~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Qianshan is the branch of Changbai Mountain, facing the Bohai Sea in the south and Changbai Mountain in the north. The peaks are spreading to the ground and thousands of scepters are facing the sky. Because the total number of peaks is nearly a thousand, it is called "Qianshan". {}

In the thousands of mountains in May, pear blossoms are blooming, green eyes are full of green, pine waves are gushing, and cool breeze is refreshing. When you climb to the main peak, you can see floating clouds like the sea and mountains like reefs, and you can feel like climbing a mountain like a sea.

Ma Hanjianci, accompanied by Lu Dai and Jia Cheng, only brought a hundred entourages and climbed thousands of mountains under the guidance of the marching. The thousands of mountains were just many, but not high, and the highest main peak was only more than 700 meters above sea level. With Ma Han and others' footsteps, they could easily go up and down in half a day. At noon, they arrived in front of a waterfall.

The waterfall is high and steep, and the water is turbulent. At first glance, it looks like a slanting ladder. There is a huge rock at the entrance of the waterfall, which divides the waterfall into two strands. Two jade dragon-like water columns fall from the sky and rush into the deep valley, splashing waves several feet high, the sound is like thunder, the water vapor is as fog, and the scene is spectacular.

Ma Han was on the top of a mountain peak hundreds of meters away from the waterfall, looking at the rocks, and his entourages had already spread a few miles away to watch. Ma Han seemed to be watching the scenery in a daze, but in fact, he was really "studying" rather than watching the waterfall.

Of course, Ma Han came here not to travel around. He didn't have that much time and didn't have that good interest. He just wanted to find a quiet and elegant place that was suitable for meditation and recall some things - to be precise, some information, information about steelmaking forging.

With Ma Han's background in his previous life and the path he took later, he could not get into the eight-pole of steelmaking forging. He would not have any information on this, but don't forget that he had a robotic arm... After Ma Han installed the robotic arm, he had several weeks of adaptation in the test center. Of course, he had to learn in detail about the special alloy of his robotic arm. As a result, the doctor gave him a thick book "The History of the Development of World Steel".

It is related to the source, structure, and performance of the limbs that will accompany you throughout your life. No matter how big a man is, he can only look at it with his nose pinched.

Since it is the history of steel development, of course we will start from the beginning, from ancient times to modern times, and the future.

At that time, Ma Han was eager to understand the modern part related to his robotic arm. He basically just glanced at the previous ancient part and only looked at some interesting records, so he really didn't remember much. But the technical difficulties he faced now were part of this vague impression. It was really a pity that he would hate when he was used!

Therefore, Ma Han planned to find a quiet place, recall and sort out in detail, and see if there is anything to learn from. This time, he has really thought of some things, such as the steel filling method and the Su steel method.

According to the development of iron treatment technology, the steel filling method was followed by the steel filling method. Then there was the more advanced and convenient Sugang method. However, these outlines are easy to remember, but how can they remember the specific content? How to pour steel filling? How to Sugang Su? Ren couldn't even think of it, but who made him not care about it when he first saw it? However, he did not get anything. At least he remembered some interesting examples of ancient sword-forging and knife-forging. Perhaps experienced craftsmen could get useful inspiration from it.

While Ma Han was thinking, the entourage's report came from behind him: "Report to the lord, the Ma Worker Officer has something to ask for.

Ma Jun? Well, this person's mind is full of all kinds of machinery and he will not easily see people. When he comes to ask for a meeting, it is probably because of the job that has a good reputation.

How long has it been so fast? Ma Han was slightly surprised and summoned him immediately.

Three years later, the thin boy was already a gentle and honest young man with a size of seven feet. With the conscious guidance and strong support of Ma Han, the first inventor and skilled craftsman of the Three Kingdoms entered the path of research, invention and creation faster than the original history, thus achieving greater achievements. In history, Ma Jun was precisely because of the coldness of General Cao Shuang towards technology at that time that many of his important inventions had ideas, but ultimately failed to realize, including the improvement of the most famous profit and loss crossbow, which is regrettable.

Although Ma Jun spoke much more fluently, he would not say anything politely. After seeing Ma Han, he presented a picture directly. When Ma Han opened it, he found that it was a water drainage, that is, a structure diagram of the hydraulic blower.

The water drain designed by Ma Jun is a huge wooden wheel erected on the shore of the turbulent water flow. The impact force of the water flow drives the wooden wheel to rotate, and the transmission mechanism drives the rotation of the row, thereby blowing the powerful wind into the blast furnace. The three parts of the power mechanism, transmission mechanism and working mechanism included in this hydraulic blower are designed quite perfectly and maturely.

Ma Han was very surprised. This Ma Jun actually had such a quick creative thinking, which is really amazing!

When Ma Jun saw the joy on Ma Han's face, he also said the truth: "In fact, Jun is also suspected of taking advantage of tricks. Bi Yilang (i.e., Bi Lan of the Eastern Han Dynasty) had already invented it, but it was too rough and Jun had already intentionally improved it, and he had been thinking hard for more than a day..." After that, he presented another original picture.

Ma Han suddenly realized, no wonder he designed such a perfect pattern in just one day and night. It turned out that he had an idea of ​​this. After taking the original picture presented by Ma Jun, he couldn't help but stare at it. Isn't this the most common keel waterwheel in farmland in later generations? Could it be that it was invented by Ma Jun?

In fact, it is true. The keel waterwheel that has been passed down for nearly two thousand years is one of Ma Jun’s important inventions and has always been the most important facility for ancient agricultural irrigation.

