Zhao Cheng's contemptuous face turned white in an instant, the city wall that the spirit burned was the most stable section, it was impossible for ordinary people to insert the halberd into it, Zhao Cheng couldn't figure out how to destroy a wall with two halberds.

"Is the Mo family's technology advanced to this point?" Ziying sighed secretly, there are indeed a few points in the structure of the house, and it can be touched and the whole house can be destroyed, but this is how the Mo family found out thousands of years ago.

"Now has the contemptible people been approved by King Qin?" Ling Yan smiled, and the guards beside him slowly moved away from Ling Yan.

Ziying came to his senses, stepped forward, pushed away the guards in front of him, and bent down towards Lingyan, "Boy, please give me advice!" ”

With Ling Yan's skills, if you want to kill him, you don't need to pick time at all, just because of the Mo family's exquisite tricks, you can be worshiped as a guest wherever you go.

Now that Lingyan can take the initiative to return, Ziying doesn't know what Lingyan thinks, but he must not be lazy.

Ling Yan smiled and helped the child up, "King Qin can't be so generous, the contemptible can't afford it." ”

"Sir, you can bear it." Ziying's tone was resolute.

Ling Yan's eyes were full of the elders' concern for the juniors, "Since this is the case, then King Qin can be regarded as a contemptible apprentice." ”

"Widow... The disciple will be named Mr. Taifu tomorrow. "The widow is used to being called, and the child almost didn't change.

"It's good that King Qin has this heart, the Mo family is still simple, and he doesn't care about any official position." Lingyan refused.

Ziying smiled and said, "That disciple also learns from Xiang Yu and calls you a father." ”

"King Qin is polite, just call the master."

"Dead boy, his face is changing pretty fast." Ziying and Lingyan talked very happily, Cai Wei was secretly jealous in her heart, she was originally the only apprentice of Lingyan, but now Ziying came to grab the position.

Cai Wei was still not sure if Ziying was the Lu family, and Zhao Cheng, who killed Gai Nie, was also standing beside him.

A thought was formed in Cai Wei's mind, and Ling Yan became Ziying's teacher, wouldn't Ziying listen to him everywhere in the future.

Seem... This is an opportunity for revenge in the future.

Cai Wei's eyes gradually sharpened.

After a laughing conversation, Ziying entered the carriage with Lingyan.

"The first emperor took mountains and rivers as the city defense, and never refined the Xianyang city wall, and this is the first contemptible." Lingyan sighed.

Ziying was a little embarrassed, "Master, in fact, this time it's not a repair, it's a reconstruction." ”

What Great Qin has lost is not only the land, but also the hearts of the people, except for the Qin people, everyone in the world hates Great Qin to the core.

Ziying needs to have a stable nest in the Chongshan Pass, so that he can have a chance to defend against Liu Xiang's attack and have a chance to counterattack.

"It's okay to rebuild, but Liu Bang is just outside the pass, and I don't know when he can attack it, will it be too hasty." Ling Yan was uneasy in his heart, "King Qin wouldn't want to be like the First Emperor and launch hundreds of thousands of conscriptions, right?" ”

"Don't worry, master, absolutely not, I will give them money." Ziying hurriedly explained that he didn't dare to do anything that was unpopular with the people.

Lingyan nodded thoughtfully.

The carriage came to the dormitory without hurrying, and the child and the spirit burned and knelt opposite each other.

"Everything tomorrow is up to Master Lao." Ziying said respectfully.

"When does King Qin plan to complete it at the latest?" Lingyan asked.

The walls of the Qin Dynasty were made of rammed soil, and at most some stones were laid on the outside. Lingyan has other ways to be a giant of the Mo family, if Ziying can really have a lot of manpower, Lingyan will choose the best method for him according to time.

"It's tomorrow." Ziying replied.

"Is King Qin serious?" The spirit was stunned, even the simplest tamping of the soil could not be completed in a day, it must take many days to compact, and if the soil was not solid, the brutal overseer would directly lay the person in charge of that section of the city wall to death.

This Master of King Qin is really not something that ordinary people can do.

Ziying also knew that this task was too difficult, but there was an optimal way in his heart, and he didn't know if Lingyan could understand it.

Although the Qin Dynasty already had iron smelting technology, it was not mature at all, and that method might not work at all.

"If it really can't, then the sooner the master wishes, the better." Ziying sighed and said, "Tomorrow I will go to Kunguan in person to buy enough time for the master." ”

Liu Bang will follow the old method, first buy the soldiers who defend the city, let them relax their vigilance, and attack the city when they are unprepared.

If Ziying went to the town in person, the soldiers would definitely not be careless, and with the easy-to-defend and difficult-to-attack terrain of the pass, Liu Bang and they would definitely not be able to attack it.

"King Qin doesn't have to sigh, tomorrow the contemptible people will crush the rocks on the surrounding mountains into foam, add clay and water, and put them into a wooden model, this method only needs one day to form, but unfortunately it needs to be watered for about 10 days before it can be officially used." Lingyan said that it was already the strongest way he could think of.

"Okay, then..."

Ziying was stunned, he had heard this method, not in the Qin Dynasty, but in modern times.

Isn't that the concrete he had in mind?

Lingyan actually understands this!

Ziying was both shocked and excited, "Master, haven't you thought about adding iron tools to the model again?" That would make the walls stronger. ”

Ling Yan thought slightly and shook his head, "The iron tool is rigid and easy to break, and when the iron tool is broken, the city wall will be scrapped, and steel with excellent toughness should be used!" ”

"Steel ....."

Ziying was dumbfounded and had nothing to say, this giant was a little magical. When iron smelting was not developed, Lingyan could actually understand what steel was.

In ancient times, there were indeed many things that did not seem to belong to this era, and the bronze sword of King Goujian of Yue was immortal for thousands of years, and it was impossible to make a second one in that era when it was excavated.

However, the impact of the spirit burning on the child is too great, could it be that the spirit burning also crossed over?

Ziying decided to give it a try.

"Alas, it's really inconvenient to have no electricity, otherwise you wouldn't have to light an oil lamp at night with Master." Ziying finished speaking casually, staring closely at Lingyan's reaction.

Ling Yan frowned tightly, extremely puzzled, "Is King Qin talking about the thunder and lightning in the sky?" If you want the light of thunder and lightning on a rainy day at night, it is better to use an oil lamp. ”

Ziying breathed a sigh of relief, it seems that Lingyan is just a Mo family giant.

Suddenly, Ling Yan fell into deep thought, "According to the essence of Yi, the heavens and the earth are interrelated, and perhaps there are things similar to thunder and lightning in the whole world, and the contemptible may really be able to find them. ”

"Master, let's talk about tomorrow's city wall." Ziying hurriedly stopped Lingyan's thoughts, if Lingyan really went to study electricity, no one would build the city wall.

"It's okay, this is the top priority of the Qin State." Ling Yan retracted his thoughts, he didn't know what he had almost done at that moment.
