Thinking of this, Chen Tian smiled and said, "Junior brother is out of here, what to do if you follow or not."

"Since you and I are brothers of the same school, we should support each other and work together to carry out the path of immortal cultivation."

"Not to mention that we all like the art of explosion so much, we can be called confidants."

Chen Tiandao: "What is a confidant? A confidant means having blessings and having difficulty. Senior brother, can I not teach you a wonderful method?"

"If the senior brother encounters danger in the future, can you not contact the elders in the family and help the senior brother?"

Qin Yundi nodded firmly: "Senior brother, it's Yundi who is here to see you. Yundi thanks you."

Chen Tian smiled and said, "If you want to talk about the ways to improve the explosion, it's not without it."

Seeing Qin Yundi, who had originally squinting his eyes, staring at him with scorching heat, Chen Tian's mouth slightly raised.

He smiled and said, "Junior brother, try to follow my method and rub two hydrogen and oxygen divine thunders first."

Qin Yundi nodded. At this time, the lake water in his hand was almost electrolyzed and turned into hydrogen and oxygen.

He took out a talisman from his arms, quickly carved a talisman to absorb all the hydrogen and oxygen into the talisman.

The cost of this kind of Qi-gathering Talisman is still very cheap, and it is less than one-tenth of the cost of Qin Yundi's writing of the Thunderstorm Talisman.

Of course, there is also an upper limit for the gas absorption of gas by the gas collection talisman, and Qin Yundi soon felt full.

At this time, the Qi Gathering Talisman emits fluorescence, which looks very beautiful.

Qin Yundi took out the second Qi-gathering Talisman and began to inflate it.

...

Soon, two qi-gathering talismans filled with hydrogen and oxygen appeared in Qin Yundi's hands.

He filled in a simple rune of detonating thunder fire on the two Qi-gathering Talismans and handed it to Chen Tian.

Chen Tian nodded slightly. The son of Qilu is the son of Qilu. This holy son just taught you a trick to electrolyze water and rub thunder.

You can immediately learn from it and use the gas-gathering talisman to store the electrolyzed hydrogen and oxygen, which can directly meet mass production.

It is worthy of being Qin Lavoisier Yundi!

Chen Tian raised his mouth slightly and cast one of the Qi Gathering Talismans to sacrifice to the open space by the lake.

When the Qi Gathering Talisman flew out more than 20 meters away, Chen Tian pinched the magic trick and pulled the detonation talisman on the Qi Gathering Talisman.

Boom ~

Suddenly, a loud bang was heard, and another blue lotus bloomed.

On the originally extremely flat beach, a large pit seven or eight meters square instantly appeared.

This big pit is one person tall, and there is a layer of transparent crystals on the bottom.

Looking at the big pit, Qin Yundi's eyes lit up: "Senior Brother, the power of this talisman can threaten the strong man in the Foundation Establishment Stage."

"It's just that the range of killing is smaller, and the speed of talisman sacrifice is not fast enough, so it's easy to be avoided."

Chen Tian nodded, slowly walked to the ground of the big pit, and picked up crystals.

He wrapped these crystals in spells and wrapped them into small balls the size of a fist.

Put this ball on the ground and Chen Tian slowly retreated twenty meters away.

After thinking about it, he felt that it was still a bit insecure, so he took out the Xuanwu Shield.

Turning around and looking at Qin Yundi, Chen Tian reminded: "Come on, junior brother, hide behind me, be safer."

Qin Yundi narrowed his eyes and smiled: "Senior brother is worried too much. I am still not afraid of this kind of thunder explosion talisman."

Chen Tian nodded thoughtfully, and a rich black light emanated from the Xuanwu shield, condensing a black shield.

After confirming that his whole body was defended by the energy cover of the Xuanwu Shield, Chen Tian inspires the detonation rune.

Boom~!

It was still the same loud noise as before, and it was still the light blue flame lotus as before.

