The Lich's family is truly rich.

Those lichs are basically old monsters who have lived for hundreds of years or thousands of years, and even if the Soul Tower they built only collects ten souls a day, it is 3,650 souls a year, and tens of thousands of souls in ten years. However, considering that the tower may have an upper limit on how much it can hold, the soul here should have something to do with the dark blue flame at the top.

"Gain 8 Killing Powers."

"Gain 1 Soul."

"Gain 4 Killing Powers."

"Gain 11 Killing Powers."

"Gain 1 Soul."

Within the scope of the flame realm, one by one skeletons fell one after another, and today's undead seem to have become a little stronger, because the number of archers has increased, and occasionally some skeleton mages can be seen, who can throw out black energy arrows.

Suziyu is really happy to brush today.

This time he gathered the Fire Burners, and then used the Berserkers as bait to let them rampant through the pile of undead, but it only took a few moments to attract a large number of undead, and then a wave of flamestorms directly covered the blow.

The efficiency has been significantly improved, that is, the chance of the Berserk Demon dying has increased.

But it's all worth it.

Because Su Ziyu's income as long as he pulls a wave of monsters is much higher than that of the Berserk Demon itself, considering that there is also a lich here, of course, it is the pursuit of efficiency first.

"Almost."

Today, Su Ziyu killed thousands of undead again, and gained about 30,000 points of killing power, plus about 1,500 soul points.

It was only after he noticed that a ghost had appeared in front of him that he decided to retreat temporarily.

Eighty percent of the claw demons were killed today, but there were two elite units, and the berserk demons died eight, nearly half of them were besieged and killed by the sudden appearance of ghosts, and the other demons had no losses, at most they were injured.

The losses are still within the scope of bearing.

Su Ziyu turned around and rushed out with the demon, preparing to change positions tomorrow and do it again.

"Finally retreated."

A ghost floated in the air, and said with a worried expression, "The demons are about to rush in today." ”

"I don't know if the bones will hold them for a few days."

Soon.

The ghost flew all the way to the Spiritualist Tower, and today the demons killed a lot of undead, and it had to go over and activate the Spiritualist Tower to resurrect it.

Now I only hope that the Buried Bones can block these demons for a few more days, so that they will not disturb their master's research.

It's another day full of harvest.

Su Ziyu directly expanded the number of little devils to three thousand, with so many laborers, soon the base camp also changed, one building after another is under construction, a wall has been built on the periphery, a large number of little devils are carrying materials to extract ores, and now they have replaced the vassal race as the main force of labor.

"Ding!"

"The Abyssal Blood Pool captures a high-quality soul."

Just when Su Ziyu was lying on the stone chair enjoying the massage of the succubus adjutant, suddenly a prompt sound from the system came.

Got a harvest again?

Su Ziyu got up directly and came to the abyss blood pool.

- "Minotaur Soul (Excellent Quality): The soul of an elite Minotaur warrior may awaken some special talents after being transformed into a demon, and the killing power consumed by the Demon Advanced Mutation will be reduced by 20%. ”

Interesting!

It seems that if a strong person is killed in battle near the abyssal blood pool, their souls may be captured by the abyss blood pool.

The succubus lieutenant just said that the minotaur in the west is at war with the ogre, and today the abyss blood pool captured the soul of a minotaur warrior, and the soul of the fire giant from the last time also came from this.

Today's Su Ziyu has a lot of money, and he directly extracted this soul and promoted it to become a berserk demon.

Really.

It's an elite unit again, with the only difference being the addition of 'Fury' and 'Mighty Charge' abilities.

Nothing to say.

Su Ziyu waved his hand to promote him to a berserker demon, and then arranged for someone to take him to the barracks.

Now Su Ziyu does not lack killing power, nor does he lack soul value, but the demon gene is a little insufficient. Demon genes are the key resources for promoting mid-level demons, and now he doesn't promote low-level souls, only high-quality souls will be promoted, because their potential after advancement is greater.

The next day.

Su Ziyu once again led his demon army to the place of bones, and today's undead seemed to be a little less, and the dark blue flames at the top of the Soul Calling Tower were also dimmer a lot.

But today's harvest is still okay.

Su Ziyu still killed thousands of undead, and then evacuated with people after seeing the ghosts.

"Are these demons afraid of ghosts?"

"Why retreat as soon as you see a ghost? Should I summon more ghosts? In the distance, a ghost muttered.

Day 3.

At the same time, Su Ziyu appeared again with the demon army, and there seemed to be fewer undead today, and the dark blue flame at the top of the Soul Tower seemed to be a little dim.

"It looks like I can't brush it a few times." Su Ziyu's expression was a little regretful.

This time they encountered quite a few ghosts.

Since there are not many other undead, the ghosts also have to be killed, it is still twenty or thirty thousand killing power, plus seven or eight hundred soul points, Su Ziyu retreated after harvesting enough.

"I can't stop them if they go on like this!" In the distant sky, a ghost felt like he was sweating profusely.

The soul power stored in the Soul Tower has been almost exhausted.

If this continues, it will only take a day or two for the demon to break through the defense line of the Buried Bones.

"I can only rely on the master's magic circle." The ghost made up her mind.

Day 4.

Su Ziyu arrived as scheduled with the demon army, and the number of undead has really decreased again, and now it looks a little sparse, and if you want to farm monsters, you have to let the berserk demons rampage and pull monsters for a while.

"It's a pity."

"There shouldn't be much left tomorrow." Su Ziyu said regretfully.

However, today's harvest is not bad, in addition to obtaining a large amount of killing power and soul points, a snake demon and a fire demon have also advanced to elite units, and the berserk demon has even appeared seven or eight elite units.

Day 5.

After seeing the figure of Su Ziyu and his party, the ghost in mid-air lamented: "Sure enough, it's here again!" I'm afraid I won't be able to stop them today! ”

"The high-level undead in the Bone Fortress must be awakened."

At this time, the flames of the Conjuring Tower were already very dim, Su Ziyu had only gained more than 10,000 points of killing power today, and he had already seen the bone fortress in the valley, exuding the aura of evil and death from a distance.

However, just as the ghost was about to activate the withering array to awaken the high-level undead, Su Ziyu left here with someone again.

"This place has to be kept."

Su Ziyu said secretly: "Raise it for a period of time first, maybe you can continue to farm monsters next time." ”

There will be no undead in the short term.

Su Ziyu has never seen that lich, it is too dangerous to attack the bone fortress, and the siege battle is not easy to fight, so it is better to keep it for a while.

He was ready to deal with the Red Dragon.

In case the casualties are too great, he can continue to come back and farm the undead.
