The Rolls-Royce had gone a few more kilometers when the road suddenly opened up, and the jungle on the left side of the road shrank inland, as if snow had met hot water, and everywhere the road could be seen, the land had been cleared. In the distance www.biquge.info a ditch runs through the middle of the Shinchi, then turns around at the end of the Shinchi towards the avenue, passes under the road, and plunges headlong into the sea.

This ditch was excavated by thousands of naturalized people mobilized by the Committee of Agriculture, and Sun Wenbin also called in a lot of prisoners from Yusha to participate in the excavation work. In fact, the biggest problem of this project is not the lack of manpower, but the lack of tools. At present, the monthly output of Dongfang Iron and Steel Plant also has a lot of steel, but the hardware factory has only begun to put into production, whether it is planning employees or metal processing equipment are still running-in, so the number of tools used for excavation is simply Sun Wenbin's nightmare. He could only send people to guard the hardware factory every day, holding the approval of the Planning Commission and waiting at the end of the production line, and pulling away as many farm tools as he came out.

The export of agricultural tools of the hardware factory is also an important sales channel, whether it is Anyun or the inland merchants of Annam have quickly discovered these excellent quality and quite affordable price of the "labor" brand Oriental Port agricultural tools, so the sales point of the Ministry of Trade is full of long queues every day, the merchants and hawkers have to wholesale a large number of hardware products here every day in exchange for agricultural products in the inland of Annam, and then these agricultural products will gather in this Oriental Port, at this time the Oriental Port has become a large town, The daily trading volume is astronomical in this time and space.

At this time, the project of the southern section of the ditch has been completed, but there is no water, and now Zhou Rui is very curious when he looks at the blue-gray ditch.

Zhou Rui didn't know, but Ren Xuefeng understood that this blue-gray color must be the new product of Dongfang Cement Plant-Portland cement, and the channel built with cement is not only stronger and more durable, but also able to play the role of a channel with more water flow and greater effect.

At this time, the construction of the northern section of the ditch was in full swing, and since the location of the ditch had been reserved for irrigation before the development of the farm, although thousands of naturalized people and captives were digging in the farm, it did not affect the crops of the farm in the slightest.

Thousands of people digging a ditch at the same time, this is basically impossible in this time and space, whether it is Wuguo or Annam, the land is privately owned. Moreover, these private lands are basically excavated from jungles or mountains, which are neither flat nor irregular, and often the land owned by them is intertwined because of the relationship of acquisition, often A's field is wrapped in B's field, and D's field is in A's waterway. Irrigation is often a matter of luck, and in order to compete for irrigation water, it is common for the owners of the fields to fight and fight, and it is no less than a fantasy to want them to build small water conservancy projects for the land close to others.

However, the land developed by the Senate was different, and in Sun Wenbin's plan, he would open up a 15,000-mu paddy field and 20,000 mu of dry land. At this time, he had excavated 6,000 acres of dry land from the jungle, and another 3,000 acres of paddy fields had been opened up, but because the water conservancy project had not yet been completed, it was not the time to sow rice, so the paddy fields were only sown with some leguminous plants at this time, which were sowing soybeans, soybeans, broad beans, peas, mung beans, lentils and other blocks.

Sun Wenbin and the staff of the Committee of Agriculture have inspected the soil in this area, which is somewhat different from the land of the old time and space, but still lacks nitrogen, and if you want to improve this soil, the rotation of leguminous plants is a pretty good solution. The roots of leguminous plants have nitrogen-fixing nodules, which are not only excellent green manure but also excellent feed crops.

Ren Xuefeng continued to drive the Rolls-Royce north, and after a short time, he reached a walled area on the right side of the road.

"What is this place?" Zhou Rui, who had never seen a wall along the way, questioned at this time. "It's a big place surrounded by this wall."

The height of the wall is four meters, and there is a trench one and a half meters deep five meters away from the wall, and on the other side of the trench is a two-meter-high barbed wire, and every thirty meters there is a four-meter-high watchtower, on which stands an army soldier in a light blue combat uniform. The soldier wore a light green braided belt with a canvas bullet pack that was bulging with bullets, but on each watchtower there was a small bullet box containing a hundred empty cartridges. It is used to drive away wild animals and pedestrians who are overly curious. This is the Senate's weapons test range.

At this time, I heard a loud explosion inside, and I saw a thick iron pipe flying and rolling in the air, and the smoke and dust from the explosion rose into the sky. Seeing that, Ren Xuefeng's heart couldn't help but twitch, this is obviously an artillery, the Senate has not been able to equip the artillery due to the steel material provided by the steel factory, and now it is only equipped with a low-bore pressure flying thunder cannon and a spring cannon fired from a super-caliber range. But what was flying in the sky just now must have been an artillery, and I don't know if the explosion just now caused casualties.

