Ling Tianyu had already begun to draw the city that had been built, and the various formations were arranged, this was not as simple as one formation, but a combination of many formations, and even interlocking together.

The formations are superimposed, and if you want to attack and defend, you must do this, and you also need to depict the runes and so on.

Ling Tianyu took the tools and drew the construction of the city, very carefully, and even drew it quickly, it could almost be said that it was done in one go, and it was completely smooth.

There are all kinds of lines, dotted lines, solid lines, and semi-dashed lines, and the paintings are lifelike.

Duan Yanran looked at the first drawing that had been painted, picked it up, wrote everything that needed to be written, and quickly sorted it out.

Ling Tianyu drew extremely carefully, this is not a matter of one or two, this is a matter of countless sheets, there are tens of thousands of places just to get out of the buffer space, you can imagine how many drawings are needed, this is definitely not a matter of hundreds.

Duan Yanran took it one by one, looked at her husband, his forehead was already covered with sweat, and he hurriedly took the wet towel on the side and wiped the sweat.

Ling Tianyu was completely immersed in his own drawing, wiping the sweat on his forehead without noticing, the movements in his hands did not stop, flowing smoothly, without a trace of pause, except for writing runes.

It took seven days for Ling Tianyu to stand up, and even his neck was stretched, and he made a crackling sound.

"Whew-"

Ling Tianyu exhaled deeply, his hands and wrists hurt, and even made a crackling sound.

"Drink some cool mint water. Duan Yanran had already prepared cold mint water, which could be refreshing.

Duan Yanran has temporarily forgotten what Hao Ling sent now, and it is understandable that as soon as she comes back, she will not have a chance to say it, and now she is even more busy day and night.

It's completely busy to the extreme.

Now I forgot about it.

"Gollum-Gollum-"

Ling Tianyu took a few big gulps of water, and suddenly that feeling of aggrieved disappeared, and it was very comfortable.

"How many are there?" Ling Tianyu looked at the drawings on a table and knew that there were quite a few drawings.

"Nineteen thousand seven hundred. Duan Yanran had already marked it, and everything that should have been written was written.

"How many more?" Duan Yanran immediately asked.

"It's estimated that there are more than 50,000 sheets. Ling Tianyu replied: "There may be more, roughly between 50,000 and 70,000 sheets, and there are mainly many formations that need to be arranged, or even connected, which is very troublesome." ”

When Duan Yanran heard her husband's words, she couldn't help frowning, it turned out to be between 50,000 and 70,000, this kind of engineering is not a rough job, it is a fine work, and it even needs not to make mistakes.

This is not something that ordinary people can do, especially if there are too many detailed designs involved in the middle, which is too troublesome.

She really admires her husband now, such high-intensity work is really torturous.

"Let's rest a little longer. Duan Yanran looked at her husband and said, "There's no need to be in such a hurry. ”

"It's fine. Ling Tianyu shook his head and continued to devote himself to the design drawings.

When Ling Tianyu painted the interior, he used different colored brushes, and even sketched them, forming a sense of space, which was very wonderful.

A table is filled with drawings, some of which are even so delicate that people can't imagine it, but they can be understood.

Duan Yanran is all marked in block letters, there are no typos, and it is very accurate.

Ling Tianyu wrote step by step, very tired, his eyes were sour now, but time was pressing, so he could only overwork.

"Mistress. The guards brought in with boiled mint water.

Duan Yanran motioned to put it down, and she could go down.

Ling Tianyu was busy, and the Great Wilderness Heavenly Saint was also busy, and it could even be said that all the manpower that could be used was used, preparing to build the city.

Stones, and even various materials are being prepared.

The Emperor Mountain side is also going on, as long as the drawings are completed, it will start at both ends immediately, after all, it has already been planned.

Now waiting is the drawing.

In addition, the construction of the city also needs to be surveyed on the spot, after all, the geology must be clear, otherwise it will collapse if it is built rashly, or even if it is not stable, it is a problem that needs to be considered.

How much mint water was drunk, Ling Tianyu didn't know, Duan Yanran finally drank it in a big gulp, there was no way, too tired, too much mental consumption.

Duan Yanran looked at the drawings that were already full of several tables, her eyes were red, and the bloodshot was even more diffuse, obviously tired.

Daughter Ling Zhihua is very well-behaved, except that she is hungry, she sleeps after eating.

Ling Tianyu was still painting.

Duan Yanran took the latest one and looked at it, and saw that it was the final one, knowing that the painting had been completed, and she was busy marking all the ones that needed to be marked.

Ling Tianyu stretched his body, rubbed his temples, and immediately put into the next job, he needed to be more precise about some details, it wouldn't take too much, and it would take only two days to get it done.

With some precision, Ling Tianyu got the final drawing, which was also the most accurate drawing.

"Give the other half to them, let the seniors come and get it, and start building it from both directions, faster. Ling Tianyu said.

Duan Yanran signaled that he knew that he had already asked people to pass it over with a secret method, and it would only take some time to come over, just take the drawings.

Everything was prepared according to the original plan, Ling Tianyu walked out of the main hall and stretched his waist, as long as the drawings were delivered, the construction could start, everything was not a problem.

To talk about the difficulty of such a big project, the difficulty lies in the amount of work, which is too large, the number of people mobilized will be a terrible number, and the number of casualties is still an unpredictable number.

Although it was not the work of a tyrant, the exertion was too great, and it was inevitable that there would be casualties while ensuring that all the food could keep up, which all needed to be considered.

It didn't take long for the Great Wilderness Heavenly Saint to come and take away the drawings.

Ling Tianyu was waiting for time, waiting for the news of the start of construction over there, as long as it moved, it would move here.

"It should be soon. Duan Yanran looked at her husband who was waiting.

Ling Tianyu could only say wait, looking at the time, he hoped that it would come now.

"It's coming. Soon, the secret method came, and Duan Yanran hurriedly pointed to an aurora in the air.

Ling Tianyu heard the transmission in the secret method and immediately gave the order to start construction.

Hundreds of millions of people were dispatched, and cultivators naturally had to be dispatched as well, and the foundation was the first to start beating.

"I just looked at the stones, they are all mined from the unmanned interface, and the quality is good. Duan Yanran said.

"That's fine. Ling Tianyu nodded and said, "I'm thinking about whether to use cement in the city." ”

"Build an ancient city wall with cement?" Duan Yanran blinked in surprise when she heard it, "Don't be kidding, husband? ”

"There is no precedent, so I will set this precedent. Ling Tianyu looked at his wife and said, "The cement is durable, and it is also more reinforced." ”
