What's the matter, he doesn't even let him sleep peacefully, how can there be a problem with a good production? Hu Menglin turned over lazily and got up slowly, and suddenly his head "buzzed": It's a group of craftsmen who are experimenting with the bronze cannon, what if there is a good one?

Thinking of this, he was completely sleepy, got up in a hurry, and was about to run out, but was dragged by Hua Qingyun, who had already woken up, "Get dressed!"

By the time Hu Menglin came out, it was already close to noon. Everyone is recognized that Hu Menglin is in good health, so no one deliberately remembers what time he got up, anyway, Hu Menglin didn't run in the morning, he must have drunk too much, or he was tired at night!

The orcs of the Qinglin tribe made fun of Hu Menglin on the one hand, and envied his physical strength on the other.

Hu Menglin saw that the Qingtie Patriarch was standing under the tree far away, and when he saw Hu Menglin come out, "Hu Menglin, I got a bronze cannon just now, but as soon as I tried it, it exploded on the spot, and several strong people of the Bronze Tree Clan blew up their legs, let's take a look!"

As soon as Hu Menglin heard that no one was killed, he immediately calmed down a lot, "Save people first! Stop the others first, except for bows and arrows, cannons also stop, don't try again!"

The two of them ran to the underground "hospital", where more than a dozen Snow Lotus Clan powerhouses from the Thunder Snow Mountain in Northern Xinjiang were busy with surgery, and it seemed that these Bronze Tree Clan powerhouses were seriously injured. Hu Menglin couldn't help for a while, so he had to ask about the cause of the incident.

It turned out that after Hu Menglin left last night, everyone chatted for a while, and as a result, the excited ethnic groups simply started working overnight. There were the most bronze coins, and as a result, everyone fused, plated in the gold cannon, and according to the pattern provided by Hu Menglin, the transformation was completed, and everyone checked it again and again, and the result was exactly the same as the pattern provided by Hu Menglin.

When everyone rushed to make a bronze cannonball, they began to experiment. The Bronze Tree Man, with great faith, was not aware of the danger of this object at all, and was very close. As a result, after the cannonball was sent into the barrel, there was nothing wrong, but when the wind elemental messenger activated the wind system magic circle, only a loud noise was heard, and the closest ones were all blown away, and although the wind elemental messenger was the closest, he was also blown away, but he was an elemental body, so he was unharmed.

Hu Menglin lowered his head and thought, the formation should be fine, this is what the old staff spirit has been thinking about for a long time to improve! Theoretically speaking, Hu Menglin also thinks that it is completely feasible! What is the problem with that? Could it be that the bronze and gold essence cannot be plated together?

No, according to the theory on Earth, the metal melted together would not cause an explosion at all! Suddenly, he realized what the problem was!

"Patriarch Qingtie, have you been here, have you been here? Are those bronzes evenly plated, that is to say, the thickness is the same?"

Qingtie Patriarch's face also changed, "I didn't pay attention, anyway, those bumps and bumps are right, and the size is not bad!, I guess there is also a problem with the thickness, although these wind element channels are the same width and narrow, but there is a difference in height and height, so the speed is different, causing blockage, so it exploded!"

The two of them hurriedly looked at it, and saw that those Bronze Tree Clan powerhouses had awakened, and they were quite optimistic. After all, they are a tree clan and can recover naturally. And now, with the source of life provided by the Qinglin tribe, plus the operation to connect the severed limb, it is estimated that it can be restored to its original state in ten days.

Hu Menglin and the others then returned to the scene of the gold cannon. Several Qingtie clan powerhouses were looking at the fragments left at the scene. I found a few large fragments, and sure enough, I found that the inner wall was uneven and the thickness was obviously not consistent. The remaining two Bronze Tree Clan powerhouses who had learned their lesson immediately completed the new "Pure Gold Plated Bronze Cannon" in one day again according to Hu Menglin's wishes. After the depiction of the cannonball was completed, Hu Menglin used his mental power to gently feel the connection between the lines between the cannonball and the barrel, and felt the thick friction between each other.

After closing his eyes for an hour, Hu Menglin completed all the tests, he shook his head and said, "There are more than a hundred problems in total, some have slight differences in the width of the line, some are obviously squeezed in thickness, some are not smooth enough, and the sense of blockage is obvious when rubbing!"

Hu Menglin shook his head and said, "It's not that it can't be done, it's that our craftsmanship is too rough, on the one hand, it is more meticulous when the magic circle is formed, and the time is a little longer, three or even five days." On the other hand, after molding, it is necessary to perceive it with mental power and constantly revise it. As he spoke, he instructed the two Bronze Tree Clan powerhouses to correct them little by little. In the blink of an eye, it was already getting dark, and the four of them went back to rest. At the end of the day, it's only a tenth of the revision!