However, contrary to Ren Xuefeng's fears, the explosion of this gun did not cause casualties to the test firing personnel. Since the artillery test firing team left the firing position after loading, there were no casualties at all, and the explosion of the gun barrel was not a firing accident, but the military industry department was testing the life of the newly made artillery barrel.

"Okay," Lin Shenhe was watching the artillery with several veterans of the military industry department and members of the artillery test firing team at this time. "How many?"

The young female veteran who was in charge of recording on the side opened the record book, "Three hundred and sixty-three rounds, which is a record achieved in continuous firing without rest and cooling." ”

"Look," a veteran commanding several test-firing team soldiers pushed the gun to the ground and turned it over, "the crack that appeared before has now burst open, and it is the crack that caused the explosion." ”

"I think we can add a few hoops to the barrel, so that the inward pressure is applied to the expansion of the fire, which will reduce the chance of cracks and effectively increase the life of the barrel." Lin Shenhe participated in the casting of cannons in the United States in the old time and space, and he was far more experienced in the matter of making cannons than the group of military veterans in front of him who were born in China and only obtained theoretical knowledge in various documents and had absolutely no opportunity to cast cannons in person.

In fact, even the current artillery is not what Lin Shenhe wants, what he wants to build is a rear-loading rifled cannon. Now, although rifling is not a problem at all, the body barrel material does not allow the development of high-pressure rifled guns, and the reloading of the gun latch material requirements is even higher than the body barrel material. Therefore, at this time, Lin Shenhe was only facing a 100mm smoothbore gun, which could only fire round solid shells, shotguns, and grenades with practical timing fuses.

This cannon is a replica of the Napoleonic 12-pounder gun, which was the most photographed during the American Civil War, and it uses a 100 mm diameter shell. According to the captured Meideno naval guns, it can be seen that the Meideno naval artillery in this time and space has completed the unification of caliber, and they all use round cast iron shells with a diameter of 118 mm and a weight of about 5.46 kg. If you use 100 mm cast iron shells, although you can't use the shells fired by the opponent, your own shells can't be used by the opponent, and due to the small caliber and slightly lighter weight, the range of this gun under the same charge is more than that of the naval guns of the Medeno Navy. This was compared with a test firing of captured Meideno naval guns.

And the chamber pressure that these forged steels can withstand is also higher than that of the bronze naval guns on the Medeno battleship, so Lin Shenhe is still quite satisfied with this cannon now.

"Did you record the distance after the shot just now?"

"All of them have been recorded, three hundred and sixty-two rounds have been recorded, most of the shells fell within 1200 meters at an elevation angle of 10 degrees, a few reached 1700 meters, and the farthest reached 2135 meters." The female patriarch said as she flipped through the information.

"Okay," Lin Shenhe turned the cannon with his foot on the barrel, "Send this cannon back, and after checking it, send it back to the furnace, and let the test range find all those shells and return them to the furnace for recasting." ”

…………………………

"Comrade Ren Xuefeng," the elders on the side of the road were walking along the road, and Bao Bao was taking Newton to learn and operate the level on the side of the road at this time. Newton was recording the observed data on the record paper beside him, and Bao Bao was greeting Ren Xuefeng, who was driving.

Ren Xuefeng slowed down the speed of the car and stopped beside the bag. Zhou Rui looked curiously at the little child standing behind the strange tripod in front of him. Bao Bao is crossed by one person, this married patriarch has been interfered with by his father-in-law's family, has no children, at this time directly regarded Newton as his own child, since Newton left the purification camp has been taken by Bao Bao all day long.

At this time, Newton had been eating in the veterans' canteen for more than a month, and the nutrition that he had lacked for many years at this time had also made up a lot, not only did his body begin to look stronger, but his face also began to have meat. At this time, he was wearing a strange dress that was obviously relatively large, this was an old dress that Jiang Yan's son could not wear, these clothes brought by the old time and space were not only "novel in style and fine workmanship", but most importantly, these clothes were precious things that could not be copied now. Zhou Rui looked curiously at the cute bear on Newton's chest, he knew that it was a bear at a glance, but what kind of person can draw a bear so cute, especially when worn on a child's body, it makes people feel very cute, and makes Newton's whole person look very energetic.

"I received an order to report back to Dongfang Port, but I didn't say what it was, do you know?" Ren Xuefeng was very curious about the reason why he was transferred back all the way, and wiped his right hand under his lips, "Why don't you know, Dongfang Port has spread, there was an explosion in the steam engine yesterday, three naturalized people died, and Zhang Yuan was injured, and you were transferred back to analyze the cause of the accident." ”

"I'll go, Zhang Yuan is injured?" Ren Xuefeng was so surprised that he almost shouted.
