Cement is the best binder, easy to source, simple to make, except for one process requirement.

It is required that the calcination temperature should reach 1500 degrees, which can melt the iron into molten iron.

It was also a temperature that William couldn't reach even after racking his brains.

He didn't have a Flame Witch to help him raise his temperature.

William had no choice but to settle for the next best!

In William's previous life, ancient Rome used volcanic ash to make the first cement, and the adhesion was good.

However, there are no volcanoes in the Dicas, at least not at least not at the moment William has found one.

Then this method also ends in nothing.

In ancient China, the binder was made of triple soil and glutinous rice juice, and the adhesive made in this way had an amazing effect and was not inferior to modern cement.

Glutinous rice juice William doesn't have it, not to say that he hasn't seen it in this world, just say that there is such a thing as glutinous rice, and William estimates that he can't afford it.

He was now a minor nobleman with just over 800 pith gold coins.

However, Sanhe soil inspired William that modern cement could not be made, but lime mortar was not a big problem.

Lime mortar is made by mixing lime paste and sand, and mainly relies on the gas hardness of lime to obtain strength.

Lime paste is hydrated lime, which is calcined into quicklime by limestone at high temperature, and quicklime will become mature lime with excess water.

Although calcined limestone requires high temperatures, the temperature is not as high as that of calcined cement, and sealed kilns made of bricks are sufficient for this need.

However, the bricks are still being fired, and this lime brick kiln is still waiting for a while.

However, the crushing of limestone can be carried out first, and the calcination of crushed limestone will be more sufficient, and William sent dozens of villagers to do this work.

Of course, it's all for money.

Of course, every job requires a person in charge.

Old John was tired enough to manage the porters and bricklayers alone, even with Eddie's help.

Charles was busy making spears with Merton and didn't have time.

So the head of this stone crushing was handed over to old Gretel, who had recently taken refuge in him.

Old Gretel is as youthful as an old tree blooming, and he works very actively.

As for William, after putting these things in order, he put all his energy into training.

He summoned the remaining six members of the Guardian and passed on the Knights of Dicas's breathing method directly to them.

This is a reward for their loyalty.

And then the reward is not so easy to take.

Swordsmanship with the knight's breathing technique is even more difficult to practice.

They are again mired in more brutal devilish training.

Even with the indirect guidance of the Magic Mirror, it took a week for all the members of the escort team to carve this set of knightly exercise methods into their bones and become an instinct.

And this is based on the almost non-stop cultivation of the six members of the escort team.

The results of the complete knightly workout are gratifying.

In the past seven days, Jacques Potter's physical fitness has improved significantly, and his physique has increased by 0.1 to 1.5, which has reached the minimum standard for implanting life energy seeds.

William was not stingy, and on the spot, he split a part of the life energy circling in his heart and turned it into the form of a life energy seed, which was injected into Jacques Potter's body.

It warms Jacques Potter's body little by little.

At the same time, it will also allow Jacques Potter to become familiar with this power step by step, and stimulate his own potential, so that one day he can completely activate his own life energy and become a true knight.

After receiving the seed of life energy implanted by William, Jacques Potter knelt down for William on the spot and swore allegiance, his eyes full of burning emotion.

Jacques Potter knew what William had given him!

It is the key to class leapfrogging!

William accepted Jacques Potter's allegiance with peace of mind, from the bottom of his heart!

The other five guards also had a certain improvement in their physical fitness, but they couldn't compare with Jacques Potter, who was born with divine powers, so they could only look at Jacques Potter who had become a reserve knight with envy, and at the same time, they were ruthless in their hearts and devoted themselves even harder to training.

A mere six-man escort will not be able to meet the demands of the coming big war.

William needed more warriors, and the village of Nisse needed more strength.

As a result, a new recruitment notice was posted.

This time, William relaxed the recruitment conditions, both in terms of age and physical fitness.

In a few days, thirty more people were recruited in the village.

The thirty men were divided into six teams, each with five people, and the six guards were the squad leaders, each with a spear, and the six guards were responsible for training, and William was only responsible for the overall assessment.

Each new member of the team was taught knightly swordsmanship, and was trained with a spear as a sword.

However, this time they were not so lucky, they were guided by William and the Magic Mirror, they were only taught by their own team leaders.

Some squad leaders teach well, and some squad leaders teach averagely.

Some new players learn well, and some new players learn to move.

After a period of time, William was very surprised to find that the strength of the team members taught by Jacques Porter, the most powerful team leader, was the weakest, and Mark, who was originally the worst in physical fitness, taught the team members better than the other team members!

This made Jacques Potter very dissatisfied in his heart, and increased the intensity of training, making his new players cry tired and cry for their mothers.

