[armor breaking crossbow: a crossbow machine made of hardwood, steel, animal tendon and other raw materials. It has good range and armor breaking ability. It needs supporting armor breaking arrows when in use. Attack speed: slow, weight: heavy, armor breaking + 1, range + 1]

Su Lun looked at the Heavy Crossbow and nodded with satisfaction. Although there are still many shortcomings, it can be used in actual combat.

"How much does this crossbow cost?" sullen asked, putting down the crossbow.

A craftsman with calloused hands nearby quickly took over the crossbow machine and said, "Lord, with the cost of labor and materials, the cost of such a crossbow machine is 30 jinnars. If it is mass produced, the price will be slightly lower."

The crossbow machine is not just a crossbow. The later maintenance and maintenance also cost a lot of money. The consumption of a crossbow is much higher than that of a bow and arrow.

"Make 3000 crossbows first." Su Lun thought about it and decided. The cost of 3000 crossbows is 90000 jinnars. If there are supporting arrows in later maintenance, these crossbows need at least more than 100000 jinnars.

"Yes, I'll let the workers prepare!"

"The production is carried out in this way during production." Su Lun took out a piece of paper and said that the paper says the assembly line production method. This method is not only fast, but also not easy to leak secrets, and the production difficulty is reduced.

The training of crossbow soldiers has already started. The crossbow soldiers in the north town are equipped with iron armor and a long sword without shield and other protective equipment. In the training of crossbow soldiers, they were not expected to rely on the long sword to fight. They were equipped with the long sword just in case.

Crossbow soldiers are led by Cecil, a human general just discovered by sulun. Their main training is array and crossbow operation.

Cecil is not a hero. At best, he can only be regarded as an elite leader, but he still has the possibility of advanced heroes. At present, the number of troops in Zhenbei city has exceeded 10000, and the total population and the number of troops have reached an amazing 10:1, which is also relatively small on the mainland.

Fortunately, the north town is still rich and can provide support. Having a harvest altar also makes the north town not short of food.

......

The northern wilderness.

The LOTAS mountain range is like a creeping dragon across the northern wasteland. It starts from the southwest and extends to the northeast, with a total length of about 800 Li. It is precisely because the existence of this mountain range blocks the cold wind from the large ice field, so that the wasteland in Zhenbei city will not be too cold in winter.

In the vast area south of the LOTAS mountains, many tribes live here. The north town occupies an area in the southwest of the LOTAS mountains.

At this time, in a wasteland far away from here, the weather has been very cold. The snowflakes are scattered in the air. Messy tents can be seen everywhere. Cooking smoke rises around the tent. This is an orc tribe. However, it is strange that there are some jackals and trolls in the tribe in addition to orcs.

These jackals and trolls do not exist as slaves. They look more like equal cooperation.

"Bang!"

A loud noise came from the tent, followed by the roar of orcs.

"That land must belong to the Stormrage clan."

"The blood blade jackals will not give up their deserved booty! That is the promised land given to us by our Lord yanogu!"

"Come on, the promised land of shit. If you want to seize it, just say it. Don't make so many excuses." a tall Troll sneered.

"If you dare to blaspheme my Lord, I will kill you and sacrifice to my Lord!" roared the Jackal.

"Come on, I won't blow your dog's head!"

The scene in the tent was hot. It seemed that a fire fight would happen the next second. The orc, the high jackal and the troll stared at each other without giving in, but tried their best to restrain.

"All right, put out the fire!"

"What is the purpose of our gathering here? Everyone must know," said an old Orc shaman in the corner.

If Suellen will recognize it again, the orc Shaman is the big shaman of the orc tribe he defeated. After the ORC was defeated, sulun killed the orc chief, but the orc shaman disappeared. You know, there were centaurs chasing the orc, but he still retreated.

The old Orc's skin is shriveled like bark. "If humans stand firm on the wasteland, they will slowly expand around according to their inertia. If we can't pull out that nail as soon as possible, there will be no living space for us in the northern wasteland in a short time. I'm not alarmist! Cough..." the old Orc coughed violently, The thin and dry body gives people a feeling that it will break at any time.

Hearing the old Shaman's words, the orcs, jackals and trolls did not refute. At the beginning, the strength of the fire blade tribe was no weaker than them, but after a decisive battle, the fire blade tribe disappeared, leaving only the old shaman to join the angry wind clan with the remaining orcs.

