Fan naturally realized the value of this armor.

If this kind of armor is used to arm their three-race mixed group, it will definitely increase their strength by a bit.

It's a pity that the volcanic ants, like the volcanic ash, are temporarily untouchable because of the big black bear.

In addition, the last harvest of Li Fan and his party was black spar.

This is what Li Fan is looking forward to the most. This kind of black crystal looks precious. It would be great if it is a precious ore.

To Li Fan's surprise, when Li Fan found Aoki and Bai Qi, the two oldest guys didn't even know this black crystal.

Just when Li Fan was about to give up, Alicia who happened to be passing by suddenly said, "Isn't this a photo stone? Where did the young master find this kind of stone?"

"Picture stone? Do you know this kind of stone?" Li Fan handed the black crystal in his hand to Alicia.

Alicia took the black crystal and looked at it several times, and then said with certainty: "Yes, this is the photo stone."

Then Alicia explained the photo stone.

The photo stone is an extremely magical stone, comparable to the witch's alchemy.

It is a magical stone that cannot be thought to be made.

Just because this kind of stone can leave pictures of what happened in the past, it is named photo stone.

Once this kind of stone was discovered, it has been popular for a long time, and the price was even as high as one gold coin at that time.

But then someone discovered that this kind of stone not only needs a steady supply of energy to retain images, but also leaves images randomly.

Maybe you want to keep your own smiling face, but you didn't leave any image after staying in front of the photo stone for several hours, but when you left the photo stone, you suddenly succeeded in leaving an image.

Under the two flaws, the photo stone quickly faded out of people's vision.

Even if it is given to children to play, it is disliked to waste the energy provided by the magic core.

This has led to the fact that no one is willing to pick up this photo stone even if it is thrown by the roadside.

Hearing this, Li Fan probably knew what the photo stone was.

To put it simply, it is a broken camera, which not only needs an expensive magic core as a battery, but also cannot take pictures as you like, and can only take some pictures randomly.

This kind of stone is of no use to Li Fan. After all, if he needs it, he can directly exchange the bond value for a camera. How can he use this rubbish...

"Forehead……"

Li Fan, who was about to say that the Photo Stone is rubbish, was taken aback for a moment, and then he seemed to have thought of something, and a slightly obscene smile couldn't help showing at the corner of his mouth.

The next moment, he hastily saved the photo stone in the space ring carefully.

It's like preserving a huge treasure.

……

Early the next morning, a group of people couldn't wait to test the strength of ancient Roman concrete.

The concrete the dwarves had made last night had roughly set.

After the experiment, everyone was sure that the strength of this concrete was definitely higher than that of plant ash cement.

Moreover, Li Fan also knows that the biggest feature of ancient Roman concrete is that the longer it lasts, the higher its strength. If it can be soaked in seawater, it will not only not rot after thousands of years, but will become surprisingly strong.

With this kind of concrete combined with steel bars, the strongest city gates and towers can definitely be built.

The reason for the city gates and towers is because what Li Fan intends to build is a tower-type city gate.

To put it simply, the lower part is the city gate with doorways, while the upper part is the city tower and the arrow tower.

This classic city gate is definitely one of the best choices for defending against enemies in the era without hot weapons.

Chapter 140 Infrastructure and Reclamation

The construction of tower-type gates mostly required ancient Roman concrete.

However, the most important city gate must not be made of concrete.

And the best choice is of course a steel gate made of iron.

Li Fan originally planned to directly build a gate made of all steel.

But when he did a simple calculation, he found that a steel gate with a width of 8 meters, a height of 10 meters, and a thickness of 0.5 meters finally weighed a whole

jin.

This number really shocked him. To build such a gate, it took several level 3 fighters to cooperate to open and close the gate every day.

Obviously not suitable for them now.

Li Fan can only be like the ancients, using wood as the door and wrapping a thick layer of steel on the outside of the door.

