The reserve team captain looked up in surprise and saw Lin Xuan throw out a huge thunder spear as he spoke to them after turning his head.

Thunder Rock Marrow!

Moreover, he had 25 of them!

The Thunder Rock Marrow was already recognized as the most suitable item to be used as fuel for the Lightning Tower.

However, there were only two ways to obtain this thing.

One way was to search carefully in the belly of the Falling Thunder Mountain and find the Thunder Rock Marrow that condense naturally.

Another way was to find them in the bodies of powerful demon beasts.

For this matter, Old Wu and the others had a headache for a long time.

However, why was it that this guy could actually take out so many at once?!

Mu Yang’s laughter also stopped abruptly. He said suspiciously, “I remember that you only took out a few Thunder Rock Marrow in the last medium-sized beast tide. Do you still have more?”

Beside him, Black, Silver Fox, and the others also asked curiously, “That’s right, Lin Xuan. You still have more Thunder Rock Marrow?”

Lin Xuan chuckled. “To be precise, it’s not me, but Shield Ghost. However, he can’t find the time now, so I’ll speak for him. In any case, the three of us are good friends.”

Shield Ghost quickly chimed in. “Take out my portion of the Thunder Rock Marrow and give it to the reserve team captain.”

“At that time, I got lucky in the Falling Thunder Mountain and found a mine that produced Thunder Rock Marrow.”

Lin Xuan walked over and took out 25 Thunder Rock Marrow from his consciousness space and handed it to the reserve team captain.

The 25 shiny Thunder Rock Marrow illuminated the excited face of the reserve team captain.

Mu Yang’s expression suddenly darkened.

“Damn, how can our luck be so good?!” He gritted his teeth.

Flame Explosion, who was resting at the side, suddenly said, “Lin Xuan, give my share to the reserve team captain. At this moment, maintaining the energy of the Lightning Tower is the most important.”

The reserve team captain looked excited. “You have them too?”

Flame Explosion nodded. “Both Shield Ghost and I keep our Thunder Rock Marrow with Lin Xuan. We trust him.”

Lin Xuan smiled and said, “Alright.”

Then, he took out 28 Thunder Rock Marrow.

“Take it. This is the last of our Thunder Rock Marrow,” Lin Xuan said solemnly.

The reserve team captain was so excited that tears welled up in his eyes. “Thank you, thank you! The Construction Division will not forget your contribution!”

Mu Yang almost gritted his teeth.

Damn!

Why were there so many Thunder Rock Marrow?

He could not help but ask, “Did you also find a mine that produces the Thunder Rock Marrow in the Falling Thunder Mountain?”

Flame Explosion smiled faintly. “Don’t you think that it’s possible that Shield Ghost and I found the same mine?”

Mu Yang was speechless.

Black sighed and said, “Look at their unbreakable brotherhood. They even placed something as precious as the Thunder Rock Marrow in Lin Xuan’s storage compartment. What about you? Why don’t you leave your Mystic Realm Pearls with me? I’m stronger than you. I’ll help you take care of it. This way, you can be more at ease.”

Silver Fox :”…”

Ye Yuqiu and Bai Xinghe also sighed.

Lin Xuan, Shield Ghost, and Flame Explosion simply had an unbreakable alliance.

Mu Yang cursed and ran down the city wall in exasperation.

However, he quickly reacted.

There were only 53 pills in total.

The 53 Thunder Rock Marrow still had to be distributed to the 12 Lightning Towers, and in the end, there were only a few for each tower.

Eventually, the energy of the Lightning Tower would still be exhausted.

So what if Lin Xuan and the other two contributed the Thunder Rock Marrow?

It was only a waste of precious resources!

Thinking of this, Mu Yang became smug again and immediately followed these reserve team members to the other city walls.

As a potion maker, Mu Yang could choose not to go up the city wall. However, now that he insisted on following, the reserve team members also could not say anything and could only let him follow.

After walking down the east wall, the reserve team captain rushed to the north wall.

At first, the situation of the northern city wall was almost the same as the eastern city wall. The reserve team couldn’t collect many items.

However, they were able to obtain a few Thunder Rock Marrow. This was because some of the martial artists had previously bought a few Thunder Rock Marrow in the Falling Thunder Mountain and planned to sell them to the Construction Division in the Little Spirit Mountain. Since the situation was urgent, they decided to contribute.

Mu Yang smiled. It was just a few Thunder Rock Marrow. It could not change the situation of the battle.

“Is this all we’re able to get?” The reserve team captain sighed.

However, he was actually already very happy.

The 53 Thunder Rock Marrow on the east wall had already far exceeded his expectations.

At this moment, a fierce man stepped forward.

“I have something. I hope it can help you.”

The reserve team captain looked up. The other party had already reached 1.9 meters and was already very tall. However, this ferocious man was even a head taller than him. He was 2.1 meters tall.

The most impressive thing was the muscular man’s chest muscles. They were very big.

The reserve team captain’s first reaction was to think that this ferocious man was someone who focused on Strength. However, this person was holding a staff.

Compared to his huge chest muscles, the small staff was no different from a fire poker.

The ferocious man took out some Thunder Rock Marrow and handed it to the reserve team captain.

The reserve team captain counted and said in surprise, “19 Thunder Rock Marrow!”

He asked, “May I know your name? I’ll record all the Thunder Rock Marrow I collected and return it to you in the form of battle merits.”

Muscle Man said somewhat embarrassedly, “They… all call me Brother Milk.”

The reserve team captain could not help but laugh. “Alright, I’ll register then. Brother Milk, 19 Thunder Rock Marrow.”