"And the troll tribe was killed by him along with the ancestral spirit. Now we haven't even defeated those humans. Don't you think it's too early to divide up the combat power?"

"The first thing we need to solve now is to defeat mankind. As for the booty, cough... We will distribute the booty according to the contribution in this battle." the old shaman finished his words in one breath, as if he had exhausted his energy and sat aside and stopped talking.

"OK, just distribute it according to the old Shaman's method." the orc troll and the Jackal looked at each other and nodded in agreement.

......

Sulun didn't know that the fish that had escaped the net was now tangled with the three tribes of orcs, jackals and trolls to start a war. He is now listening to the report of the little demon.

The little demon's figure is concave and convex and very petite. After coming in, he sat directly on Su Lun's thigh and began to report the output of the underground world during this period.

"This month, 103 Jin of gold, 1526 Jin of silver, 11 tons of iron ore, 23 gemstones and 37 grams of secret silver are produced..."

"How much spider silk is produced?" the little demon's hip elasticity is very good, which makes Su Lun some weak fire, and reaches out to hold the little demon in place.

"Fifty six strands of spider silk have been produced this month and have been handed over to Hathaway. Hey, take it easy and don't tear my silk stockings. This is the last one of this month."

"I'm watching." Su Lun's hand movements are very skilled. The little demon is wearing a dress similar to a slim dress today, which vividly outlines the curve of his body.

Su Lun, who has trained his marksmanship to the master level, has long been willing to follow his heart. Their cooperation is like concave convex inlay and fits perfectly.

......

"You move! Move!"

"No, I'm numb all over!"

Half an hour later, when the battle was over, Chris was paralyzed like a beautiful snake. Suellen let her rest here and got up to tidy up the scattered documents.

"Take it easy, this silk stockings are scrapped again!" the little demon who slowed down said angrily looking at the broken silk stockings.

"The spider silk production will increase next month. Give you more points," Suellen said with a smile.

"Hum, that's about the same." the little demon snorted.

Suellen is funny to himself. I won't tear you away if I give you more points.

After the construction of the main body of the wizard tower is completed, since Hathaway, Karina, Alex and grace start to build the interior of the wizard tower, the wizard tower needs to lay a large number of energy channels to transfer the energy in the element pool to each position of the wizard tower, which requires a large number of magic crystals.

The magic crystal produced by the Crystal Beast in the secret realm needs to be supplied to the wizard tower first for a long time, and the element pool needs to be built in the wizard tower. This is the energy source of the wizard tower. For example, the large wizard tower built in Zhenbei city can not be supplied by the general element pool.

The size of the element pool is divided by the amount of energy stored in it. The lowest standard element pool contains 100000 degrees of energy after it is filled with element water. The Wizards set the energy consumed by casting a one ring magic arcane missile to one degree.

The 100000 degree element pool can display the energy of 100000 Arcane Missiles. This element pool is generally equipped with a small wizard tower. The 100000 degree element pool can not drive the wizard tower to fly. Even the ultimate weapon of the wizard tower, the magic energy pulse railgun can only be launched once, and it also needs energy storage.

This 100000 degree element pool, let alone sulun, even Hathaway is unwilling to install it on the wizard tower. The wizard tower is completely designed and built according to the standards of legendary wizards, and even upgraded to a floating tower to reserve space. Therefore, the element pool to be built by Hathaway is a large element pool.

The energy standard is more than one million. At present, the upper limit of this large element pool is five million degrees. No matter how large the element pool is built, it is not cost-effective. The construction of the element pool requires the use of magic gems, secret silver, magic steel, arcane dust, star dust and many other magic materials.

The larger the element pool is built, the more materials are needed. When it exceeds one million, it increases geometrically. In fact, the materials needed to build an element pool that can hold five million degrees can easily build five one million degree element pools, and there is still surplus.

So basically, no one will spend a lot of materials and energy to build a 5 million degree element pool. Generally, a 2 million degree element pool is enough, unless you want to build a floating city, but even a super large element pool with 5 million degrees of energy still can't make a medium-sized city fly.

The most cost-effective is the 2 million degree element pool, which Hathaway is going to build. The location of the element pool is at the bottom of the wizard tower. There are three floors underground of the wizard tower, covering an area of 3000 square meters. All this floor is built with obsidian, and it is strong enough with hardening.
