"I guess it was the first two attacks that made the orcs angry. Satin began.

Luo Heng also probably knows the status of the various races in the orcs, although the superior race is strong, but the fertility is very low, and the lower race is low, but the fertility is very strong, this is like a litter of rats a month, a litter of seven or eight, and then two or three months of sexual maturity, can breed again, and what about tigers, lions, it is good to be able to give birth to one in a few years.

Orcs with the same strength eat more, after all, a strong physique does not appear out of thin air, even if the bloodline is high, it must have enough nutritional support, why some giants can play basketball, and some are unstable on their feet, this is the reason.

Luo Heng looked at the dense army of orcs, the strength of the orcs Luo Heng has also seen it, and the human side is fortunately well-armed

But as a soldier, Luo Heng knows that war is always changing, and Luo Heng doesn't know what the high-end combat power of this world is like.

Just like Herman, the commander of the entire fortress, it seems that he is just stronger, just like those knights, and he has not burst out with much powerful and changeable power.

And the rock giant in the orcs, the bear man holding a wooden shield of more than two meters and a half and a thick palm, is not easy to provoke at first glance.

There is no doubt that the big ones have a huge advantage when fighting with cold weapons.

"Cheney, are you worried?" Seeing the anxiety in Luo Heng's eyes, Satin asked.

"Yes, teacher. Luo Heng nodded

Sardin patted Luo Heng on the shoulder: "Don't worry, the Northern Fortress is the largest fortress of mankind." ”

Luo Heng nodded: "Teacher, I always feel a little uneasy. ”

"It's okay, you go and take a good rest, you can do more throwing, the orcs won't do their best to attack this time, they're not that stupid. Satin did not believe that the orcs could breach the fortress, which had not been breached since it was built. There are still some things that Sardinia has not said, and he really can't hold it, so he will give up the first layer of the fortress, and the orc tribes will retreat as long as they grab enough food.

However, the fortress also consumes the strength of the orcs, and it is really impossible to hold on to such a situation, otherwise it is easy to let it out, and the orcs are afraid that they will come here every year.

Of course Luo Heng didn't know this, Luo Heng couldn't sleep, Luo Heng was still asleep a few days ago, Luo Heng was thinking about a lot of things in his heart, mainly the things in front of him.

"The weakness of artillery is also obvious, but it is not very realistic to make too complex weapons, and what is the power of throwing * now, it remains to be verified, attacking the target and attacking the enemy are completely different things. Luo Heng muttered in his heart

And the concept of human warfare is applied to these orcs, it will not work, the width of the city wall is limited, if the width is wider, then the safe distance of the artillery can be expanded.

"But without stone walls and city walls, then artillery can't play much role, tens of thousands of orcs charge together, unless?" Luo Heng thought of a*, and it was very powerful, and the principle was relatively simple.

Thermobaric bombs, but thermobaric bombs have a wide range of attacks and are used for defensive operations, whether they are suitable or not, Luo Heng doesn't know.

"But there's definitely going to be magic material involved. Luo Heng was a little eager to try it in his heart, with magic materials*, he might get unexpected results.

In a daze, Luo Heng finally fell asleep, in his sleep, Luo Heng dreamed that the orcs were dense, like a tide rushing towards the fortress, those orcs jumped onto the city wall with a jump, and the rock giant threw huge stones, smashing the trebuchet to pieces.

Luo Heng, on the other hand, saw that the artillery on his side could not stop the enemy's attack at all, and suddenly, an orc priestess waved the mallet in her hand and smashed it into herself.

Whew!

Luo Heng sat up all of a sudden, and with the help of the faint flame of forging and the sound of clanging, Luo Heng finally came to his senses.

Luo Heng's sweat, I don't know what time it is, I got up and came to the side to wash my face and sober up.

There is a sewage drainage system in this fortress, as well as a water source system, and I don't know where it is discharged.

After beating the metal block for a while, Luo Heng's heart calmed down, casting and throwing*, the people of the artillery did not rest, but took turns to operate, and the technical difficulties involved were all made by dwarves, and the rest would be handed over to humans.

Out of the forging area, Luo Heng suddenly felt cold, and there was a thick fog outside, and he couldn't see anything inside the white fog.

Luo Heng's heart tightened even more, Luo Heng didn't know what was going on in his heart, he didn't have any other thoughts in his mind when he started fighting, and now that he had fought, he had mixed thoughts.

The orcs did not attack, Luo Heng supervised the forging of artillery, as well as the throwing *, the throwing * has been improved, and the throwing * has a handle on it, which is convenient for shaking hands, because when the pineapple is caught, the fingers are forced to throw it as far as the handle.

"Fire is a magic crystal, flammable, high temperature, and generally uses combustion additives. Luo Heng carefully looked at the properties of the magic materials.

Luo Heng tried to find some powerful weapons from these materials, but he didn't have a clue.

When he was eating in the morning, Luo Heng saw the pieces of meat in the wooden basin, and a flash of inspiration flashed.

Holding the wooden basin, Luo Heng came to the kitchen, and the two dwarf aunts were in charge of the food of the entire dwarf, and these two dwarf aunts were also Satin's maids, yes, not Madame.

"Aunt Sheena, is there any demonic beast grease?" Luo Heng thought of something that was powerful, but definitely not complicated to make,*.

* It is a sharp weapon for street fighting, unless some top-notch Tan~K, general armored vehicles or something, when encountering this*, only the bombed have no power to resist.

And these orcs have thick hair on them, and Luo Heng feels that they are more suitable for this * combat needs.

"Yes, it's all here. Hina also held the wooden basin to eat meat and bread, and took Luo Heng to the back of the kitchen.

Inside a stone pool, there is melted monster fat, and I don't know what the physical characteristics of this thing are, and further tests are needed.

However, the experiment needs some tools, some tools that can be used for refining experiments, what about these tools?

"Magic Merchant. Luo Heng wanted to build it himself, but he felt that it was impossible, so he thought of the magic merchant.

After eating and drinking, Luo Heng came outside, the magicians live in the magic area, and no one else is allowed to enter there, just like the dwarven forging area, only some high-ranking officers and dwarves can enter and exit, and the rest can only enter and not exit, at least this is the case during the war.
