"I'm behind the scenes!" An Linyuan wanted to find some excuses, and temporarily suppressed the offensive momentum. Hearing the disciples of the Blue Fist School ask this, he immediately found the excuse.

"Without the support of the energy spirit stone, I, as strong as a ancestor, can only look at their long-lasting backs."

An Linyuan sighed in front of the nobles.

"I have only been 5 years, so much has fallen behind in my cultivation!"

An Linyuan looked around at the nobles surrounding him, and his morale was a little low.

"Think about it, if we can build the castle in front, there should be countless energy spirit stones waiting for us to harvest. With sufficient energy spirit stone support, what level will our cultivation speed reach!"

The morale of the nobles began to rise again.

"Let's discuss first how to crack the attack of the castle in front." An Linyuan said after seeing the vanguard leader retreating back to the formation in shame.

An Linyuan arranged the Blue Fist Formation members to start digging a large tomb at the bottom of the cliff through his mental power.

This tomb will become a huge bait for the Eastern Empire's Western Expedition Army in the next five years.

The tomb began to dig from the bottom of the cliff of the castle where the Blue Fist Array was located, digging obliquely into the ground for several miles, digging to the hard basalt rock formation, and then extending to the garrison of the Eastern Empire's Western Expedition Army led by An Linyuan. 2 kilometers outside the castle wall, excavating the main coffin chamber.

An Linyuan prepared 200 billion gray spirit stones and placed them in tens of thousands of coffins.

An Linyuan arranged the blue fist formation and earth formation team members began to build various mechanisms around the main coffin chamber.

Six protective layers are created from the inside to the outside: automatic destruction device, long corridor combining stone baffles and traps, walls of iron and stone blending, protective layer of stone accumulation, protective layer of sand accumulation, and soil and stone covering layer with the same earth and stone covering layer as the surface of the tomb passage.

The members of the Blue Fist Great Formation Earth formation used the power of the formation to build the tomb in a very short time. According to An Linyuan's requirements, they forged a series of clues to the tomb.

"The purpose of our Western Expedition Army is the energy spirit stone!" An Linyuan began to enlighten the nobles of the Western Expedition Army in the command center's tent.

"When I left this land, I heard a legend."

An Linyuan told the story.

"I heard that in ancient times, there were energy spirit stones everywhere. The earliest people didn't know the function of energy spirit stones, but they just thought they could be exchanged for things. Until one day, a person discovered the use of energy spirit stones."

"The person who discovered the use of energy spirit stones was quick to cultivate and became a great emperor, unified this land and collected a large amount of energy spirit stones."

"When he died, he brought all the energy spirit stones he had collected throughout his life into his tomb."

An Linyuan looked at the nobles, and sure enough, the eyes of the nobles had already begun to shine.

"We just need to surround the castle in front and then look for that big tomb."

"As long as the natives in the castle don't come out to stop us, we will focus on finding the tomb and dig out a massive amount of energy spirit stones in the tomb."

"According to legend, the energy spirit stones buried in the tomb can buy the entire Eastern Empire."

After hearing this analysis by the national master, the nobles turned their attention to the direction of finding the tomb.

An Linyuan divided the work, and each nobleman divided the search area. He dug three feet into his respective areas to find traces of the tomb.

"Whoever finds clues to the tomb first will have priority excavation!"
