Tian Yuan Ling, the city lord's mansion.

The moon is in the sky, but it is covered with a faint, lingering red.

In the middle of the night outside the territory, the monster roars more and more every day.

"It's time to prepare."

"Preparations to fight the monster tide."

"In addition, in this Dragon Court dispute, the lords of Luofu Mountain seem to have done a little cover for me, but ......"

But it was only a matter of time before Tian Yuan Ling was exposed.

As long as the territory grows stronger, sooner or later you will have to face enemies from the depths of the wilderness, from enemy countries.

It's just that shepherds are too dazzling and will advance the process.

Therefore, he also had to prepare in advance for the worst-case scenario.

Mu Yuan was on the wall, projecting the list.

This is the exchange list of the Taixuan Covenant. In this Dragon Court battle, he won glory for Taixuan, in addition to the recruitment names of 50 Dragon Court Lands, he also got a large amount of Taixuan contribution points.

Back then, the 'Nine Xuan Cultivation Liquid' that the Lord Mu had never forgotten was only 1,000 points at an exchange price.

He decided to chop his hands and exchange them for two more.

However, at the moment, he is already a third-order general-level powerhouse, and the Nine Xuan Cultivation Liquid does not play much role, but he can continue to consolidate the foundation, what if, there is an additional gain?

Left and right are not expensive.

Rich and capricious.

Mu Yuan mainly wants to exchange for two types of treasures - one is a treasure that can strengthen the defense of the territory; One is the treasure that can make money.

The former is needless to say.

The latter, after all, he needs to constantly acquire remnant souls. Although money is not equal to remnant souls, without money, it is definitely impossible to buy remnant souls.

Exchanging valuable contribution points for soul crystals is the stupidest option.

He made such an exchange back then.

But back then, he had no choice, he was in dire need of soul crystals, and now he definitely can't change like this.

"Either exchange it for precious treasures and sell them to other lords in exchange for a large sum of soul crystals, or ...... It is a cash cow that can be exchanged to make money continuously. ”

Mu Yuan exchanged a few miracle blueprints of the golden fertile soil and some rare crop seeds.

The drawings of the Fountain of Life show that they are 'out of stock', and it seems that this building is much rarer.

"The Guangyuan Chamber of Commerce finally got the approval for the sale of pharmaceuticals not long ago, and can sell drugs in the shops rented in Shiling Town, and according to market research, the sales of drugs without side effects such as vitality drugs have always been good, so ......."

"Building Upgrade Stones"

"Grade: Excellent"

"Description: Can be used to increase the rank of the Miracle Building outside of the class building, up to the Excellence level."

Using this Upgrade Stone will raise the Fountain of Life to the Superior Tier, greatly increasing its production and the quality of the items it produces. After the upgrade, the fountain may have a small chance to produce some droplets of Life Eaux.

Mu Yuan made calculations and came to the conclusion that it was worth upgrading the fountain of vitality.

He circled it a little more, and he was able to sell it quickly in exchange for a large amount of soul crystal treasures.

Tentative.

Rather than money, strengthening the province's defenses is the most important thing at the moment.

Mu Yuan found a staff officer from Isloya.

"The rare-level permanent city wall blueprint, Lord Lord, you have already circled it, well, that's it, it's not worth exchanging for the excellence-level one."

After all, permanent drawings are too expensive.

The original purpose of the city wall was to block a large number of ordinary monsters.

The 'Black Rock Wall' of the rare grade is sufficient. If a powerful monster appears, it can be handed over to the generals to kill in a targeted manner.

He has enough generals here to cut down the enemy.

Isloa continued, "Depending on your budget, we can probably exchange three or four Excellence Tier Defensive Buildings, as well as matching building materials. My suggestion is that the main cell kills, preferably with the ability to weaken and control. ”

"As for mass killing, we have Dorai and the Spell Crucible, and there is no shortage at the moment."

The Great Lord of the Truth also understands, he asked Isloya to come over mainly to catch the strong man, and browse this dazzling exchange list together.

At present, the most powerful killer weapon in the territory is indeed the 'Nine-headed Roaring Thunder Flame Dragon'.

Although this large-scale spell has the same name, it is actually 'Lei Yanlong v3.01 version', and its destructive power and coverage are far beyond the original.

It's not that the spell formula has been improved.

It's just that the people who brand spells are countless times stronger than before.

This refers to Admiral Dorai's Spell Energizer.

Now the third-level spell furnace is stored with a new version of the 'Ten Thousand Trees and Green Vines Two Yi Arrays' and a large and two small 'Nine-headed Roaring Thunder Flame Dragon' with a total of three shots. The large ones occupy 10 storage slots and the small ones occupy 5.

Moreover, at Mu Yuan's suggestion, the Great Thunder Flame Dragon Technique, Dolai entered the state of 'Overlimit Devouring' and then used thunder and fire to condense. With this set of spells alone, Dolai and Ishloa were busy for three days and three nights.

It was only completed last night.

Its power shepherd someone can't even imagine. There are also drawbacks, too violent energy cannot be finely controlled, and naturally cannot be used in or near the territory.

Throw farther.

In order to make up for the lack of large-scale spells, Mu Yuan and Ishloa picked half a night and selected two defensive buildings.

Necronomiconomic Tower (Excellence)

"Explanation 1: It can gather necromantic energy and shoot necromantic beams through the hole. Those who are struck by the light of necromancy will suffer from the loss of life, sluggishness, weakness, and blindness, in addition to the normal energy damage."

