We are engaged in scientific research in the ancient martial arts world

After everyone rested in place for a while, they set off on the road again.

This time, Wang Qingyang did not compete with He Suyi on his foot strength. Instead, he deliberately slowed down his pace and walked side by side with the rest of the group.

The area of ​​Red Copper Island is very large. According to Li Yu's visual observation, it is at least comparable to the area of ​​the entire Leisure City.

This also surprised him very much. Because, in his previous expectations, he had always thought that the small island in this world should not be very big.

He could judge this from the map given by Lan Wujiang.

After all, on this map, the outline of the entire continent is clearly depicted.

With his knowledge and eyesight, he can easily understand the approximate area of ​​this continent.

But what he didn't expect was that the people in this world had such poor visual abilities.

It is obvious that the red copper island marked on this map is only the size of a fingernail.

But after he actually landed on the island, he discovered that the island was actually comparable to the area of ​​a leisure city.

However, the Leisure City marked on the map is as big as half a hand.

This is completely disproportionate. Therefore, Li Yu's previous estimation was misled, leading him to believe that this continent was very small and the Red Copper Island was just a tiny place.

This discovery made Li Yu extremely happy for the decision he had made before.

If he hadn't come to investigate in advance, maybe he would have suffered a lot when he came here to land for combat in a few years.

Fortunately, he and He Suyi came here in advance this time to conduct a thorough investigation of the place.

It is still too early to start the battle. After this inquiry, after returning to the army.

He will make corresponding adjustments to a series of deployments and the training direction of soldiers to better face future landing operations.

After everyone marched for nearly half an hour, they finally encountered the first sentry post after landing on the island.

This sentry post was built on a rock belt, and the wooden structure sentry tower was built among a large pile of rocks, which provided a natural protective barrier for it.

There are not many people on guard duty, only three people. Out of caution, Li Yu quietly released his spiritual consciousness and searched around the sentry tower.

After several searches, Li Yu finally confirmed that the sentry here was indeed what they saw, with only three people on duty.

In order not to alert the enemy, several people also suppressed the sound of their footsteps and tried their best to avoid the guard tower.

After half a stick of incense, everyone completely moved away from the surveillance range of the sentry tower here.

Out of caution, everyone marched for nearly half a stick of incense before stopping completely.

At this time, Li Yu took out a small piece of wood, a few pieces of paper, and his pencil.

He began to describe the topography of the island on paper, and also marked the sentry posts he had just met.

Seeing that Li Yu was so focused on describing the terrain at this time, everyone was waiting patiently on the sidelines without making any noise for fear of disturbing him.

After waiting for about half a stick of incense, He Suyi became impatient, so she took a few steps closer to where Li Yu was.

Li Yu, who was concentrating on drawing the map at this time, had no intention of caring about her at all and allowed her to stop and watch.

He Suyi carefully observed the terrain map drawn by Li Yu for a while, and gradually she was surprised by what Li Yu drew.

She had never seen anyone draw a map so vividly.

Even the shoal where they landed just now and the rocky belt around the sentry tower became lifelike in Li Yu's writing.

In addition, she also discovered that the pen Li Yu used was not the brush she usually came into contact with at all.

It was a pen that she had never seen before that did not require dipping in ink. This discovery made her very interesting.

But Li Yu was currently concentrating on drawing, and it was hard for her to ask him at this time, so she could only wait silently.

After burning a stick of incense, Li Yu finally recorded in detail the path they had taken and the sentries they found in the form of sketches.

After discovering that Li Yu had stopped writing, He Suyi couldn't help but ask.

"Master Li, your way of drawing is a bit special!

I have never seen anyone draw a terrain map so lifelike. "

"This method of drawing is my private secret. It has never been shown to outsiders. How could you have seen it before, girl?"

Don't hide it, girl. Li's drawing skills were revealed in front of outsiders today!

Miss He, you are really lucky! It can be seen that Li does not teach secret techniques! "

"Tch! I don't care about your painting skills! I praised you a few times and your tail is raised to the sky?

And, let me ask you! What kind of treasure is this pen you use for drawing?

Why can you draw colors on this paper without staining it with any ink? "

"Hahaha... It turns out that Miss He is interested in this! The name of this thing is: pencil.

It was something Li accidentally invented while refining ore.

Not much of a treasure! If you like it, girl, Li will give you one!

I can make as many of these things as I want. "

"Is this true?"

"Of course I take it seriously. Then, this pencil belongs to you now."

After that, Li Yu delivered the pencil in his hand directly to He Suyi.

When He Suyi saw that Li Yu actually gave her this magical pen that did not need to be dipped in ink, she immediately took it without any intention of being polite to him.

"Li Yu, I'm starting to envy your brain now!

Tell me, how did your head grow? Why do you always come up with weird things?

Almost everything you make is rare and rare that I have never seen in my life!

If I had half the brain you have! I don’t need to work so hard anymore, running a business of licking blood from the tip of a knife!

It would be great if I went into business and became a rich man! "

"Girl, these words are different! You are a powerful warrior in the Martial Realm, how can you say such discouraging words?

In Li's opinion, the Yamingxuan the girl is currently running is quite good. It's not as bad as what you said, girl! "

"You know what a ghost you are! You don't know how expensive firewood and rice are when you're not a householder. I really worry a lot about the survival of Yamingxuan!"

Don't look at my high level of martial arts, but you think that in this Yamingxuan, I am just a hands-off shopkeeper who only practices in seclusion all day long!

In fact, I personally take care of everything in Yamingxuan.

