"Sir, I'm coming. Ruan Ling opened her mouth and said, Lan Yunxi hesitated, she didn't fight with Ruan Ling, she is the big leader of Liuyun, she is good at grabbing things, it is more troublesome to buy things, and when she arrives at other people's territory, she may still be angry and dangerous.

Ruan Ling is different, before she joined the Shengong Temple, she was one of the members of the merchants formed by Rainforest City, and she was very experienced in doing business.

In order to get enough silk, Renault gave Ruan Ling a lot of rights, in addition to transferring all ten hot air balloons to her, he also gave her two hundred black-haired flying horses, and the materials in the convoy, as long as she put it forward, Renault's side was unconditionally satisfied.

Ruan Ling Ke understood much better than Renault, she brought 10,000 gold coins and five boxes of life-saving pills, which were enough to exchange for fifteen tons of silk, if it were not limited by transportation capacity, the wealth in Renault's fleet could buy more silk than imagined.

With Ruan Ling leaving with Mo Qiang, there was no grandmaster in charge, and Renault was not at ease.

After Ruan Ling started, Renault began to take stock of the team's harvest these days, Zhang Tan worked very hard, and the musket increased by fifty, hearing this data, Renault shook his head, the production efficiency is too low, the number of barrels is a lot, but the spring has not been able to increase the output, on average, there are only two qualified springs a day, it seems that Renault must personally take action.

The increased number of muskets made Renault fire, but the research of artillery was gratifying. In less than a month, Zhang Tan not only completed the design, research and development, test launch experiment, and finalization, but also completed the process flow, just waiting for Renault to make a decision, and it can be directly mass-produced.

In fact, what Renault wanted was not a real artillery, but more like an enlarged version of the gun, which fired not a solid iron ball, nor a relatively advanced flowering bullet.

The artillery that Renault wants, as long as it can shoot scattered bullets, even the range requirements are very low, the minimum is 100 steps, if it can reach 200 steps, it would be better.

After trying ten cannons in a row, Renault was quite satisfied, and the artillery independently researched by Zhang Tan could penetrate a single layer of leather armor within one hundred and fifty steps, and such a lethality was enough. The barrel is filled with scattered bullets, and in each scattered bullet, there is a specially made triangular iron thorn, which is much more lethal than the iron sand, anyway, this kind of iron spur, as long as there is a model, it is good to cast it directly, and there is no requirement for strength and quality.

In a scattershot, there are a full hundred such iron spikes, with a total weight of three catties and two taels, mixed in seven and a half catties of gunpowder, the effect is very good, and within the effective range, a herd of cattle can be brought down.

There are two problems with this kind of artillery that cannot be solved, one is that the rate of fire is very slow, the first cannon has nothing to say, you can prepare in advance, starting from the second gun, you need to clean the chamber with clean water, by the way to lower the temperature, and then wipe it with a dry cloth, fill the fixed shells mixed with iron thorns, and finally it must be compacted and the gunpowder can be fired.

The second problem is the material of the barrel, although it will not blow up the chamber, but seven and a half pounds of black powder, when fired, a lot of heat is generated, the heat dissipation speed of the barrel is much slower than the launch speed, after firing ten cannons in a row, you must stop and wait for the cooling, otherwise you don't need to ignite the fuse, the newly loaded ammunition will explode by itself.

The problem of the cannon barrel, Renault didn't have a good solution, the former one reminded him of a piece of history: "Zhang Tan, you tried to make a batch of sub-barrels." ”

As he spoke, he took a piece of paper and drew it, the sub-barrel is a bit like a cannon shell, make a sub-barrel that is slightly thinner than the barrel, pre-load the ammunition in it, and when fighting, directly stuff the sub-barrel into the gun chamber. After launching, tick out the subtube and just change it to continue launching.

A cannon can be equipped with three to five subbarrels, which increases the firing speed by a factor of five to ten.

Zhang Tan understood as soon as he heard it, this method is good, and it is not difficult.

In fact, Renault has a good solution in his head, but due to the limitations of Da Chu's materials and production capacity, he can only use the most stupid solution.

In addition to artillery, grenades, Zhang Tan did not ask for instructions, and directly began to produce, due to the lack of materials, he did not dare to make more, only made 5,000.

When the convoy came out of Dingjun City, it was fully loaded, not only food and cloth, but also iron, Renault had many requirements, how much iron could the convoy carry? Now there was not much left, and Zhang Tan tried his best to produce muskets and springs, consumables such as grenades, and it was already the limit to prepare 5,000 pieces.

In the blink of an eye, the convoy walked in the rainforest for more than two months, and in two more months, it was possible to reach the forbidden place of death chosen by Renault.

In the past two months, Renault has been extremely nostalgic for the seven days of driving a hot air balloon, in the dark rainforest, after a long time, the whole person is about to collapse, and Renault is a little unbearable.

In order to solve everyone's psychological problems, the people of the team took turns to ride the black hair, and took a few laps in the sky to relieve their depressed mood.

