In less than a month or two, it was dug from Mao County to Sui County.

Of course, after arriving in Suijun, the terrain has slowed down a little, due to the terrain, the more back the more it is not very easy to dig, the Gobi, there is a lot of sand, it is easy to collapse pits, pay attention to technology, some sections of the road are dug very deep, to go deep into the ground for a few meters, like a mine......

The relative degree of danger is also very large, like this kind of road section, Zi Eleven led the city defense army to personally go out, or pick a good hand with martial arts, at least a master of internal strength.

On this day, he was digging the Yinfeng Ditch, which was obviously sandy, and Zi 11 also dug nearly three or four meters underground before digging the mud and rock.

Suddenly, there was an exclamation not far ahead.

"Ouch, it's so hot!"

Zi Shiyi hurriedly rushed over, and saw a subordinate blowing his hand, and there was a big bubble on his hand, as if it had been scalded out by the high temperature.

"What's going on?"

The subordinate pointed to a round stone on the edge of the wall in front of him, "Lord Hui, this stone can't be shoveled off with a shovel, it is very strong, I tried to pull him down with my hands, but it was burned to ......."

Zi Eleven followed his gesture and looked!

It doesn't matter if you don't look at it, when you look at it, it's a shake of energy.

Holy, this, this...... Not Yan Jing?

Most people have only heard of Yan Jing, but have never seen Yan Jing, thinking that the fire is red, but in fact, it is not, Yan Jing will turn red when it encounters fire, and it is black and autumn in ordinary conditions, no different from ordinary mountain stones.

When Zi 11 still sent someone to the Liu blacksmith, he borrowed the blessing of the rice balls and saw Yanjing once.

Yan Jing is a very peculiar material, when it is hot, it is hot, and if you touch it with a cool hand, it is cold, and this subordinate is digging a tunnel and digging all over sweat, and the heat in the palm of his hand must be high, so it is strange that he touches Yan Jing with his hand and is not burned.

When Zi Eleven just dug down, he felt that it seemed to be very hot underneath, and he thought it was because of the sand, and the heat was stored underneath, so it turned out that there was a Yanjing here!

The function of Yan Jing could not be clearer when he was looking for the distribution map of Yan Jing for the crown princess.

The crown princess went out in person, and was ambushed, under the danger, only to get only a dozen pieces, it can be seen that it is rare, Zi 11 concealed the excitement in his heart, this city defense army is newly rebuilt, he is not at ease, can not let this matter go out.

So, Zi 11 said to the subordinate, "It's hard work, it doesn't matter, hurry up and wash it down with cold water, give you a vacation, you don't have to go down the tunnel for three days, just supervise the group above." ”

The subordinates are grateful.

It must be much easier for the supervision team above than for digging tunnels below.

After speaking, he ordered to the big guy: "Everyone has worked hard today, it's time to eat soon, everyone go up and rest, wait for the meal to finish and come down, the guards will stay to inspect the project......"

"Yes! Thank you Captain for your kindness. ”

Everyone stopped what they were doing and went up happily.

The guards were all brought from Kyoto, and in general, the loyalty was definitely higher.

Zi Eleven asked the guards to cover him, he personally went out to dig up Yan Jing, and dug out a piece very smoothly, and packed it in a leather bag, Zi Eleven was already at the master level, and it was easier to dig than others, as a result, the second shovel went down, "choked", and hit a solid stone again......

Endured the pounding heart, Zi Eleven successfully dug out a piece of flame crystal!

This is the nest of Yan Jing!

Zi Shiyi's subordinates sped up, the shovel flew over, and a large area of black and autumn round stones appeared in front of him, of different sizes, some fists were big, some watermelons were big, and some winter melons were big......
