For most of the remaining half of the day, Comrade Han Feng and his younger brothers were still absorbing soul energy with all their might in the Spirit Gathering Formation! And the skeleton warrior brothers who didn't have their turn outside the formation were not idle, they were busy collecting and capturing all kinds of high-level soul bodies and ghosts, and continued to devour them to strengthen their own souls!

This method of devouring the soul body to strengthen one's own soul has achieved very obvious results after a period of continuous progress. The junior brothers under Han Feng's command, especially the high, medium and low-level skeleton warriors, their own soul strength is gradually rising. Among them, there are several mid-level skeleton warriors and dozens of low-level skeleton warriors, all of whom have obvious signs of being promoted!

And among the high-level skeleton warriors, it seems that many of them are about to reach the soul limit strength of the level of high-level skeleton warriors, and it is estimated that in less than a month, there will be several high-level skeleton warriors who have the possibility of advancing to the skeleton boss.

Of course, although there is a possibility of this kind of promotion, according to the practice of the undead world, the chance of really being able to advance is very small! Most of the high-level skeleton warriors will end up with a failed promotion and soul destruction in the process of advancing to the skeleton boss!

And among the more than 200 high-level skeleton warriors at present, the one who is most likely to be the first to advance in the near future is the personal follower of the Typhoon classmate - the senior skeleton warrior who once fought hard with a two-meter-long huge bone knife and the tail of a giant beast skeleton! In fact, according to its strength, it was already close to the limit of a high-level skeleton warrior. After this period of soul strengthening, it is not surprising that he can be the first to advance!

Sure enough, after half a day, in the process of rotating into the Spirit Gathering Formation to absorb soul energy, seven mid-level skeleton warriors and thirty-one low-level skeleton warriors began to advance one after another!

However, there is no danger in raising a small level like this, and the time it takes to advance is very short. Of course, after this kind of small-level promotion, the strength of the skeleton warrior junior brothers will not improve too much.

Generally speaking, after an Intermediate Skeleton Warrior is promoted to a Senior Skeleton Warrior, his strength is generally doubled. Of course, there are also some mid-level skeleton warriors with relatively high soul quality, or it can also be said that they have relatively good qualifications, and after being promoted to high-level skeleton warriors, their strength may also increase several times or even more than ten times.

In fact, as long as you look at the strength that the skeleton warriors have improved after being promoted to the small level, you can basically see whether this skeleton warrior has a future. In other words, if an intermediate skeleton warrior can be promoted to a high-level skeleton warrior and his strength can be increased several times, then this guy will have a greater chance of being promoted to skeleton leader in the future!

However, a promotion at a large level such as the promotion of a high-level skeleton warrior to a skeleton leader is a very dangerous thing to do, and it takes a long time. And in the process of this promotion, you must not be disturbed, otherwise it will definitely be the result of failing to advance and the soul will be destroyed!

Comrade Han Feng noticed the signs of the promotion of the skeleton warrior brothers at the first time, and he was obviously very happy. He also deliberately dedicated part of his mind to pay attention to the situation of these promoted skeleton warrior brothers.

Since the last time the Typhoon junior was promoted from an intermediate skeleton warrior to a senior skeleton warrior, it was carried out and completed immediately after a big battle with a high-level bone dragon, due to the urgency of time, Comrade Han Feng did not have the opportunity to seriously observe the promotion of this skeleton creature in the undead world.

In fact, at this time, Comrade Han Feng had already begun to consider the risks that the skeleton warrior brothers would face when they were promoted in the future. After all, the little brothers here are all accumulated and trained by themselves with great difficulty. With Comrade Han Feng's short-sighted and stingy personality, he naturally doesn't want to see the younger brothers lose in vain because of the failure to advance!

In this way, it is necessary to spend some time to study the promotion process of the skeleton warrior brothers, and Comrade Han Feng still hopes to use his own means to reduce the promotion risk of the skeleton warrior brothers as much as possible!

A day later, the skeleton warrior troops commanded by the undead lich Usr had already approached more than thirty miles away from Comrade Han Feng and his younger brothers. In fact, as early as when the undead Lich Usr and its troops approached the range of more than 100 miles, Comrade Han Feng had already begun to notice their pursuit.

However, Comrade Han Feng did not think that with the pursuit speed of the immortal lich Usr and its skeleton warrior troops, he would really pose any threat to himself and his younger brothers. Therefore, Comrade Han Feng has also been calmly continuing to absorb soul energy.

It wasn't until now, when the undead lich and its skeleton warrior troops were already approaching a distance of thirty miles, that Comrade Han Feng began to command his junior brothers to stop absorbing soul energy, pack up a few things, and prepare to continue on the road!

The process of packing up and preparing this qiē seems unhurried and unhurried! It felt like packing up and getting ready for an outing!

After all the qiē was packed up and prepared, all the junior brothers became all-cavalry fast mobile troops again.

At this time, the undead lich Usr commanded his army of skeleton warriors and had already pursued it for more than ten miles. Even standing on top of the head of the high-level bone dragon, you can see the figure of the army of skeleton warriors with the naked eye, and the smoke and dust in the sky brought up by their rapid march!

