The four elders smiled at the Great Elder with bad intentions, and the meaning was clearly to say: How about it, do you want to try it?

The last time the Great Elder was testing the paper cannon, he accidentally blasted into the Hidden Scripture Pavilion, and was almost split by the golden armor guards. This time he didn't dare to try again, the chain paper cannon was even more powerful, and it was not a small sin to burn down the council hall if it was not well controlled.

The Great Elder didn't touch the chain paper cannon, but the Second Elder took it with great interest. After some temptation, I was also taken aback. This source kid is really bold enough, four runes are squeezed out of a spirit pattern "empty dang", and a paper cannon has thirty-two runes, what does his little head think.

"Young people have a lot of ideas. The second elder looked at Yuan Tian with kind eyes, and praised the chain paper cannon he made.

Yuan Tian hurriedly took out the remaining two paper cannons and put them all on the table. He is very confident in his work and will definitely be able to attract the attention of the master.

He Tianao still looked cold, and casually picked up a chain paper cannon. He tentatively seemed to be inadvertent, and then aimed the muzzle of the gun at the main entrance of the council chamber.

What is this for? Seeing the head of the house, Yuan Tian couldn't help but be taken aback, and Steward Wang also showed a stunned expression. The three of the Great Elder, Second Elder, and Fourth Elder did not show a surprised expression, but on the contrary, there was a little look of anticipation.

It wouldn't be to test the power of the chain paper cannon here, it seems that the head of the sect is confident that he can control the fire, but why did he put the muzzle of the cannon at the door, does he also want to try it in the Hidden Scripture Pavilion.

Just when Yuan Tian was thinking about it, He Aotian opened fire. The sound of the cannon was very small, and at the same time, four small purple fire flowers flew out. The flight speed is very fast, silent, like a purple ghost.

"Poof!"

There was no expected scene of the purple fire blooming, and the purple fire flower was extinguished before it could fly out of the council room. Because a big golden hand appeared in front of the four purple fire flowers, grabbed them all and shook them hard.

That's right! It was the golden-armored guards who appeared in the council chamber, apparently summoned by the master. The purpose of the shot was to test the power of the chain artillery.

Is this extinguished? Yuan Tian instantly felt a little lost, originally expecting the chain paper artillery to have a wonderful performance. Now it's so simple to extinguish, which makes him feel a little depressed. This is my own big killer, and it's too powerless to be pinched and extinguished like this.

"It's okay, if it's a lot of it, it should be a little useful. ”

What He Aotian said was not salty, and his evaluation of the chain paper cannon was only a little useful, and it still needed a large number.

"If you need anything, continue to mention it to Steward Wang, and he will try to satisfy you. ”

This sentence still exposed He Aotian, although he pretended not to care much about the chain paper artillery, but in fact, he was very happy in his heart. He didn't show it on his face because he wanted to maintain the serious expression characteristic of the head of the house. At the same time, he was also afraid that Yuantian would be proud of this, and pride would make people not know how to make progress.

What a shrewd person Yuan Tian was, he immediately grasped the key information from the words of the master: if there is a need to continue to mention, that is, he can withdraw more spirit stones! He suddenly thought of one thing, that is, a material that he had been looking for, which could be used to replace the spirit stone carving seal.

The size of the spirit stone is limited, and the large runes and spirit patterns cannot be carved, so there is an urgent need for a material that can replace the spirit stone to transmit spiritual power. It is best for this material to be attribute-free and can be infused with spiritual power of any attribute without conflict.

The head of the sect put aside these words, picked up the three chain paper cannons, turned around and left, leaving only the three elders looking at each other.

Now that the heads are gone, there is nothing to do with the rest of the people. Yuan Tian followed Wang Jianghua to the Foreign Affairs Administration Office first and told him the requirements for what he needed. This thing should be as good as the spirit stone, and it should be larger than the spirit stone, and the price should be more affordable than the spirit stone.

Wang Jianghua pondered, there is really this kind of thing in the sect's warehouse, but no one uses it now. This kind of thing is called a spirit foundation stone, and it is a kind of thing that is dug in the process of mining spirit stones. The spirit foundation stone is the same as the spirit stone, it can be used as the transmission of the spirit stone, and it also has a characteristic that it has no attributes.

Since the spirit cornerstone stone is an associated mine, the output is quite small and the use is not large, so few people collect this kind of thing. The one of the spiritual foundation stones in the warehouse of the Tian Yuan Sword Sect was there, and no one had ever exchanged for it. The spiritual power contained in these stones was very small, much less than that of low-grade spirit stones. For the monks, this kind of thing is big and stupid, and if you put it in a Qiankun bag and stand in too many places, it will not work well when you use it. So far, no disciple has exchanged points for it, and one is idle in the warehouse.

Since Yuan Tian is in need, he will give it to him, and it is useless for the Wang steward to keep it anyway, and besides, the head of the house has already spoken, so that Yuan Tian can mention it if he needs it.

This spiritual cornerstone is a transparent rectangle, which at first glance looks like a large crystal. The entire spiritual foundation stone is transparent, and what it contains is pure attributeless spiritual power. The advantage of non-attribute spiritual power is that no matter what kind of exercises the monk practices, he can absorb it. For Yuantian, no matter what attribute the spirit rune is, it can be used to engrave seals and make runes. Looking at the size of this spiritual foundation stone, it is not a problem to use it to carve the spirit pattern template.

Good thing, this is simply a baby tailored for the printing business, Yuan Tian is holding the rectangular spiritual foundation stone like holding a child. If it weren't for the fact that the king was in front of him, he really wanted to kiss the two spiritual cornerstones.

With this thing, you can reverse-engrave the spiritual frame of the paper cannon. When you want to draw a spirit pattern, you only need to aim at the rune paper and cover it hard.

The role of the spirit foundation stone without attributes is not tight, and it can also carve spirit patterns of various attributes on the front and on the reverse side. Since the spirit foundation stone is not limited by attributes, Yuan Tian wants to try to connect the spirit runes of different attributes together, and at the same time inlay them in the "empty space" of the spirit pattern.

He didn't mention this idea to Steward Wang for the time being, and he didn't know if Lu Dao's idea would be successful, so he would test it himself first.

After taking away the spirit foundation stone, Yuan Tian took another fifty high-grade spirit stones from Steward Wang, and was still thinking about the hundred-year-old pink mahogany that was about to be auctioned at the black market fair. The speed of the shuttle is not high enough, even if it is only used to rush and not participate in the battle, it will be too time-consuming. If you encounter a strong enemy to escape, it will be even slower. This time, Gentian is going to make a new mahogany spaceship, and he has to change some of the runes on it.

Before, you couldn't add too much to the Wind Rune, but it was limited by the rune paper material. When you get a new material this time, you must add more wind runes.
