The sudden change shocked everyone.

"Ahem..." Li Xian crawled up with a pale face.

Just now, Li Xian was really frightened. The sudden explosion occurred very powerful. If it weren't for the eighth level of Qi Refining Stage's cultivation level, he would definitely be seriously injured.

"What's going on?" Everyone was even more panicked. What was panicked was that Li Xian was hurt.

Li Xian was helped by Tang Rong and sat down. Seeing everyone nervous, he suddenly laughed, "Don't worry, everyone... I'm doing research, there will be many such things. Just treat it as cough cough... I'll teach you a lesson.

The reason is also very simple. The small spiritual gathering array can no longer meet the engine's energy demand, so it cracks."

"So that's it, let's portray a larger spiritual gathering array." Everyone proposed this solution without thinking.

Li Xian shook his head, "This can only solve the problem temporarily, but it cannot solve the problem forever. Have you ever thought that the engine now has reached 10 horsepower design power, so what about the future?

In the future, the engine will exceed 100 horsepower, 1,000 horsepower, or even 10,000 horsepower. How should we portray the spirit gathering array at that time?"

"This..." Li Xian's words made everyone distressed. Yes, if the engine reaches one thousand horsepower, would it take a millstone to make a spirit gathering array? That would be too unrealistic.

"Use spirit stones as power!" Tang Rong said, "A low-level spirit stone is ten times that of ordinary spirit gathering arrays. However, a spirit stone can only be used for one hour. Moreover, the Great Xia Kingdom can hardly buy spirit stones."

Is it a spirit stone? Li Xian heard this name again. This spirit stone that was said to be full of the ground in ancient times has now become a rare treasure. Making a defective spirit stone can cause death. Even Li Yulong can't get a spirit stone.

But the word "spirit stone" made Li Xian think of "battery", "energy block" and so on; if a spirit stone can be used as a reference and a "artificial spirit stone" can be studied, then...

It’s exciting to think about it. So, how to get the first spirit stone? By the way, Dragon Palace! If you spend a huge price on yourself, you should be able to exchange for one or even a few spirit stones.

Youdao came whenever you say it. When Li Xian was feeling emotion here, Song Xing came in and notified him, saying: The envoy sent by the Hai tribe has arrived, and he has come to Li Xian’s Qingyun Valley.

The messenger of the sea clan, would he be the legendary Prime Minister Turtle? Li Xian had a head full of evil tastes and inexplicable expectations.

As a result, Li Xian was disappointed. He was not the legendary Prime Minister Turtle, but a real human race. He looked a little vicissitudes and an indescribable pressure - he was a master in the late stage of the Foundation Establishment Period!

"In Xia Weizhe, he came on behalf of the sea clan."

"Hello, Senior Wei, are the design drawings with weapons or samples coming?"

Wei Zhe handed out a jade slip, "Everything is here, including the silk-like spiritual materials, minerals, etc. that the sea clan can now provide, as well as weapon styles."

Li Xian took the jade slip and was about to check it out. Xu Ren suddenly said, "Young Master, let me see what to do first?"

"Sir, please."

Xu Ren checked it before transferring it to Li Xian; Li Xian checked it. Wei Zhe on the opposite side did not seem to show any displeasure.

In fact, Xu Ren's actions are the same as testing poison. Jade slips can be tampered with, especially when facing the legendary existence of the Dragon Clan, it is better to be careful.

When Li Xian looked at the jade slip, he was overjoyed. There was a silk thread called "Fire Spider" here. It turned out that the ocean was vast and there were countless islands of all sizes, and these islands were basically the territory of the sea clan. It should be said that in order to trade with Li Xian, the sea clan also collected a lot of things. However, many good things were particularly expensive, almost twice to ten times that of the sea soul silk. There were even several two-level (Golden Dan stage) spiritual power silk threads here.

However, from the list of these materials, Li Xian keenly discovered some implicit information: the sea clan attaches great importance to stainless steel! I guess the sea clan himself would not have thought that because he was too anxious and attached great importance to it, he tried his best to list all the materials, which actually made the shrewd Li Xian discover this implicit information!

After reading all the materials quietly and after reading all the strange weapons, Li Xian put down the jade slip. "Senior Wei, there is no problem with weapons. Even a trident that is three feet long can be perfectly built."

"That's great." Wei Zhe obviously added a little smile.

