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

Thousands of mountains are the branch veins of Changbai Mountain, south of the Bohai Sea, north of Changbai Mountain, the peaks are uprooted, Wan Wat is facing the sky, because the total number of peaks is nearly 1,000, so it is called "Thousand Mountains".

In the thousand mountains in May, the pear blossoms are in full bloom, the eyes are full of greenery, the pine waves are gusting, and the cool breeze is cool. Climb the main peak, but see the floating clouds like the sea, the mountains like reefs, there is a feeling of mountaineering like the sea.

Ma Hanjian said goodbye to the company of Lu Dai and Jia Cheng, and only took a hundred followers, and under the guidance of the guide, climbed the Thousand Mountains. There are only many mountains, but they are not high, and the highest main peak is only more than 700 meters above sea level. With the footsteps of Ma Han and others, half a day's work, it is easy to go up and down. At noon, we come to a waterfall.

This waterfall is high and steep, and the water is turbulent, and at a glance, it looks like a ladder standing obliquely. There is a huge stone at the mouth of the waterfall, the waterfall is divided into two streams, two jade dragon-like water columns fall from the sky, rush to the deep valley, splash up a few zhang high flying waves, the sound is like thunder, the water vapor is filled like fog, the scene is magnificent.

Ma Han was on the top of a mountain peak a few hundred meters away from the waterfall, standing on the rocks and looking at it from afar, and the left and right sides were on guard from miles away. Ma Han seems to be looking at the scenery in a trance, but in fact, he is really "out of his mind", not watching the waterfall.

Ma Han came here, of course, not to enjoy the mountains and rivers, he didn't have so much time, and he didn't have such a good interest. He was just looking for a quiet, quiet place to meditate, to recall something—some information, to be exact, about steelmaking and forging.

With Ma Han's background in his previous life, and the path he took later, it was originally incompatible with the eight-pole of steelmaking and forging. He wouldn't have had that information, but let's not forget that he had a robotic arm...... After installing the robotic arm, Ma Han had a few weeks of adaptation in the test center, and of course he wanted to learn more about the special alloy of his robotic arm, so the doctor threw him a thick book of "The History of World Steel Development".

It is related to the source, structure, and performance of the limbs that will accompany you all your life, no matter how big the horse is, you can only pinch your nose and look at it.

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

Ma Han was anxious to understand the modern parts related to his robotic arm. The previous ancient part is basically swept aside, and he only looks at some interesting records twice, so he really doesn't have much to write down. But the technical problems he is facing now are part of this vague impression, and it is really a book that I hate when I use it!

Therefore, Ma Han planned to find a quiet place, reminisce and sort it out in detail, and see if there is anything to learn from. The effort was not in vain. So far, he has really thought of some things, such as the steel filling method and the Suzhou steel method.

According to the development of iron control technology, the steel frying method is followed by the steel filling method. After that, there is the more advanced and convenient Sugang method. But these outlines are easy to remember, but where can you remember the specific content? How to fill steel? How do Sugang Su? Ren can't even think of it if he wants to break his head, who made him not distracted when he first watched it. But. It wasn't for nothing, at least he remembered some interesting examples of ancient swords-forging and forging deeds, and perhaps experienced craftsmen could be instructive of this.

Ma Han was pondering. Behind him, there was a report from the servant: "My lord, the horse worker officer has something to ask to see." ”

Ma Jun? Well, this person's mind is full of all kinds of machinery, and he can't see people, and he came to ask for it, most of which is the one who has eyebrows.

How long has it been, and how fast has it been? Ma Hanwei was slightly surprised and immediately summoned him.

Three years have passed, and the thin boy is already a seven-foot-tall, gentle and generous young man. Under the conscious guidance and strong support of Ma Han, the first inventor and craftsman of the Three Kingdoms, he entered the road of study, invention and creation faster than the original history, so as to achieve greater achievements. In history, Ma Jun, it was precisely because of the indifference of the general Cao Shuang to technology at that time that many of his important inventions had empty ideas, but they were ultimately not realized, including the improvement of the most famous profit and loss crossbow, which is suffocating.

Although Ma Jun spoke much more fluently, he didn't say polite words, and after he saw Ma Han, he directly presented a picture. Ma Han unfolded it and saw that it was a water drain, that is, a hydraulic blower structure diagram.

The water raft designed by Ma Jun is a huge wooden wheel erected on the shore of the turbulent water, which is driven by the impact of the water flow to rotate, and then the transmission mechanism drives the rotation of the row, so as to blow the powerful wind into the blast furnace. This hydraulic blower includes three parts: power mechanism, transmission mechanism and working mechanism, which are quite complete and mature.

Ma Han was pleasantly surprised, this Ma Jun actually has such a fast creative thinking, which is really amazing!

Ma Jun saw the joy on Ma Han's face, and while laughing, he also said the truth: "In fact, Jun is also suspected of cheating, this water conservancy wind wheel overturned, Bi Yilang (that is, Bi Lan of the Eastern Han Dynasty) has already invented, but it is too coarse, Jun has long intended to improve, and he has been thinking and meditating for more than a day...... "After that, he offered an original picture."

Ma Han suddenly, no wonder, only one day and night to design such a perfect pattern, it turned out that there was already an idea in this regard. When I took the original picture presented by Ma Jun, I couldn't help but widen my eyes, this, isn't this the most common keel waterwheel in the farmland in later generations, could it be that it was invented by Ma Jun?

