“......”

After the consternation, there is excitement.

Meng Chen did not immediately reply to Chen Manqing, but directly sent the entire "Dan Dao True Explanation" to Chen Manqing.

With his current mental power, sending such a book is a matter of blink of an eye.

And Chen Manqing, on his side, also immediately accepted the classics.

"This ...... Meng Chen, this way of purification is so magical......

After about a cup of tea, Chen Manqing excitedly sent a message again.

Obviously, after he received the true solution of the Dan Dao, he immediately noticed the "Purification Dao" in it, and discovered that this book had extremely great prospects for the barbarians!

"Well, without further ado, you should immediately find someone to transcribe all the methods of the path of purification, and then immediately choose a reliable and talented clan from within the barbarians to start studying. ”

Meng Chen said with a smile.

With this Dan Dao true explanation, the development bottleneck that Chen Manqing is currently facing will be solved soon.

In fact, in the past few decades, Chen Manqing has basically developed the development space of the Chihong Barbarian Department to the extreme.

Today's "Qingchen City" has grown to more than 100. With Meng Chen's various support and Chen Manqing's unremitting efforts, the other three barbarian tribes around the Chihong Ministry have all been incorporated into the territory of the Chihong Barbarian Tribe, and the Dizhou and other countries on the border of Zhongzhou have also bowed down to the Chihong Ministry.

As early as a few years after Meng Chen set foot in the universe, the old barbarian king had also officially passed the position of the barbarian king to the ninety-ninth son, the ninety-ninth man, that is, Chen Manqing.

In terms of strength, with the assistance of the massive resources from various worlds provided by Meng Chen, Chen Manqing had also reached the strength of the peak of the Blood Exchange Realm.

Moreover, because he had cultivated a large number of various otherworldly powerful body refining methods provided by Meng Chen, Chen Manqing's combat power had also become recognized as the number one in the Red Rainbow Division!

However, because the barbarians are inherently unable to practice qi, they face a great bottleneck in expanding their territory. Because even if it is as strong as the Barbarian Blood Realm, it is not able to fly autonomously, and in the case of long-distance running, it can only use powerful birds to travel.

And the barbarians are naturally huge, and there are very few birds that can carry them. In this case, the speed of external expansion will naturally be greatly limited.

According to the solution that Meng Chen discussed with Chen Manqing before, it was to purchase several batches of spacecraft from within the main world of the earth to solve this problem.

However, although the barbarians are physically strong, they generally have low intelligence, and they cannot use the flying machines that can be controlled by mana, and the pure technology flying machines require a lot of learning and practice to be truly able to control them freely.

So far, the 500 trainer planes and 500 fighters that Meng Chen sent to the barbarian department in the past not only failed to form much combat power, but crashed more than 80 ships due to improper operation, and the members of the barbarian department who participated in flight learning and ground support personnel also lost thousands of people......

Up to now, the strong men of the barbarian department, who are five big and three thick, even avoid these huge "technological monsters", and talk about "flying".

In this regard, Meng Chen and Chen Manqing were also a little helpless. After all, before Meng Chen came to the aid of the barbarians, these barbarian giants were still in the stage of living in stone houses and even eating raw meat. Trying to make the barbarian tribe rise from the barbarian era to a technological civilization at once is an almost impossible task in itself.

But with this book of purification, the situation is completely different. The five-series Void Pill Fire itself is also a kind of energy, as long as it is cultivated, then it can not only be used to purify the pill, but also according to this energy attribute, the corresponding flying magic weapon can be used, and even according to this energy attribute, special flying machines can be customized.

In this way, the bottleneck of development that plagued the barbarian department will be solved soon.

As for Meng Chen, after the Barbarian Department cultivated a large number of alchemists with the Five Lines of Void Pill Fire, he could buy batches of commonly used ordinary pills in the universe or other worlds under his control, and send them to the Barbarian Ancient World for purification, so that they could become medium-grade, high-grade, or even top-grade pills.

You must know that the price difference between the vast majority of Dan grades is very large, and there is generally a price difference of 30%, 50%, or even 1 time between general and medium products. The gap between the general product and the top product will generally reach several times, or even ten times the difference.

As for the gap between the general and the best, that's not to mention. The gap between some pills and the best can even reach an astonishing hundreds of times!

......

After that, Meng Chen and Chen Manqing chatted for more than half an hour, and roughly made arrangements for the development of the barbarian department in the future, as well as the feedback effect on the main world of the earth.

The mind withdrew from the spirit interface, and Meng Chen activated the power of the Void to hide himself, flickering towards the outside of the Dao Domain Dan City.

With this retreat, he immediately felt another difference in the world of immortals.

Here, too, the power of the retreat is limited.

This may be the rules of heaven and earth, or it may be the power of the ubiquitous treasure "Time and Space Forbidden Lock" above the immortal mound, or both.

Leaving Daoyu Dan City, Meng Chen continued to flicker northward.

......

Soon, a "black line" that almost connected the sky and the earth was not far ahead.

The Gorge of the Two Realms!

Inside the immortal mound, the dividing canyon that divides the human race area and the reckless demon land area.

The north of the Gorge of the Two Realms belongs to the area controlled by the Terrans. And the area south of the Two Realms Gorge, which spreads for thousands of miles, is the reckless demon land controlled by the demon clan.

"Huh!"

Meng Chen's body flashed, and he had already flown to the sky above the Two Realms Gorge, looking down.

Overlooking it, the two gorges spread endlessly from east to west, about dozens of miles wide from north to south, and on both sides of the canyon, there are also straight and tall black trees.

These black trees are the alien "ironwood" that grew out of the surrounding area of the Two Realms Gorge by the erosion of the alien "evil qi". ”

The divine sense swept around the Iron Wood Forest several times, and Meng Chen couldn't help but look at the east and west sides of the endless Two Realms Gorge.

In fact, he didn't need to look at him to know that with his eyesight and divine sense, it was completely impossible to see the end of the Two Realms Gorge.

Because this two-realm gorge is dozens of miles wide, the length of the east and west is millions of miles, almost traversing most of the Immortal Mound Continent!

And in the legend of the immortal mound, this canyon that is millions of miles long was actually caused by the aftermath of a sword qi that fell from the sky more than 100,000 years ago!

"The aftermath of a single sword qi slashed through millions of miles, dividing the Terran region and the reckless demon land in two...... What a great power this is, what a sword?"

Meng Chen couldn't help muttering in his heart.

"More than 100,000 years ago...... Sword ...... Could it be it?"

After sensing for a moment, Meng Chen couldn't help it, and turned his gaze to the northwest direction of the Two Realms Gorge, looking at each other from a distance.
