Su Yi smiled and said, "They all have a cool-down period. They need to rest for a while after a round."

"I understand." The burly man nodded.

"Let's go." The old man with the bark shouted and rushed out first.

Yao Ziyan and the Four Vajra retreated accordingly.

The fierce battle lasted for half an hour, and just when the old man Bark and others were unable to hold on any longer.

Su Yi summoned the Plant Shooter, the Pea Shooter and the Pepper Shooter.

They also took out two of the goblins' latest catapults. These two catapults were fifty meters long and could project up to 20,000 kilograms of stones at a time, so their destructive power was considerable.

With their help, I managed to hold on for a while.

Later, Su Yi asked Gu Zhuyue and others to come out to help.

However, as time went on, everyone's spiritual energy was almost exhausted. Without the support of spiritual energy, they could not stop the attack of the skeleton army.

What is even more dangerous is that powerful characters, Titan Skeletons, have gradually emerged among the skeleton army.

These guys are generally around thirty feet tall, have extremely strong defense, and are extremely powerful.

It was difficult for the people present to resist.

The current situation inevitably requires the help of the Rock Spirit Crystal.

But Su Yi didn't want to watch the Rock Spirit Crystal being consumed, so he turned to the [Intelligent Chariot] and asked: "No. 2, can you fly?"

If you can fly into the sky, you can avoid the siege of the skeleton army.

Once he recovers, all problems will be solved.

The [Intelligent Battle Vehicle] immediately said, "There is a no-fly restriction in place here. We cannot fly."

"Trouble." Su Yi frowned deeply.

[Intelligent Chariot] suddenly reminded: "Su Yi, how about you try digging a hole in the ground?"

"That's right." Su Yi's eyes lit up.

If you just dig a hole in the ground and hide in it, defense will be much easier.

Just do it!

Su Yi used his digging ability to easily break through the ground.

But what he didn't expect was that there were actually a large number of monster skeletons underground, and their combat power was quite strong.

This is like touching a hornet's nest. Not only do you have to resist attacks from the ground, but you also have to guard against sneak attacks from underground.

There is no other way but to use the Rock Spirit Crystal to create Rock Spirit to resist.

Looking at the shrinking mountain of the Rock Spirit Crystal, Su Yi's heart was bleeding.

It was not easy to obtain a piece of Xirang, which helped the Yanling Zhenjing recover a little. After this battle, the horror was about to return to its original form.

...........

The fierce battle lasted for a day.

Everyone was injured, exhausted and out of breath, and had basically lost their fighting ability.

The loss of the Rock Spirit Crystal was even greater, and the main body of the mountain was less than one tenth of its original size.

Fortunately, Su Yi has recovered to the ninth level, and is able to fight even against a strong man in the second level of the True Spirit Realm.

He had no choice but to continue waiting.

After collecting all the people into the world fragments, he summoned Xiao Jian and ordered him, "Xiao Jian, open the way! Go straight ahead."

The location of the undead is twenty kilometers ahead.

Xiao Jian released sword energy and rushed forward madly.

Now, after absorbing the energy of the Sword Origin Stone, he has been promoted to the fifth level of the Divine Realm and is extremely powerful.

The dazzling sword light swept across, and wherever it passed, no matter what type of skeleton it was, it would be crushed instantly.

Su Yi followed closely behind, and in order to maintain his condition, he did not make a move easily.
