The expansion of the refinery is urgent, it takes time, even if the purchase order for the equipment has been issued, but the production and transportation of the equipment takes time.

If all goes well, the refinery expansion will take at least three months to complete the initial construction and equipment installation and commissioning, and at that time it will only be a small estimate of the trial production, and an additional commissioning time will be required to reach the design capacity.

Before this, a large amount of oil extracted from Well No. 5 could only be stored first, or simply actively reduced production.

After dealing with loans and several orders for equipment purchases with relatively large amounts, Lin Ziran basically did not interfere much in the affairs of other Tsingshan Petroleum Company.

However, the major matters have been dealt with, and there is not much left in the headquarters of Tsingshan Petroleum Company, because the three subordinate branches are all independently operated and managed, the oil field is the oil field, the oil refinery is the oil refinery, the commercial bank is the commercial bank, and even the finances of the three are independently accounted for.

In this case, in fact, there are not many affairs at the headquarters of Tsingshan Petroleum Company.

Lin Ziran spent more time still on the training of the troops, tossing his Qingshan Patrol Battalion every day.

It's a simple and monotonous life, but it's full of hope.

The training of the Qingshan Patrol Battalion has gradually become regular, especially the first company, which was the earliest to become an army and has the highest overall quality of its soldiers.

Sometimes when watching the first company conduct exercises and training, Lin Ziran would have an illusion, as if he had seen the troops on Earth before and after World War I.

The reason why it is said to be an illusion, rather than a real idea, is because although the first company is very similar to the infantry units on the earth with rear-loading guns in many cases of marching and even fighting, the difference is still very large, for example, when the first company is fighting, it never lies down and shoots.

Because you can't reload it at all!

However, if you conduct a defensive operation after the fortifications, or if you plan to use ambush tactics on the battlefield, then it will look decent.

I just don't know what the effect of this new type of light infantry tactic developed by Wu Guanlin is in actual combat!

And soon Lin Ziran had a chance to verify!

At the beginning of February, the military order of the Third Division arrived in Qingshan Town again, this time the military order was to let Lin Ziran lead people to escort a batch of supplies north, and also said that this time the transportation of materials was very important, so that he must ensure safety along the way.

For this kind of task, Lin Ziran is very familiar.

In the past six months, the Qingshan Patrol Battalion has escorted more than a dozen times of supplies, as short as seven or eight days, and as long as ten days and a half months, there will be a task of escorting materials.

From the first month of this year to the present, it has only been more than a month, but the Qingshan Patrol Battalion has escorted three batches of materials to the north, but these three escorts of materials have not been transported to Chongguang City like the two at the end of last year, but the materials have been transported to the middle of the road as in the early days, and then the troops sent by Jian Liangzhi will respond.

At the end of last year, the two consecutive escort supplies were attacked by the Guang'an rebels, and the losses were not small, which made the Third Division completely disappointed with the militia groups of the Qingshan Patrol Battalion, and even if the troops were tight, they still did not dare to let the militia take the risk of escorting.

It doesn't matter if the militia dies, it's the loss of materials that matters.

In this way, Lin Ziran is naturally easy to save, anyway, he didn't take less money, thousands of Hengyuan every month for military expenses and supplies such as ordnance and ammunition, although he was owed a lot at the beginning, but he could still get more than half.

It is naturally a good thing that you can still get so many benefits without doing much, and that it will not affect the training of the troops because of a long combat mission.

At first, Lin Ziran thought that it was a regular material escort, but he didn't expect that although this time it was still a material escort, the materials escorted were different.

When Lin Ziran saw the huge team of materials outside Qingshan Town, he was stunned.

This time, the materials they escorted were nothing special, nothing more than guns, ammunition and food, but this amount was really a lot!

In the past, there were dozens of trucks, no more than a hundred, and most of them were some consumable materials, mainly food and ammunition.

But how big is the convoy he sees now?

There are more than 100 horse-drawn carriages for transporting artillery shells alone, and these are all four-wheeled heavy carriages used by the military, and the carrying capacity is generally about one ton.

This means that there are more than a hundred tons of shells alone!

Lin Ziran personally stepped forward to take a look, and all of them were large-caliber shells, and there was not a single shell with a diameter of more than 80 millimeters, 100 millimeters, or 115 millimeters used in the common five-jin, seven-jin, and nine-jin field guns.

All of them were medium- and large-caliber shells with a heavy cannon of more than 14 catties, and he even saw many shells of 48 catties or even hundreds of catties.

These shells are not at all shells used in the field artillery of ordinary army units, but shells from large-caliber siege artillery!

In addition to shells, he saw quite a few heavy artillery!

There are more than 10 14-kilogram heavy artillery guns that are preferred to be used by the main long-range heavy artillery units of many contemporary feudal towns, and this kind of 14-kilogram heavy artillery usually fires 132 mm round shells, and the effective range can reach more than 1,500 meters, and the maximum firing range can reach more than 6,000 meters.

But this is nothing, he also saw several mortars of twenty-four or even forty-eight pounds!

However, what surprised him the most was that he also saw a real giant, it was a short-barreled mortar, the caliber was 300 millimeters in size, although it was a short-barreled mortar, but it was extremely heavy, the main gate gun was placed on a huge transport carriage composed of multiple sets of wheels, and dozens of horses pulled this cannon slowly.

Seeing so many heavy artillery and heavy artillery shells, Lin Ziran's first reaction was that the senior generals of Luo An's army had gone crazy.

They actually transported these heavy artillery to the front line through this area of Qingshan Town, which is not crazy.

You must know that Qingshan Town is not the only transportation route to the front line of Chongguang City, it is only one of them, and because the terrain is more complicated, it is destined to be more troublesome to transport, so there are very few materials transported, and they are all ordinary materials.

The Luo An army transported its baggage to the front line, and more often it was transported through Sanyang Town, that is, along the Luo River to the north, even if some sections of the river were blocked, but most of the time it would go north by land along the coast.

Especially such a thing as heavy artillery, such a heavy thing does not go to the river, but runs to Qingshan Town, which is not crazy.

You must know that the road from Qingshan Town to Chongguangcheng is not very easy to walk, and there are many uphill and downhill slopes.

But soon, Lin Ziran knew why.
