"My lord, it's not good. The soldiers from the imperial court are here. They said they were following the emperor's instructions and came to train with Yan Bei's army." The soldier ran up to Xiao Jiu'an panting, and before he could catch his breath, he hurriedly
said.
"Training together? What a good excuse." After hearing this, Xiao Jiuan smiled coldly, and a coldness flashed through his light eyes.
He brought the Yanbei Army to the mountains under the guise of training. The emperor sent people to monitor the Yanbei Army in the name of training together. This reason was so reasonable that no one could refuse.
Of course, Xiao Jiuan did not intend to refuse: "Let's go and meet the soldiers and horses of the court for a while."
Xiao Jiu'an dusted off the remaining dust on his sleeves and walked forward with a calm face. After taking two steps, he stopped again as if he thought of something, turned around and said to Ji Yun: "Use all these explosives."
Far away, leaving no one behind."
The lethality of these earthen explosives was so astonishing that he could not take the risk of leaving them, let alone let anyone in the court see them. If they fell into the hands of others, it would bring huge trouble to him and the Yanbei Army.
"I know, I will use it up as soon as possible." Ji Yunkai nodded lightly, indicating that he understood.
Yan Beijun betrayed Xiao Jiuan once, but Xiao Jiuan does not trust Yan Beijun as much now as before.
"Yeah." Xiao Jiuan nodded with satisfaction.
He just likes Ji Yunkai's intelligence and practical knowledge. Ji Yunkai is the most compatible person he has gotten along with so far. Even Xiao Zirong has to take a step back.
After Xiao Jiuan finished explaining, he took people to meet with the soldiers and horses of the imperial court, and left all the affairs of the mine to Ji Yunkai.
Xiao Jiuan's attitude is very clear. He will be responsible for solving the problems of the court. Ji Yunkai and Feng Qi are responsible for solving the problems in the mine. He doesn't care what method is used, he only wants the results.
Ji Yunkai did not rush to bring explosives into the mine. Instead, he asked people to measure the area of the explosion, the distance the gravel flew, and the depth to which the stones were blown apart.
After measuring these data, Ji Yunkai found an open space, broke off a branch, and calculated the maximum load-bearing capacity of the mine on the ground.
"What is this?" Feng Qi stepped forward and saw that Ji Yunkai had written a series of symbols on the ground that he could not understand, and couldn't help but ask.
He suddenly discovered that Yun Kai had many secrets and many things that he could not understand.
"Calculate the power of the explosives and how much explosives we need to use to ensure that we can blow up the boulders without causing the mine tunnel to collapse." Ji Yunkai did not look back and continued to calculate.
She knew that Feng Qi wouldn't ask any more questions.
Feng Qi is such a considerate person, he can even accept her powers without any care. Is there anything else about her that Feng Qi can't accept?
Sure enough, Feng Qi didn't ask any more questions after hearing this. He just stood aside silently, blocking others from approaching for Ji Yunkai.
He knows that Yun Kai has a secret, but it doesn't matter, he will protect her secret with her.
Ji Yunkai calculated it once and checked it again. After confirming that there was no problem, he erased all the numbers on the ground.
Just to be on the safe side, she scraped it with stone chips to make sure no one could see anything strange.
"Brother, I've done the math. Let's blow it up first, using four explosives, and then we'll see what happens next." According to her calculations, the explosives she brought were enough, of course, provided that the stone was blocking the way inside the mine.
The stone in front of them is really a stone, not a mountain of rocks.
If it were a rocky mountain, that little explosive wouldn't be enough.
"Okay." Feng Qi stepped forward, took out four explosives, followed Ji Yunkai into the mine, and placed the explosives according to Ji Yunkai's request.
"Yunkai, you go out first, and I'll make some leads." He didn't argue outdoors before because he knew it was safe outdoors, but it was different in the mine.
Ji Yunkai did not refuse. She knew that Feng Qi knew martial arts and could run faster than her.
"Brother, you must go out immediately after lighting the fuse. Remember, the sooner the better. Don't stop after you go out. The further away from the mine, the better. Although I have calculated it, I cannot guarantee whether there will be any errors in the calculation. In case of a mine,
If the cave collapses, it will be dangerous." For the sake of safety, Ji Yunkai warned Feng Qi in detail, and Ji Yunkai didn't go out until Feng Qi repeatedly assured him.
After leaving the mine and walking far away, Ji Yunkai shouted: "Senior brother, it's okay."
In the mine, Feng Qi heard the sound and blew on the fire. He stepped forward and ignited the twisted fuses.
After lighting the fuse, Feng Qi was not in a hurry to go out. Instead, he ran out only after confirming that the fuse was burning normally.
It's not necessarily true that he was running. Feng Qi didn't run wildly. His speed was very fast, but his posture was as light and calm as ever, without any trace of panic or eagerness.
"Boohoo..." The fuse was burning, and Feng Qi floated out of the mine tunnel.
Ji Yunkai stood outside the mine tunnel, looking nervously at the entrance of the cave, fearing that Feng Qi would not be able to appear in time. When he saw Feng Qi's figure appearing at the entrance of the cave, Ji Yunkai's heart dropped.
Just come out!
After Feng Qi came out, according to Ji Yunkai's words, he did not stop. Instead, he raised his energy, exerted his Qing Gong to the maximum, and flew to Ji Yunkai's face as fast as possible.
And just when he landed in a safe zone, the explosives in the mine exploded!
"Rumble..." It was like a cow turning over or a mountain collapsing. The sound was so loud that it hurt people's eardrums. The mine seemed to be shaking, and the ground underfoot also shook.
Ji Yunkai covered his ears and stepped back, looking at the gravel and soil flying out of the mine tunnel with a solemn expression.
The power of the explosion was more serious than she expected, beyond her estimation. She wondered if the mine tunnel could hold up?
There was only one explosion, but the earthquake sound lasted for a long time. After the explosion, no gravel flew out of the mine tunnel, but dust continued to pour out.
However, thankfully, the mine tunnel did not collapse, but was only slightly affected.
"It didn't collapse?" The soldier standing on the sidelines was really shocked.
They had just seen and felt the power of the explosion. Under such great power, the mine tunnel did not collapse. This was simply amazing.
How did the princess do it?
All the lieutenants and soldiers looked at Ji Yunkai in unison, especially the general who knew the survey, and looked at Ji Yunkai with even more intense eyes.
He was certain that this was not a coincidence or an accident, nor was it good luck. He knew that this was the result of the princess's precise calculation.
He had heard what the princess said before and knew that the location and quantity of the explosives placed by the princess had been calculated. However, when the princess was calculating, Young Master Feng Qi had been standing nearby, and he was embarrassed to step forward to check.
After all, each sect has its own secret techniques that are not passed down. Some things can only be passed down to direct disciples and cannot be learned by outsiders.
Therefore, even though his heart was burning now, he suppressed it and did not come forward to ask. He just looked at Ji Yunkai and their Princess Yanbei with shock and admiration like others, and thought to himself.
:The prince of their family has really found a treasure. Where can he find a wife like the princess, who can kill people on horseback, is a scholar who can overwhelm the great scholars in the academy, and can also do medicine and mining? (To be continued)