However, this time, there were many dense small pits in the big pit that were seven or eight meters square.

These small pits penetrated deep into the beach, and I don’t know how deep they penetrated.

It is worth mentioning that there are also some blue rocks standing in Jingyue Lake Pan.

There were several blue rocks within the explosion range of the thunderstorm talisman, which was shocking at this time.

On each huge rock, high-speed crystals were blasted out of large pits, cracks, and even directly broken.

Chen Tian could feel something hitting the Xuanwu shield just now, and his hands were numb.

However, Chen Tian’s strength is strong enough, and the defense of the Xuanwu Shield is indeed strong enough, so the problem is not big.

...

But when Chen Tian turned around and looked at Qin Yundi, he couldn't help laughing.

But Qin Yundi, who was originally dressed in a clean and tidy manner, became like a beggar at this time.

The clothes were covered with holes, and the good protective clothing was directly scrapped, and his face was extremely pale.

Obviously, some fragments shot on Qin Yundi just now, causing the kid to almost be reimbursed.

Fortunately, although the protective clothing was scrapped, it still blocked the last aftermath.

Qin Yundi was just surging his qi and blood, and his injuries were not serious.

He swallowed and said shockedly: "What a powerful force, it is enough to hurt the late stage of foundation building!"

Although Qin Yundi once used 6,000 thunder talisman formations to kill powerful monsters in the late stage of the Golden Pill stage.

But the power of those single thunder and explosion talismans can only hurt the initial and mid-stage foundation building.

More importantly, 6,000 thunder talismans almost broke Qin Yundi!

However, the Yin-Yang Thunder Talisman invented by Senior Brother Shengzi is not only one-tenth of the cost, but also simple to make.

After adding hard objects, the lethality has risen sharply, which is even more powerful than the Thunderbolt Talisman.

If he can equip 6,000 such detonation talismans, Qin Yundi, the peak of the Golden Pill, dares to be evil!

...

Looking at Qin Yundi with a shocked face, Chen Tian smiled slightly: "This is just the simplest version."

"If Junior Brother Yun Di is interested, you can replace these crystals with harder spiritual iron steel beads."

"Under the impact of a powerful explosion, these spiritual iron steel balls shot out from all directions, and the power can be imagined."

The light in Qin Yundi's eyes became more and more powerful, and he felt that his senior brother opened a new door for him.

In the past, Qin Yundi studied thunder talismans and was always exploring how to improve runes and formations.

But I didn't find that I wanted to increase my lethality, so I could add something else.

It is like the Yin-Yang Divine Thunder that added Yin-Yuan Zi and Yang-Yuan Zi, and the Yin-Yang Armor-Breaking Divine Thunder that added Ling Iron Steel Pearl.

If it can be really developed, it will definitely cause storm waves in the entire Donghuang Thunder Talisman market!

Seeing that Qin Yundi was already stunned, Chen Tian smiled and said, "Of course, this is still a simple version."

"If Junior Brother Yun Di can make these spiritual iron beads shoot in the determined direction like bows and arrows."

"Then the operability of this kind of divine thunder is even stronger. Just imagine where the lethality is pointed, just imagine?"

Listening to Chen Tian's words, Qin Yundi narrowed his eyes for more than ten years and stared at the boss, completely stunned.

...

A picture appeared in his mind, which was a weak cultivator in the Qi Refining Realm.

The monk held the magical thunder magic weapon he had developed in his hand and stuffed a Yin-Yang Thunder Explosion Talisman into the magic weapon.

Then he lifted up this magic weapon, and suddenly activated the thunder talisman to shoot out the characteristic spiritual iron steel ball at the peak of the Foundation Establishment Period in front of him.

Only a loud noise was heard, and the monster in the foundation-building stage was penetrated by spiritual iron steel balls.

Qin Yundi had a strong intuition in his heart, if this magic weapon could be invented.

He will follow the Holy Son Senior Brother and enter the history of the Holy Land of the Divine Sky!
