Chapter 54: Dynamite

　　 Richard was walking on the mountain road, frowning slightly, and had already walked around the mountain almost, but did not find any passages and cracks. Combined with the exploration of the conscious body before, it can basically be determined that taking a shortcut to take the crystal skull out of the mountain is basically impossible.
　　 Then I can only find a way to cut out a channel from the outside of the mountain, enter the chamber inside the mountain, and then take out the crystal skull.
　　 If this is the case, it will be a large-scale project, especially in the current medieval world.
　　If you simply use hammers and anchors with human power, it is difficult to complete in half a year.
In terms of spells, there are indeed earth-based spells in the Chapter of the Monroe that destroy rocks. I have recently learned one, but at the wizard apprentice level, it can only be performed on a very small scale. Even if it is used continuously, the effect is very general. .
　　 Still have to find a better way.
　　 Li Cha narrowed his eyes, stopped on the mountain road, and looked at a rock wall beside the mountain road, thoughtfully.
　　 Richard knows that the tens of meters behind this rock wall is the secret room, but how can he dig this distance at the fastest speed?
　　Thinking for a moment, Richard raised his finger to the rock wall and read a spell in his mouth.
　　 "Wow...Wow..."
　　 On the rock wall, the rock cracked and peeled off a little bit.
　　Planetary Earth Spells, Zero Ring Low Order, Earth and Stone Control.
　　 "Wow, wow", the rock keeps falling, splashing a lot of dust, it looks very powerful, but in fact for a long time, only a hole with a diameter of three or four centimeters and a depth of more than ten centimeters comes out.
　　Richard looked at the hole, pursed her lips, and pronounced the spell again. After a while, a mass of liquid oxygen was born, filling the hole.
　　After doing this, Richard thought about it, and found some wood chips and hay from the neighborhood, and stuffed it into the hole. When it was full, the standard liquid oxygen explosive was completed.
　　 Yes, liquid oxygen explosives-in the true sense of explosives, there are some differences in the usual liquid oxygen group explosion, because it is filled with some combustibles.
　　Liquid Oxygen Explosives is a type of mine explosives, invented by German Linde on modern earth in 1895. Generally, combustible materials (such as carbon black, coal ash, paper scraps, wood chips, etc.) are wrapped into cylinders, immersed in liquid oxygen before use, and after being filled with liquid oxygen, they are immediately transferred to the place where they need to be exploded.
　　 After detonation, the combustibles inside burned quickly, the temperature rose sharply, the volume swelled up, and the explosion was triggered. The power is greater than TNT and other nitro explosives.
　　 Liquid oxygen explosives are extremely low in cost under a complete industrial system, but because liquid oxygen volatilizes quickly at room temperature, the explosive life is very short, generally 15 to 20 minutes, and must be temporarily impregnated before use. Therefore, it cannot be used for bullets, bombs, shells, etc. It is a "peaceful" explosive, and the biggest use is industrial mining.
　　Simply put, this is the explosive specially used to open the mountain.
　　 Kaishan explosives, explosives Kaishan.
　　 Retreated, turned his head, looked at Pandora, and pointed to the side.
　　 Pandora's eyes flickered, understood the meaning, and walked to the side slightly reluctantly to dodge.
　　 Richard took a deep breath, fixed his gaze, waved a flame, and shot at the liquid oxygen explosive in the hole.
　　 followed closely, releasing an air wall in front of him.
With the sound of "boom", the flame flew into the hole, detonating the real liquid oxygen explosive, the rock wall shocked suddenly, and a huge concave hole was exploded along the slotted hole, and the gravel collapsed like a bullet Going out, flying in all directions, and then being slammed down by the air wall.
　　When the dust settled, Richard removed the air wall, glanced at the effect, and found that he was satisfied. At least using liquid oxygen explosives to open mountains is more efficient than using manual and simple spells, and the entire project can be completed in less than a month.
　　 But in this process, some problems that may occur should be fully considered.
　　After all, to dig a tunnel, it is not necessary to just use explosives to keep bombing.
　　The violence and destruction of a brain can't solve any problems, but the real solution is to rely on the brain.
　　It seems simple to dig a channel, but in fact there are many aspects to be considered, otherwise it will not develop into a complete industry on modern earth.
　　The method of digging tunnels with holes filled with explosives is called drilling and blasting on modern earth, which is mainly used for the construction of mountain tunnels. In addition to the most core blasting, a series of problems such as measurement pay-off, support reinforcement, ventilation, smoke exhaust, and discharge after blasting should also be considered.
　　Although the tunnel is now ready for one-time use, it is not intended to be used repeatedly, and there are no strict requirements for some safety aspects, but it cannot be ignored. Otherwise, what if the tunnel is cut halfway through and blasted once, and the entire mountain is directly destroyed? According to the volume of the mountain, it really collapsed and buried in it, not to mention that the wizard apprentice, the real wizard, could not live.
　　 Therefore, some problems must be clearly thought out, and a solution can be found before real excavation can begin.
　　 For example, the problem of brackets will need to be solved~EbookFREE.me~ It is feasible to reinforce with wood, and there is no shortage of wood in the forest. But it is better to get some high-quality iron.
　　 is just the mining, refining, and building of iron, which is more troublesome than drilling the tunnel. If you make it by yourself, it will take too long. Fortunately, the technology content is relatively low. The current world already has a relatively mature system. You can directly contact the outside world and solve it by purchasing.
　　 Money, you own it. There are many gems in the suitcase. After all, in order to get rid of the shackles of identity and leave the Blue Lion Kingdom, it was planned long ago, and all aspects were considered. But it is not enough to have money, and there must be traders who can be traded.
　　 So... Where can I find it?
　　 Or, think of other solutions?
　　 Richard pondered, and waved to Pandora and walked down the mountain.
　　……
　　 Push the time forward a little bit.
　　 In the forest beneath the mountains, the dead leaves are densely covered, and the sound of horseshoes sounds.
"Da da da……"
　　 Prince Glory was riding on the horse, and the rest of the nobles were vaguely guarding. Furthermore, the soldiers on the outside are alerting while investigating. Their task is to first find the beast to notify the nobility, let the nobility hunt, and prevent the beast from going crazy and causing the nobility to be injured.
　　 At this moment, a strange roar suddenly sounded on the nearby mountain.
　　 "His!" Some horses were startled, their forelegs were raised high, and then they fell heavily, stepping out two deep depressions on the ground.
　　 "What's the situation?" Someone shouted.
　　 Everyone immediately guarded, pulled out their weapons one after another, and looked around with caution.
　　 One second, two seconds, three seconds...
　　Half a minute passed, but nothing happened.
This……
