"Teacher Shi, how far is this observation distance?" Feng Jingyu asked.

Ishihara said, "It's about three kilometers away."

"Three kilometers? It's a bit short." Feng Jingyu muttered to himself: "If it is on the earth, the distance of three kilometers is definitely very good, but here, the distance of three kilometers is definitely not enough."

"Three kilometers is not enough?" Ishihara frowned.

Feng Jingyu said: "At least five kilometers or more. If you are a strong person, you can reach a distance of five kilometers in the blink of an eye. If I am exposed, there is no time to escape."

Ishihara thought for a while, felt that it made sense, and said, "Then let me see if I can adjust the distance a bit further."

"Other aspects are pretty good, especially the clarity I am quite satisfied." Feng Jingyu said.

Ishihara took the telescope and started research again. Feng Jingyu also participated in it. After the two did several experiments, it took seven days to increase the telescope's distance to six kilometers, but the clarity after six kilometers. It's a little bit worse.

After the sniper rifle was completely installed, Feng Jingyu and Ishihara went up the mountain to test the power of the AK47 and the sniper rifle.

The test of the AK47 is relatively simple. It depends on the speed and power of the bullets. Feng Jingyu raised his gun against a rock wall and began to fire frantically. The bullet left a large hole in the rock wall.

In order to personally test the power of the AK47, Ishihara also asked Feng Jingyu to shoot at him, and he defended with aura.

The bullet hit the aura defensive wall, and could no longer get half a point ahead.

Ishihara waved his hand, all the bullets were rolled up, and then fell to the ground, saying: "The power is good. Although it does not pose any threat to me, it is definitely threatening in the realm of the spiritualist."

Feng Jingyu said: "As long as my strength increases, the power of this gun will naturally increase."

"Try this sniper rifle again." Ishihara said.

Feng Jingyu nodded, then came to the top of the mountain, took up the sniper rifle, aimed at a big tree about five kilometers away, and fired.

In just a second, the big tree fell down.

Feng Jingyu took a look at today's weather. The wind was about three to four levels. After the bullet was shot out, there was basically no arc, and the stability was relatively high.

The current sniper rifle is different from the sniper rifle on the earth. The sniper rifle on the earth is not controllable, but the sniper rifle that has become a spiritual weapon can be controlled. As long as the aura is strong enough, it can be maintained even in the face of twelve-level wind straight line.

"Teacher Shi, I will try with a sniper rifle to see how much threat it can pose to you." Feng Jingyu said.

Ishihara went about five kilometers away, and then burst out aura to form a defensive wall. Feng Jingyu aimed at Ishihara's body and fired a shot decisively. The bullet quickly hit the defensive wall.

Ishihara's body trembled and the bullet bounced out.

Feng Jingyu observed the situation on the opposite side from the telescope and muttered to himself: "The power is expected. There should be no problem with the fifth and sixth floors of the spiritualist, and they are all sudden moves. Without precautions, the effect is absolutely absolute. It's not bad."

Ishihara walked back and said, "The power is good. If my aura is not strong enough, this bullet can completely penetrate my defense."

Feng Jingyu said: "Not bad, all within the expected results."

When the two returned to Jiuyuan City, Ishihara asked curiously, "What is the big work you said? Can I say it now?"

Feng Jingyu brought Shi Yuan to his table, and with a wave of his hand, all the drawings he had drawn appeared on the table.

Ishihara picked up the drawing and looked at it. The more he looked at it, the more he was surprised. He felt that his brain capacity was not enough. What did Feng Jingyu's head think? He could even imagine such a thing.

Feng Jingyu smiled and said, "This thing is what I will work hard to accomplish next. If it can be completed, it will be unprecedented."

"What the **** is this?" Ishihara asked curiously.

Feng Jingyu said, "I'll name this Warrior Warrior."

"Steel armored warrior?" Ishihara said: "The name is really loud, but the process is too complicated."

"Don't talk about the process, even the best materials have to be selected, and now I can't find all the materials in the Craftsman Association." Feng Jingyu said.

"Maybe some materials can be found in the Shenqi Empire." Ishihara said: "You have learned all of my things now. I can't teach you anymore. You can go to the Shenqi Empire."

"Teacher Shi's refining technique is still beyond the reach of the kid, and the boy is not going anywhere now, and he is practicing refining technique here." Feng Jingyu said solemnly.

