"Well, there are still 350 million spiritual energy points left, I will first build a spiritual field in Blackwater City and Xuanwu County, and then slowly develop the rest!"

Xu Chen checked it, after building the city wall, there were still 350 million spiritual energy points left in the system, even if it was necessary to save some emergency use, it could be spent on building the spiritual field.

Although this is another world, there is no comprehensive management, the merit is in the present generation, and it is beneficial to Qianqiu, but Xu Chen faintly understands that doing so may enhance his luck.

Because he understands that a cultivator is the most reasonable, the unity of heaven and man, even if human beings themselves are small, but they are good at using the surrounding environment, they can also exert unexpected strength.

Moreover, the overall aura concentration in the northern region has increased, and many strong people will emerge, and when the time comes, the power of the domination skill in the system will be greatly enhanced.

"Are you sure you want to exchange it for Huàn Lingtian? This won't help you much to improve your current strength!"

The system elf pouted, a little unhappy, she couldn't figure out Xu Chen's mind at all, in her thoughts, there was enough aura, she must first improve her strength, but Xu Chen always did something that did not improve her strength in her opinion.

"Confirm the redemption!"

Xu Chen said very resolutely, he had a plan for the current strength improvement, and he only needed to fully comprehend the last two laws, that is, he would be able to be promoted to the Emperor Martial Realm.

Moreover, it was the martial arts and the runes that were promoted together, so these auras were not helpful for his strength improvement for the time being, and he wanted to comprehend the last two laws on his own.

After giving this order, he began to look for suitable places on the map to build.

"Well, the first one was built in the mountains behind Xufu. ”

Xu Chen quickly moved the map to the Junwang Mansion, then quickly zoomed in and pointed at the back mountain. "Build here!"

There, he once set up a huge spirit gathering array, which could divert the spiritual energy to each sub-array, and only those that could not be used up would escape outside.

Xu Chen's intention to do this is actually obvious. When the aura spreads, there will definitely be martial artists who will notice it, and they will either choose to join the Xu family, or choose to buy a house to live in the surrounding area.

And those who can stand out among thousands of martial artists must be those who have cultivated to be extraordinary, so that the formation of a concentration of high-level martial artists is very helpful to the stability of Xuanwu County.

Prevent these high-ranking warriors from living among those civilians, as in the event of a dispute, innocent people will surely be harmed.

Meantime. Gathering high-level martial artists, the Xu family is also easy to manage.

"Confirm the construction of the Lingtian here?"

As the prompt of the system sounded, a red circle of light flashed on the map, and the place where the circle lived was the place designated by Xu Chen's mind.

"Sure. ”

Xu Chen gave a definite order with a flat expression, as if the aura value required to build the spiritual field was flowing water, and it couldn't cause ripples in his heart at all.

"Ding Dong! deduct 10 million aura points. ”

"Ding Dong! The first-level spiritual field has been built, is it going to be upgraded?"

Hear a reminder from the system. Xu Chen looked at the spiritual field that had been built, it was a cloud of mist with spiritual energy fluctuations. Spiritual energy continued to emanate from it, and then it was drained by the Spirit Gathering Array.

"I don't know what the difference between this spiritual field and the spiritual vein?"

Xu Chen suddenly had an idea in his heart, and with the birth of this idea, an idea suddenly appeared in his mind, he knew that it was transmitted by the system elf, so he no longer resisted.

"Oh. It turns out that the spiritual field is actually a small spiritual vein, but it does not produce solid spiritual stones, but it can continuously produce spiritual energy, as if it is a field that can be planted with spiritual energy. ”

After digesting that message. Xu Chen understands the difference between Lingtian and Lingmai, the reason why it is called Lingtian is not only that the amount of spiritual energy is small, but also that it needs to be taken care of daily, just like planting crops, but Lingtian is more high-end, and it produces spiritual energy.

Xu Chen quickly found the upgrade option, and then clicked the upgrade button with his mind.

"Ding Dong! Congratulations to player Xu Chen, your Lingtian is upgraded to Level 2, and it costs a total of one million aura points, and the next upgrade requires a certain cooldown time, do you spend aura values to directly eliminate the cooldown?"

"What's the cooldown?"

Xu Chen was slightly stunned, he didn't expect that the system elf even moved this set, this is a means for game operators to make money, when playing that game, only by constantly spending props can they continue to build, which is also where the gap between RMB players and ordinary players is widened.

"A hundred years. ”

"One hundred days?

Xu Chen looked at the system elf who was smiling and counting the delicate hands, and couldn't help but gasp, it is still a first-level spiritual field, and it produces vitality, and it is also a very low-quality kind, only a spiritual field above the third level can really give birth to spiritual energy, and the quality of that spiritual energy is similar to that of the lower grade spiritual vein.

Of course, the aura generated by this spiritual field is extremely abundant, as long as daily maintenance is carried out, impurities are removed in time, and the spiritual eye is not blocked, it can be completely comparable to the speed at which the spiritual energy is produced by the medium-grade spiritual vein.

"Elf, are you sure it's a hundred years?" asked Xu Chen, with some reluctance.

"Of course! Directly eliminate the cooldown, cost a million aura points, no two prices!"

The system elf put away his palm and said angrily, obviously dissatisfied with Xu Chen's disobedience to advice.

"You, you are ruthless!" Xu Chen compromised, it seemed that his current aura value reserves could not build a spiritual field that could produce the best spiritual qi at one time.

"Player Xu Chen's cooldown time has been successfully eliminated! ”

"Player Xu Chen can continue to upgrade Lingtian!"

After Xu Chen painfully paid the aura value, the system sounded one after another.

"Confirm the upgrade!"

"If you pay, you will be rewarded, congratulations to the player Xu Chen for upgrading Lingtian to level three! ”

"Eliminate the cooldown!"

"Player Xu Chen has successfully eliminated the cooldown! Deduct 10 million aura points!"

"Confirm the upgrade!"

"If you pay, you will be rewarded, congratulations to the player Xu Chen for upgrading Lingtian to level four! ”

"Eliminate the cooldown!"

"Player Xu Chen has successfully eliminated the cooldown! Deduct 100 million aura points!"

"Confirm the upgrade!"

"If you pay for it, you will be rewarded, congratulations to the player Xu Chen for upgrading Lingtian to level five! ”

With one breath, Xu Chen directly upgraded the spiritual field to level five, and then took a look at the spiritual energy consumed in the system, a total of 125 million!

"Alas, it seems that my brother is still a poor man!"

Looking at this shocking number, Xu Chen felt for the first time that it seemed that with those potential 'aura values', he was still not a rich person.

Just if you want to build the entire Northern Regions into a place full of spiritual energy, you need to be in debt.

And this number may reach trillions, or even tens of trillions!

"Once it's a flower, twice it's also a flower, just go as originally planned, and build a spiritual field in Blackwater City!"

Maybe it's because the aura value is too much and it doesn't hurt, and the aura value of more than 120 million yuan is directly emptied, which makes Xu Chen a little numb. (To be continued......)
