Ansen was very good at observing words and expressions, saw the distress in long Bufan''s heart, and solemnly said, "Lord, this Yuanjing vein is of great value. Money is another aspect, but the most important thing about this Yuanjing vein is that it can be used in war, that is, the legendary Yuanjing gun."


    "Yuanjing cannon!" long Bufan''s eyes lit up. He once read this knowledge in the Sihai Pavilion of lingxuanwu mansion. The birth of Yuanjing cannon is a turning point of alchemy in the sky continent. This Yuanjing cannon is definitely a very terrible attack force during the war.


    For example, compared with the top-level Yuanjing gun, it consumes a lot of Yuanjing stone, and this gun will continue. The power may be equivalent to a high-level Rune attack array. In a crowded battlefield, it can kill hundreds of people at once. During the war, as long as ten large yuan crystal guns are mounted, as long as several guns are fired continuously


    The enemy can kill and injure tens of thousands in the blink of an eye, which changes the war too much.


    But Yuanjing cannon is a "crystal swallowing beast". It''s terrible to consume this Yuanjing stone. Many countries and zongmen have limited resources. They simply can''t afford high consumption weapons such as Yuanjing guns on the battlefield.


    Because this Yuanjing gun consumes all Yuanjing stone. It is much more precious than Yuanyang stone!


    "A low amount of Yuan spar may be exchanged through martial arts scripts or treasure vessels." Anson analyzed: "but a large number of Yuan spar, whether empire or sect, are not allowed to be sold outside. Although there is smuggling, how many can be smuggled?"


    Long Bufan nodded. Will you exchange a lot of military materials? However, it is not difficult to buy Yuanjing cannon. People who pay a high price for several alchemies can make it by themselves.


    "If you have this vein of Yuanjing ore and cooperate with Yuanjing cannon... Storm territory is not afraid of being coveted by other forces, at least a little more security." long Bufan began to have a plan. If you produce hundreds of large Yuanjing cannon, as long as you have enough Yuanjing, it will be as powerful as a missile.


    "Alas, it''s a pity that he only knows the structure of guns." long Bufan sighed inexplicably in his heart.


    "Lord, what are we going to do now?"


    The cold light twinkled in long Bufan''s eyes: "at present, what we need to do is to consolidate and strengthen the urban defense force, and find a way to get the drawings of refining Yuanjing cannon! Then, we can mine the Yuanjing vein tightly and quietly."


    In the Lord''s residence, he now has quintuplets in the refining Pavilion. Their professional level from the sect is much better than that of the scattered cultivation outside.


    "Yes," Anson said solemnly.


    At the bottom of his heart, long Bufan has made up his mind. He can''t shrink back anyway. He must face the difficulties without fear.


    Soon, around the spar vein, a large number of crazy soldiers were sent to dig the spar mine. At the same time, there were wolf cavalry of the crazy war tribe around. Externally, they just claim to have found metal veins.


    On the other hand, long Bufan did not forget to fulfill his promise, that is, to give the crazy soldiers a safe house.


    First of all, longbufan let people push down the old city wall and expand the area of the town. Long Bufan can save a lot of money from the labor cost. He has transferred 500 crazy soldiers from the ore vein. The naturally powerful crazy soldiers are the best manpower.


    The enthusiasm of crazy soldiers is enough to melt a glacier. Almost from the beginning, they have been digging day and night, building carvings and tired earth into Guo, building bricks and tiles of the city wall.
