After sending off the policeman's sister, Lin Ye was able to carefully appreciate the enhancement of spiritual strength and what changes it would bring to him.

Theoretically speaking, after absorbing the soul energy of two people, the spiritual power should be at least doubled, assuming that Lin Ye's original spiritual base was 1, it should be increased to 2 now.

For Lin Ye, the best way to verify is to memorize words, solve puzzles and play games, memorizing words is for memory, solving math problems is for comprehension and calculation ability, and playing games can verify conscious thinking, reaction speed, subtle manipulation and many other items.

It took two hours for Lin Ye to solve a few math problems, memorize a hundred almost unfamiliar English words, and then play three rounds of masturbation, and then let Aike dictate the words for himself.

It was concluded that the game was much more slippery than before, the word was good, and there was already a beginner level that was unforgettable.

You know, when Lin Ye was in school, the biggest headache was memorizing words, and today I had a very relaxed and very enjoyable strange feeling, which was completely different.

As for solving mathematical problems, this aspect is Lin Ye's strength, and the improvement is not obvious, but he feels that his thinking is clear and his state is excellent.

In addition to these, even the sense of sight, hearing, and smell has become much sharper, and Lin Ye knows that this is the overall perception has become clearer, which belongs to the update of the software level, not the upgrade of the hardware level.

In addition to the excitement, Lin Ye asked Ike: "If the current spiritual base is 2, how many do I need to improve to master the bullet time you said?"

"Four or five...... Meaning, you still have to devour eight to ten soul energy. ”

Aike replied: "However, if you are willing to spend demon coins to buy spirit grass, I will refine a few soul nourishing potions for you, and it should be achieved within half a month." ”

The soul-nourishing elixir is a low-level elixir, and any demon in the spark period knows how to refine it (except for some beast demons with low IQ)

"Don't worry, we'll see in a few days. ”

Of course, Lin Ye knows how to calculate this account, if someone comes to die one after another in the near future, devouring soul energy is of course the most cost-effective, and there is no need to spend money at all.

In the afternoon of the same day, Lin Ye and Aike went to Canglong Mountain and received one hundred and eighty kilograms of gold and more than forty sapphires from Dudu.

This is the result of more than ten days of labor by Dudu, but Dudu said that the mineral deposits below are not as rich as imagined, and after another ten days of digging, they will almost be hollowed out.

Lin Ye felt very satisfied, this vein as a whole would contribute one hundred and seventy or eighty demon gold coins to himself, as well as tens of millions of yuan, which was already very good.

The point is, mining to make money is neither effortless nor risk-free, just throw the dodu here and don't have to worry about it yourself at all.

What could be more comfortable than this way to make money?

Returning to the blue ocean after dark, Lin Ye sent all the gems to Hong Hai, there is no need to talk about how much money can be sold, let Brother Hai operate slowly, after all, the processing and sales of gems are more complicated things.

Lin Ye believes that Brother Hai will not play tricks on this kind of thing, and a batch of goods will be eight million if they die, with his financial resources and the relationship between the two, it is really not worth messing with behind his back.

One hundred and eighty kilograms of gold, Lin Ye left forty kilograms as a backup (including the commission reward to Dudu), and the other one hundred and forty kilograms of pawns were given to the system, which was converted into 70 gold coins, and this time, the balance of gold coins in the account was directly over 100: 111!

Rich!

This makes it possible to hire the subordinate labor of the higher demons to carry out the supporting works of the underground buildings.

As of today, the underground base has five floors, with a usable area of 100,000 square meters.

At this stage, there is an advantage to hiring auxiliary labor, Bobora is still there, she can directly direct those human laborers to carry out the construction, the two aspects of on-site cooperation, if there is a problem, Bobora can also change it at any time.

If Poppola returns to the Demon Domain in another ten days, the main structure cannot be changed or adjusted.

Through the mercenary system, Lin Ye contacted a tyrannical Yan Huang who was a high-ranking one-star, this guy's name was not distinctive, but the nickname was quite interesting, called the Purgatory Forge Bag Foreman.

After communicating with Lin Ye for a few words, Brother Yanhuang said: "Brother, don't worry, my slaves are all qualified craftsmen, and there is absolutely no bastard, and they are the best at underground construction, magic department, formation department, and technology department." The amount of work you have over there, it's enough to send a hundred people, ten magic departments, ten formation departments, and the other eighty are science and technology departments, what do you think?"

It sounded good, but Lin Ye was more concerned about the price, so he asked, "How much does it cost?"

"The charging standards are all set to death, how dare I ask for a price. ”

Yan Huang replied with a big grin: "The slave craftsmen of the human race, the team of 100 people is one gold coin a day, you can take care of food and housing." If you don't obey the discipline, you can kill at will, but if the number of deaths exceeds half, you will have to pay me a gold coin for each death. ”

Lin Ye was stunned for a moment, and his inner reaction was: Damn, it's really so cheap!

Or, in the eyes of demons, human slaves are as cheap as mustard and worthless, and a team of 100 people, if there is a death during construction, as long as no more than half of them, they do not need to be compensated for a penny.

This is still a craftsman-level skilled job, if you change to a slave army, a thousand elite soldiers (the system does not allow weapons and equipment), and the hiring fee is only one gold coin per day.

It's normal to say, after all, the short-term employment fee of the Gathering Demon's is only one gold coin a day, and long-term employment is cheaper. And many types of tasks, the Gathering Spirit Demon can completely, but a thousand human soldiers may not be able to do it.

So, human slaves are so worthless.

As a member of the human race, Lin Ye would feel that this was quite excessive, but in fact, a demon slave owner would have thousands, tens of thousands, or even hundreds of thousands of human slaves, and they had to raise them for nothing on weekdays, so it was better to be cheaper and scatter them out to earn gold coins for themselves.

If you can earn one, count as one, otherwise, what's the use of keeping them.

"Alright!"

Lin Ye felt that there was no need to negotiate with other demons, and immediately decided: "Send me such an engineering team, but they must all be capable and good hands." ”

"No problem!"

Yan Huang roared and laughed wildly: "Those who can't work have already eaten them, why should I raise them for nothing." ”

Lin Ye twitched the corners of his eyes when he heard this, and said in his heart that this Nima is too vicious, worthy of your purgatory furnace and tyrannical name.

Next, Lin Ye first went to the basement level, called Bobola to the front, asked her for her opinion, and then signed an employment agreement with the tyrannical Yanhuang for the attached laborers.

Hula!

The space was distorted, and after the teleportation was completed, a large group of human slaves appeared in front of them, in a row of ten, in a neat line.

Obviously, this was not the first time that they had accepted similar hires, and after coming over, they saw the environment clearly, so they knelt down at Lin Ye and said in unison, "Meet the mercenary." ”

In this situation, Lin Ye was a little confused, and for the first time he enjoyed the rotten treatment of hundreds of people kneeling down to worship him, in addition to being surprised, he was more complacent.

It is no wonder that the emperors and officials in ancient times, who were so subdued by the people, did have a sense of accomplishment and satisfaction of the people.

One hundred human craftsmen, all empty-handed, are not allowed to carry their tools, only ordinary clothes without any enchantment.

In the front row, dressed in black robes, Poppola said they were magician-based builders.

The second row wears gray robes, which belong to the formation construction craftsmen.

In the back eight rows, the clothing features are more messy, and there is no doubt that they all belong to tech-based architects or engineers.

It can be seen that the Demon Domain is still respected by spells, and the scientific and technological power is the bottom.
