Large cities without their own will always be the pain of the entire race of the black elves. They have the strongest attacking army in the underground world, but they have no way to produce war equipment on their own. Even if they can grab some, they will soon be damaged due to the lack of craftsmen and places that can repair war equipment.

Obsidian City also attracted the fact that the black elves did not have the ability to create war equipment. When they retreated from Tsukuhe City, they took away all war equipment and destroyed the buildings that could produce war equipment, making the black elves unable to threaten Obsidian City.

However, there are many independent functional buildings scattered in the wild. Some are recruiting buildings that can recruit soldiers, and some can generate taxes and resources. Some war equipment factories can also be found in the wild.

But these are all primary buildings, and there is no way to advance or produce advanced weapons for troops.

After so many years of development in the lower caves of Obsidian City, Ingram of course controlled several war equipment factories in the wild, but these war equipment factories could only produce light crossbows, light stone throwing cars, and simple city ladders...

The range is short and the power is small, and it is far from reaching the attack power that can threaten the Obsidian City wall. You can only use a small section of the city wall regardless of losses to suppress it.

Ingram urgently needed heavy siege weapons, but this strategic weapon was simply impossible to buy from ordinary merchants. Purchasing from other places was not only expensive, but also during the plane war, everyone was desperately stocking up supplies for war. It didn't matter that there was no channel to buy such sensitive heavy weapons.

You should know that dozens of low-level soldiers can operate several artillery and heavy crossbows to prevent the ultimate creatures from approaching; the destructive power of several heavy catapults on the city wall is no less than that of the meteorite technique released by a high-level earth magician.

The function of war equipment is to allow low-level soldiers to exert the attack power of ultimate creatures and heroes.

Now a channel for purchasing heavy war equipment is placed in front of Ingram, and there are even more advanced alchemy equipment. With these heavy equipment, she can not place all hopes of attacking Obsidian City on snatching the city gate. Even if she can't grab the city gate, the black elves with enough heavy war equipment can fight a siege head-on.

Want! Want it all!

Ingram is like a gambler, and the best chance is right in front of her. In order to conquer Obsidian City, she must equip her army with the best and strongest weapons.

Even if these military purchases will ruin everything, as long as you can get Obsidian City, all your efforts will be rewarded a hundred times a thousand times.

"I need a list..." Ingram considered that his army had no experience in using heavy war equipment and did not know how to configure a wide variety of war equipment. So after she made up her mind to purchase it, she said to Daliang: "Your Excellency the Duke also needs to provide us with a reasonable purchase recommendation...

As long as the price you give is reasonable, I will never default on any payment.

As the Lord Duke said, we do not have enough gold coins, but we have resources, minerals, slaves,... population, all valuable things.

I only have one requirement, which is to allow my army to have the ability to bombard the long-range under the city with Obsidian City."

This time, Ingram took the initiative to stretch out his neck...

Daliang smiled and said, "Please rest assured about this... After I go back this time, I will personally prepare a list of heavy-duty ordnance purchases for the Mission Mother, and will also allocate an instructor group to guide how to use these war equipment. I can even simulate an Obsidian City siege battle step by step, and teach you how to effectively use these weapons on the battlefield... and obtain the maximum effect with the minimum loss.

With these heavy war equipment in Tuihe City, the city defense of Obsidian City is no longer a problem for you. I have no doubts about the ownership of Obsidian City.

Come, let's cheer for victory together! Cheers to the rise of the Black Elf by the Mother Ingram!"

The discomfort at the beginning of the banquet and the gap between the guest of honor were swept away at this moment.

Ingram stood up with all the Shadow Matriarchs, and they picked up the red wine that the blood-sucking maids poured for them, shouting the names of Obsidian City and Ingram.

Morale is like a rainbow!

Drink the red wine in the glass together, and the atmosphere at the banquet became lively.

After drinking a few more glasses of red wine, everyone felt a little drunk, and Daliang even talked to the Miss Ingram and the Shadow Matriarch with drunkenness.

He used magic on the wall to draw a structural diagram of the entire Obsidian City, and spoke like a general about his vision of attacking Obsidian City.

He marked one black elves' army after another to the periphery of Obsidian City, and at the same time indicated the attack route and strategic purpose of each army.

He feinted the attack on both sides, one on the main attack, and the other on the other for the Obsidian City defenders to escape.

Then subdivided it, there is a main attack point on the feint surface and a concentrated breakthrough point on the main attack surface. At the same time, according to the changes in the battle situation, the functions of each attack position are constantly changing.

In the war database of the University Alliance, there are a large number of battlefield simulation materials in various environments. The Alliance and the Northern Lord Alliance Command Center will organize command personnel at all levels to randomly select battlefield environments and conduct simulated war deductions every day.

Daliang only needs to find a battlefield deduction similar to Obsidian City's environment, and then explain it according to the interpretation, which is enough to scare these black elves who have never fought a siege.

Sure enough... Daliang once again attracted the attention of Ingram and the Shadow Matriarch.

If it is a wild encounter, every black elves present is a raid expert, but the siege battle has always been the weakness of the black elves army. There are no flying troops or siege equipment, and the black elves army has always avoided strong attacks on the city.

Ingram did not prepare too clever tactics for how to attack Obsidian City, especially when her army was about to be equipped with heavy war equipment on a large scale, she did not know how to effectively exert her military strength in the siege.

Now... a textbook siege tactic detailed explanation was placed before Ingram and her generals.

She and a group of Shadow Matriarchs looked at the tactical demonstration of the Obsidian City siege on the wall, and listened to Daliang's detailed explanation.

Sometimes I think about it, sometimes I suddenly realize it, sometimes I applaud and sometimes I applaud.

Everyone was impressed by Daliang.

In an instant... Miss Ingram actually felt like she had made a profit by signing an unequal treaty with Daliang.

How could such a powerful ally be obtained without the signing of that treaty!
