Longevity, starting from the blood contract turtle

After Chen Ziming and Bubble posted the evidence online, they stopped paying attention.

They knew that with these things, Mingchuan Capital could no longer survive in Xia Country.

As for how Xia Country would deal with them, Chen Ziming could not guess.

One person and one turtle returned to Octopus Island in another world.

They had also learned all the knowledge of the advanced version of the rune array given by Mr. Lu, and were constantly comprehending and practicing.

Mr. Lu gave Chen Ziming another task. Refining the rune array required a large amount of spiritual iron. He asked Chen Ziming to refine as much spiritual iron as possible during this period for future use.

The current spiritual iron refining work has been handed over to the intelligent manufacturing center in Bubble's tortoise shell space.

Bubble can directly provide energy to drive the rune equipment in the tortoise shell space, and Chen Ziming does not need to worry about it.

If there are enough spiritual stones in the future, they can also be replaced with spiritual stones to drive.

Because of Bubble's talent and the huge amount of evolutionary energy consumed, the upper limit of energy storage in its body is much higher than that of the fourth-level Ruyi Turtle.

Moreover, Bubble's energy recovery speed is much stronger than other level 4 Ruyi turtles.

Therefore, with Bubble's energy support, it is not difficult to refine a large amount of spiritual iron in a short time.

Spiritual iron is a metal with great use. Chen Ziming seizes the opportunity now and refines some every day for storage.

The crude iron that Lu Lao had refined in his previous experiment has been used up by him. Now to refine spiritual iron, Bubble has to go to the location of the spiritual iron mine and dig it himself.

Bubble can control various intelligent tools in the tortoise shell space to help, but this is the territory of the human tribe. It dare not use things with obvious blue star characteristics.

After a while, Chen Ziming told Lu Lao that he had prepared enough spiritual iron.

Lu Lao asked Chen Ziming to wait for two more days and asked him to study the refining method of the rune array in these two days.

Two days later, Lu Lao finally completed his array design.

"The original array was made by me alone, and I personally engraved the runes both openly and secretly."

"In the past, we had to consider the consumption of spiritual iron and the time-consuming refining, so we designed it the way you saw it last time."

"Now that you have the means to quickly engrave runes and have a sufficient supply of spiritual iron, I have changed the design of the rune array."

"The size of the array has been increased so that more runes can be engraved openly, which greatly reduces the use of hidden runes."

"In this way, we can quickly refine a large number of rune arrays!"

"With enough rune arrays, we can set up an unbreakable and powerful defensive rune array!"

Old Lu said to Chen Ziming excitedly.

According to what Chen Ziming learned from the books, the refining of each array requires a lot of time, energy and materials for the rune array master.

In order to find a suitable balance between time, energy consumption and material consumption, the rune array master needs to design and modify the refined array to meet actual conditions, just like what Old Lu has been doing recently.

"I will now explain to you in detail the rune array we are going to refine. Please listen carefully. If you don't understand anything, you can interrupt me at any time to ask questions!"

"When you understand this rune array, your rune array will be considered to have made some progress, and then we will start refining!"

Old Lu took out a pile of rune drawings and began to explain to Chen Ziming the rune array he designed and modified himself.

Chen Ziming and Bubble listened to the lecture beside Old Lu.

This listening lasted for two days.

A truly practical rune array with powerful functions contains a lot of rune array knowledge, and many of the inconspicuous details have profound meanings.

There are also many experiences and skills that are not recorded in books.

It can be said that in these two days, Old Lu was passing on the rune array inheritance that truly belonged to him to Chen Ziming bit by bit.

Chen Ziming did not disappoint Old Lu. With the sixth-level [Wisdom] talent, he is an extremely ideal good student.

No matter how obscure and difficult it was for Master Lu to explain, Chen Ziming basically understood it after listening to it once, and he rarely asked questions on his own initiative.

Most of the time, Master Lu was afraid that he would speak too fast or not express himself clearly, so he stopped on his own initiative and asked Chen Ziming if he understood.

Master Lu found that as long as he explained the knowledge points clearly, Chen Ziming could quickly understand and integrate them regardless of the speed or difficulty, so he spoke faster and faster, and spoke heartily.

Chen Ziming was also fascinated by learning, and Bubble, who was listening next to him, was even more relaxed.

The content that Master Lu originally planned to spend some time to explain slowly was all finished in two days.

"My friend, your learning ability and understanding are really strong!"

"In the way of rune formations that I am best at, you will soon surpass me!"

"Haha, there is really a successor! There is a successor!"

"Work hard!"

"..."

After Master Lu imparted all the knowledge to Chen Ziming, he couldn't help but say to Chen Ziming with relief.

"Thank you, Mr. Lu, for the inheritance!"

Chen Ziming also sincerely thanked Mr. Lu.

Whether it is the current Blue Star, or the Blue Star of any era, or in fictional novels, movies and TV shows, humans rarely have such selfless inheritance.

So, Chen Ziming felt very lucky. The second time he met a human tribe, another selfless elder was in charge.

"Haha, don't thank me!"

"Take a break, and then we'll get to work!"

"My friend, your grilled meat is still delicious. Let's grill some meat first!"

As Mr. Lu said this, he took out two large pieces of snow-white tender meat and asked Chen Ziming to help grill it.

Chen Ziming also took out the grilling tools and seasonings without saying a word and started grilling meat.

After the two of them had enough food and drink, they rested and adjusted themselves, and then began to refine the rune array.

Chen Ziming took out the spiritual iron, and Mr. Lu made a fire in the void to refine it, occasionally engraving some runes, adding some materials, and concentrating on refining.

Soon, a rune array with a diameter of about one meter gradually took shape, which looked much larger than the rune array Chen Ziming had seen before.

The rune array took shape, and Mr. Lu kept using rune handprints to assist and secretly engrave runes. Chen Ziming also witnessed Mr. Lu's powerful strength and rune technology level.

The energy-constructed hidden runes flowed into the rune array like a small river of energy runes, and were accurately engraved in the right place.

There were many, fast, and orderly, which looked pleasing to the eye.

About ten minutes passed, and Chen Ziming saw that Mr. Lu was struggling a little. The hidden runes on the entire rune array were finally engraved.

"Successful at one time! After the design improvement, it is much easier to refine!"

Mr. Lu finished refining and said with some pride.

"The next rune engraving will be left to you, my friend!"

Mr. Lu handed the rune array he had just refined to Chen Ziming.
