At that time, the headquarters of the instrument institute has been set up in the Youzhou Horse Farm, Zhang He's Tiger Guards are stationed around, which shows Liu Yi's attention to these two institutions, after he ascended the throne, the Instrument Bureau was hung under the Ministry of Industry but still has a high degree of independence, and now in addition to the capital, the research institute in the Youzhou Academy is still preserved, and most of the production units are still set up on the empty flat land of the racecourse, but at this time, the Qinglong Battalion of Liaohua who is responsible for guarding them has been replaced.

"Third-rate, meet General Zhang!" The black-clothed man in the wheelchair clenched his hands into fists and bowed deeply, his legs were not conducive to such a salute It was already a great respect for Zhang He, as for the black veil to cover his face, it was by no means rude, he experienced a fire when he was a teenager, and his face was burned quite horribly, so he was afraid of being rude, after all, he was also a serious seven-grade official of the Han Dynasty.

"Hehe, why did our Dao military division quickly pass on the military order to order a certain soldier not to move, I think it was the third division that brought something new to help our army break through, there is no need to be polite and come quickly, I am still burning here." Zhang He took a step forward and held his hands weakly, with a smile on his face, and his mouth was also extremely polite, originally the status of a craftsman in the late Han Dynasty was not high, not to mention the respect of such a heavy general as Zhang He, in addition to the excellent plan of the third-rate itself, it was also the result of Liu Yi's example.

A strong empire needs all kinds of outstanding talents as a foundation, which has long been unswerving in Liu Yi's heart, and it is also reflected in his practice as always, the Appliance Bureau is now the authentic official institution of the imperial court, and those skilled craftsmen in it enjoy high treatment, and more importantly, their social status has also been greatly improved.

Sky Bombardment, Cloud Piercing Arrow, Iron Armor Army, Flying Tiger Water Division! The equipment is used to reflect their value with a huge military contribution, and of course, a large part of it is manifested in agriculture, and Liu Yi can have such manpower and material resources in the war, and they have made great contributions! And the generals of the unified army also personally felt the great help brought by this department in the war, and Zhang He's Tiger Guard Army can be said to be the most deeply felt among all the main forces of the Han army.

One of the biggest contributors to the capture of Anxian County was the bombardment cannon, and the infantry artillery coordination tactics derived from it became a sharp weapon for the Han army to attack the city and pull out the village, and the three heroes in the south have suffered from it. Wei Yanqi's attack on Micang Mountain made the battle of Hanzhong in one fell swoop, and it was a benefit to the wheelbarrow developed by the equipment to transport military materials through mountains and rivers, the inventor of this wheelbarrow is precisely the third rate, and he also contributed enough strength to the consolidation of the first strong army of the Tiger Guard, how could Zhang He, as the main general, not know?

"General Zhang praised it falsely, how dare Liu be this division in front of the military division and the general? The villain is favored by the Son of Heaven is difficult to repay in case, the weather has been very cold since the beginning of winter in Hanzhong, and he suddenly felt the things mentioned in the previous time His Majesty and the Bureau, and then it was tested repeatedly in Hanzhong City that it was quite feasible, so he said to the military advisor that everything had to be discussed with the general in detail! The third rate hurriedly thanked him when he heard this, and his gratitude when he mentioned Liu Yi should be beyond words!

The third rate of the surname of the third person, was originally a family of craftsmen in the state, and then in the troubled world, he was the only one who was lucky to get rid of the fire, but also ruined a pair of legs, feet and face, his heart is firm and perseverance is extraordinary, and Liu Yi moved to Youzhou after pacifying the state, and the family craftsmanship has not been wasted! However, the disability of his body and the destruction of his face made him taste the sweets and hardships of the world, and it can be said that entering the apparatus was a major turning point in his life, and the Yang Shan he led can be described as his discerning Bole. At that time, he said that General Liu was very popular, as long as he had unique skills, he would never judge people by his appearance and family background.

The third rate is grateful to Yang Shan for being a teacher, and he is even more grateful to Liu Yi, and what he has seen and heard after joining the equipment institute makes him firmly believe that Yang Shan's words are not false, here they only need to bury their heads in their own profession to seek a breakthrough, General Liu will provide them with all the conditions they need, and they will not miss any of their efforts with clear rewards and punishments, and it is undoubtedly a happy thing to have such a thing for their sake everywhere! And the apparatus is different from any previous guild, General Liu's example has led to a very moving change of opinion on them, that is a real equality and respect, how can the third rate who feels such an atmosphere not go all out?

