In the early morning, the mist by the Kunming pool is shaking, and the water waves are vast, quiet and charming.

And the muffled sound of a landslide shook the ground as if even the earth was trembling, and the war horse under its crotch neighed even more "Herod", and uneasily stepped on its hooves and spun in circles, and its nose kept sneezing, looking very anxious and afraid.

Lu Dongzan was also frightened, and when he heard Fang Jun say that he was showing him something new, he was puzzled.

When Fang Jun rode towards the row of houses by the lake, Lu Dongzan saw a black smoke rising from the heavy houses rising into the air, gradually diffusing and covering the sky.

What exactly is the sound?

How can it be so huge!

Lu Dongzan couldn't suppress the curiosity in his heart, and hurriedly rode his horse to keep up with Fang Jun's figure.

This row of houses is built on the lake, all of them are simple and tall houses, no wood, no green bricks, smooth walls with clear water, Lu Dongzan knows that this is a house made of cement, although it looks simple, but it is stronger and stronger than the houses with green bricks and wooden beams.

There were guards guarding the door, and a fence was erected, Fang Jun got close, took out a token and showed it, and the guards pushed open the fence to reject the horse and let him in. With Fang Jun's identity still being so tight, it can be seen that the security level here is ridiculously high.

The group rode in.

Rows of houses are lined up in a neat row, clearly with the utmost care. The Praetorian guards have three steps and one post, five steps and one sentry, that is, they don't even want to mix in a fly.

Lu Dongzan was more frightened as he walked forward, what kind of place was this, and why was it so well guarded?

Thinking about the sound of the earth shaking the mountains just now, Lu Dongzan faintly felt that something was wrong......

It's just that he didn't have time to think about it, because he had already followed Fang Jun to a large open space.

Lu Dongzan's eyes were instantly attracted by the strange thing in the clearing, and for no other reason than this thing, it was a trace of smoke coming out of it......

It's actually a bit inappropriate to say that it's a strange shape, that thing is round and long, on an iron shelf, and the end is slightly raised, which is a very regular shape, but what this thing is, the well-informed Lu Dongzan doesn't know it at all.

Two soldiers in vests were holding a long brush and sticking into the thing, rubbing something vigorously, and Lu Dongzan was confused.

A military general with a helmet and armor greeted him, knelt down on one knee in front of Fang Junma, and saluted, and said respectfully: "The last general didn't know that Fang Fu Yin was coming, and he didn't welcome him from afar, so please forgive me." ”

"It doesn't matter." Fang Jun responded casually, threw the stirrup off the saddle and jumped off the horse, shook the whip in his hand behind him casually, and asked, "How is the test firing?" ”

Only then did the military general get up and did not reply, but glanced at Lu Dongzan. He knew the rest of the people, they were all Fang Jun's most loyal generals, but this bearded fan...... How did it end up here?

You must know that this is now the most rigorous place in the Tang Dynasty, and the slightest situation related to the development and manufacturing of artillery can be detected by the outside world.

And Fang Jun, as the initiator who single-handedly created the artillery, has the right to enter and exit freely......

Fang Jun saw his gaze, smiled, and said: "This is the great minister of Tubo, Your Majesty asked a certain foreign friend to see the great power of the Tang Dynasty, so that the great minister of Tubo can spread it to the plateau, and promote the good-neighborliness and friendship between the Tang Dynasty and Tubo for generations, you don't have to care." ”

"Whoa!"

The military general responded, anyway, you are the supreme person in charge here, so it's naturally okay for you to say so.

Then he said: "All kinds of data are in the test log, and everything is under control at the moment, even better than expected." It's just that the funds are a little stretched......"

Fang Jun nodded and raised his hand to interrupt his words.

Naturally, he knew why there was a shortage of funds.

What's the hardest part of casting a cannon? Not technology, not range, not power, but the material of the barrel. For any era, the material of the artillery barrel represented the highest level of metallurgical technology of the time.