"Note 2: The Necronomicon Tower is recommended to be built in an area where the undead energy is abundant, and at the same time, this defensive structure can enhance the lethality of the Necromantic Beam by absorbing the undead energy of the surrounding heaven and earth."

"Note 3: The output of the Necronomicon Tower has the normal 1st, 2nd, and 3rd gears, and the unconventional 4th and 5th gears that require the help of external forces."

This building is perfect for a skeleton graveyard.

Its range radius is enough to radiate most of the Celestial Yuan Territory.

The second defensive structure, called the 'Ice Tower', is similar in size to the Necro Tower. Slightly less lethal than the former, but with the ability to lock enemies from a distance.

The two outstanding buildings, as well as the cooperation of one of the territory's subordinate generals, roughly built the defense system of the Tianyuan Territory.

The third outstanding building, Mu Yuan's checkbox, is not a defensive building, but a special building 'Spell Celestial Sphere'.

After that, Isloya purchased a batch of formation bases and props, and prepared to arrange more defensive barriers, detection barriers, and shielding barriers in the territory.

……

The Elven Courtyard of the Secret Realm.

Mu Yuan once again found the Cold Moon City Lord and helped him purchase goods on his behalf.

"After all, contribution points can't be traded, and it's not easy to exchange such a large amount of treasures, you understand, Big Cold Moon."

Understand, understand, understand.

But it's annoying!

She's the lord of Cold Moon City! How many times have you been a purchasing agent for Tian Yuan? But think about it carefully, is the battle of the Dragon Court the Tian Yuan she recommended, the root of this contribution point exchange, or is it herself?

That's it, it's true that only she, Lord Hanyue, can exchange a large amount of treasures for Tian Yuan.

"Let me see...... Well, the few miracle buildings I picked are quite practical, yes, I thought you would pick ......."

She originally wanted to talk about the Evolved Things, the High-level Remnant Soul, and the quota of the Land of the Dragon Court, but when she was about to say it, she thought that Tian Yuan didn't need these at all, so she changed her words in time.

"I thought you'd pick a second- or third-order class building, but for you at the moment, it's true that defensive buildings are more important." The Spell Celestial Sphere is also good, as long as the spell ripples are cleverly set, you can detect and find enemies from a distance, and when the time comes, with the defense building, you can achieve accurate sniping of strong enemies. ”

Mu Yuan nodded.

With this spell celestial instrument, like the previous A-class agent Victor, I am afraid that he will be discovered before he even sets foot in the territory.

However, there was a deeper reason why he chose this building.

The Spell Globe and the Spell Forge are all parts of an epic building. And now, it's just a 'spell hub'.

Two days later,

Looking at the cold moon city lord who was troublesome but acted resolutely, he brought him a treasure to buy on his behalf.

"Well, you can count it, and if it's okay, sign it."

"And this, this is an extra prop given to you above, but it's best not to use it if it's not in a desperate situation, this kind of thing is also very rare, and when you become strong in the future, you don't need it, remember to take it back, and you can exchange it for a contribution point."

It was a white jade-shaped prop with two tiny cracks on it.

"Runestone: Divine General"

"Description: You can summon a god general with legendary combat power and fight at your command. God will last up to three hours."

"Note: The number of uses remaining (1/3) of this item."

Mu Yuan stared at the half-ring, silently earning, "Yes." ”

……

The next day, boom.

In the skeleton cemetery, a black tower twenty or thirty meters high stands in the middle of the mound. All around him was a black mist that gathered and swirled around the Necronomical Tower.

At the top of the tower, a black hexagonal crystal slowly rotated.

"Since the construction of the Tower of Necromancy, the undead energy between heaven and earth has increased by about 0.03%, and it should still be rising."

The dead bones pondered.

Mu Yuan looked at this remarkable building that blended perfectly into the surrounding environment and did not look much grandiose, and said, "Probably, the Necronomicon Tower has accelerated the circulation of undead energy, and in fact, the skeleton graveyard is also slowly expanding, but it is not obvious. ”

"If we can build more undead buildings in it, we can probably increase the expansion rate of the cemetery, and even transform it."

The frost dragon Sario looked at this, and it didn't see much of a tower of necromancy in its eyes.

The big pupils revealed even greater confusion.

"Can this thing really kill a strong enemy?"

Mu Yuan glanced at it, "It's better to try." ”

Defensive buildings need to be drilled, so that the chain will not fall at critical moments.

The invincible Frost Dragon, of course, will not be afraid of this small challenge.

"Let's fight!"

It hovers in the air at a height of tens of meters.

Soon, a ghostly light flashed above the Tower of the Necromy, and a black light hit the Frost Dragon.

Soon.

But the Frost Dragon was unharmed.

The Dragon's Soul and Dragon Armor give it great defensive power.

"It's just a small tower, how can you hurt Ben Long."

"So, let's try the second and third gear energy output."

Mu Yuan spoke.

Bone Manipulation.

Soon, a ghostly light that was several times deeper flashed above the Tower of Necromancy, and an incomparably condensed beam of necromantic light burst out.

And without a standstill, the hole shot a third, more dimmer glow.

In an instant, a huge gap was blasted open in the frost dragon's wings, and countless black particles were dissipating.

It fell from mid-air with a thud.

Half a sound, only to realize that there was an unknown ......

"Huh?"

Is it being knocked down? What just happened!