There are geniuses in various industries, Hua Tuozhi and medicine, Wang Xinran and medicine, Zhao Yunzhi and marksmanship, Gan Ning and water, and the third rate in his own field is also an out-and-out genius! Putting aside all his worries and burying himself in his career, he quickly achieved success, and he was credited with the design of the ox-drawn plough in Yandi, and the concerted efforts of his peers were also fully reflected in the apparatus, and it was under these conditions that the third class succeeded in developing a wheelbarrow in addition to the wheelbarrow.

It is precisely because of this that he was personally received by King Yan, you can imagine the excitement in the heart of the third rate at that time, but also with some apprehension, his face is really difficult to see, let alone a high-powered King Yan? Wouldn't it be rude to wear a veil? However, after seeing Liu Yi, these third-rate worries disappeared, King Yan was not only brave and brave in governing the army and loving the people like a son, but also had great respect for these craftsmen, seeing his bold smile, he didn't take his appearance seriously at all, and even more cordially held his hand to talk to him, and the reward was extremely rich! Just for King Yan's smile and approachable demeanor, the third rate is already a dead loyalty!

There are many craftsmen like the third rate in the utensils, and when it comes to Yan Wang, they have some feelings of introducing him as a confidant in addition to reverence, because no one can think that Yan Wang is also an expert before, he will often discuss with everyone to exchange the projects they are researching, and his words are also extremely incisive, often thought-provoking between just a few words. In this regard, the third rate understands it as Yan Wang is a naturally great character, and he naturally knows everything.

In the battle of Hanzhong, Cao's army was burned by Wei Yan's surprise attack, and Zhang Hu's counterattack was also launched, leaving Cao Cao with no chance to breathe. Liu Yi, who was in Yanzhou, also saw the development of the situation clearly, and the key to the battle situation in Hanzhong would be focused on the attack and defense of Xiongguan, and when the Han army's counteroffensive momentum soared, all parts of Beiping were already summoning craftsmen to go to Hanzhong to make more siege equipment for Zhang Hu's department, and the third rate followed.

Carpentry is a third-rate specialty, but he also has a deep knowledge of the way of casting, he is one of the few people who can talk to Xu Gang, the world's first master craftsman, and is no stranger to quenching, I remember that when today's son mentioned in a certain discussion, the conversion of extreme cold and heat will destroy the internal structure of the substance and make it softer, but the mastery of heat is the biggest problem. Originally, the third-rate considered this problem in order to improve the material of the Sky Cannon, but by chance, he remembered that this seems to be also used to break the level!

It can be called the natural danger of Xiongguan, in addition to the dangerous terrain, the hardness of the city wall is self-evident, if the strong city wall can be crushed, the biggest reliance of Xiongguan will no longer exist! The third rate didn't know why he thought of the battle array ahead, but once this thought arose, it couldn't be suppressed, if his idea could succeed, wouldn't it be a great help to the great cause of the Son of Heaven? Craftsmen like theirs don't let ideas stay in their minds, and they do what they think, so he and a helper immediately start experimenting in Hanzhong City, which is also the routine of the workshop.

Of course, the third class did not mention to outsiders what the purpose of his experiment was, but he was very pleased with the results, the hard bricks were greatly reduced in hardness after being transformed by extreme cold and depth, and sometimes they could be destroyed with a single punch from a strong man! This supports third-rate ideas to the greatest extent, and all that remains is how to transfer the results of the experiment to practice.

If there were no sophisticated equipment of the Han army, the third-rate whimsy would only stay on paper or in the mind in the end, but the many changes that Liu Yi brought to this era gave it a basis for implementation! Extreme heat can be made by launching thunderbolt canisters from the sky, with the continuous improvement of the refining accuracy of those fire oils, the thunderbolt canisters of the Han army have made great progress compared to the battle of Anxian back then, and the high temperature and duration of its burning will be more violent! And with the shooting accuracy of those top marksmen of the equipment battalion, the wide surface of the city wall is not a problem.

This is extremely hot, as for the extremely cold weather in the Han provides the greatest convenience, at this time the third rate heart swelled up with the feeling of God helping me, no, it is God helping the Son of Heaven, His Majesty is the real Son of Heaven, after asking the local old man and the military meteorological officer in detail, he is more sure of this, there will be heavy snow within half a month! Originally, this was a disadvantage for the military, but there are always exceptions to everything, and this has become good news in the ears of the third rate. In those days, the apprentices all knew that the master had poured a solid brick wall in the courtyard, and continued his experiments without sleep for days and nights, of course, the rules of the apparatus made them only obey orders and not make too many inquiries, and when they should know, the master would always do his best, they just knew that when the brick wall collapsed that day, the master's face was full of ecstatic smiles, and he repeatedly bowed to the east!

Liu Yi would not have thought of all this when he established the apparatus, and no one would be able to do this at all, perhaps it was the will of heaven in the dark.