The explosion of gunpowder in the barrel of the cannon, propelling the shell to fire, is too demanding for the barrel material. Although Datang's metallurgical technology is gradually improving, it is still far from reaching the level of later generations, although the sediment of the gun chamber will be cleaned after each launch, but after three or five consecutive shots, the material of the cannon chamber will not be able to withstand the powerful explosion and potholes and even deformation.

This barrel is considered useless......

The forging of a cannon barrel, not to mention the brass and iron materials required, requires countless skilled craftsmen and months of continuous polishing in the complicated process alone. It can be said that now this artillery research institute is a Pixiu who eats money......

Fortunately, Fang Jun had already ordered the artillery craftsmen in Huating Town to set off as a whole, and the entire relocation came to Chang'an and settled on the bank of the Kunming pool.

There is no way, after His Majesty Li Er saw the power of artillery, although he did not eliminate the technology like a certain holy lord and did not allow the development from now on, he also knew that once such a powerful weapon leaked out of the manufacturing method, if it was not done, the world would be in chaos......

Only by controlling it under his own nose can His Majesty Li Er sleep peacefully.

Seeing that the soldiers had cleaned up the barrels, Fang Jun glanced at Lu Dongzan, who had come behind him, and said to the general: "Try firing again." ”

"Whoa!"

The general answered, turned and walked past the artillery, picked up a small red flag, held it high, and gave a series of orders.

Charging, loading, adjusting the shooting angle, rows of wooden targets were erected in the distance, the distance was about 20 zhang, and there were more than a person high, all of which were humanoid targets made of solid thick wood.

"Ready!"

"Launch!"

The fuse was ignited, and after a while, there was another earth-shattering muffled sound, and the barrel of the cannon visibly spewed flames, and the scattered bullets filled in the barrel spewed out, and the wooden target twenty feet away was instantly scattered with sawdust and was shot to pieces.

Lu Dongzan's face turned pale.

This time the distance was closer, and the earth-shattering power of this long cylinder could be felt even more, and the moment it was launched, even the ground under his feet trembled slightly, and his eardrums were buzzing. But all this was not as shocking as the scene in front of him!

What a power that is!

With a bang, the wooden targets twenty zhang away were all shattered, and everything within the range of Fang Yuanzhang Xu was shrouded, and nothing was missed. Lu Dongzan can almost imagine that if this thing is put on the battlefield, when the Tubo warriors charge, this thing will be placed at the head of the city, not more, as long as ten or twenty gates, the flames will spit out the roar of the thunder god, no matter how brave and brave the three armies of the world are, they will not be able to withstand this blow, and there is simply no escape!

He knew that Datang's firearms were hugely powerful, but the legendary earth-shattering thunder in the past was far inferior to this new weapon!

Datang now has mastered this kind of big killing weapon...... How can this battle be fought?

Lu Dongzan's eyes were bulging, and his face was dull.

It's a shame that he still shouts that if Datang refuses to accept peace, then he will not hesitate to launch a full-scale war.

If you wait until the army is in the city, this weapon will be fired at the top of the city......

Lu Dongzan was covered in cold sweat, sweating like pulp.

Fang Jun patted Lu Dongzan's thin shoulder affectionately, and said with a smile: "Great Minister, how powerful is this weapon?" I wonder if if the Tibetan iron cavalry charges, will it be able to resist this power of destroying the world and destroying the world? ”

Lu Dongzan was shocked and said with a wry smile: "Erlang, good means!" Yesterday, the contemptible people were ashamed, but today they were taught a lesson by Erlang...... I knew that Datang had a second-class divine weapon, how could I dare to say anything? It's just a summer worm, and I can't do it. ”

Fortunately, Fang Jun showed such sharp weapons in front of him early, if he waited until the war in Tibet to start before getting it......

Hey?

Something is strange!

Since Lu Dongzan was praised as the "No. 1 Wise Man in Tibet", his mind was naturally superior, and in the blink of an eye, he woke up from the shock of the artillery and realized that something was wrong.