In fact, such a city gate is already very strong, and it is definitely not something that can be easily destroyed by level 2 or even level 3 fighters.

In the end, everyone based on this plan and began to build the city gate.

During this period, Li Fan, who strived for the best, still couldn't forget the gate made of all steel.

Although they can't afford such a steel gate now, it's not certain in the future.

Especially with [Upgrade Potion].

In this case, Li Fan naturally has to plan for the future.

Before that, they took back a total of 100 million catties of iron from the dwarf gathering place.

It looks like a lot, but it is actually only 500 tons, and it will be even less after it is smelted into steel.

After the tower-shaped city gates were built, there were not many iron blocks left, let alone forging the large city gates made of all steel.

"Iron blocks are not enough!"

Li Fan thought that they had enough iron blocks, but now that they saw that they were not enough, he couldn't help but let out a sigh.

The next moment Li Fan suddenly turned his gaze to the south, which was the direction where the dwarves gathered.

At the beginning, Gu Li did not remove all the iron blocks in the dwarf gathering place, because the space rings of Li Fan and Duozina combined were only 13 square meters at that time.

Moving it back and forth took too much time.

In fact, there are still a lot of iron blocks left in the dwarf settlement.

Now that the ice and snow have not melted, it is estimated that the dwarves have not yet returned to the gathering place.

Li Fan squinted his eyes and thought for a while, then he found Gu Li and Dozina.

"We don't have enough iron!"

Li Fan sighed again to Gu Li and Dozina.

Upon hearing this, Gu Li and Dozina suddenly showed speechless expressions. How could they not understand the meaning of Li Fan's words.

However, one of the two was a "sinner" dwarf, and the other was forced to escape by the leader of the gathering place.

Therefore, neither of them had a good impression of the place where the dwarves gathered, and naturally they would not object to what Li Fan wanted to do next.

Seeing this, Li Fan smiled with satisfaction, and then he took out his interspatial ring.

Seeing this, Gu Li knew that Li Fan entrusted him with this matter, after all, he moved all the iron blocks before.

Gu Li took over the space rings of Li Fan and Duozina together.

He habitually looked at the interspatial rings of the two of them, mainly to see if there were any debris inside that hadn't been cleaned up.

At this moment, Gu Li was taken aback for a moment, and the next moment he looked at Li Fan twitchingly at the corner of his mouth, and asked in disbelief, "Why is your interspatial ring getting bigger again?"

Seeing this, Li Fan coughed dryly. With the last volcanic ash incident, he deeply realized the importance of the space ring.

Thinking that the space ring can be used everywhere.

Li Fan finally gritted his teeth and directly upgraded the 25 cubic meter space ring to 50 cubic meters.

For this reason, another 2500 bond points left him, and now he only has 1100 bond points left.

Although the bond value is precious, there will always be some if you can save it, but now it is more important to collect resources.

And now there is this 50 cubic meter space ring, plus Dozina's is 55 cubic meters.

In this way, Coulee can carry almost 429 tons of iron in one round trip, which is a whole

jin.

As long as Gullid carried them back and forth a few more times, they would not be short of iron for a long time.

Gu Li also guessed what Li Fan was thinking, and the corner of his mouth twitched again.

Even if the dwarves' gathering place is built on a mine, and the iron blocks stored there are at most 1000 million catties, as long as he moves back and forth a dozen times, the entire gathering place can be emptied.

Li Fan is planning to let him 'drive out all the iron blocks in the dwarf gathering place'!

At that time, the entire dwarf empire will be shaken by this, right?

Gu Li hesitated at the thought of this, and finally he gritted his teeth and left the valley.

"Done, those bastards at the gathering place cheated us of so many good things, but in the end they only gave us poor-quality ale and a little pitiful table salt. Since you treated us like this back then, don't blame me for doing everything right now."

Thinking of this, Gu Li walked towards the dwarf gathering place without hesitation. He decided that this time, he would evacuate the dwarf gathering place, not even leaving a single piece of iron behind.
