(Note: The chapter number of the previous chapter is repeated, it should be 158)

In the planning, the new Chang'an was directly designed to the outside of the Fifth Ring Road.

In order to facilitate the relocation, of course, it is impossible for the people of the whole city to leave the city first and wait for those who are dragging their families and belongings, and they have to make some preparation time for others to move.

So when the construction started, it was decided to build from the outside in.

First build the city wall outside the Fifth Ring Road, and then build the "Fuxi Congenital Sixty-four Hexagram Area" and the "Bagua Area" of the Fourth Ring Road inside the Fifth Ring Road.

In this way, after the completion of the construction of the four artificial reservoirs in the "Sixiang District" of the Third Ring Road and the landscape forest in the city, there is no need to move the buildings in the original Chang'an City.

It is completely possible to wait for the people in the city to move out, and then start the construction of the "Liangyi District" of the Second Ring Road and the "Taiji District" in the center, so as to avoid disturbing the people and causing chaos as much as possible.

However, even Bai Yuqi borrowed the "arcane fire" left on the "Divine Bull Stone" to increase the concentration of [arcane particles] in the space around his body.

And with the passage of time, the concentration of [Arcanon particles] in the Chang'an area has also increased slightly, but it is also an impossible task for Bai Yuqi to build a city wall that surrounds an area of thousands of square kilometers in one form.

Therefore, Bai Yuqi had to use the power of 100,000 disciples of the craftsman clan to jointly cast spells through the connection between the system and the subsystem.

Although the "cultivation" of the 100,000 craftsmen is weak, and not all of them have learned the "Five Elements of Building the Method, the Book of Earth", but they can't resist the number of them!

Even if you practice to level 4 on average, you can control 400 cubic meters of earth and stone per person, and 100,000 people can control 40 million cubic meters of earth and stone, which is much more powerful than Bai Yuqi fighting alone.

As for those artisan disciples who don't know the "Earth Scripture", Bai Yuqi can use the effect of [Skill Sharing] to let them temporarily master the corresponding spells.

In fact, to put it bluntly, the role of these disciples is mainly to expand Bai Yuqi's casting range and casting distance, and to exist as a mana output point.

However, as the towering city wall formed in one piece rose from the ground, radiating in an arc along the 3D modeling formed in Bai Yuqi's mind, his mana of nearly 4 million burned wildly, so much so that a white flame of light was formed around him, which was a sign that the natural energy drawn by mana began to riot!

If this continues, let alone complete a whole circle of walls, not even a tenth of the distance!

Sensing that his mana was about to be exhausted, Bai Yuqi opened his eyes regretfully, it seemed that he could not achieve the effect of "raising the city from the ground between waving his hands".

You can only stop [meditate] and replenish your mana before you start building in stages.

Although the current effect is also spectacular, it is still not comparable to the shock of a single molding.

Faith is a bit similar to morale, if you can't achieve the best shock effect at one time, the amount of faith generated for the second and third time will drop by a diving margin.

But fortunately, in order to watch the ceremony, most of the people of Chang'an gathered next to Weishui, and he built the city wall from Weishui as a starting point, so that the people could only see this side.

When the walls spread out of their sight, they couldn't actually tell how far they had built, so the amount of faith they contributed was huge.

But just when Bai Yuqi was about to interrupt the effect of the spell, the system suddenly projected a reminder: [The Faith Quota and Soul Energy Quota have reached their peak, are they promoted?]

Bai Yuqi was stunned, he was actually promoted at this time?

You must know that he had already raised himself to [Level 0 and Level 20] by slaughtering bamboo rats before.

Later, he absorbed more than 43 million soul energy from Qu Tutong and more than 69 million soul energy from Qin Qiong, and the total amount of soul energy accumulated in the soul energy pool had exceeded the 100 million mark.

But it's still stuck in the level of [0 level 20] and can't be improved, but I didn't expect that it would take the belief amount to accumulate to 100 million before it can activate the promotion.

"Advance! Advance!"

Bai Yuqi, who felt that he was one step closer to his way home, was overjoyed.

I saw that the soul energy and faith in his body gradually began to merge together, so that the milky white light representing faith and the rainbow light representing soul energy flashed on the surface of his body, illuminating the entire sky with a brilliant contrast!

Only to feel that the cells in his whole body seemed to be "burning" as if they were ignited, Bai Yuqi involuntarily snorted, but he felt that his mana value began to climb wildly, and he endured the discomfort when he was promoted, and poured the skyrocketing mana into the spell that was maintained!

Originally, because Bai Yuqi and the disciples of the craftsman clan had exhausted their mana, the city wall, which had gradually stagnated and stopped growing, soared like a whipped war horse, and sprung up like mushrooms after a rain in the furious roar, forming and solidifying it step by step.

[Host, do you want to take an adventure?]

Just as Bai Yuqi was struggling to maintain the spell and the architectural model in his mind, the system suddenly projected a line of extremely tempting handwriting in front of his eyes.

"Adventure?"

While enduring a strong burning sensation of cells and some inexplicable change in his body, Bai Yuqi responded inexplicably: "What do you mean?"

[Do you see the 'arcane fire' in your hand?]

The system tempted with an evil tone like a demon's whisper: "Drain it!]

"Less nonsense! What is the benefit of directly talking about absorbing the arcane fire!"

Bai Yuqi, who felt that his internal organs were beginning to turn over, said angrily: "Also, what the hell is this advancement, why is it so uncomfortable?"

[Aren't you suffering from the thin concentration of [Arcane Particles] and being trapped in the Zhongnan Mountain and Chang'an area?]

[The mana consumed by you to release the spell is actually the energy that is refined and transformed by absorbing the [Arcanon Particles] and fusing them with your own biological energy. 】

[If this 'arcane fire' is absorbed into the body, it is equivalent to colonizing a 'fire' that continuously produces [arcane particles] into itself.] 】

[At that time, the [Arcanon Particles] generated by the 'Tinder' will be directly used by you, saving a procedure of absorbing [Arcanon Particles] from the outside world through [Meditation]. 】

[In this way, you can be exempted from the restrictions of the arcane energy environment, even in the 'arcane vacuum' environment, you don't have to worry about running out of mana!]

"You said it as if you didn't say it!"

Although the system said it was tempting, Bai Yuqi was not fooled and said: "What is the danger of absorbing the Arcane Fire?"

[If you want to become stronger, of course, you have to bear a certain amount of risk. 】

[Whether or not you can successfully absorb and fuse the arcane fire depends on whether you can withstand this high-energy substance yourself.] 】

[If the fusion is successful, it will naturally be a tender model of the club, but if it fails...... BOOM！】