But Li Xian suddenly sighed, "But senior, you actually need 1 million kilograms of stainless steel weapons this time, but it is a bit difficult. We can only produce 5,000 kilograms of stainless steel a day now, which is our greatest limit. Forging weapons, especially excellent weapons, almost 5 kilograms of iron can be used to forge a long sword of about two kilograms.

It takes about two years to 1 million kilograms of weapons."

"It takes so long?" Wei Zhe was stunned. He thought it would only take three to five months. But what Li Xian said was correct. Excellent weapons require repeated folding and forging, and finally the so-called "fine iron" was left behind.

Seeing this, Li Xian immediately said: "Senior Wei, we have a way to speed up the production of refining 'stainless vegetarian'. But maybe... we need a little spirit stone. I don't know if the sea clan is willing to sell spirit stones, the price is easy to say. As long as there is a low-level spirit stone, we can extract the stainless steel needed for 10,000 kilograms of weapons."

Li Xian opened his eyes and told lies. Stainless? This is an absolute big fool. But Li Xian didn't know that the three words he said here today would make countless practitioners think about it in the future - Stainless is a god-like thing!

But at the moment, Wei Zhe squinted his eyes and said, "If you were given ten spirit stones, how long would it take to complete the forging?"

"If it goes well within five months, it will be completed in four months."

"Okay! I will add ten spirit stones to you and cancel ten kilograms of sea soul silk."

"Yes!" Li Xian almost gritted his teeth and endured it - sooner or later I will earn tens of thousands of spirit stones from the sea clan.

In this case, in this transaction, Li Xian got ten spirit stones and 190 kilograms of sea soul silk. However, Li Xian was very luxuriously cutting off 100 kilograms of sea soul silk in exchange for some other spiritual silk threads of 30 kilograms.

Wei Zhe left immediately and promised to deliver everything within ten days at the latest. Li Xian also started to get busy. The first is to upgrade the machine tool.

The sea tribes are all huge. The largest of the weapons this time are five tridents that are three feet long, which are the weapons of the sea yaksha.

A trident has a diameter of one foot, and the three forks in front are also as thick as a thigh, weighing about 150,000 kilograms! Just these five tridents weigh more than 700,000 kilograms!

In order to forge such weapons, we must hurry up and upgrade the machine tool, otherwise it will take two years to really forge it manually!

Everyone began to be busy making simple grinding and forging machine tools. The craftsmen were already very skilled and had sufficient technical accumulation; bearings, spindles, workbenches, engines, etc. were prepared one by one.

In order to facilitate the straight movement of the machine tool tool, Li Xian proposed a solution to the screw. The rotation of the screw is used to achieve horizontal movement of the grinding tool, and a smooth guide rod is used to maintain the stability of the tool. In this way, even a three-zone trident can be processed even if it comes with a five-zone trident.

Using machine tools to process new parts and then assemble new machine tools. At this moment, Li Xian's industry began to truly embark on the road of expansion - machine production machines, although it is still very primitive.

The smelting branch and the machinery branch are busy, and the craftsmen, it should be said that the technically capable workers are smiling happily, and the rewards from Li Xian flow into their pockets like flowing water.

With the cheating of spells, in just seven days, Li Xian saw the birth of a large-scale processing machine tool, a machine tool that can process a trident. Although the driving machine tool is several engines with only 5 horsepower, the efficiency of the machine tool is terrible, and the accuracy of the machine tool can make people laugh, the trident that processes cold weapons is enough.

Perhaps the only thing that satisfies this machine tool is several cutting tools that are tempered with true energy in the foundation building stage and attached to the formation. It has to be said that with the cultivation of the truth, it is often as convenient to cheat.

Of course, the so-called terrible efficiency and the accuracy of laughing at the big teeth are in Li Xian's eyes; but the workers don't see it like this.

When everyone saw this huge machine tool with their own eyes, it took only one hour to complete the processing of a test iron column, and the workshop immediately became a sea of ​​joy. Lian Xuren, a strategist, was shocked by this machine tool.

After the celebration in the morning, Xu Ren stopped Li Xian excitedly, "Young Master, Wei Zhe should be coming back soon. I have something to say to you."

"What's the matter?" Li Xian was still immersed in excitement.

"Young Master, Wei Zhe, who serves the demon clan and the sea clan, is not accepted by everyone; therefore, be careful when dating them and don't be too intimate."

"So that's it. Thank you for your reminder."
