Tang mansion.


    The casting drawings of the artillery had been submitted, and Tang Hao pounded the car for installing the barrel all day.


    It''s a gun, but in fact it''s just an enlarged version of a sudden fire gun. It''s impossible to manufacture precision instruments like those in later generations in this era.


    The measurement method, iron smelting technology and irrigation can''t keep up.


    The so-called shells are just hollow iron seeds, wrapped with explosives and stones.


    At present, there is no explosive device with such accurate calculation. Only the long lead can be ignited by itself when the shell hits the ground.


    Changsun Wuji''s residence was completely busy. In the new workshop, everyone was busy with the innovation of weapons.


    The weapons to be replaced in the whole Tang Dynasty can be piled up into a hill, which is enough for these blacksmiths to be busy for a year and a half.


    Pounding the manufactured shells in his hand, Tang Hao studied the vehicles equipped with guns.


    "Grandpa, there is news coming up to the hall. The West Turks are moving."


    Wu Tong''s face had a touch of calm from the experience in the military camp, and there was no wave on his calm face.


    Tang Hao picked up the corners of his mouth, smiled faintly and fiddled with the wooden wheel hub.


    Looking at the creaking wooden wheel, Tang Hao slowly stood up and patted the dust on his hands.


    "He who should come always comes."


    "Let''s go! Take three shells and let''s go into the palace."


    Wu Tong has also seen the newly developed shells, but they have never been lit.


    This time, I was excited to hear that Tang Hao was going to transport this to the imperial city.


    I can finally witness the power of this thing!


    Excitedly, he chucked a shell with a big bowl mouth and excitedly followed Tang Hao into the carriage.


    Shaking all the way, Wu Tong looked very careful. He didn''t put down the ball. He was afraid that it would cause a great change.


    Especially in the densely populated Chang''an imperial city.


    Before entering the Tai Chi hall, I heard the quarrel in the hall.


    "Why is it difficult to attack cities and seize land? Is it difficult that the Tang Dynasty did not attack cities and towns?"


    "General Su''s military life is no worse than the minister in the court in terms of his experience! It''s just to capture a Turk!"


    "You''re right! Tang Hao must have some tricks, but can''t we leave Tang Hao and can''t March and fight?"


    The noise came from the hall. Tang Hao had a headache for the king of Tang.


    Although Datang is full of talents, it sounds like the whole head is going to explode.


    Striding into the hall, many old ministers immediately smothered and pushed the old minister who shouted for victory in front of them, nuzui toward the door of the hall.


    Gradually, the noise subsided, and most people noticed Tang Hao''s uninvited visit.


    Ignoring these questions, Tang Hao went straight to the palace. He bowed to the king of Tang sitting high.


    "Your majesty!"


    "Hearing about the western expedition against Turks, I came here to present a treasure."


    treasure?


    As soon as the voice fell, the hearts and gods in the temple were shocked.


    Since entering the capital, Tang Hao has made many inventions.


    The same tea can be made into delicious fried tea by Tang Hao''s hand. This wine is unique, mellow and long, with endless aftertaste.


    And the rouge, gouache and clear glass. Isn''t that amazing?


    Now there are treasures to attack cities and land?


    The king of Tang, sitting on the Dragon seat, flashed a light in his eyes, leaned forward slightly, and looked at Tang Hao''s empty handed way in a circle.


    "What treasure is it?"


    "Present it, let me have a look!"


    Tang Hao replied with a smile.


    "Your Majesty, these treasures are extremely powerful. They can crack mountains and earth, and break bricks and stones."


    "This hall is definitely not a place to observe."


    The whole audience was in an uproar as soon as this remark was made.


    Yuchi Jingde rushed out of the crowd, pulled Tang Hao and said.


    "OK! Your boy has really made artifacts that destroy the sky and the earth?"


    "Duke Wei, didn''t you lie to us?"


    Tang Hao didn''t know what had been discussed in the hall just now, but his original purpose was to use the shell as explosive.


    At least it can help the siege army win the city quickly and clear the obstacles.


    Tang Hao didn''t think much about who he would eventually send. After all, he had nothing else to ask for.


    Changsun Wuji is very excited. If there are such instruments in the world, the territory of Datang will be stable!


    Not to mention this small Turkic barbarian, even if the neighboring countries join hands, what''s the fear?


    Stepping out of the crowd, looking at Tang Hao with a plain face, he asked.


    "Really?"


    "Good nephew, tell me quickly, where are we going to observe?"


    Glancing around, Tang Hao smiled mysteriously.


    "This powerful treasure can only be ignited and observed in the wild mountains."


    "We should also send some imperial forest warriors to block the whole site to prevent accidental injury."


    After that, Tang Hao smiled easily and said.


    "Now the treasure is outside the palace. The minister also remembered that there were many people in the hall, so he didn''t dare to offer it himself."


    "I hope your majesty moves to the southern suburbs and is watching!"


    Tang Hao''s exaggeration was just to add some mystery. It''s just getting people''s attention.


    Seeing this, some ministers did not wait and urged the king of Tang to observe.


    The king of Tang Dynasty was also curious about the treasure. He couldn''t stand the novelty of the old ministers and waved his hand.


    "Move to the southern suburbs!"
