Anyway, it is impossible to use spirit stone energy 100%.

However, this method is better because it is maneuvering and flexible. With a thought, the mountain magic shield can reach the sky and the earth, hundreds of meters or even thousands of meters in an instant.

The latter is controlled by force and cannot escape from the body. It is not that flexible, but it is stronger than solid enough and has an energy shield. As long as it forms a dense front, the defense effect is still very considerable.

Finally, the production of the mountain magic shield is a combination of people and different quality, but the mechanical tower shield can be produced on a large scale.

Even if a mountain magic shield is comparable to ten mechanical tower shields in terms of performance? It can be suppressed in quantity.

From this point of view, Tang Yizhou realized that the biggest variable in the duel between the Immortal Cultivation Legion and the Mechanical Legion is to see who has more resources and who can convert resources into war resources faster and better.

Of course, this premise is that both sides do not use higher-level forces.

After more than an hour of research, Tang Yizhou had already understood the concept of creating the mountain Dharma shield, but he planned to use the eighteenth level calculation to optimize it.

It can not only strengthen the quality of the finished product of Shanyue Law Shield, but also speed up the production process. Why not do it?

Fifteen minutes later, Tang Yizhou successfully obtained the optimized version of the Mountain Magic Shield at the cost of 18 years of life. The overall quality was increased by more than 50%. The most important thing is that this Mountain Magic Shield consumes energy, that is, mana consumption, and mana, is reduced by 40% compared to the original version.

After hesitating for a while, Tang Yizhou castrated this optimized version and kept its improvement range below 10%.

This is the case for the time being. When will his body break through the second life leap, that is, after entering the foundation-building period, it will be no longer too late to let go.

Next, Tang Yizhou used those ten resources to upgrade a complete set of preparation tools for himself, and then made some materials into parts of the Shenjiang A-3 type engineer. Finally, it was formed in one go, creating a mountain magic shield.

And at this time, a day has passed.

Taking this mountain magic shield, Tang Yizhou went straight to the garrison to find the middle-aged manager to deliver it. He was still quite nervous at this time, afraid that he would take extraordinary actions and be as arrogant as a king.

But after checking the mountain magic shield, the middle-aged manager was very happy and extremely happy, but he absolutely did not have a shock or admiration.

"Brother Zhou is a talented person. It is not an exaggeration to say that you are a disciple of the outer weapon refining in Panshan Sect with your refining technique!"

"Exterior door?"

Tang Yizhou was a little confused. Are the people in this world so awesome?

"Hehe, Brother Zhou, don't be surprised. In fact, you are already very good. With time, with Brother Zhou's talent in refining weapons, you may be able to join Panshan Sect and become an inner disciple."

"Maybe? Inner disciples?"