The good news is naturally there, Ruan Ling finally brought back fifteen tons of silk after forty days, listening to her ease, Renault learned from Bai Qiang that this business was very thrilling.

With the money that can buy fifteen tons of silk, there are many people with red eyes, Ruan Ling is in Shunde Mansion, fighting wits and courage with major trading houses, if it weren't for Bai Qiang's desperate protection, she would have died dozens of times.

Although there are not many grandmasters in Great Chu, there are still big cities like Shunde Mansion. Those who can afford to do silk business are all big merchants, and it is impossible to support the grandmaster, so there is no problem at all to ask the grandmaster to take a shot.

It wasn't until they found out that Ruan Ling also had a grandmaster by his side that they had to give up the use of force and dispel the idea of taking it by force.

Ruan Ling's trip took ten days longer than Renault expected, not only because the driver was not skilled enough to operate, and there was no command from Song Zhe, but also because Ruan Ling tried to avoid the sight of others as much as possible, until the business was over, few people had ever seen a hot air balloon.

This made Renault quite satisfied, the strategic-level equipment of the hot air balloon will let people know sooner or later, and now there is not even a camp in the Shengong Palace, so naturally the later it is exposed, the better.

This is also in the Nanzhang area, which is full of rainforests, and you can't see the sun when you look up, plus the land is vast and sparsely populated, as long as the landing site is far away from Shunde Mansion, it is really barely possible. If it is in the inland of Dachu, even if it is only flying at night, it is extremely difficult to avoid being discovered.

After two and a half months of arduous rainforest trails, we finally reached our destination, a land that looked desolate.

In the Nanzhang area, it is quite difficult to find a place without rainforest, but this wasteland of nearly 100,000 square kilometers, no one dares to live, here is close to the rainforest on one side, on the other hand, by the forbidden land of death that the people of Nanzhang talk about, and on the other side by the sea.

It is said that this is a place cursed by death, and no matter which toast moves here, it will not be long before the whole clan will die, without exception. As for all kinds of creepy beast roars at night, throwing a few people from time to time can only be regarded as a trivial matter.

This is just the periphery of the Forbidden Land of Death, beyond this desolate red earth, there is an extremely wide range of mountains, and there, is the real Forbidden Land of Death.

No one knows what's inside the mountains, and it's not difficult to walk through this desolate place alive, but very few can survive overnight when they enter the mountains. Occasionally, someone who escaped alive was either silent or frightened.

Renaud can be said to be the only person in this world who knows what the Forbidden Land of Death is like, originally he thought that it was just a mountain range, until he walked here and activated the microorganisms, he really saw the scene in the Forbidden Land of Death.

The Forbidden Land of the Reaper is a large volcano or crater, the diameter of the crater mouth is more than 800 kilometers, the depth is not bottomless, and the surrounding accumulation of rocks forms the Death Mountain Range, measured from the most edge of both sides, with a diameter of more than 1,500 kilometers.

Not to mention the Reaper Mountains, just in this desolate place that the convoy has just set foot on, there is an underground world with an area larger than the surface, and this underground world is the largest underground world that the God of Wealth has scanned so far, and there is no one.

Even if Renault had already walked on the land at this time and had stimulated the microbes to the maximum, the God of Wealth still couldn't scan the whole picture of the underground world.

At this time, Renault looked calm, but the corners of his mouth kept twitching, this is a treasure land.

Why are there no rainforest plants in this 100,000 square kilometers of land?

The reason is simple, this is a mining area, right at the foot of Renault, stepping on a rich iron ore with an average iron content of 70 percent, so to speak, the team is walking on a huge iron ingot.

In addition to iron ore, dozens of metal minerals were found at a depth of 300 meters scanned by the God of Wealth, among which there were as many as 16 new unidentified metal ores, all of which were not found on the earth.

In the underground world, there are not only more kinds of metal minerals, but also a large number and variety of biota, and the God of Wealth is still frantically scanning and analyzing, and before he gets the scan analysis report, Renault doesn't know what these creatures rely on to form a biological chain.

There are more minerals in the underworld, which means that plants cannot grow either, and without plants, where do these animals come from?

The convoy did not go deep into the desolate land, but along the junction of the desolate land and the rainforest, towards the sea, and the camp selected by Renault should not only be close to the sea and the rainforest, but also have enough water.

There is no shortage of water in the rainforest, but there are no rivers nearby, and it is absolutely impossible to form a human settlement without rivers and lakes.

If there is no ground world, it does not mean that there is no underground world, the world of Dachu is a world with very rich water resources, and the technology is not developed, so the damage to the natural world is very small.

Everyone had already smelled the fishy sea breeze, and Renault finally gave the order to stop advancing, this is it, a very magical place.

This place, on the surface, is not suitable for building a city at all, and no leader will choose here, but this is the most suitable place to build a city on the periphery of the forbidden land of death.