It was only at this time that Comrade Han Feng jumped up in a dashing manner, and with a few flying points on his toes, he flew onto the head of the high-level bone dragon. Then, he gave the order of strategic transfer to the junior brothers in a hurry!

As a result, the Behemoth Skeleton Knight Force, the Black Knight Force, and the Long-Range Magic Attack Force, led by the Death Knight Marcus and the high-level skeleton mage Kuru, started one after another and rushed forward!

Behind, the screams of the undead lich Usr were heard again, full of anger, unwillingness, and depression!

And because you have to die the lich Usr doesn't feel very depressed! That damn Comrade Han Feng in front of you is simply teasing and teasing it! Despite repeatedly urging the Skeleton Warrior troops to speed up their pursuit again, the undead Lich Usr was well aware that this was just a futile attempt to vent!

Want to chase the cavalry with the infantry? The undead lich Usr isn't really in the head! It's just that Comrade Han Feng's posture is clearly teasing and playing, which makes the immortal lich Usr really feel sullen!

The immortal lich Usr couldn't help but be secretly ruthless in his heart: as soon as the aid force he invited arrived, he would immediately destroy all the damn guys in front of him. Especially the hateful guy who led the way, he must detain his soul and slowly torture him for thousands of years! Otherwise, it's really hard to understand this hatred in my heart!

Not to mention the curse and oath of the undead lich Usr, as Comrade Han Feng led the younger brothers to let go of the speed of the wild run, the undead lich Usr and its skeleton warrior troops were obviously only quickly distanced! A new round of pursuit and diversion has begun again!

Another day later, Comrade Han Feng and his younger brothers, just like more than a day ago, opened up a distance of about three or four hundred miles with the army of skeleton warriors of the undead lich Usr who were chasing behind, and then began to set up camp. Comrade Han Feng once again set up a spirit gathering formation for himself and the younger brothers to absorb soul energy.

A qiē seems to have started a new cycle again. It's just that this time Comrade Han Feng obviously has a different plan than last time!

As long as the soul energy absorption this time lasts for a whole day, Comrade Han Feng will be sure to replenish the soul energy in his body to more than seventy percent. In this way, it seems that there is a possibility of a surprise attack on the army of skeleton warriors of the undead lich pursuing in the rear!

Hehe, as long as he and the high-level skeleton mage Kuru can completely contain the undead lich and the two intermediate lichs, relying on the leadership of the high-level bone dragon and the death knight Marcus, the giant beast skeleton knight unit and the black knight force will launch a surprise battle against the six thousand skeleton warrior troops with the assistance of the long-range magic attack unit, and there is still a great possibility of success!

Although the number of the army of skeleton warriors was as high as six or seven thousand, Comrade Han Feng did not think that they had the ability to block the assault of his all-cavalry fast mobile troops!

After completely destroying the high-end combat force under the command of the undead lich Usr, the strength of the high-level bone dragon and the death knight Marcus alone is not something that this skeleton warrior army can resist! What's more, there are also auxiliary attacks from ranged magic attack units in the sky!

Therefore, Comrade Han Feng firmly believes that as long as he conducts a surprise battle, he can give the skeleton warrior troops of the immortal lich Usr a fierce blow! It is estimated that if the raid can be successful, at least hundreds or thousands of skeleton warriors will be wiped out!

In that case,...... Hehe, as long as this kind of raid continues, how many more times will the undead Lich Usr and its skeletal warrior troops be able to hold out?

Hmph, dare to kill my little brother! I can't kill you! Thinking of this, Comrade Han Feng couldn't help but feel proud in his heart! I can't help but laugh out loud!

At that moment, Comrade Han Feng did not delay, and ordered the junior brothers under his command to continue to divide into two batches as they had done two days ago, and take turns to enter the Spirit Gathering Formation to absorb soul energy! He entered the center of the formation, sat down cross-legged, and absorbed the soul energy with all his might.

This time, since the time was only more than a day apart, it was impossible to perform the Three Clear Soul Technique again. Comrade Han Feng himself estimated that it would be about four days before he had the opportunity to perform the Three Clear Soul ** again!

However, Comrade Han Feng was not so disappointed. In fact, it doesn't matter, as long as you go all out to absorb your soul energy, a whole day is enough time for you to replenish the soul energy in your body to seventy or eighty percent!

However, the senior skeleton mage next to him, Kuru, didn't know this, and he didn't dare to enter the first batch to enter the Spirit Gathering Formation to absorb soul energy. It's really Kuru-san, who is afraid that the elusive Han Feng Xiao Zhengtai will suddenly pop out and play with his big head as a toy!

Therefore, the current senior skeleton mage Kuru is far away from the Spirit Gathering Formation, while using the soul fire spray gun in his hand to process the weapons of various skeleton warriors, and at the same time, he is also aiming at Comrade Han Feng in the Spirit Gathering Formation from time to time. Once there is a trace of Han Feng Xiaozhengtai's appearance, it is estimated that the senior skeleton mage Kuru will throw away the things in his hand as soon as possible and flee quickly!

Poor Kulu classmate was obviously completely tossed and scared by Han Feng Xiaozhengtai, and it is estimated that the shadow in his heart will not be able to be wiped away in a short time!