Mu Yang’s mouth fell open.

Where did these 19 Thunder Rock Marrow come from?

Mu Yang wanted to ask, but the ferocious healer had already returned to the battle.

The martial artists beside him looked at Mu Yang coldly. “Get lost. Don’t waste Brother Milk’s time!”

Mu Yang was furious.

However, he was only a potion maker and did not dare to compete with these burly martial artists. He could only leave dejectedly with the reserve team and head to the next city wall.

On the south wall.

As soon as the reserve team captain arrived, a tall young man in dark green suddenly appeared in front of him.

“Who are you? Why did you come to the south wall? Are you here to provide support?”

A long string of words directly came out of the young man’s mouth.

The reserve team captain was speechless. What kind of high-speed speech was this?

“We’re here to collect items that contain lightning power and use them as fuel for the Lightning Tower. We’ll compensate everyone according to the grade of these items,” the reserve team captain said solemnly.

The young man with the sword said, “How many battle merits will I get if I give a white item? How many battle merits will I get if I give a green item? How many battle merits will I get if I give a blue item? How many battle merits will I get if I give a purple item? How many battle merits will I get if I give a golden item?”

The reserve team captain: “…It would be a waste of time to tell you all this.”

Mu Yang sneered. “In any case, just answer this simple question. Do you have any Thunder Rock, Thunder Rock Marrow, and the like? Lightning Withered Tree won’t do. The lightning elements contained in them are too little. If not, we’ll have to go to the next city wall.”

The martial artists shook their heads repeatedly.

They only had a few Lightning Withered Trees.

They did not have any Thunder Rock and Thunder Rock Marrow.

Moreover, there were only a few items that contained lightning in the Little Spirit Mountain. However, these were all inferior to the Thunder Rock. There were very few items with lightning elements.

The reserve team captain looked helpless and prepared to leave.

“Hey, don’t go. You haven’t asked me.” The young man with the sword stopped him.

The reserve team captain did not know whether to laugh or cry. “I’m still in a hurry to go to the western city wall. Stop teasing me.”

Mu Yang also laughed strangely. “If you don’t have the Thunder Rock Marrow, don’t waste time.”

The young man with the sword directly took out dozens of Thunder Rock from the storage compartment. “Although I don’t have the Thunder Rock Marrow, I have the Thunder Rock.”

Mu Yang was stunned, but he quickly said, “What can a few dozen Thunder Rock do?”

The young man with the sword laughed and directly threw out the Thunder Rock in the storage compartment.

In an instant, it formed a small mountain.

“There are more than a thousand Thunder Rocks here. Is that enough?” He smiled.

Mu Yang :”…”

The reserve team captain’s eyes lit up. “It’s enough! More than enough!”

Although the Thunder Rock was inferior to the Thunder Rock Marrow, the energy contained in the 50 Thunder Rock was almost comparable to a Thunder Rock.

These thousand or so Thunder Rocks were equivalent to more than 20 Thunder Rock Marrow.

When Mu Yang saw this, he was dumbfounded.

“Where did you get your Thunder Rocks?”

The young man with the sword chuckled and said, “I have a friend called Brother Milk. Previously, after the Falling Thunder Mountain advanced to the Seventh Realm, Brother Milk and I went in to take the risk. We accidentally fell off the cliff and accidentally discovered a large number of Thunder Rock at the bottom of the cliff.”

“After digging out all the Thunder Rock, he discovered a lot of Thunder Rock Marrow in the depths. I took the Thunder Rock, and he took the Thunder Rock Marrow.”

“Speaking of which, Brother Milk is really my lucky star. As long as I follow him, I can get lucky wherever I go.”

The young man with the sword chuckled and maintained a smile the entire time.

The reserve team captain was stunned. “Brother Milk, is that the ferocious healer from the northern city wall?”

“Yes, yes, yes! Have you seen him? You must have a deep impression of him.” The young man with the sword smiled.

The reserve team captain nodded. The impression was indeed very deep.

The reserve team captain thought of something and hurriedly asked, “What’s your name? I’ll also record it for you.”

The young man with the sword thought for a moment. “I don’t want to use my real name, but I didn’t give myself a code name either. However, other people call me Poison Blade.”

The reserve team captain nodded. “Alright, Poison Blade. We will definitely not forget your and Brother Milk’s contributions to the Construction Division!”

With that said, the reserve team captain led his team members straight to the last city wall, the western city wall.

Mu Yang gritted his teeth.

What was going on?

Why were there people who could take out items that contained lightning power on every city wall?

Soon, on the western city wall.

The reserve team captain explained the situation as usual.

The martial artists shook their heads repeatedly.

Only a few people took out items like the Lightning Withered Tree.

No one even took out the Thunder Rock.

Mu Yang calculated carefully. Currently, he had collected about 80 Thunder Rock Marrow from martial artists.

They needed to distribute 80 Thunder Rock Marrow to 12 towers. There would be less than 7 Thunder Rock Marrow for each tower. However, with the current energy consumption speed of the Lightning Towers, these were far from enough.

Moreover, now that beast-shaped ghosts have appeared, the energy consumption will increase faster and faster! Mu Yang sneered in his heart.

Unless someone from the western city wall took out 40 to 50 Thunder Rock Marrow at once, it was impossible for them to turn the tide.

The energy of the Lightning Tower would definitely be exhausted before dawn!

The martial artists from the three colonies would have no choice but to fight the ghosts.

In that case, they would definitely suffer heavy casualties!

“I have a bit of Thunder Rock Marrow.”

At this moment, a tall young man in white with a cold expression raised his hand.