Since Ma Han had become the largest landlord in Liaodong and had tens of hectares of fertile land, he generously rewarded many of the land for the soldiers who made contributions in this battle. Ma Jun also obtained a hundred acres of land for his contributions to building crossbows.

Due to the inherent land nature of the ancients, Ma Jun has been running into the fields these days and is very concerned about the unfavorable problems of farmland irrigation. As the saying goes, it is necessary to invent inventions, and its vital interests have made Ma Jun invented the keel water truck earlier than the original history.

Ma Han has been so busy that he kicked the back of his head that he has not had time to patrol his own land, so he didn't notice that there was no such important agricultural facilities in this era. After seeing this, he immediately made a decision: "Deheng, leave this matter to you, go to the warehouse to collect five thousand gold. Build a thousand such water trucks for me, and I want the entire Liaodong land to be full of this thing!"

Ma Jun was so excited that his invention and improvement were so highly praised and strongly supported by his lord. He suddenly felt like a close friend. He was so excited that he stuttered again and couldn't hold a word for a long time.

When I was in a good mood, a warning voice came:

"There are assassins!"

"Come around quickly and catch these assassins!"

Assassin?! Ma Jun and all the entourages were shocked. They hurriedly protected the Ma Han ring in the center. However, Ma Han smiled and quickly untied the sac (the instrument that holds the bow) and took the bow in his hand. After taking Liaodong, some people were dissatisfied or held grudges and took risks. It is not surprising that they were those guys who were not afraid of death.

Ma Han pushed away his entourage and strode towards the source of sound. The entourages urgently protected their left and right and made a way forward. Soon, they found an assassin surrounded by dozens of entourages in front of the waterfall.

There were three assassins, all of whom were young and thirty years old, wearing short-clad knotted clothes and tied their feet. The exposed arm muscles were very thick. The three assassins faced the wolf riders surrounded by back to back. The weapons they held were all ring-headed swords. One of them was a strong man about thirty years old, carrying a leather knife bag. There were three knives on it, and the one he held in his hand, there were four knives in total - was this guy a assassin or a knife sold?

When Ma Han arrived, he saw two wolf entourages taking the lead and stabbed the assassin with four swords on his back.

The assassin's eyebrows were snatched with his hands, and waved his sword left and right. Two sounds were heard, and the sword and halberd of the wolf cavalry entourage was cut off. The two wolf cavalry entourages were shocked and retreated quickly, but the assassin did not pursue them. The other wolf cavalry entourages wanted to attack, but when they saw this, they stopped.

Ma Han let out a light exclamation. Since he visited the arsenal to inspect the weapons, he attached great importance to his subordinates' equipment. The weapons of these entourages were all distributed by him after personal inspection. Each person's ring-headed sword and short halberd reached at least eighteen refinements, which was higher than the equipment level of the soldiers of the Dahan County and was the same as the equipment of the Beijing troops.

Such a weapon was actually broken by one blow? Well, Eighteen Refining is not very good, it is not impossible to break, but the problem is that the ring-headed knife in the other party's hand was completely unharmed after cutting the knife and halberd. This is surprising.

At this time, another wolf cavalry with a short axe attacked one of the assassins. The axe blade in his hand and the opponent's ring-headed sword were continuously bumped. After both sides retreated several steps, they looked at the weapons in their hand. The ring-headed sword was fine, but the axe blade was like a sawtooth.

The weapons held by these assassins are so sharp!

The lord was by his side, but he could not capture it again and again. The wolf cavalry entourage felt that his face was absent, and some people shouted: "Get on the hook!"

Several wolf riders quickly took off a strange-style shield from the saddle. This shield is roughly the same as an ordinary infantry shield. The only difference is that in the core part is a small circle of iron sheets, with a thorn used to push and kill, and an iron hook extending from the upper and lower sides to hook the opponent's weapons.

This is a unique weapon in the Han Dynasty, called hook inlay. Infantry used a combination of hook inlay and a ring-head knife to easily restrain long pole weapons such as long halberds. However, when the weapon "halberd" was eliminated on the battlefield in later generations, it also withdrew from the battlefield as a targeted restraining weapon. But at this time, hook inlay is still very useful.

The entourages of the wolf cavalry used hook inlay not to hook the opponent's knife, but in fact they could not hook it either. The main reason why they saw the opponent's weapons were sharp, they wanted to block it with this iron shield. As a result, several wolf cavalry with hook inlay approached the assassin, three people and three swords came out together, and the hook stabs on the hook inlay were all cut off. The strong man with four swords on the back even cut the hook inlay inlay in half with one knife, almost slashing the wolf cavalry's arm with hook inlay...

At this moment, the wolf cavalry entourage no longer had a temper and shouted: "I don't care, shoot the arrow! Shoot the arrow!"

The Wolf Cavalry entourage wanted to catch the alive, but then they surrounded them close together. Unexpectedly, the assassin's sword was too powerful and there was no way to do so, so they had to shoot arrows, hoping that they would not be shot to death, and just leave a living mouth.

The three assassins looked terrible in an instant, and the strong man with four swords on his back even hung his sword on the ground. He sighed to the sky: "I didn't expect that Pu Yuan came to Liaodong just to find the pure water of the world. He was regarded as an assassin and died unjustly. He was corpse in a foreign land. How sad!"

Pu Yuan?!

Ma Han was shocked and yelled: "Stop!" (To be continued, please search Piaotianwen, the novel is better and faster! u
