When Lin Feng stepped into the mysterious ancient battlefield again, he felt very different. The last time he entered the ancient battlefield, he only had a few hundred million world combat power.

Therefore, entering the ancient battlefield is also cautious, and even ready to use the space disk and space-time imprint at any time, it can be said to be extremely cautious. Even the "Leihai" in the ancient battlefield could not enter, which should be the core of the ancient battlefield.

But now, Lin Feng has long been different from what he used to be, with a total of 5 billion world battle strength, just like walking around in a leisurely court, walking in the ancient battlefield, without feeling the slightest threat.

Finally, Lin Feng came to the "Leihai" again.

The last time, Lin Feng couldn't enter Leihai. Just approaching Leihai, he would feel severe danger. It seemed that once he stepped in, he would face a threat of life and death.

But now, Lin Feng can hardly feel any danger. Five billion world battle power is enough for him to deal with any threat.

"Let me see, the real secret of this ancient battlefield."

Lin Feng was in high spirits and made up his mind.

"Whoosh".

Lin Feng's figure flashed, and he directly stepped into the sea of ​​thunder.

"Boom".

Lin Feng stepped into the sea of ​​thunder with one foot, and the entire sea of ​​thunder "vibrated" violently, as if a drop of water had dropped into the scalding hot oil at once.

Lei Hai vibrated violently, and terrifying forces swept towards Lin Feng in an instant, as if a rolling wave drowned Lin Feng.

Lin Feng felt a lot of powerful boundary rules fluctuations in it, and these boundary rules can still mobilize a certain amount of power, which is incredible.

The masters of each rule, if they were alive, are probably two-star supreme beings of the tens of billions or more, and they are definitely not one or two, but at least ten or more, and even some of them are vaguely more than 100 billion.

Therefore, this huge sea of ​​thunder has been formed. Without billions of worlds, it is impossible to step into the sea of ​​thunder. Even a billion-level supreme being hastily stepped into it is very dangerous.

One after another, the power of thunder swept towards Lin Feng fiercely. However, there were phantoms of the realm floating above Lin Feng's head, and terrifying power permeated his body. Let these thunders slam on him, and stay still.

With the power of five billion worlds, what other power can shake it? If the owner of the rules in this sea of ​​thunder is still alive, then Lin Feng is still afraid.

But the masters of these rules are all dead, and now there are only residual rules left, why would Lin Feng care? However, Lin Feng also saw some clues from so many rules, which strengthened his inner guess.

This ancient battlefield must be the last era, or the battlefield of the last era. In short, it is definitely not the battlefield of this era. With the current situation in this era, how could so many two-star Supremes fall?

"Defining stone, so many delimiting stones!"

Lin Feng also did not forget his purpose. When he stepped into the sea of ​​thunder, he saw that in the sea of ​​thunder, there were densely packed delimiting stones, one after another, floating in the sea of ​​thunder.

Moreover, the quality of these delimiting stones is quite high, even far higher than Lin Feng thought. If you grab a handful, they are at least comparable to hundreds of ordinary delimiting stones, which can be almost 200 worlds.

It is unheard of for such high-quality delimiting stones to appear in large numbers.

Lin Feng entered this ancient battlefield for the purpose of the delimiting stone. Therefore, he was not polite and directly began to "sweep" the delimiting stone in the sea of ​​​​lei. One by one, all were swept away.

Lei Hai was too big, and the deeper he went, Lin Feng felt the pressure. Fortunately, he has the power of five billion worlds to protect him. Even if Lei Hai's pressure increases tenfold, Lin Feng can still withstand it.

And the number of delimiting stones he "scraped" is also increasing.

Ten thousand, one hundred thousand, one million...

In a blink of an eye, Lin Feng had scraped almost two million delimiting stones. Although the quantity seemed small, the quality was excellent. The worst delimiting stone can hold almost 200 worlds. What does this mean?

It means that these two million delimiting stones, once the source of the world is sufficient, can grow at least 400 million worlds!

This kind of harvest is far beyond Lin Feng's imagination, and this is just the beginning. He has not even been able to explore one-fifth of Lei Hai, and there are still a lot of delimiting stones "waiting" for Lin Feng to "scrape". .

As Lin Feng went deeper and deeper, the quantity of delimiting stones he harvested became less and less, but the quality became higher and higher.

"Huh? This delimiting stone, a one-star delimiting stone?"

Lin Feng's eyes suddenly lit up. He saw a few delimiting stones in front of him, which seemed to be different. Immediately grabbing it, there are five delimiting stones, all of which are one-star delimiting stones.

And the quality is very high, it is a million-level delimiting stone.

Just these five one-star delimiting stones can increase Lin Feng's combat power by millions or even tens of millions of worlds.

As Lin Feng went deeper and deeper, he encountered more and more one-star delimiting stones, and the quality was getting higher and higher. Now his most urgent thing is to improve his strength, so the delimiting stone is the key.

He knew that, like the last mission of Ganyu Supreme, he had obtained a full nine two-star delimiting stones. This kind of thing can be said to be something that can be met but not sought after. There are only a few people who can be like Ayong, the supreme leader of Ganyu, who has a deep background. Who would come up with so many two-star boundary stones?

Therefore, Lin Feng is very clear that such an opportunity is only one time, and it can be met but not sought. If he wants to get more delimiting stones, he has to find another way.

This mysterious ancient battlefield was the "Holy Land" that Lin Feng couldn't give up. He had to "sweep away" all the delimiting stones here before leaving.

"Million-level one-star delimiting stone!"

Finally~www.wuxiahere.com~ Lin Feng has approached the core area, and he has also discovered some tens of millions of delimiting stones. These tens of millions of delimiting stones are only a few or dozens of them when they are discovered.

It was a huge gain, and Lin Feng was naturally overjoyed. But it wasn't over yet. Lin Feng continued to go deeper. He was close to the core area, and he clearly felt the strong rule fluctuations.

This kind of rule fluctuation is larger than the rule fluctuation of any delimiting stone that Lin Feng has contacted.

"Swish".

When Lin Feng dispelled the thunder around him, within a million miles, everything became "calm". Lin Feng finally "saw" the two delimiting stones.

These two delimiting stones, like the stars holding the moon, are surrounded by many delimiting stones.

Even the outgoing fluctuations in the rules made Lin Feng feel a little bit of pressure, so he had to use all the power of the realm in his body.

Moreover, Lin Feng was under pressure and kept walking towards the two boundary stones. The closer he got, the more excited Lin Feng became, and even his excited body couldn't help but tremble slightly.
