Tianhuo didn't know that when he entrusted the Nineteenth Prince to summon him, Xuanjizi had already rushed to rescue Ah Li.

The news did not come back for a long time, and Tianhuo could only build an underground teleportation array by himself.

In order to prevent the underground ore deposit from collapsing and burying the teleportation array, Skyfire decided to build the teleportation array inside a sturdy house.

At first, Tianhuo wanted to transport the materials underground and build houses directly on the mine deposit, but the head of the craftsmen objected, he used to be a master craftsman in the Ministry of Works, and he was very prestigious in the construction industry, and he said that if he didn't work, no workers would go to the mines.

Later, Tianhuo proposed to build a strong house on the ground and put it in a storage magic weapon to take it down to be placed, so as to avoid the pain of transportation and the workers were not in danger, and this plan was supported by the master craftsmen.

Tianhuo and Dasaku took people down to measure the size of the house, and designed a house that was one zhang tall and two zhang square, which was enough space to build a teleportation array.

The biggest storage magic weapon on Tianhuo's body can put down things that are three zhang square, and you only need to move out a part of the things inside, and you can directly fit this house into it.

The house was made of copper frame wood, and Daisaku designed it himself, and the craftsmen quickly got busy.

The problem of the house is solved, as well as the problem of the collapse of the mine, the tailings deposit is 300 zhang deep underground, and the mine is more than 800 zhang long, so it is common for the mine to collapse.

In the early stage, the columns in the mine have been partially damaged because they have not been replaced for more than ten years, and only more than 600 zhang of the mine have columns, and the amount of reinforcement is huge.

For the time being, the Nineteenth Prince has no manpower to send to support Tianhuo, so Tianhuo can only find a way to solve it by himself.

After that, Tianhuo was in the underground longer than on the ground, and he first tried to strengthen the mine with soil attribute exercises, but unfortunately he could only temporarily strengthen the surface of the cave wall of the mine road, which would soon crack and peel off, and the reinforcement effect was poor.

Tianhuo also tried to cultivate mutant earthworms to improve the quality of the soil near the mine and improve the adhesion effect of the soil, but unfortunately he did not learn the way to control beasts, and there were not many ways to cultivate earthworms, which were lower animals.

Under the stimulation of pills and spirit stones, several large earthworms seven or eight feet long were generated, which did not help to strengthen the mine in the slightest except to scare people in the mine.

Until one day, Tianhuo found a vine plant in an abandoned mine, this vine plant is shady and tough, covering the inner walls of the mine.

Its roots are so well developed that they sink deep into the walls and lock in the gravel soil, so the long-abandoned mine has never collapsed.

However, this kind of vine only grows in that one mine, and somehow it does not spread outward, and Tianhuo studied it for two days before discovering that the vine in the entire mine belongs to a single plant, not divided, and its growth limit is only so large.

He was very excited about the discovery that some of the vines with roots cut off by Tianhuo and transplanted them into other mines, and he immediately calculated the number of branches needed and the location of transplanting points in the mine according to the area of the entire mine.

Once all the points have been marked by the fire, the rest of the work is left to the workers.

At this time, the teleportation array secret room arranged by Tianhuo had also been built, although it was just an ordinary wooden house, but before installing the roof of the teleportation array secret room, the craftsmen and masters asked Tianhuo to personally go up to the beam according to the old rules, in order to be auspicious.

Tianhuo did not refuse, and he personally placed a bowl-thick iron pear wood beam on the wall that had been built.

After a burst of firecrackers and gongs and drums, the craftsmen quickly lifted the roof that had already been made and buckled it to the four walls.

The workers set up the ladder and went up to jingle and knock, and soon the installation was completed, and the whole house was made of wood except for the four corner columns made of copper pipes, and the roof and the roof were now mortised and tenoned.

The house is not only sturdy but also beautiful, although this kind of boxy house does not have much room for craftsmen to play, but the craftsmen still insist on making different fancy patterns on the feet and eaves, and carving all kinds of complex patterns on the walls.

It has to be said that the Song Kingdom is the most aesthetic tradition among the three Chinese countries, and it far surpasses the Tang and Ming kingdoms in the north in terms of the fineness of life, which can be seen from the shape of a wooden house.

The moire patterns on the outer wall of the wooden house were all carved by Dazuo himself, and he patted his chest and said: "Young Master Tian, don't look at this room is wooden, but with these moire, I dare to guarantee that it can remain deformed for five hundred years even in the damp underground." ”

Tianhuo had already noticed the extraordinaryness of these moires, and couldn't help but reach out to touch those lines, and it took Tianhuo for a long time to figure out that these complex moires actually had the effect of avoiding water and drying.

This masterpiece is clearly not a monk, but he has such skills, and it seems that most of them are family hand-me-downs, and although the descendants do not know the principle, they can copy it completely, which makes them infinitely useful.

Tianhuo patted Dazuo on the shoulder and said: "Master Dazuo, your craft is absolutely genuine, don't let it be lost, in the southern region, your children and grandchildren can always be rich with this craft." ”

Dazuo heard that Tianhuo was praising him, and he grinned non-stop, a noble person as wise as a celestial man like Young Master Tian could praise himself, which was enough for him to blow in front of his children and grandchildren for many years.

The next house installation is simple, Tianhuo directly puts the finished teleportation array wooden house into the storage magic weapon, and takes it out after going down to the ore deposit.

