Ye Ci was simply stunned.

It looked like several pieces of marble had been damaged by Chu Fan's violent test, but the places connected with cement were still strong and inseparable.

"This... this thing is so strong, how long does it take to dry in the sun?" Ye Ci swallowed in shock and asked the biggest question in his heart.

"Two or three days." Chu Fan shrugged and replied casually.

"Only two or three days?!" Ye Ci's tone instantly rose an octave.

Chu Fan frowned, his eardrums were almost broken by her old man, "What's wrong? Is it very slow?"

This is Chu Fan's conservative estimate.

In his memory, the cement in his hometown had more surfaces exposed to the sun, and if less materials were used, some could even be dried in a day or two.

Therefore, in Chu Fan's opinion, the cement he invented in this world did not dry particularly quickly.

"Slow?!" Ye Ci almost didn't come back in a breath, "Did you know that in our place, the best yellow mud needs to be dried in the sun for more than ten days, and during this period, we often have to burn some hay next to it to dry it?

How fast?"

More than ten days, no wonder there are so few magnificent buildings on this continent.

The only tallest building he has ever seen with his own eyes is the auction house in Yuncheng.

And the strength is also very average. When Chu Fan was assassinated by those assassins last time, the auction house was damaged by the security guards who arrived later.

It is said that it has been repaired until now, but it has not been repaired yet.

Not to mention that the repair process took longer than expected.

Even the strength of the building is a little too shabby.

After a little fight, it was completely messed up.

If this was placed in a sect, it would take two days of practice to repair the house.

And the reason why Chu Fan values ​​these cements so much is naturally because what he wants to build is not an ordinary house.

But a real military fortification!

He had a hunch that the next time the demon army came, the demon sealing wall would probably not be able to hold.

The last attack by the Snake Tribe troops had already exposed the major shortcomings of the Demon Sealing Wall.

That is, if the defensive force out of the city to fight is small, no matter how strong the city wall is, it will be useless.

In addition, the construction height of the demon-sealing wall was too high, and the people on top of the city lacked effective long-range weapons and were unable to form a fighting force on top of the city.

In other words, no matter how tall and strong the demon-sealing wall is, if Chu Fan and the personal guards had not turned the tide last time, it is estimated that the demon-sealing wall would have been broken long ago.

And now, presumably the demon clan's experiments have revealed the details of the demon-sealing wall.

Therefore, Chu Fan had a hunch that the next time he attacked, the demon sealing wall would most likely be broken.

When the time comes, the towns closest to the Demon Sealing Wall will definitely be the first to suffer.

The problem is, those towns will naturally have Tianmeng people evacuated in advance.

But there are many sects closer to the Demon Sealing Wall!

Tianwuzong is one of them!

The demon army marched from the demon sealing wall to Tianwuzong, and it only took a day at most to arrive.

Although Tianwuzong has countless masters and the Four Saints Thousand Killing Formation it has deployed, it is very likely that it can withstand the attack of the demon clan.

But who is Chu Fan?

The person who uses the word "gou" to the fullest!

In his eyes, for such a dangerous defensive battle, it would not be too much to prepare ten thousand more hands.

Therefore, modern defense fortifications were put on Chu Fan's agenda.

In addition, there are now magic weapons like cement, not to mention fortifications, even the otherworldly version of the Great Wall can be made by hand!

He is so arrogant, huh!

Looking at the cement in front of him, after a series of tests, Chu Fan was quite satisfied with the effect of the finished product.

Therefore, with a stroke of his pen, Chu Fan immediately issued his first order since returning to the position of sect leader.

Summon good mortals like carpenters and masons to come up!

Now that Ye Ci has the power, Chu Fan only needs to give her the order and she can execute it immediately.

Ye Ci just asked, "Why are you summoned to the mountain?"

Chu Fan smiled but did not answer, turned around and entered the laboratory, and began to plan the Tianwuzong's territory.

The previous sketches of building fortifications had been generated in Chu Fan's mind many times.

Therefore, Chu Fan just drew the thoughts in his mind.

But there will still be some time before the craftsmen are summoned to the mountain, and some modifications need to be made during this period.

Therefore, the sketch Chu Fan has not yet handed over and is still kept in the laboratory.

After finishing the sketch, Chu Fan set his sights on another pile of minerals transported back from Niutou Pit.

Diamond Carbon!

Next, comes the most important thing.

Last time, outside the demon sealing wall, the heartless cannon showed off its might.

At that time, Chu Fan already wanted to build a batch of spiritual fire cannons.

If there had been such a group of spiritual artillery stationed at that time, that battle would not have been so difficult.

And what made Chu Fan determined to create the technology tree of spiritual fire cannon.

It was the same feeling of powerlessness displayed by the spirit fire gun when facing the monster-turned-Ye Buqun last time in the ring.

I have to say that the blue pill that Ye Buqun took was really powerful.

An ordinary human in the Martial King Realm, after taking it, will have the regeneration ability at the level of the Snake King.

You know, for the Snake King to have such a powerful ability, it would take people tens to hundreds of years to develop it.

Therefore, Chu Fan still had many questions in his mind.

That was Ye Buqun's blue elixir. Who gave it to him?

For an evil elixir that can possess such power, the forces behind it must not be weak.

If that's the case, then who is Ye Buqun working for?

Who is the mastermind behind it?

There are many questions that Chu Fan cannot solve at the moment.

The most important thing is, if that evil pill can be mass-produced, how can I cope with it?

Last time, I personally took action, and due to luck, the opponent underestimated my strength and confronted me head-on, so that I could kill him instantly.

But what about next time?

In other words, what about a hundred monsters who have taken the evil pill at the same time?

There is no doubt that if the number is large, even if all the guards are deployed, the power of bullets alone will not be able to keep up with the speed of their regeneration!

However, since the spirit fire gun can be forged.

The more powerful spiritual fire cannon is of course not a problem!

No creature can survive the fire of the Spirit Fire Cannon.

If there is, then give it another shot.

Chu Fan was confident that as soon as the spiritual fire cannon was released, he would no longer have to worry about that blue evil pill.

No matter how big a monster he transforms into, once he enters the soul, my mother no longer has to worry about me not being able to kill the transformed monster!

With expectations in mind, Chu Fan immersed himself in the realm of selflessness and devoted himself to replicating the Shenwu Empire's special product - Long Steel.

It has to be said that the classics from the Shenwu period that Lu Zhan had collected before are truly everything you need.

There are all kinds of things that are spread among the people, collected by sects, and sold on the black market.

Moreover, there are more than ten kinds of Longgang forging methods recorded in it.

But the general forging methods are pretty much the same.

Chu Fan believes that as long as he has patience and tries one by one, he will eventually be able to test out the true craftsmanship of the Shenwu Empire.
Chapter completed!