Do you really naively think that you can gain a firm foothold in the Western City just by virtue of my reputation as a venerable person?

Stop dreaming! This girl's martial arts realm is indeed rare in this continent!

But it’s not invincible! It’s not like there aren’t old monsters that are several times stronger than this girl!

Not to mention the distance, within this Leisure City, as far as I know, there are no less than three powerful people in the Martial Master Realm!

This is without including those old guys in the Ouchi Palace!

So, you say, can the name of a venerable person really scare people?

You can bluff for a while, but you can't bluff forever! In terms of business, there are many places and many connections.

I still have to sort it out myself to ensure that I, Ya Mingxuan, have a place in the West City.

Doing business is not just fighting and killing in the arena! The twists and turns in human relationships can be very complicated!

never mind! Even if I tell you, you won’t understand! You, a young man with a well-off background, cannot understand this girl’s difficulties! "

"It seems that Mr. Li thought that doing business in Xicheng was too simple!

Li learned a lesson from what the girl said today! "

"Hey... don't, don't, don't! I don't dare to preach to you! You are much smarter than me!

By the way, tell me about it! How is this pencil made?

Why is it so magical? You can draw colors without any ink! "

"Li can only briefly explain the principle of this pencil to the girl, but it is not convenient for Li to describe the specific materials used and the formula!"

"It doesn't matter, it doesn't matter! You just need to tell me why it can be so magical!"

"Actually, the principle of this pen is very simple. Girl, you can understand that I used a piece of wood to make the shape of a pen.

Later, a special material that can draw colors is added to this piece of wood, which can be used as the "refill" of this wooden pen.

You can also understand this core as a stone that can leave color on the paper!

After my processing and polishing, it turned into the shape of a "pen core", which I stuffed into this wooden pen. "

"Oh~ I see! If you explain it like this, I will understand!

It turns out that making this pencil is so easy! The key is actually the "pen core" in the middle of the piece of wood.

As long as you find materials that can leave a mark on paper, in fact, any kind of things can be made into pencils in this way!

This girl, you understand it this way, right? "

"Well...how should I put this? Miss He, if you understand it this way, there is indeed no problem.

In theory, it works! "

"Okay, I got it~ Thanks! Li Yu!

In the future, I will also pay attention to see what stones can make white paper dyed with color!

Then I can make my own pencils! "

"Haha! As long as you are happy! Then Li wishes the girl to find such materials as soon as possible and make your own pencil!"

"Hahaha, I'll lend you a favor! This girl is really a genius!"

Li Yu looked at He Suyi holding the pencil in her hand, looking as happy as a little girl who got a new toy.

He couldn't say anything more, so he didn't bother to remind her that the material for making pencil lead was very hard to find.

Even if she did find it, it would be impossible to make pencil lead.

After all, she didn't know how to mix the other materials for pencil lead or the ratio of the materials.

Therefore, the "simple" production method that she thought did not exist at all!

If she could make pencil lead with just a few words from Li Yu, then that would be a real ghost!

After the two ended their conversation, they embarked on the journey again.

Since this island is nearly as big as the entire Leisure City, everyone knows that it is impossible to explore it all tonight.

After the few people found out the exact locations of several sentry posts, they decided to find a hidden place, hide there temporarily, and take a good rest.

At this time, it was only about two hours before sunrise.

Daytime is not conducive to their movements, so they must find a safe and hidden place to hide before sunrise.

Otherwise, once daybreak comes, their figures will be easily exposed to the enemy's sight.

After more than an hour of searching, everyone found a large group of volcanic rock gravels under a volcano, and in this gravel group, there were many naturally formed caves.

The interior of these caves is intricately connected and extends in all directions, which is very beneficial for hiding one's body.

After a few people entered these caves, they walked along the winding and rugged roads inside the caves for as long as it took to burn incense.

Finally, we lowered ourselves under a huge rock formation and found an extremely secluded place to stay.

This place is quite hidden, even if someone passes by the path inside the cave, they will not notice it.

Because this place is completely blocked by several huge rocks. When you look down from above, you can only see these large black rocks.

It is impossible to observe that there is an open space at the bottom of these large rocks that can accommodate several people.

After a few people settled here, Li Yu took out some dry food and water from the storage bag and distributed them to everyone.

Due to the hasty departure this time, he did not have time to prepare more rations, so he could only make do with scones made from these green wheat.

These scones have been in stock for a long time. Ever since he led the army and left Gulan City, he had never touched the dry food.

Now, it just comes in handy. A few people just sat cross-legged on the ground, drinking water and nibbling on the hard and bitter green wheat scones.

Crops like green wheat actually existed in the world where Li Yu originally lived.

However, in the world he was in, green wheat had long been improved by advanced agricultural technology, and it was not as bitter and astringent as this wild green wheat.

On this continent, the majority of people are still poor. The poor often cannot afford more expensive refined wheat, wheat, rice, and other grains.

Therefore, they often go to the wild to pick some food that can satisfy their hunger and take it home to make porridge or make scones.

And this wild green wheat is one of the most popular plants on this continent among ordinary people. It has a very high starch content and a long shelf life.

The production process is also very simple. You only need to dry it in the sun, peel it, and grind it into powder, which can be used to make scones.

The scones baked with green wheat flour have a faint fragrance unique to plants, and can be stored for a long time without deteriorating or rotting.

Therefore, green wheat sesame cake is also one of the favorite dry foods of businessmen and knights who travel all over the continent.

Its storage period, its ability to satisfy hunger, and its absolutely low price are unmatched by white flour steamed buns, meat buns, millet, rice, and other grains.