According to this calculation, if you count the shells, it will take about fifteen days for a qualified "pure gold and copper-plated cannon". While eating dinner, Hu Menglin pondered the question of the bronze cannon. Sitting at the table was Hua Qingyun. She silently listened to Hu Menglin's question, and suddenly smiled,

For example, some people make gold cannon barrels, some people finish shells, some people complete copper plating, some people are responsible for molding, some people are responsible for modification, some people are responsible for testing, and so on, doesn't this reduce time?"

Hu Menglin slapped his thigh, isn't it, why does he always circle around these special races! Perhaps, someone will solve the problem of uneven inner walls without much effort!

Thinking of this, he didn't care about not finishing his meal, and ran out to find the Qinglin patriarch. Listening to Hu Menglin's idea, Qing Lin smiled, "Hu Menglin, in fact, I wanted to tell you a long time ago, don't be too tired yourself! These things, you can ask questions, and it should be other people who really do the work! For example, the material problem, I think it is more appropriate to use iron branches to fuse to cast cannons, the gold essence is too hard, and the quantity is too limited." As for the smoothness and smoothing of the inner walls, I have already chosen one!"

Hu Menglin was stunned, how could he not know which clan still had this ability?

Qinglin looked up at the sky, "I told you earlier about the guardians of historical civilization, but now there are two other clans that you haven't seen, one is the guardian of the sea civilization of the sea clan, although they were born, they have little to do with you, so they didn't take the initiative to see you."

As for the Guardians of the Mineral Civilization, they live in the Nanban tribe. I'm talking about the polishers, they're the ones I don't know, but I know that there is a family of people who specialize in repairing the smallest minerals and metals. If you're interested, go for yourself. Not only invite them, but also settle the grievances between the Coiled Snake, the Luoshui Alliance, and the Southern Barbarian Orcs by the way!"

Hu Menglin nodded and said, "For the last reason, I should go! By the way, can you be sure that the clan can handle these small problems? If you can, I will let those Bronze Tree Clan powerhouses hurry up and get one and try the power of the magic circle!"

The two chatted for a while, and Hu Menglin began to recruit the powerhouses of the Bronze Tree Clan overnight, along with the gold element and water element messengers, around the magic circle inside, constantly improving and modifying. It took three days for the water elemental messenger to finally determine that the thickness, width, and narrowness of each place were basically the same.

A shell shell is filled with ordinary silver worm feces and sealed. The group carried the cannon to the dinosaur forest and found a hidden place. After seeing that everyone had retreated, the Wind Elemental Envoy gently infused the Wind Elemental power, only to hear a loud bang, and the cannonball rushed into the sky, far into the sky.

Everyone didn't care about the cannon barrels on the ground, and all of them flew into the sky at once, and in the open space five thousand meters away, the shell had already exploded into the sky, the crater was very small, and the surrounding trees were basically not much damaged, so it seemed that the power was not great.

Hu Menglin fell, picked up the shells around him, and a dinosaur winged man who was hiding far away from the branch flew over, "This little bird is too fragile, it plunged into the ground at once, and its body suddenly cracked, and then there was a puff of smoke, and it died with a small cry!"

Hu Menglin looked at the smoke marks on the ground that were obviously left by the burning of silver worm dung, and smiled bitterly, "It seems that artillery shells are also a problem." These silver vermicomotive dung were obviously burned out before the bronze bullet casings hit the ground before they could explode!" There were various expressions on the faces of the dozens of people around, some were disapproving, some were smiling bitterly, and some were full of confidence!

Everyone returned to the place where the cannon barrel was located and checked the cannon barrel, the bronze inside was obviously less layered, and the thickness had changed, now everyone was dumbfounded, this problem is far more difficult to solve than the power of the cannonball explosion!

Hu Menglin also proposed that it is possible to completely use the iron tree to fuse other plants or mineral metals, or to fuse the gold and silver coins produced by the cash cow with other metals for trial production, and as for the problem of uneven thickness, we should wait for a period of time to study and solve it, and first test which metals are suitable for making cannon barrels! At the same time, we should organize personnel to study the power of artillery shells and the shells of pottery, iron, and stone shells.

To this end, Hu Menglin set up three groups, a group led by the Golden Element Messenger, a group led by the Bronze Tree Clan powerhouse, and a group led by the Lower Riba Patriarch Xia Di Wuxian led a group to study cannonballs and bronze guns.

At this point, Hu Menglin handed over the bronze cannon to others, and the improvement of the bow and arrow was handed over to the patriarch of Qingtieshu and others. Hu Menglin proposed that not only a strong bow, but also a short bow suitable for the use of the elves, but also bows and arrows used by other races. Materials should not be limited to iron trees, bronze, mythril, branches, bones, bamboo, etc. can be considered for mixed use.

The Moon Elves and Flower Elves, the Centaurs, and the Porcupine Men were arranged to be some of them as assistants. At the same time, Hu Menglin also put forward requirements for arrow tips and arrow shafts, on the one hand, it is necessary to use various existing resources, such as bee stings, tree tips, bone spurs, etc., and at the same time, it can also be ground with bones and stones.
