In the Spirit Gathering Formation, after frantically transforming and absorbing the gray mist soul energy for a few days, Han Feng finally replenished most of his soul energy, and the reason why he didn't fill it up was because the two skeleton leader younger brothers who had been sent out to perform the mission had returned.

Since the two skeleton leader brothers are not like the black knight brothers, they don't walk very fast. It's taller and has longer legs, so it's limited if it's faster than the average skeleton warrior. So Han Feng asked them to go out and hunt ghosts and collect skeleton warriors around, and the range was not very far. So on the contrary, the two skeletal leaders who were slow down completed the task and came back first.

The two skeletal leader brothers brought back a total of five ghosts for Boss Han Feng, and none of them were high-level; There are also fourteen skeleton warriors, and one of them is a high-level one.

However, the little brother of the skeleton leader himself is not of high grade, and the surrounding high-level undead creatures have already been searched by the Death Knight Marcus, so it is impossible to ask for too much.

Han Feng looked at these five ghosts and a total of twenty-three skeleton warriors, oh, let me explain, when Han Feng captured Bone Mountain before, the skeleton warriors were not all killed by the fierce spirit brothers, and there were still nine of them left with small lives, so there were twenty-three in total.

Among them, there are ten high-level skeleton warriors. Han Feng collected these undead creatures that were not high-level, and he was going to use them for real purposes. I want to try to use the magic secret method to refine and strengthen them, will there be any problems in the future?

And if it succeeds, it will be able to improve the overall strength of the younger brothers under his command. In the future, it will all depend on the junior brothers, and Han Feng needs more time to cultivate and increase his soul strength as quickly as possible.

According to Han Feng's estimate, if he can't increase his soul strength to the level of an intermediate undead lich within half a year, he will likely end up in tragedy in the face of the upcoming crusade troops of the Lich King Badair.

Therefore, improve the strength of the little brothers, let them rob, and then grab back more little brothers, more materials, and let more little brothers go to more places to rob...... In this way, you can expand your sphere of influence as quickly as possible and improve your strength level. This is Comrade Han Feng's plan and goal for the next six months!

First of all, Comrade Han Feng got a low-level ghost, and without saying a word, he directly infused its soul energy into its soul body. In the struggle of low-level ghosts, this is because it has become an instinct for low-level undead creatures in the undead world to obey high-level undead creatures, and the more intelligent undead creatures are, the more so.

The only struggle of the low-level ghosts is because the intense pain in the soul is unbearable, and they instinctively resist a little. This looks similar to the situation of domestic sheep when they are about to be slaughtered!

Therefore, most of the low-level undead creatures in the undead world are still very tame! Why is this so strange!

In a moment, the soul burst of the low-level ghost that was forcibly infused with soul energy! It's completely gone!

Han Feng roughly estimated the soul strength of the ghost and the soul energy infusion strength that it could withstand. These are the most important basic bases in the following realities, and it is impossible to sacrifice a low-level ghost.

Next, Han Feng began to use several demonic secret methods, and began to conduct different experiments on the remaining four ghosts one by one.

I still have to explain here that it's not that Han Feng prefers magic secret methods.

Rather, Taoist exercises pay more attention to the improvement and cultivation of one's own realm, and in addition, it attaches importance to the magic weapon and Taoist instrument that is related to life. It can be said that the methods of the Taoist family are more gentle, and they pay more attention to themselves, of course, there are some partial methods such as puppetry, beast control, etc. But the beast control methods are also both Taoist and demonic.

The Demon Dao Exercises are different. There are all kinds of demonic bloody methods such as fierce spirits, evil ghosts, blood demons, demon heads, corpse refining, etc. These are all quite applicable exercises and skills in the ghost place of the undead world.

Moreover, although these demonic exercises are relatively cruel, bloody, vicious, and vicious. However, if the objects are all these undead creatures in the undead realm, Han Feng will not feel that there is any problem of conscience at all!

Besides, Han Feng is not a noble moral gentleman or a virtuous monk, he himself is a battle maniac who has risen to immortality by fighting and fighting. Then you won't feel any guilt about destroying some undead creatures! The so-called guilt is only the thoughts of little white sheep who have been kept in captivity at home and have never seen the wind and waves outside!

