Practicing life skills is a boring thing. It takes about three or four excellent mining helmets to upgrade Lu Li to a life skills experience point. It takes more than three hours to upgrade to the six skills that are poor at the advanced level.

Advanced 180, if you upgrade to this level, you can't handle it by the terrestrial mining helmet. You must change to something more advanced.

Lu Li threw more than 20 finished helmets into the warehouse and marked the price of 1 point. Guild members only need one point to take the helmet away, which can be regarded as giving everyone benefits.

Although the terrestrial mining helmet is not precious, it can be sold at least dozens of gold coins.

There are many higher-level engineering formulas in the guild warehouse. Lu Li needs to choose them. The quality of the things they make is not important. The key is to have the corresponding materials on hand.

The result disappointed him.

Engineering is the most difficult life skill, no one. There are many reasons for this result. One of them is that it is very dangerous and will often blow yourself to death. Then there are too many things involved. To make a terrestrial mining helmet, Lu Li needs to smel ore, which is the category of casting and sewing leather. This is actually the content of the tailor. What’s even more disgusting is that he, a thief, has to learn to portray engineering magic circles, which is something that the inscription master is good at...

Finally, the formula and ingredients.

The Sword of Judgment Guild has more than 400 casting formulas and more than 700 tailoring formulas in the warehouse, but there are only 33 in engineering, which is a completely desperate gap.

Moreover, at least 80% of these thirty-three formulas are not suitable for Lu Li’s current engineering level, and the remaining 20% ​​of the formula materials have become a problem again.

The materials required for engineering formulas are relatively complicated, and companion materials often appear. The so-called companion materials are extra harvested during mining or herbs. Mining is generally gems, and medicinal herbs are generally parasitic.

For example, if Lu Li takes a piece of red malachite recipe in his hand, he needs a piece of red malachite. Isn’t this a pitfall? There are things like red malachite. You can sell platinum in the trading store. Who would make a piece of garbage hunting rifle like a fool?

The only drawing that has both materials and is more suitable for Lu Li to use requires engineering 190, which means that Lu Li must be upgraded to another ten points.

The helmet of the terrestrial mining is definitely not able to accomplish this important task.

He thought for a while and gave up the idea of ​​searching for a trading bank. He could imagine how poor the trading bank’s page about engineering recipes was. It would be better to ask Shen Wansan that guy.

"Engineering formula..." Shen Wansan responded in surprise: "You shouldn't plan to upgrade your engineering skills, right?"

"Yes, if there is a recipe to support two, it's easy to discuss if the money is paid." The gold coins in Lu Li's backpack were actually almost overwhelmed by the cost of upgrading the workplace and warehouse. However, he and Shen Wansan are old acquaintances, and he can owe it no matter how much money it is.

"It's not a matter of money. Why do you have to study engineering? This is probably the most promising profession," Shen Wansan persuaded him earnestly.

"Old Shen, do you think the game will design a completely useless life skill?" Lu Li did not explain, but asked back: "Especially when this life skill is still very difficult."

"Uh. But at present, the project obviously has the lowest returns," although Shen Wansan couldn't refute it, but he still insisted on his own point of view.

"In a few months, I guess you won't say that, Lao Shen. If you have engineering formulas, throw them over. It's not easy to take action anyway," Lu Li didn't plan to explain so much that he wouldn't tell others how promising engineering will be in the future.

When everyone realized the importance of engineering, he probably was a master of engineering at that time.

Alchemy is not a must-learn. Because Lu Li has countless alchemists, as well as expert alchemists like sesame stuffed dumplings; there is no need to rush to learn casting, he has casting hammers, and the success rate is higher.

Only engineering is the most important thing. The reason is that there will be many engineering things that cannot be traded in the future.

Only what you make can be used by yourself.

"I have seven engineering recipes here. You can see if there is anything that can be used. Even if the money is left, no one wants it if it is thrown out anyway." Chen Wansan and Lu Li have a good relationship, but they are not so arrogant that they want to plan their life for Lu Li. He advised him a few words. Seeing that Lu Li was unmoved, he gave up.

Lu Li looked at the recipe he sent and chose two.

The gnome stealth device, the carrier can use this thing to obtain a short stealth ability, lasting thirty seconds, with a cooldown of 60 minutes, and can only be used in non-combat states.

It's useful, thirty seconds are too short and cannot be used during battles.

It's useless. In fact, many people are used to bringing one with them. Maybe they can save themselves from their own experience at any time. The most important thing is that this formula requires an engineering level of 180, which is exactly the most suitable drawing for Lu Li at present.

The only bad thing is that the main material of this thing is Mithril.

Among the ores that players can pick at present, Mitsunian is almost the most precious. It is conceivable that it will cost a lot of gold coins to upgrade with this recipe drawing.

Another recipe is self-destructing sheep.

Self-destructing sheep is more practical than gnome stealth device, and the effect of the bomb is basically the same as that of Ivy's bomb. Players can command this mechanical sheep to rush into the group of monsters to explode, but it uses more materials than Ivy's bomb. However, some local tyrants still use it to upgrade in luxury.

Self-destructing sheep requires engineering level 190, just after the dwarf stealth device.

The other formulas were either lower than 180 or the ingredients were hard to find. Lu Li gave up these and chose only these two. He asked Chen Wansan to mail them over and quickly got them in his hand.

The materials used to make the gnome stealth device are mainly mitesilver, followed by jadeite, secondary moonstone, citrine, and fuses.

The production process is divided into two parts. First, use Mithril and secondary moonstone to make a "spring-style synchronous coordination gyroscope", and then add materials to make a finished dwarf stealth device based on the winding-style synchronous coordination gyroscope.

Lu Li now divided the mitral silver ingot with a size of more than eighty into five parts, and then took the large piece of metal to melt it.

The smelting here is not about melting it into liquid, but softening the surface to facilitate the portraying of the engineering array on it. This is the main body of the gnome invisible device, and it is also the key to success or failure, and it takes the most time.

Lu Li carved the engineering magic array and then carved the four small ones according to different requirements.

After the parts are made, the next step is to assemble them.

Five parts need to be integrated with certain runes. Each rune carved on it must be connected with other parts. As long as there is any docking error, it may cause the failure of the gnome stealth device. (~^~)
