It took a million gold coins to repair the city wall, why did Master Lu Xiu still need money?

Tan Chu felt sorry for the large amount of gold coins he had used, and he was full of doubts in his heart.

"Master Lu Xiu, haven't I already given you 1 million gold coins, and the money to build the arrow tower for Lu is still not enough?" Tan Chu asked.

"My lord, one million gold coins can repair all the basic defenses in the city, but all the arrow towers are not counted, and the construction costs of arrow towers and watchtowers are not the same." Master Lu Xiu said with a smile.

"Uh... I only need to build a watchtower that can see the situation outside the east gate, and I don't need to build the remaining four, all of them will be built arrow towers, how many gold coins do you think you need? Tan Chu asked.

"If that's the case, it's enough for me to give me another 200,000 gold coins." Master Lu Xiu said with a smile.

"I need 200,000 gold coins!" Tan Chu looked at him in shock.

"Adults don't know, although the watchtower and the arrow tower look similar in appearance, the arrow tower has one more long-range repeater than the watchtower, and the price is more expensive than this long-range repeater." Master Lu Xiu said.

"Okay, I'll give you 200,000 gold coins, but I'm going to erect 6 arrow towers near the east gate and two outside the south gate." Tan Chu said.

"No problem, I can let you freely designate the place where the arrow tower will be built, according to the request of the adults." Master Lu Xiu nodded.

Tan Chu was helpless, so he exchanged 100,000 gold coins again, plus the 100,000 gold coins that he had saved in the package, and handed them over to Master Lu Xiu...

After receiving the money, everyone immediately came to the vicinity of the east gate and watched Tan Chu plan the placement of the five arrow towers in the open space near the city wall.

Due to the limitations of the system's topography, although the area near the eastern wall is very wide, there are not many places suitable for building arrow towers.

In order to let the six arrow towers at the east gate fully exert their power, Tan Chu worked hard to find a suitable construction site, and finally determined the location of the six arrow towers after half an hour of site selection...

In the open space at the east gate, he set up a three-arrow tower, and then determined the location of the other three arrow towers at a distance of five meters each on the left and right sides of the city gate.

Master Lu Xiu immediately began construction, and as his mallet continued to beat on the ground, pieces of material turned into tall wooden towers...

The location of the last two arrow towers, Tan Chu arranged at the gate of the southern city wall, in case of emergency.

After the arrow tower was completed, I saw 8 mighty veterans wearing black armor, who immediately climbed the arrow tower and began to serve as a guard.

At this moment, the sky has slowly darkened, and a big battle is coming...

However, so far, Tan Chu has spilled out 2.1 million gold coins, and he has also seen results.

The alchemist sent countless potions, all of which were sixth-level life recovery potions and energy-replenishing potions!

There are also a large number of level 6 pet recovery pill bottles...

Tan Chu and the players were excited, because in the main city, the highest potion sold in the pharmacy was only a level 5 potion, and the level 6 recovery medicine had a much more powerful healing effect!

Level 6 Health Regeneration Potion: Instantly restores 480 HP with a cooldown of 8 seconds...

Level 6 Energy Recovery Potion: Instantly restores 480 energy points, cooldown time 8 seconds...

Level 6 Pet Recovery Potion: Instantly restores 360 health and energy points for pets, consuming 8 seconds...

．．．

Seeing the alchemist NPC with a few people sending several large boxes of red, blue, and yellow potions, the players were really shocked...

"I'll go, the money given by the boss actually makes so many high-grade potions?" Shot a large piece of surprise said.

"Well, if these potions are sold in the main city, the boss's money will be paid back soon." Melody laughed.

"I'll get a few bottles of pet recovery potions first." The female mosquito went straight to the package, which contained a yellow medicine bottle.

"Don't worry, take one for each person who needs the potion, take the red medicine for the melee class, take the blue medicine for the ranged one, and get more pet recovery medicine for those who have pets." Tan Chu greeted everyone and said.

"I know it." Everyone rushed up and began to dispense these high-grade potions.

Zhang Daishan and Lin Yurou were no exception, and they stepped forward to take away a lot of blue energy recovery pill bottles...

A set of 99 bottles of Level 6 potions, everyone got dozens of sets!

In this way, they don't have to worry about potions for a long time.

All the potions that the player can use are gone, and I saw the alchemist leave immediately with a few NPCs, and after a while, he brought a lot of boxes...

This time, what they brought turned out to be boxes of strange medicine bottles, each of which exuded a bright black light, which immediately surprised everyone...

"What kind of potion is this?" Everyone stepped forward suspiciously, it was the first time they had seen this kind of black potion bottle, it seemed that there was no such thing for sale in the potion store in the main city...

Tan Chu stepped forward, reached out and took out a bottle of black potion from the wooden box, held it in his hand, and began to observe its properties...

Primary Energy Recovery Potion: A special potion of the system, NPC can restore 10% of the current health after use, and the player can quickly recover 10 energy after use, with a cooldown of 3 minutes.

．．．

Energy Potion?

Everyone looked at each other, confused by the black potion...

Being able to help NPCs recover 10% of their health is enough to see the preciousness of these potions, but helping players recover ten points of energy, they don't understand...

Shenma is energy?

"Boss, what's the energy?" Fallen Leaves in the Wind asked in surprise.

"yes, boss, it's the first time I've heard that term." Shot to death asked in confusion.

"I don't know..."Tan Chu touched his head, not understanding what the attribute of energy is.

Because so far, he has never been exposed to the introduction of the attribute of energy, and of course he does not understand the meaning of this...

"Let me tell you, energy is a hidden attribute of the system, and it will only appear when the player is in an abnormal special situation and needs to make some difficult moves to protect his life." Lin Yurou said with a smile.

"Uh... Miss Lin, can you elaborate on that? Tan Chu asked puzzled.

"This is not detailed enough, that is, when you dive underwater, or run at high speed for a long time and can't stop, the system will determine that your body is abnormal, and there will be a lack of energy to force you to terminate the abnormal state." Lin Yurou said.

"Oh..."Everyone nodded in unison, finally understanding the meaning of the word energy...

It turns out that in the divine realm, there is such a magical thing!

The magical energy value, as well as these magical potions, Tan Chu was suddenly happy.

He finally realized that his money was not spent in vain...