In fact, it is true that the keel waterwheel, which has been passed down in the world for nearly 2,000 years, is one of Ma Jun's important inventions and has been the most important facility for agricultural irrigation in ancient times.

Because Ma Han had become the largest landowner in Liaodong and owned thousands of hectares of fertile land, he generously rewarded the soldiers who had made meritorious contributions to the battle with a lot of land. Ma Jun was meritorious in building crossbows, and he also got 100 acres of Zhongtian.

Due to the inherent land nature of the ancients, these days, Ma Jun has been running in the fields a lot, and he is very concerned about the problem of unfavorable irrigation of farmland. As the so-called need to give birth to invention, Ma Jun's vital interests made Ma Jun invent the keel waterwheel earlier than the original history.

Ma Han has been so busy kicking the back of his head that he hasn't had time to inspect his own land, so he hasn't noticed that there is no such important agricultural facility in this era. Build me a thousand such waterwheels, and I want the entire land of Liaodong to be all over here! ”

Ma Jun's heart was surging, and he felt like a confidant, and he was so excited that he stuttered again, and he couldn't hold back a word for a long time.

Just when the mood was right, an alarming voice came:

"There are assassins!"

"Fence up and catch these assassins!"

Assassin?! Ma Jun and the others were shocked. Hurriedly put the horse ring in the center. But Ma Han laughed, and quickly untied the pouch of the bow (the instrument that holds the bow), and took the bow in his hand. After the reversal of Liaodong, it is not surprising that some people are dissatisfied or hold grudges and take risks, and it is not surprising that they are those who are not afraid of death.

Ma Han pushed away his servant and strode towards the source of the sound. The crowd hurriedly guarded the left and right and opened the way ahead. Soon. Right in front of the waterfall, they spotted the Assassins surrounded by dozens of followers.

There were three Assassins, all of them in their twenties and thirties, dressed in short-shirted garments with their feet tied. The muscles of the exposed arms are very strong. The three Assassins faced the wolf riders in a circle back to back, and all of their weapons were ring-headed knives, and one of them was a strong man in his thirties, carrying a leather knife bag. There were three knives stuck in it, plus the one he was holding, for a total of four knives - was this guy an assassin or a knife seller?

When the horse arrived. Just as I saw the two wolf riders taking the lead, they stabbed at the assassin with four knives on his back.

The assassin raised his eyebrows, held the hilt of the knife with both hands, and waved it left and right, and when he made two sounds, the sword halberd of the wolf rider was actually cut alive. The two wolf riders were startled and retreated, but the Assassins did not pursue. The rest of the wolf riders wanted to attack, but when they saw this, they also froze.

Ma Han sighed lightly, since he went to the arsenal to inspect the weapons, he paid special attention to the equipment of his subordinates, these weapons were issued by him after personal inspection, and the ring head knife and short halberd in each person's hand reached at least eighteen refinements, which was higher than the equipment level of the national soldiers of Dahan County, and the equipment of the Beijing division soldiers.

Such a weapon was actually broken by a single blow? Well, the eighteen refinements are not very good, it's not that they can't be broken, but the problem is that the ring-headed knife in the opponent's hand was undamaged after cutting off the halberd, which is surprising.

At this moment, another wolf rider with a short axe attacked one of the assassins, and the blade of the axe in his hand collided with the opponent's ring-headed knife continuously, and after each side took a few steps back, the ring-headed knife was unharmed, but the axe blade was like a jagged tooth.

The weapons of these assassins were so sharp!

The lord was on the side, but he couldn't attack repeatedly, and the wolf riders and servants all felt that they were losing face, and someone shouted: "Take the bait!" ”

Several wolf riders quickly removed a strangely shaped shield from the saddle. This shield is roughly the same as a normal infantry shield, except that in the core part is a small circle of iron sheets, with a thorn protruding in the middle to push and kill, and an iron hook extending from the top and bottom to block the opponent's weapons.

This is a unique weapon of the Han Dynasty, called hook inlay. The infantry uses a combination of hook inlay and ring-headed knives, which can be used to restrain long-pole weapons such as halberds. However, when the weapon "halberd" was eliminated on the battlefield in later generations, it was also withdrawn from the battlefield as a targeted restraint weapon hook. But at this time, hook inlay this weapon is still very useful.

The wolf riders did not use hooks to hook the opponent's sword, in fact, they could not hook it, and when they saw the sharpness of the opponent's weapon, they wanted to use this iron shield to block. As a result, as soon as several wolf riders with hooks approached the assassin, the three of them slashed out together, and all the hooks and thorns on the hooks were cut off, and the strong man with four knives on his back even split the hooks and shields in half with a single sword, almost cutting the wolf rider's arm with the hook......

At this moment, the wolf riders and servants had no temper anymore, and shouted one after another: "I can't take care of it, let go of the arrows!" Shoot the arrows! ”

The wolf riders wanted to catch them alive, so they rounded them up closely, but they didn't expect the assassin's sword to be too powerful, so they had to release the arrows, hoping not to shoot them all to death, just leave one alive.

The three assassins' faces were miserable in an instant, and the strong man with four knives on his back was even more long knives hanging to the ground, looking up to the sky and sighing: "I didn't expect that I, Pu Yuan, came to Liaodong just to find pure water in the world, and I was unjustly killed as an assassin, and my corpse was in a foreign land, sad!" ”

Pu Yuan?!

Ma Han was full of excitement and blurted out: "Stop!" (To be continued......)
