—You don't know if you don't try it. Try to think about the number of zombies you want to sacrifice and use the skill!

That was what Zaneos said to him. However, if the method did not work, it would waste their resources. Millions of zombies mixed from stage-2 to stage-7.

He was not surprised if he summoned a being that was as strong as Rumru with the number of the sacrifice.

"Let's try then. If the resources are wasted because I summon an overly strong spirit, all the blame is on you, Teacher," Tang Shaoyang teased the Demon Swordsman.

Before he heard any retort from Zaneos, he extended his hand. He thought of a number, forty thousand. That was the number in his head.

[Spirit Summoning]

The zombie corpses exploded into black smoke. It was the same smoke as the beforehand summoning. The smoke swirled into a spot.

"Don't tell me it's another demon or undead," Tang Shaoyang muttered in a low voice.

However, despite the phenomenon that the spirit was most likely an undead or a demon, he discovered that not all the zombies were sacrificed. The method was working, only forty thousand zombie corpses were sacrificed.

Gan Shuo was gathering with his friends, to his surprise, everyone survived and the battle ended with zero casualties. The injured… No, there were no injuries as they were immediately healed by the white moth or the people from the Healer Division.

After the tough and long battle, it was time for them to share what they had experienced. Gan Shuo was sharing his experiences first, not about him though, but about Supreme General Zhang Mengyao.

He told them how the Supreme General inspired his fighting spirit. He was sharing his deep admiration toward his superior with no impure intention.

Suddenly, Gan Shuo stopped as he felt a slight vibration from the ground, "What's that? Another enemy?"

"Don't worry about it. It's Lord Shaoyang, he is cleaning up for us," Cao Yuntai told Gan Shuo to continue with his story. He said nothing wrong, Tang Shaoyang was cleaning up the aftermath, cleaning the zombie corpses for the spirit summoning. The vibration might be caused by the battle with the summoned spirit.

"Are you sure? Shouldn't we help him?" Liao Zhenya asked Captain Cao.

"If you want to watch, you can, but you are not able to help him, none of us could help him," Cao Yuntai said mysteriously.

"Talking about Lord Shaoyang, where was he when we fought the zombies?" Gan Shuo was bold enough to ask Cao Yuntai.

Of course, Gan Shuo was not the only one who was curious, everyone was. It was just that the others were not as bold as him to ask that.

Cao Yuntai smiled, "I know you might have a suspicion, but I am pretty sure everything what you think about him is wrong. But, I think it's best if he does not help us. If he helped us, your level should be lower than your current level. He, not joining the battle for our benefit."

Hearing that, everyone subconsciously checked their current level. Gan Shuo also opened his window status. After the battle was over, taking rest was what was in mind. He did not check his gain from the battle.

His eyes went wide to see his current level. During the battle, he hardly checked the window status. Each time he leveled up, he would automatically allocate the free attribute points and continued fighting.

But now, he was shocked to see the number, he was level 97. Gan Shuo blinked his eyes a few times. He then rubbed his eyes time and again.

"This… This… This…" he gained 62 levels in one battle. This was unbelievable.

"You finally see the gain," Cao Yuntai shook his head as he smiled at the newcomers.

[Do you want to sacrifice the Grade B+ Spirit, Goran the Undead Commander? Yes/No?]

[You have sacrificed Grade B+ Spirit, Goran the Undead Commander!]

[You gained 22 levels and a random skill of Goran the Undead Commander!]

[You have obtained a skill, [Greater Strike]!]

"This skill is cheating. I can level endlessly as long as I have enough sacrifice resources," Tang Shaoyang muttered as the Undead Commander in his hand slowly dissipated into smoke.

—Increase the number of sacrifices, summon Grade A Spirit, or even Grade A+ Spirit. Let's test out how strong you have become.

Zaneos spoke through his head. Tang Shaoyang could feel the excitement from Zaneos through their connection. Zaneos wanted him to go through another advancement.

—No, let's reduce the number of sacrifices and summon Grade C Spirit or Grade C+ Spirit instead. He is Level 287 now if we summon a higher grade spirit, we will waste the sacrifice materials as his level will be stuck on level 300. The border level for advancement, don't forget about that!

Zowen reminded them in time. Level 100 for the first advancement, level 200 for the second advancement, and level 300 might be the third advancement.

"Ten thousand? Let's make it safe to fifteen thousand," Tang Shaoyang summoned another spirit with fifteen thousand zombie sacrifices.

[You have summoned Grade B Spirit, Porton the Undead Commander!]

"It seems the sacrifices related to the spirit I will summon. Three times of zombie sacrifices and all of them are undead. But Karan is a different case," Tang Shaoyang tried to guess how the summoning worked.

He summoned Karan with zombie sacrifices, he still remembered the first summoning. Monster sacrifices, he summoned Feera. Ant sacrifices, he summoned Malki the Fire Ant Emperor. Fogged Ape sacrifices, he summoned the Demon Swordsman. It still related as it seemed the demon blood ran through in the Fogged Ape. Pride was a prime example that the Fogged Ape Tribe was related to the demon.

"Nah, since all of them are undead. They are suitable spirits for the sacrifice," Tang Shaoyang did not try to speak or negotiate with the spirit as he forcefully subdued the undead spirit, "Let's make it quick and finish all the sacrifices!"

Grade B Spirit, weaker than Grade B+ Spirit. There was no need for the [Spirit Integration] and [Dragon Transformation]. He easily beat the Undead General into submission.

[Do you want to sacrifice Grade B Spirit, Porton the Undead General? Yes/No?]

[You have sacrificed Grade B Spirit, Porton the Undead General!]

[You gained 20 levels and a random skill of Porton the Undead General!]

[You obtained a skill, [Undead Poison]!]

After he sacrificed the undead spirit, he immediately checked for the window status. He was now level 307, but there was no notification for the advancement.

"Level 300 is not the border for advancement. Level 400 or level 500 should be the border of advancement," Tang Shaoyang concluded after seeing the window status.

—It seems so.

Zowen responded shortly.

—Then what are you waiting for, let's summon the next spirit. Let's increase the number to fifty thousand.

For the first time or maybe the second time, Tang Shaoyang did not count that, the Demon Swordsman lost his composure. Zanoes seemed to be excited with the quick leveling. He could understand that as this was related to his resurrection.

"Alright then, fifty thousand zombies, is it?" Tang Shaoyang entertained the demon swordsman. He was oblivious to the incoming of the Daian Kingdom's main force.