The other five squad leaders saw it, naturally they would not be indifferent, each squad leader wanted to make some achievements to show William, needless to say, they tacitly increased the training intensity for their own team members, so all the new team members lived a miserable life.

In any case, the deafening sound of the 36 members of the escort team wearing uniform training every day still raised the sense of security in the hearts of the villagers of Nisse.

Time passed little by little, and after ten days, the first batch of bricks came out, and about 70% of the bricks were usable.

With this batch of bricks, William was able to build an earthen kiln with high heat resistance and sealing, and began to fire quicklime.

Of course, the firing of bricks cannot be stopped.

With quicklime, it becomes lime paste by adding water, and then mixing it with sand to make lime mortar.

With the addition of lime mortar and bricks, the construction of the wall in the small village of Nisse can be officially started.

However, imagination is beautiful, life is cruel.

The production of lime kiln is not complicated, as long as you pay attention to the tightness!

Just as William rolled up his sleeves and prepared to make a big move, Old John told him that both the brick and lime kilns had to be shut down.

William asked him why?

Because there's no firewood left! Old John replied helplessly.

The wheat stalks in the fields have been burned, and the trees are cut down too slowly to keep up with the burning of the kilns.

William had to take time out to solve this energy problem.

Coal or oil is the perfect solution, but no villagers have ever found coal, let alone oil.

William didn't dare to let the magic mirror scan, for fear that the magic mirror would accidentally consume too much energy, and he would fall into a deep sleep, and he would have nowhere to go when he cried!

Then the target is still on the trees in the forest.

It's just that the rate at which trees are cut down needs to be improved.

There are only three axes in the whole village, which is why the speed of felling has not been able to go up.

This is different from transporting soil, without baskets, you can use other things instead, there are still ways to transport soil, but without axes, you can't let the villagers cut down trees by hand.

After all, not everyone is the little Goku in Dragon Ball, who can chop wood with his hands!

Need to add tools for chopping wood! William came to this conclusion in his heart.

Go to Ciudad Patras to buy? William thought to himself, and then shook his head.

Axes are available in Patras, but they are not very efficient at cutting down trees, and they are expensive as a weapon.

William needed a more efficient tool for felling trees.

He immediately thought of saws.

You can't do it with a chainsaw, but you can give it a try.

William called in the blacksmith Eddie and told him about the construction of the saw.

Addon thought for a moment and said he could make the saw, but he needed an iron stove.

The iron furnace is simple.

The bricks are ready-made, and the lime mortar is not yet available, but the mud from the Kadim River, combined with the grass and wood ash, makes something that has a good bond.

In two days, a simple and ugly iron furnace was made, filled with firewood, and after it was lit, Eddie put the iron rod that William had first obtained from the Scarlet Hand's killer and calcined it.

When it was almost burned, he swung the hammer he had brought from the city of Cell, and began to forge it.

The iron rod was thinly sliced, the two sides were used to make sharp serrations, and when cooled, a wooden handle was attached to one end of the sheet, and a new wooden saw was baked.

The efficiency of sawing a tree is much higher than that of an axe, and it used to take half a day to cut down a tree, but now it takes a candle to burn.

Moreover, it consumes much less effort than using an axe.

In the past, the villagers used axes to cut down a tree, and they were busy for a long time, and they were half tired to death.

Now with a saw, it's much easier, not only fast, but also has spare energy!

The saws were well received by tree cutters.

Eddie, who was praised, was very excited, striking while the iron was hot, and forging the saw non-stop.

For a while, the villagers passed by Eddie's "blacksmith shop" and heard the cheerful sound of "dang dang dang".

A sawsaw was produced by Eddie, and the efficiency of felling trees in the village of Nisse increased at a straight upward rate.

The villagers of this era have no awareness of environmental protection and do not know how to protect the environment.

William needed a lot of firewood, and the villagers naturally had the principle of proximity.

So, in the forest around the small village of Nisse, low wooden stakes appeared.

These are trees that have been cut down by the villagers.

Walking out of the small village of Nise, the villagers' vision is much clearer, and as far as the eye can see, it is no longer a forest full of oppressive forces and unknown fears.

With enough firewood, the firing of brick and lime kilns continued unswervingly.

New bricks are being created all the time.

New quicklime is also calcined.

The convoy is training hard, the villagers are hard at work, and the small village of Nisse is full of life, like a train on the right track, slowly but surely moving towards the goal......

Everything seems so beautiful.

However, on the morning more than twenty days after the West Knight's departure, before the sun came out, the magic mirror shook violently.

"Master, master, there's a group of unknown people approaching."