After the house was placed, Tianhuo also had to admire the craftsmanship of the craftsmen in Jinling, the size of the wooden house did not have a single error, it was tightly embedded on the ore deposit, and several contacts at the bottom of the wooden house and the ore deposit did not need to be adjusted, and the teleportation array was immediately activated.

The heavenly fire drilled into the wooden house, the wooden house was very bright, and the spiritual energy lamp developed by the Xuanji faction emitted a soft light, and only a very small amount of spiritual energy was needed to make the lamp light on for a long time, not to mention that the spiritual energy here was so abundant.

Tianhuo opened a dark grid in the middle of the teleportation array on the floor, took out a fist-sized positioning stone, solemnly placed it into the dark grid, and then covered the cover.

Tianhuo took a deep breath and continuously clicked on the gossip points of the teleportation array, the sequence was extremely complex and irregular, and after clicking sixty-four times in a row, he only heard a soft sound of "po~", and the positioning stone in the dark grid emitted a strong light, driving the entire teleportation array to light up.

After a spatial fluctuation that was not very strong, the teleportation array slowly dimmed, but the entire teleportation array was like a life, with ambilight fluctuating on it, showing its connection with the distance.

With the positioning stone and the teleportation array, plus the sixty-four-bit cipher code is successfully matched, the teleportation array of the Tu is successfully activated, and it can pass things to each other with the teleportation array in the Xuanji Cave.

Tianhuo took out a letter and put it on the teleportation array with a little excitement, and gently activated the switch, and the air in front of him fluctuated, and the letter disappeared.

Being able to send the message out means that the teleportation array is half successful, and now it is just waiting for the other party to reply to determine whether the teleportation array is connected in both directions.

After waiting for more than an hour, Tianhuo was bored thinking about how to continue to transform the Dangtu base, when suddenly the teleportation array lit up, and the space was distorted again.

Seeing that there were seven more bottles and cans on the teleportation array, but there was no letter, Tianhuo hurriedly opened the bottle to find it, and after opening the third bottle, he pulled out a note from it.

"Senior brother, the letter has been received, but unfortunately the road is too far, the teleportation array can only transmit things within seven catties at a time, and it cannot be transmitted in both directions more than three times a day, otherwise the teleportation array will be damaged or items will be lost.

In addition, Master has already brought the sixth, ninth, and tenth juniors to Jinling, and you will be able to meet in a few days. --Tie Yumo"

Tianhuo put away those new medicines with satisfaction, and prepared to reply to the senior brother to ask for the elixir, and some of the drugs in the Xuanji branch were insufficient and needed to be replenished urgently.

Tianhuo took out Supa and charcoal, and hurriedly wrote a reply to the senior brother, the first letter was only an experimental nature, for fear that the transmission mistake would fall into the hands of others, Tianhuo did not write much content.

In this letter, Tianhuo introduced the recent situation in detail, including the relationship between the Xuanji Branch, the Dangtu base and the Nineteen Princes, etc., and also attached the list of pills needed in the near future.

Tianhuo carefully read the letterhead, and after not missing it, he sent the letter away.

Only three teleportation opportunities a day are a headache for Tianhuo, and the teleportation array can't teleport storage bags, and after the two spatial magic weapons are superimposed, it will cause the space to collapse one hundred percent.

It seems that we have to hurry up and let the Tu workshop operate, but unfortunately there is too little manpower, I don't know when the master and they will be able to arrive, if the three senior brothers can come, the manpower of the Tu base and the Xuanji branch of Jinling City will be enough, and then they can do a big job.

Thinking of this, Tianhuo immediately came to his senses and prepared to go up and urge the workers to speed up the construction of the workshop.

Tianhuo came to the ground in a happy mood, and immediately found that something was wrong, and the workers who usually worked hard were all absent-minded, and their eyes glanced in the direction of the station from time to time, and they saw that there were a few more strong and good horses there.

Tianhuo grabbed Dazuo and asked: "Dazuo, what's wrong? Why are everyone slacking off?" ”

Dazuo lowered his voice and said: "Young Master Tian, the palace sent someone to summon you, I don't know if it's a blessing or a curse, you should be more careful." ”

After finishing speaking, he hurriedly walked away, he used to work in the Ministry of Industry for more than 20 years, built mansions for countless dignitaries, and the high-ranking officials who were still holy and righteous the day before, and were pulled to behead a lot the next morning.

Although Young Master Tian is a friend of the Nineteenth Prince, if he offends the emperor, it will still be a dead end, if it is not for the fact that Young Master Tian is a good person, Dazuo will not take the risk of reminding him.

Tianhuo didn't know why someone from the palace came to look for him, so he could only go over and have a look first.

As soon as Tianhuo entered the room, he saw a white-faced and beardless young man in his twenties sitting on a chair, and four guards with knives stood on his left and right.

Tianhuo hurriedly stepped forward and clenched his fists: "Lord Zhongguan, student Tianhuo doesn't know that you are coming, it's too late to greet you, and I hope you will atone for your sins." ”

After the young man looked Tianhuo up and down, he said softly: "You are Tianhuo, sure enough, you are a talent, the ancestor asked me to invite you, I didn't say that I wanted to arrest you, you don't have to be nervous." ”

"Dare to ask the ancestor who is the big man, do the students recognize it, and what is the matter with summoning the students?"

The young man got up and said, "The old ancestor is the old ancestor, you will know when you go." Tianhuo, your atmosphere is here, the emperor wants to see you, come with us. ”
