Longevity, starting from the blood contract turtle

After Chen Ziming and Paopao got the blueprint of the special self-destructing rune array from Mr. Lu, they could solve all the problems by themselves except that their rune engraving level was not up to the requirements and they did not have the energy of a strong man.

Mr. Lu took out all the mithril ore he had collected. Chen Ziming saw that there was quite a lot of it. He did not know where Mr. Lu got it from.

Chen Ziming and Paopao kept refining mithril in Paopao's tortoise shell space laboratory.

Every time they refined a part, they would withhold some and keep it, so as to control the output of mithril from the mithril ore at the average level of an alien world.

The method of refining mithril that Chen Ziming and Paopao developed using science and technology and rune technology was much more advanced than the general mithril refining method in the alien world, and there was basically no loss of mithril.

They withheld some mithril, not only to prevent Mr. Lu from seeing the abnormality, but also to keep some of the magical mithril for further research and application.

When they were refining mithril, Mr. Lu was already using mithril to re-refine the tribe's protective array.

The 108 rune arrays that were originally used for the formation were taken out one by one by Mr. Lu, and mithril was added to them on the spot.

The amazing thing is that when Mr. Lu added a small amount of mithril to the array made of spirit iron, and the spirit iron evolved into a more advanced mithril spirit iron, the runes and hidden runes in the rune array did not change or be damaged.

No wonder Mr. Lu was the first to upgrade the tribal protection formation with full confidence. It turned out that such an upgrade was so simple and easy to operate.

Without closing the tribal protection formation, Mr. Lu quickly upgraded the 108 rune arrays that were used for the formation to mithril spirit iron rune arrays.

That was not all. Mr. Lu made some adjustments to the entire formation, and added hidden runes and spirit stones, which greatly improved the power of the entire set of protection formations.

After upgrading the tribal protection formation, Mr. Lu specially called Chen Ziming to introduce him to a more powerful version of the protection formation and explained his ideas for upgrading the formation.

"After this upgrade, even if the giant crocodile demon comes in person, he can only sigh and do nothing!"

"Haha, now I am completely relieved!"

"My friend, this is all thanks to you!"

"..."

Chen Ziming looked at Mr. Lu's heartfelt smile and knew that Mr. Lu had really resolved a big knot in his heart this time.

During the years that Mr. Lu has been guarding the human tribe of Octopus Island, many irreparable tragedies have occurred because of him.

The human tribe of Octopus Island has always had such a small population and such a high proportion of orphans. It is conceivable how many crises and sufferings this tribe has experienced.

As the guardian of the human tribe, Mr. Lu has been experiencing these things. The sadness, depression and powerlessness in his heart are unimaginable to ordinary people.

Since Lan Zhuer brought Chen Ziming back, all this has begun to change.

It was with Chen Ziming's selfless help that Mr. Lu was able to truly put his various plans that only existed in his imagination into reality.

With the powerful rune protection formation, this small human tribe on Octopus Island has a solid foundation to stand on.

All of this was seen very clearly by Old Lu and the people of the human tribe on Octopus Island.

The gratitude of Old Lu and the entire human tribe on Octopus Island to Chen Ziming could no longer be expressed in words.

Therefore, Old Lu has been passing on his various knowledge and heritage to Chen Ziming without reservation.

He also hopes that Chen Ziming can bring greater hope and development to this small human tribe on Octopus Island in the future.

After the upgrade of the protective formation of the human tribe on Octopus Island was completed, Old Lu took Chen Ziming with him, asked Chen Ziming to take out the rune armor and the rune axe, and taught him the skills of using mithril to forge and upgrade weapons and equipment bit by bit.

How to upgrade the spirit iron to the mithril spirit iron without affecting the light and dark runes;

How to engrave more runes in the mithril spirit iron to store more energy;

How to design and refine the rune array that is easy to carry and quickly deploy;

How to use the rune array that you carry with you to fight;

How to refine the special rune self-destruct array as a self-defense trump card;

How to strengthen the spiritual power and improve the rune engraving level when the strength level is not enough;

…

This time, Mr. Lu not only taught and demonstrated in person, but also let Chen Ziming keep practicing and practicing various abilities.

Especially the ability of rune engraving, Mr. Lu taught the skills of improving spiritual power through the human visualization method, and let Chen Ziming improve the rune engraving level by constantly engraving simple runes.

"You know, the surface area of ​​an object is limited. No matter how high the level of rune carving is, there is also an upper limit."

"But dark rune carving is different. Although the volume of an object is also limited, a high level of dark rune carving can engrave extremely tiny energy runes into the microscopic space of the object, and can also play the effect of runes."

"In theory, this superb dark rune carving technology can engrave countless runes on extremely small objects to achieve unimaginable effects."

"So, whether it is a rune master, a forger, or a rune formation master, the rune dark carving technology is extremely important!"

"..."

Old Lu was worried that Chen Ziming, who had superb open carving technology, would go astray, and especially emphasized the importance of rune dark carving technology to Chen Ziming.

He also personally supervised Chen Ziming's training of rune engraving techniques.

Chen Ziming understood Lu Lao's good intentions and practiced rune engraving techniques very seriously.

Chen Ziming used his spiritual power to control energy, forming runes one by one, and inserted them into the spirit iron. He kept practicing until his spiritual power was exhausted.

After repeated training, Chen Ziming's rune engraving level was greatly improved.

In the future, he will personally forge fine rune weapons and rune arrays, and he can design some engraved runes.

With the joint efforts of Lu Lao, Chen Ziming and others, a certain amount of mithril was consumed, and they upgraded the rune weapons and equipment in the entire tribe to mithril spirit iron.

The forging material of rune weapons and equipment was upgraded from spirit iron to mithril spirit iron, and its various performances were doubled or several times improved.

This instantly greatly improved the combat power of the entire human tribe.

The weak first-level human race could only be killed instantly by the third-level enemy. Now with the Mithril Spirit Iron Rune weapons and equipment, they can fight against the third-level enemy.

At least they can ensure that they will not lose their lives.

The human races of other levels also have the ability to protect themselves and even kill enemies in cross-level battles.