In Comrade Han Feng's philosophy, struggling to survive and the law of the jungle are the truths that are applicable in any realm.

There is no need to elaborate on the actual process, anyway, I can't see where to go, and the cruelty and tyranny are needless to say.

And the end result is not too good. Four ghosts, two of which exploded directly; A consciousness is lost and becomes a complete blank energy body; The last one seems to be crazy, flying around, constantly frantically consuming his soul energy, and finally being able to exhaust his soul and hang up! Depend on!

Well, the reality of the soul body is over! However, Han Feng was not too disappointed with the result.

These realities have long been doomed to failure, or because of a lack of materials. Without blood, yin qi, medicinal herbs and other materials necessary for the use of magic secret methods, if you want to succeed, you can only hope for a miracle!

However, through Guò's observation, Han Feng still has a certain harvest. It's not too much of a problem if the strength of the soul body is not high, as long as a few suitable formations are properly arranged. Han Feng can completely give birth to a high-level ghost level soul body.

However, the ghosts were all consumed, and Han Feng turned to face a group of poor skeletal warriors who were dumbfounded.

If you want to improve the strength of the skeleton warriors, it is the easiest thing for Han Feng.

Just sacrifice the soul fire to help them strengthen their bones and weapons. Even low-level skeleton warriors can easily defeat high-level skeleton warriors after this kind of enhancement.

This principle is very simple, you just need to imagine that skeleton warriors are equivalent to ordinary human soldiers, and if you change the soldiers to stronger armor and sharper weapons, then the combat effectiveness will naturally be upgraded to a higher level.

But that's not realistic. After all, Han Feng is not a machine. Soul fire refining consumes a lot of soul energy and time. Han Feng is tired to death, and he can strengthen a few skeleton warriors!

Therefore, Han Feng's plan is mainly on the formation, and Han Feng plans to use several formations to see if he can strengthen the skeleton warriors in batches.

Then, Comrade Han Feng began to lay out the formation again. The few energy bones on hand were also used as a power source for the formation.

According to Han Feng's understanding, the skeleton warriors' own strengthening bones mainly rely on absorbing gray mist and soul energy to nourish them. It's just that this method takes hundreds of years.

So if you gather a large amount of gray mist and infuse it with soul energy, can you get an acceptable result?

Han Feng first set up a large-scale Spirit Gathering Array, which was mainly used to attract a large amount of gray mist around the convergence. A small array was set up in the Spirit Gathering Array to convey soul energy, and a small array was also set up in the center of the formation to concentrate all the gray mist and soul energy on the skeletons of the eight skeleton warriors of the first batch of real yàn according to the direction of the eight trigrams.

And Han Feng was even more busy wandering around during the operation of the formation, marking various soul marks, talismans, and demon duels on the eight skeleton warriors. To examine the strengthening of the skeleton bones by various means, after all, there are still a few younger brothers to strengthen later.

Two days later, the three Black Knight Brothers also returned. They have horses and are still quite fast, so the mission range is longer.

However, due to the number of newly recruited skeleton warriors on the return trip, this speed is not fast. That's why it's two days slower than the Skeleton Boss.

They have to harvest more, the ghosts have brought back eight, and none of them are high-level, there is no way, the strength of the black knight's soul itself is not high, and he can't scare others! It's a bit harder to get them to catch the spirits.

There are quite a few skeleton warriors, forty-three. But there are only two high-level skeleton warriors.

It seems that Marcus, the Knight of Death, was quite ruthless in his looting of the surroundings before, and the high-level warriors were basically brought back by it. It didn't look down on the mid- and low-level fighters, so there were a lot of leftovers around!

Aha! It's not bad, the real yàn material is there again! Comrade Han Feng's eyes immediately lit up, staring at the eight poor ghosts who had just arrived.

Oh! The brutal destruction of the little undead in the undead world has begun again. Death is on top! Grill this sinner with the fire of the undead! I can't stand it!
