I have a full-time hero system

Chapter 287
At the critical moment, Yuan Xiao didn't even think about it, he immediately took out Zhitian Sword from the system.

Zhitian Sword, even in the real world of comprehension, is a rare divine weapon.

The sword, after all, is a metal substance, so it must have good electrical conductivity.

"Mu Lan, continue!" Yuan Xiao threw Zhitian Sword over.

When Li Mulan grabbed it, she froze for a moment.

The divine sword is not something anyone can have.

When Li Mulan's aura touched its sword spirit, both sides were confirming the existence of the other.

However, the thunder and lightning in the sky suddenly became violent.

In the Dao of Heaven in this world, there are no practitioners.

Li Mulan's existence was already against the sky.

The thunder tribulation this time is Heaven's way of urging him to kill him.

You can be a cultivator, but you can only be ordinary.

Crossing the tribulation is doomed to fail.

But the addition of Zhitianjian changed this situation.

Li Mulan's aura, mixed with the sword spirit, rushed straight to the sky.

At the same time as the sky and the earth changed color.

Heaven made a move.

This kind of existence against the sky is absolutely not allowed.

"Crash!" Lei Jie fell again.

This time it seems to be thicker.

Curse!

Li Mulan held the Heavenly Sword in her hand, and she was not afraid of facing Thunder.

The two sides meet again in the air.

"哗啦啦" Excessive force began to burst out.

"Not good!" Wang Lingyun was taken aback, and she hurriedly called out her martial spirit.

The green dragon circled around this area, stopping the overflowing lightning.

Yuan Xiao also clenched his fists.

I did everything I could, and in the end it all depended on Li Mulan's own luck.

It is a pity that part of the aura in Li Mulan's body has merged with the sword spirit, and now there is even less left.

She couldn't resist Thunder Tribulation.

At this point, Yuan Xiao is helpless.

He raised his wrist and looked, the time was 11:59:59.

Tick ​​tock!

For the final swing, the midnight bell of Fengyun Pavilion rang.

Li Mulan's exhausted divine palace suddenly lit up again.

Ziwu Sansheng Jue has worked.

In an instant, her aura was fully restored automatically.

Heaven-defying exercises, coupled with a heaven-defying sword, accompanied by a heaven-defying determination.

Li Mulan's whole body turned into a ray of light, rushing straight to the thunderclouds above.

"Break it for me!" She swung the long sword in her hand, cutting off Leiyun with one blow.

"Pa——" a brilliant light lit up in the sky, and the thundercloud dispersed and turned into aura.

And all the remaining spiritual energy quickly poured into Li Mulan's divine palace and was absorbed by the golden core inside.

Yuan Xiao and Wang Lingyun stood upright.

The movement gradually died down, and Li Mulan also slowly fell from the air.

The clouds are scattered and the moon is now.

The golden core slowly sank into Li Mulan's divine palace, which meant the end of this tribulation.

Wang Lingyun shook her head: "This is what you said about crossing the catastrophe, the movement is so big."

"How?" Yuan Xiao waved his hand in greeting.

After Li Mulan got used to it, she floated over.

"It feels like something is added to the body, the five senses and others are completely different." Li Mulan replied.

Yuan Xiao smiled: "When the Nascent Soul is hatched in the future, it will be like a doppelganger, you have to get used to it slowly."

Li Mulan nodded.

After such a fuss, the aura in this area was completely consumed.

Li Mulan pondered: "I need so much spiritual energy now, no wonder the teacher reminded me that this road is not easy to walk at the very beginning."

Yuan Xiao patted her on the shoulder: "Do you regret it?"

"No, even if the laws of heaven forbid, I will go against the current." This is her determination.

Yuan Xiao is very satisfied, this is the kind of heart that Daozu has.

Zhitian Sword was given to Li Mulan, and Yuan Xiao simply took out "Zhitian Nine Swords".

"This is a martial art in the realm of comprehension," Yuan Xiao urged, "it is extremely powerful when used.

Don't be in a hurry to practice, after you have consolidated your cultivation, find a place where no one is around to practice.

Start to control the power, don't go all out, otherwise, the city may be destroyed. "

Li Mulan's face flushed red, and she hugged the secret book tightly.

This is something that has been long awaited.

Yuan Xiao removed the surrounding formations and returned to his yard.

It was quiet all around, as if the movement just now didn't affect anyone.

His eyes fell on Dongfang Xiaoman's flowers and plants again.

What happened today made him understand a little bit.

The fountain of life can indeed be transformed arbitrarily, and even become spiritual energy.

So, what kind of substance is this thing?
No one in the world knows.

This is not reasonable.

That's right, if it is reasonable, it will not be called the world.

The sun comes up and life goes on as usual.

In the following days, Yuan Xiao continued to teach students the periodic table of elements.

It's a series after all.

It's just that he started to give a simple explanation on the application of some elements.

Students are even encouraged to experiment to discover these elements.

Of course, with the current ability of students, there is still no way to find out.

There are still people clamoring on the Internet.

Including Lirenwell's cultural circle, that is, Yuan Xiao's old rival Xie Dingfang Li Zhongzheng and others.

And Singer on the Federation side.

From time to time, he would refute and satirize Yuan Xiao a few words.

This caused his proud index to add and subtract every day.

Overall, however, there is little fluctuation.

Over time, however, good results started to trickle in.

The first is the National University School of Chemistry in the Principality of Princes. The team headed by Hou Jiaxi claimed to have discovered inert gases.

This discovery is fast.

After all, the method of discovering inert gas was provided by Yuan Xiao.

Hou Jiaxi and others just need to follow the steps.

The reason why the announcement was delayed until now is because the rest of the relevant information has also been verified by Hou Jiaxi's team.

Including the atomic weight of the noble gas, as well as the atomic number, that is, the number of protons, etc.

A series of data shows that it completely conforms to the periodic table of elements announced by Yuan Xiao.

This announcement once again cast the eyes of the world's chemical community on Yuan Xiao.

Hou Jiaxi vowed that the discovery of inert gas will play a major role in its extended application fields, industry, medicine, cutting-edge technology and daily life.

Along with this list, there are some confirmed noble gas applications.

Such as the advent of new welding technology.

Such as the production of neon lights, etc.

For example, the detection of cosmic radiation.

Such as the improvement of deep-sea diver's breathing apparatus.

Such as the development of new drugs.

and many more.

This is the world, on the basis of the 63 elements that have been discovered, the discovery of long-lost new elements.

At the same time, it also proved the correctness of Yuanxiao's periodic table of elements.

However, Federation's Singh did not give up.

He called the discovery "an extremely fortuitous result."

Still retain the persistence of arranging elements by atomic weight.

Unfortunately, his obsession soon disappeared.

Just a few days after noble gas was discovered.

The research team of the Pajaslen Alliance announced the discovery of the No. 27 element cobalt mentioned by Yuan Xiao.

And for cobalt measurements, the atomic weight is indeed greater than that of nickel.

Moreover, the obtained data is exactly the same as what Yuan Xiao announced.

The atomic weight of No. 27 cobalt is indeed larger than that of No. 28 nickel.

This makes Singer's theory of atomic weight arrangement completely turned into a mistake.