"Your kid is really a fool, what's the future of following me? You practice with others, and you will definitely make progress much faster than following me, and you have learned a lot. Maybe some of them are something I have never learned before." Ishihara said.

"I can learn half of what you have learned, Teacher Shi, which will be enough for me to benefit for a lifetime." Feng Jingyu said.

"Your kid is a piece of material. If you get delayed here, the old man will become a sinner in the world of refining craftsmen. You should pack up and get rid of it." Ishihara said angrily.

Feng Jingyu said: "To tell you the truth, I cannot be known by too many people. I hope you will always work with me to complete a great plan of mine."

"Great plan?" Ishihara wondered.

"I am going to make these things of mine into a modern weapon book. This book will record all kinds of new spirit weapons and production methods, etc., and leave some useful things for later generations." Feng Jingyu said.

When Ishihara heard this, he looked at Feng Jingyu in surprise. He didn't expect Feng Jingyu to have such a bold idea.

"This is not an easy task." Ishihara said.

"I naturally know this is not easy, so I hope you will always finish it with me." Feng Jingyu solemnly invited.

Ishihara was silent for a moment, and hesitated: "Boy, I don't understand many things. I'm afraid that you won't be able to complete what you need then, and that will delay your plan."

"It doesn't matter if you don't understand, let's learn together if we don't understand. I think if we really complete this modern weapon book, it will be a great blessing in the world of refiners." Feng Jingyu was very longing.

"Okay, I promise you all." Ishihara's eyes shined brightly, and he nodded immediately and agreed.

Feng Jingyu was extremely delighted, and said: "Then we will start from Zhuge Liannu, and I will draw some other spiritual tool samples one after another, and we will refine them together."

"It's really unexpected. At this age, the old man can still be so crazy once. If he can really complete the modern weapon encyclopedia you said, then the old man will have no regrets in refining weapons in this life." Shi Yuan felt a bit of tears. .

"Teacher Shi, your attitude towards refining tools will inevitably be very rewarding." Feng Jingyu said.

"Haha, I just have a clear conscience." Ishihara laughed.

Afterwards, the two continued to study the steel armor warriors mentioned by Feng Jingyu.

It took another ten days for Feng Jingyu to draw all the parts of the armored warrior, especially meticulous, without letting go of any details, allowing Ishihara to see clearly.

"Teacher Shi, this will definitely become our most proud work, so its selection must be the best." Feng Jingyu said.

Shi Yuan nodded, and said: "The defense and attack power must be the best, and the refining materials must also be the best. However, with the storage of our Association of Craftsmen, there is no such high-quality materials. I have to look for it."

Feng Jingyu asked, "Teacher Shi thinks, what material is the best? I can look for it."

"The best materials currently known in the Apocalypse Continent are purple gold, celestial meteorite gold, dragon-patterned silver gold, black gold, and diamond gold. For defense, use celestial meteorite gold or diamond gold to attack. The material can be purple gold or black gold, and the appearance can be black gold." Ishihara said.

"These materials are not easy to get, right?" Feng Jingyu asked.

"These materials are all top-notch materials, and they are generally priceless. So if you want to get them, you have to rely on luck." Ishihara said.

"Where do these things come from?" Feng Jingyu asked.

"These materials have mines, but there are very few materials for development, and they are monopolized by all big families and big forces. We may have such materials at the headquarters of the Association of Craftsmen, but they are all very precious. Under normal circumstances, they will not Use it."

Ishihara said: "These materials, even the spirit emperor and the spirit god, will be used to refine spirit weapons. If we take the second place, then the choice will be great."

"Maybe we can use it together, using the best materials in key parts, and some parts can be replaced with other materials." Feng Jingyu said.

Shi Yuan nodded and said, "That's okay. At present, we first refine a smaller model with the most common materials to see if it can be successful. After we have experience, we will use good materials to refine it. , So no material is wasted."

Feng Jingyu nodded in agreement, and then the two began to move some common materials from the material library and began to play tricks.

To be honest, Feng Jingyu was a little excited. After all, these things are his ideas, integrating a large number of elements. If they can be successful, then he will complete things in this world that cannot be accomplished by science and technology on earth. .

The two of them were like two lunatics. They locked themselves in the refining room. Ishihara hadn't seen a visitor for more than half a year. No matter who came, people from the Refining Masters Association only said that Ishihara was studying important spiritual weapons , See no one.

So now in the Northern Rong dynasty, a kind of talk is beginning to spread, and Ishihara will refine a very remarkable spiritual tool.
